Mini-ZEPH Backyard Cottage


By JGA Consultants and Buck Tide Construction

As a Zero Energy Passive House (ZEPH) this backyard cottage offers a two bedroom, two bath home on two levels. The passion behind this three year collaboration with Catie Chalplan of the Wood Technology Center is to show that a small efficient living space can be healthy (continuous filtered fresh air), comfortable, beautiful and have a level of energy performance that reaches the Net Zero Energy level on an annual basis.

  • The upper level was built over two years by students in wood construction at the Wood Technology Center
  • 2×8 SIPS walls and 2×10 SIPS roof
  • Triple pane Eurotek tilt-turn windows
  • Zehnder heat recovery ventilator
  • Energy Star rated appliances
  • PowerWise energy monitoring system and domestic hot water sourced from a Sanden CO2 heat pump system located in the main house.
  • The exterior of the upper module is sided with Nakmoto cyprus Shou-Sugi Ban vertical siding source from Japan.
