A technical evaluation index for curtain wall and cladding facades

An assessment framework derived from face-to-face interviews with building managers and comprehensive condition surveys of commercial buildings is proposed. Twenty-eight parameters are identified and tested for significance in affecting the technical evaluation score for curtain wall and cladding facades. The proposed framework is intended as a practical benchmark to assess and document the existing condition of the facade and further assist in the proper management of the maintenance strategy of the facade throughout its whole service life.
