![]() In contrast, for Sections 6 through 12, the “Cont. Verified” column shall be used to indicate Items verified by the credentialed contractor (or a firm or HERS Rater hired by the contractor). Note that builders are not permitted to verify any Items in Sections 6-12.Ħ. If any Items have been marked “Builder Verified,” then the builder is responsible for these Items and must sign this Checklist. For Sections 1 through 5, the “Builder Verified” column shall be used to indicate items verified by the builder (or a firm or HERS Rater hired by the builder). The person responsible for the heating, cooling, & ventilation design shall be responsible for completing Sections 1 and 2 of this HVAC System Quality Installation Contractor Checklist.ĥ. One Checklist shall be completed for each system and provided to the Rater.Ĥ. If the ventilation system is the only applicable system installed in the home, then only Section 1 shall be completed. All other permutations of equipment (e.g., boilers, mini-split / multi-split systems) and distribution systems are exempt. This Checklist applies to ventilation systems to split air conditioners, unitary air conditioners, air-source heat pumps, and water-source (i.e., geothermal) heat pumps up to 65,000 Btu / h with forced-air distribution systems (i.e., ducts) and to furnaces up to 225,000 Btu / h with forced-air distribution systems (i.e., ducts). ![]() Therefore, this Checklist is not a guarantee of proper ventilation, indoor air quality, or HVAC performance. However, these features alone cannot prevent all ventilation, indoor air quality, and HVAC problems (e.g., those caused by a lack of maintenance by occupants). This Checklist is designed to align with the requirements of ASHRAE 62.2-2010 and published addenda and ANSI / ACCA’s 5 QI-2007 protocol, thereby improving the performance of HVAC equipment in new homes when compared to homes built to minimum code. The numbering corresponds to the original checklist document so some numbers may appear out of sequence.ġ. The footnotes for this measure are listed below. For information on installing HVAC equipment, see the HVAC System Quality Installation Rater Checklist. This page provides the full language for the selected checklist requirement and shows the applicable footnotes describing how to comply however, a full measure guide showing installation information is not needed. Rather, these checklist steps verify that a particular procedure was followed or that appropriate information was used in selecting or sizing equipment. The requirements from the checklist do not involve the actual installation of specific measures. The software is available in a Basic and a Pro version.Builders, raters, and installers use the ENERGY STAR Certified Homes (Version 3.0, Revision 07) HVAC System Quality Installation Contractor Checklist (HVAC/C) to document the sizing and testing of HVAC equipment. appropriate pressure drop on thermostatic radiator valves. It automatically takes into account requirements on authorities for control valves, e.g. ![]() You can also reduce overpressure in circuits by adjusting initial presets of valves. You can size the diameters of pipes, calculate the hydronic resistance for individual circuits, taking into account gravity pressure, resulting from water cooling in pipes and heat receivers. ![]() Many different system types are supported: one- or two-pipe heating, two-pipe cooling, four-pipe heating + cooling, vertical or horizontal distribution, radiator or floor heating, terminal units, flat stations, and (hot) water circulation.Īn important feature of the program is the possibility of placing many sources of heating and cooling in one project, which is used in the design of four-pipe heating+cooling systems. check the capacities of the hydronic balancing in existing systems for renovation purposes. With our software you can make a 3D graphical design of a new central heating, cooling or water system. How can Danfoss SET 365 software benefit you? ![]()
