Retrofitting apartment buildings for fuel savings - Inside Construction

As rising fuel prices increase the operating costs of multifamily dwellings, owners and managers are retrofitting their properties with technologies that improve energy efficiency.

Their approach has broadened to include 1) the elimination of fuel and water waste, 2) lowering the cost of maintaining heating and domestic hot water systems, and 3) reducing the amount of management time needed to achieve these goals. In addition, the technology chosen should be economical and easy to install.

Fuel Savings

There have been many buildings--notably low-income 401 properties--where excessive heating costs are due to antiquated monitoring and control of boiler cycling and domestic hot water systems. However, owners and managers of these and other properties, including middle-and upper-income rental buildings, condos, and coops, are turning to low-cost computer technology to reduce their fuel bills by as much as 40 percent or more.

They have installed Fuel Computers supplied by U.S. Energy Controls, which, by means of outdoor and indoor temperature sensors and electric and electromechanical controls, permit boilers to cycle only when building interiors actually need heat
