F

or decades, local energy codes have defined
the least efficient structure that could be
legally built. Although codes have become
stricter, they still fall short of industry
experts' recommendations towards zeronet energy. For projects that cannot offset energy
use on site, the goal should be creating standards for
ultra-low energy homes and commercial spaces on
par with ZNE.
Intensifying pressure to meet energy reduction
and climate action goals has some policymakers
rethinking the role of energy codes and their potential
to dramatically reshape the efficiency outcomes for
local building stock. As a result, broader application of
"stretch codes" has emerged as a promising solution
that jurisdictions can use to set a long-term vision for
efficiency stringency far into the future.
Stretch codes represent a wholesale disruption of
the current paradigm for energy code development.
Incremental improvements to the current version
of the two national model energy codes - ASHRAE
90.1 and the International Energy Conservation
Code (IECC) - happen every three years and
traditionally address provisions such as increasing
insulation values or equipment standards. But these

prescriptive standards can only go so far towards
achieving higher levels of efficiency in building
design and construction.
Alternatively, stretch codes require jurisdictions
to set goals for achieving zero or ultra-low energy
use in new construction by an end date - 2030 is a
common target - and to provide a plan to increase
requirements incrementally until the goals are
met. The Northeast currently leads the country in
energy stringency in codes and a new study by the
Northeast Energy Efficiency Partnerships (NEEP)
finds that the majority of states in the region could
achieve ZNE requirements by 2040.
Stretch codes (sometimes referred to as 'step' or
'reach' codes) are proving to be a critical policy lever
for local governments that understand they must
accelerate the pace of progress in order to mitigate
the effects of climate change. U.S. commercial
buildings and residential households consume
over 40% of the nation's total primary energy and
contribute roughly 40% of the carbon emissions. To
date, hundreds of entities across the country have
adopted goals to reduce these carbon emissions and
meet the 2030 Challenge, which aims to make all
new buildings and major renovations carbon-neutral
