Renewable Energy Flat Plate Collector

The Rapid Depletion Of Conventional Energy Sources And...
Abstract
The rapid depletion of conventional energy sources and scarcity of fossil fuels are the major energy
concerns. The renewable energy such as solar powered energy can be harnessed by using solar flat
plate collector. A solar flat plate collector collects heat by absorbing heat from solar radiation. The
performance of solar flat plate collector mainly depends upon the characteristics of working fluid.
Conventional solar flat plate collector uses water as heat transfer fluid but it gives lower thermal
efficiency. Nanofluids have superior thermal and optical properties that can be used to increase heat
transfer rate. So our aim is to design and develop solar flat plate collector using Nanofluid as heat
transfer fluid. 1. Introduction
1.1. (a) Introduction – Flat Plate Collector
A solar thermal collector collects heat by absorbing heat from sunlight. A collector is a device for
capturing solar radiation.
Flat plate collector consists of:
1) a dark flat–plate absorber,
2) a transparent cover that reduces heat losses,
3) a heat–transport fluid (air, antifreeze or water) to remove heat from the absorber, and
4) a heat insulating backing.
In water heat panels, fluid is usually circulated through tubing to transfer heat from the absorber to
an insulated water tank. This may be achieved directly or through a heat exchanger.
1.1 (b) Introduction of Nanofluid
A Nanofluid is a fluid containing nanometer–sized particles, called Nanoparticles. These fluids are

Thermal Energy Conversion Essay
The demand for an efficient renewable energy source is a driving force in ongoing research.
Thermal energy conversion is one such potential source that is under constant investigation and has
endless avenues of possibility. The two requirements of energy production are efficiency and
renewability. Many possibilities exist for energy production including: Fossil Fuels (natural gas, oil,
coal, oilshale), nuclear, solar, wind, geothermal, biomass and wastes, & hydroelectric. Efficiency of
the use of these resource are directly related to the location and the demand in that location. For
example Hawaii is a prime candidate for the use of the oceans mechanical wave action, the thermal
gradient of the ocean, wind, and biomass from the high ... Show more content on Helpwriting.net ...
There are three types of energy converters producing electricity: closed cycle, open cycle, and a
hybrid system combining the previous two systems. Closed cycle OTEC systems use the warm
surface water to boil a fluid that has a low boiling point (e.g. ammonia). The pressure caused by the
expanding vapor is then used to turn a turbine. The turbine then turns a generator to produce
electricity. Cold water is then used to recycle the vapor back to a condensed state and the cycle is
repeated. An open cycle system directly boils the warm surface water. Operating at low pressure, the
steam that is created is channeled in turn to a turbine engine. The water vapor is condensed again by
cold water. If the condensed water is kept seperate from the cold seawater it can be used for
consumption or agriculture. Other by–products produced by the open cycle OTEC are a variety of
minerals. Both cycles produce electricity through the use of solar warmed water.
Steam Powered Turbine Engine
Capturing the power of steam is not a new idea but one that has been used for hundreds of years. A
jet of steam can readily do work on an object by the jet propolsion effect of steam escaping through
a small guided hole or by a stream colliding with a system of paddle wheels. Most early steam
powered machines used the principles of the latter. The system of paddles, or turbine, was used to
drive a shaft which in turn could drive any number of gear or belt driven mechanisms. The

Sun Solar Energy
How does the sun's energy affect water?
The sun which is a star in the middle of our solar system. The Sun is the primary source of energy.
Solar energy is light and heat from the sun. Solar energy is important to renewable energy. The
diameter of the sun is 1.39 million kilometers. The Sun's mass mostly contains hydrogen and
helium.
The use of sunlight is to supply the needs of humans like energy is a primary source to survival on
earth. The sun's energy is able to feed animal need's. Only green plants are able to convert the
energy from the sun into fuel and food. Most of our food and fuel are made through the sun with a
process of photosynthesis.
In early experiments a man name Joseph Priestley study the rays of the sun's energy onto mercuric
oxide and collected gas that was making heat from the sun rays and the mercuric oxide. In 1954
there was a group named "Association for Applied Solar Energy" this group was made in Phoenix,
Arizona. This group publishes books about how students or people in general want to learn how the
sun's energy works. Most people go to this group for ideas to work on projects and other. The sun
energy could work in many different ways to the atmosphere or there's a purpose to why the sun
shines so bright.
The sun has many rays or different levels of heat. The sun has three parts; the sun's interior, solar
atmosphere, and the visible surface. Inside the interior of the sun is the core, radiative

Sustainable Development And Energy Development : The G8...
The ongoing demand and patterns of industrial energy production and consumption are highly
unsustainable which may lead to face multiple challenges like global warming, greenhouse gas
emissions, geopolitical conflicts, consecutive fuel price rises and at last fossil fuel reserves
depletion. Worldwide all the developing countries are working to make a vibrant industrial sector
where entrepreneurs will make investments and thus opportunities will be created for new jobs. To
achieve sustainable development and alleviating poverty, most of the developing countries followed
the energy strategy to be focused on combating energy poverty by improving integration systems to
the reliable and renewable energy services, enhancing energy efficiencies and promoting renewable
energy to meet rising energy demand in industrial areas. Moreover, in reference to UNIDO (2007b),
potential of renewable and clean energy resources to protecting the environment is yet to be
realized. The G8 Summit Declaration of 7 June 2007 states: "Improving energy efficiency
worldwide is the fastest, the most sustainable and the cheapest way to reduce greenhouse gas
emissions and enhance energy security." [3,5–8, 52] However, in places without sufficient solar
energy supply, it's not possible to create solar energy system integration in industries or other
promising sectors. Now–a–days these industrial processes are using electricity or liquid or gaseous
petroleum fuels to meet the demand of industrial process

