WINNER OF TWO
Colorado Green Building Guild
GREEN BUILDING AWARDS, 2014
Best New Green Home - Traveler's Rest Passive House
Certificate Of Occupancy for this 6,800 SF home was obtained in October 2014.
MainStream performed energy modelling and worked with the Architect, Halcyon Design, to optimize the design for Passive House performance. Traveler's Rest accommodates multi-generational living with a large shared space and modest suites. There are 4 independent entrances to each of the master suites and 5 heating and cooling zones. The two-year build included an insulated 30x40 steel shop and access through the 40-acre parcel. The luxurious home is net zero with a 15kW PV array and only uses a 2.5-ton geothermal system for space conditioning. A house this size normally uses 8 tons!!
Final Passive House Certification is pending; the project is officially Pre-Certified through PHIUS.
Most Innovative Green Building - Passivista
This 3688 SF home, with a hot tub, averages less than $92/month for gas and electricity.
How? The innovative design includes appropriate R-values for the climate, good windows (U-value <0.19), with a highly-efficient fresh air system and excellent air-tightness. The final blower door rating broke records in 2012 at 0.23 ACH50. The Passive House fundamentals were well-implemented during design and construction to produce a truly performance-driven building, and not to mention . . . a comfortable home. "I feel spoiled because the temperature never goes below 68 deg F!" proclaims the Owner. The gas useage accounts for the tankless hotwater heater and the 36 kBTU stove, and totaled $347 over 12 months. The electricity totaled $755 and water $283 for the same time period while adding a hot tub and laying sod in the spring.
The overall total for 2013 is $1,386 including all service fees and taxes.
