The E-cube comes in three standard designs from 1400 to 2200 square feet. They include features such as double glazed, argon filled, low E windows exterior sun screens and extremely well insulated roofs and walls. The residence is made out of 8 inch Structural Insulated panels for the walls which provide an R40 value and 6 inch SIPS for the roof with an extra 12 inches of insulation (R60).

The building floor plan provides for good cross ventilation and good solar control and passive heating. The design allows for some greener options such as an upgrade to triple glazed windows, a heat recovery ventilator and photovoltaic solar collectors. And as a recommended finish, the manufacturer recommends a green roof. Rainwater harvesting, dual flush toilets, energy star appliances and LED lighting fixtures complete the deal.

Overall the E-cube looks to be an attractive package for those of you looking for a nice prefabricated residence. There are a few nitpicks with the floor plans that we could bring up (bathroom right at the entrance? access to the furnace from the outside?) but those are details that can be easily fixed.
