Click on the below for more information on each task group.

Scope

MTG.ACR will coordinate TC/TG/TRG/SSPC technical activities to help evaluate the technical basis and adoption of airflow rate specifications in terms of Air Change Rate (ACR) or Air Changes per Hour (ACH) for spaces such as cleanrooms, laboratories, patient rooms, operating rooms, and other similar spaces. Responsibilities include the development of research projects, development and presentation of technical programs for all types of spaces which currently require ACR specifications, and a special publication detailing aspects of the ACR philosophy and practice. The work of this MTG will potentially impact design guidelines, ASHRAE Handbook, and related ASHRAE standards. This MTG intends to involve other national and international groups and organizations in these efforts.

Objective/Impact

Also note this group would not be limited to ventilation and infiltration studies as in the scope of TC4.3. Activities of this group would help in optimizing the use of ASHRAE resources including ASHRAE research funds by avoiding duplicate efforts among different TCs. Findings of the research and literature review will be disseminated through special publications, ASHRAE Handbooks, ASHRAE conferences and other special conferences on the subject. The outcome of these efforts will be communicated to ASHRAE standards committees, regulatory authorities, and other similar organizations to facilitate any modifications in their codes and standards.

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.
