BS 40102 - A new British Standard on health and wellbeing, thermal comfort, indoor air quality and overheating in buildings is being developed in two parts.

Part 1 – Health and Wellbeing in Buildings - This part will give recommendations for the measuring, monitoring and reporting of the well-being and IEQ performance of an occupied building and the associated building services.

Part 2 - Thermal Comfort, Indoor Air Quality and Overheating - will provide technical benchmarks that address the health and wellbeing issues identified in Part 1, essentially developing a best practice approach to thermal comfort, overheating and internal air quality.

  • IMPACT – Raise standards and give benchmark data to apply to building environments. ISO TC/205 are also looking in this area which also shows well for the air movement industry.
