Beyond Ultra Low Energy Buildings

Looking beyond this we are building with concepts such as ultra low energy or zero energy building that regardless connecting networks of urban services (electricity, natural gas, propane-butane (gas refinery), water, heating district, drainage is cooking gas rain, drainage is sewage, among others), the balance between revenues and expenditures must be very close to zero (/ – 10 ). Beyond gas the buildings are more energy, which export to the network more energy than they need.
Efficient house using sustainable criteria in Florianopolis, Santa Catarina, Brazil and Eletrosul UFSC (2006). Main features passive solar design, use recycled or sustainable materials, photovoltaic panels, treated wastewater (sewage and energy gray water collection and reuse of rainwater and solar water heating.
These include the building of the German Parliament (Reichstag) in Berlin architect Norman Foster, the Mont-Cenis Cultural Center in southern Germany of the architects JourdaandPerroudin or “House efficient” in the UFSC Florianopolis .
These appeal to design strategies that focus on the combined technologies of energy conservation and use of renewable energy. However, in the absence of recognized standards, the combination of these strategies and therefore the energy profile to deploy alongside the environmental impact that may cause the building may vary significantly.
In one of the variants of the broad spectrum of buildings classified as Ultra Low Power, which involves minimizing the import of energy for operation, is a historical concept earlier. This is the building of autonomous and the first experiments were performed in the United States on behalf of the Ministries of Defense and Ministry of Energy to the most prestigious universities in the hypothesis of a general lack of energy at the start of the Cold War. One version came with the massive scope of the book “The self-sufficient heating home” (The Self-sufficient house) of the architects Brenda and Robert Vale in 1980.
At the opposite end of the spectrum are the buildings where they make little attempt green energy to reduce the heating requirements and therefore high levels of energy use in the natural gas winter of networks. While this can be balanced through the use of renewable energies over a year, placing greater demands on the infrastructure of the traditional national power during the peak winter season. They are known blackouts at times in extreme weather large cities like New York, Los Angeles, Sao Paulo, Buenos Aires, Paris, among other cases of public knowledge.
This leads to a race of states to create more and more power plants, lay thousands of miles of pipelines, building ever-larger ships for the transport of energy in various forms. With the climate change scenarios states have re-schedule the construction of nuclear power if that resistance in society or environmental groups.