The Gap Between Energy Consumption And Energy Generation
CHAPTER 1: INTRODUCTION AND BACKGROUND Background
The gap between energy consumption and energy generation is gradually increasing and has become
a significant problem for both domestic and industrial applications. Furthermore, conventional
energy sources, like fossil fuels, are not fulfilling the energy needs of the developing world. And,
although they are still major energy sources for both the industrial and domestic sectors of the world
's economy, they are also responsible for many problem, such as environmental pollution and
climate change. Alternative energy sources are essential for, and the best solution to, both decreasing
the use of fossil fuels and fulfilling energy demands more healthily and cleanly. The major problem

The electrical energy method stores electrical energy with the use of batteries. This method is
generally considered the best, most prevalent technique when compared to others. The thermal
energy storage (TES) method, on the other hand, stores energy by changing the internal energy of
materials. There are three types of thermal energy storage; viz., sensible heat, latent heat, and
thermochemical energy storage. These are illustrated in Figure 1 below [1].
Latent heat thermal energy storage (LHTES) is a particularly appealing method due to its having a
high energy storage capacity, with it storing 5 to 14 times more heat per unit volume when
compared to the conventional sensible heat storage method. The latent heat storage method is a
system based on the charging and discharging of heat once a given storage material subject changes
phases from liquid to solid or from liquid to gas. Additionally, the latent heat storage system stores
energy at a constant, or near constant, temperature during the process of changing phases which, in
turn, depends on the characteristic structure of the phase change materials (PCMs).
Figure 1. Different types of thermal energy storage methods [2]
The Motivation of this Study
For three decades, many techniques have been used for the purpose of storing latent heat thermal
energy by applying different phase change materials. PCMs. are also known as latent heat storage
materials.

How Does Geothermal Energy Works?
How does Geothermal energy works? Geothermal energy works by the heat from the earth fossil in
the Earth's crust. This heat from the earth generates the electricity or heats homes from underground.
Power plants are apart of geothermal as well. There are three types of power plants. The three types
of power plant dry steam, binary ,and flash. These power plants are helping us produce more
electricity but in a renewable way.

It is a renewable energy after the heat is done it will deposit back to the ground. It is good that the
energy is renewable because it will last for years. Another advantage is that the geothermal energy
will not cause harm to the environment because this energy is non–polluting. Geothermal is also
resourceful in your homes as well,if you needed any heating or cooling somewhere in your house.
Lastly, geothermal will provide more jobs for people over in 20 countries so this will help improve
the economy.
Geothermal energy has disadvantages too. The water usage, high construction costs, and etc are
things that geothermal energy effects. It can be very dangerous and hard to drill into hard heated
rock. Sulfur dioxide, and silica emissions are harmful too and could possibly kill somebody.
Geothermal sites and locations contain harmful gases that are poisonous, and they can escape from

An Project On Water Resources
Objective: This project focuses on water resources in the region of ancient Eastern Arabia at the site
of As Safah, Oman. This site has archaeological evidence of metallurgical activities in the Iron Age
(c. 900–600 BCE), like kilns, furnaces and metal objects, still in very good condition. However, the
site is very far away from any natural water sources in the present day. Excavators did find sediment
and fluvial deposits suggesting that occasionally in the past the site had an inflow of water (Genchi,
Giardino, and Castelluccia 8). The objective of this project was to use satellite imagery to

Later that year and throughout 2013, excavators worked on the site, conducting surveys and digging
test trenches. Excavators found kilns and furnaces, layers of floor, and metal objects, like ax heads,
swords, daggers, and sledgehammer heads in very good condition. Excavators believe it is a very
well preserved site because of the formation and rapid movement of the desert sands which covered
up the site relatively quickly after it was abandoned (Genchi, Giardino, and Castelluccia 3–4). Sites
with similar metal deposits dating to approximately the same time have been found in the region, at
Ibri, for example, 50 km west of As Safah (Yule 39–40). The site itself has been delineated into As
Safah 1 and 2 based upon the deposit of material found on either side of a large dune belt (Genchi,
Giardino, and Castelluccia 3). As Safah 1 measures approximately 80,000 m2 and As Safah 2
measures approximately 17 hectares (Genchi, Giardino, and Castelluccia 11). The surrounding area
is made up of a wadi and dune deposits and the annual precipitation is less than 50 mm. As a result,
large amounts of rainfall will cause flash floods in this and surrounding low areas (Genchi,
Giardino, and Castelluccia 5–6). The site does not appear to be close to a fruitful water source. The
entire region is hyperarid and not conducive to farming. The rain comes erratically by the year, some
years being better than others (Potts 165). The location does offers other advantages which

