Welcome to the Hourly Analysis Program
Welcome to HAP. Welcome to Carrier’s Hourly Analysis Program (HAP). HAP is a computer tool which assists engineers in designing HVAC systems for commercial buildings. HAP is two tools in one. First it is a tool for estimating loads and designing systems. Second, it is a tool for simulating energy use and calculating energy costs. In this capacity it is useful for LEED®, schematic design and detailed design energy cost evaluations. HAP uses the ASHRAE-endorsed transfer function method for load calculations and detailed 8,760 hour-by-hour energy simulation techniques for the energy analysis.

This program is released as two similar, but separate products. The "HAP System Design Load" program provides the system design and load estimating features. The full "HAP" program provides the same system design capabilities plus energy analysis features. This Quick Reference Guide deals with both programs.

HAP System Design Features. HAP estimates design cooling and heating loads for commercial buildings in order to determine required sizes for HVAC system components. Ultimately, the program provides information needed for selecting and specifying equipment. Specifically, the program performs the following tasks:

Calculates design cooling and heating loads for spaces, zones, and coils in the HVAC system.

Determines required airflow rates for spaces, zones and the system.

Sizes cooling and heating coils.

Sizes air circulation fans.

Sizes chillers and boilers.

HAP Energy Analysis Features. HAP estimates annual energy use and energy costs for HVAC and non-HVAC energy consuming systems in a building by simulating building operation for each of the 8,760 hours in a year. Results of the energy analysis are used to compare the energy use and energy costs of alternate HVAC system designs so the best design can be chosen. Specifically, HAP performs the following tasks during an energy analysis:

Simulates hour-by-hour operation of all heating and air conditioning systems in the building.

Simulates hour-by-hour operation of all plant equipment in the building.

Simulates hour-by-hour operation of non-HVAC systems including lighting and appliances.

Uses results of the hour-by-hour simulations to calculate total annual energy use and energy costs. Costs are calculated using actual utility rate features such as stepped, time-of-day and demand charges, if specified.

Generates tabular and graphical reports of hourly, daily, monthly and annual data
