为了解绿色建筑运行后实际能耗和室内环境品质,选取位于不同气候区不同城市共31个获得绿色建筑认证的办公建筑,通过现场调研和部分典型项目室内环境参数的长期测试,结合用户主观问卷调研,比较了不同气候区不同绿色办公建筑运行能耗和室内环境品质的情况,并与相同气候区普通办公建筑的能耗和室内环境品质进行了对比。结果表明,我国不同气候区绿色办公建筑的能耗总体低于当地平均水平,并接近《建筑能耗定额标准》中能耗限制的目标值,但也存在一些获得标识的绿色办公建筑能耗偏高的情况。总体来看,绿色办公建筑的能耗高低和星级的关系尚不清晰。在室内环境品质满意度方面,用户对绿色建筑的满意度明显高于常规建筑,这个差异在室内热环境及空气品质上尤为明显。在此基础上,分析了影响绿色办公建筑运行能耗高低和室内环境品质优劣的原因,为设计和运行阶段进一步提升我国绿色建筑性能提供参考。 相似文献

对夏热地区绿色公共建筑的运行能耗及室内环境品质进行了调研及分析。选取位于夏热冬暖和夏热冬冷地区不同城市共14个获得绿色建筑运行标识的办公建筑,通过调研和典型项目室内环境现场测试,分析了绿色办公建筑运行能耗和室内环境品质的情况。研究表明,夏热地区绿色公共建筑运行能耗符合标准要求,公共建筑最大月能耗普遍出现在天气最热的月份,商业建筑和办公建筑的最低能耗出现在天气最温和的月份,空调能耗波动性最大,且公共建筑中酒店建筑空调能耗占比最大;办公建筑和酒店建筑的室内环境品质满足标准要求,但商业建筑的室内空气质量有待提高。针对运行效果提出建议,以期为我国夏热地区绿色公共建筑运行效果提升提供参考。 相似文献

《民用建筑能耗标准》是贯彻落实建筑能耗总量控制、规范建筑运行能耗管理的重要举措。《标准》"公共建筑能耗"章节,从一般规定、能耗指标、能耗指标修正方法等三个方面,针对办公建筑、宾馆酒店建筑、商场建筑等三类量大面广的公共建筑及其细分种类,按室内环境营造方式分为A类和B类建筑,分别给出严寒和寒冷地区、夏热冬冷地区、夏热冬暖地区、以及温和地区的各类公共建筑能耗指标的约束值和引导值,以及根据公共建筑实际使用强度确定能耗指标实测值的修正方法。《标准》"公共建筑能耗"章节是在前期住建部等有关部委和各地建筑节能主管部门大量能耗统计、审计得到数据基础上完成的,对于推动公共建筑运行能耗总量控制必将起到重要作用。 相似文献

夏热冬冷地区办公建筑自然采光效果模拟分析 总被引:1,自引:0,他引:1
选取夏热冬冷地区苏州市某办公建筑作为模拟对象,采用Ecotect结合Radiance软件模拟建筑内自然采光情况,计算建筑内各楼层的平均自然采光系数与全自然采光百分比,分析玻璃可见光透射比、窗墙比对建筑自然采光效果和照明能耗节约量的影响。研究表明,采用可见光透射比较高的玻璃,适当增加建筑外窗面积,有助于提高建筑采光系数,改善自然采光环境,节约建筑照明能耗。 相似文献

The accurate prediction of the visual comfort zone in an indoor environment is difficult as it depends on many parameters. This is especially the case for large compact urban areas in which the density and shadow from neighboring buildings can limit the accessible daylighting in indoor spaces. This paper investigates the satisfaction range for illuminance regarding indoor air temperature in office buildings and the significant parameters affecting this range in six office buildings in Tehran, Iran. Lighting comfort has been evaluated by a subjective survey (509 total responses) and field measurement. The questionnaires were filled out in 146 and 109 rooms in summer and winter, respectively. The results show that the illuminance should not be less than 550 lx, while illuminance between 600 and 650 lx provides the highest satisfaction level. The satisfaction with lighting level is affected by individual parameters such as age, type of activity, and environmental parameters such as window orientation, external obscurations, and season. A relationship was observed between lighting level satisfaction and thermal condition acceptance, and the overall comfort depends more on thermal conditions than the lighting level. 相似文献

Indoor environmental quality (IEQ) has become an important component of green building certification schemes. While green buildings are expected to provide enhanced IEQ, higher occupant satisfaction, and less risks of occupant health when compared with non‐green buildings, the literature suggests inconsistent evidence due to diverse research design, small sample size, and weak statistical analysis. This study compared several outcomes pertinent to IEQ performance in green and non‐green office buildings in Singapore. Adopting a cross‐sectional study design, objective measurements were taken in eight green and six non‐green buildings, and satisfaction and acute health symptom risks of 367 occupants were obtained. Green buildings exhibited lower concentration of PM2.5, bacteria, and fungi and maintained temperature and humidity more consistently compared to non‐green counterparts. The mean ratings for satisfaction with temperature, humidity, lighting level, air quality, and indoor environment were higher in green buildings (with statistical significance P < 0.05). There was statistically significant reduction in risk of occupants having headache, unusual fatigue, and irritated skin in green buildings. Although matching of buildings and occupant characteristics, survey participation bias, and sampling duration (a 1‐week snapshot) of IEQ monitoring remain as limitations, this study offered positive association of green buildings with qualitatively and quantitatively measured performance of IEQ. 相似文献
