New Construction > Passive Active Greenhouse

A Passive/Active Solar greenhouse we designed and built in Yellow Point.

 

The roof and South glazing angles and glazing types are optimized for winter and summer growing. Rainwater is collected and used for irrigation.  Heat is controlled and moderated by heat actuated vent openers, solar powered fans, an earth tube heat storage system, thermal mass as well as high pressure sodium lights and an electric fan.  The grow tables are repurposed display tables from a closed down furniture store and the planters are made from cedar that was grown and milled on site.

The green house is built using traditional timber frame jonery and the doors and vents are all custom made in our shop.
