Chisholm Place

2014-05-16 10.55.27It’s nice to make a big splash as a new design/build firm in the competitive, central Virginia custom homebuilder market. How about with an award-winning home that earned no fewer than five advanced building certifications? This is exactly what Daniel Ernst at Promethean Homes has done as a follow up to his own family’s “Passive Bauernhaus.” This home on Chisholm Place in Charlottesville is a 2014 Housing Innovation Award winner from the DOE Zero Energy Ready Home program in the Custom Builder Category. Think Little assisted with building enclosure specifications, energy modeling, HVAC design, and building commissioning. Have a look at the write-up for all of the award winners here and check out constructions photos here.
