The challenge of decarbonization in the building sector is not limited to new constructions but also encompasses the crucial task of addressing existing buildings. Buildings account for nearly 14% of global emissions, presenting a significant obstacle to achieving sustainability goals. The transformation of existing buildings from "climate liabilities to climate assets" is integral to mitigating their environmental impact and driving progress toward a sustainable future.
Existing buildings contribute significantly to carbon emissions, posing a substantial obstacle to global efforts to combat climate change. Inefficient insulation and poor ventilation lead to energy loss, exacerbating the environmental footprint of these structures. The inefficiencies also result in higher energy costs, impacting the financial well-being of building owners and occupants.
Investing in existing buildings for retrofits and deep energy interventions offers a viable solution to mitigate their carbon impact. Retrofits involving the addition of materials such as insulation, new windows, cladding, and roofing, along with the implementation of high-performance mechanical systems, can drastically reduce energy consumption and resultant emissions by 50% or more. These retrofits enable buildings to capitalize on a decarbonizing electrical grid while lessening the load on that grid. Moreover, retrofits have substantially lower embodied-carbon impacts than constructing new, more efficient buildings.
According to the Rocky Mountain Institute, retrofitting an existing building emits 50 to 75 percent less carbon than constructing the same building new. Strategic material substitutions using carbon-storing materials in deep energy retrofits (DERs) offer the potential for expedited realization of net carbon benefits. Additionally, policies supporting investment in low-embodied-carbon products, carbon-storing materials, and DER solutions can accelerate the transformation of existing buildings from carbon-emitting to carbon-storing entities.
