Their company or organization and their role there
One thing they hope this class helps them understand about managing green projects]
B. Integrated approach
To understand:
Page 1
Understand construction’s environmental impact.
Understand the integrated approach that green building requires.
Know how to implement the procedures on a “green” construction site.
Some of the specific issues we will be discussing:
What’s a “green building”?
What you need to know that wasn't needed on conventional jobs (including LEED tracking and documentation).
What is the “Sustainability Team” and how will you interact with it.
How “green” jobs can have a different cost structure, new schedule constraints, and how they can be accounted for in your bids.
Why the comprehensive quality control checklist is key to a successful green project.
The importance of good communication with subcontractors, especially with new requirements and technologies.
How to conduct a useful post-occupancy review and assessment.
GPRO Certificate Holders
To become a G|PRO certificate holder, you must pass the 50-question certificate exam which will include questions from both this course and the Fundamentals of Building Green course.
[All students should have taken a Fundamentals course prior to this course. If they didn’t, please ask them to contact their delivery partner of GPRO (contact information is in the manual) before sitting for an exam.]
The short quizzes delivered throughout the manual will provide you with a sampling of the type of questions you will be expected to answer on the certificate exam.
Upon successfully passing the test, you will receive a GPRO Certificate, wallet card, and hardhat sticker for GPRO Construction Management.

Good construction management is critical on a green building. Managing a green project requires substantial knowledge of both the green building process and the documentation requirements of LEED. This specific green knowledge must be integrated with your knowledge of standard construction management best practices to achieve a successful project for your company and your building owner.
Let's start by talking about how sustainability affects construction management.
As we talked about in Fundamentals, sustainability is a way of living (and working) that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Sustainability is the integration of design and construction as related to:
Water conservation
Energy efficiency
Measures taken to reduce the use of materials and resources with the focus on the construction site rather than the design office
Healthy indoor air quality
LEED Gold Building, NY
A green building is designed, constructed and maintained to minimize adverse environmental impacts and to reduce energy consumption, while contributing to the health and productivity of its occupants.  
A key component is consideration of the building's impacts and performance over its entire life.
What is Green Building? Page 2
A Green Building
Let's review our definition of green building:
A green building is designed and constructed to minimize adverse environmental impacts, reduce energy consumption, and contribute to the health and productivity of both workers during construction and occupants after completion.
A key component is consideration of the building's durability and performance over its entire life.
However, these green building characteristics can create new constraints and requirements for the construction team.
There are different types of sustainable buildings:
High performing buildings are energy and/or water efficient.
Green buildings are high performing, use sustainable or recycled resources, and have good indoor air quality.
LEED Credit Categories:
Prerequisites for LEED
2. Water Efficiency p1: Water Use Reduction – 20%
3. Energy & Atmosphere p1: Fundamental Commissioning
p2: Minimum Energy Performance
p3: Fundamental Refrigerant Management
5. Indoor Environmental p1: Min. Indoor Air Quality Performance
Quality p2: Environmental Tobacco Smoke Control
Here's a list of the prerequisites for each LEED category.
Note that while not all green projects get LEED certification, we want you to be familiar with LEED terminology and requirements because it is the most comprehensive green building standard in the world. Failing to achieve a prerequisite can forfeit a LEED certification.
