Confluence Architecture & Sustainability was the HERS raters for this home. The HERS is an outstanding -10! The negative means is actually beyond net-zero, it is net-positive. As in, the occupants of this home should never have to pay for heating, cooling, lighting or hot water. Attention to detail got this house crazy air tight. Even with salvaged windows and doors, Steven was able to get this down to .69 ACH50. I’m sure it would have bested Passive House requirements (.6 ACH50) if not for the less-than perfect windows and doors.
Congratulations Steven and Bailey- you have a beautiful, high-quality home. Here are a few teaser photos…
USGBC Colorado honored the Marble Distilling Company design for its exceptional implementation of sustainable technologies with a 2015 Commercial Real Estate Award. The distillery’s integrated systems approach utilizes the heat from the distilling process to heat the distillery, tasting room and Inn as well as recaptures that heat and water for utilization in the distilling process and for domestic use. With these measures, the building is 85 percent more efficient than local code requires. Confluence Architecture is honored to be part of a great team that made this possible. Congratulations to Marble Distilling Company,Energy and Sustainable Design and the whole team! Read more here.
Confluence is proud to have provided energy and sustainability consultation services for Habitat for Humanity in the effort to provide the Lavender’s with a home with very small monthly utility bills. Below is a TV news and a newspaper story about the Lavender home.
In the remodel of KDNK Carbondale Community Access Radio’s building we converted the sealed attic into a ventilated attic. This allows us to raise the insulation level to R49. Typically, adding ventilation to an attic that originally had none includes either; cutting in gable vents, cutting in several thru-roofing vents or cutting in ridge and soffit vents. Thru-roofing vents, ridge and soffit vents are expensive and they required cutting through perfectly good roofing to install. The building did have a window in the gable that could be converted into a louvered vent, but cross-ventilation was still a problem. The solution came from a fortuitous coincidence. The building was once occupied by the international solar technology educators; Solar Energy International. SEI had left a couple of old solar panels in the attic that just happened to be exactly half the height of the gable window. I realized that two solar panels and two 24×24 louvered vents would fill the space left by the window’s removal. Two solar panels would provide more than enough power to run a DC fan large enough to vent the attic for moisture reasons- plus the fan could lower the temperature of the attic in the summer! This is what it turned out like (paint to come in the spring). The controls are 120 AC single-pole cooling thermostat and dehumidistat wired in parallel; so the fan comes on if it gets too humid or too hot.
Another project benefiting from the Confluence Architecture summer of service is the KDNK community radio station. Mark (as a board member) has been assisting KDNK with plans to upgrade its building. A project the whole Confluence team volunteered for is the design and construction of record shelves to get KDNK’s extensive vinyl collection out of the attic and next to the studio.
Confluence Architecture has been donating a day a week to community architecture work this summer. One beneficiary of this work was the SportPlex park in Carbondale. Confluence Architecture worked with the Town of Carbondale, RE-1 school district, Rich Camp Landscape Architect, and Carbondale Commissioner Elizabeth Murphy to update a disused playground and a bath storage building into a lively multi-use sport and play center. Confluence Architecture headed up the remodel of the bathroom and storage building. Our design brought the bathroom up to code, added heat to a previously seasonal building, and increased lighting and heating efficiency. Phase 2 will reside the building and possibly include design charettes with the middle school to get students involved with the new look. The SportsPlex phase one broke ground the last week of July.
