How to Use Solar Energy for the House (Area)

Solar energy is available free of charge to every building. Unfortunately, in many climatic areas, solar radiation is very low, so other forms of energy must be used for room heating, hot water, lighting and for the operation of electrical appliances.

Fortunately for those who live in areas full of solar radiation, they can utilize solar energy to meet the energy needs of their houses. But many people also do not know how to use solar energy for the house.
Considerations of energy conscious construction

There are three fundamental points which lead to a considerable reduction in the energy requirement of a domestic building:

  1. Reduction of heat losses
  2. Increase in energy saving through the use of solar radiation
  3. Conscious efforts by users to improve the energy balance

 

The choice of building location itself can reduce the heat losses from a building. Within a small area in a region, conditions will vary; e.g. wind and temperature conditions vary with the altitude of a building site.

Relatively favourable microclimatic conditions result on south-facing slopes when the area of ground is situated on the upper third of the slope but away from the crest of the hill.

When trying to understand how to use solar energy for the house, remember that the shape of the building plays an important role in terms of energy conscious construction. The outer surface of the building is in direct contact with the external climate and gives up valuable energy to the outside air. The design of the building should ensure that the smallest possible external surface is presented to the outside air in relation to the volume of the building. The shape to be aimed for is a cube, although a hemisphere in the ideal case. However, this ideal assumption applies only to a detached house.

This “How to Use Solar Energy for the House” is taken from the book Architects’ Data written by Ernst and Peter Neufert, whereas this book has become the guideline for architecture college students in the world.
