Executive Summary
Over the last decade, green buildings saw monumental growth. This trend is
expected to continue as green building principles and practices becoming integrated
in main-stream architecture and engineering communities, as well as in facility
operations and maintenance. According to McGraw-Hill Construction, “green building
will continue to grow over the next five years despite negative market conditions to
be a $96-$140 billion market.”1 Much credit goes to the U.S. Green Building Council
as its efforts have largely driven the charge to a more efficient and sustainable
future for the built environment. USGBC’s Leadership in Energy and Environmental
Design Green Building Rating Systems are instrumental tools, providing roadmaps tosustainability for building project teams as well as operations and maintenanceteams.
For building projects pursuing LEED certification, industry suppliers have an
unprecedented opportunity and a unique role to play, bringing technology, products
and systems to bear as part of solutions that achieve efficiency and sustainability.
EnOcean technology offers unique features and advantages, and it is very relevant tomany aspects of LEED. While technology, products and systems alone cannot achieve
LEED credits, EnOcean technology may apply to many LEED credits in the following
categories:
Sustainable Sites: Measurement and tracking of light levels
Energy and Atmosphere: Components of energy efficient HVAC and lighting
systems
Indoor Environmental Quality: Sensors and devices to support high quality
indoor environments
Innovation in Design or Operations: Innovative technologies and products to
support innovative solutions, or to take solutions to exemplary levels of
performanceThis document is intended to serve as a roadmap to LEED for the EnOcean
technology supplier, providing the following foundational elements:
Overview of LEED, including recent developments and trends
Application of EnOcean technology to LEED 2009
For New Construction and Major Renovations
For Existing Buildings: Operations and MaintenanceApplication concepts and considerations
Project profiles highlighting EnOcean technology’s contribution tosustainability and LEED certification
Finally, it is important to keep the broader picture in mind: EnOcean technology
applied in the pursuit of LEED certification may also help to deliver on energy andoperational efficiency, enhanced productivity and comfort, and sustainability inbuildings over the long term.

Introduction
The U.S. Green Building Council produced the first LEED, or Leadership in Energy andEnvironmental Design, Rating System in 1998. Since then, LEED experienced
dramatic growth in terms of projects adopting the rating systems and seeking
certification. Along the way, USGBC continues to expand and refine the LEED systemwith new and revised rating systems, documentation systems and supporting
publications and training programs.
For any given building project pursuing LEED certification, there are perhaps manypotential opportunities to bring technology to bear in solutions that support LEED
certification and sustainability. This document is intended to provide an overview of
how EnOcean technology may contribute to such building projects.

Overview of LEED
Some background on the LEED rating systems may prove helpful before looking at
technology applications to support LEED. Four basic aspects of the USGBC LEEDGreen Building Rating Systems serve as a foundation:
Levels of certification
Rating systems
Rating system structure and credit categories
Process for LEED certification

LevelsThere are four possible certification levels, and they are listed in Table 1. The morepoints a building project attains in the process of LEED certification, the higher thelevel of certification. Basically, points are achieved by proving that a building’s design
and/or operation meet the intent of a given credit.

Systems
At the inception of LEED
only one rating system
existed: LEED-NC, for new
construction. Over the lasttwelve years, USGBC has
introduced additional
rating systems that
address specific building
types or project scenarios.
It is important to note that
there is some variation
among the rating systems
in terms of credit content
and points available percredit category or per
credit. Figure 1 provides
an illustration of thevarious rating systems.

Process
Finally, LEED certification is a process with the resulting certification applying to abuilding. It is important to note that only buildings can be LEED certified, and thecertification does not apply to products, systems, or processes. The overall process is
illustrated in Table 3 below.

Key aspects of the process to keep in mind are as follows:
Typically, one or more LEED Accredited Professionals leads the team andguides the certification process for a given project.
The best results for green building projects appear to be achieved throughcollaboration, where integrated teams of architects, engineers, various
designers, construction managers, contractors, and suppliers, and otherprofessionals work together to attain a common goal.
There are substantial documentation requirements associated with theprocess, with an online system to facilitate documentation.
Perhaps most importantly, note that products can help achieve credits bybeing part of a solution that earns LEED points, but that products alone do
not earn points.
There are a few things that suppliers can do to assist the team’s efforts:
Become a part of the team. Work with the team to address challenges andidentify solutions. The solutions lead to opportunities to apply technology,
products and systems.
Educate the team on how products and systems contribute to specific credits
and attainment of LEED points.
Provide tools for the project team that facilitate design and documentation.

