Solar and Other Renewable Energies
ASHRAE Technical Committee 6.7

Scope of TC 6.7

TC 6.7 is concerned with all equipment, processes and systems which collect, convert, store and utilize solar energy or other renewable energy sources. Overlap with other TCs is recognized where specific systems are included to utilize or distribute energy as heat or electricity.


The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years.

The Handbook can be purchased at the ASHRAE Bookstore by clicking on this link.

If you are a voting or corresponding member of TC6.7 you can provide inputs and edits to TC6.7 cognizant chapters in the ASHRAE Handbook Central.  The handbook central ( can be found under communities - standing committees on the front page.  Then scroll down to and click on Handbook Committee (under the heading "Committees that report to Publishing and Educational Council".  On the Handbook committee page, scroll down and click on Handbook central and then click on the Information and tools for ASHRAE TCs developing Handbook Content link.  Then click on Log in to the Authoring Portal (will only work with Internet Explorer).  Please use "track changes" so it is possible to see what edits/suggestions you make and who made them.  If you do not track your changes, it is unlikely that your changes and suggestions will be noticed and therefore included in the updated versions.

TC 6.7 is responsible for the following chapters in the ASHRAE Handbook:

HVAC Applications: Solar Energy Use

The sun radiates considerable energy onto the earth. Putting that relatively low-intensity (rarely over 300 Btu/h·ft2 [950 W/m2]) energy to work has lead to the creation of many types of devices to convert that energy into useful forms, mainly heat and electricity. How that energy is valued economically drives the ebb and flow of the global solar industry. This chapter discusses several different types of solar equipment and system designs for various HVAC applications, as well as methods to determine the solar resource.

 The ASHRAE HVAC APPLICATIONS HANDBOOK may be purchased from the on-line bookstore by clicking on the highlighted text.

HVAC Systems & Equipment: Solar Equipment

Solar energy use is becoming more economical as the cost of energy continues to climb, especially with increasing government and utility incentives as well as growing interest in green and/or sustainable construction. In addition, many countries consider solar and renewable energy as a security measure to ensure the availability of power under adverse conditions. While the United States continues to grow its solar industry, China, Europe, Asia, and the Mediterranean basin are leading development of advanced manufacturing techniques and applications. However, equipment and systems are still very similar in all markets; therefore, this chapter primarily discusses the basic equipment used, with particular attention to collectors. More detailed descriptions of systems and designs can be found in Chapter 35 of the 2011 ASHRAE Handbook—HVAC Applications.

Comment on the Handbook: ASHRAE welcomes your comments on the Handbook or a specific Handbook chapter.  To submit a comment about any aspect or part of the Handbook series, you can use the Handbook Comment Form.

Review a Handbook Chapter: To provide your feedback about a specific Handbook chapter, you can answer the brief survey questions on the Handbook Chapter Review Form.


Technical committees develop and sponsor technical sessions at the winter and annual conferences. Information about their future technical program is discussed at each TC meeting and at the TC’s Program Subcommittee meeting.

ASHRAE publishes papers and transactions from presentations at its conference events. In addition, ASHRAE records most of the seminar sessions from its conferences on DVD. These DVDs are ideal for use at chapter meetings, in university courses, or company lunch and learns. Products available from the most recent conference may be found here.

ASHRAE writes standards for the purpose of establishing consensus for: 1) methods of test for use in commerce and 2) performance criteria for use as facilitators with which to guide the industry. ASHRAE publishes the following three types of voluntary consensus standards: Method of Measurement or Test (MOT), Standard Design and Standard Practice. ASHRAE does not write rating standards unless a suitable rating standard will not otherwise be available. ASHRAE is accredited by the American National Standards Institute (ANSI) and follows ANSI's requirements for due process and standards development. Standards may be purchased at the ASHRAE Bookstore.

TC 6.7 is cognizant (or Co-cognizant) for the following standards:

Withdrawn ANSI/ASHRAE Standard 93: Methods of Testing to Determine the Thermal Performance of Solar Collectors
