【摘要】：隨著社會經(jīng)濟(jì)的飛速發(fā)展,工業(yè)化、城鎮(zhèn)化和人民生活水平的提高,對居住環(huán)境的舒適性要求的提高,建筑的用能種類進(jìn)一步增多,建筑消耗的常規(guī)能源有增無減,常規(guī)能源的資源已經(jīng)面臨枯竭,嚴(yán)重威脅到了國家能源安全和經(jīng)濟(jì)可持續(xù)發(fā)展。而新的非常規(guī)能源的開發(fā)在短期內(nèi)因為各種原因很難緩解當(dāng)前的能源問題。進(jìn)一步提高建筑的節(jié)能成了緩解當(dāng)前能源問題的有效途徑。我國自20世紀(jì)80年代初開始,采取分階段提高建筑節(jié)能,以后下一階段在上一階段基礎(chǔ)上節(jié)能30%。1986年~1995年是我國建筑節(jié)能的第一階段,我國制定了第一部建筑節(jié)能設(shè)計標(biāo)準(zhǔn)《民用建筑熱工設(shè)計規(guī)程》JGJ24-86,其基本目標(biāo)是將采暖能耗從當(dāng)?shù)?980到1981年住宅通用設(shè)計的基礎(chǔ)上節(jié)能30%。至今,全國建筑節(jié)能已基本達(dá)到了第三階段,即節(jié)能65%的要求,部分城市已率先實施第四階段75%的節(jié)能目標(biāo)。西安,作為我國古都之首,七大區(qū)域中心城市之一。2007年實施節(jié)能65%的標(biāo)準(zhǔn)距今已有八年,在這八年里,保溫材料、設(shè)計水平及城市經(jīng)濟(jì)都有顯著的提高。本文正是基于國家節(jié)能大趨勢和西安地區(qū)的經(jīng)濟(jì)技術(shù)現(xiàn)狀,試圖探討西安地區(qū)高層住宅從節(jié)能65%提高到75%技術(shù)方面的可行性。本文以代表性的高層住宅建筑,在滿足建筑規(guī)范條列的情況下,通過改變代表性的高層住宅建筑的層數(shù)、層高、窗墻面積比等參數(shù),研究了它們與建筑采暖能耗的關(guān)系,對建筑節(jié)能優(yōu)化設(shè)計提出了一些建議。根據(jù)西安地區(qū)高層住宅建筑節(jié)能75%的建筑物采暖耗熱量指標(biāo),反推各圍護(hù)結(jié)構(gòu)傳熱系數(shù)限值,并進(jìn)行了節(jié)能75%校驗。然后根據(jù)限值,以西安地區(qū)現(xiàn)有節(jié)能構(gòu)造做法為基礎(chǔ),對西安地區(qū)高層住宅節(jié)能75%的圍護(hù)結(jié)構(gòu)構(gòu)造做法提出可行的技術(shù)體系。最后根據(jù)新的技術(shù)體系,評估了西安地區(qū)高層住宅節(jié)能75%經(jīng)濟(jì)效益。通過對西安地區(qū)高層住宅節(jié)能75%的研究,得出西安地區(qū)建筑節(jié)能設(shè)計標(biāo)準(zhǔn)中的相關(guān)參數(shù)及可行性技術(shù)。
[Abstract]:With the rapid development of social economy, industrialization, urbanization and the improvement of people's living standard, the demand for comfort of living environment has been improved, the kinds of energy used in buildings have increased further, and the conventional energy consumption of buildings has increased unabated. The resources of conventional energy have been exhausted, which has seriously threatened the national energy security and sustainable economic development. The development of new unconventional energy is difficult to alleviate the current energy problem for various reasons in the short term. Further improvement of building energy conservation has become an effective way to alleviate current energy problems. Since the beginning of 1980s, China has taken steps to increase building energy efficiency in stages, and the next stage is the first stage of building energy conservation in China from 30.1986 to 1995 on the basis of the previous stage. The first building energy-saving design standard JGJ24-86has been formulated in China. The basic goal of JGJ24-86 is to save energy on the basis of the general design of residential buildings from 1980 to 1981. So far, the national building energy conservation has basically reached the third stage, that is, energy saving requirements of 65%, some cities have taken the lead in the implementation of the fourth stage of 75% of the goal of energy conservation. Xi'an, as the first of the ancient capitals in China, is one of the seven regional central cities. It has been eight years since the implementation of the energy saving standard of 65% in 2007. During these eight years, the thermal insulation materials, the design level and the urban economy have improved significantly. Based on the general trend of national energy saving and the present situation of economy and technology in Xi'an area, this paper attempts to discuss the feasibility of improving the technology of high-rise residential buildings in Xi'an from energy saving 65% to 75%. In this paper, the relationship between the building heating energy consumption and the building heating energy consumption is studied by changing the parameters of the representative high-rise residential building, such as the number of floors, the height of the floor, the area ratio of window to wall, and so on, under the condition that the representative high-rise residential buildings meet the requirements of building codes. Some suggestions on optimal design of building energy conservation are put forward. According to the heat consumption index of buildings with energy saving 75% in high-rise residential buildings in Xi'an area, the limit value of heat transfer coefficient of each retaining structure is pushed back, and the energy saving 75% check is carried out. Then according to the limit value, based on the existing energy saving construction method in Xi'an area, a feasible technical system is put forward for the 75% energy saving enclosure structure method of Xi'an high-rise residence. Finally, according to the new technical system, the 75% economic benefit of energy saving of high-rise residence in Xi'an area is evaluated. Based on the study of 75% energy saving of high-rise residential buildings in Xi'an area, the relevant parameters and feasibility techniques in the design standard of building energy saving in Xi'an area are obtained.
