“Sustainability means a lot to LABS Tower. Heat pump technology is highly energy efficient as it uses renewable energy from the outdoor air to drive the heating/cooling process. This technology delivers high output for low input, leading to a direct saving in CO2 emissions and running costs.”
“Living in a Mediterranean climate, with temperatures reaching in excess of 40˚C, especially given that LABS Tower is a glass building, it is imperative to us that the air conditioning system installed works seamlessly, efficiently and quickly, all of which the Hitachi HVAC system does effectively.”
Frank Stravrou, COO of LABS Tower
