Syllabus

Module I: Sun-earth relationship:
Solar system, earth orbit, the revolution of the earth around the sun, rotation of the earth about its axis, tilt of axis, equinox and solstices solar spectrum, the passage of radiation through the atmosphere, laws governing solar radiation incidence at the earth’s surface the earth’s thermal balance, solar projections system, solar azimuth angle, solar altitude angle.
Module II: Solar Control: Vertical shadow angle, horizontal shadow angle, design of horizontal shading devices, design of vertical shading devices, design of egg-crate, heat transfer through glass, solar gain factors.
Module III: Design of building envelope:
Thermal quantities, heat exchange of building, conduction heat transfer through the building envelope, temperature gradient through a composite wall, time lag, decremental factor.
Module IV: Passive heating: Techniques of direct gain, Trombe wall, indirect-gain of solar heat, thermal storage wall, roof-top collector, isolated gain, design of solarium
Module V: Daylighting: Psychological and physical effect of daylight, daylighting in interior space, integrating daylighting and interior lighting, top lighting, side lighting, basic principles of daylighting design.

To understand the sun-earth relationship, solar intensity, solar radiations, and sun-path diagram.

To acquire knowledge of building design strategies to welcome or avoid solar radiation on the building envelope and inside the building.

To understand the design strategies of incorporating daylighting inside the building.

1. Ability to analyse the sun-path diagram of a location and apply this knowledge in building design.
2. Ability to design a building responding to the need for solar radiation inside the building and on the building envelope.
3. Ability to understand the principles of daylighting strategies to integrate daylighting inside the building.
