Effects of occupant issues on the energy performance of two existing passive commercial buildings
Abstract Results are presented from a study of occupant related energy issues in two buildings from the U.S. Department of Energy's Passive Non-Residential Experimental Buildings Program. This study is part of a broad effort to evaluate energy, functional, and economic performance of all twenty buildings in the program based on onsite observations and physical data. The work reported here supplements basic building energy performance data with observations and responses of occupants of the buildings, highlighting aspects of practical performance of passive systems. Energy analyses were performed to examine more comprehensively the sensitivity of building performance to occupant issues. Occupant analyses of all buildings in the program led to specific issues' being addressed: (a) the effect of mass levels and distribution on peak and seasonal energy performance and building response; (b) the intereaction of such mass effects with thermostat setback strategies; (c) the energy effect of acoustical treatment of surfaces that play a role in passive thermal distribution; and (d) the effect of occupant management of shading devices on building energy performance. Results of this study provide quantitative information on energy impacts of building modifications that affect or are affected by occupant satisfaction and interaction with passive systems in the two buildings examined. Passive strategies are shown to affect the occupants' environment as well as the buildings' energy use. Two distinct techniques for utilizing thermal mass in passive commercial buildings are identified and characterized. Changes to thermostat control strategy and solar aperture shading are shown to be capable of causing significant changes in building energy performance and occupant comfort. Effective acoustic treatments which can be designed to have only marginal effects on energy requirements and occupant comfort are described.
