The transition to secure, sustainable, low-energy systems will have a significant effect on the way in which we design and construct new buildings. In turn, the new buildings that are constructed will play a critical role in delivering the better performance that would be expected from such a transition. Buildings account for about half of UK carbon dioxide (CO2) production. So it is urgent to ensure that energy is used efficiently in existing buildings and that new building stock is better able to cope with whatever the future holds. 相似文献

The paper analyses trends in energy use and carbon dioxide emissions in the Swedish building sector between 1970 and 2000 with focus on the development of energy efficiency in the average stock of buildings and in the new construction. The energy efficiency improved throughout the seventies and early eighties, and studies revealed major potentials for further improvements. However, the energy efficiency has levelled off with almost no improvement during the nineties. The statistics for new-constructed multi-dwelling buildings indicate increasing energy use per floor area since 1995, and even more amazing: the new-constructed multi-dwelling buildings are at the same level of energy efficiency as the average existing building. Parallel to this development, the best available technology represented by low-energy buildings, uses less than a third of the energy used in average new buildings. Much of this development may be explained by changes in energy prices. The increasing oil price between 1972 and 1985 correlates well with the improvements in energy efficiency, even though the effect was limited by the low electricity price following the nuclear power programme. However, promotion of energy efficiency is complicated by the ineffective distribution of costs and benefits between actors, especially in the new construction. Moreover, to the residents energy cost is a small part of the expenditures and energy efficiency is merely one of many qualities valued in a building. An important factor behind the increasing energy use in new-constructed multi-dwelling buildings may also be new exceptions in the energy standards which were introduced to promote district heating. Finally, the paper gives some policy recommendations to improve the energy efficiency in the Swedish building sector: Not to support supply substitution at the expense of energy efficiency; Regulations for individual measurements and debiting of space and water heating; Strengthening of the energy standards to promote technical efficiency in the new construction. 相似文献

Sustainable buildings have an important role in achieving sustainable development by improving energy utilization and environmental performance. Buildings are considered as the biggest single contributor to world energy consumption and greenhouse gas emissions. In Saudi Arabia, the significance of the building sector can be described on the basis of per capita electricity consumption, per capita carbon dioxide emissions, and the increasing number of buildings because of economic and population growth. Therefore, the country should consider establishing energy-efficient buildings to promote sustainable development. Efforts in developing energy-efficient technologies should increase for the national energy policy. This article comprehensively describes the current challenges and opportunities of energy consumption and various energy conservation options that are viable for the Saudi building sector. Current policy efforts for improving energy efficiency in Saudi buildings have been analyzed to enhance the sustainable development in the country. The study reveals that the energy conservation policy of the country has fairly improved in the past decades. However, the country has to focus on this area and perform urgent measures to adopt energy-efficient technologies in the building sector. 相似文献

Electric lighting is one of the major energy consuming items in many non-domestic buildings. Using appropriate energy-efficient light fittings with dimming controls and proper daylighting schemes can help reduce the electrical demand and contribute to visual comfort and green building development. This paper presents a study on the energy and lighting performances for energy-efficient fluorescent lamps associated with electronic ballasts and high frequency photoelectric dimming controls installed in a school building. Electricity expenditures and indoor illuminance levels for a workshop and a classroom employing high frequency dimming controls were analyzed. Simple prediction methods were used to illustrate the lighting savings. The findings provide the operational and performance information, which would be applicable to other spaces with similar building layouts and lighting schemes. 相似文献
