Thousands of buildings will slowly begin to reopen in the coming weeks after a significant period of inactivity. This inactivity does not only refer to people but also to the facilities which are key to a functional and comfortable office area such as boilers, HVAC systems as well as water tanks and associated pipework.
In older buildings, and those with boiler fed heating systems, the sudden loss of demand will undoubtedly affect the HVAC systems. The biggest issue facing facilities and building managers is the threat of legionella from standing water in the pipework. There is substantial guidance on the CIBSE website (Chartered Institute for Building Services Engineers) which offers advice for risk management and system restart which will be a useful tool. It may be as simple as restarting the system at a lower temperature for the first few days or buildings may require the entire system to be flushed out and re-filled to ensure no microbial growth.
To avoid large energy costs, restarting the system at a reduced temperature is the more desirable measure however it is essential that building service engineers and facility managers check with their boiler procedure or manufacturer.
The guidance on the CIBSE website provided by heating system manufacturers is as follows:
Reducing energy costs in the initial few months of building reoccupation will be an important consideration to both large companies and SMEs. The restart is an ideal opportunity to evaluate your baseload energy use during lockdown where you can see what has been consuming energy in the background. This can be done using half hourly data (HHD) if available or from monthly meter readings therefore taking a manual reading as soon as possible will be extremely useful for evaluation.
Businesses should take this opportunity to optimise control systems such as heating, air conditioning or air handling units to determine an operation which will not be based around comfort levels but the best temperature for building fabric and avoid wasted heat. This will not only help to abate microbial growth but will also ensure your ventilation and heating systems are not overwhelmed and reduce energy consumption and costs! Office behaviours and building occupation will change significantly over the next year and therefore the benefits to businesses can be substantial if realised early.
The start up recommendations provided here involve no upfront capital investment and may provide the vital cost savings required to kick start your business or fund your low carbon energy generation projects.
