Low Energy Building

From Swikipedia

Introduction

A Low Energy Building is a very good insulated and passive solar building, with a very low remaining heating and cooling demand. Low energy buildings are designed to provide a significantly higher standard of energy efficiency than the minimum required by national building regulations. They are very often designed without traditional heating systems and without active cooling. They result in a saving of energy consumption of 70 to 90% compared to the existing building stock.

Brief Description

Properly designed LEB (Low Energy Buildings) sometimes called "green buildings" have minimal energy usage, systems operate more efficiently, and they also turn out to be a cheaper option.

A common barrier for LEB's is the perception that the construction cost will be significantly higher, yet studies show that green buildings cost no more than traditional building methodologies.

Benefits of low energy buildings:

• Low energy bill

• Great indoor climate

• Less noise pollution

Low energy technology:

Low-energy buildings typically use high levels of insulation, energy efficient windows, low levels of air infiltration and heat recovery ventilation to lower heating and cooling energy. They may also use passive solar building design techniques or active solar technologies. These homes may use hot water heat recycling technologies to recover heat from showers and dishwashers. Lighting and miscellaneous energy use is allieviated with fluorescent lighting and efficient appliances.
