Reading Health System recently completed a 465,000 SF building with 88,000 SF of Green Roof that is accessible to patients, visitors, and staff. Conceptually, the location above clinical space spawned a design strategy that incorporates the Roof Garden into a larger exterior space, visually minimizes the massive 115,000 SF Operating Platform footprint, and connects to the Reading Museum adjacent to the site. Technical challenges, costs, and maintenance became the team’s primary focus once the design goals were established. As the complexity of the Healing Garden grew, so did the structure to support it. Investigation of design and material changes ultimately enabled the clinical space below to have an inhabitable ceiling height. Concerns from clinicians, facility personnel, and insurance underwriters required detailing that had redundant functions, but ultimately, the use of new technologies and materials created a solid building envelop that satisfied all concerns.


1. Illustrate the experiential impacts of a green roof
2. Establish green roof design process and possibilities
3. Explain green roof technical implications to building envelope design
4. Identify common requirements of green roof design and documentation
