Introductions

 

What preconceived notions about green building have you brought with you today?

• The north/south axis solar orientation presents a challenge
• Budget is a challenge because green can cost more
• Building needs to be functional and flexible, especially lighting
• Existing landscaping can be salvaged and reinstalled
• Backing off on water use in irrigation is a challenge
• Exhausted by process and looking for input

- Under floor air distribution system

• Can we get a LEED point out of the raised floor system
• Need to work with stormwater requirements (i.e. BES)
• Green building impact on the use and function of classrooms
• College has 3-4 LEED projects with each pushing further

- Opportunity to push the envelope

• Lewis & Clark Environmental Council

- Desire to push the envelope

- Something special in the building that people can talk about. The building is not a business and does not have to have a direct payoff.

- Think of the entire building as a tool for learning

• Life Cycle Cost (LCC)
• Upset the LCC scale and create green building that is cheaper and better
• High quality daylight in classrooms

LEED Scorecard

Sustainable Sites

1. SS Cr 2.0         Review campus density
2. SS Cr 4.2         Showers & changing available directly adjacent in Pamplin
3. SS Cr 5.1         Appalachia will be removed and area restored as native landscaping
4. SS Cr 6.1         Need calculations on impervious surface area
5. SS Cr 6.2         Swales will treat roof runoff
6. SS Cr 7.1         Light colored paving on walks and tree shading
7. SS Cr 7.2         Check reflectance and emitance of slate roof tile

Potential site innovation points and other green measures

• New building will allow the removal of less efficient existing buildings (reduce impervious surface, energy and water use)
• Numerous new and existing trees shading the building
• Educational/interpretative opportunities on the site

- Landscaped swales

- Native landscape/plant identification

- Functional/artistic use of rainwater (flow forms, etc.)

- Art/sculptures

- Measure/display rainwater runoff

Water Efficiency

1. WE Cr 1.1       High efficiency irrigation system have been programmed
2. WE Cr 2.0       Rainwater/gray water for flushing

Waterless urinals

Perhaps this credit has low LCC value but high educational value

WE Cr 3.1       Possible point with measures listed in WE CR 2.0

Energy and Atmosphere

1. EA Cr 1.0        The building as designed has very low heating/cooling loads

Under floor air distribution system

•                         Daylighting with tuned high performance glazing
•                         Hybrid natural ventilation (operable windows w/ fan exhaust)
•                         Lighting controls
•                         Potential night flushing of interior building mass
•                         Exterior Shading

                                    - Overhangs

                                    - Deep recessed windows

                                    - Trees and adjacent buildings (need site shading study)

1. EA Cr 2.0        Additional funding would be needed for renewable energy

                        This may be a better fit for the upcoming Science Building project

1. EA Cr 3.0        Need to define scope for commissioning agent
   1. EA Cr 4.0        Need to submit an interpretation question to the USGBC for connection to central plant chiller. Technically no HCFC’s in building.
   2. EA Cr 5.0        Integrate M&V with building controls system. Assign responsibility for producing M&V plan
   3. EA Cr 6.0        Explore green power options available after utility restructuring in 2002 (green power will be available after restructuring)

Materials and Resources

Prerequisite:      Verify required recycling collection area on ground floor

1. MR Cr 2.0       Set a goal of 90% construction waste diversion. Deconstruction of existing buildings

Green Building Services                          2                                  July 18, 2001

1. MR Cr 3.0       Potential for 5% salvaged/reused building materials

                                    - Salvaged paving cobbles

                                    - Reused access floor

                                    - Salvaged wood trim

                                    - What materials are available from deconstruction (glulams, etc.)

- Wood from Cherry trees on site

1. MR Cr 4.0       Potential for 50% recycled content materials

                                    - Fly Ash                      - Ceramic tile                - Particle board

                                    - Compost                    - Access floor               - Brick

                                    - Steel                          - Toilet partitions                                                                                  - Carpet              - Gyp. board

1. MR Cr 5.0       Potential local/regional manufactured and extracted materials    

                                    - CMU/brick                - Casework/millwork

                                    - Doors                        - Window blinds

                                    - Windows                   - Furniture                   

                                    - Compost/plants          - Concrete

1. MR Cr 7.0       Opportunities for certified wood products                    

-         Ash is primary wood species

-         Millwork, casework and doors

Indoor Environmental Quality

IEQ Cr 4.0       Research available composite wood products

1. IEQ Cr 6.1       Classroom lighting controls to meet intent of credit
2. IEQ Cr 6.2       Need credit interpretation for individual control in classrooms
   1. IEQ Cr 7.1       In winter, humidity drops too low in Dec. & Jan. Consider credit interpretation
   2. IEQ Cr 8.0       Tuned glazing and shading to avoid glare
   Innovation and Design Process

ID Cr 1            Building is an educational tool demonstrating environmental concepts

ID Cr 2            Significantly exceed construction waste management requirement of 75%

Actions/Next Steps

 

q     City of Portland G-Rated funding application

q     Align commissioning agent and define scope

q     Begin materials and products research

q     Tie in 1% for art with “green” goals

q     Plan for student involvement - identify tasks for students (interpretive programming, etc.)

Feedback on Process

What would you change?	What worked well?
- Needed broader involvement of      various L & C representatives        - Provide list of usual material and      strategy choices to work from      during discussion	- Well organized       - Optimism at involvement/engagement       of “real world” team members       - Scorecard is improved over old version
