As the original technical software partner of ACCA, [3] Wrightsoft Corp became the first HVAC software company to create a computerized version of their Manual J, Manual D, and Manual N calculation methods. The Air Conditioning Contractors of America and Wrightsoft released the very first Manual J Load calculation software (Right-J) in February ...
Construction cost estimating software is computer software designed for contractors to estimate construction costs for a specific project. A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract. Some architects, engineers ...
The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
The benefit of software-enabled collaboration is the ability to identify the full range of energy efficiency options that may be applicable to the specific building under study with "live time" cost and benefit estimates supplied by local contractors.
The cooling load [3] is calculated to select HVAC equipment that has the appropriate cooling capacity to remove heat from the zone. A zone is typically defined as an area with similar heat gains, similar temperature and humidity control requirements, or an enclosed space within a building with the purpose to monitor and control the zone's temperature and humidity with a single sensor e.g ...
The Home Energy Saver is built on DOE-2, a computer program for building heating and cooling energy analysis and design. [3] DOE-2 performs a thermal load simulation that accounts for heating and cooling equipment and thermal distribution efficiencies, infiltration, and thermostat management. [4]

In the performance approach, a baseline energy cost budget (ECB) is established, based on the building size and program. This baseline ECB is established using building performance simulation to model a building with the same size and program as the project building, built according to the prescriptive requirements of ASHRAE 90.1 (sections 5-10).
