Passive Solar Energy Buildings
Passive Solar Energy Buildings design is the first step toward achieving climate responsive and sustainable building design. With the introduction of modern construction technologies in the country, the building sector has adopted uniform design and building techniques which is neglecting local climate. In this research climatic data of Lalitpur, Pokhara and Dharan cities has been collected and analyzed with the help of Bioclimatic chart and Mahoney table. A bioclimatic approach has been adopted using the psychometric chart in order to identify passive design strategies.
Whereas Mahoney table has been used to identify design guidelines from humidity and temperature data. From Mahoney table general design guidelines for each city has been found. This research is focused on reduction of energy use in a building with appropriate design strategies like site planning, building orientation, opening size, construction technique and building materials.
This brief discussion has been intended to introduce you to basic types of passive systems that may be used to heat buildings and thereby conserve energy, the roles of climate and solar availability in determining the feasibility of passive solar systems, and some guidelines that may be useful in undertaking feasibility studies and preliminary designs. This will give you a foundation for learning about and utilizing more technically rigorous methods that are available in the engineering literature.
