Let's talk about buildings.

Buildings in New York

Buildings in New York State are older than the national average, which means there are many opportunities to improve efficiency.

Weather, geography, and building sizes vary across the State, so efficient, cost-effective solutions must respond to these variations.

Due to the cost of fuel and existing inefficiencies in homes, people may spend a significant portion of their income on energy bills. In New York State, nearly half (48%) of the households are low-to-moderate income. For New Yorkers, energy affordability is important.

Buildings that are well-insulated and sealed are more efficient. High-efficiency appliances and clean technology upgrades like solar panels or heat pumps increase efficiency even more, and reduce emissions.

New York State's residential and commercial building sectors encompass:

New York has more than 6 million residential and commercial buildings, 7.4 million households, and 5 billion square feet of commercial and institutional space.

Direct emissions from buildings account for roughly 30% of greenhouse gas emissions in New York State, driven mainly by fossil fuel-based space and hot water heating. When adding the emissions from generating the electricity used in buildings, that figure rises to over 40%.

Building Solutions

Different Types of Buildings Require Different Solutions


Houses

Heat pumps were once considered to work well only in moderate climates. However, as technology has evolved, heat pumps can now keep homes comfortable year-round, even in colder climates. This technology can be up to four times more efficient than traditional heating systems.

A ground source heat pump has an underground heat exchanger. An air source heat pump is aboveground.

How does a heat pump work? A heat pump pulls heat from the air (air source heat pump) or from underground (ground source heat pump) and uses it to heat your home in the colder months. In the summer, the process works in reverse. It moves the heat from within the building to the outside air or to underground. A refrigerant is used to move the heat from one location to another.

While manufacturers' capabilities vary, in the coldest regions of Upstate New York — where below-zero days can be expected — cold-climate air source heat pumps are an efficient, convenient solution for combined heating and cooling.

Hear Seth’s story, a Coxsackie, NY homeowner who installed heat pumps in 2017. Seth has reduced his family’s reliance on fuel oil (a fossil fuel) and saved money on his energy costs. He describes the heat pump installation process and what life has been like since his installation.

Apartments

Air source heat pumps can be installed in spaces with or without ductwork making them a great solution for many residences.

Gradient's highly efficient cold-climate heat pump for heating/cooling compact spaces received support from the 2022 Clean Heat for All Challenge. The initiative, spearheaded by multiple New York State agencies, supports the development of new electrification products that can better serve the heating and cooling needs of existing multifamily buildings and hasten the transition to fossil-free heating sources.

A new window unit style of heat pump is being developed to serve apartment buildings.

By leveraging New York City Housing Authority's portfolio, which includes more than 2,000 residential dwelling buildings, the Clean Heat for All Challenge is designed to spur innovation and growth of heat pump technology.

This video features heat pump technology being developed for public housing.

Community Networks

Also known as clean district energy or a thermal network, community heat pumps leverage different heat sources, including the heat beneath the Earth's surface, and move it through an underground distribution network to groups of buildings.

A large geothermal residential development in New York will serve 5 interconnected buildings, including a 37-story and a 20-story tower, with a vertical closed-loop geo-exchange system. Watch this video to learn more:

New York supports the detailed design and engineering of innovative thermal energy projects through a new  Large-scale Thermal Program .

Competitively selected sites will develop designs that will accommodate their heating, cooling, and hot water needs by utilizing thermal sources such as ground heat, wastewater, waste heat recovery from industrial processes, and thermal energy storage. 

Commercial Buildings

Energy efficiency and electrification will play a dominant role in putting New York State buildings on a course to decarbonization while creating better working spaces for New Yorkers. Decarbonization will also drive economic opportunity by growing clean energy jobs and businesses.

Investing in building energy efficiency and designing for flexible building energy loads can also reduce the amount of electric grid investments needed for a reliable and resilient grid.
