Columbia Skylights Statement for LEED™

New Construction (NC) Version 3.0 Credit Documentation

The Leadership in Energy and Environmental Design (LEED™) Green Building Rating System® promotes the adoption of sustain-able green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria.

LEED™ is a third-party certification program and an internationally accepted benchmark for the design, construction and opera-tion of high performance green buildings. It provides building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. LEED™ promotes a whole-building approach to sustainability by recognizing performance in six key areas of human and environmental health:

1. Sustainable site development 2. Water efficiency 3. Energy efficiency 4. Materials selection 5. Indoor environmental quality 6. Innovation and design

Columbia Skylights may qualify your project for LEED™ points in the following categories:

LEED™ Credit SS 7.2 HEAT ISLAND EFFECT

Use roofing materials with a high Solar Reflective Index. Required SRI of > .78 or Vegetative coverage of > 50% or a combination of SRI and Vegetation.

To calculate the SRI click here

Columbia Skylights use state of the art LoE³ - 366® tech-nology to deliver 6 Energy Star® approved glass glazing options that help to mitigate the heat island effect through high solar reflectance and high thermal emittance. See page 5 for test results on Columbia’s glazing options.

When used in combination with vegetated roofing Columbia Skylights and Sun tubes can assist in providing additional energy savings.

LEED™ Credit SS 8.0 LIGHT POLLUTION REDUCTION

Reduce the light that trespasses from a building at night.

Columbia Skylight Blinds are available in three fabric op-tions: Privacy, Light Filtering and Blackout. Privacy, Light Filtering and Blackout blinds block 20%, 35% and 99% of light respectively. Every blind comes with aluminium side rails that prevents light leakage around the edges of the fab-ric. All Columbia Skylight Blinds can be configured to block light leakage from a building at night. See Table 3, page 6.

Energy ef� ciencyLEED™ Credit EA 1.0 OPTIMIZE ENERGY

PERFORMANCE

The most important LEED™ credit as reflected in the number of points available.

Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use.

For more information on how to gain this credit click here

Columbia Skylights are a source of natural light - reducing the need for artificial light/ energy consumption.

Venting Skylights are a source of natural air and ventilation. They can be used to reduce HVAC loads.

Columbia’s 6 glass glazing options are Energy Star® ap-proved. Each glazing option offers varying degrees of en-ergy efficiency. See page 5 for test results.

Sun Tubes used in applications where traditional windows or skylights cannot be installed lessen the need for artificial lighting solutions. Columbia’s residential sun tubes are En-ergy Star® approved in all 50 US States and in all 4 Cana-dian Climate zones. See Page 5 for test results.

Columbia Skylight Blinds can help to block up to 79% of heat gain. See Table 3 page 6.

Indoor Environmental QualityLEED™ Credit EQ 2.0 INCREASED VENTILATION

Increase ventilation rates to all occu-pied spaces by at least 30% above the minimum rates in ASHRAE 62.1-2007

Provide for the effective delivery of mixing of fresh air to support safety, comfort and well-being of building occupants.

Columbia’s Venting Skylights are a source of natural ventila-tion. Available in Manual and Electric venting kits, they pro-viding fresh air circulation without increasing HVAC load.

Venting Electric Skylight control allows for simultaneous control of multiple skylights using a wall switch or a remote.Columbia’s Deluxe and Elite electric kits include rain sen-sors that close the skylight at the first sign of moisture.

LEED™ Credit EQ 4.1 LOW EMITTING MATERIALS:

ADHESIVES AND SEALANTS

Reduce the quantity of indoor air contaminants that are odorous, irri-tating and/or harmful to the comfort and well-being of installers and oc-cupants.

The adhesives and sealants used in Columbia’s LoE³ -366® sealed glass units are emissions free and non hazardous resulting in no VOC emissions into the environment. 1

LEED™ Credit EQ 4.2 LOW EMITTING MATERIALS:

PAINTS AND COATINGS

Reduce the quantity of indoor air contaminants that are odorous, irri-tating and/or harmful to the comfort and well-being of installers and oc-cupants.

Columbia Skylights arrive on site pre assembled, painted and coated where applicable. The finished units do not con-tribute to air pollution and do not release dust or fibres. 1

LEED™ Credit EQ 6.1

CONTROLLABILITY OF SYTEMS

- LIGHTING

Provide a high percentage of lighting control for the buildings occupants to improve productivity and comfort.

Columbia Skylight Blinds provide light control for building occupants. 3 Blind options provide varying levels of light filtration. Blackout blinds block 99% of light. See Table 3 page 6.

Columbia’s 10” 13” and 21” sun tube models can be installed with a remote dimmer kit, giving the building oc-cupant control over the intensity of light entering a space.
