Retrofit Existing Buildings - Save Energy
Manufacturing Plant - Boiler Retrofit
FACILITY: Clothing Manufacturing Plant - Chicago, IL
PROBLEMS:
- Old gas-fired boiler system was expensive to maintain and operate.
- Higher gas bills and increased operating costs reduced company profits.
- Uneven heating throughout the 126,000 sq. ft. building.
- Very cold dock door areas caused worker complaints.
- Poor winter/summer ventilation.
SOLUTIONS:
- Local heating contractor recommended and installed Thru-Wall, Cambridge Blow-Thru® Space Heaters around the perimeter of the brick building.
- Cambridge included this facility in their unique Building Study Program where customer gas bills are collected and loggers are installed to monitor temperatures throughout the building.
RESULTS:
- Fuel usage declined 62%.
- Cambridge heaters required much less maintenance.
- Warm, balanced temperatures were achieved throughout the building, even at the dock doors.
- Improved ventilation and indoor air quality.
- Lower gas bills and lower maintenance costs resulted in a 2-year payback. After that, the savings went straight to the bottom line to increase company profits.

Retrofit Existing Buildings - Save Energy
Distribution Center - Air Turnover Retrofit
FACILITY: Distribution Center - Columbus, OH
PROBLEMS:
- The existing large air turnover heating system created employee complaints in their 4-year old, 40 ft. tall, 340,000 sq. ft. building.
- Extremely cold dock conditions.
- Hot, uncomfortable upper mezzanine level during the winter.
- The 4 large indirect-fired heating units occupied valuable floor space.
- Very noisy system.
- High operating costs because this large heating system was "running continuously."
SOLUTIONS:
- Retrofit their building with a more effective and efficient Cambridge Heating System that consisted of 5 suspended Blow-Thru® space heaters above the dock areas, which despite their small size are capable of heating the entire building.