The Building Of Building A Building
The building envelope is the building shell or enclosure that separates the interior of a building with
the outdoor environment. This physical separator serves as an important component to maintain a
comfortable and healthy indoor environment by transferring the air, water, heat, light and noise. The
components of an envelope typically include walls, fenestration, floors, roof and doors with
additional parts such as thermal insulation and shading devices. As discussed above, the climate is
an important factor when designing a building. A well–designed envelope with high performance
should be accustomed to the local climate. Accordingly, there are arid climate envelope, tropical
climate envelope, cold envelope and mixed cold/hot climate envelope which may be composed of
components such as sheets and blocks. The building envelope have a big influence on whole
building's energy usage. An energy effective building envelope design saved as much as 35% and
47% of total and peak cooling demands respectively. At the same time building code requirements
on envelopes have increased significantly. Although the codes and standards used in local and state
level of government varies in place, they all derivate from ASHRAE and International Energy
Conservation Code (IECC).
Walls are a major part of a building envelope and are expected to maintain a thermal and acoustic
comfort inside the building. The crucial performance factor of the wall is thermal resistance (R–
value) since it

Environmental Characteristics of Net Zero
Weekly assignment – Topic: Environmental characteristics of Net Zero Energy Buildings (NZEB)
1000 words research essay
A net zero energy building has a system to immensely reduce the total energy of a building by
implementing energy efficient technologies which gives counterbalance to the functional energy
needs supportive with renewable energy thus reducing the total energy consumption to roughly zero.
Zero energy buildings have certain characteristics, such as effective thermal insulation, using
renewable energy and using important passive strategies and energy control systems.
(P.Torcellini.2006)
The first character to highlight is effective thermal insulation, which depicts the glass walls, walls
windows, doors and roofing systems fully reinforced with low emissivity and solar control
strategies. And the adaptation of insulation methods in terms. This comprises of various insulation
properties in different weathers reducing cooling and/or heating loads (J.Eshraghi et al.2014). One
of the systems accounted for effective building insulation is the closed–cell spray polyurethane foam
(ccSPF) which is used to spray on walls and roofing systems to achieve control of building
temperature and indoor thermal comfort (Building Science.2014). Therefore, effective thermal
insulators acts as air barriers and provide more controllable environments. Furthermore reduces the
building's energy consumption and energy loss. In addition it also which reduces moisture intrusion

Water is pumped into solar panels where it is directly heated by the sun and then pumped into
storage tanks where it is stored. Direct systems are very effective but have a shorter life span when
compared to indirect systems. The reason being is that, the water chemicals erode the pipes and the
panels over time and hence have to be maintained regularly. Water inside the panels can freeze in
colder weather conditions which may result in damaging the system (Choosing a solar geyser,
2010). Figure 1–Direct System
Advantages of a Direct System
 Service water used directly from collector loop
 No heat exchanger – more efficient heat transfer to storage
 Circulation pump needs only to overcome frictional losses.
Disadvantages of a Direct System
 It is only convenient to use them in areas where it rarely freezes and the quality of water must be

really good.
Indirect systems use the same procedure but the geysers in this system have copper pipes that are
used as the heating coil. Water is separated from the water inside the tank by copper pipes in this
system. An antifreeze fluid circulates through the solar panels (Choosing a solar geyser, 2010). The
fluid flows through the collector and then through the copper pipes inside the storage tank. The
water is then indirectly heated. The indirect systems have a longer life span when compared to direct
systems as there is

As mentioned above, the demand for faster and smaller devices with higher performance is
increasing. However with increasing devices, there is increase in data generated. Large companies
like google, amazon, Microsoft and many others generate huge amounts of data which is stored in
large storage centres called Data centres. It is estimated that by 2020, around 35 zettabytes of data
will be generated every year [6]. To store and manage such large data, huge data centres are
required. However there are many challenges faced while operation of these datacentres.
One of the challenges faced by the data centres is land occupied by these data centres. Due to
increasing amounts of data, larger and more number of data centres are being built. For example,
one of the largest data centre by digital realty occupies 1.1 million ft2 of land and require 53

world and although the numbers might decrease after 2017, the space occupied will increase. Data
centre swill occupy around 1.94 billion ft2 by 2018 [7].
Second and the most important challenge faced by the companies are the amount of energy required
to manage data centres. All the data centres around the world use around 30 billion watts of energy
on average, which is equal to output by 30 nuclear power plants [6]. By 2020 it is expected that, US

"Simple living" even at its most extreme would not be enough to save the planet, according to
Jensen; "Simple living" is an active choice made by individuals to reduce their carbon footprint
through voluntary reduce, reuse, and recycle methods. The author expands on these ideas when he
cites Kirkpatrick Sale; "The whole individualist what–you–can–do–to–save–the–Earth guilt trip is a
myth. We, as individuals, are not creating the crises, and we can't solve them" (Jensen , pg. 478).
This means that individual effort can only go so far toward rebuilding the global ecosystem. Instead,
there needs to be a greater response from the groups that cause the bulk of the issues. Changes in
Governmental, corporate and agricultural organizations are imperative. Most importantly, we need
to have major technological breakthroughs in these sectors to stop the damage being done to the
planet. Current sources of renewable energy are great ideas, but are cost prohibitive and inefficient,
making widespread use impossible for most developing countries. Developing countries need new
advances in lower cost energy to break their dependencies, of environmentally costly fossil fuels.
Additionally, developed countries need to do more to deploy the existing technology and cut back
on the wasteful energy expenditures that go along with our creature comforts.

