India Energy Efficiency Building Codes
AEC's objective was to reduce the energy use in buildings by development and implementation of an energy efficiency building code (EEBC). Compared to buildings in countries with established building energy codes, the average energy use in commercial buildings in India was significantly higher. The project team worked to develop building energy codes for the six climatic zones (cold & sunny, cold & cloudy, hot & dry, warm & humid, moderate, and composite).

Australia Energy Code - Research and Development
AEC was selected to write a draft nonresidential building energy efficiency standard for the Australian government. The work included developing energy models for nine Australian climates, identifying energy efficiency measures appropriate for the various climates and economic conditions, performing life-cycle cost analyses to establish the appropriate level of energy efficiency, and performing an impact analysis that quantified the energy savings and environmental benefits that would result from implementation of the code. Approximately 4,000 DOE-2 computer simulations were performed for this analysis.

Philippines Energy Efficiency Policy Analysis
AEC analyzed the energy savings potential of implementing commercial energy codes and expanded appliance standards for the Philippines. Using typical buildings, AEC estimated the changes that would be required if an energy code were in place. Three codes were evaluated, ASHRAE Standard 90.1-1999, the Hawaii code and the Guam code. AEC staff estimated the potential for energy savings and demand reduction from energy code and appliance standard improvements Data was collected on anticipated construction activity and the savings were projected to all building types. The state of Hawaii has received funding for a follow-up study.

Hong Kong Energy Code
AEC worked with a local engineering firm to develop building envelop requirements for Hong Kong. AEC developed DOE-2 computer models to determine the relative cooling impact of wall insulation, wall color and glazing characteristics and other measures. This data was used in a regression analysis to develop a recommended code based on the Overall Thermal Transfer Value (OTTV). This metric is used in many codes in Asean countries. AEC also made recommendations for future energy studies needed for development of a comprehensive building energy code.

Palau Energy Code
AEC developed an Energy Code for the Republic of Palau. It is based on ASHRAE Standard 90.1-based Energy Code developed for the Territories of Guam and American Samoa served as a model.
