Drake Landing Solar Community

Actually we do not have an energy problem. All we need are solutions for energy storage as the sun provides us with more energy than we need. That is what the The Drake Landing Solar Community (DLSC) in the Town of Okotoks, Alberta, Canada did – and has achieved a world record with ist first‐of‐a‐kind large‐scale seasonal storage solar heating system.

With an ingenious conception of a heat buffer for a locoal community heat can be provided even in the coldest areas – all year long: by successfully integrating energy efficiency, solar energy, district heating, and energy storage technologies, DLSC is fulfilling 80 percent of the space heating requirements for a 52‐home neighborhood with solar energy.

There was a lot of drilling with holes up to 37 metres deep on a circular area 35 metres in diameter. 144 boreholes spaced 2 metres apart, which work as a huge heating system. During the summer, 800 solar collectors heat up a glycol-and-water mixture kept in this system of underground heating tubes – to store heat for the winter.

The area is now overgrown by a beautiful park. DLSC is en route to achieving its target of 90 percent in the year 2012 and a reduction of five tons of greenhouse gas emissions per home per year.
