4 tips on LEED
1. How to Use LEED-CI
Today's tip is about the LEED for Commercial Interiors rating system. If you manage tenant space, now is a good time to take a look at LEED-CI before the rating system changes next June.
One of the more surprising things about LEED-CI is that you can get up to 37 points for energy efficiency strategies in tenant space. Tenants often assume there isn't much that can be done about energy use in their space, but LEED-CI provides a good blueprint for ways to be efficient — including lighting power, lighting controls, enhanced commissioning, and buying green power. Like most LEED-CI strategies, at the very least, the energy efficiency category provides a good opportunity to have a conversation with the owner, landlord and property managers about what can be done to reduce energy.
The next most points-rich category is sustainable sites, which again seems a bit illogical, since tenants are more or less locked into their sites. But this category provides points for strategies like access to public transportation - which means, if tenants have LEED-CI certification in their future plans, it behooves them to pick a building near such public transportation. But tenants also earn points for bicycle storage and changing rooms and parking availability.
Using sustainable materials and resources, including materials that enhance indoor air quality, in the tenant build-out is also a key way to earn LEED-CI points. Use certified wood, materials with recycled content, and paints, adhesives, flooring systems and systems furniture that meet acceptable levels of low-VOC emissions.
Ultimately, success or failure with LEED-CI comes down to a careful cooperation between the tenant, its occupants and landlords and property managers. But securing a sustainable tenant space can be a good way, as studies are increasingly showing, to attracting and retaining the top talent.
2. What is LEEDv4?
Today's tip is about the update to the LEED rating system that had been due out in late 2012. The new suite of LEED rating systems, which had been in development for more than three years, had garnered more than 20,000 comments during three public comment periods.
The rating systems were expected to be a significant step forward in terms of sustainable strategies for both new and existing buildings. But, according to the U.S. Green Building Council president, CEO and founding chairman, Rick Fedrizzi, "we have heard repeatedly that while our community continues to fully embrace our mission, they need more time to absorb the changes we're proposing and to get their businesses ready to take the step with us."
So LEED 2012, as it had been previously called, is being renamed LEEDv4 and is being delayed until June 1, 2013.
One of the provisions of the new LEED that has elicited some of the strongest opinions is the new prerequisite in LEED-EBOM that a project have a minimum Energy Star score of 75. Some feel that requirement is too stringent.
Additionally, USGBC added an "alternate compliance path" for achieving that prerequisite such that if a building can't achieve 75, but can show 20 percent year-over-year energy improvement, it can still achieve a Certified rating. However, no matter how many other points it achieves in other categories, Certified is as high as that building can be rated.
As USGBC continues to hear from its members and the public, and continues to work on complementary materials and reference guides for the new rating system, expect to hear much more about the changes.

3. LEED: Ensuring Long-Term Performance
I'm Dan Hounsell, editor of Maintenance Solutions magazine. Today's topic is, LEED and long-term performance.
When maintenance and engineering managers are involved in designing, constructing, and operating a new facility, there is a great deal to learn along the way. But when the facility is pursuing never-before-seen green building goals, managers can expect a much steeper learning curve. Perhaps nobody understands that better than Jeff Schorzman, facilities manager with Providence Newberg (Ore.) Medical Center.
In a way, Schorzman went back to school as he helped the 183,000-square-foot facility become the first hospital to earn Gold certification under the Leadership in Energy and Environmental Design (LEED) rating system. But Schorzman's education did not end when the hospital came online in June 2006. Instead, he has kept learning about the building and its state-of-the-art technology.
Despite the advanced technologies Schorzman and his team specified for the new facility, the medical center did not perform as designers intended during its first year of operation. One reason the facility struggled initially was that the project team tried to meet tight deadlines without sufficient vetting of the systems.
"I know you get bumped up against schedules, but folks really need to incorporate into their schedules time to wash the systems out," he says. "We did commission the building, but we were pushed, and we were rushed. You really need to give yourself time to work through the issues and drive the boat."
Another cause of inefficient operation related to oversized equipment.
"Our steam system in the building was sized for humidification for the whole building 24/7, and our sterilization of surgical instrumentation 24/7/365," he says. "The majority of our surgeries are done Monday through Friday between 6 a.m. and 6 p.m. The only areas that require humidification are the surgery areas, so (the system was) oversized."
Schorzman and his staff went through trial and error during the first year of operation, but now, systems are performing as the project team intended. Power use is down 12 percent, compared to the first year, and gas use is down about 30 percent, Schorzman says. Technicians are constantly making tweaks and improvements, but five years after becoming the first LEED Gold hospital, he can look back at this learning experience as a positive one.
4. What is the STARS Rating System?
Today's tip is about a green rating system developed by the Association for Advancement of Sustainability in Higher Education called STARS — an acronym for Sustainability Tracking Assessment and Rating System.
STARS is a way for colleges and universities to track and measure their sustainability performances. The self-reporting tool is available to any college or university in the United States or Canada. The system provides environmental, social and economic indicators in three categories related to campus activities. Those are: Education and Research; Operations; and Planning, Administration, and Engagement. Each of these categories includes subcategories such as Purchasing, Curriculum, Energy, and Human Resources. There is also an Innovation category to recognize pioneering practices that aren't covered by other STARS credits. Similar to LEED, points in each category are totaled and then a STARS rating of Bronze, Silver, Gold or Platinum. A Reporter rating means the institution wished the score to remain private.
The process to use the system is simple — first register online at stars.aashe.org. Then, identify your institutional boundary and begin collecting data. Submit a STARS report and receive your STARS rating.
Currently, there are 195 institutions participating in STARS, including the University of Dayton, St. Louis University, and the University of Notre Dame. The fee to use STARS is $900 if you're an AASHE member and $1,400 if you're not. Find more information about STARS at stars.aashe.org.
