Thermal Comfort is defined in British Standard BS EN ISO 7730 as ‘that condition of mind which expresses satisfaction with the thermal environment.’ The term describes a person´s psychological state of mind and is usually referred to in terms of whether someone is feeling hot or cold.
There are six factors that affect thermal comfort which are both environmental and personal. The Environmental factors are air temperature, radiant temperature, air velocity and humidity. The personal factors are clothing insulation and metabolic heat.
The purpose of this issue is to ensure that appropriate thermal comfort levels are achieved through design and controls are selected to maintain a thermally comfortable environment for occupants within the building.
We support our clients with an integral dynamic thermal study, which provides information about cooling and heating loads, control strategies and risks generated by overheating. This type of model enables overheating risks and controls strategies of occupied spaces. An occupied space is a room or space within the assessed building that is likely to be occupied for 30 minutes or more by a building user.
In ECOstudio XV® LTD we use the latest IES Virtual Environment software to study Thermal Comfort conditions in occupied spaces.
In BREEAM 2014 there are 3no potential credits including thermal modelling, adaptability for a projected climate change scenario and thermal zoning and controls.
