The influence of passive features on building energy demands for space heating and cooling

Aylin Ozkan, Ted Kesik, William O’Brien

Abstract: This paper explores the development of a methodology to assess the relative impact of passive measures on building system performance. Over the life cycle of a building, its use and occupancy can undergo significant changes when the building is re-purposed. Initial energy modeling assumptions about active systems that respond to occupancy and operating schedules may no longer apply. The most persistent attributes are the passive features of the building such as the building form and solar orientation, the overall effective U-value of the enclosure, fenestration and fixed shading devices, and its thermal mass and airtightness. Parametric simulations of the energy performance of multi-unit residential buildings form the basis of this paper and results are ranked to indicate the relative significance of various passive features to the peak and annual energy demands for space heating and cooling.
