Question

a. How will you use the solar energy for day lighting, space heating and cooling in the buildings? Explain in detail.

  

b. What are building integrated micro wind turbines? explain how you will use them in a beach resort (Hotel, ex- Millenium beach resort) project.

Answer 1

Solution a. Solar energy can substantially improve the design of the building. It offers numerous advantages over conventional energy resources. It is free of cost just after recovering the initial capital costs also the recovery time is usually short. It is available everywhere in this globe and also it is inexhaustible as it is a renewable resource. It is clean and also reduces the need for fossil fuels and hydro generated electricity and its disadvantages over our environment. It can be integrated into the building, which can lower the requirement for energy distribution.

Solar buildings operate according to three principles: collection, storage, and distribution of solar energy. These principles are integrated into two main solar systems: passive and active solar systems. They can be integrated simultaneously into the building design

Passive solar energy refers to systems that absorb, store, and distribute energy from the sun without relying on mechanical devices such as pumps or solar panels, which require additional power. In other words, passive solar energy does not involve any panels or batteries and nothing is supplied to the general electricity grid. Passive systems can be used for heating or cooling.

In the active system, heat is transferred mechanically through the use of air or water. An active solar system uses mechanical equipment to collect, store, and distribute heat from the sun. Active systems consist of solar collectors, a medium to store, and a distribution system. These systems are usually used for heating water, conditioning, electricity production.
