 # Energy Efficiency

Summers are getting hotter; winters are getting colder. This affects a building’s energy consumption, both in terms of heating and cooling. In fact, still 70% of a building’s carbon footprint comes from Operational Carbon emissions – energy consumed to heat and cool down buildings while in use. Highly insulated windows, doors and façades play a huge role in ensuring a project’s energy efficiency during its operational lifetime.
