LEED Certification

Klein interior glass sliding doors can help earn points in several LEED categories.

Energy and Atmosphere (to promote better building energy performance though innovative strategies)

Optimize Energy Performance (EA 1.0) The use of glass minimizes the need for conventional lighting, resulting in significant energy savings. Points earned for reducing lighting power density below the standard:
15% => 1 point
20%=> 2 points
25% => 3 points
30%=> 4 points
35% => 5 points

Materials & Resources (to encourage using sustainable building materials and reducing waste)


Building reuse (MR1.2): glass walls can be moved to renovate an existing space, reducing demolition in the old space and requiring fewer resources in the new space. Designers must maintain at least 40 or 60 percent by area of the existing non-shell, nonstructural components (e.g., walls, flooring and ceiling systems). The minimum percentage interior component reuse for each point threshold:
40% => 1 point
60%=> 2 points

Construction Waste Management (MR 2.1): The use of glass versus drywall construction eliminates the waste as the glass is manufactured to fit perfectly in the opening while the drywall comes with standard dimensions that need to be cut on site with some materials left over. The minimum percentage debris left to be recycled or salvaged for each point threshold:
50% => 1 point
75%=> 2 points

Regional Materials (MR 5.1, 5.2):  To increase demand for materials and products extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing transportation impact. The requirements are to use a minimum of 20 percent of the combined value of construction and Division 12 (furniture) materials and products manufactured regionally within a 500 mile (800 kilometer) total travel distance from the project site.

2 points=> The selection of a local glass manufacturer matches the 500-mile requirement for two LEED points under this credit.
Indoor Environmental Quality (to promote better indoor air quality and access to daylight and views)
Construction Management Plan (IEQ 3.1 and 3.2): Glass walls are manufactured off site to fit the space, eliminating jobsite waste, dust, and required clean up.

Low Emitting materials: Adhesives and Sealants (IEQ 4.1) All adhesives and sealants used in the building interior, (i.e., inside the weatherproofing system and applied on-site) must comply with the following requirements as applicable to the project scope: the South Coast Air Quality Management District (SCAQMD) Rule #1168 and no emittance of VOCs. (1 point)

Daylight and Views (IEQ 8.1 and 8.2): To provide occupants with a connection between indoor and outdoor spaces, introduction of daylight and views into regularly occupied areas of the tenant space. Full glass partitions allow daylight to pass into and around interior areas and maintain a line of sight to the outdoors. 2 points can be earned according to the degree of occupancy:
75% regularly occupied space => 1 point
90% regularly occupied space => 2 points

Innovation and Design Process (To address sustainable building expertise and design measures not covered under the five major LEED categories.)
Innovation in Design (ID1):  The use of sliding glass doors allows reducing the space needed to access a room, which allows the design of smaller spaces. The frameless sliding systems are also easy to install or dismount, providing quick installation.
