Cooling and Heating Requirements

Information about the cooling load, heating load, or both typically is crucial to identifying appropriate alternative energy efficiency measures and estimating potential energy cost savings. ASW's software library includes five different programs to calculate cooling and heating requirements.

• The Building Cooling Load program calculates a building's monthly peak and ongoing cooling-load profiles (a series of 24-hour profiles). It uses local weather data to establish the daily cooling-load profiles for a specific building application. A detailed building audit is needed to gather the data (e.g., wall, glass and roof area, number of people, etc.) to run the program.

  This program also concurrently identifies the ongoing circulating-air (cfm) requirement through the cooling-coils of a given air system to meet the sensible cooling-load requirements of the building.

  Once the base building model is established, any given variable (e.g., solar-factor of glass, percentage outside-air intake, lighting watts/sq. ft., etc.) can easily be re-evaluated to quantify its impact on the building's peak and ongoing cooling-load requirements.

• The Building Heating Load program calculates a building's monthly peak and ongoing heating load requirements (a series of 24-hour AC-profiles). It uses local weather data to establish the daily heating-load profiles for a specific application. A detailed building audit is needed to gather the data (e.g., wall, glass and roof area, number of people, etc.) to run the program.

• The Annual Heating Requirements program identifies a building's monthly heating requirements based on the building's square footage, the region where it is located, and the type of facility.

• The Annual Cooling Requirements program identifies a building's monthly cooling requirements based on the building's square footage, the region where it is located, and the type of facility.

• The Domestic Hot Water Requirements program identifies domestic hot water requirements and associated natural gas or electric consumption for a given installation. This program has built in basic hot-water requirements for different types of facilities.
