Newark Unified School District Building Envelope Standards
September 27, 2013
Newark Unified School District Building Envelope Standards Objective: Newark Unified School District determined that a standard for building envelopes should be applied to capital construction projects using Measure G Bond Project funds and future projects. The following guidelines for building envelope design are intended to provide basic parameters for the District with the goal of maximizing the energy efficiency of buildings while maintaining water resistance, minimal maintenance requirements, and aesthetically compelling designs. Exterior materials should be durable and of relatively low maintenance. Maintenance requirements should be consistent with the District’s available maintenance and operations resources. They shall be suitable for the project’s climatic conditions and for the programmatic requirements of the project. This Building Envelope Standard should be applied to all modernization, renovation and replacement projects.