SSp1: CAPP: Intent is to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation, and airborne dust generation. (Construction issue)
WEp1: Water Use Reduction – 20%: Intent is to increase water efficiency within buildings to reduce the burden on municipal water supply and wastewater systems. 20% reduction is based on the U.S. EPAct and the Uniform Plumbing Code. Complying fixture flow rates are also listed in the LEED credit. (Design and construction issue)
EAp1: Fundamental Commissioning: Intent is to verify that the project’s energy-related systems are installed, calibrated, and performed according to the Owner’s Project Requirements, Basis of Design, and construction documents. (Design and construction issue)
EAp2: Minimum Energy Performance: Intent is to establish the minimum level of energy efficiency for the proposed building and systems. The project must establish an “energy performance rating goal” for the facility design using EPA’s Target Finder rating tool. (Design and construction issue)
EAp3: Fundamental Refrigerant Management: Intent is to reduce stratospheric ozone depletion by avoiding chlorofluorocarbons (CFC’s). (Design and construction issue)
MRp1: Storage & Collection of Recyclables: Intent is to facilitate the reduction of waste generated by building occupants that is hauled to and disposed of in landfills. Requirement is to include in the design an easily accessible dedicated area for collection of: paper, corrugated cardboard, glass, plastics, and metals (note: this is different from CWM). (Design issue)
IAQp1: Minimum Indoor Air Quality Performance: Intent is to enhance indoor air quality in buildings. Comply by meeting minimum requirements of ASHRAE Standard 62.1-2007, sections 4-7 AND provide adequate mechanical OR natural ventilation. (Design and construction issue)
Whole Building Approach
As we discussed in Fundamentals, the "whole building approach" recognizes that a building is a complex collection of interacting systems. These systems must be looked at together because achieving efficiency in one system might have a substantial effect on another.
For example, better insulation will reduce heating and cooling loads. However, using more efficient light bulbs may require more heating to make up for the waste heat from less efficient bulbs.
More importantly, in order to achieve efficiency across all the building systems, there must be detailed communication and coordination among all members of the construction team; this is called an integrated design process.
Leadership in Green Design
To successfully meet a project's sustainability goals, a green project may have these additional elements that must be coordinated among all the trades:
New technologies
Added verification
Greater coordination
There is more administrative effort required, but it pays off as a greener, higher performing building, a better understanding of the project's intent, and stronger relationships among the trades.
What green or sustainable practices are you already doing on your projects?
[Ask:] What is your experience with green projects?
[DISCUSS: Note that the students may have touched on their experiences in the introductions, but let's go a little deeper.]
[Ask:] What's your experience with managing a green project?
[Prompt with questions and/or you may ask for a show of hands:]
How many of you have worked on a LEED/green project?
How many of you are Green Associates? LEED APs? Or have worked with people with these certifications?
CM/GC's Roles Relating to Sustainability
This course simulates a timeline of a real construction project. In each chapter, we will discuss the actions a construction manager has to take that differentiate conventional buildings from green buildings on a phase-by-phase basis.
[Go through each phase listed on the slide with the class.]
This chart is in your manual on page 4.
How does the sustainability concept of integration affect the construction process and the CM/GC's role?
Page 4
Page 5
One important way green buildings differ from conventional buildings is that the contractor gets involved in the building process earlier, before construction even starts.
Pre-construction (pre-con) is a phase that used to only include the building owner and the design team. Now the construction team and operations team are invited to the design table to lend their expertise.
The CM/GC's participation can be extremely valuable in the early design stages and can lead to much smoother construction processes when the entire team has a good understanding of the owner's intent.
To help you understand how to better participate in the pre-con phase, we will discuss:
Who is part of the Sustainability Team and what are everyone's roles and responsibilities.
What is the process for establishing sustainability goals.
How potential LEED credits are determined and narrowed down to proposed credits.
What is the LEED Credit Scorecard.
The Sustainability Team
The Sustainability Team (abbreviated in the manual as ST) consists of everyone on the construction team who has a part in helping a project meet its sustainability goals.
The CM/GC is an important member of the Sustainability Team.
The team includes the owner, architect, engineer, CM/GC, and primary subcontractors. The sustainability manager, usually a LEED AP, defines the team structure and responsibilities of all team members and manages the filing of LEED documentation.
Case Study:
Fort Hamilton Historic Society
Maritime Museum, Brooklyn, NY
[HAND OUTDOC. 2.1: CASE STUDY (located at back of student manual)]
The Fort Hamilton Historic Society Maritime Museum overlooks Lower New York Bay in Brooklyn, New York, near the subway stations and bus lines.
Built as a warehouse in 1890, the Fort Hamilton Historical Society is renovating the building to house a collection of Early American maritime art and salvaged vessels.

