摘要

This paper summarizes the methodology and main results of two recently publishedrnTechnical Support Documents. These reports explore the feasibility of designing generalrnmerchandise and grocery stores that use half the energy of a minimally code-compliant building,rnas measured on a whole-building basis.rnWe used an optimization algorithm to trace out a minimum cost curve and identifyrndesigns that satisfy the 50% energy savings goal. We started from baseline building energy usernand progressed to more energy-efficient designs by sequentially adding energy design measuresrn(EDMs).rnCertain EDMs figured prominently in reaching the 50% energy savings goal for bothrnbuilding types: (1) reduced lighting power density; (2) optimized area fraction and constructionrnof view glass or skylights, or both, as part of a daylighting system tuned to 46.5 fc (500 lux); (3)rnreduced infiltration with a main entrance vestibule or an envelope air barrier, or both; and (4)rnenergy recovery ventilators, especially in humid and cold climates. In grocery stores, the mostrneffective EDM, which was chosen for all climates, was replacing baseline medium-temperaturernrefrigerated cases with high-efficiency models that have doors.rnAdditional analyses presented here include specific examples of how 50% savings werernachieved in climate zones 1A and 6A with EDM packages; a comparison of the costrneffectiveness of different EDMs; and the generation and subsequent comparison of multiplernsolution sets that all satisfy the 50% energy savings goal.
