Understanding Innovation in Design & Exemplary Performance Credits in LEED
Energy and Atmosphere 6 – Green Power
Intent:
Encourage development and use of grid-source renewable energy technologies for NET ZERO pollution basis.
Implementation:
TYPES OF RENEWABLE ENERGY (as defined by the CRS – Center for Resource Solutions):
Solar
Photo-voltaic
Wind
Geothermal heating and electric
Biomass
Bio-gas
Low-Impact Hydro Electric
determine BASELINE electricity use from:
consumption based on EA1 – Optimize Energy Performance
use DOE (Department of Energy) CBECS (Commercial Building Energy Consumption Survey)
CASE 1: in [...]
Materials and Resources 7 – Certified Wood
Intent:
Encourage forest management program.
Implementation:
Use minimum of 50% of wood materials and products certified in accordance with FSC (Forest Stewardship Council) Principles and Criteria for wood building components:
framing
flooring and sub-flooring
wood doors
etc.
Based on Cost of FSC wood products compared to total wood material cost.
Exclude MEP and elevator equipment
Furniture is okay to be used in this calculation
Contractor [...]
Materials and Resources 6 – Rapidly Renewable Materials
Intent:
Reduce use of “long cycle” and finite raw materials.
Implementation:
Use rapidly renewable materials and products for 2.5% of total value of all building materials and products used (based on cost)
harvested within a 10-year cycle or shorter
consider:
bamboo flooring
wool
cotton insulation
cork flooring
linoleum flooring
wheat board cabinets
straw board
agrifiber
Code:
none
Submittal Phase:
construction
Extra Credit:
use 5% instead of 2.5% for an extra point.

Achieve direct line of site to outdoor for occupants in 90% of all regularly occupied areas
glazing between 2′-6″ & 7′-6″
Plan View:
area within sight lines drawing from perimeter vision glazing
Section View:
direct line of sight can [...]
Indoor Environmental Air Quality 8.1 – Daylighting and Views – Daylight 75% of Spaces
Intent:
Provide connection between indoor and outdoor spaces through introduction of daylight and views into regularly occupied areas of the building.
Implementation:
OPTION 1 – GLAZING FACTOR CALCULATION
achieve min. 2% glazing factor in minimum of 75% of regularly occupied areas.
OPTION 2 – DAYLIGHT SIMULATION MODEL
through computer simulation, demonstrate min. daylight illumination level of 25 footcandles in min. of [...]
Materials and Resources 4.2 – Recycled Content – 20% Total Construction Material from Recycled Items (post consumer + 1/2 pre-consumer)
Same as credit MR 4.1, except for percentage of total construction material from recycled items (10% in Materials and Resources 4.1)
20% of Total Construction Material from Recycled Items (post consumer + 1/2 pre-consumer)
Intention:
