The Mile-High City has joined the ranks of 20 other cities requiring large commercial buildings to report energy consumption data. The energy transparency initiative is
aimed at reducing the city’s greenhouse gas emissions below 1990 levels by 2020. Building energy use
is responsible for about 57% of Denver’s carbon emissions, so city officials believe the new benchmarking
ordinance is poised to make an impact.
Starting in June 2017, commercial and multifamily buildings over 50,000 square feet will be required
to report their ENERGY STAR score as determined by
Portfolio Manager. Buildings over 25,000 square foot
will have to report starting in June 2018. The city will
make all of the scores available to the public each year.
The ordinance is based on the recommendations of
the Energize Denver Task Force, a group comprised
of property managers, building owners, investors, utility representatives, energy efficiency contractors and
other stakeholders. The task force also recommended
periodic cost-effective, quick-payback improvements
for buildings that don’t place in the top quartile of
performance; this proposal has not been presented to
the city council but was vetted for further action in the
future if needed.

INCREASES IN SOLAR, WIND AND OTHER
CLEAN ENERGY GENERATION AND
Renewable electricity generation grew to 16.7% of total installed capacity and 13.8% of total electricity generation during 2015, according to the Renewable Energy Data Book.
Published annually by the National Renewable
Energy Laboratory (NREL) on behalf of the
Department of Energy’s Office of Energy Efficiency
and Renewable Energy (EERE), the data book includes
national and international energy statistics such as
renewable electricity generation, renewable energy
development, clean energy investments and technology-specific data and trends.
“Since it was first released in 2009, the Renewable
Energy Data Book has provided useful insights for poli-
cymakers, analysts and investors,” says Philipp Beiter,
Energy Analyst at NREL. “The 2015 version of the data
book highlights the ongoing trend of growing renew-
able energy capacity and generation in the U.S. and
Insights in the data book include:
■ Renewable electricity accounted for 64% of U.S
electricity capacity additions in 2015, compared
to 52% in 2014.
■ Renewable electricity generation increased 2.4%.
Solar increased by 35.8% (to 11. 7 terawatt-hours),
and wind electricity generation increased by 5.1%
( 9. 3 terawatt-hours).
■ Wind electricity installed capacity improved by
more than 12% ( 8.1 gigawatts), accounting for more
than 56% of U.S. renewable electricity capacity
installed in 2015.
■ Solar electricity installed capacity rose by 36%
( 5. 6 gigawatts), accounting for nearly 40% of newly
installed U.S. renewable electricity capacity in 2015.
■ California, Washington and Texas led the U.S. in
installed renewable electricity capacity.
■ Oklahoma, North Carolina, Utah and Kansas had the
highest growth rates in installed renewable electricity
■ Installed renewable electricity capacity climbed to
more than 29% of total electricity capacity worldwide in 2015.
