The green roof isn’t the only thing that makes our subject building unique

Its recently completed a major transformation, taking it’s inefficient heating system that hasn’t changed much over the past century and fully updating it with the most cutting edge and innovative equipment available. The installation of the Daikin AURORA inverter heat pumps throughout the building, provide the residents with increased comfort and control while reducing the cost to heat the building and reducing the buildings environmental impact.

Buildings are a main contributor of greenhouse gas emissions. Nationwide across the U.S., buildings are responsible for approximately 40% of greenhouse gas emissions. While in dense urban areas like New York City, they can be responsible for more than 70% of greenhouse gas emissions. Decarbonizing a building’s space heating system is a key strategy to significantly reducing a buildings emission while providing many other benefits.

The Daikin AURORA ductless heat pumps were the ideal solution to provide year-round comfort for the cold-climate experienced in New York City, as they provide up to 100% heating capacity at 5F and operate efficiently as low as -13°F ambient temperature.

Renovation Ready

Daikin Multi-zone ductless heat pumps were easily insalled into each unit in this 10-unit multifamily building. Ten systems were installed in total: one for each residece. Each system is comprised of an outdoor unit that is then connected to three or four ductless indoor units by small refrigerant piping. If you look closely at the floor, you can see there used to be an old cast-iron radiator in the location where a new ductless inddor unit for the heat pump is located.

Daikin ductless technology is the perfect solution for a building like this, as:

• It provides great installation flexibility and a wide choice of styles.
• It provides independent temperatre control for each residence and zone within each residence.
• It offers a wide range of systems, which up to 8 indoor units can be connected.
• The discrete, robust outdoor units can easily be mounted onto a roof, terrace, or nearly any exterior wall of the building.

Daikin Ductless: The Possibilities are Endless

There are tens of thousands of buildings similar to this one throughout dense urban cities in the Northeast United States. Being built eighty or more years ago, means these buildings may only have hydronic heating from a bolier - which can be inefficient and uncomfortable while also unable to provide cooling during the warm summer months.

According to Urban Green Council, "the best heat pump conversion targets are owner-occupied buildings with one-pipe steam heat systems that use expensive fuels."* When these buildings use fuel oil for their boiler or electric resistance heating, there is often a significant cost savings by switching to efficient inverter-driven air source heat pumps.

In addition to the energy cost savings, oftern an even more valuable component to the residents can be the comfort benefits. Ductless heat pumps allow residents to customize their comfort and enable multiple thermal zones per residence. For example, the building in New York City had one boiler which treated the entire building as one thermal zone. With the installation of ten air-source heat pump system, the building now has over 30 zones for both heating and cooling.

Why Daikin?

As the World's No.1 indoor comfort solutions company, we know that the air we share is the only air we have. That's why we're on a mission to change the way people think about making the air in their homes more comfortable. We create next-generation heat pump HVAC and air quality systems with technology that helps reduce our carbon footprint and the world's reliance on fossil fuels.

Inverter Air source Heat Pumps Decarbonize Buildings

Many states and cities have created greenhouse gas emissions reduction commitments. The current strategy being pursued to achieve these targets is to convert end-uses from fossil fuels to electricity and then reduce the emissions of our electiricty generation by incorporating more renewable energy.

The largest end-use in our buildings that use fossil fuels is space heating. Since air source heat pumps enable the efficient use of electricity for heating, they are being looked at as a key technology to achieve long term climate goals.

Even with emissions associated with today's electricity generation, air source heat pumps reduce the greenhouse gas emissions associated with spaced heating when compared to the most prevalent heating system types in the US, including fuel oil, natural gas, propane, and electric resistance.
