Good
for the Environment -- Good for the Economy!
Our buildings use too much energy today!
Providing energy services to residential
buildings uses about 15.4 Quadrillion Btu (15.415 Btu) of primary
energy per year, and despite progress towards better efficiency over the last
30 years, these structures still use about 60 percent more energy than
necessary according to analysis by independent groups like Rocky Mountain
Institute (RMI) and the Alliance to Save Energy (ASE).
Consumers pay over $175 billion per year for
utility and fuel bills, but the "price" for their energy consumption never
fully recognizes the external societal costs -- externalities -- resulting from
excessive energy consumption, and the large degree of hidden subsidies
underlying conventional energy resources use by the economy. Externalities
impact the common areas of the environment -- the atmosphere, rivers, public
forests, lakes, and oceans -- because economics has not yet some to grips with
internalizing these costs and impacts over the life of an action or investment.
Indirectly, consumer health problems and lost productivity are the net results
of a marketplace in which environmental costs of inefficient energy use are
borne by society, because they are not accurately reflected in the price of
energy paid by consumers, industry, and the economy. The same forces
are at work in the allocation of other resources to building construction and
renovation, development of land, emplacement of added infrastructure to support
the development, and in the provision over lengthy life-cycles of utilities and
services to such developments on the community and regional scale.
Important Issues:
There are numerous important issues facing
society when it comes to energy efficiency:
Energy Use and the Ambient Environment -- How does
resource efficiency help? What measures quantify value? Energy production and
use is a big factor in environmental pollution. How can what is know about
energy efficiency in residential buildings be used to reduce pollution from
energy waste. Indoor Environment
-- Better indoor environmental conditions means and improved quality of life.
Understanding the interactions of indoor environmental parameters within, and
as a result of, the design and refurbishment of buildings and their land use is
vital for improving how the built environment performs and reducing its impact
on the global environment. Indoor air pollutants and other processes that
impinge on human health and influence productivity can be effectively managed
both in new construction and in rehabilitation of existing structures.
Air
Pollution -- Excessive energy utilization in the operation of
buildings, combines with other building-related energy use in production of
building materials, transportation of such materials to distribution centers
and job-sites, re-working of materials on site (power tool energy usage),
compensation for errors (tear-out & re-do) through insufficient planning or
training of trades/labor, and removal of damaged or destroyed materials to
land-fills, work together to elevate building related air pollution.
Considerations of the full life-cycle energy use in building is
needed.
Water
Pollution -- Employing strategies to boost energy and resource
efficiency in development means big gains in reducing water pollution. There
are numerous opportunities for reduction in water pollution, and in the volume
of water use associated with residential development and occupancy.
Land
pollution-- More efficient energy use throughout the development,
operation, and demise of residential structures will strongly influence local
and regional land pollution impacts. Resource efficiency, including reductions,
reuse, and recycling of natural non-renewable resources (steel. minerals,
petrochemicals, etc.) means less pollution of land, tailings, and landfills.
Optimization of the use of renewable and non-renewable resources in light of
durability, recycling, reuse, structural, aesthetic, and economic concerns
should be explored. Considerable research is underway in the area of material
selection and design to lessen construction and demolition wastes.
Recognizing
Externalities -- The societal value of avoided pollution is
contained in reducing the "externality cost." An externality is any cost the
consideration of which is specifically or inadvertently not included in the
price charged when using a technical process or application that generates a
product or good, using energy or other resources.
The societal value of avoiding externalities (estimates) just in
terms of Air-pollution emissions related avoidance includes:
International Energy Conservation Code
-- full implementation could save about 750,000 Tons/yr, worth
nearly $ 58 million to society (new homes) More Energy Efficient
Windows (Low-E high performance glazing) -- 17.5 million Tons/yr,
worth about $ 1.1 Billion to society Enhanced Low-income
Weatherization -- 28 million Tons/yr, worth $1.9 billion to society
Foundation Thermal Insulation -- 30 million Tons/yr, worth $ 2.1
billion to society
First Cost versus Long-term
Value
The market place creates tension between
consumer demand for products and services that provide rapid payback, versus a
life-cycle analysis approach which allow consideration of wider variables
affecting the building's environmental performance. The trade-offs between
environmental performance and economic performance are not necessarily negative
and the relationships need to be explored and recommendations based on sound
analysis. The long term economic value of a building with higher
overall environmental performance may be higher than a conventional building of
similar design. Listed below are just a few areas where such trade-offs should
be investigated: * A better thermal envelope reduces (or eliminates)
need for conventional H/AC equipment resulting in net cost savings and very
much lower pollution emissions; * Improved indoor air quality lessens
"sick-time" and boosts productivity netting $100 or more per square foot from
the investment; or * Use of locally produced or manufactured building
materials improves local economic conditions (creates jobs), lowers
transportation related air-pollution (not importing saw-timber from outside the
area), improves building performance (designs and products tailored to local
climate).
Opportunity Cost to
Society of Environmentally Inefficient
Buildings
The costs to society of inefficient energy
use represents a perverse incentive to polluters, and helps reduce migration up
the social ladder to home ownership due to cash flow from lower income persons
being misdirected to excessive energy payments. Where possible, the social
equity issues of environmentally insensitive residential development should be
addressed. Industry
Benefits
Green building (energy and resource efficiency)
should recognize to the extent possible the benefits that could accrue to the
building industry from voluntary adoption by builders, developers, utilities,
communities, and other entities. * Consumer "green" recognition is
becoming mainstream (2006). * Potentially huge markets; within U. S.
and Exports * Generating added demand for lower impact products and
services * Creating new well paying "enviro-jobs" assisting with
conversion from Military/Industrial to Eco/Industrial Complex
