Optimization Of Window Size On The Teaching Building Of The Single-sided Lighting In The Cold Regions

Classroom indoor light, the thermal environmental quality directly relate to students’learning efficiency as well as physical and mental health, directly determines the level ofschool energy’s consumption. The optimization research to the teaching building indoor lightand thermal environmentis of great significance to reduce the use of energy consumption ofschool buildings, to build an economical campus, and to protect the health of students.The scale of the window opening in the teaching building directly affects the size of thelighting energy consumption and heating energy consumption. The relationship with two ofthem is negative correlation and positive correlation.In order to solve this problem, this paperstudies a university teaching building of Xi’an as the research object, using thequestionnaireinvestigation and field testing methods, quantitativelyanalyze the light of thecollege classroom indoor thermal environment and energy consumption of the status quo inwinter, which in terms of both subjective and objective. Research and testing has shown thatcurrently teaching building indoor light and the thermal environment is not ideal.Throughorganizingthe research test data, the paper analyzed the variation of the lightning and thermalenvironment.,and provide an empirical basis for the establishment of the single-sidedlighting classroom energy simulation program.For the single-sided lightning teaching building’s indoor light and thermal environmentand energy consumption status quo in the cold regions,this paper established a single-sidedlighting teaching building energy consumption model with ECOTECT software, establisheda reasonable simulation parameters, and by comparing the measured data and simulation data,verified the validity of the model. At the same time, changing the window’s opening sizewith the numerical simulation method, in order to compare how the window’s opening size’schanging can affect lighting energy consumption and heating energy consumption, and usingtotal energy consumption (Kwh) for the evaluation index to give a collaborative optimizationto the scales of single-sided lightning teaching buildings.Simulation results show that whenthe window opening size was2.7square meters, the total energy consumption of classroomsreached a minimum value.So we got the optimal balance of the winter indoor lightenvironment and thermal environmentresults. This result further can be used as therecommendation of the teaching building of single-sided lighting or windows scale todifferent directions and different layers.In this paper, we use measured method and software simulated method to study the optimal balance of scale and the energy consumption of the single-sided lighting teachingbuilding window opening in cold regions.The research result provided the reference of thefeasibility to solve the contradictions of the lighting energy consumption and heating energyconsumption to the architects.
