Welcome to the homepage of the ASHRAE Technical Group 1.
TG-1. Exergy Analysis for Sustainable Buildings is
concerned with all exergy aspects of energy and power utilization of systems
and equipment for comfort and service, assessment of their impact on the
environment, and development of analysis techniques, methodologies and
solution for environmentally safer, sustainable low-exergy buildings.
Existing building HVAC and plumbing systems and equipment
have already achieved high thermal efficiencies as defined by the first law of
thermodynamics. According to the second law of thermodynamics however, there is
a need to increase currently low exergy efficiencies primarily because existing
systems and buildings demand high-exergy sources. In this respect, IEA Annex 37
recognized exergy-efficient buildings and development of low-exergy systems and
equipment to be the most important need for sustainable development
and environment. Currently, there is a lack of information about the importance
and relevance of the subject matter, in particular for green buildings and for
sustainable development. This TG will raise the exergy awareness among engineers
and provide the fundamental information and tools for the implementation of
exergy efficient designs and development of consistent exergy related
methodologies. This TG will establish a robust road map for a comprehensive set
of scientific and technical steps for an environmentally safer building
technology and HVAC systems and facilitate the new ASHRAE theme of Engineering
for Sustainability.
