The globalization of construction methods has resulted in the creation of housing models that do not consider actual climatic necessities, nor the site, culture, landscape or energy situation.
This means that there is an increasingly greater separation between man and city because of the creation of places that are alien to man's soul. The stereotyping of building models has not only resulted in low architectural quality but also in an excessive use of territorial resources that has created the need to look for other ways of using space.
Sustainability must consider the relationships between both the building and its energy performance and architecture and landscape to create a new cultural awareness of an alternative model.
ELEMENTS OF SUSTAINABLE ARCHITECTURE
• Minimalist approach
• Reduction of energy consumption
• Rational use of water resources
• Use of bioecologic materials
• Recycling and reuse
REDUCTION OF ENERGY CONSUMPTION
For proper "energy planning" four factors must be considered:
1. Bioclimatic characteristics (orientation, exposition to sunlight, natural ventilation);
2. Use of renewable energy sources (biomass, geothermal, photovoltaic, solar, small wind turbines);
3. The thermal envelope (lower energy needs to heat and cool living areas);
4. Efficiency of utility systems (lower consumption for equal performance);
While the first two are related to the characteristics of the building (also called "passive" characteristics of the building), the last two regard the utility systems which play a crucial role in creating a sustainable building envelope.
