为了能够在住宅建筑的设计阶段了解阳台设计方案对于室内物理环境的影响,利用ECOTECT软件对住宅建筑内部空间进行了照度和热环境模拟,对比分析了不同阳台设计方案下,室内采光系数、室内24 h逐时温度变化和室内24 h逐时得失热量变化。结果表明,利用ECOTECT软件可以直观地模拟多种阳台形式对于室内光热环境的影响,能够为阳台方案的选择提供参考。 相似文献

This work takes benefit from two advanced building technologies through the integration of an anidolic daylighting system and an electro-chromic glazing in a building facade for achieving an optimal control of the daylight flux entering in an office room. Computer simulations of different systems configurations, based on ray-tracing techniques, were used to identify the optimal anidolic system design. Once installed in an experimental building the visual and thermal performance of the anidolic system coupled to an electrochromic glazing was assessed by way of on-site monitoring. These performances were compared to those offered by a conventional double glazing unit installed in an identical neighbouring room. An evaluation of users comfort was achieved by way of a survey involving 30 different subjects. Their visual performance during specific tasks performed on a VDT screen and/or on a sheet of paper was used to compare the lighting conditions. The main results of this detailed experimental study, showing the capability of such a combined daylighting system to control the daylight flux entering a working space, are presented in this paper. 相似文献

This paper presents a novel method for designing of an occupant-centric shading algorithm that utilizes visual comfort metric as the form-generating criteria. Based on the premise of previous studies that demonstrate glare as the most important factor for operating shading devices, GlareShade is introduced as a simulation-based shading methodology driven by occupant's visual comfort. GlareShade not only responds to changing outdoor conditions such as the movement of the sun and the variation of cloud cover, but it also accounts for building specific local conditions. GlareShade draws its strength and flexibility from an occupant-centric approach that is based on the visual field of view of each occupant as the occupant is performing common visual tasks in a given environment, and the developed shading system is linked to a distributed sensing network of multiple occupants. ShadeFan is demonstrated as a proof-of-concept dynamic shading system utilizing the GlareShade method. 相似文献

Building performance simulations and models of human visual comfort allow us to predict daylight-caused glare using digital building models and climate data. Unfortunately, the simulation tools currently available cannot produce results fast enough for interactive use during design ideation. We developed software with the ability to predict visual discomfort in real time. However, we know little about how users react to simulation feedback presented in real time. In our study, 40 subjects with backgrounds in building design and technology completed two shading design exercises to balance glare reduction and annual daylight availability in two open office arrangements using two simulation tools with differing system response times. Subjects with access to real-time simulation feedback tested more design options, reported higher confidence in design performance and increased satisfaction with the design task, and produced better-performing final designs with respect to spatial daylight autonomy and enhanced simplified daylight glare probability. 相似文献

良好的天然采光不仅为学校创造出一个优美愉快的学习环境,还有益于学生们的身心健康。然而,我国对学校天然光的现状研究还处在起步阶段。笔者回顾了我国学校天然采光研究现状和现行采光设计标准,并以南京市2所中学中的12间教室为研究对象,对其天然光环境进行实地测量,并根据我国最新修订和颁布的《建筑采光设计标准》GB50033--2013进行评估分析。结果显示,尽管这些教室在设计上基本满足我国最新的采光照明设计标准,但教室内普遍存在着水平面照度不均匀、直射阳光等问题;其次是黑板的采光照明,几乎所有被测教室都存在着反射眩光的问题。 相似文献

我国在学校天然采光方面的研究起步较晚,相关标准的制定也主要是借鉴西方的研究成果,因此有必要根据我国地域、气候、人文、经济等情况进一步修正。本次初步研究尝试从量化研究和质化研究两个方面入手了解中国学校天然采光。在文献回顾基础上,本文主要介绍研究小组对2所南京市中学的300个学生的问卷调查结果。希望本次研究可以初步了解南京市中小学教室的天然光环境现状,并为我国学校天然采光研究,以及采光设计标准的重新修订起到一定的抛砖引玉作用。 相似文献
