"Negawatt" is a theoretical unit of power representing an amount of energy (measured in watts) saved. The energy saved is a direct result of energy conservation, increased efficiency, or demand response. Unlocking the "negawatt" rests on our ability to quantify and improve the performance of the building stock over time. However, building stock energy models, particularly those accounting for both physical formulation and social behaviors of the underlying buildings, are still in their infancy. This book was written as a Ph.D. dissertation that strives to more thoroughly examine how buildings...
