Hourly Analysis Program

HAP is a dual function program - full-featured load calculation and system sizing for commercial buildings plus versatile hour-by-hour energy modeling. It offers graphical input features for rapidly assembling a 3D building model. Thermal loads are calculated using the ASHRAE® Heat Balance load method. System components are sized using System-Based Design, which tailors sizing procedures to the specific system type. Energy modeling uses full 8760 hours-per-year analysis to evaluate the operation of a wide variety of HVAC system types. Energy costs are computed based on energy use, demand profiles and utility rate structures. A wide range of tabular and graphical outputs is available.

Block Load

Combines a full-featured design load calculation program with a simplified user interface. Perfect for engineers and contractors who need to generate loads quickly. Provides all of the sizing and load information needed to design HVAC systems and select air conditioning equipment. Offers a choice of calculation loads via the ASHRAE® Radiant Time Series or ASHRAE® Transfer Function Methods Suitable for both single and multiple-zone projects.

Building System Optimizer

Rapidly compares energy cost performance of HVAC system and equipment designs in commercial buildings. Supports applications in the schematic design phase of projects where multiple designs are being evaluated to identify one or a small group of alternatives with the most promising energy performance. A streamlined user interface allows analyses to be configured in minutes. Building System Optimizer is "powered by HAP" - calculations utilize HAP simulation engines to perform detailed hour-by-hour energy analysis for accuracy and credibility.

Engineering Economic Analysis

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.

Refrigerant Piping Design

Sizes suction, discharge and liquid refrigerant lines. Performs calculations for refrigerants R-134a, R-22 and R-717. Sizes horizontal lines and single and double suction risers per the ASHRAE Refrigeration Handbook.

System Design Load

Peak load calculation and system sizing for commercial buildings. Load calculations use ASHRAE® Transfer Function Method. System components are sized using System-Based Design, which tailors sizing procedures to the specific system type. Specific system and component sizing for a wide variety of airside system types. Includes a wide variety of graphical and tabular outputs.

PLV Pro

Rapidly calculates custom part load value (PLV) factors that can be incorporated into equipment specifications and can also be used to calculate a custom part load value (CPLV) for water-cooled chillers in a plant. The tool is easy to learn and fast to use, but at the same time performs detailed chiller plant analysis to derive the custom PLV factors.
