integrated design program has
over 2100 slides illustrating architectural, interior design
and HVAC engineering principles which contribute to
indoor environmental quality and
energy allocation for
conditioning the occupants and building.
The following course materials on IAQ
theory are samples from the lecture and based on a Steven Covey principle of "Begin
with the End in Mind". They are a very small but important sample of the Covey
principle and are provided here to give you an idea of what
kind of materials we'll be discussing during the program.
The course is also registered with AIA and participants can
earn up to 21 Learning Units.

There are two absolutes in IAQ, the first says, just
because you can't prove something doesn't exists doesn't
mean its not there...this is part and parcel of
Principle" which says in the absence of solid data
one should proceed with caution. It also implies that
you should not draw conclusive conclusions from any
investigation without comprehensive research and since
this is not practical in all but the most detailed
studies - what you can expect is generalization unless
proven otherwise. As with all our descriptions in these
sample slides - the discussion is much deeper but you'll
have to come to class for that broader talk.
This is the second absolute...why can someone smoke their whole life and then die from
natural causes while another will develop lung cancer at
an early age? There is so much we don't don't know about
epigentics but one thing we do know is some people
are bullet proof and others not so much. The environment
is full of triggers from allergens to pathogens and
sometimes for some people these initiate a physical and
psychological response that may allude others.
Figure 3: Our purpose at
healthyheating.com is to
integrate the knowledge between the health and
building scientists. We're also very clear that people
in the building world shouldn't pretend to be healthcare
workers likewise we don't expect doctors to be building
experts. We spend some time drawing the line and guiding
our students what is acceptable IAQ practice as it
relates to buildings and what to avoid so they don't
cross the line into the domain of medicine.
Figure 4: Above is how we see the
circle of knowledge and how we express that people
can be experts in one or perhaps a few areas but it
would take some extraordinary individual to have all the
knowledge. It's important to know your skills and
limitations and this is something we teach in the
Figure 5: This is a lesson for those who
air filtration is the only solution to IAQ problems.
Lets just say if the pollutant is on the conveyor belt
it can be filtered out...but many IAQ problems are not
airborne problems and have to be solved without
Figure 6: One of my favourite lectures
Dr. Green's TED talk on microbes in the environment.
She has a wonderful animation of the HVAC system and its
distribution capabilities for delivery air which can
include a plethora of microbes - some good and some bad.
Its well worth watching if you have an IAQ interest.
Figure 7: ASHRAE have been updating their
position documents on indoor environmental quality
concerns. These contain excellent information and are public
documents - we recommend you read them.
Figure 8: In the world of building
science, moisture is the number one problem. Too little
or too much and you'll find environmental challenges.
Working with our colleagues from Science Photo Library
we have acquired several high resolution
SEM images of common moisture related IAQ concerns
and discuss them during the program.
Figure 9: Our job in the world of
indoor climate engineering and building sciences is to
prevent the occupants from entering this hierarchy of
medical issues. Whether its asbestos, radon or carbon
monoxide - most IAQ concerns related to buildings are
preventable. At the end of the day
it's about being
proactive at the beginning of the design stage rather
than reacting to failed designs. A key message for our
Figure 10: The above slide is self
explanatory when it comes to IAQ. As a side bar in
reality - building suppliers, trades people and
contractors are not required to study the effects of
their finished product on human physiology and
psychology; and yet it will be the sensory systems from a real live human being that will be
the final judge. As it is today, the building industry
is judged by how it assembles parts, not necessarily how those parts
affect the health of the environment and by connection
the health of the occupants. In part this is due to our
culture of leaning naively on building codes for
"protection". Occupants of commercial buildings and home
owners need to
understand what it means to have a
built to code structure and why better building
protocols such as LEED™ or CHMC EQuilibrium™ or Energy Star Breathe Easy programs
worth adopting. It's for these reasons and many others
we believe building suppliers, trades people,
interior designers and
architects need to take a
basic course in human anatomy and physiology as it
relates to the indoor environment.
So there you have it, a few sample slides
from our IAQ theory lecturer...just a hors d'oeu·vre
from our library of over 2100 slides addressing a small
but important element of integrated design and radiant
based HVAC systems. In the
program we will get into this and a whole lot
more? How much more? Well just follow the links to the
other parts of our website and you’ll get a feel for the
scope of materials that we’ll be covering.
See you soon.
