How do you get thermal comfort in buildings naturally?

The consequence of adaptation is that thermal comfort can be achieved in warm climates, without air conditioning, by using natural ventilation, solar shading and intelligent building design. This allows significant reductions in energy use (see section 5.6.

What factors influence thermal comfort in and around buildings?

The main factors that influence thermal comfort are those that determine heat gain and loss, namely metabolic rate, clothing insulation, air temperature, mean radiant temperature, air speed and relative humidity. Psychological parameters, such as individual expectations, also affect thermal comfort.

How thermal comfort can be maintained in a building?

Air tightness and ventilation An airtight envelope, together with natural or mechanical ventilation, can control the indoor thermal environment by managing the air exchanges with the outside.

What is thermal comfort in buildings?

How does age affect thermal comfort?

There is a lack of studies that describe the effect of aging on thermal comfort and productivity during a moderate temperature drift. The results indicate that thermal sensation of the elderly was, in general, 0.5 scale units lower in comparison with their younger counterparts.

What’s the minimum number of people who can be thermally comfortable?

Thermal comfort is difficult to define because it needs to account for a range of environmental and personal factors in order to establish what makes people feel comfortable. HSE considers 80% of occupants as a reasonable limit for the minimum number of people who should be thermally comfortable in an environment.

How is the thermal comfort of a building controlled?

Thermal comfort can be controlled or adjusted by a number of different measures: Environmental monitoring and control (automated or user-controlled systems, active systems such as heating and cooling and passive systems such as shading).

What happens when people are dissatisfied with their thermal environment?

When people are dissatisfied with their thermal environment, not only is it a potential health hazard, it also impacts on their ability to function effectively, their satisfaction at work, the likelihood they will remain a customer, and so on.

What are the factors that affect thermal comfort?

Other contributing factors can include; access to food and drink, acclimatisation (this can be more difficult where there is a high outdoor-indoor temperature gradient) and state of health. In addition, thermal comfort will be affected by whether a thermal environment is uniform or not.
