e know U.S. buildings,
homes and appliances
have become more efficient. In fact, greenhouse gas emissions from commercial and residential
sectors have increased only 2% in the
last two decades. That doesn’t seem
too bad if our view is focused only on
what’s happening at the site.
Zooming out to see the whole
picture shows us what’s happening
off-site has more serious environmental impacts. Higher electricity
consumption in the commercial and
residential sectors has increased
indirect emissions by 42% since
1990. That’s off-site emissions
caused primarily by burning fossil
fuels at power plants.
So, can we say a building is high
performing without considering its
emissions? The editorial advisory
board of this magazine says no. In
future issues, annual CO2 emissions
will be added to the Energy at a
Glance sidebar included in every
HPB case study.
“WHERE’S THE Carbon Footprint?” by board members Lindsay
Audin and Adam W. Hinge, P.E.,
Member ASHRAE, explains how
on-site and off-site CO2 emissions
will be calculated using guidance
from the EPA and international
standards, and how CO2 emissions
impact building design.
“If we were charged for disposal
of CO2 emissions in the same ways
we incur maintenance and replacement costs (e.g., to properly dispose
of linear fluorescent lamps), that cost
would be factored into a design’s
economics, possibly altering one’s
equipment choices,” say the authors.
The authors also explore the
complexities of renewable energy
certificates (RECs), which represent the environmental attributes
of one MWh of electricity produced
through renewable energy generation. A benefit is that RECs are not
location specific. However, are they
equivalent to on-site renewables?
The authors tackle these issues
starting on Page 50.
CONNECTIONS are a theme in this
• Twelve | West in Portland,
Ore., is built on the former site of a
derelict building and provides connection between the city’s emerging West End neighborhood and
the surrounding thriving neighborhoods.
• McCormick’s distribution center
joined customer demand with cost
efficiency to reduce its environmental impact with a new solar array
and energy efficiency measures.
• Earth Rangers Centre near
Toronto uses Animal Ambassadors
at its headquarters to link children
• Chandler, Ariz., sought to reconnect to its community by building the new City Hall in the heart of
its run-down city center.
WE HOPE you enjoy this edition.
Stay tuned for our new monthly
enewsletter coming this spring.
