The Guilford Passive House - by Celebration Contracting project in Guilford, CT.

General project overview:

The home sits on a beautiful tidal marsh with distant views of Long Island Sound at an elevation of 47 and will be certified as a Passive House through the Passivhous Institute.  There is 3,045 SF of conditioned space with additional unconditioned area of 265 SF as a solar conservatory off the rear (south facing).  The basement is also unconditioned and has 1,800 SF.  We recently completed our initial wall studs only blower door test and achieved a 0.34 ACH50 – this may actually increase slightly as we decrease the interior volume calculations as we continue to fit up the home with insulation and sheetrock. The PHPP standard is a maximum of 0.6 ACH50 so we will undoubtedly achieve that goal

 

Orientation and Envelope: (windows, insulation, framing)

The home is oriented 12 degrees west of south (true solar south) and fitted with Klearwall windows manufactured by Munster Joinery on Ireland – they are constructed of uPVC and have an R rating of 9.8 and a 5 point locking system that achieves extreme air tightness.  The wall assembly is a 13” double wall with full depth dense pack cellulose that achieves an R-value of 45.7.  Roof framing is 11-7/8” TJI with a minimum 10.5” depth of open cell Demilec Agribalance  4.45 R-value per inch for a finished R-value of 48
