Energy Efficiency in Buildings

Buildings are the largest energy consumers in the world. They account for around 30% of global carbon emissions, and over one-third of final energy use. This share could double or triple by 2050 if we do not act, as buildings have a long life-cycle that locks in their energy use.

According to the International Energy Agency, energy consumption in buildings needs to be reduced by 80% by 2050 if we want to limit global temperature rise to under 2˚C.

What is Energy Efficiency in Buildings?
Energy efficiency in buildings is a cost-effective way to improve balance sheets while contributing to the climate challenge, by:

  • Producing economic and social benefits. Investing in a 30% improvement in building efficiency can have an internal rate of return of 28.6 % over a 10-year period1. In addition to reducing energy bills, it also increases the value of real estate assets and improves building users’ productivity, health and wellbeing through a better indoor environment.
  • Anticipating regulatory requirements and pushing the energy performance of buildings upward.
  • Reducing and/or eliminating GHG emissions.
