LEED Process

Defining Sustainability : Meeting the needs of the present without compromising the needs of the future.

How does this relate to the construction industry? We, in the construction industry by the nature of our business utilize a

tremendous amount of resources and energy in order to build structures.

Our challenge is to build structures that work with the environment, minimize energy and resource use and actively pursue building spaces with healthy indoor environments.

This is what most people think of when they hear the term ‘green building’

There is a perception that green is brown and doesn’t incorporate beautiful design

And somehow these same people think THIS costs 20% more

Perception

But this is the reality of green design in the marketplace

Proving green interiors do not have to sacrifice on amenities

This is the REI Portland store proving green design can be functional, urban and modern

Reality

There is no simple answer to this question as it depends on the job. Some jobs can reach a Certified level at very little or no cost above conventional construction practices. Jobs seeking Gold or Platinum levels of Certification typically require expenditures to achieve these levels. It is important to understand that these expenditures are adding quality and should be looked upon as quality enhancements to the project.

Owners that are pursuing these ratings are doing so because they are getting a higher quality project that is expected to more than pay for the increases in 1st costs over the life of the facility. (This is one of the barriers that tend to thwart Spec office builders from pursuing Green Buildings.)

These 1st costs are offset by the following: Decrease in energy costs due to increased energy efficiencies of the

building. Decreased Maintenance and operating costs due to better HVAC

Systems and Exterior Envelope Systems. Increases in employee productivity. Less absenteeism, sickness, insurance claims

Buildings are LEED Certified People are LEED Accredited Materials are neither

LEED is an overall design concept, not depending on individual materials

LEED Process

Construction and Demo activities contribute about 40% of total solid waste stream in the United States

Activities can be described as the process of extraction, processing, transporting and the steps used to process them

Intent – Divert construction and demolition debris from disposal in landfills. Redirect recyclable materials back to the manufacturing process. Redirect reusable materials to appropriate sites

Requirement – Recycle or salvage at least 50% (or 75%) of non-hazardous debris. Develop and implement a construction management plan that identifies materials and methods of sorting

Exclude excavation and landscaping debris. Exclude hazardous materials Reclaimed or crushed concrete, asphalt, or masonry re-used on-site may be

included in calculations.

Note – Credits 2.1 & 2.2 are cumulative (2 points possible)

Submittal Documentation – Construction Submittal Calculations – By Weight or Volume; must be consistent

throughout project duration Default Materials Cost: Apply 45% of the projects cost to establish a

default total of materials cost for the project Other Material Cost Sources: Contact the Turner Estimating

Department or Subcontractors

Intent – Reuse building materials and products to reduce waste and to reduce demand for virgin materials, thereby reducing the impacts of extracting and processing virgin resources

Requirement – Use salvaged, refurbished or reused materials such that the sum of these materials constitutes at least 5% (MR3.1) or 10% (MR 3.2), based on cost, of the total value of materials on the project

Include only materials permanently installed in project for calculation Div. 2 – 10 only; exclude mechanical, electrical, plumbing components,

specialty items, and equipment Furniture may be included if it is included consistently in MR Credits 3 – 7

Referenced Standard None

Calculations List cost of reused materials (actual cost or replacement value) Percent Reuse = Cost of Reuse Materials / Total Materials Cost (div. 2 – 10 only) Total Materials Cost for project can be calculated in 2 ways:

– Multiply total construction cost (div. 2 – 10) x 0.45 Or

– Add up actual materials cost (div. 2 – 10) Exclude furniture and furnishings (div 12), unless included consistently for MR Credits

2 – 7 Submittals

Provide percent reuse calculations Provide total project cost (div. 2 – 10) Provide tabulation of each salvaged / reused material Provide a narrative of reuse strategy

Intent Increase demand for building products that incorporate recycled content materials

thereby reducing impacts resulting from extraction and processing virgin materials Requirements

Use materials with recycled content such that the sum of post consumber plus ½ of sum of pre-consumer material cost is at least 10% (MR 3.1) or 20% (MR 3.2) of the total value of materials on the project

– Include only materials permanently installed in project for calculation– Div 2 – 10 only; exclude mechanical, electrical, plumbing components, specialty items, and

equipment– Furniture may be included if it is included consistently in MR credits 3 – 7

Referenced Standard Recycled content shall be defined in accordance with ISO 14021 – Environmental

labels and declarations – Self-declared environmental claims (Type II environmental labeling

Use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (20% for Credit 4.2) based on cost of the total value of materials on the project.”

Definitions Post Consumer: waste material generated by end users that can no longer be

used for its intended purpose. Included discarded products. Pre-Consumer: material diverted from the waste stream during the

manufacturing process. Excludes material that can be reclaimed in the same process that generated it.

Post Industrial: Previous name for Pre-Consumer

Calculations Recycled content value = (% post consumer recycled content x cost) + 0.5 x (pre-

consumer recycled content x cost) Percent Recycled Content = Recycled content value / Total material cost

– Exclude furniture and furnishings (div. 12), unless included consistently for MR Credits 3 – 7 Total Materials Cost for project can be calculated in 2 ways:

– Multiple total construction cost (div. 2 – 10) x 0.45Or

– Add up actual material cost (div. 2 – 10) Submittals

Provide percent reuse calculations Provide total project cost (div 2 – 10) Provide tabulation of each salvaged / reused material Provide a narrative of reuse strategy

Intent – Increase demand for building products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing environmental impacts resulting from transportation

Requirement – Use materials with recycled content that have been extracted, harvested or recovered as well as manufactured within 500 miles of the project site for a minimum 10% (MR 5.1) or 20% (MR 5.2) by cost

If only a fraction is regional, use % by weight of that portion Div. 2 – 10 only; exclude mechanical, electrical, plumbing components,

specialty items, and equipment Furniture may be included if it is included consistently in MR credits 3 – 7

Referenced Standard – None

Calculations List cost of products extracted/harvested/recovered and manufactured within

500 miles of project Indicate name of manufacturer, product cost (to owner) and distance from site

for each raw material in each product Total Materials Cost for project can be calculated in 2 ways:



Complete materials calculation table on template (see table 2 pg. 275) Provide total project cost (div 2 – 10) Optional: Provide a narrative of any special circumstances

Definitions Regionally-extracted materials must have their source as a raw

material from within a 500-mile radius of the project site Regionally-manufactured materials must be assembled as a finished

product within a 500-mile radius of the project site; assembly does not include on-site assembly, erection or installation of finished components

Environmental Considerations Local/regional materials

– Support local economy– Reduce transportation costs and environmental impacts– Retain money paid for materials within region

Materials cost calculations for project includes only Div. 2 – 10: Exclude mechanical, electrical and plumbing components Exclude equipment and appliances Exclude elevators Exclude furniture and furnishings (Div 12), unless included consistently for

MR Credits 3 – 7

Reused and Salvaged Materials Re-used and salvaged materials that satisfy requirements of MR

Credits 3.1 and 3.2 may also contribute to MR Credits 5.1 and 5.2. Point of extraction – Location from which they were salvaged. Point of manufacture – Location of salvaged goods vendor Materials re-used and salvaged from on-site automatically qualify as

‘regional materials’

Material partially manufactured or extracted locally To figure the value of regional materials use only that portion and

associated cost manufactured or extracted within 500 miles of the project site

Material wholly-locally manufactured but partially-locally extracted To figure the value of regional materials in an assembly, use the

percent by weight of regional materials in the assembly components
