Strategies to Reduce Carbon Emissions in Existing Buildings
By Tom Grimand
When Smart Cities are discussed, more emphasis is always placed on the “ground up” phenomena, and not on our existing cities and buildings.
Today’s technology keeps existing buildings continuously retro-commissioned to ensure energy efficiency and low carbon footprint is maintained through new sustainable construction even after the buildings are commissioned.
Why all the concern?
By 2030 more than 60% of commercial floor space will be in buildings built prior to 2008, and will be the largest contributor to global carbon emissions, accounting for about 40% of the world’s total carbon footprint.
- The largest energy and carbon saving potential will be in existing buildings through retrofit and renovation.
- Potential economic savings in existing commercial buildings is between 10% and 20% of current energy use.
