HVAC Solutions to Increase Energy Efficiency

A George Washington University alumnus, Avi Polischuk owns and operates R&S United Services, based in Amityville, New York. Under the leadership of Avi Polischuk, the company focuses on bringing the highest level of energy efficiency to high-rise construction projects; in particular, through the use of sophisticated heating, ventilating, and air conditioning (HVAC) systems.

In 2013, residential and commercial buildings were responsible for 40 percent of the United States’ total energy consumption. On average, 21 percent of such energy use is strictly for cooling and heating residential buildings, such as condominiums. A building owner, depending on preference, has several HVAC options for reducing energy expenses, including the following:

1. Water-cooled VRV, also known as VRV-WIII, utilizes minimal energy to control different zones within an infrastructure and accommodates both open floor plans and cellular applications. Composed of unified condensing units, the VRV-WIII system has the ability to recover energy through a water-loop application. It is an energy-efficient alternative to traditional water-source heat pumps or infrastructures requiring a water-cooled chiller.

2. An evaporative pre-cooling system leverages adiabatic cooling to lower temperatures by as much as 30 percent. Working in conjunction with air-cooled chillers, the system decreases electricity use by reducing the temperature of the air surrounding the unit. As a result, the refrigerant cycle works more effectively and more heat can be released.

3. A variety of geothermal heat pumps are rated by Energy Star as the most efficient pumps in the market. Among the energy-efficient models are the American Standard A1GX Series with Premier Control, the ClimateMaster Tranquility 30 (TE) Series with iGate Controls, and the GeoStar Sycamore Series with Aurora Control, all of which offer variable-speed options that improve indoor comfort and save on electrical expenses.