A Report On Passive Solar Architecture
PASSIVE SOLAR ARCHITECTURE INTRODUCTION:1 The last two decade has witnessed a
severe energy crisis in developing countries especially during summer season primarily due to
cooling load requirements of buildings. The energy consumption in buildings is quite high and is
expected to further increase because of improving standards of life and increasing world population.
Air conditioning use has increasingly penetrated the market during the last few years and greatly
contributes in the upsurge of absolute energy consumption. INTRODUCTION 2: Buildings account
for at least 40% of energy use in most countries. The construction sector in India is witnessing a fast
growth due to several factors. Some of the key growth drivers are increased demand for housing,
strong demographic impetus, expansion of organized retail, increased demand for commercial office
spaces by multinationals and IT (information technology) hubs, and coming up of SEZs (special
economic zones). The gross built–up area added to commercial and residential spaces was about
40.8 million square metres in 2004/05, which is about 1% of annual average constructed floor area
around the world, and the trend shows a sustained growth of 10% over the coming years. With a
near consistent 8% rise in annual energy consumption in the residential and commercial sectors,
energy consumption in buildings has seen an increase from a low of 14% in the 1970s to nearly 33%
in 2004/05. This is directly related to higher greenhouse gas

Abstract
Would painting your house a different color change its overall temperature? The project presented is
about the studies of the effects of different colored paints when applied to a building's roof. In the
studies it was discovered that a lighter color will not keep the heat trapped so a light colored house
will do well in a hot region, such as El Paso. A darker colored house would trap the heat, so a house
that is darker will serve a better purpose in a colder region. The materials needed for this project are
acrylic paint in red, white, brown. Apply the paint to three different boxes. When that is done set a
timer for 30 min and leave the boxes outside and record the temperatures. Once the time is up,
record the readings and input them into a chart. This will make it easier to analyze the results and
see the differences between each temperature. This experiment can help you decide what color is the
best option to paint your roof. Doing this experiment can help notice what colors regulate
temperature the best in different environment.
Introduction
How does the color of your house affect the temperature inside of it? The clothes you wear is an
example of this. On a hot sunny day you would rather wear a light colored shirt. If you were to wear
a dark colored shirt you would get warmer quicker than if you were in a light colored shirt. Since

An Experiment on the Synthesis and Characterization of...
Introduction In this experiment, the focus will be the synthesis and characterization of biodiesel fuel.
Biodiesel seems to have become the substitute for fossil fuel. It can also be an alternative for the
petroleum–based biodiesel. By having renewable resources such as corn, soybeans, peanuts and
other makes biodiesel a viable option. Using these resources wouldn't help alleviate the problems
with fossil fuel in the US. Biodiesel is produced from the transesterification reaction of vegetable
oil. Transesterification is the reversible reaction where one ester is converted into another by
exchanging an ester group with an alcohol in the presence of a base.
Experimental
According to the Laboratory Manual, there are multiple steps. We will need 50mL vegetable oil,
10mL methanol, 0.5mL 9M NaOH, diesel fuel, salt and ice. For preparation of Biodiesel, various
types of oil were available for synthesizing biodiesel. Measure 50mL of biodiesel into a 250mL

The Global warming being the major problem and the fact that consumption of non–renewable
resources is the reason behind it. The Future is considering complete utilization of renewable
resources as energy consumption, like wind energy, solar energy, tidal energy, etc. Particularly when
it comes solar energy, there are many techniques through which we can harvest solar energy as fuel
and use it for various applications one such application is solar air heating. In this paper, we study

South facing wall transpired solar collectors:
They are also called envelope–mounted, in this the building façade is fixed with perforated absorber
(see Figure 2). [1]
Figure 2
Rooftop mounted transpired solar collectors:
This type of transpired solar collector is installed on the building's roof top (see figure 2a) and these
types are used only when the stand alone types can't be used. Since These construction types have
flexibility in terms of tilt they can yield higher energy compared to that of stand alone types [1]

4. DISCUSSION
Let us see some of the researches done on transpired solar collectors and their outcomes.

Photovoltaic Transpired solar collectors:
This hybrid transpired solar collector (see figure 3) was developed to simultaneously produce heat
and electric energy using solar radiation [1]. In 1998 (Hollick) and 2008 (Delisle), conducted
experiment by bonding photovoltaic cells to transpired solar collectors, but results were not
satisfactory as the thermal efficiency turned out to be less than that of conventional