Classroom Exercise #1 Pages 57-58
Defining the Sustainability Goals Pages 6-7
Defining Sustainability Goals
To build a green project, the first step is to define sustainability goals.
This is a job for the building owner and the Sustainability Team.
You may be part of the team that develops these sustainability goals.
This is the time to think "big picture" before having to respond to the project constraints.
For example, broad sustainability goals may include "30% more energy efficient than code" or "excellent indoor air quality."
Assess project potential for LEED certification
Identify possible measures & credits
Establish proposed sustainability measures
Determine feasible LEED credits
Confirm goals and credits
During the schematic design phase, the Sustainability Team will:
Assess potential for the project to achieve certification under one of the LEED rating systems.
Identify possible sustainability measures and LEED credits and do an initial point tally (we did this for you already – you'll see on the next classroom exercise).
Establish proposed sustainability measures after considering the project constraints. During the schematic design phase, the ST starts to determine which of the possible measures are the most feasible to achieve considering cost, owner's priorities, etc.
Determine which LEED Credits are to be targeted. This is where details start to be fleshed out.
Confirm goals and credits to the Owner and explain your thoughts about how the team will achieve its sustainability goals.
Case Study:
Proposed LEED Points
Review potential LEED points to determine which are feasible to proceed with.
[Have the students review the Sustainability Goals & LEED Credit Worksheet.]
We have pre-selected credits appropriate for this project so you don't need to spend class time deciding which credits to select.
[Talk about how credits are selected during the schematic design phase and what kind of work goes into backing up those decisions (this will be a class exercise following in the next chapter).]
The points shown in red are the ones being considered for this project.
For a LEED project to be certified, it needs:
Certified (lowest certification): 40-49 points
Silver: 50-59 points
Gold: 69-79 points
Platinum: 80-110 points
The shorter, the better!
Evaluating Costs to Prioritize Scope
During Schematic Design, the CM/GC has the valuable task of providing preliminary pricing information so that an accurate payback analysis can be performed.
Preliminary pricing is critical for developing the feasibility of and prioritizing of sustainability measures.
Simple Payback Analysis
Payback analysis lets us compare the first costs of an improvement to the savings that will result from that improvement.
Payback period = cost / annual operational savings
Return on Investment (ROI) =
annual operation savings / cost
the ROI for this example = $17,000 / $175,000 = 9.7%, which is pretty good compared to savings accounts or other recent investments.
These numbers are rough estimates of costs and returns and will vary by project and region.
Also, payback analysis, while useful, does not take into account the time value of money. If you spend extra money today, you can't use it for something else or gain interest on it.
Payback Analysis Comparison
ITEM (Column 1)
Chiller Variable Frequency Drive
There are a variety of ways to present information about payback analysis. The idea is to make the information as useful as possible so that the Sustainability Team can evaluate:
Which measures are most consistent with the design intent of the project and which are the best ways to satisfy that intent.
Whether there are situations where conventional practices are working against our goals.
If we are missing any opportunities for savings.
A comparative payback analysis is helpful in deciding which proposed measures give the best payback.
For each measure,
First calculate the additional cost (if any) of the proposed upgrade to the base design Additional Cost of the Upgrade (Column 3)
Subtract the amount of any available Incentive or Subsidy (Column 4) to get the Net Capital Investment (Column 5)
Calculate the Anticipated Annual Operational Savings (Column 6)
Green projects have less wiggle room.
Substitutions with lower "first costs" may cost a lot more in the long run.
During Value Engineering, green elements are often targeted for elimination due to high first costs, but this can impact a project's ability to achieve credits for a LEED certification. It may also affect the holistic integration of green strategies. Value engineering decisions should not be taken lightly and should be thoroughly analyzed by all parties to make sure that sustainability goals will be met with the proposed substitution.
Funding can come from local, state, federal or utilities
Factor funding into payback analysis process
A/E will rely on CM/GC for data and scheduling info
Analyzing Sustainability Incentives Page 11
Incentives Analysis
Incentives, rebates and tax credits are available for many sustainable strategies but the deadlines, criteria and dollar amounts are constantly changing.
