And the power of PHPP and WUFI - Passive are available to LEED practitioners regardless of whether they choose to pursue Passive House levels of performance. (hammerandhand.com)
HVI has no testing protocol for sound levels, and it is known that Passive House levels of insulation, triple glazed windows and excellent air sealing result in very quiet buildings where mechanical system sound levels can adversely affect occupant comfort. (nypassivehouse.org)
Next we modelled our high performance envelope scenario to see what would be required for compliance if using a boiler and found that near passive house levels of insulation and airtightness would be needed for all three house types, with U-values of 0.13 for opaque elements, 1.2 for windows and doors and an airtightness of 1.0 m3 / h / m2).
