Introduction:

Thermal comfort is defined in British Standard BS EN ISO 7730 as: ‘that condition of mind which expresses satisfaction with the thermal environment.’ There is no absolute standard or index of parameters of thermal comfort. This is not surprising, as humans can and do live in a range of climates from the tropics to high latitudes. So the term ‘thermal comfort’ describes a person’s psychological state of mind and is usually referred to in terms of whether someone is feeling too hot or too cold.
Thermal comfort is very difficult to define because you need to take into account a range of environmental and personal factors when deciding what will make people feel comfortable. Perceptions of this environment are affected by air temperature, radiant temperature, relative humidity, air velocity, activity and clothing. More general definitions of comfort include a sense of relaxation and freedom from
worry or pain. These factors become parameters where human perception of the thermal environment is concerned.

 

Objective:

The objectives of this project are:
a) To identify and define the principles of heat transfer in relation to building and people
b) To understand what is thermal comfort and discuss factors relating to thermal comfort
c) To analyze the effect of thermal comfort factors in a person and in a space
d) To be able to criticize design of the space in terms of thermal comfort by referring to MS1525 UBBL.

 

 

Learning Outcomes:
To be able to understand the general principle of heat transfer: 
1. Identify environmental conditions related to site conditions, climate, etc.
2. Explain the effects of the sun on the thermal performance of buildings
3. Explain the effect of insulation, thermal mass and air movement on thermal performance of buildings.
4. Infer how different building material (K-value, u-value, r-value) has different effect on heat gain or thermal environment in a given space

 

 

 

-Initially, we fulfil the aim of this particular research in a group of 5. Site location is required in implementing the study according to the human perception of comfort level. Nevertheless, we have chosen 174P, Jalan SS15/8, My Place Apartment, Subang Jaya, 47500 Wilayah Persekutuan as our site.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

-We used data logger to collect a series of readings for the temperature and humidity of indoor and outdoor spaces as first step for our research. After getting all the data required ready, we used these data collected to plot charts and fulfil the requirements of this project which included identify and define the principles of heat transfer in relation to building and people, understand what is thermal comfort and
discuss factors relating to thermal comfort, analyse the effect of thermal comfort factors in a person and in a space and criticize design of the space in terms of thermal comfort by referring to MS1525 and UBBL.

The tropical climate in Malaysia is consistently hot and humid throughout the year where thermal comfort zone is between 27.6 to 32.1°C and the relative humidity of thermal comfort is varied from lowest 60% to the highest 75%.

In a nut shell, there are more pros than cons via the objective of the study as we could understand the procedures of building design’s effects in relation to not only human comfort level but also quality of space. On the other hand, we also studied the issues which are vital and greatly affect the quality of space which encompassing influences of site context, sun path direction, ventilation, types of insulator and building materials. All these factors are taken into account as they considered as prior in designing future buildings which suits human comfort and also blended with our beautiful Mother Nature.
