This document summarizes solar passive architecture techniques for designing energy efficient buildings. It discusses the aims of minimizing energy use and promoting renewable resources. The methodology involves researching passive features and case studies. Passive design uses natural heating and cooling through elements like south-facing glass, thermal mass, and cross ventilation. Historically, the Greeks and Romans designed cities and homes to maximize winter sun exposure. Case studies from India demonstrate current applications of passive solar techniques.

4. INTRODUCTIONPassive design is design that does not require mechanical heating or cooling. Buildings that are passively designed take advantage of natural energy flows to maintain thermal comfort.When sunlight strikes a building, the building materials can reflect, transmit, or absorb the solar radiation. Additionally, the heat produced by the sun causes air movement that can be predictable in designed spaces. These basic responses to solar heat lead to design elements, material choices and placements that can provide heating and cooling effects in a building.

5. HISTORY: 5TH CENTURYThe ancient Greeks planned whole cities in Greece, to allow every homeowner access to sunlight during winter to warm their homes. By running the streets in a checkerboard pattern running east west and north-south pattern every home could face south, permitting the winter sun to flow into the house throughout the day.The Romans used it as their south-facing rooms. They became much hotter in winter than similarly oriented Greek homes because the Romans covered their window spaces with mica or glass while the Greeks did not.

6. Passive heatingTwo primary elements of passive solar heating are -South facing glassThermal mass to absorb, store, and distribute heat There are three approaches to passive systemsdirect gain, indirect gain (trombe wall), and isolated gain.
