|
E20-II is a collection of software programs created specifically for the HVAC system designer. These programs are tailored to increase productivity and accuracy, improve analysis capabilities and job documentation, and add a level of "marketability" to a designer's estimates. Individual programs are available to assist in heating & cooling load estimating, annual building operating cost estimating, refrigerant piping system design, and economic life cycle analysis. These programs are written by HVAC systems engineers for HVAC systems engineers, and are supported by more HVAC system engineers with years of field application experience.

NEW: Use HAP to obtain EPACT building tax deductions.
HAP is a dual function program - full-featured load estimating and system sizing for commercial buildings plus versatile hour-by-hour energy and operating cost analysis. Thermal loads are calculated using the ASHRAE-endorsed Transfer Function load method. System components are sized using the System-Based Design concept, which applies the ASHRAE-endorsed Heat Extraction Methodology to link system performance to building thermal loads. Energy analysis uses full 8760 hours-per-year analysis to evaluate the operation of a wide variety of air handling and plant equipment. Operating costs are computed based on energy use and demand charges. A wide range of tabular and graphical outputs is available.

Tool used to compare the lifecycle economics of alternative designs for HVAC systems and buildings. The program permits four types of economic analysis studies to be performed ¿(1) simple payback analysis, (2) simple cash flow analysis, (3) private sector lifecycle analysis, (4) public sector lifecycle analysis. All four are bundled in one seamlessly integrated package.