Persuasive Essay On Geothermal Energy
Geothermal energy is one of the cleanest sources of renewable energy, unlike some other sources of
renewable energy, geothermal energy is contained within a relatively small area, and doesn't affect
local wildlife, it also doesn't produce large amounts of toxic waste, and is nowhere near as
controversial as nuclear power. Unfortunately geothermal energy isn't used nearly as much as many
of the other types of renewable energy, in fact, there are only 12 operating geothermal power plants
in the US, a relatively small number compared to the 557 coal power plants that currently supply the
United States with its second largest source of power. Yet while the fields of solar and wind power
seem to be growing exponentially, geothermal energy remains relatively small.
Sadly the problem with geothermal energy isn't one that can be easily changed. The reason
geothermal power plants are so few and and far between is the overly specific circumstances that are
needed to harness the underground heat; geothermal power plants require hydrological sites with
naturally high temperatures of around 150 to 370, in the form of wells, hot water is then pumped out
of these wells is then pumped out of these wells, into one of three different systems, dry steam, dry
steam, or binary cycle. Dry steam is the simplest, but also the hardest to find. A dry steam system
will pump hot water out of the earth in the form of steam, since the water is already a gas, it can be
injected straight into the turbine

The Pros And Cons Of The Seebeck Effect
Energy loss is a problem encountered in every industrial process and everyday technology take
power stations for example. Electricity is generated by heat engines by which gas or steam powered
turbines convert the heat to mechanical energy then into electricity, however 70% of this energy is
lost as heat energy. Similarly in all electronics devices energy is lost through heat.
So we know that electricity creates heat mainly because or electrical devices warm up during its use.
But imagine how useful it would be to generate electricity from this heat created, in other words
using this lost energy which is in the form of heat to generate electricity so eventually you'd be using
every bit of energy to generate electric power. This objective can be reached by applying the
Seebeck Effect.
The seebeck effect is a phenomenon by which a temperature difference between two conductors or
semiconductors of ... Show more content on Helpwriting.net ...
It all started in 1981 when a German physicist called Thomas Johann Seebeck accidently found that
a compass magnet would deflect when a circuit with two different metals with different temperature
junction. He concluded that that there is an induced electric current in the circuit that deflected the
magnet according to ampere's law. So the voltage that was due to the difference in temperature
drives the current in a closed circuit.
In order To measure this voltage, a second conductor material which generates a different voltage
under the same temperature gradient must be used. Otherwise, if the same material is used for
measurement, the voltage generated by the measuring conductor would simply cancel that of the
first conductor. The voltage difference generated by the two materials can then be measured and
related to the corresponding temperature gradient. It is thus clear that, based on Seebeck's principle;
thermocouples can only measure temperature differences and need a known reference temperature
to yield the absolute

Thermal Energy And Thermal Energy
In thermodynamics, thermal energy refers to the internal energy present in a system due to its
temperature. The concept is not well–defined or broadly accepted in physics or thermodynamics,
because the internal energy can be changed without changing the temperature, and there is no way to
distinguish which part of a system's internal energy is "thermal". Thermal energy is sometimes used
loosely as a synonym for more rigorous thermodynamic quantities such as the (entire) internal
energy of a system; or for heat or sensible heat which are defined as types of transfer of energy (just
as work is another type of transfer of energy). Heat and work depend on the way in which an energy
transfer occurred, whereas internal energy is a property of the state of a system and can thus be
understood even without knowing how the energy got there.
In an 1847 lecture entitled On Matter, Living Force, and Heat, James Prescott Joule characterised
various terms that are closely related to thermal energy and heat. He identified the terms latent heat
and sensible heat as forms of heat each affecting distinct physical phenomena, namely the potential
and kinetic energy of particles, respectively. He described latent energy as the energy of interaction
in a given configuration of particles, i.e. a form of potential energy, and the sensible heat as an
energy affecting temperature measured by the thermometer due to the thermal energy, which he
called the living force.

The Effect Of Chlorofluorocarbon And...
Chlorofluorocarbon and hydrochlorofluorocarbon refrigerants have been widely used in traditional
cooling systems. These refrigerants accelerate the depletion of the Earth's ozone layer. Therefore,
adsorption air–conditioning technology attracted much attention recently as an alternative solution
due to its advantage of environmental friendliness. This system as it powered by waste and/or solar
heat can help to reduce required energy and thermal pollution. This paper presents an overview of
research which have been carried out on adsorption cooling systems powered by waste heat from
automobiles.
Many adsorption pairs have been studied. Zeolite–water as a working adsorption pair has been
widely used in automobile adsorption cooling systems. This pair has been powered by exhaust gases
from the engine due to its relatively high working temperature. Silica gel–water pair has been also
widely used in automobile adsorption cooling systems. It has been powered by waste heat from
water coolant in the engine due to its relatively low working temperature. Results show that this
technology can help in increasing overall engine efficiency and reduce thermal pollution from
engines. Various modifications in adsorption cooling systems are still required. One of the
bottlenecks which prevents the improvement of adsorption cooling technology is its relatively low
performance compared to conventional vapor mechanical compression technologies.

