Temperature

The Property Division oversees the heating and cooling of all buildings at Imperial, ensuring temperatures are kept comfortable and safe for students and staff.

In determining standard building temperatures, we balance creating an enjoyable environment for building users, whilst being conscious of our sustainability commitments and not heating or cooling excessively.

When is the heating on?

Most buildings are heated Monday to Friday, 8.30 to 18.00. In order to save energy and reduce our emissions, heating is turned down to a reduced yet safe level outside of these hours and at weekends.

Heating is generally not turned on when the outside temperature is expected to be above 16°C.

What temperature is it kept at?

We aim to maintain 20°C in offices and academic areas (usually within ±2°C).

Air conditioning and high temperatures

Air conditioning is a significant contributor to energy consumption and, as such, our carbon emissions. Institutionally, we generally do not centrally cool our buildings.

In areas where cooling is provided, it's set to a minimum of 24°C (or 22°C in certain specialist areas) with a threshold of ±2°C. Where cooling is provided, building users are asked to be considerate of energy consumption by following sustainability recommendations on air conditioning.

If your work area is experiencing extreme heat, we may be able to provide personalised support. Please contact our team in order to discuss your requirements.

Report an issue

If something isn't right with your heating or cooling, you can contact our team.

If you're experiencing discomfort, please also consider:

• In winter: If your room feels cold, check that windows and doors are closed
• For naturally ventilated rooms: Opening windows is the primary way to adjust comfort
