conditioners will more than triple by
2050, equal to China's electricity
demand today " and the " answer lies
first and foremost in improving the
efficiency of air conditioners, which
can quickly slow down the growth in
cooling-related electricity demand. "
There are multiple project feasibilities
underway across the state of
New York, funded by the New York State
Energy Research and Development
Agency (NYSERDA) as part of the state's
initiative for achieving its carbon
reduction goals, specifically the use of
district energy solutions for heating and
cooling (PON4614). The developer's
primary focus is to deliver minimum
code compliant buildings at the lowest
capital expenditure cost, rather than
longer term operating expense costs
when considering heating and cooling
options. While ticking the electrification
box, opting for the cheapest solution
does not provide the most energy
efficient option, especially during the
coldest and hottest times of the year
(peak periods). The go-to solution for
heating and cooling multifamily
housing is seen as variable refrigerant
flow system/package terminal heat
pumps with electric boilers for providing
domestic hot water. Several large-scale
feasibility studies done by Endurant
have shown that electrical usage drops
between 44-50% when using a hybrid
ground sourced heat pump solution
compared to these current solutions.
The growing worldwide movement
towards electrification is an essential
piece of the strategy to meet global
carbon reduction goals; however, that
transition itself creates its own
complications (as seen in the recent
example of California). The Urban Green
Council, a New York-based nonprofit,
has a grid mapping tool that highlights
these wider issues. This is clearly
demonstrated in New York City, for
example, where the growing concern is
that as more buildings become electrified,
connectivity during peak periods
will increasingly lead to blackouts.

Foundation contractors can help
aid electrification as well as
address peak connectivity issues.
By utilizing geothermal loops
installed within building foundations,
connected to a ground
sourced heat pump to deliver a heating
and cooling solution to the very
building they support, these systems
can play an essential part in mitigating
electrical demand while delivering a
low carbon solution.
