How can you ensure thermal comfort standards in your construction project?

To guarantee thermal comfort in your building project, you need first ascertain which standards and guidelines are pertinent to your region, type of building, and design goals. Thermal comfort standards can be found in a variety of places, including industry best practices, national or international norms, and client specifications. The most popular standards, ASHRAE 55, ISO 7730, and EN 15251, define acceptable temperature ranges based on psychological and physiological aspects. It is advisable that you become acquainted with these criteria and utilise them as a point of reference for your study and design of thermal comfort.

Assessing the site's climate and conditions is the second stage to ensuring thermal comfort in your construction project. The building's thermal efficiency and the residents' preferred temperatures are influenced by the climate. For your site, you should gather and examine past and future data on temperature, humidity, solar radiation, wind speed, and precipitation. You should also look for trends, extremes, and seasonal and diurnal fluctuations. Additionally, you want to visit the location and take note of the microclimate elements that influence the temperature, such as vegetation, topography, shade, and orientation. This information should be used to specify the project's design parameters and approaches.

The design of the building envelope, which is the interface between the indoor and outdoor environments, is the third phase in ensuring thermal comfort in your construction project. Controlling heat transmission, air infiltration, and sunshine penetration in a building is largely dependent on the building envelope. The building's purpose, the occupants' behaviour, and the climate should all be taken into consideration while designing the envelope. In addition to optimising the shape, size, and orientation of the openings, you should choose the right materials, insulation, glazing, shading, and ventilation systems for the envelope. The structural, acoustic, and aesthetic features of the envelope design should also be taken into account.

Modelling the building's thermal performance using simulation techniques and tools is the fourth step towards ensuring thermal comfort in your construction project. By using thermal modelling, you may assess how various design choices will affect the building's energy usage and interior temperature. To generate a realistic and accurate model of your building, you should utilise dependable and validated software and data. Then, you should apply the pertinent thermal comfort standards and criteria to evaluate the outcome. Additionally, sensitivity and uncertainty analysis should be done to determine the important factors and characteristics influencing the results related to thermal comfort.

The thermal condition of a building primarily depends on the envelope and the materials used in the construction of this envelope, but before this construction starts, one has to be knowledgeable of the principles of heat transfer, also know the climate conditions of the zone where the structure will be built and finally the physical characteristics of the materials used for the building envelope. With these information, the thickness of walls and floors can be determined along side the optimal orientation of the building and implemented to passively heat/cool the interior of the structure.
