A building is an element that consumes great quantities of primary energy both during construction and operating life. Buildings are reported to consume 40% of total primary energy in Europe. Efficiency and saving policies in this sector should be priority to reduce the European energetic dependence on third countries as well as to diminish greenhouse emissions.
The present work is aimed at review the results obtained during the first operating year of a public building with high energetic qualification in Mérida (Spain), which develops novel techniques on efficiency, energy saving and integration of renewable energies applied to the building sector. The building was constructed according to the climatic characteristics of Mérida. Diverse techniques regarding passive solar collection and thermal isolation, window and roofing shadowing and natural lighting were accounted for.
The results showed that it is possible to air-condition public buildings in extreme weather regions by applying specific measures to minimize energy consumption with the use of renewable energy sources (solar energy and biomass). Based on the actual energetic results, the economic, energetic, and environmental feasibility of this kind of building is also analyzed. 相似文献
Population of the world is growing with increasing rate and it seems that existing fossil fuel energy sources will not be able to meet energy demand in the near future. Energy is not only crucial for civil sector but also it is one of the most important assets in defense sector. Energy for military operations is mostly provided from fossil fuel as it is the case in other sectors; however, fossil fuels have hazardous effects to the environment and cause global environment concerns. These drawbacks of fossil fuels are also valid for battlefield. Furthermore, transportation of fossil fuels causes extra safety and logistics problems in military case. In this study, we developed a hybrid green energy solution with wind, solar, and batteries together to minimize or eliminate the fossil fuel demand for the battlefield. Results of our algorithm are superior to the already used diesel generator solution from the point of view of cost and various other aspects. The novelty of our study stems from applying optimization of hybrid green energy solution to military case with battlefield constraints. 相似文献
