Did you know that more than 85% of multi-family buildings have inefficient heating systems?

Major complaints beside very little heat in a city apartment, is an overheated apartment. New Yorkers’ solution to overheated apartments for years has been to open up their windows, to release some of the heat trapped in their apartments. Many of these buildings are overheated simply because they have a hard time ensuring that every apartment is heated. So some apartments in the same building might be overheating while other apartments might just have enough heat to comply with local codes and laws.

There are solutions for these old apartment buildings that have problems with overheating by their water or steam radiators. The EPA, EEFA, and other environmental agencies recommend installation of thermostatic radiator valves or TRVs on every radiator in the building. Most TRVs do not require electricity, are easy to install by almost any handy person, and are very economical. TRVs have a built-in sensor that opens and closes the radiator according to the temperature in the room, providing an individualized comfort control to any room.

Case studies

  • Engineering Tomorrow lowers apartments’ heating cost to less than $50 annually

    In recent years, average rent for a one-bedroom apartment in Brooklyn’s Bushwick neighborhood has skyrocketed to more than $3,000 a month, excluding utilities. That’s why New York City’s Department of Housing Preservation and Development (HPD) and Ridgewood Bushwick Senior Citizens Council (RBSCC) came together to develop Knickerbocker Commons.

    Engineering Tomorrow makes winter safer for city of Buffalo

    According to the National Weather Service, a series of lake effect events and clipper-type systems dumped 112 inches of snow on Buffalo, New York, in the winter of 2014-15. In an area accustomed to harsh winters, this was still unusual—about 18 inches above normal. But even this impressive amount of snow was no match for the Danfoss snow melt system installed at Canalside, the heart of Buffalo’s waterfront revitalization.
