According to a study by McGraw-Hill Cos.,
green—or environmentally friendly—buildings
constitute less than 5 percent of total construction today;
however, that figure is projected to double by 2010. Consciousness-building
media and events are occurring around the world to alert
us to the fact that the ecological health of our planet
is faltering. Recently the movie, “An Inconvenient
Truth” made us highly aware of the issues at hand.
The Live Earth concerts on 7/7/07 were simultaneous concerts
on all seven continents to raise awareness. The good news
that was conveyed is that if we act now to change our behaviors,
we can alter our ecological path.

From a vertical building perspective,
it is beginning to happen in Las Vegas with new developments
such as MGM Mirage’s City Center and Sullivan Square
reaching for LEED status. LEED is an acronym for Leadership
in Energy and Environmental Design, a status bestowed by
the U.S. Green Building Council to those who meet the stringent
criteria. Other countries have similar organizations: The
UK has BREEM, Australia has Green Star, Singapore has BCA
Green Mark, etc. So, how does a developer obtain LEED status?
The developer—through the architect who is fluent
in such criteria—designs the building to emit less
carbon and to offset remaining carbon emissions. The goal
is to become “carbon neutral” or close to it.
According to the dictionary, “carbon neutrality”
has two principal meanings. It can refer to the practice
of balancing carbon dioxide released into the atmosphere
from burning fossil fuels by utilizing renewable energy
that creates a similar amount of useful energy, so that
the net carbon emissions are zero; or alternatively using
only renewable energy.”
The
criteria associated with LEED may include such things as
incorporating BIPVs (building-integrated photovoltaics,
or solar energy). This is certainly appropriate in Las Vegas’
desert climate, where there are more than 300 days of sunshine
a year. Use of wind turbines can be cleverly built into
the façade of a building. In a number of renderings
that I have seen, the turbines become an integral part of
the architectural design and actually add an intrigue of
moving art to the look of the building. Harvesting of rainwater
(in climates other than Las Vegas!) can be quite effective.
Attention to the exterior envelope of the building such
as use of double-paned low-e windows, incorporating use
of low-VOC (volatile organic compound) or no-VOC paints
and adhesives inside the building to improve air quality,
use of recycled content or materials, recycling of construction
waste and on and on! As architects and developers continue
to explore ways of being more ecologically responsible,
even more innovative ideas are springing forth on how to
improve our “carbon footprint” or even to become
“carbon neutral.”
Ideally, the site or the location of
the building itself, should be centrally located or close
to public transportation. Over the last several decades,
cities began to sprawl farther and farther away from the
hub. The concept was to live in the suburbs and commute
to work in the city’s core. In most cases, the city
did not have proper public transportation (light rail, commuter
trains, subways, etc.), therefore there was an increase
in automobile commutes, in most cases with only one person
per car. This of course increases traffic congestion and
subsequently carbon emissions. So, living in a vertical
property in the hub and/or close to public transportation
is a huge contribution to our “earth savings account.”
Of course, working at home or within the same building (live/work
buildings) is an enormous benefit. Mixed-use properties
are even better—living, working and recreating without
stepping on the gas!
The
profound architect, Norman Foster, once said, “I urge
you to think in verticality, for sustainability.”
In keeping with this goal, he designed the 46-story Hearst
Tower in New York City. This was the first building to break
ground after 9/11 and received the 2006 Emporis Skyscraper
Award. The first green building in New York City, it was
constructed of 80 percent recycled steel and is designed
to use 25 percent less energy than the minimum for the city.
The Tower received the gold designation from the LEED certification
program.
If you think about it, high-rises themselves
are assisting in the cause. Most of the buildings completed
in the last decade have double-paned, low-e windows. They
generally have an abundance of natural light. In my high-rise
unit where I live, I have no need to turn lights on during
the daylight hours.
A vertical neighborhood also has economies
of scale: one HVAC source (the cooling towers or the central
plant of a high-rise), one garbage truck can pick up an
entire neighborhood of garbage with one stop, one recycling
location for pick up, only one landscaped garden requiring
water, one swimming pool, and interior common hallways that
insulate the units so that every time you open your door,
you are not subject to the exterior temperatures. The advantages
of high-rises, as far as the environment is concerned, are
vast.
However, existing buildings can be run
even more efficiently. Some facilities managers are using
energy management software to track energy usage of their
large equipment such as cooling towers. They are analyzing
surges in energy usage on a daily, weekly, monthly and seasonal
basis. Questions are being asked, such as, Can this system
be optimized in some way? Can we incorporate renewable resources
into our energy needs?
The
consensus seems to be that even small changes that we make
in our everyday lives make huge differences. Even within
an individual unit there are things that owners can do to
become more energy efficient. If possible, convert to a
“tankless” water heater, which heats on the
spot versus an 80 gallon tank that has to continually keep
the large water tank hot; energy-saving light bulbs and
dimmer switches; turn lights off when leaving a room; install
programmable thermostats; change air filters regularly;
switch to new energy-efficient appliances (look for Energy
Star on the label); recycle; convert to low-flow showers
and toilets; and turn off or unplug electrical appliances
when you are not using them. What is your carbon footprint?

I leave you with the Property Council
of Australia’s definition of “sustainable”—“Development
that meets the needs of the present without compromising
the ability of future generations to meet their own needs.
It calls for a triple bottom line approach to business,
balancing environmental, social and economic accountability.”
It seems that all people and all countries on the planet
now have a cause that brings us closer than ever before,
united in a single common goal—a planet to call home!
Think “sustainably”!
Until next month, here’s
wishing you “elevated” sales!
