The Energy Centre
The 2,500 square foot Energy Centre building for the Drake Landing
Solar Community (DLSC) is the heart of the district heating system. Located
in the corner of the community park, it houses the short-term heat storage
tanks and most of the mechanical equipment such as pumps, heat exchangers,
and controls. The solar collector loop, the district
heating loop, and
the borehole thermal energy storage loop pass through the Energy Centre.
Approximately 70 percent of the floor space is filled with two large, horizontal, insulated water tanks, each 12 feet in diameter and 36 feet long. The water temperatures within these tanks are stratified to improve the overall efficiency of the system.
The front room of the Energy Centre contains the pumps, valves, heat
exchangers, expansion tanks, and other equipment necessary to operate
and control the energy system.
Stratified Short Term Thermal Storage (STTS) Tanks and Solar Collector Loop

STTS:
- 2 – 120 m3 steel tanks.
- Epoxy lined for 100°C water.
- Horizontal baffle to encourage stratification and plug flow through upper and lower chambers.
- The storage medium is water.
