visual comfort

Various researches have introduced methods to use daylight in office buildings in the Middle Eas t zone, but none of them have ever considered the use of plant leaf arrangement, called phyllotaxis, as a comprehensive solution for harves ting daylight. The idea of the Phyllotaxis Tower has been raised for several years but the main ques tion of this research is whether using the phyllotaxis model is capable of exploiting daylight in high-rise buildings or not. So, in response to this ques tion, the main aim of the research was set to evaluate daylight efficiency in high-rise office buildings by presenting an exemplary and phyllotaxis-inspired design. The research method is encompassed several s teps including, s tudying the literature on the subject firs tly, then modeling a prototype building based on the Biomimicry Problem-Based approach, and eventually computer simulation to evaluate the performance of the proposed building. The results show that office units can get daylight illuminance of 500 lux at 50% of operating time per year in addition to proper performance on four single days of different seasons of the year. Furthermore, the sample building obtained label B of energy consumption from S tandard No. 14254 presented by the Ins titute of S tandards and Indus trial Research of Iran, which has been compared with the energy label of 45 office buildings in the same location and same climate conditions, based on the figures are defined on the aforementioned s tandard and has the bes t performance among them.

Purpose : The study aims to study the effect of architectural design parameters on IEQ in accomplishing school smartification. Method : The research was conducted in school buildings located in Tabriz, Iran. The indicators chosen to represent IEQ are the adaptive PMV model used for thermal comfort, imageless daylight glare probability used for visual comfort, and CO2 concentration used for IAQ assessment. The simulation technique was used to collect data for a generative parametric school model. The method of data analysis includes a multivariate linear regression algorithm, t-test statistic, and one-way analysis of variance. The studied variables are dimensions of classrooms with the fixed area, Percentage of window area on a wall, window height, Shading, and protrusions in plan design. The stepwise method for multivariate linear regression in SPSS was used to assess the vital IEQ indicator in terms of thermal and visual comfort and CO2 concentration. Findings : The study found that among studied indicators, the south facade window ratio significantly correlates with IEQ. The other CRI parameters are the north window ratio and north window height. the findings revealed that to increase the IEQ in schools, facade design is more critical than the plan. The higher the window surface on the south, north, west, and east faces, the greater the thermal comfort and glare probability is. Conclusion : However, increasing the height of the windows can reduce glare and also increase thermal comfort. Thermal comfort improves as the length of the southern classrooms rises. On the bright side, it has no noticeable glare effect.
