This project proposes to implement a 30,000 gallon rainwater harvesting system and/or a teaching green roof for the new Edward St. John Learning and Teaching Center (ESJ LTC) at the University of Maryland, College Park. The project is currently in the design phase, and the building is scheduled to open summer of 2016. The new building will occupy a key location on the McKeldin Mall at the heart of the campus. It will incorporate the renovation of nearby Holzapfel Hall and proposes an addition to replace the existing Shriver Lab. The building is designed to earn a LEED Silver rating at a minimum with a goal of achieving LEED Gold certification.
The proposed rainwater harvesting system will be designed to collect rainwater from the roof of the building and re‐use it to flush toilets and urinals. The goal of the rainwater harvesting system is to reduce the building’s burden on the municipal water supply while working towards the idea of a self-sustaining building. It is estimated that this system will reduce the domestic water usage of the building by approximately 900,000 gallons per year.
The proposed teaching green roof will be a student accessible vegetated roof for teaching purposes. The opportunity to allow students to directly engage in hands-on experiments on a living green roof is integral to the active learning approach. The green roofs themselves can be incorporated directly in the undergraduate laboratory curriculum.
