Building Science Project 1 -Case Study: Analysing passive design strategies

 

 

Passive design does not require mechanical heating or cooling. Buildings that are passively designed take advantage of natural climate to maintain thermal comfort.

Incorporating the principles of passive design in building:

* Significantly improves comfort

* Reduces or eliminates heating and cooling bills

* Reduces greenhouse gas emissions from heating, cooling, mechanical ventilation and lighting.

Building envelope is a term used to describe the roof, walls, windows, floors and internal walls of a building. In a tropical climate, the envelope should controls heat gain and exclusion of rainwater. Well-designed envelopes maximize cooling through air movement and exclude the solar radiation. The fundamental principles of passive design are relatively simple and can be applied to various climate zones, house types and construction systems.

 

The objectives of this project are the following which was fully met:- 

* To identify and define the principles of heat transfer in relation to building and people

* To understand what is thermal comfort and discuss factors relating to thermal comfort

* To analyze the effect of thermal comfort factors in a person and in a space

* To be able to criticize design of the space in terms of thermal comfort by referring to MS1525 , UBBL, GBI and Green Mark standards.

Does building science helps me in any others ways ? Yes. Below is my studio board and Explanations)

 

 

In my group i was assigned with softwares programs and boards. Software that I learned to use was revit, vasari and ecotect. At first it was quite hard but gradually i could use it easily. I believe that sunpath diagram is a great way helping to design my building for studio, the reason behind which i have used it for this semester designs and will use it for the next semesters to come. I am proud to say that I could do the sunpath diagram, wind pressure and windrose all by myself and during which i helped my groupmates in learning how to operate the softwares so that they could use it too. Those software definitely helps us in undestanding whether our design strategies are correct or not. As shown below for my studio boards, i was able to incorporate my skills on sun shading as well as windrose to provide myself with a strong backup on explaining why my model was designed in such a way. It also helped better in verbal presentation where i could provide intellectual building science knowledge thus making my work more presentable.
