Built for cold
27th November 2018
CIBSE highlights one of the most challenging aspects of overheating for the UK. The fact is, UK buildings were constructed more with cold temperatures in mind.
As CIBSE points out, this means we end up with lightweight, highly insulated buildings that ‘respond poorly in the summer’.
And older buildings don’t fare much better as they are likely to be difficult to ventilate and offer little in the way of solar gain reduction.
For building services professionals, increasingly hot summers will mean that building owners and managers are turning to them more for help with internal heat reduction.
However, we can’t just add more cooling technology into buildings. That simply compounds our climate problems by requiring more energy use and adding CO2 to the atmosphere as a result.
Energy efficiency challenge
The challenge is not simply reducing heat, but doing so in a highly energy efficient way. This means ensuring that clients are using the most up-to-date technologies that comply with energy efficiency legislation.
There are also important options to consider such as heat recovery, which can take ‘recovered’ heat from occupied spaces and apply it to water for domestic services, for example.
And offering smart kit – that has built-in controls that help users cut energy waste, while optimising system performance.
Encouraging end-users to re-think set points should also be on the agenda. If outside temperatures are rising to 28°C, then an internal temperature of 21°C actually feels too cold to many occupants.
Letting indoor temperatures rise a little higher, while controlling humidity, keeps occupants comfortable and energy costs lower.

- Is air conditioning expensive to run?
Modern air conditioning systems are very economical to run. All systems are now fitted with variable speed inverter compressors, which will increase or decrease their speed and output according to the room or building demand. MJD can supply accurate running costs when we design a system for any room or building.
- Is it necessary to obtain planning permission before having air conditioning installed?
Before any air conditioning is installed MJD would advise that you contact your local authorities or planning department and discuss the proposals with the relevant department.
