all valves, sensors, glycol taps, with adequate isolation valves for servicing each component. • Check the expansion tank pressure during installation because the label may not be correct. Make sure the pressure port is available for future maintenance testing. • A preconstruction meeting with the plumbing contractor and designer should emphasize the importance of equalizing the pressure drop through each circuit/tank to ensure balanced flow. Commissioning and Operation Recommendations • Encourage the owner/operator to observe typical operating temperatures and system pressures so that problems can be identified if observed temperatures are out of the normal range or a leak occurs. Recommendations for Future Projects • The construction team should include a knowledgeable person with solar control experience to verify proper flows, temperature differences, and quantified solar performance. • Have a sun screen (tarp) available for the collectors so commissioning work can be performed during the daytime by “turning off the sun.” • Educate the owner/operator to maintain clean collectors and provide them a list of troubleshooting recommendations. Request the owner to record operational problems with date and time. • Snowy climates should include snow removal instructions to prevent lost collection days. • Don’t let the joy of contributing to a great cause overshadow the need to allow sufficient time for good design, product submittals, sequential construction, and thorough commissioning. • If future chapter sustainability projects are automated and live Web data are available to all ASHRAE members, the collective knowledge gain will be beneficial to our industry. • The chapter host committee and Board of Governors should appoint a sustainability project committee with a strong chair, clear lines of authority, deadlines, monthly reporting, technical review, and fundraising to implement the project. • Allow at least a full year from project inception to completion. We hope the detailed report of our experiences will be beneficial to others as they embark on future solar projects. We encourage readers to look at the chapter Web site (www. utahashraesolar.tzo.com) and provide comments or recommendations for a collective learning experience.
