Energy Efficiency

The importance of energy efficiency as a policy objective is linked to commercial, industrial competitiveness and energy security benefits, as well as increasingly to environmental benefits such as reducing CO2 emissions.

Energy efficiency is a generic term, and there is no one unequivocal quantitative measure of 'energy efficiency'. Instead, one must rely on a series of indicators to quantify changes in energy efficiency. In general, energy efficiency refers to using less energy to produce the same amount of services or useful output.

Renewable Energy

Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun (such as thermal, photochemical, and photoelectric), indirectly from the sun (such as wind, hydropower, and photosynthetic energy stored in biomass), or from other natural movements and mechanisms of the environment (such as geothermal and tidal energy). Renewable energy does not include energy resources derived from fossil fuels, waste products from fossil sources, or waste products from inorganic sources."

Bioclimatic Buildings

A bioclimatic building is completely integrated into the cycles of nature and is able to use them without causing damage. The interaction of the main cycles involving the basic elements of soil, water, energy and air should be carefully considered and integrated into the design of buildings and residential developments.

In passive architecture the means that the architect can use for creating a thermally and visually comfortable indoor environment are: solar radiation, wind, orientation and shape of the building, thermal mass of walls and roof, thermal transmittance and color, opening size and type of glazing.
