The Earth Rangers Centre located in Woodbridge, Ontario has been awarded LEED Platinum Certification from the Canada Green Building Council, for Existing Buildings (EB).

The Earth Rangers Centre certified LEED Gold for New Construction in 2004, is home to Earth Rangers' Animal Ambassadors and staff and is also a showcase for leading edge sustainable building technologies that reduce energy, water and resource consumption, while also maintaining the highest levels of functionality and comfort for occupants and tenants. The Earth Rangers Centre is proof that a building that was constructed to green building standards can also be operated even more sustainably than originally designed.

"I would like to congratulate The Earth Rangers Centre for becoming the highest rated LEED for existing buildings project in Canada. This is the first time ever that the CaGBC has certified a building initially as LEED Gold for New Construction, and then seven years later as LEED Platinum for Existing Buildings: Operations and Maintenance," says Thomas Mueller, President and CEO of the Canada Green Building Council.

"It is key for LEED certified buildings to not only achieve this high level of performance, but maintain it as well. Earth Rangers took this a step further by exceeding the performance targeted under their initial certification. This project sets a benchmark in Canada that any building owner can follow to create lasting dividends for the environment and their pocketbook."

Achieving a score of 92 of a possible 110 points in the rating system, The Earth Rangers Centre is currently the highest scoring LEED EB building in Canada. The Centre features technologies such as:

  • Solar photovoltaic generation
  • On-site wastewater treatment
  • Earth tubes
  • Solar hot water
  • Stormwater control
