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
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
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
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.
