Following the recent Future Buildings Standard consultation, the Building Controls Industry Association (BCIA) is urging a new Parliament to work with it to prioritise the widespread adoption of Class A building controls in new and existing non-domestic buildings across the UK.
The Association explains that The Future Buildings Standard regulations aim to ‘provide a pathway’ to highly efficient non-domestic buildings that are ‘zero carbon ready’. With sustainability a major focus for the building controls sector, and the BCIA aiming to promote the use of controls as key to the operational efficiency of buildings, the organisation has submitted its recommendations during the recent consultation, and is calling on a new Government to consider the evidenced impact that building controls and automation can have.
One of the biggest factors affecting the Future Buildings Standard is the Part L Regulations, which focus on the conservation of fuel and power in buildings other than dwellings. With this in mind, the BCIA has recommended that guidance for the installation of Building Automation and Control Systems (BACS) based on heating, ventilation, and air-conditioning (HVAC) output should be changed to a mandatory requirement for HVAC systems above 180 kW to decrease to 70 kW between 2025 and 2030.
The Association says this will encourage compliance with energy efficiency and carbon standards. It said: “In fact, creating a mandatory requirement will accelerate the uptake of BACS, leading to a reduction in carbon emissions and energy usage.” The BCIA estimates that a requirement to install Class A BACS in commercial and public buildings with an HVAC output over 180 kW could save 16.9bn in energy bills and 39.6 Mt of CO2e by 2040.
The Association is also advocating inclusion of an occupancy-based Class A controls strategy for new buildings across all necessary building services, ‘to drive high levels of energy efficiency’. Additionally, it says, heating controls should be part of a wider controls strategy to support all heating, ventilation, and air-conditioning systems within a building.
The BCIA said: “With around 80% of current UK buildings still likely to exist in 2050, the retrofit market is crucial to ensure Net Zero targets are achieved, yet a black hole exists in current UK policy. The BCIA strongly believes in updating Building Regulations with a regulatory timeframe for the mandatory installation of Class A BACS in new and existing buildings, including a clear end date.”
The BCIA has also recommended reference and scoring for automatic demand control or networked room automation. This is due to smart controls being able to deliver automated optimisation through a series of functions, such as facilities management, consumption prediction, demand response, energy storage and equipment maintenance.
It said: “Occupancy demand-based controls for heating, cooling, and hot water parameters should also be considered, especially as heating and hot water account for a large amount of energy consumption in non-domestic buildings. Occupancy-based controls often result in lower energy use and a reduction in user energy bills.”
The Simplified Building Energy Model (SBEM) is a calculation used to demonstrate the energy performance of new and existing non-domestic buildings. The BCIA wants clarification on how building controls are scored within SBEM. It added: “In fact, the technology and scoring are not currently aligned with a Class A level of controls, which have a significant energy and carbon saving potential.”
Following the General Election on 4 Jul, the BCIA is inviting the sitting Government to meet with the Association and its members to give MPs / Ministers ‘a detailed understanding of how building controls are perhaps the most valuable tool in the box that will, if integrated more clearly in UK policy, make a significant and measurable contribution towards UK PLC’s targets in driving down energy consumption and achieving Net Zero’.
