We all know that building new green buildings is always a hot idea, but experts have been pushing the idea that retrofitting existing buildings with green upgrades provide more environmental benefits. Your first thought may be new = better however, there is now proof that these experts are correct from a report released earlier this year. The report found that it is unequivocally greener to retrofit an old building than construct a new green building, no matter how many high-tech bells and whistles are in the new construction. The report was drawn from “The Greenest Building: Quantifying the Environmental Value of Building Reuse” project which was commissioned by Preservation Green Lab.
Elizabeth Heider, chair of the board of directors at the USGBC said “The thought was in order to build green you have to build new.” However, the report numbers add up in favor of retrofits. The report states:
- It can take between 10 and 80 years for a new energy-efficient building to overcome, through more efficient operations, the negative climate change impacts that come from construction.
- Environmental savings from re-use are between 4 and 46 percent over new construction when comparing buildings with the same energy performance level
- The negative environmental impact of retro green for human health was between 12 and 38 percent less than for new construction
- When it comes to ROIs, retros showed a 19.2% increase in ROI versus 9.9% for new buildings
