Residential Architecture: Low Energy House MZ by Calderon-Folch-Sarsanedas Arquitectes: “..spanish practice calderon-folch-sarsanedas arquitectes refurbished a 94 square-meter house built in 1918 in only 120 days, to improve its energetic and acoustic comfort. the ‘low energy house MZ’ posed three challenging parameters: it’s northeast orientation, a small budget, and the client’s need to inhabit the dwelling as soon as possible. the components of the house are prefabricated, saving money and allowing the main timber structure, facade and roof to be assembled in only a few days using a numbering system like a toy set..the biggest changes made to the existing structure are the centrally located skylight and large sliding door connecting to the long garden. the openings provide solar gain in the winter and natural ventilation in the summer, as well as illuminate the primary space and reduce the need for artificial lighting. the walls, made from structural timber frame oriented-strand-board (OSB) panels are insulated with natural sheep wool and wood fiber boards, and integrate a dual flow ventilation system with 88% heat recovery. natural larch planks constitute the facade, while heat treated pine makes up the roof and three-ply panels compose the interior cupboards. the overall result is a ten-factor rehabilitation, lowering the residence’s energy need from 171 kwh/m2 to 17 khw/m2..”  Interesting interior volumes; indoor / outdoor sensibility; low energy renovation..
