Energy Efficient Facelifts for Buildings

From “ZEROPrize Winners Showcase Re-Skinning as Energy Efficient Facelifts for Buildings” by Carissa Bluestone:
Re-skinning, essentially putting an entirely new facade on a building, can save an older structure when standard retrofits like installing insulation fail to make it more energy-efficient. There’s no one approach to re-skinning. The winners of the ZEROPrize, a re-skinning award from ZeroFootprint (in conjunction with UNHabitat and others), worked on a variety of structures from a typical single-family house in Toronto to a large bank headquarters in Ludwigshafen, Germany. The former, a 60-year-old bungalow called the Now House, achieved an energy savings of 70% after it was given a new envelope with high-quality insulation and a new roof with integrated solar panels, among other improvements.
The most beautiful project in the winners circle was 355 Eleventh, a small industrial building in San Francisco. Aidlin Darling Architects replaced the original steel cladding with a new skin of perforated, corrugated metal laid over new walls that included operable windows (something the original building lacked). The result is a striking, modern building full of light and natural ventilation that still retains its historic character. The retrofit reduced energy consumption enough to earn the building a LEED Gold designation.