What is the CM/GC's role on the Sustainability Team (ST)?
How is the CM/GC involved in identifying sustainability goals and target LEED credits?
Why and how do you conduct and evaluate a simple payback analysis?
What is the CM/GC's role in analyzing sustainability incentives?
Page 11
The CM/GC will be an active member of the Sustainability Team and coordinate the activities and involvement of his or her group or company.
The CM/GC reviews the schematic plans with the A/E team, gives advice on how sustainability measures impact construction costs and schedules, evaluates the A/E team’s proposed product selection, and reviews specifications and checks with suppliers, vendors, and manufacturers to confirm the constructability, availability, and cost of the project.
A simple payback analysis compares the first costs of an improvement to the savings that will result form the improvement. For each measure,
First calculate the additional cost (if any) of the proposed upgrade to the base design Additional Cost of the Upgrade
Subtract the amount of any available Incentive or Subsidy to get the Net Capital Investment
Calculate the Anticipated Annual Operational Savings
Divide by the Additional Cost of the Upgrade to get the Payback Period
Page 12
This course is set up to simulate the timeline of a construction project. This section interrupts that chronology so we can discuss the Sustainability Management Plan.
We'll talk about developing a Sustainability Management Plan (SMP) and learn how to use it to organize the green elements of the project.
We'll use it to:
Identify all the work practices and documentation required to achieve a high performing building.
Make sure all the trades are aware of their responsibilities.
Set up an inspection tracking checklist.
The Sustainability Management Plan (SMP) Page 12
TYPE 1: Mostly design team’s responsibility and design team verifies.
TYPE 2: Shared design team and construction team responsibility with construction team responsible for verification.
Types of LEED credits for use with the SMP:
Type 1 is mostly the design team's responsibility. Credits are identified, documented and filed by the design team in pre-construction. These require little follow-up by the CM/GC.
What trades are affected?
What are the documentation requirements and how will they be met?
What work practices are required and how will they be verified?
Create your Sustainability Management Plan
The Sustainability Management Plan (SMP) Pages 12-14
You will need to make sure the SMP and Quality Control Plan shows a specific methodology for integrating and accomplishing the sustainability goals, specifically:
Who is responsible for what?
What trades are affected?
Sustainability Management Plan
The CM generates the SMP to coordinate the execution of the sustainability measures.
[REVIEW THE BLANK SMP located at the back of the student manual)]
[Divide room into 8 groups of 2 to 3 people each. HAND OUT CREDIT DESCRIPTIONS.
Have the groups develop a SMP based on the credits they have received and report a summary back to the class. Note: A sample SMP is included in your instructor handout.
They should discuss:
Is this credit required or optional?
What has to happen in what phase to make this a successful strategy?
Which trades are affected?
What documentation is required?
Now make the argument to the Owner about how you plan to achieve each credit.
Classroom Exercise #3 Page 63
Make the argument to the owner about how you plan to achieve each credit.
[This will give the class a more in depth look at all the credits.]
[Have the Owner, Architect, Engineer, Sustainability Manager, and Tenant cards at seats at a meeting table. Have students take turns with the role of CM/GC to present their findings to the class. Encourage participants to ask questions that someone in their role would ask. For example, the Owner can ask how much things cost, the Engineer can inquire about when he will be needed during Cx, and the various subs can participate in discussions related to their roles (i.e., Painter or Millwork for low-VOC, Hauling/Waste Removal for CWM).]
Sometimes Points are Eliminated
Delete Solar Thermal System:
Financial criteria: Proposed solar system will have a long payback period (increasing water efficiency means less hot water being used)
Site logistics: Turns out that the solar thermal system doesn't have adequate southern exposure
As more information is obtained about the various strategies, sometimes proposed credits are eliminated. The LEED credit spreadsheet shows enough potential points to achieve LEED silver even without the 5 proposed points for the renewable energy credit.