Recent Developments and Trends
Under USGBC the LEED green building
certification system continues to evolveand to see broader application. LEED
Version 3, launched in April of 2009,
offers the latest advancements to the
LEED Rating System (known as LEED2009) in combination with improved
online tools and a new certification
model.

Figure 2: LEED project registration andcertification trends

Continued Growth and Development
Data available from USGBC illustrates
strong continued growth in LEED
projects in both registrations andcertifications, as illustrated by Figure 2.
Early on, LEED offered a very strong
focus on new construction. However,noteworthy evolutionary trends ofparticular interest for LEED andassociated technology applications
include a growing emphasis on thebuilding lifecycle well beyond
construction with much greaterattention placed on two key aspects:
Energy efficiency and carbon
emissions impacts of buildings
Operations and maintenance
Energy Efficiency
First, in addition to improved alignmentof credits across rating systems and theintroduction of regional priority credits
to account for region-specificenvironmental issues, LEED 2009 offers
revised credit ratings such that it “nowawards more points for strategies thatwill have greater positive impacts onwhat matters most – energy efficiency
and CO2 reductions.” Earlier LEED
Rating Systems did not offer thisemphasis on energy efficiency, and as aresult, LEED certified buildings vary inenergy performance across a spectrum.
A study completed by the New Buildings
Institute in March 2008 illustrated thisphenomenon, and Figure 2 shows“median EUIs by certification level andthe individual measured EUIs for eachof 100 participating buildings, excluding

those consisting of high energy activity types such as labs, data centers andsupermarkets”.2
Figure 3: Energy Use Intensity (kBtu/square foot) for LEED Certified
Buildings3

Source: New Buildings InstituteThe revised credit weightings address this issue, and a comparison of LEED-NC (forNew Construction) version 3 with its predecessor version 2.2 readily illustrates theincreased emphasis on energy efficiency: While LEED-NC version 2.2 made 17 points
available for Energy & Atmosphere credits out of a total of 69 points, LEED-NC 2009(version 3) makes 35 points available for Energy & Atmosphere credits out of a totalof 100 points, a 42% increase in points available for credits associated with Energy &Atmosphere.
It is also important to note that this increased emphasis on Energy & Atmosphere
was addressed first for existing buildings with the introduction of LEED for Existing
Buildings: Operations and Maintenance, issued in January 2008, with 30 out of 85
points available for Energy & Atmosphere. The proportion of points available under
Energy & Atmosphere is unchanged in LEED 2009 for Existing Buildings: Operations
and Maintenance, where 35 points are available out of 100 total points.

Enabling Sustainability
Another important aspect of LEED for Existing Buildings: Operations and Maintenanceis its implied acknowledgement of the following:
The opportunity for existing buildings to contribute to energy efficiency andsustainability far outweighs that of new construction.
In order for a green building to remain green, proper and consistent operationand maintenance practices over time are vital.
Along the lines of the second point, recognizing the gap in LEED rating systems toensure energy performance over time, USGBC announced the Building Performance
Initiative in August 2009. This initiative’s charter is to collect data from all LEEDcertified buildings with the intent to conduct performance analysis and provide
feedback to owners, and it complements the announcement earlier in 2009 that
requires ongoing performance data from buildings as part of their certification under
the latest version of LEED.4
These evolutions in LEED around energy efficiency, existing buildings, and operations
and maintenance place greater emphasis on the performance of buildings over time,and also create and expand opportunities to apply technology to not only facilitate
the achievement of LEED , but to deliver on sustainability in buildings over the longterm.

Buildings and Opportunity
Existing Buildings

Table 4: Existing building statistics

There is a broad base ofexisting commercial buildings,
4.9 million in the U.S. alone5,and a large volume of new
facilities constructed annually.
While most of the industry
press appears to focus on thenewest and greenest ofbuildings, the industry itself isslowly turning its attention to
the existing building stock as amassive opportunity to cut
energy consumption andgreenhouse gas emissions.

In addition to representing
such a massive opportunity tosave energy and reduce greenhouse gas emissions, the existing building stockpresents a corresponding massive opportunity to apply technology as a means tothose ends. Wireless technology is of particular interest with its flexibility from bothinstallation and operational perspectives.

