Analysis of Energy Performance on Envelope Ratio Exposed to the Outdoor

The shape of a building largely contributes to its energy consumption. The current study utilized metrics ofsurface-to-volumeratio,surface-to-floorratio,area-to-perimeterratio, and volume ratio to evaluate building energy performance. Also, the paper focused on the relation between theair-conditionedroom andnon-air-conditionedroom. This approach affects both the design stages of the floor plan and the main designing factors that decide which spaces would becomeair-conditionedspaces such as those mostly occupied by residents ornon-air-conditionedspace such as staircases and elevators. The heating load and cooling load were calculated using the new equation based on the location ofnon-air-conditionedspaces and envelope ratio facing the outdoor. Both thewidth-depthratio and envelope ratio were analyzed using the IES_V.E (Integrated Environmental Solutions Virtue Environment) program. It turns out that, as thenon-air-conditionedspaces increase, both heating load and cooling load were reduced.
