When planning a new library building or upgrading an existing one, could you add a green rooftop? A green roof is a multi layer roofing system, an extension of the existing roof, with waterproofing, a root-repellent membrane system, a drainage system, and a multitude of plants that grow on top of a building. Many credits toward LEED Certification (from my previous post) can be earned by building green rooftops.
Green rooftops have been established in Europe for centuries due to both private and public benefits. Private benefits include cost savings (green roofs are estimated to last up to twice as long as conventional roofs AND provide savings on energy heating/cooling costs), sound insulation. (4.7″ layer can reduce sound by 40 decibels), and to provide food production (grow your own food for employees and events). Public benefits include economic (increase green jobs and products markets), improved air quality (reduce airbourne particulates and increase oxygen), temperature regulation (reducing the urban heat island effect), water (natural storm water retention and filtration), social (aesthetics, health, recreation, and horticulture), and preservation of habitat & biodiversity (native flora, fauna, and habitat… and education!).
Libraries could offer events, children’s programing, luncheons, evening concerts, meeting space, and relaxing reading spaces on their green rooftop. For urban libraries, this can be especially welcoming.

WHAT: Online, live discussion and place to share ideas about green libraries and campuses.
WHEN: Wednesday, May 14, 2008, 1:00 p.m. (Eastern), 30-45 minutes.
CONVENERS: Mary Carr, Dean Instructional Services, Spokane Community College and Dr. Debra Rowe, President of the US Partnership for a Sustainable Future
DISCUSSION QUESTIONS: From a library/librarians’ perspective, how are our library resources when it comes to sustainability? Are we supporting the college’s curricular efforts? What about the “greening” of the library and the campus? Can we practice sustainability? Can we promote it by speakers, presentations, etc.? What can we do within our library associations, and other professional groups? The whats, whys and wherefores of sustainability? What is happening on our campuses and in our communities regarding sustainability? How can we support what is happening and how can we contribute to moving the needle?
IMPT NOTES: ACRL OnPoint chats are free and open to the public. Sessions are unmoderated, 30 to 45 minutes long, and take place in a Meebo chat room. While no registration is necessary to participate, ACRL recommends creating a quick and easy Meebo account for the best experience while participating in ACRL OnPoint discussions. Full details are available on the ACRL Web site at www.acrl.org/ala/acrl/acrlproftools/OnPoint/onpoint.cfm.
Are you building or remolding your library? Check out Leadership in Energy and Environmental Design (LEED) Green Building Rating System. It’s a “third party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings.” (LEED Rating System Info) LEED looks at 5 areas: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.
For new construction check out LEED for New Construction. There are 4 levels: certified, silver, gold, platinum (levels are according to how many points you are awarded for meeting criteria in design, operations, construction and management). There is also specific LEED Certification for K-12 school (which can included higher ed)
Why LEED? There are environmental and financial benefits to getting certified green building (from LEED certification site):
- Lower operating costs and increased asset value.
- Reduce waste sent to landfills.
- Conserve energy and water.
- Healthier and safer for occupants.
- Reduce harmful greenhouse gas emissions.
- Qualify for tax rebates, zoning allowances and other incentives in hundreds of cities.
- Demonstrate an owner’s commitment to environmental stewardship and social responsibility.
Read this article/study which shows LEED Buildings Outperform Peers for more info. The US Green Building Council Web site also provides many resources, details, templates, guides, and tools that would be a great help when considering LEED certification.
You also don’t have to be constructing a new building to go green. Here is an article on how to take existing buildings and transform them into LEED for Existing Buildings Certification (for Operations and Maintenance).
