Houses that use solar radiation for heating purposes are also energy-saving buildings, therefore, the analysis of the impact of passive systems carried out in this chapter will also be related to energy-saving construction methods and their impact on the architecture.

The demand of a single-family house for thermal energy generally depends on the specificity:
- places, in which it is located,
- the building,
- using.

Single-family construction using solar energy for heating purposes, can be designed both in the form of distributed buildings, and compact (serial, atrialnej, or terrace). For this type of houses it is important to be able to orientate their longer side towards the south and allow the sun's rays to reach the southern elevation within a minimum 6 hours a day. The low angular height of the Sun above the terrain, especially in winter, in spring and autumn (from 15 do 40°) limits the distance of placing anything in front of the southern elevation. Also the azimuths of the sun in hours 8:30 i 15:30 marked by lines drawn at an angle of 45 ° to the north-south axis, measured from the extreme points of the southern elevation. Thus, these conditions dictate that all possible obstacles be moved far away, which will shade the southern elevation.

The amount of shading at noon at different times of the year by an obstacle with a height "h" and the determination of the non-shaded area.

Local climate - microclimate, it is not just a function of the geographic climate, but also local conditions: topographic shape, wind rose, conditions of insolation, type of surface, vegetation, water, management, etc..
It is also of great importance for the health of the home's inhabitants, what happens under the top layer of earth (underground water decks, deposits, etc.).
In order to create the best microclimatic conditions for the facility, the location of which is possible to choose only in exceptional cases, all microclimatic factors in a given area should be analyzed and shaped in an optimal way.

If the location area is undulating, hilly, then convective air movements occur, and all depressions and steam are the most unfavorable locations, because cold is gathered in them, humid and often polluted air.

Convective air movements in hilly terrain and their influence on the heat demand of buildings.

External barriers protecting the building against excessive winds: a) a clump of green in the form of a triangle, b) "small architecture”, c) landform, d) backfilling the facade and roof of the house, e i f) the effect of the green barrier on the temperature in the spaces between the blocks
