The challenge is to design the most sustainable home that uses the full potential of solar energy.

The concept is based on the following scientific principles for the optimal use of solar energy:

 - “… the orientation of the majority of window openings to the south is advisable. The amount of energy obtained by passive use of solar radiation decreases with windows oriented to the east and west, and is completely excluded with windows oriented to the north.. "

- "… the house needs to be divided into temperature zones and the premises should be planned with a similar operating temperature. Auxiliary rooms are moved to the northern part. Bedrooms should be placed in the middle of the house. The main "daytime" rooms occupy the southern part of the house ..."

- "... the largest windows are directed to the south (for the northern hemisphere) bring more heat than they lose ..."

Everything suggests that the most reasonable thing is to open the object to the south side. The idea is to increase the number of southern facades!

The arrangement of exactly five facades is most effective, since it does not lead to a critical turn of the western and eastern facades to the north side.

The southern facade has the maximum glazing area.

Comparison:

That's not all. Let the sunlight first enter the atrium through the glazing on the south side, and then pass and scatter in it and illuminate all adjacent rooms through the internal windows.

As a result:

- an abundance of light in all rooms, with low heat loss

- natural ventilation

- comfortable microclimate

The shape and slope of the roof are based on calculations to achieve the highest efficiency. The southern slope (the largest area) is perpendicular to the sun's rays (summer time); solar panels placed throughout its area. Calculation of the interdependence of the slopes allows you to create the most compact volume for greater thermal efficiency.

In order to control the incoming light and heat in the summer, sun protection is provided for all southern windows (the role of shutters, curtains on the guides). Loggias, playing the role of visors, are also brought out to the south side. Vacuum 3-chamber double-glazed windows filled with argon are used. Glasses are tempered to avoid heat shock, covered with an energy-saving dioxide membrane.

There is a swing under the ceiling of the atrium!

Other green solutions:

- geothermal heating

- solar panels

- solar collectors

- light sensors (drive unit on windows in the daytime and on artificial lighting in the evening)

- collecting rainwater from the entire roof area and using it for flushing in bathrooms

- effective thermal insulation

- use of reflective material IZOFOL in interior decoration of external structures

- several layers of environmentally friendly thermal insulation - internal and external

- natural ventilation

- natural building materials: timber frame and timber cladding

- natural finishing materials (solid wood, plywood treated with bleached oil)
