Building Sector and Energy Consumption - Essay Example From this essay it is clear tha the ‘average’ building implements materials with relatively low embodied energy and a limited amount of HVAC equipment. The energy ‘efficient’ building achieves an 80% reduction in heating energy demand and 40% reduction in cooling energy demand. The LCA shows how, even with a very significant reduction in operating energy consumption, the energy ‘efficient’ building may consume more energy than the ‘average’ one in relatively short life times if no care is taken about its embodied energy.This paper stresses that the effect of transportation energy requirement becomes also evident in this case, being the highest energy contribution for the ‘average’ building, and the second one, after the embodied energy, for the energy ‘efficient’ building. From a building energy point of view, these distributed urbanization schemes offer more chances for energy efficiency measures and appli cation of renewable energy technologies than centralized urbanization schemes. It is just through transportation energy requirements that sustainable building considerations interact with the higher structure sustainable urbanization approach.  Building energy assessment, extended to its design, construction, and useful life, allows for a proper quantification of the building's energy implications, and hence provides the basis for appropriate planning in the sector.  Energy regulation has a perceptive character, and its objective should be to establish and limit the upper bound for the buildings energy consumption.... ows how, even with a long analysis period (100 years), the energy 'efficient' building may consume more energy than the 'average' one if care is not taken about its EE. Evolution of accumulated energy consumption for two 150 m2 dwellings, an average one and another with pretensions of energy efficiency on basis of its reduced operating energy demand. (Laustsen, 2003) The results presented in Fig. 1 assumed a rather low increase in operational energy efficiency, but even with higher energy efficiency improvements we may find similar results with lower life cycle periods. The 'average' building implements materials with relatively low embodied energy and a limited amount of HVAC equipment. The energy 'efficient' building achieves an 80% reduction in heating energy demand and 40% reduction in cooling energy demand. The LCA shows how, even with a very significant reduction in operating energy consumption, the energy 'efficient' building may consume more energy than the 'average' one in relatively short life times if no care is taken about its embodied energy. Life cycle analysis for two 150 m2 dwellings, an average one and another with pretensions of energy efficiency on basis of its reduced operating energy demand, for a life time of 30 years. (Addis, 2002) The effect of transportation energy requirement becomes also evident in this case, being the highest energy contribution for the 'average' building, and the second one, after the embodied energy, for the energy 'efficient' building. From a building energy point of view, these distributed urbanization schemes offer more chances for energy efficiency measures and application of renewable energy technologies than centralized urbanization schemes. It is just through transportation energy requirements that sustainable
