Welcome to the home page of ASHRAE Technical Committee 4.7. This technical committee is concerned with identifying, evaluating, developing, and recommending procedures for calculating energy performance of buildings. TC 4.7 is currently responsible for Chapter 31 'Energy Estimating and Modeling Methods' of the ASHRAE Fundamentals Handbook.

Sub-Committees

TC 4.7 has a number of sub-committees. These are:

• Handbook
• Applications
• Inverse Methods
• Simulation and Component Models

Research and program items are normally dealt with by each of the sub-committees (except Handbook) and recommended to the main TC.

TC 4.7 Standards

This TC is responsible for the following standards:

• ANSI/ASHRAE Standard 140-2001: Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs.

This standard 'specifies test procedures for evaluating the technical capabilities and ranges of applicability of computer programs that calculate the thermal performance of buildings and their HVAC systems..

Other TCs

ASHRAEs technical committees are organized into sections. TC 4.7 is part of Section 4.0 Load Calculations and Energy Requirements. The TCs in Section 4.0 are:

• TC 4.1 Load Calculation Data and Procedures;
• TC 4.2 Weather Information;
• TC 4.4 Building Materials and Building Envelope Performance;
• TC 4.5 Fenestration;
• TC 4.7 Energy Calculations;
• TC 4.10 Indoor Environmental Modeling;
