Optional Fields
The Rice University EcoReps host an annual Green Dorm Initiative (GDI), a three-week campus-wide competition each spring semester that encourages Rice students to adopt a more sustainable lifestyle. Each day student participants are presented with a new daily challenge, along with background information to explain the environmental benefits of a change in habits related to that challenge. Each week of the competition also features a week-long challenge. Prizes were awarded based on either participation or performance. One of the categories of the 2016 challenges was water and energy.
A brief description of the institution's water recovery and reuse initiatives:
Condensate harvesting: Air conditioning systems provide a constant source of clean, cold water that is well suited for reuse. With the opening of the BioSciences Research Collaborative (BRC) building on July 1, 2009, Rice began capturing condensate water from the air conditioning systems of that building to use as make-up water in the cooling towers of the South Plant. This is a free source of water that Rice would otherwise have to buy from the City of Houston. During the summer of 2011, Rice completed a project to capture condensate water from many of the science buildings to bring back to the Central Plant's cooling towers. Combined, these systems are estimated to save at least 12 million gallons of water per year, which is equivalent to about 5 to 6 percent of Rice's annual water consumption in a typical year. However, since these projects are not metered, we've not attempted to include them in the data for this credit.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):
There are hundreds of low-flow toilet fixtures on the Rice campus, and the facilities building standards now requires low-flow fixtures for toilets and urinals as well as efficient faucets for sinks. https://facilities.rice.edu/sites/g/files/bxs1011/f/22%2040%2000%20Plumbing%20Fixtures.pdf

Data source(s) and notes about the submission:
Baseline year data is from the fall of 2011
Performance year data is from July 1, 2014 to June 30, 2015.
Note: We considered the number of beds to be a proxy for the number of on-campus students. While the number of students living on-campus changes constantly during the year, the number of beds is stable each semester.
Note: In order to calculate the area of vegetated grounds we used the area from the baseline year and added the area of a newly built irrigated lawn.
