The green building trends continue to grown in Canada, with 51.6 percent of the space in Vancouver and 51.0 percent in Toronto. Following, Sydney and Melbourne were ,,green" office square footage increase from less than one percent in 2006 to more than 46 and 28.8 percent, respectively. Additionally, Warsaw's "green" office market was essentially non-existent as recently as 2010, but now comprises 21.3 percent of space tracked by CBRE.

So why we should start to build more Greend Buildings?

First of all it has a enviromental reasons: reducing greenhouse gas emissions compared to other major emitting sectors, the emissions savings potential is said to be as much as 84 gigatonnes of CO2 (GtCO2) by 2050 and  the building sector has the potential to make energy savings of 50% or more in 2050.

Global energy efficiency measures could save an estimated €280 to €410 billion in savings on energy spending, which has a huge economical impact.

There is a social benefits as well: Workers in green, well-ventilated offices record a 101 per cent increase in cognitive scores (brain function), employees in offices with windows slept an average of 46 minutes more per night, research suggests that better indoor air quality (low concentrations of CO2 and pollutants, and high ventilation rates) can lead to improvements in performance of up to 8 per cent.

By applying sustainable building strategies, we can maximize both our economic, environmental and social performance.
