E20-II HVAC System Design Software   What Is E20-II ? 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. E20-II Software Modules Load & Energy Analysis HAP (Hourly Analysis Program): Load Estimating & Energy Use Analysis System Design Loads: Cooling and Heating Load Estimating Block Load for Windows: Simpler (but still Accurate) Load Estimates Mechanical Design Refrigerant Piping Analysis: Sizing & pressure calculations Economics Engineering Economic Analysis: Lifecycle economics for HVAC systems
