The Interaction and Connection between Buildings, HVAC, and
Indoor Environmental Quality

This program is eligible for 1 AIA Learning Unit
In reviewing literature representing thermal comfort, indoor air
quality, building performance and HVAC, it is apparent that a
central temperature of 77.5°F+/- 22.5°F (25°C+/- 12.5°C ) is
common to the highest performing buildings delivering the
highest indoor environmental quality. This range captures
temperatures of the human body enabling peak efficiency from
mechanical systems. Within this zone there are improvements to
thermal efficacy, a reduction in entropy and a facilitation of
exergy efficiency with renewable resources; and a reduced
breakdown of building materials, and improved perceptions of
thermal comfort and air quality. A new graph will be presented
to show how elements within indoor environmental quality (IEQ)
and the building and HVAC technologies that control or otherwise
affect it are interactive and connected.
This webinar will:
1. Discuss building performance, HVAC exchanger surface areas
2. Explain the relationship between, energy, exergy, efficiency,
entropy and efficacy.
3. Understand the concepts around low temperature heating and
high temperature cooling.
4. Explain the sustainability risk to society when conserving
energy is the exclusive goal.
