On top of this, other practical constraints include social acceptance of greener methods, including electricity capacity.
Desk fans help to reduce the perceived temperature by around 2. o.C, but the additional air movement increases the risk of particle movement.
So desk fans are not recommended, except in rooms with good airflow and high air changes.A simple, but effective, approach might well be just to have a relaxed dress code.That way, people can dress according to how warm they feel, which will make them more comfortable, and more productive as a result.. What can building occupiers do for both the environment and energy efficiency?.
Our dynamic thermal simulation enables a data-driven approach which we can use to predict internal temperatures, air flow and occupant comfort in existing offices.It allows us to model scenarios so that building operators can effectively predict threats to occupant comfort.
We can test rectification measures in a simulated environment and understand how they will affect energy bills – before choosing the most appropriate option.. A moment to act.
Once you have planned how to meet the challenges of thermal comfort, now is also the time to do a full MOT of your ventilation, heating and cooling plant.Ideally, new riser space can be formed in such a way that it doesn’t significantly reduce net usable lab space or cause issues with adjacent tenancies (where relevant).
Where this isn’t possible, external ductwork can be considered, however there are other issues such as building appearance and Planning Permission that can make this unfeasible.. Exhausts for fume cabinets, ducted MBSCs, storage cabinets, and LEV (local extract ventilation) will also need to find their way to roof level.With limited riser space this means upper-floor office conversions are preferable, though these tend to be less advantageous from an access or structural point of view..
It is essential roof exhausts have efflux arrangements that ensure discharged fumes get sufficiently away from the building to prevent recirculation into make-up systems or to anyone on the roof or in a nearby building.In the UK, the British Standard has a blanket statement requiring fume stacks be either 3m high or 25% the building height – whichever is greater.
