Buildings & Energy Use
Buildings use energy … a lot of energy
38%
51%
62% 65%
70% 74% 75% 75%
Percent of carbon emissions from building sector
How do they use energy?
• Lighting
• Heating
• Cooling
• Ventilation
• Cooking
• Appliances
• Electronics
• Data Centers
• Elevators & Escalators
You know if your car or your refrigerator is efficient
Why not your building?
What if this were viewed as something consumers have a right to know?
The New York Story
New York City’s existing buildings are key to achieving its goal of 30%
CO2 reduction by 2030.
75% of NYC’s carbon
emissions come
from energy used in
buildings
And by 2035, 85% of
its buildings will be
buildings that
already exist today.
NYC’s core policies concentrate on its largest buildings.
2% of NYC’s one
million buildings account for
45% of all NYC
energy use
But three of the six requirements are about information…
• Energy Efficiency makes sense, but
it’s not happening to scale
• Providing information is the first step
because you can’t manage what you
don’t measure.
The cornerstone of the policies is benchmarking and disclosure.
• Every year every large building has to
measure its energy efficiency, with the
results being made public
• EPA’s Portfolio Manager – an online
tool Information gap on building
energy performance
• Solves the INFORMATION GAP
• The market needs to value energy
efficiency
• “Right to Know” for tenants,
prospective purchasers, etc
What the Data is
Showing
For the last three years, building energy use has been measured, and
you can go on line and look it up..
The very wide range of energy use indicates that significant citywide
savings will be very cost effective.
We can target the worst performing neighborhoods, which use more
than twice the energy per square foot as the best.
.
New York City’s buildings out-perform the national average, but are
in line with the Northeast.
Older commercial buildings seem to be more efficient than newer
buildings.
New York’s
comparatively older
building stock may
explain its relatively high
average scores
Neighborhood benchmarking scores seem to correlate with public health
issues.
This has spawned a data revolution in how buildings use energy
• We began with data about 54 buildings… now we have
information on over 10,000 large buildings annually in NYC
• There is starting to be data from other cities and portfolios
• Benchmarking data is being joined by audit and retro-
commissioning data
Snapshot of
Energy Efficiency Policies
in US Cities
Many cities have already adopted benchmarking, disclosure, and
audit and/ or retro-commissioning policies
9 cities require benchmarking of private sector buildings
7 cites also require public disclosure of the benchmarking scores
3 cities also require energy audits and/or retro-commissioning
Boston
New York
Washington DC
Seattle
San
Francisco
Minneapolis
Austin
Philadelphia Chicago
This amounts to a large area that is now required to annually
benchmark.
5.4 Billion sf
But we
need
to do
more.
