Heating & Cooling Load Calculations

Heating & Cooling Load Calculations

Thermal Modelling software is used to calculate the heating and cooling loads of buildings, to determine the required heating or cooling facilities needed to keep the living spaces at a reasonable temperature.

Correctly sizing the heating and cooling facilities for any development will ensure compliance with CO2 emissions regulations and increase the overall energy efficiency of the building.

It is also essential that the correct system be chosen for maintenance purposes, such that a system which is too small is not overrun and breaks down often, or too large with a greater energy requirement than is optimal for the development.

All sources for heating and cooling are considered and a report is generated to show how much heat is required in kW to maintain comfortable room temperature.

This is done by using the dimensions and material data to calculate the buildings heat loss factors on its external surfaces, then other factors such as ventilation can be assessed for their impact.

Ideally in buildings with larger surface areas for single construction elements, those surfaces should be made more thermally efficient to minimise heat load requirements.

External temperature is used as a reference point for heat loss, I.e. the lower the temperature outside, the greater the heat loss potential and the greater the heat load requirement to maintain the buildings comfortable temperature level.

With all this data gathered, it is now possible to calculate the cost of the heating or cooling requirements based on their energy usage, and the carbon emissions can also be determined given what hearing or cooling strategy is used.

We can report and advise on what solutions might be most cost effective, carbon efficient and practical for your developments.