Application of EnOcean Technology to LEEDLEED 2009 For New Construction and Major Renovations
In the LEED 2009 For New Construction and Major Renovations rating system, there
are a number of opportunities to apply EnOcean technology in pursuit of points. The
credit categories that present the greatest potential are:Energy and Atmosphere
Indoor Environmental Quality
Innovation in Design
Considerations when seeking potential to apply EnOcean wireless technology tosupport the achievement of LEED in a new construction scenario converge on several
central themes:
Commissioning
Monitoring, measurement and verification
Energy performanceControllability
In addition, there is the opportunity to propose an innovative approach that may not
fall under existing credits in pursuit of points available under the Innovation in
Design credit.
It is also important to note that the information presented here for the LEED 2009
For New Construction and Major Renovations rating system also applies to credits
within the following rating systems:
Core & Shell
Commercial Interiors
Schools
The following three tables provide a set of tools to navigate the LEED 2009 For New
Construction and Major Renovations rating system and to facilitate identification ofopportunities to apply technology in support of LEED certification.
Table 5 shows the relevant credit categories with their associated available
points.
For each credit that presents an opportunity with regard to EnOcean wirelesstechnology, Table 6 indicates which applications are most appropriate. For
example, for EA Credit 1 Optimize Energy Performance, EnOcean technology
applies across the board to all of the applications; whereas, for IEQ Credit 6.1
Controllability of Systems – Lighting, EnOcean technology only applies to halfof the applications.
Table 7 indicates the number of possible points for each of the credits where
EnOcean technology may apply, and it summarizes how the technology may
impact and/or contribute to achievement of each credit’s intent.
For additional discussion of the credit categories and greater depth on potential ways
to apply EnOcean technology, see the section Application Concepts & Considerations.

LEED for Existing Buildings: Operations and Maintenance
Opportunities in the LEED 2009 for Existing Buildings: Operations and Maintenancerating system expand relative to the LEED 2009 For New Construction and Major
Renovations, with major provisions focused on existing buildings centered on a
handful of key themes:
Monitoring, tracking and reporting of water use, energy use, space conditionsand ventilation, and emissions
Occupant education
Oversight and execution of re-commissioning and continuous commissioning
Understanding of metering, energy data acquisition and analysis
Thus, in a general sense, there are numerous opportunities for application of wirelesssensing and measurement. Relative to the New Construction rating system, morecredit categories present potential for EnOcean technology:
Sustainable Sites
Water Efficiency
Energy and Atmosphere
Indoor Environmental Quality
Innovation in Operations
Also, similar to New Construction, there is the opportunity to propose an innovative
approach under the Innovation in Operations credit.

For each of the credit categories in the LEED rating systems, the following sections
discuss application concepts and considerations. Of course, in addition tocontributing to satisfaction of LEED requirements, wireless solutions offer flexibility
and the potential for lower installed cost, both very positive attributes in their own
right.

Existing buildings may offer more opportunities than new construction to apply
technology in the name of energy efficiency. But, in all cases, some general themes
apply:
Commissioning: Requires measurement of all types of parameters, including
temperature, humidity, pressure, flow, lighting levels, and so on. The key is
to seek opportunities where a wireless solution may offer advantages insensing and measurement for both commissioning and on an ongoing basis.
Measurement and Verification: Measurement of energy is the name of thegame here, and all types including electricity, natural gas, other fuels, steam,and hot or chilled water. The Measurement and Verification Plan for the
project is the place to start when identifying opportunities.
Energy Performance: A large number of points are available for energy
performance based on the level of performance sought. Many opportunities
may be available as part of the solutions required for high levels of energy
performance. Some of the concepts and strategies apply primarily to HVAC
and lighting and may include, but are not limited to:
Ventilation control, including demand control ventilation
Heat recovery
Variable-air-volume control, including supply air temperature reset
Radiant heating and cooling
Evaporative cooling
Economizer control
Variable speed control

Next to Energy and Atmosphere, Indoor Environmental Quality is the next largest
opportunity to put technology to the task.
Ventilation: Monitoring of outdoor air delivery (flow rates) and CO2 levels are
key to ventilation and indoor air quality under LEED. Verification: For IEQ,
verification refers primarily to thermal comfort parameters such astemperature and humidity.
Control: In general, LEED encourages greater degrees of control overpersonal environments, both in terms of thermal comfort and lighting.
History: As for Energy and Atmosphere, for the above considerations, it may
be necessary or beneficial to log measurement data over time. This isespecially true of data relevant to space conditions.
Note that some facilities may also require monitoring of other parameters
associated with indoor air quality, such as volatile organic compounds, mold,dust, and other contaminants that may adversely impact people occupying thespace.

Innovation

Innovation in Operations

Finally, innovative applications that do not apply directly to existing LEED credits orthat dramatically enhance sustainability may serve as a basis for innovation credits.
Exemplary performance under an existing credit is another path to innovation credit
points.
