【摘要】：在各項(xiàng)建筑節(jié)能技術(shù)措施中,活動(dòng)遮陽(yáng)對(duì)降低建筑能耗、改善室內(nèi)光熱舒適度具有重要作用。目前國(guó)內(nèi)建筑活動(dòng)遮陽(yáng)控制方式仍以手動(dòng)調(diào)節(jié)為主,由于人體控制遮陽(yáng)調(diào)節(jié)的行為受主客觀各種因素影響具有隨機(jī)不確定性,因此,研究活動(dòng)遮陽(yáng)隨機(jī)調(diào)節(jié)模式對(duì)于客觀準(zhǔn)確分析其節(jié)能效果和室內(nèi)光熱舒適改善具有重要意義。 本文選擇夏熱冬冷地區(qū)寧波的一典型辦公建筑為研究對(duì)象,通過室外溫度、太陽(yáng)輻射和遮陽(yáng)狀態(tài)等實(shí)際測(cè)試及非線性回歸方法,將遮陽(yáng)調(diào)節(jié)狀態(tài)分為遮擋窗戶面積的0%,25%,50%,75%,100%五種進(jìn)行累積比數(shù)Logit分析,確定了太陽(yáng)輻射是遮陽(yáng)調(diào)節(jié)行為的驅(qū)動(dòng)主因。利用馬爾科夫鏈方法,建立了基于實(shí)測(cè)遮陽(yáng)行為調(diào)節(jié)模式的隨機(jī)模型。采用建筑性能整合分析平臺(tái)(BCVTB),構(gòu)建了活動(dòng)遮陽(yáng)隨機(jī)調(diào)節(jié)性能分析模型,并首次實(shí)現(xiàn)了與建筑性能模擬分析軟件Energyplus的耦合計(jì)算。 根據(jù)上述建立的模型,對(duì)典型辦公建筑不同朝向窗戶的節(jié)能和光熱效果進(jìn)行分析。不僅從基礎(chǔ)室溫、太陽(yáng)輻射透過量、能耗等常規(guī)指標(biāo)作了比較,并引入考慮太陽(yáng)輻射對(duì)人體影響的室內(nèi)熱舒適改進(jìn)指標(biāo)PMVrad和PPDrad進(jìn)行更為準(zhǔn)確的分析。結(jié)果表明：活動(dòng)外遮陽(yáng)能獲得最佳的能耗和室內(nèi)熱舒適環(huán)境,活動(dòng)內(nèi)遮陽(yáng)與LOW-E中空玻璃窗相當(dāng),最差的是普通中空玻璃窗。室內(nèi)熱舒適的時(shí)間活動(dòng)外遮陽(yáng)要比LOW-E中空玻璃窗多6%-20.8%,比普通中空玻璃窗多20.5%-49.7%。 根據(jù)不同主客觀光環(huán)境評(píng)價(jià)指標(biāo)的全面綜合分析,活動(dòng)遮陽(yáng)對(duì)改善室內(nèi)光環(huán)境效果也很顯著：室內(nèi)工作面適宜照度的時(shí)間活動(dòng)內(nèi)外遮陽(yáng)要明顯優(yōu)于LOW-E中空玻璃窗(約是2-3倍),且照度波動(dòng)也控制得比較好；在亮度方面,活動(dòng)內(nèi)外遮陽(yáng)能較好地控制工作面與背景環(huán)境的亮度對(duì)比度。結(jié)合Radiance和Evalglare眩光分析軟件,充分考慮人眼對(duì)光環(huán)境的自適應(yīng)調(diào)節(jié),從眩光指標(biāo)DGI和DGP作進(jìn)一步分析,統(tǒng)計(jì)計(jì)算表明活動(dòng)內(nèi)外遮陽(yáng)基本上都優(yōu)于LOW-E中空玻璃窗,并且活動(dòng)外遮陽(yáng)效果更顯著,西向窗戶工作時(shí)間眩光比LOW-E中空玻璃窗低約20%,東向和南向低約4%,并且減少約1／2到2/3的強(qiáng)眩光。
[Abstract]:In the construction of energy-saving technical measures in the activities, shadingtoreduce building energy consumption, improve indoor thermal comfort plays an important role. The current domestic construction activity is still to manually adjust the shading control mainly because of subjective and objective factors to control human behavior regulation effect with random shading uncertainty, therefore, research activity regulation mode for objective random shading the accurate analysis of the effect of energy saving and indoor thermal comfort improvement has important significance.
This paper selects a typical office building in hot summer and cold winter area of Ningbo as the research object, through the actual test of outdoor temperature, solar radiation and shading condition and nonlinear regression method, the state regulation is divided into sun shade windows area 0%, 25%, 50%, 75%, 100%, five cumulative odds Logit analysis, to determine the sun the main reason is the radiation driven sunshade to adjust behavior. Using the method of Markov chain, stochastic model was built based on the mode of regulating behavior of measured shading. The building performance analysis integration platform (BCVTB), established the analysis model of random adjusting performance of movable sunshade, and the first to achieve the building performance simulation calculation and coupling analysis software Energyplus.
According to the established model of a typical office building towards the window energy and thermal effect analysis. Not only from the basis of room temperature, the solar radiation flux, compared to conventional indicators of energy consumption, and considering solar radiation to human body thermal comfort improvement index PMVrad and PPDrad for more accurate analysis. The results showed that the activity of shading can obtain optimum energy consumption and indoor thermal comfort environment, activities in shading and LOW-E hollow glass window, the worst is the common hollow glass window. The indoor thermal comfort time shading than LOW-E hollow glass window 6%-20.8% more than ordinary insulating glass windows 20.5%-49.7%.
According to the comprehensive analysis of the tourism environment evaluation index of different subject activities, to improve the indoor light environment shading effect is also very obvious: indoor working face suitable illumination inside and outside shading was superior to that of the LOW-E hollow glass window of time (about 2-3 times), and the irradiance fluctuations also control better; in brightness, brightness contrast the activities of exterior shading can better control the working face and the background. The combination of Radiance and Evalglare glare analysis software, considering the adaptive regulation of human eye to light environment, further analysis from the glare index of DGI and DGP, statistical calculation showed that the activity of exterior shading basically is better than the LOW-E hollow glass window, and the movable exterior sunshade more obviously, West to the window working time is about 20% lower than the glare of LOW-E hollow glass windows, the East and south by about 4%, and reduce glare about 1 / 2 to 2/3.
