This presentation discusses architect-engineer services for the master planning and design of a central utility facility (CUF) over a 10-year development period. It covers net zero energy definitions, case studies of net zero energy buildings including a university lab and air force hangar, strategies for achieving net zero energy through integrated design and renewable energy options, and lessons learned.
amount of energy used is equal to amount of renewable energy created on the site
reduce carbon emissions & reduce dependence on fossil fuels
Buildings that produce a surplus of energy over the year are called “Energy Surplus Buildings”
During the last 20 years more than 200 reputable projects claiming net zero energy balance have been realized all over the world.
NZEB buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Traditional buildings consume 40% of the total fossil fuel energy in all over the world and are significant contributors of greenhouse gases.
Passive solar design is an important feature in the design of this building.The planning and orientation of spaces and building blocks ensures glare free daylight in all regularly occupied spaces. All the linear blocks are oriented in the East-West direction with shorter facades facing the sun.
Most of the south west facing walls are kept blank in order to protect the building from the harsh south west solar radiations. Where the south west walls have openings, they are protected by means of pergolas or projecting balconies. The east, west and south facades of the building have minimum glazing.

Join us as Finegold Alexander presents the study for the Lowell Trial Court, a 250,000 SF state courthouse designated by Gov. Patrick’s Zero Net Energy Building Task Force as one of three public demonstration projects addressing the challenge of designing public buildings to high sustainability standards.
The engineering components of the study involved proposals for energy reduction and on-site production, investigated through a multitude of computer models and cost-to-benefits charts and analysis. Architecture and architects must change. Architectural form is a critical element in achieving any sustainable goals, including zero net energy. This session will look at the Lowell Trial Court design process and the iterative schemes the team produced. We will discuss building massing, orientation, urban context and all the elements we always address in every project. Now we find our attitudes toward these traditional design criteria are influenced by the integration of sustainable design. Design for zero net energy caused this team to think and collaborate differently with consultants, client and user groups.

The idea of Energy Efficient design is
to modulate the conditions such that they
are always within or as close as possible to
comfort zone.Modulations introduced by the
landscape,built form,envelope,materials and
other control measures bring the conditions
within the range throughout twenty four hours
cycle.
This is goal of Energy Efficient Architecture
Buildings, as they are designed and used today, contribute to serious environmental and economical problems because of excessive consumption of energy and other natural resources. The close connection between energy use in buildings and environmental damage arises because energy-intensive and monetarily expensive solutions sought to construct a building and meet its demands for heating, cooling, ventilation, and lighting cause severe depletion of invaluable environmental resources
Energy resource efficiency in new constructions
can be effected by adopting an
Integrated Approach To Building Design.
Case Studies of Sustainable Office buildings, these both case studies are based on sustainable features adopted inorder to make the entire structure energy efficient as well as encourage work environment within the premises, i hope it helps out students of architecture, engineering backgrounds!!!...
Intelligent buildings are buildings that through their physical design and IT installations are responsive, flexible and adaptive to changing needs from its users and the organizations that inhabit the building during its life time.

Building simulation is the process of using a computer to build a virtual replica of a building.
The building is built from its component parts on a computer and a simulation is performed by taking that building through the weather conditions of an entire year.
In a way, building simulation is a way to quantitatively predict the future and thus has considerable value.
Building simulation is commonly divided into two categories:
Load Design,
Energy-Analysis.
The common phrase for building simulation when energy is involved is Energy-Simulation.

A Net Zero Energy Building (NZEB) produces as much energy as it uses over the course of a year; legislation and technology are combining to create a future where buildings actually contribute energy to the grid.
Zero energy buildings economical and environmental aspectsMD ASIF AKBARI
A net zero energy building can be defined as a building which generates as much energy through renewable sources as much as it consumes from the Grid. To achieve this purpose, Renewable Energy Sources like Solar Energy, Wind Energy, Biogas Energy and Geo thermal energy have to be harnessed properly so that the energy borrowed from the Grid can be replenished by these sources. In this paper, an attempt has been made to compare the economic and environmental aspects of energy generated from these resources and to tell us which of the above mentioned non renewable energy resource is the best suited based on the parameters of economic and environmental feasibility.

Is it possible to maintain the standard of living we've come accustomed to and find a balance within the limits of the capacity of our ecological systems? The answer, of course, is yes but not without doing things smarter and possibly differently.
We will define what net zero waste is, discuss strategies and approaches to achieving it, metrics available and look at some best practices in the industry as this concept is emerging.

Webinar - Nearly Zero-Energy Buildings and Offsite RenewablesLeonardo ENERGY
The energy performance of buildings is key for reaching the European Union’s very ambitious climate targets. “Nearly zero energy building (nZEB)” is the term for a building standard that complies with this ambition.
Living in 2013 we have 8 years to go until every single Member State will have to build every new building as nearly zero energy building, and even only 6 years to go for nearly zero energy public buildings.
This webinar goes through some definitions of nZEB, including the concepts “on-site” and “nearby” electricity, introducing a debate around the role of “off-site” electricity in nZEB. An analysis will be done on how to determine the renewable share, balancing periods, suitable metering schemes, tariff design, ownership schemes of electricity generation, standardisation, monitoring and verification.
Still a lot of research needs to be done for developing a consistent European approach for nZEB. This webinar (and related background paper) aims to make a contribution to getting the answers in time.

