These seminars made possible with funding from Uponor.


Seminar #1 Human Factors in HVAC: Thermal Comfort and Indoor Air Quality for Lifetime Housing, Thursday, Mar. 6th, 1:30–2:45 pm, Portia Room. See citation list.

The expression, "long term care" rarely invokes thoughts of a non-institutional healthcare facility, such as one's own home; toss in phrases such as, "Aging in Place" or "Universal Design" and most people think of devices or aids for daily living and wheel chair accessibility. Very few housing programs consider the indoor environmental ergonomics needed for a maturing population. This presentation will prepare designers, manufacturers and trades people to consider the human factors in HVAC for a growing population of elders.

1. Discover how age related physical and cognitive challenges conflict with “modern” HVAC systems.
2. Discover how age related physical and cognitive challenges fit in with naturally ventilated buildings and adaptability.
3. Discover how age related physical and cognitive challenges affect maintenance of HVAC systems.
4. Learn what to consider and advise client s for HVAC equipment and systems in Lifetime Housing.

Seminar #2, The Interaction and Connection between Buildings, HVAC System, and Indoor Environmental Quality, Thursday, Mar 6th, 3:15–4:30 pm. Aralia/Marula Rooms

In reviewing literature representing thermal comfort, indoor air quality, building performance and HVAC, it is apparent that a central temperature of 77.5F+/- 22.5F (25C+/- 12.5C ) is common to the highest performing buildings delivering the highest indoor environmental quality. This range captures temperatures of the human body whilst 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.

1. Discuss building performance, HVAC exchanger surface areas and temperatures.
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.