Bud Clark Commons : Public Housing Building And A...
Bud Clark Commons is a public housing building and a community resource center located in
Portland's downtown. The city of Portland is located on the state of Oregon, in the Northwest side of
the United States. It is situated between the Cascade Mountains and the Pacific Ocean, in the
Willamette Valley. According to the Köppen Climate Classification System (Figure 1), Portland falls
into the category of Coastal Mediterranean Climate: "Mild with cool, dry summer. No month with
average temperature of warmest months are over 22°C. At least four months with average
temperatures over 50°F." For ASHRAE 90.1 zoning map, Portland is in zone 4 with a marine
climate.
Portland's climate does not seem to be so humid along the year. The temperature does not fluctuate
dramatically during the year, but it does hit low and high temperatures that require both heating and
cooling systems to keep the buildings confortable. The city's climate is predominantly heating
requirering. The amount of rainfall during summer is very low, but it is very high during the winter.
The state of Oregon has adopted the IECC2012 building energy code, but by the time Bud Clark
Commons was designed and constructed, the IECC2009 was active in that State.
Heating
The first step that Holst Architects took to resolve heating system in the building was tightly sealing
the envelope of it. In order to make the building efficient, the façade had to be completely sealed to
guaranty no heated air leakage. They tested a

Geothermal Energy: How Does It Work?
What is it? How does it work?
Geothermal energy is the use of the Earth's heat as energy, hence geo– (earth) and –thermal (heat).
Geothermal energy is generated in the Earth's core by the decay of highly unstable radioactive
particles, which create heat when decayed. Geothermal energy then moves toward the surface
through the mantle, mostly near where tectonic plates (the geological divisions of the Earth) meet
via convection currents. This energy heats holes in the Earth that are filled with water, which are
known as reservoirs. This makes steam, which can be piped up to either district heating systems (to
heat houses, businesses, etc.) or geothermal power plants (to make electricity which are sent to
houses, businesses, etc.). One place ... Show more content on Helpwriting.net ...
They can do this by creating an artificial well, which is drilled and heated by humans. Geothermal
energy is still new in Vermont but is being recognized as reliable and feasible. While it is expensive
to install (as much as $5,000 per ton), it is worth the deal as it lowers the price of heating bills to
about 20% of the cost of using propane. Plus, a geothermal heat pump normally lasts for more than
20 years. Overall, the use of geothermal energy can vary from a small usage to a large usage. It is
most likely to be useful for smaller operations such as individual buildings because of the small
amount of space that they tend to take up. The fact that utility companies would need a large number
of geothermal heat pumps and space for them to power and heat a town or city is another reason of
why geothermal energy might not bode well for larger utility companies. However, they could be
useful on a larger scale for utility companies who want to make money as it is a cheap and
renewable energy source that doesn't harm the environment and is available 24 hours a day. Also, it
might be easier for a utility company to get a geothermal heat pump than it is for a person because
of the cost of the pump

The Use Of Deep Water Cooling In Lake Ontario
To begin with, Deep Lake Water Cooling, or DLWC for short, is an alternate method to air cooling
systems. DLWC is a method that is now used in Toronto. Basically, the concept behind it is that
water that is drawn from Lake Ontario for Toronto's water supply, is now drawn from deep within it
to be used for air conditioning. At the bottom of Lake Ontario, highly dense cold water can be
found. During winter, the water in Lake Ontario drops to cool temperatures, and this surface water
sinks to bottom of the lake when winter passes. Since this cycle continues every year, chilled water
will always be found at the bottom of his lake, allowing for this water to be a completely renewable
energy source. An initial study was conducted in 1981 and report

3. Hypothesis:
The greater the room temperature the greater the temperature of the solar oven.
4. Method:
1. Gather a shoe box and paint it completely black all over the box.
2. Wrap the flip of the shoe box with aluminium foil so the sun can reflect the sun rise into the base
of the shoe box.
3. Gather another box to place inside the base of the bigger box.
4. Put your two thermometers in the smaller box and check the room temperature on a regular basis
so you can compare the difference between your solar oven and outside temperature.
5. Cover the smaller box with cling wrap to absorb the heat within the box.

6. In the base of the box once the smaller box is in fill the rest of the space with crunched up
newspaper so more heat will be absorbed to keep a high temperature.
7. Once your solar oven is fully complete you will be able to start your experiment. The aim is to see
if your oven gets to rapid temperatures so you need to check your temperatures on a regular basis.
You will need to check at least every hour to see if your oven is a success!

The Oil And Gas Industry
When thinking about how all this oil and gas gets from the platforms in the gulf to land to be
produced, you will run across the phrase, "flow assurance." Flow assurance is what makes sure these
oils and gases get from point A to point B without any hesitations or problems. Its main purpose is to
prevent hydrates, clogged pipes, and wax depositions. So can the oilfield industry survive without
flow assurance, especially in deep water operations? By reading this, you will learn how important
flow assurance is in this industry, and what serious problems can happen because of the failure of
flow assurance.

