Tip: The following section can be edited by the webmaster as needed. It does not have to be about Whitepapers. You can edit that to be anything. To add, delete or reposition sections of the accordion, use the concentric arrows button in the editing toolbar at the top. When typing or inserting text into an accordion and there is more than one paragraph, you MUST use "shift + enter" between paragraphs. Be sure that you do not accidentally just use the "enter" key to separate the paragraphs. It will look OK but after you publish the page, the text after the 'enter' may no longer be editable.

Research

ASHRAE members have free access to research project final reports. Non-ASHRAE members can purchase research reports for $30 per article from the ASHRAE Bookstore found at this link.

Recently TC 6.8 completed the following project:

1674-RP: RESEARCH TO SUPPORT THE REVISION TO GROUND SOURCE HEAT PUMPS: DESIGN OF GEOTHERMAL SYSTEMS FOR COMMERCIAL AND INSTITUTIONAL BUILDINGS

The objective of this project is to gather updated information from recent ASHRAE research, conduct research in critical areas not adequately addressed (detailed field studies and cost optimization methods), integrate revised industry standards, and identify equipment and technology advances so that the updated GSHP text will be relevant and useful to the industry. Eight existing chapters and eight appendices will be revised. A new chapter on site characterization and an appendix, "Hydro -geological primer for engineers" will be added as requested by ASHRAE Special Publications.
