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.