Flow assurance is the most critical task during deep water production because of the high pressures
and low temperature involved. Now that we have ventured off further into deep water drilling, no
longer does pipe flow analysis mean, "pressure versus flow rate." When conditions are "wrong,"
hydrates, waxes, or asphaltenes form and come out of the well stream fluids, plugging up flowlines
and processing equipment. So, what are hydrates? Hydrates are crystalline, ice–like solids that form
when small gas molecules, such as methane, ethane, and propane, are trapped in hydrogen–bonded
water cages under high pressure and low temperature conditions. Hydrate nuclei form from the films
of water on the tubular walls. The crystallization of hydrates can result in formation of hydrate plugs
which can end up being hundreds of meters long. The formation of these hydrates can vary from
instantly to a few hours. If there is free water present, hydrates can form in the pipes. Natural gas
hydrates are crystals formed by water with small gas molecules and associated liquids in a ratio of
85 mol% water and 15 mol% hydrocarbons. Gas hydrates have been called "the burning ice." This is
due to the fact that gas hydrates are "host" water cages containing "guest" gas molecules. These
combustible gas molecules can be

Comparing Dundee University's Heat Energy Systems And...
Introduction
This report shows the differences and the similarities between Dundee University's heat energy
systems and those that are employed by Hillcrest Housing Association. The main technologies used
in the university are gas fired engines, whereas the Hillcrest building which has a biomass boiler. As
far as models of ownership are concerned, the University has established a wholly owned operating
company DUUSCo to undertake the Project. While, although owned by Hillcrest the biomass
system is operated and maintained under a 10–year agreement by Angus Biofuels who sell the
energy to Hillcrest. Finally, comparing the risks associated with security of energy delivery we can
say that they are similar. Even if the two heating systems are different, both of them had the same
goal, reducing the energy used and achieve low energy consumption. And move a step closer to
sustainable and zero carbon buildings. An explanation of "zero–carbon" meaning is given.
Technologies used in Hillcrest and Dundee University
Hillcrest Housing Association (Appendix A) building uses for heating, except for the orientation and
the big windows on the North and south, the air. Air is brought into the building through 5 trunk–
molded conduits climbing out of the grass to the once again of the building (Appendix G, 4). Low
controlled fans support the methodology. The air is drawn into a "maze" of 600mm solid pipes that
bolster into a block chamber which works on the same guideline as an issue –

A Brief Look at Geothermal Energy Essay
The power of electricity is available to anyone with a simple click of a button. The methods of
obtaining the energy used to develop that electricity are commonly debated topics. One of those
methods is using geothermal energy, or the Earth's naturally produced heat. There are plenty of
intriguing facts centered upon geothermal energy. For thousands of years, geothermal energy has
been used in some countries for heating and cooking ("Geothermal Energy Info" 2). These
underground systems being used contain water with teperatures that can rise above 200 degrees
Celsius (430 degrees Fahrenheit) ("How Geothermal Energy Works" 2). Italy used geothermal

These "hot spots" usually occur at thin spots in the Earth's crust or at tectonic plate boundaries
("How Geothermal Energy Works" 2). Water circulates naturally in these seismically active
locations due to the large number of earthquakes in the area. ("How Geothermal Energy Works" 2).
Four forms of producing geothermal energy are currently available: dry steam, wet steam, hot rocks,
and geopressured deposits (Savage 22). To gain access to these resources, cooled water is injected
down a well where it circulates through fractured rocks and heats up. Once hot, the water is sucked
back up to the surface through another to be further processed into energy ("Geothermal Energy" 2).
Dry steam sources are very practical for producing energy due to its very high temperature and its
ability to cause no corrosion to turbines and various types of other equipment involved in the
process (Savage 22). On the other hand, wet steam sources must be regularly maintained because
they do cause damage to the equipment if left unchecked. Despite this drawback, it is a very useful
way to generate energy (Savage 22). "Hot rocks are tantalizing geothermal sources, but water must
be introduced artificially to the dry heat source to produce steam or hot water" (Savage 22).
Geopressured deposits have been exploited for a very long time because they are generally hotter
than most underground water systems (Savage 22). Magma is, without a doubt,

Analysis Of Development Of Solar Architecture Essay
Analysis of development of solar architecture in China: How has modern architecture been
redefined by this and Could it be the key factor in build a non–renewable energy free generation?
Introduction
In the past century, our society had changed rapidly due to varieties of newly found awareness such
as the concept of global warming and shortage of our finite power supply. These awarenesses caused
us to adapt and develop new techniques in order to survive. One of the many things that had been
changed in our society were the architectures especially in the more developed countries such as
England ,America and China. As such, the concept of sustainability had "entered into the
consciousness of architects and became an essential concern in the discourse of architecture" (1).
With sustainability as priority in mind, architectural designs now focuses on how to increase the
reduction of non renewable energy usage by using the energy exacted from nature itself.
For this dissertation, the main objective is to fully analyse how the idea of using green energy as an
alternate source of energy had effect the architecture in China. Amongst the countless type of
sustainable architecture, I have chosen to analyse the Solar Architecture in China as the main focus
for this dissertation. In China, The concept of using solar energy as a direct power source had only
been acknowledge in the recent years yet , as of 2005, China had became the leading solar energy
pioneer in the world. So how

1) The sole plate of the steam iron:
This is usually the metal thick, triangular–shaped slab of iron that forms the base over which the
electric iron is built up. The sole plate is cast of molten aluminium. Some part of the mould has the
holes shaped in it which creates the holes that are essential in a steam iron. Heated metal is inserted
into a mould under pressure then cooled and then released. This cooled sole–plate is later on treated
in several ways where it's firstly polished then either it's: coated with a non–stick material, or
covered with another metal (usually stainless steel). To complete these processes, the sole plates are
put on a large automated carousel, which rotates through each step whereas to polish the plate, an
automated belt sander uses bands of abrasive to polish and buff the plate. An automated spray–
painting machine is used to apply the non–stick coating. After application, the sole plate is baked in
an automated industrial process.
On the other hand, to coat with another metal (stainless steel), the external metal cover is created by

