“The new Toronto office of the Elementary Teachers’ Federation of Ontario (ETFO) has officially received LEED Platinum Certification, the highest environmental standard possible.“
“The new office also achieved a Canadian first in geothermal heating and cooling, one which has opened up the possibility of retrofitting older buildings with geothermal systems. Whereas drilling to sink geothermal ‘columns’ was only possible before construction began on new buildings, ETFO’s building partners used new technology to bore down 50 storeys from the underground parking garage after a major part of the office had been constructed.
The technology used to achieve this ‘first’ means that older buildings can now be retrofitted with geothermal energy. The system has achieved a 71% reduction in heating and cooling energy for ETFO, and it also shortened the construction time period.”
