4  FM quick reads on LEED

1. The "Big Four" Green Building Rating Systems


Today's tip looks at four of the major green building rating systems available to facility managers: LEED, BOMA 360, Certification from the Society for Environmentally Responsible Facilities (or SERF), and Green Globes.

Let's start with LEED, easily the most familiar of the four. The U.S. Green Building Council's roster of LEED rating systems has grown dramatically since the first one - New Construction - came online in 2001. LEED is used all over the world to certify everything from data centers to synagogues, both new and existing buildings. The LEED rating systems is based on a 100-point scale and certification is awarded at four levels, Certified, Silver, Gold and Platinum. For more information on LEED, visit www.usgbc.org.

The green certification created by the Society for Environmentally Responsible Facilities is the newest kid on the block. It was founded in mid-2011, and according to its founder Joe Maguire, SERF certification aims to streamline the application and submission process, and reduce the time and money it takes for a building to be certified green. The process should take between four and six weeks. SERF certification can apply to a variety of building types, including office, multi-family residential and institutional. For more information, visit www.serfgreen.com.

The Building Owners and Managers Association's 360 Performance Program evaluates six areas of operations and management practices, including Building Operations and Maintenance, Life Safety/Security/Risk Management, Training and Education, Energy, Environment/Sustainability, and Tenant Relations/Community Involvement. As you can tell, it's a holistic building evaluation that moves beyond just green criteria. The certification only applies to occupied office building and industrial space. For more information, visit www.boma.org and search BOMA 360.

Finally, Green Globes is a rating system offered in the U.S. by an organization called the Green Building Initiative. Using an online questionnaire and evaluation tool, the rating system scores facilities on a 1,000-point scale in several categories. Green Globes can be used as a self-assessment tool, or, if owners prefer, they can hire third-party assessors to certify facilities. For more information, visit www.thegbi.org.


2.  LEED-EBOM 2012 To Focus on Performance

Today's tip of the day is about some of the major changes to look forward to when LEED EBOM is released in its newest version this fall. All of the LEED rating systems are getting overhauls, but it's the Operations and Maintenance rating system that has some of the biggest changes.

Most importantly, each LEED-EBOM credit and prerequisite is being rewritten to include two parts, an Establishment part and a Performance part. Facility managers will have to comply with both parts in order to earn the points for the credit.

The establishment portion of each credit is, as the U.S. Green Building Council explains, "static and foundational." It "establishes" the foundation for ongoing performance in the building, including strategies like installing meters and developing policies and procedures. As an example, in the draft version of LEED-EBOM, the Establishment portion of the Water Efficiency Credit for "additional landscape water use" requires users to calculate the baseline of current landscape water use and install a submeter to measure it.

The Performance portion of each credit, as its name implies, ensures that the Establishment portion of the credit is carried out in the real world. The Performance part of a credit is "dynamic and recurring," and includes strategies such as surveys, audits, and ongoing tracking. As an example, for the water efficiency credit mentioned early, to comply with the Performance part of the credit, facility managers must calculate the metered water use, and then are awarded 1 point if that use is 30 percent below a baseline of the average of the last three years, and 2 points if use is 40 percent below that baseline.

One of the goals of the dual-part credits in LEED-EBOM is to help reduce redundancy in the recertification process. Facility managers can more easily track each performance requirement and only submit that information for recertification, as opposed to have to start essentially from scratch to recertify.

3.  LEED-EBOM Now Most Popular Rating System

Today's tip is actually a bit of exciting industry news. As of December, 2011, according to the U.S. Green Building Council the square footage of projects certified with LEED for Existing Buildings: Operations and Maintenance, or LEED-EBOM, is now greater than that of projects certified by LEED for New Construction. EBOM has 15 million more square feet of certified space than does NC.

Historically, LEED-NC has been the rating system of choice, and has made up the overwhelming majority of LEED-certified green projects, both in volume and square footage. That was partially due to the fact that architects, more so than facility managers, had a tangible marketing benefit to showing they could design and build LEED-certified space. It was also due simply to the fact that LEED-NC had been available for several more years than LEED-EBOM had been.

But the tide began to turn in 2008, when LEED-EBOM began experiencing explosive growth. In 2009, projects certified under LEED-EBOM surpassed those certified under its new construction counterpart on an annual basis for the first time. This was a trend that continued in 2010 and 2011.

What's more, a McGraw-Hill study shows that commercial renovation and retrofit activity will more than triple by 2015. That represents a growth from 25 percent to 33 percent of construction activity by value, and a $14 to $18 billion opportunity.

4.  LEED-CI: Greening Leased Space

Today's tip is about how to use LEED for Commercial Interiors to save energy in tenant space. After a slow start in the marketplace, tenants are using LEED CI much more frequently these days to implement sustainable strategies in leased space. Conventional wisdom had been that tenants have very little control over their energy spend when they lease space, and therefore there was no reason to implement a systemized energy or sustainability strategy, outside of putting out a few recycling bins. But LEED-CI offers a framework for tenants who wish to be energy efficient and green.

LEED-CI offers 37 points (out of 100) for energy efficiency strategies. The area with the most potential impact for tenants is, believe it or not, HVAC. LEED-CI offers up to 10 points for optimizing HVAC performance. Because building-level HVAC is one thing tenants don't have control over, LEED-CI rewards tenants for implementing zoning and controls for their own space. There are several options available for achieve these points, including simply "demonstrating that HVAC system component performance is 15 or 30 percent better than ASHRAE 90.1- 2007."

LEED-CI offers up to seven points for reducing lighting power density up to 35 percent below the standard set in ASHRAE 90.1 - 2007. This can be done by using efficient fixtures, like T5s, or, as LEED CI suggests, using daylight responsive controls in spaces within 15 feet of windows and under skylight.

A third area for which LEED CI rewards tenants for energy efficiency measures is plug loads, like appliances. Four points are available for using 90 percent Energy Star-rated appliances, office equipment, electronics and commercial food service equipment. The credit excludes HVAC, lighting and building envelope products.

Finally, five points can be earned for enhanced commissioning.

LEED CI also offers 14 points for various materials and resources strategies, like recycling, and 17 points for indoor environmental quality strategies like selecting low-emitting materials. Sustainable sites strategies can get you 21 points and water efficiency strategies round out LEED CI with 11 possible points.
