Our GC created an in-house construction management and building team within Boulder County as a means of saving tax-payer dollars on the multi-year/multi-million dollar Boulder County Justice Center remodel. When the federal cash grants were made available, solar PV helped green this essential government facility.
See aerial image above showing the solar PV modules that were secured to the TPO rooftop with a customized structural subframe (elevated racking) system that had to be designed strong enough to resist the major wind and snow loads that Boulder is known for.
In 2001, Constructive Alternatives finished building the Johnston Residence on Sumac Street entirely of Insulated Concrete Forms (ICFs) with the goal of simulating their desire for an adobe home in Colorado. Because structurally, adobe wasn't sound in Boulder's more hostile freeze/thaw environment, ICFs were an excellent alternative. The couple loved how their Boulder bungalow turned out looking so similar to the adobe homes found in their native Mexico. They also came to fully appreciate the insulating and acoustical qualities of the ICF construction--particularly as it helped create a tranquil and quiet counseling environment on the lower level, which was designed to be their in-home counseling center for children.
The Boulder Daily Camera featured the Barrett House (North Boulder's first solar/green built home) and the Callahan home (an interesting Earthship near Ward). Barrett Studio Architects Founders David and Betsy Barrett hired Constructive Alternatives for many collaborations, including designing and installing their own home's ICF building system. The Callahans hired Constructive Alternatives to install the solar PV and solar thermal systems and also helped them with the ICF foundation and structural bearing walls that integrated with rammed earth and old recycled tires for the in-fill walls.
