The green opportunity: Tackling 37% of global carbon emissions with smart building technologies for
According to the United Nations Environment Programme report, the buildings and construction industry stands out as the leading contributor to greenhouse gas emissions, representing a remarkable 37 per cent of the global total. The manufacturing and utilisation of key materials like cement, steel, and aluminium play a substantial role in this carbon footprint. However, this fact also underscores the possibility of positive change, which may surprise some. Those aiming for net-zero buildings must tackle energy efficiency issues and integrate smart building technologies. Importantly, these solutions are not just futuristic concepts; they are already accessible and ready for implementation.
Over time, the focus of the sector's advancements has revolved mainly around mitigating the "operational" carbon emissions associated with building activities, including heating, cooling, and lighting. Forecasts indicate a promising shift, with operational emissions anticipated to decrease from 75 per cent to 50 per cent of the sector's overall emissions in the forthcoming decades. By 2050, approximately half of the current building stock is projected to remain in operation. Since newer constructions generally exhibit higher energy efficiency, their contribution to overall emissions is expected to be lower. Consequently, initiatives aimed at decarbonisation should prioritise the renovation of existing buildings.
