Passive solar 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. After finding appropriate passive solar building design strategies, model design of two and half storey residential building has been proposed for each city. This research also provides checklists for building design. This will support the concerned municipality to sanction the design drawing as per energy conscious and climatic responsive building design.
