Scope
MTG.OBB coordinates TC/TG/TRG technical activities to help implement the recommendations from this MTG. This includes coordinating efforts in education, modeling, research, standards, marketing, advocacy, and fund raising within ASHRAE. Research project initiation as the sponsoring committee is included in the scope of this MTG.
Occupant behavior in buildings refers to occupants’ comfort preference, presence and movement, and interactions with building systems that have impact on performance (thermal, visual, acoustic, and IAQ) of buildings. The interactions include adjusting the thermostat settings, opening or closing windows, dimming or turning on/off lights, pulling up or down window blinds, switching on or off plug-loads, and consuming domestic hot water.
Objective/Impact
MTG.OBB sponsors and coordinates activities of related ASHRAE technical and standards committees to facilitate development of data, tools, technologies, and guidelines enabling integration of occupant behavior in the design, operation, and retrofit of new and existing commercial and residential buildings. The intent is that these products, focusing on the human dimension, may be used in the life cycle of buildings and potentially contribute to ASHRAE’s energy saving targets, by demonstrations of behavior-driven passive and active building designs and identification of energy saving opportunities from behavior measures. Within ASHRAE, the MTG coordinates activities to update related parts of ASHRAE Handbooks and Standards (particularly energy and indoor environmental calculations, standards 55, 62.1, 62.2, 90.1, 90.2 and 189.1), and to develop related education programs for buildings designers, operators and occupants. Outside of ASHRAE, the MTG monitors related activities (e.g. IEA EBC Annex 66, Annex 79) and represent ASHRAE interests where permitted to provide a conduit for related information transfer to ASHRAE members.
