The core issues to be considered when attempting to make green buildng decisions
are set out below. We have devised a simple “reality check” test
that can be applied to every decision when renovating. Our reality check will
take the mystery out of green renovation and help you experience a smoother
process in which the interrelationship between the systems in your house, and
the environmental impact of your decisions, will reveal themselves to you. The
reality check is a simple set of questions to guide your decision making
process; ask yourself each of these questions before you make a final decision
on materials, products and systems in your home, and remember you may also need
to apply them to the other systems that are impacted by the decision at hand:
Energy Consumption
How does it affect my energy consumption? Does it reduce energy consumption
and thus the burning of fossil fuels?
Water
How does it affect the consumption of potable water? Does it save potable water
and/or reduce waste water from entering the sewer system?
Garbage
How does it affect demolition debris? Does it keep to a minimum the addition
of unwanted non-recyclable solid waste being added to our burgeoning landfills?
Energy Generation Does
it create energy (electricity through solar or wind power, produce hot water)?
Indoor Air Quality
How does it affect indoor air quality? Does it improve indoor air quality
and healthy living?
Sustainability
Does it use sustainable or recycled products and materials?
Natural
Environment How
does it impact on the overall natural environment? Does it improve the environment
by, for example, reducing or eliminating air pollution, add greenery and the
like?
A green home is a well designed and well constructed building,
built to maximize energy efficiency, healthy indoor air quality and have a low
impact on the natural environment. To that end, many of the decisions that need
to be made to achieve a well designed and well constructed building are not
glamorous – for example increasing insulation and filling cracks and holes
to prevent air seepage and radiation of heat through the walls; not over-sizing
a heating system (thus saving energy) b/c the professional who designs/sizes
the heating system has taken into account the heat loss savings from such non-glamorous
things as additional insulation, new windows, passive solar effects and the
like; planting for shade with drought-resistant trees. We need to reject the
idea that, to be “green” means to be different or special; reject
the idea that common, ordinary products like insulation, which clearly offer
environmental benefits (but watch those
VOCs,
see our Article Indoor
Air Quality -- Identifying Sources and Making Renovation Choices that Eliminate
Contamination) are to be discounted or overlooked, because that kind
of thinking furthers the erroneous view that homeowers must find sexy schemes
and products, which translates into “spend more money”. One of the
single most important things that you can do to save energy, and thus be very
“green”, is to have your heating system maintained regularly so
that it operates efficiently – that won’t earn you any “green”
brownie points under any green building guidelines that I have reviewed thus
far, it’s not sexy, but it is important and environmentally sound.
But
be warned – there will be trade-offs. You want to get as much “green
bang for your buck” as possible and you will find yourself in a constant
weighting game, for example comparing the waste factor of throwing away a working
appliance against the energy and/or water savings from installing a new one,
or the potential heat loss from a ventilation system versus the improvement
it will render in indoor air quality, or whether to allocate finite renovation
dollars to a solar hot water system or rain-water harvesting. Green building
is not dogma, it is a philosophy, ever pliable based on your own set of values.
Your personal priorities, and perhaps the particular micro-environmental issues
at your property location, will guide your choices among varying, and sometimes
competing, green options.
Being “green” is not checking
off the boxes on a predetermined checklist. “Greening” ought to
simply mean making the right combination of choices, in line with personal priorities
and budget, that maximizes energy efficiency, saves water, improves indoor air
quality and otherwise has a low or no impact on the environment. It’s
an attitude and a consciousness, and with the application of a little common
sense it’s easy, not expensive, and a way of life, like reading labels
in the grocery store. If every consumer asks “does that carpeting contain
formaldehyde” the same way we ask “does that snack contain trans
fats,” we will eventually change the world.
