Carleton East Apartments, LANHAM, MD
To replace their two aging cooling towers, reduce wasted water, improve energy.
For this apartment complex, EMCOR Services Combustioneer (Combustioneer) installed new high-efficiency boilers, which provided increased equipment reliability, energy savings, and hot water service for residents and staff.
Combustioneer also helped their client take advantage of a Washington Gas rebate program that rewards high-efficiency equipment. By estimating the energy conservation and potential rebates, Combustioneer sped up the procurement process and substantially reduced costs for the client.
Carleton East Apartments needed to replace their 50-year-old boiler units, which were nearing the end of their life expectancies.
Combustioneer installed the following equipment:
- Seven new three-million-BTU, high-efficiency condensing boilers
- A new, energy-efficient plate and frame heat exchanger
By replacing the three 10-million-BTU boilers with seven lower-BTU units, Combustioneer enabled building engineers to bypass individual units for reliable heating and easier transitions between seasons. The higher boiler efficiency during the heating season and improved part-load efficiency throughout non-heating season will provide an estimated annual savings of more than 111,500 therms and $49,000.
The new boilers not only provide energy savings and increased reliability, but they also came with a $150,000 rebate from Washington Gas. Combustioneer is an approved contractor with the Washington Gas Energy Savings Program.
Combustioneer also replaced the existing tube-and-shell heat exchanger with a more efficient plate-and-frame model. The new unit reduces the energy required to isolate and heat boiler water from the domestic water for apartment use.
