What is adaptive thermal comfort ?

-
Image
Overview Field studies of thermal comfort have been conducted intensively at various climatic locations to define the range of acceptable thermal environment for air-conditioned and naturally conditioned buildings that led to the development of Adaptive Thermal Comfort (ATC) model.  Research on adaptive thermal comfort revealed a higher range of acceptable temperatures, which depend on climate, building type, behavioral controls, and other similar factors. Field studies have also revealed the role of thermal adaptation to conserve energy in air-conditioned buildings, and this concept is also useful for building design, and operation of naturally conditioned buildings as per the outdoor conditions.  Higher bandwidth of comfort temperature and energy conservation opportunities encouraged researchers to carry out intensive field studies of thermal comfort to propose robust adaptive thermal comfort model. Definition Adaptive principle states that if a change occur...

ISO 7730 for Thermal Environment Evaluation

-
ISO 7730 is an International Standard for 'Ergonomics of the Thermal Environment-Analytical Determination and Interpretation of Thermal Comfort Using Calculation of the PMV and PPD and Local Thermal Comfort Criteria’.  ISO 7730 illustrates methods to evaluate the general thermal sensation and the degree of discomfort for occupants exposed to moderate thermal environmental conditions. This Standard grouped the thermal environment into three different categories namely  Category-A,  Category-B and  Category-C  All there  categories  are described with the help of Table given below.  Category-A describes narrow comfort conditions, whereas Category-C prescribes wider comfort bandwidth (-0.7 < PMV < +0.7). The Standard describes the calculation of PMV and PPD indices for thermal comfort and for local discomfort. The Standard also defines the local clothing habits for indoor comfort and but does not provide information for cl...

EN 15251 for Energy and Thermal Environment Evaluation

-
Comfort standard EN 15251 (version released in 2007) is entitled to ‘Indoor environmental input parameters for design and assessment of energy performance of buildings–addressing indoor air quality, thermal environment, lighting and acoustics.’  The Standard EN 15251 deals with energy performance of buildings as well as indoor environment quality such as thermal environment, indoor air quality, acoustic comfort, and visual comfort conditions to provide more comfortable indoor climate and that is also energy efficient.  Previous research  (Nicol & Wilson conducted study in 2010)   has examined that EN15251 Standard helps building designers to optimise the building energy consumption, considering thermal, air quality, acoustic and visual comfort. Furthermore, studies carried out under SCATs (Smart Controls and Thermal Comfort) research project reveal that this Standard involve  only   European countries for energy and comfort evaluation. SCAT s...
