Low-Energy Retrofit
This National Folk House, located in Sewickley, Pennsylvania, suffered from poor energy efficiency and inferior performance. As an aging structure, with minimal insulation and significant air infiltration, this home was a prime candidate for a high-performance retrofit, one that would reduce energy usage, increase thermal comfort, provide superior acoustics, and return value to its owner by lowering utility costs.
To analyze energy consumption, heat and moisture transfer, and hygrothermal behavior, Studio St. Germain used energy modeling software for precise calculations and converted the subsequent data into an effective program within budget considerations. An exterior wall assembly provided an airtight envelope, improving insulation and raising comfort levels from season to season. In addition to conserving energy and minimizing costs, this retrofit eliminates mold growth, giving the program an essential element of high-performance design: a healthy environment that underscores the well-being of its occupants.
Redesigning the facade–giving it a clean, classic look–added an aesthetic component to the livability element of a retrofit primarily focused on energy efficiency and returning value to its owner.
