Parametric optimization of an architectural object’s form as a method to improve its energy efficiency

Parametric optimization of an architectural object’s form is one of the design tasks, which architects and project designers face at the stage of structural concept development and design. Improving the performance qualities of a design solution, while providing its energy efficiency, is the purpose of system research in the sphere of architecture and urban planning. The article gives the comparison of calculated compactness ratios of the external envelope for one-, two- and three-, four-, five-, six-, seven-storey 6-apartment compact-form residential houses, comparable in the floor surface area criterion. The application of BEM software packages on the basis of BIM-modeling of buildings is reasonable to substantiate with the optimal functional (consumer) properties of an architectural object. Systematic methodology allows considering the architectural and design problems in the interdisciplinary way. Computer modeling of architectural objects should solve the optimization tasks on the basis of version design and contain an optimization module, which would allow taking the optimal decision at the specified design constraints (conditions) and normative parameters. Computer modeling of architectural objects with the use of structural optimization methods for the version design is a promising area, which requires the formalization of project procedures and developing automated design system tools for designing buildings of various purposes.
