LEED v3 Certification Guideline

The Leadership in Energy and Environmental Design (LEED) Green Building Rating Systemtm is a voluntary, evolving, consensus-based national standard for developing high-performance, sustainable buildings using a comprehensive, point-based system. As the adoption of sustainable building practices increases, it becomes increasingly critical that architects have the most up-to-date information on tools and performance criteria during the development stage.

 

We are dedicated to developing products, systems, and services that help comply with LEED standards and promote integrated, whole-building design practices. See how you can design sustainable buildings with Kawneer products using the charts below.

1. Optimize Energy Performance
Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impact associated with excessive energy use.
1-19
Select one of the three compliance path options below.
(1-19)
OPTION 1: Whole Building Energy Simulation
Demonstrate a percentage improvement in the proposed building performance rating compared to the baseline building performance rating per ASHRAE/IESNA Standard 90.1-2007 (with errata but without addenda) by a whole building project simulation using the Building Performance Rating Method in Appendix G of the Standard.
(1)
OPTION 2: Prescriptive Compliance Path
Comply with the prescriptive measures of the ASHRAE Advanced Energy Design Guide appropriate to the project scope. Project teams must fully comply with all applicable criteria as established in the Advanced Energy Design Guide for the climate zone in which the building is located.
(1-3)
OPTION 3: Prescriptive Compliance Path: Advanced BuildingsTM Core PerformanceTM Guide
Comply with the prescriptive measures identified in the Advanced BuildingsTM Core PerformanceTM Guide developed by the New Buildings Institute.
2. On-site Renewable Energy
Encourage and recognize increasing levels of self-supply through renewable technologies to reduce environmental impact associated with fossil fuel energy use.
1-7
Use on-site renewable energy systems to offset building energy cost. Calculate project performance by expressing the energy produced by renewable systems as a percentage of the building annual energy cost and using the table below to determine the number of points possible:
RENEWABLE ENERGY POINT(S)

MATERIALS & RESOURCES
Potential Points
LEED Requirements
Kawneer Products + Services
4.1 Recycled Content: 10%
Increase demand for building products that incorporate recycled content materials, therefore reducing the impact resulting from extraction and processing of virgin materials.
1
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% (based on cost) of the total value of the materials in the project.
4.2 Recycled Content: 20%
Increase demand for building products that incorporate recycled content materials, therefore reducing the impact resulting from extraction and processing of virgin materials.
(4.1) + 1
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 20% (based on cost) of the total value of the materials in the project.
5.1 Regional Materials: 10% Extracted, Processed and Manufactured Regionally
Increase demand for building materials products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impact resulting from transportation.
1
Use building materials or products that have been extracted, harvested or recovered, as well as manufactured within 500 miles of the project site for a minimum of 10% (based on cost) of the total materials value. If only a fraction of a product or material is extracted / harvested / recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.
5.2 Regional Materials: 20% Extracted, Processed and Manufactured Regionally
Increase demand for building materials products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impact resulting from transportation.
(5.1) + 1
Use building materials or products that have been extracted, harvested or recovered, as well as manufactured within 500 miles of the project site for a minimum of 10% (based on cost) of the total materials value. If only a fraction of a product or material is extracted / harvested / recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.

2 Increased Ventilation
Provide additional outdoor air ventilation to improve indoor air quality for improved occupant comfort, well-being and productivity.
1
For mechanically ventilated spaces, increase breathing zone outdoor air ventilation rates to all occupied spaces by at least 30% above the minimum rates required by ASHRAE Standard 62.1-2007 as determined by EQ Prerequisite 1. For naturally ventilated spaces, design natural ventilation systems for occupied spaces to meet the recommendations set forth in the Carbon Trust "Good Practice Guide 237" [1998].
6.2 Controllability of Systems: Thermal Comfort
Provide a high level of thermal comfort system control by individual occupants or specific groups in multi-occupant spaces to promote the productivity, comfort and well-being of building occupants.
1
Provide individual comfort controls for 50% (minimum) of the building occupants to enable adjustments to suit individual task needs and preferences. In certain areas, operable windows can be used in lieu of comfort controls. The areas of operable window must meet the requirements of ASHRAE 62.1-2007 paragraph 5.1 Natural Ventilation.
8.1 Daylight and Views (Daylight 75% of Spaces)
Provide for the building occupants with a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
1
OPTION 1: Simulation
Demonstrate through computer simulations that 75% or more of all regularly occupied spaces achieve defined daylight illuminance levels of a minimum of 25fc and a maximum of 500fc.
 
OPTION 2: Prescriptive
Use a combination of side-lighting and/or top-lighting to achieve a total Daylighting Zone that is at least 75% (1 point) of all the regularly occupied spaces.
 
OPTION 3
Any of the above calculation methods may be combined to document the minimum daylight illumination in at least 75% of all regularly occupied spaces. The different methods used in each space must be clearly recorded on all building plans.
 
OPTION 4: Measurement
Demonstrate, through records of indoor light measurements, that a minimum daylight illumination level of 25 foot-candles has been achieved in at least 75% of all regularly occupied areas.
8.2 Daylight and Views (Views 90% of Spaces)
Provide for the building occupants with a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
1
Achieve direct line of sight to the outdoor environment via vision glazing between 2'6" and 7'6" above finish floor for building occupants in 90% of all regularly occupied areas.
