UDATE:  I bought the Foobot, and it will go into our new homes to see if the initial air quality is acceptable.

Low Energy Carriage House Under Construction

After a painfully long permitting process, GBID's "Tandem House" at 2268 S Acoma (off the alley) is under construction.

Design Highlights:

1.  Double stud "Shirley Wall" construction to meet superinsulation goals.

2.  Insulated forms for stem walls.

3.  No natural gas needed for the house.

4.  Heated and cooled with one ductless minisplit heat pump.

5.  Passivhaus air tightness goal, (0.6 ACH 50)

6.  Fluid-applied Vapor Permeable Air Barrier.

7.  Grid tied PV system for net zero yearly energy usage.

8.  Induction range for cooking.

9.  Ductless heat recovery ventilator.

10. Ventless heat pump clothes dryer.

11. Complies with Denver's new Tandem House zoning form.  The home can be legally sold seperately from the home in front.
