In my spare time 😉 I’ve been working on a design for an urban Passive House. The design is meant to fit a standard size east-west facing lot. The floorplan offers a first-floor bedroom and bath, as well as an open kitchen, living, and dining area. The second floor offers a flexible layout that can be configured to hold up to 3 bed rooms, 1 bath, and a common room. This urban Passive House works either with or without a basement. Depending on the configuration, it offers between 1,675 and 2,475 usable square feet.
The roof is designed to hold solar-thermal panels that face due south at a 55 degree angle. It also offers plenty of south-facing real estate for PV panels. Ultimately, this Passive House is designed to become a net-energy positive building, e.g. it makes more energy than it consumes and pays its inhabitants by selling excess energy to the grid.
The garage building mimics the main building’s roofline. The main body of the house would be stucco, the gable-ends lap-siding. The roofing is standing-seam metal. The trellis on the south-facade shades the windows below in the summer months. It offers the potential to grow vines on it. Additional solar panels could be located on top of the trellis if so desired.
It’s a work in progress fresh off of the virtual drafting table.
Which software are you using to calculate energy loads?
