A returning client came to us after purchasing a historic house in the Belle Mead area of Nashville. The homeowners wanted to transform it into a modernized, high performance home for their family of four. They called on E3 to help think through all of the building envelope details and mechanical strategies. During the renovation process, their 1920’s estate was completely gutted – only two walls and a portion of the roof were preserved – yet the finished product maintains the charm and feel of the original design.

E3 was part of the design team from the very beginning of the planning process all the way through testing and commissioning of the completed project, providing:

  • Fielding questions about new technology
  • Home optimization analysis using computer modeling
  • HVAC load calculations and design
  • Ventilation deign
  • Before and after radon testing and mitigation design
  • An encapsulated attic
  • An encapsulated crawlspace
  • Spray foam insulation and air sealing applied to envelope
  • Commissioning and testing of the envelope, duct work, and system performance
