CarMic 1954: A Case Study

UNDER CONSTRUCTION! The CarMic Residence is a Net Zero, Foam Free renovation to a historic 1954 mid-century modern stone house in Catonsville, Maryland.  It also happens to be the home of Carri Beer, architect and permaculture designer and Associate Principal at Brennan + Company, and her husband, Michael Hindle, an energy and building science consultant at Passive to Positive.

Holistic Sustainability is the guiding philosophy of this home renovation in Catonsville, Maryland. We are looking at every aspect of our built, economic, agricultural and ecological environment and how the decisions we make affect it. We are taking into consideration our impact on the site, efficient use of water resources, healthy indoor air quality, efficient material and resource use, and aggressive energy use reductions using the Passive House Institute’s model and technologies.

deep en·er·gy ret·ro·fit  is a whole-building analysis and construction process that uses “integrative design” to achieve much larger energy savings than conventional energy retrofits. Deep energy retrofits can be applied to both residential and non-residential (“commercial”) buildings. A deep energy retrofit typically results in savings of 30 percent or more, perhaps spread over several years, and may significantly improve the building value. (wikipedia)

ze·ro en·er·gy  is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site. (wikipedia)

per·ma·cul·ture is a system of agricultural and social design principles centered around simulating or directly utilizing the patterns and features observed in natural ecosystems.  (wikipedia)

ho·lis·tic is characterized by comprehension of the parts of something as intimately interconnected and explicable only by reference to the whole. (dictionary)
