Thermal Imaging (Case Four)
Case Four: Missing Piping Insulation
Buidling Type: 200+ Room Hotel located in Pittsburgh
Equipment Type: Hot water heat.
Complaint: No complaint was made. There was a comment after this discovery that the hall way was always hot year round.
Complaint Type: Energy, Comfort.
Effects: Overheating of adjacent space. Wasted energy.
Cause: This is another instance where an energy audit and building assessment were being performed and having the camera available during a walk-through. I noticed a heat anomaly in a hall way. This seemed out of place, so further investigation was warranted. See image Pair 1 and image pair 2. Thermal imaging indicated that the newly installed (5 years ago) hot water piping had never been insulated. The heat from the piping was radiating to the tile below and subsequently heating the room.

Solutions: Piping insulation was replaced, room comfort returned, and boiler runtime reduced.
