Approximately 80% of commercial buildings operate at a Class C energy efficiency level due to outdated construction regulations, with only one in five adopting Building Management Systems (BMS). The UK construction industry aims for net-zero by 2050, prompting a transformation based on efficiency, sustainability, and decarbonisation. The incorporation of advanced controls in BMS, like Demand Control Ventilation (DCV), proves pivotal in achieving significant building performance. DCV, responsive to real-time demands, ensures efficient ventilation, reducing energy costs and improving indoor air quality. Despite the potential for up to 30% savings with DCV, the UK lags in smart control technology adoption, necessitating a shift to future-proof buildings for sustained efficiencies.
