Xavier’s first ever green roof is located above the Hoff Dining Commons at Bishop Edward Fenwick Place. In addition to being a great place to study, host events or simply hang out, the green roof offers many sustainable features that improve Xavier’s relationship with the natural environment.
Storm water Management: With green roofs, water is stored by the substrate and then taken up by the plants from where it is returned to the atmosphere through transpiration and evaporation. Green roofs reduce the amount of storm water runoff and also delay the time at which runoff occurs, resulting in decreased stress on sewer systems at peak flow periods. Green roofs not only retain rainwater, but also moderate the temperature of the water and act as natural filters for any of the water that happens to run off.
Heat Island Effect: Through the daily dew and evaporation cycle, plants on vertical and horizontal surfaces are able to cool cities during hot summer months and reduce the Urban Heat Island (UHI) effect. The light absorbed by vegetation would otherwise be converted into heat energy. UHI is also mitigated by the covering some of the hottest surfaces in the urban environment – black rooftops.
Improved Air Quality: The plants on green roofs can capture airborne pollutants and atmospheric deposition as well as filter noxious gases.
