ABSTRACT

This study aims to evaluate heat gain potential of different building components, such

that the decisions can be made for solar passive optimizations, for sustainable

architecture in a particular Composite climatic type, with a particular occupancy of a

school building.

Aim

To find the most sustainable building system in a school environment by analysing

different components of a school building on different parameters of sustainable

architecture in relation with Solar passive architecture and natural ventilation for a

taken set of climatic parameters.

Objectives

• To compare and analyse the school building design elements identified and

develop an understanding of performance / requirement varying with Building

orientation and construction material change.

• To develop a hierarchy of factors/parameters based on the findings.

• To evolve a standard set of classroom performance enhancement solutions

with reference to a base case scenario for Composite Climate.

Chapter 1, Introduction, is a brief Introduction of the topic explaining aim,

objectives, scope and methodology which have been followed in this research.

Chapter 2, Literature Review and Research Methodology, is the review on the

topic and describes the books, research papers, reports, BIS codes that have been

helpful in the analysis, along with the brief summary of each, the data has been

identified which is used as information or database for simulations and data analysis.

Chapter 3, Materials and Methods

3.1, Composite climate, this part identifies solar-passive performance evaluation

approach with the identification of shading optimization & other factors, which deal

with the heat gain/loss in a building in relation with form, space and location.

3.2., Implication of Climate on Building Design

3.3, Elements of Building Form. This part details out the Effect of Building Form on

heat gain in a building. Factors affecting decision of building form have been

iii

discussed along with the variation in heat gain due to varying building form. The

effect of the neighbouring buildings has also been analysed.

3.4,Solar Radiation and Heat Load Analysis Methodology

3.5, Solar Passive Optimization

This part deals with the function of openings and the heat gain through

openings for building design, Heat Gain for various Aspect Ratios of openings.

3.6, Tree Shade and Solar Radiation

This chapter illustrates the development of a tree shade chat with the help of

Shading analysis of spherical surfaces.

3.7, Vertical and Horizontal Shading Device Optimization

this part focuses on the maximum Solar Energy utilization, with identification

of optimum values of HSA &VSA for shading devices in preferred

orientations.

Chapter 4, Results and Discussion, this part consists of analysed results and other

calculated comparisons to find sustainable design solutions in the Composite Climate

for the School building type.

Sustainable Development

Sustainable development has been defined in many ways, but the most frequently

quoted definition is from Our Common Future, also known as the Brundtland Report

October 1987:By-World Commission on Environment and Development (Brundtland

Commission, UNO 1984)

"Sustainable development is development that meets the needs of the present without

compromising the ability of future generations to meet their own needs.

It contains within it two key concepts:

the concept of needs, in particular the essential needs of the world's poor, to which

overriding priority should be given; and

the idea of limitations imposed by the state of technology and social organization on

the environment's ability to meet present and future needs."

So, in the field of technology in building design and construction,

"Sustainable Architecture is Architecture that meets the needs of the present without

compromising the ability of future generations to meet their own needs. “
