Energy modeling is a well-established field widely used in estimating the energy consumption of new or existing buildings. This course will introduce students to the latest versions of commonly used freeware in the field: Retscreen, EQuest, and Hot2000. This is a software intensive program that requires students to model the energy consumptions of new and existing buildings. In addition, the effects of energy conservation measures (ECM)introduced into the models will be examined. Students will have an exposure to alternative energy sources via the Retscreen models. Economics of ECM and renewable energy systems will also be covered.
