Overview

   Introduction
   LEED Rating Systems
   Selecting the Team
       Architects / Engineers / Contractors
       LEED Accredited Professionals
       Commissioning Agents
   How can I learn more?
The Obligatory Green Images
Influential figures in green building

   US Green Building Council
     Multi-disciplinary group administering Leadership in Energy and
      Environmental Design (LEED) Rating Systems
   2030 Challenge
     Organization championing Carbon Emission Reduction through a
      strategy of green buildings and renewable energy
   ASHRAE
     Engineering association setting HVAC standards which are
      referenced by green building rating systems
   Build It Green
     California non-profit that administers residential program called
      GreenPoint Rated
   California governments with green building programs
     Dozens of cities and many counties with stand alone or
      referenced standards
Why do we need rating systems?

   To drive market transformation
   To have national / local benchmarks of best
    practice
   To create a baseline for comparison
   To create designation that is a reliable brand for
    consumer choice
   To provide an evaluation tool, not an end goal
   LEED Systems, Green Point Rated, Energy Star
Criticisms of LEED Rating Systems

   Still Valid:   (Continued evolution of systems needed)

       Not specific to my region’s climate
       Some credits are against code where I live
       LEED doesn’t go far enough
       Checklists encourage credit chasing
   No Longer as Valid: (Market has changed over last 5 years)
       Materials cost more
       Certification costs are too much
       Automatic markup in construction
Risk or Opportunity?

   Green Building is a Risk
    Management Strategy
       Oil Prices
       Electricity Access and Prices
       Potable Water Access

   DOE EIA projects significant
    creation or renovation of total US
    building stock over the next 30 years

   Green Building as a Opportunity
       Facility master plans can leverage
        annual maintenance budgets
       Transportation providers who adapt
        to the changing built environment
        they serve will stay relevant

Costs to registering a LEED Project

   Registration Fees:
    USGBC Members $450.00
    Non-Members   $600.00
   Initiation fee used to support and gain access to LEED
    Online – USGBC administrative software for completing
    process used by all team members
   USGBC now gives rebates to projects which achieve
    Platinum certification
What are the baseline requirements?

   Prerequisites are all or nothing, missing one
    disqualifies project
   Prerequisites for LEED for New Construction
       Construction Activity Pollution Prevention (SS)
       Fundamental Commissioning of the Building Energy
        Systems (EA)

How does a building get certified?
   Entire process is now done through online interface
   Register project with USGBC
   Determine Owner’s Project Requirements and Basis of Design
   Design project, determine credits – not an absolute scale
   Certification submission can be done in one or two phases, after
    design and after construction, or all after construction
   Standardized templates for each credit filled out by team members
   Reference guides help instruct how to complete
   LEED APs come in handy
   Submission of electronic documentation, USGBC reviews 1-2
    months, appeal if necessary
   No onsite “inspections”
   Certification Levels: Certified, Silver, Gold, Platinum
What does it cost to certify a LEED Project?
                                               Less than 50,000       50,000-500,000          More than

LEED 2009

   A LEED is being updated in 2009
       LEED credit values are undergoing a scientifically grounded weighting
        exercise that allocates points to credits based on the importance of the
        environmental benefit realized by achievement of the credit
        requirements.
   Credit Changes of a Significant Nature
       A new Water Use Reduction prerequisite and increased incentive for
        Water Use Reduction credits
       Expanded options for Heat Island Effect-Non Roof materials
       Inclusion of permanent monitoring system for Thermal Comfort
       Alignment and clarification of Daylight and Views requirements
       Increased Minimum Energy Performance prerequisite and credit
        requirements and update to ASHRAE 90.1-2007
       Increased incentive for On-Site Renewable Energy

   Building Your Green Building Team:

   LEED Accredited Professionals and
   Commissioning Agents
Starting the LEED Process
What to look for in AEC team

   Recent changes in technology and building industry
    practices should have owners looking for the
    following:
       LEED AP in each discipline if you are going for certification
       A/E using Building Information Modeling
       Energy and Carbon Assessment Modeling capability using
        programs such as Virtual Environment, Green Building
        Studio and Ecotect
       Integrated Project Delivery – Involving all stakeholders and
        team members from early in the process in a highly
        collaborative manner
What is a LEED AP?

   AP = Accredited Professional
   43,000+ APs in the world
   LEED Professional Accreditation distinguishes
    building professionals with the knowledge and
    skills to successfully steward the LEED
    certification process
   They passed a written exam about a paperwork
    process
What a LEED AP is not…
necessarily


   An expert on sustainability, carbon neutral
    design, renewable energy, etc.
   Someone with training in building design,
    engineering, facility management or
    environmental issues
   A fluent educator in green concepts
   Tree hugger
   An expert at every rating system or building type
Why do you need an AP?

   Gets your project a LEED point
   Choose the right rating system
   Oversees process of A/E team, owner, contractor to
    ensure understanding of rating system
    requirements.
       Could be third party person, or could come from any
        member of the ownership, design or construction team
   Well versed in synergies and tradeoffs between
    credits which need to be evaluated during process
   Intimately familiar with how to fill out key documents,
    and can help with BOD, OPR, Innovation Credits
Why would you hire a Cx Agent?

   Do you know what you are getting for your money now?
   Commissioning ensures you are getting what you paid for – the
    guarantee
     Assures of quality

     Assures specified deliverables

     Looks out for O&M from start to finish

     Meets designed operating efficiency

     Reduces contractor callbacks

     Reduces professional liability losses

   Oversees design and construction of all engineering systems to
    make sure they work with each other properly
   Link between designers, contractor and operator
   Helps with training and startup of system
   Increases actual energy efficiency performance, reduces utility
    demands, creates better indoor air quality and comfort
Typical Costs of Cx by size
   An Initial Rule of Thumb Based on MEP Cost
     2-3% of mechanical construction cost plus

     1-2% of electrical construction cost

   A Rule of Thumb Based on Construction Cost
     Project less than $30M - 1.25-2% of Total Cost

     Project $30-$50M - 1% of Construction cost

     Project more than $50M - 0.5-1% of Total Cost

     An average cost for Universities is 1% of Total Construction Cost

     Labs cost more to commission; spec office buildings cost less

   On a square foot basis
     Commissioning costs can run from $0.50 - $3.00

     Retro-commissioning can cost from $0.10 to $0.50/SF, and
      infrequently as high as $1.00/SF
Okay, but do I really need to hire these extra people?
(Why aren’t I already getting these services from the people I normally hire?)


   Cost cutting by AEC in the past led to sloppy end of project
    procedures and quality control
   Quality Control = Paper Trail
   Particularly critical while industry is changing models of
    delivery, technology is changing, and not everyone has done
    green building
   AP and CxA provide holistic view of project not yet typical
   Reduces certification audits, O&M problems later
   Green must be integral to the process, not tacked on late or
    considered ‘extra’ - otherwise you will see cost premiums
   Some value will be lost if not included from the beginning
 Types of Commissioning Services
              Commissioning                        Retrocommissioning                   Recommissioning

   LEED not LEEDS (it’s not a city in the UK)
   Projects are certified (Certified, Silver, Gold, Platinum)
   People are accredited (AP)
   The E’s stand for Energy and Environmental
   Required for all LEED projects are the
       Basis of Design - BOD
       Owners Project Requirements - OPR
   There are several different LEED systems, they
    each have different credits and prerequisites, but
    follow the same six general categories
    (except Existing Buildings and Neighborhood Development)
