“…However, as the only elements that do not change exhaustively during the life cycle of a building, building geometry factors could also have a potential impact on its lifetime performance. Most research has addressed the effects of building form on energy consumption for dwellings and office buildings [5][6][7][8], while The main goal of this study was to evaluate the role of geometry parameters on the thermal performance of school buildings by performing energy simulations for various design combinations. Moreover, a questionnaire was conducted to investigate the students' subjective preferences for building geometry parameters.…”

This paper discusses the role of geometry parameters including building shape, window to wall ratio, room depth, and orientation on the energy use and thermal comfort of school buildings in cold climates of China. The annual total energy demand and summer thermal discomfort time were compared through computer simulations with DesignBuilder. Furthermore, a questionnaire was conducted that related to the students' subjective preference for various building geometry parameters. Results showed that a maximum of 13.6% of energy savings and 3.8% of thermal comfort improvement when compared to the reference case could be achieved through variations in geometry parameters. The H shape performed the best when the building thermal performance and students' preferences were considered, as well as the various design options for architects. Window to wall ratio, room depth, and orientation should also be carefully addressed in terms of different building types. The results of this study can serve as a reference for architects and school managers in the early design stages of schools in cold climates of China.

e shape of a building largely contributes to its energy consumption. e current study utilized metrics of surface-to-volume ratio, surface-to-floor ratio, area-to-perimeter ratio, and volume ratio to evaluate building energy performance. Also, the paper focused on the relation between the air-conditioned room and non-air-conditioned room. is approach affects both the design stages of the floor plan and the main designing factors that decide which spaces would become air-conditioned spaces such as those mostly occupied by residents or non-air-conditioned space such as staircases and elevators. e heating load and cooling load were calculated using the new equation based on the location of non-air-conditioned spaces and envelope ratio facing the outdoor. Both the width-depth ratio and envelope ratio were analyzed using the IES_V.E (Integrated Environmental Solutions Virtue Environment) program. It turns out that, as the non-air-conditioned spaces increase, both heating load and cooling load were reduced.

“…In addition, the lighting distribution needs to keep a balance between the south-facing window and all but south facing window. The illumination and energy efficiency of window are different depending on the U-value, window mullion detail, transmittance and the SHGC (solar heat gain coefficient) [5]. Therefore, all the windows on each side are designed to the optimal condition considering natural environment.…”

Abstract:The objective of this paper is to design units with well-lighted environment and low-energy consumption in the apartment building. Their daylight and energy performance can be determined by the building shape and orientation. The paper initially produced the results of illuminations and energy efficiency using the daylight and thermal simulations by Autodesk "ECOTECT". It then provided the comparison on simulation results of two type buildings: Flat-type and L-type apartment. The available options for the design incorporating the environmental performance have less flexibility in flat-type apartments than in L-type ones. The best unit in the flat apartment is fixed from -45 to 45 degrees rotation, however, that in the L-type one can change depending on rotating the building. Moreover, if the upper level units had the appropriate environment, the lower level could have larger window areas in order to meet those daylight performance needs. Results show that the facade design should have the different window areas depending on the location of each unit. It can assist in the comfort and low-energy consumption design by using simulation tools that achieve the more predictable understandings.
