Case Study - Single Family Home
Our client owns a 3,200 square foot, two-story single-family home in the metro DC region. The home has an attached garage, was built on slab, has adequate shading, and is roughly 30 years old.
The client was tolerating winter drafts, a master bath that was nearly unusable in winter and a walk-in closet that ran to 100F in summer. Utility bills commonly ran in excess of $300 per month during the heating and cooling seasons (this is well above the regional average).
We completed our inspection and found several items that were available for improvement:
- Critical errors in the installation of existing insulation and equipment
- Absence of insulation and air sealing in areas that require both
- Fire safety hazards related to electrical wiring
- The exclusive use of incandescent lighting
- The presence of significant phantom or vampire loads (idling electronic appliances)
- High-volume water fixtures not providing high-volume performance
The client was able to undertake the corrections we recommended. Utility costs were cut by 34% and return on investment was on the order of 11% or 11 dollars returned each year per $100 invested. As important as economic returns above the long-term market average, we eliminated the drafts, brought the master bath to 70F in winter and the closet high temp. to 80F (the latter without air conditioning supply). Water / public works savings were on the order of 18%.
