Optimization of Energy Efficiency and Conservation in Green Building Design U...Totok R Biyanto
The development of green building has been growing in terms of both design and quality. The development of green building bariered by the issue of expensive investment. Actually, green building can reduce energy usage in the building especially in utilization of cooling system. External load plays as major role of reduction in the use of the cooling system. External load is affected by type of wall sheathing, glass and roof. The proper selection of wall, type of glass and roof material are very important to reduce external load. Hence, the optimization of energy efficiency and conservation in green building design is required. Since this optimization consist of integer and non-linear equations, this problem fall into Mixed-Integer-Non-Linear-Programming (MINLP) that required global optimization technique such as stochastic optimization algorithms. In this paper the optimized variables i.e. type of glass and roof were chosen using Duelist, Killer-Whale and Rain-Water Algorithms to obtain the optimum energy and considering the minimal investment. The optimization results exhibited the single glass Planibel-G with the 3.2 mm thickness and glasswool insulation provided maximum ROI of 36.8486%, EUI reduction of 54 kWh/m2·year, CO2 emission reduction of 486.8971 tons/year and reduce investment of 4,078,905,465 IDR.

Energy and Indoor Air Quality Impacts of DOAS Retrofits in Small Commercial B...RDH Building Science
Heating, ventilating and air-conditioning (HVAC) typically accounts for 30% to 50% of commercial building energy use. Small commercial buildings often use oversized and inefficient rooftop air handling units (RTUs) to provide both air conditioning and ventilation. A conversion strategy to reduce energy
consumption is the installation of a very high efficiency dedicated outdoor air system (DOAS) to provide ventilation with a separate heat pump system to provide heating and cooling. Decoupling the heating and cooling from ventilation allows for improved energy efficiency and control of space conditions. Upgrades to mechanical systems can also improve the indoor air quality (IAQ) and comfort through control of carbon dioxide (CO2) concentrations, dry bulb temperature, and relative humidity (RH).
A pilot study of eight buildings was conducted to investigate the potential benefits of replacing existing RTUs with high efficiency heat recovery ventilators (HRVs) and air source heat pumps in the Pacific Northwest. This report contains results for a subset of seven buildings for which data is available. The
building energy use before and after the conversion was determined using utility data, energy modeling and monitoring. Indoor environmental conditions were measured at hourly intervals for up to one year postconversion using CO2, temperature, and RH sensors. The data was analyzed to determine changes in energy use and IAQ before and after the conversion.
This paper presents the pilot building results pre- and post-conversion. While several factors need to be in place to ensure optimal performance and cost effectiveness, the pilot shows that replacing RTUs with DOAS systems in existing commercial buildings can both reduce energy use as well as improve indoor environmental conditions. This conversion type is viable for a wide variety of building types and scale-up of the retrofits has the potential to significantly improve a previously underserved segment of the building stock.

Trichogramma spp. is an efficient egg parasitoids that potentially assist to manage the insect-pests from the field condition by parasiting the host eggs. To mass culture this egg parasitoids effectively, we need to culture another stored grain pest- Rice Meal Moth (Corcyra Cephalonica). After rearing this pest, the eggs of Corcyra will carry the potential Trichogramma spp., which is an Hymenopteran Wasp. The detailed Methodologies of rearing both Corcyra Cephalonica and Trichogramma spp. have described on this ppt.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

BREEAM Assessment
» 10 Sections within the overall assessment
» Only 1 section relates to Energy
» Of this section maximum score is 35 yet only 15 relate to CO2 reduction
» Points for Bat Boxes, Wildflower meadows, Consultation strategy etc
» Experience of Very Good rated building using more energy than Victorian Buildings
Display Energy Certificate (DEC)
» From the 1st January 2009, public bodies occupying buildings over 1,000m2 are
required to exhibit a DEC
» The DEC is based on the measured energy use, where the actual energy consumed in
the building is compared to a benchmark for similar buildings
» DEC “A” Rating = CO2 emissions 75% less than the benchmark building
» Up to Feb 2010 only 13 out of 3,230 offices certified achieved a rating of A (0.4%)

Project Aims
Sustainability Aims
• Display energy Certificates (DEC) are based upon the actual energy
usage of the building and all public buildings above 1000m2 require one
• Aim is a DEC “A” Rating = CO2 emissions 75% less than the
benchmark building
• For a general office building the benchmark CO2 emissions figure is
75.1 kgCO2
• DEC “A” Rating = < 18.775 kgCO2

Reducing Energy Use = Less Renewables Required
• Use passive measures to reduce the energy consumption of the
building. Improve insulation & air-tightness, utilise daylight & natural
ventilation whenever possible.
• Use high efficiency, low energy systems and equipment. Variable
speed pumps and fans etc. Recover waste heat off IT servers
• Finally add in renewable energy sources to offset energy use.
7. Bath and North East Somerset – The place to live, work and visit
Passive Design
• Building orientation to maximise daylight and
minimise solar gain
• Glazing on North and South elevation,
shading on East and West
• Building height and floor layout designed to allow
fresh air to move freely essential for natural
ventilation
• Airtightness and levels of insulation
8. Bath and North East Somerset – The place to live, work and visit
Ventilation
• Natural ventilation avoids large fans and ductwork
• Healthier internal environment
• 50% of the energy of A/C building
Lighting (30% of the building energy use)
• Maximise daylighht so this is adequate for 70% of normal working day
• Low energy light fittings
• Simple local control
Heating / Cooling
• High levels of air tightness (Use of CLT frame solution)
• High levels of insulation
• Use recovered heat from IT servers
• Building orientation, solar controlled glazing and thermal mass
9. Bath and North East Somerset – The place to live, work and visit
Ventilation
• It is a general rule that the energy use of a naturally ventilated building should be around
half that of an equivalent air-conditioned building.

Thermal Comfort
• Thermal mass is required to regulate the building temperature peaks.
• For the thermal mass material to absorb heat it needs to be cooler than the room air in the
day and for it to release heat it needs to be hotter than the room air at night.
• Exposed concrete soffits are generally the best form of thermal mass. Heat rises and so is
best absorbed at high level, the ceiling can be cooled to a lower temperature than the floor
and provide more effective radiant cooling.

Carbon Assessment
• Heating & HW: 38kWh/m2/yr = 7.54kgCO2/m2
• Electrical Base load: 14kWh/m2/yr = 7.23kgCO2/m2
• IT & Small Power: 41kWh/m2/yr = 21.2kgCO2/m2
• Emissions excess of 17.22kgCO2/m2 above DEC “A” Rating.
• Total CO2 savings required is 113,150 kgCO2.
• Eliminating the Heating & HW load and Electrical Base Load will not provide
the necessary CO2 savings.
• The IT and Small Power load has to be addressed.
13. Bath and North East Somerset – The place to live, work and visit
ICT Strategy
• ICT currently accounts for an estimated 59% of the building CO2
emissions.
• Reducing this load is the top priority in order to achieve a DEC “A”
Rating.
Thin Client
• Software, data, and CPU power resides on a network server rather than
on the client computer. Studies have shown a 50% decrease in power
consumption.
•Opportunity to recover heat from main servers to act as a heating source
for the building
•Each desktop devices reduced its power consumption by 90% compared
to a PC
