The Ruby House is a modern and sustainable home located in the Avenues in Salt Lake City that is currently awaiting certification from the Passive House Institute. The site of the home was an empty lot bordered to the north by a stately 2-story Victorian and to the south by a bungalow. The new home not only had to fit within the context of the neighbors and pass historic planning approval, it also had to be sustainable.
At first, Dave Brach of Brach Design Architecture thought it would be impossible to create a passive house without a good sunny, southern aspect, but after some serious design work, they put together a plan to create an energy efficient home. The home is so efficient in fact that it is 3 times tighter than PHIUS standard minimum and 50 times tighter than average home construction. The blower door test measured .26 air changes per hour at 50 Pascals of pressure (.26 ACH50).
