Points Scale
LEED Requirements: 2 Increased Ventilation
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]
LEED Requirements: 6.2 Controllability of Systems: Thermal Comfort
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.
LEED Requirements: 8.1 Daylight and Views (Daylight 75% of Spaces)
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.
LEED Requirements: 8.2 Daylight and Views (Views 90% of Spaces)
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.
Thermal, architectural grade operable windows and 512 Ventrow ISOLOCK® Ventilator
To maintain aesthetic appeal without sacrificing thermal performance, Kawneer offers a wide range of thermal, architectural grade windows that can help leverage points in the Energy & Atmosphere category. Kawneer's operable windows can earn potential points in the Indoor Environmental Quality Category by providing controllable natural ventilation. The thermal 512 Ventrow, a modular insert ventilator, adds natural, concealed air circulation in fixed frames.
1600 SunShade®
Designed to shade interiors and optimize energy performance by reducing solar heat gain, 1600 SunShade® works with Kawneer products to allow greater use of glazing while reducing demand on the HVAC. These properties can help qualify for LEED points in the Energy & Atmosphere category.

InLighten® Light Shelf
InLighten® Light Shelf is designed to integrate with 1600 curtain wall systems to reflect natural light deeper into occupied spaces. InLighten® directs available natural light to interior spaces and can help qualify for points in the Indoor Environmental Quality category. In addition, light shelves have been proven to reduce requirements for artificial perimeter lighting, thereby conserving electrical energy costs.

1600 Sloped Glazing & 2000 Skylight
Opening the center of a building with overhead pyramid skylights is one of the fastest and easiest ways to provide natural lighting to an interior space. The insulating thermal break is placed to the exterior of the plane of glass to minimize heat loss and condensation. These systems can qualify for points in the Indoor Environmental Quality category of the LEED certification process.
High–performance Thermal Products
High–performance thermal systems are designed to provide optimum thermal performance leading to greater energy conservation. Kawneer systems offer infills from 1"IG (Insulating Glass) to 2" maximum performance triple-glazed units. Thermally-broken products such as 7500 Wall®, 5500 and AA®900 ISOWEB® Windows, AA®3200 ISOWEB® Sliding Door, and 1600 Wall System® 3 and 4 maximize thermal performance by reducing thermal transmittance. These systems can help qualify for LEED points in the Energy & Atmosphere category.
Identify Potential LEED Credits
Kawneer's LEED Planning Tool lists and references various LEED requirements. It shows how many potential points each requirement is worth and recommends products that can help to earn these points. The tool can be used to estimate LEED points and track progress toward certification.