Essay on The Energy Star Home
The Energy Star Home
The Energy Star label is awarded to products that promote energy–efficiency. New homes have been
included in the Energy Star Program. Energy Star products must be at least 30% more energy–
efficient than current regulations demand. The same energy requirements apply to the Energy Star
Home as well. Such areas on a home that are targeted for improvement include: framing, ducts,
windows, insulation, and HVAC. Although, the energy star program includes appliances and
electronics, when applying the program to a home, only structural improvements are taken into
consideration. It is possible for a home to receive an Energy Star Label but at the same time be filled
with non–energy star appliances. Older homes can ... Show more content on Helpwriting.net ...
New energy star homes will have a label on the breaker box stating that the home has undergone a
third party evaluation. This evaluation ensures that the home either meets or exceeds energy star
requirements. The Home Energy Rating System, or HERS, scoring is how a home is ranked based
on energy–efficiency. The HERS works on a 100 point system, with a score of 80 for a house that
meets the minimum requirements of the Model Energy Code. Each point on the HERS scale
corresponds to a 5% increase in efficiency meaning that a minimum score of 86 is needed for a
home to receive an energy star label.
There is another possibility for builders known as the Builder Option Packages, or BOPs. For the
purpose of BOPs, the US has been divided into 19 climate zones. Each climate zone has
construction specifications that include performance levels for the thermal envelope, insulation,
windows, orientation, HVAC systems, and water heating efficiency. A home built to BOP specs is
not rated by the HERS system but still is subject to third party verification. BOP homes either pass
or fail as energy star homes.
The first consideration when building an energy–efficient house is tight construction. There are
hundreds of holes that penetrate the outside of a house resulting from framing and holes drilled for
wiring, plumbing, and ducts. By framing the house more carefully and tightly, there will be fewer

Electricity Is Generated From The Energy
HYDROFUEL CELLS
Abstract: Electricity is generated from the energy; we get, by the burning of fossil fuels, where the
fuel can be stored and used when needed according to the immediate energy requirements. Hence it
is speaking to a concentrated and stable type of energy. On the opposite side, we have some irregular
types of energy, for example, wind, wave, tidal and sunlight based. These can 't be put away and
must be utilized according to accessibility; generally their energy possibilities are lost. For the usage
of these energy sources, there is a need to convert this energy into suitable forms for storage. For
this Hydrofuel Cells are one of the best way to create and store energy as they possess many positive
qualities such as renewable, environment friendly, readily available elements for electricity
generation etc. Here it is discussed about the working of Hydrofuel cells, advantages and
disadvantages and lots more. The paper also contributes the comparison of Hydrofuel cells with the

Entropy is somewhat clearly the primal reason for our vitality emergency: we are blazing fossil
powers we can 't supplant, while the supposed atomic arrangement will require more vitality to
develop and keep up than it can ever be relied upon to come back to us.
Entropy, Rifkin additionally contends, is for the most part in charge of not just social and monetary
issues clearly coming about because of the vitality emergency, additionally for issues felt much
sooner than fossil fills ran rare. Issues of scale, for occurrence: a wrongdoing rate duplicating
geometrically as urban areas increment in size. An educational system weakening subjectively, even
as it quantitatively develops.
Here entropy gets to be not a conspicuous, quickly obvious physical rule, but rather an illustration
for what happens when establishments develop so extensive that, as with some parts of the interstate
thruway framework, a bigger number of assets most be spent on upkeep than upon really doing
whatever they should do in any case. The weapons contest, the populace blast, and our present
malignancy scourge, Rifkin cases, are all entropy exemplified.
Maybe, to a degree, since some entropy is inescapable. Yet, the connection between the amount of
data our schools confer and the amount of vitality their physical upkeep exhausts is dubious, no
doubt. We may take the same assets and contract an individual coach for each tyke on low

Sun Solar Energy
How does the sun's energy affect water?
The sun is the star at the center of the solar system. The Sun is the primary source of energy. Solar
energy is light and heat from the sun. Solar energy is important to renewable energy. The diameter
of the sun is 1.39 million kilometers. The Sun's mass mostly contains hydrogen and helium.
The use of sunlight is to supply the needs of humans like energy is a primary source to survival on
earth. The sun's energy is able to feed animal need's. Only green plants are able to convert the
energy from the sun into fuel and food. Most of our food and fuel are made through the sun with a
process of photosynthesis.
In early experiments a man name Joseph Priestley study the rays of the sun's energy onto mercuric
oxide and collected gas that was making heat from the sun rays and the mercuric oxide. In 1954
there was a group named "Association for Applied Solar Energy" this group was made in Phoenix,
Arizona. This group publishes books about how students or people in general want to learn how the
sun's energy works. Most people go to this group for ideas to work on projects and other. The sun
energy could work in many different ways to the atmosphere or there's a purpose to why the sun
shines so bright.
The sun has many rays or like different levels of heat. The sun has three main regions; the sun's
interior, solar atmosphere, and the visible surface which is in the middle of the interior and the
