Façade Renovation of the Wexner Center for the Arts
The Wexner Center for the Arts went through a major façade renovation to fix the water leakage and condensation problems. The work included replacing glazed skylights, curtain walls, and roofs. This paper describes how renovation work has been done with modern technologies to study thermal and lighting performance on the new façade. In addition to the computational analysis, a full scale mock-up was constructed in a laboratory for air, water, and structural test, and to evaluate the condensation resistance performance. Currently there are no industry standards for condensation evaluation for a mock-up of this size. The mock-up test method refers to ASTM C 1199, “Standard Test Method for Measuring the Steady-State Thermal Transmittance of Fenestration Systems Using Hot Box Methods,” and AAMA 1053 test procedures but with modifications to suit the project. The new façade of the Wexner Center is a perfect example of how façade design can be done with modern analyses tools and a coordinated design approach to deliver an environmentally efficient cladding system. The paper also describes the issues for the current test standards to the projects that have specific design conditions.
