Table 1 Summary of research background
No | Researcher(s) | Location | Year | Independent variable | Conclusion |
|---|---|---|---|---|---|
1 | Akbari and Rashid Kalvir | Iran | 2018 | Geometric form | The most suitable building form in the studied cities is a rectangular form with an east–west direction |
(Tabriz, Yazd, Bandar Abbas) | |||||
2 | Zarghami et al. | Iran | 2016 | Plan form | The L-shaped plan shows the highest energy efficiency |
(Semnan) | (Rectangular and non-rectangular) | ||||
3 | Soheili Fard et al. | Iran | 2014 | Direction, form, symmetry | Iranian architecture manages the amount of energy entering the building in proportion to the function of different spaces throughout the year |
(Kashan) | |||||
4 | Kazanasmaz et al. | Turkey | 2014 | Building form | Form-related factors that directly affect energy consumption are the surface-to-volume ratio and the orientation of the building |
(Izmir) | |||||
5 | Shafiee et al. | Iran | 2014 | Tall building form | The appropriate form of a tall building in terms of receiving solar radiation is the form that has the highest amount of radiation received in winter and the lowest in summer |
(Tehran) | |||||
6 | Granadeiro et al. | Portugal | 2013 | Physical characteristics of the building | Materials, windows area, and building form are the most important factors affecting its consumption |
7 | Kantersa and Horvat | Sweden | 2012 | Geometric form of the building | The form of the building can double the potential for solar energy absorption |
8 | Rafiyan et al. | Iran | 2011 | Form, density, orientation, height of the building | By changing the form, density, orientation, and height of residential buildings, the energy consumption of the building can be reduced by about 45% |
