4. User control & alerts
Greater levels of user control are recommended for ventilation and heating systems. Occupants should be able to increase or reduction of ventilation rates as required, maintain acceptable indoor air quality and avoid cold draughts or excessive energy consumption in the heating season. The message is clear; ventilation systems need to be nuanced enough to adapt to the changing demands of schools throughout the year. In fact it promotes greater integration with heating systems to ensure that energy usage is optimised, and greater collaboration with school users to ensure they are aware of classroom conditions (temperature and C02
sensor) and fully trained on how to operate the ventilation systems where necessary. Getting feedback on real-life classroom data is critical to showing how the ventilation system is performing, and finding ways to optimise.
5. Life cycle and maintenance
Continuing with the theme of ensuring schools get the right equipment, there is an emphasis on the life cycle and operational running costs of all systems. Life cycle costs should include energy, cleaning and maintenance costs as systems with low initial capital costs may have unaffordable running costs. Fans, filters and heat exchangers should be easily accessible for maintenance and to inspect for contamination and easy to clean. Manufacturers will need to be more precise on what the total cost of ownership for the end user is, as well as contingency planning for maintenance and repair.
6. Weather testing
As we all know too well, the summer heatwave is only one side of the challenging weather conditions we experience in the UK. Ventilation systems must now be able to withstand winds of up to 30mph without creating a situation where the room becomes pressurised, thereby making doors difficult to open. Additionally, tests need to be carried out on dampers and external louvres to ensure no unwanted leakages take place during rainy periods. A welcome addition to the regulations to ensure that equipment supplied is up to scratch.
