Saving energy has become one of the most important issues. The world seeks different ways to pursue the concept of sustainable development and to solve the crisis of energy shortages. This work is based on the idea of improving energy efficiency in building sector, one of the most significant energy consumers. In recent years, the construction of passive houses has increased. With right criteria and correct design rules, the passive house model is an example of the appropriate use of particular forms of energy and prevailing environmental awareness of resource constraints. The goal of passive houses has traditionally been energy efficiency. The purpose of this paper is to demonstrate how best combinations of low energy consumption and good indoor climate are achieved in a passive home. It is necessary to adhere to the concept of construction such as airtight structures, proper orientation, good insulation, etc. The indoor climate depends on environmental factors that affect personal comfort in a living space. High-quality shading is conducive to more comfortable living and control of the sunlight.