A presentation by Joe Ventresca of Max Green
Presented at the Columbus Green Building Forum's 2011 Green Building EXPO
Building owners have more questions and requests on how to integrate renewable power into their buildings. And as the Smart Grid evolves, integration of renewable energy sources is increasing. Possible renewable power technologies include solar, wind, geothermal, and biomass. As the technologies that support increasing use of renewable energy mature, the codes and standards that define their use, interconnection, and interoperability with the grid must keep pace with them. Engineers involved with integrating renewable power into buildings must be aware of the applicable energy codes and standards and how to properly implement them into the building design. They must also evaluate the design objectives, materials, systems, and construction from all perspectives. It’s critical for designers to assess the design for cost, quality of life, expansion capabilities, efficiencies, impact on environment, creativity, and productivity.
CEE and Seventhwave lead a rapid-fire discussion of innovative tech and program approaches, and the most meaningful recent research findings for utility representatives, efficiency program implementers, and both residential and commercial field experts.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

degrees
10. Net Zero Energy Definition
Type Description
Net Zero Site Energy The boundary is the site and
the energy is measured
annually at the utility meters
Net Zero Source Energy The energy is valued at its
point of extraction (e.g. the
wellhead or the coal mine)
Net Zero Energy Cost The credits received on
exported energy equals the
amount of annual energy bills
from utilities
Net Zero Energy Emissions The emissions from fossil fuel
energy use are offset by
renewable energy fed into the
grid on an annual basis
13. Net Zero Energy Definition
• Source versus site energy
• On-site combustion versus all electrical
• Treatment of off-site renewable energy
generation and carbon offsets
• Campus setting versus treatment of individual
buildings
• Treatment of embodied energy
• Division of responsibilities between owners,
tenants and utilities
17. Green Design Features
• Mixed mode ventilation with solar chimney
• Rainwater harvesting
• Solar PV and thermal
• Ground source heat pumps
• Radiant underfloor heating
and cooling
• Energy recovery ventilation
• Daylighting
27. C-130J Fuels Maintenance Hangar
• Net zero energy design definition
»Includes plug/process loads
»Based on site energy, gas use is okay if it is offset on a
per Btu basis
»Transportation energy use not accounted for
• Challenges
»FMH require high exhaust and make-up air flow rates
»90.1-2007 PRM requires an artificial cooling system in
the hangar (this has changed thankfully)
»Hangar infiltration is a big concern in heating season

Sustainable design
is most effective
when applied at the
earliest stages of
design
The conceptual design
process is a
collaboration of several
disciplines that
effectively integrates all
aspects of site planning,
building design,
construction, operations
and maintenance
A Sustainability
(Eco) Charrette is an
intensive workshop in
which stakeholders
and experts come
together to address
project sustainability
issues
The Charrette should
result in unified
sustainability, design
and construction goals
for everyone to work
toward
40. A Sense of Place
• Integrate the building with its surroundings
• Apply the most economical options to achieve the desired result
(e.g. don’t install a wind turbine to look green that won’t be
running most of the time!)
• Passive solar design should not be skipped over but should be
balanced with functionality and aesthetics
42. NZE Design for Passive Measures
• There is an economical limit to insulation levels
(diminishing returns)
• Limiting solar heat gain through high
performance glazing or solar shading is
paramount (especially in Texas!)
• If your local climate is amenable to natural
ventilation, the architectural design should be
accomodating to it, we have the tools now!
• Good daylight design is an iterative process and
proper modeling time should be allotted
43. NZE Design for HVAC
• Variable refrigerant flow (VRF) – very cost-
effective now compared to traditional systems
• Geothermal
• Radiant heating/cooling
• Displacement ventilation (and sometimes UFAD)
• Energy recovery ventilation – decouple space
conditioning from ventilation load to improve
effectiveness and control
• Use LED lighting where you can and use lighting
controls wherever they will help, e.g. occupancy
and daylight sensing
44. NZE Design for Renewables
• Solar PV – Very “plug-and-play” but account for placement and
orientation, PPA is a popular vehicle for large installations, default
NZE equalizer
• Solar thermal – EISA 2007 requirement for federal buildings, usually a
no-brainer for NZE
• Transpired solar collectors – excellent for areas with simultaneous
sunshine and heating hours
• Biomass – difficult to beat as a high quality heat source
• Wind – often very cost-effective but hub height must be high enough,
very visible though
• Offshore wind and wave/current energy – good potential for coastal
areas
45. NZE for Designers
• Form follows function instead of function following
form, NZE is a performance target and deviating
from this principle can torpedo an otherwise
successful approach
• Integrated, coordinated approach: disciplines
should not work in isolation, design changes can
have effects all the way down the line
• Model energy use early and often
• Design with a “systems mentality”; like in nature all
building systems are somehow connected, e.g.
DHW on geothermal system, selection of material
reflectances affects daylighting, etc.
46. NZE for Building Users/Owners
• Plug/process loads become 40% or higher of overall
building energy use for NZE designs
• Occupant behavior’s effect on energy use becomes very
significant, behavioral change is often necessary
• Emphasis on flexibility rather than recipe approach: Might
have to revisit existing design standards and decisions in
order to achieve goal of NZE
• Suggest energy sub-metering, EMS and dash-boarding to
complete energy information feedback loop
• Expect to spend more time on conceptual design phases
47. Cost of Net Zero Energy
• Cost premium anywhere between 5% up to 25%
or even higher
• Emphasis on delivering NZE economically
• Rigorous life cycle costing is crucial
• Implementing passive energy measures can
often down-size HVAC equipment enough to
save significant costs
• Spend time on careful cost estimation at various
decision points: rules of thumb and $/sf
estimates don’t work very well for NZE
48. Net Zero Energy Economics
• How effective is the energy reduction measure compared
to PV?
• For the same amount of kWh saved from an ECM, how
does it compare to the cost of PV to generate the same
amount of kWh?
• This is often the cost inflection point between energy
efficiency and renewable energy
