Low Energy Buildings Design and Human Comfort Solutions

Abdeen Omer

The use of renewable energy sources is a fundamental factor for a possible energy policy in the future. Taking
into account the sustainable character of the majority of renewable energy technologies, they are able to preserve
resources and to provide security, diversity of energy supply and services, virtually without environmental impact.
Sustainability has acquired great importance due to the negative impact of various developments on environment.
The rapid growth during the last decade has been accompanied by active construction, which in some instances
neglected the impact on the environment and human activities. Policies to promote the rational use of electric
energy and to preserve natural non-renewable resources are of paramount importance. Low energy design of urban
environment and buildings in densely populated areas requires consideration of wide range of factors, including
urban setting, transport planning, energy system design and architectural and engineering details. The focus of the
world’s attention on environmental issues in recent years has stimulated response in many countries, which have led
to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building
energy consumption is to design buildings, which are more economical in their use of energy for heating, lighting,
cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than
air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy
in buildings and agricultural greenhouses can, also, significantly contribute towards reducing dependency on fossil
fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will
contribute to preservation of the ecosystem by reducing emissions at local and global levels. This will also contribute
to the amelioration of environmental conditions by replacing conventional fuels with renewable energies that produce
no air pollution or greenhouse gases. This study describes various designs of low energy buildings. It also, outlines
the effect of dense urban building nature on energy consumption, and its contribution to climate change. Measures,
which would help to save energy in buildings, are also presented.
