Ontario’s ECHO Net-Zero Prefab Home Combines Passivhaus and Solar for Flexible Green Living

by , 09/18/13

The house can generate as much power as it consumes over the course of a year, thanks to 30 photovoltaic modules mounted on its roof. The modules feature high quality mono-crystalline cells which can yield 260 Watts of power per 60-cell module. Each PV module is equipped with a microinverter which allows for per-module maximum energy harvest, which is particularly useful when dealing with harsh and long winters.

Besides using renewable energy sources to achieve an impressive level of sustainability, the house also features walls that use infused expanded polystyrene, which is manufactured without the use of harmful airborne pollutants. The air gap between the polystyrene and the exterior layer minimizes the risk of mold growth and premature timber decay. The house is planned to achieve an R-value (thermal resistance) of 55, which is over twice the insulating capacity of a conventional home.

    What about a nordic style composting toilet? Where’s the water? What about a roof mounted black solar water tank like is found all over the MidEast?
    Good start.
    Lots of room for improvements.
    What about earthquake ratings for California installation?
    Do you provide turnkey services?
    Total price to install after the land is leveled?

    I am totally impressed… I would love to own a home such as this… imagine never having to pay another electric bill.. also thus creating more electricity used to power public places such as hospitals, hotels and senior living facilities without the fear of causing power failures due to over usage.. a very green Idea!!!
