DescriptionBuilding energy modeling (BEM) is a useful tool for identifying design strategies for new buildings and for implementing new energy conservation measures (ECMs) for existing buildings. While many energy conservation measures related to HVAC efficiency and electrical load have been researched, few ECMs relating to the envelope of the building have been studied. The purpose of this thesis is to measure the potential reduction in energy usage of Richard Weeks Hall in response to a variety of envelope ECMs. These ECMs include increasing the roof insulation value, increasing the exterior wall insulation value, incorporating a green roof and incorporating a green façade. The predicted reduction in energy consumption for the green roof and green façade were 10% each, while the predicted reduction in energy consumption for increasing the roof and wall insulation values were approximately 1-2% each. An energy model of Richard Weeks Hall was created using the energy modeling program eQuest. The control (baseline/datum) model was created using the actual construction values and mechanical information of the building. The experimental models simulate a green roof, green façade, and rooves/walls with higher insulation values. Increasing the insulation values reduced the energy consumption of Richard Weeks Hall by approximately .5%. The green roof and green façade reduced the energy consumption of the building by 5.2% and 5.1% respectively. While every ECM resulted in a lower reduction in energy usage than predicted, the reduction from the green roof and green façade is still significant for a university building. Compared to other envelope ECMs, the incorporation of a green roof and green façade is a great opportunity for energy savings in existing and new buidings.
