1. Whrite about environmental classrooms at universitiesThe environmental classrooms at universities talk about of the bioclimatic architecture is ultimately a adapted to the environment, sensitive to the impact that has on nature, environment and trying to minimize energy consumption and with it architecture, environmental pollution.Bioclimatic house but need not be more expensive or cheaper than conventional. No need to purchase and / or installation of mechanical HVAC, but plays with architectural elements always to increase energy efficiency and comfort get naturally. For this, the bioclimatic design is a set of constraints, but there are still degrees of freedom for the design according to individual taste.Bioclimatic architecture takes into account the terrain, the path of the sun, drafts, etc., applying these aspects to the distribution of space, openness and orientation of windows, etc., in order to get energy efficiency.Its objectives are: Achieve indoor environmental quality, it ie appropriate conditions of temperature, humidity, air movement and quality. Consumption affecting the sustainable development of the place: the consumption of water or other commodities above their capacity for renewal. Contribute to economize on fuel consumption (50-70% reduction on normal consumption). Reduce emissions of polluting gases into the atmosphere (50-70%) Reduce water consumption and lighting (between 30% -20% respectively)Its advantages are:A green building is a structure that has been designed in order to increase energy efficiency and reduce environmental impact, while improving the welfare of its members. For example, enhancing the natural light inside a building not only will save money and reduced environmental impact due to lower consumption of electricity (a significant percentage of electricity is made from burning fuels fossils with the consequent release of polluting greenhouse gases, especially CO2), but also may reduce the potential stress of the occupants.Saving money on electricity bills and gas.Sustainable building is not characterized by a particular trait or is limited to a set of standards or requirements. It is a complete process from the choice of the land on which will begin construction until the projection of the structure and the use of ecological materials and the possibility of recycling them.Achieve greater harmony between man and nature. It would house-bunker; that ignores its climatic environment and uses powerful air-conditioning units to solve the problem, to a house that integrates and uses his environment and climate to meet their energy needs.
