This document discusses optimizing energy efficiency in buildings. It notes that most of a building's energy consumption is determined early in the design process. Buildings account for around 40% of total energy consumption and 36% of CO2 emissions in Europe. Up to 73% reduction of energy consumption can be achieved through refurbishing existing buildings, as more than a quarter of buildings in 2050 have yet to be built. A new software called A+E:3D allows architects to run energy calculations early in the design process to optimize efficiency according to regulations and receives feedback on options.

2. Did you know that the majority of a building's energy consumption is determined
within the first few weeks of architectural design process?
Buildings account for around 40% of total energy consumption and 36% of CO2 emissions in
Europe
80% of the operational costs of standard new buildings can be cut through integrated design
principles
Up to 73% reduction of energy consumption can be reached through refurbishment of the existing
building stock
More than one quarter of the 2050s building stock is still to be built.
New buildings only account for 1% annually of the existing building stock - refurbishing for energy
efficiency pays off
