Winter Temperature
In December the temperature drops down to 17.6 °C.
I planned a solar house with a special roof, where the sunbeams can only enter the house in the winter. Thereby the internal temperature is always between 18 °C and 25 °C; only with the energy of the sun and without any heating system.
In December the temperature drops down to 17.6 °C.
In August the house reaches its maximum temperature of 24.7 °C
The cost of this solar house will approximately be 1.2 Million US Dollars.
To calculate the length and the angle of this big roof, complex mathematical calculations were neeeded.
