How Does Draper Impact LEED NC v 3

    Draper’s Impact on LEED 2009

    ?By Clint Childress (LEED-AP)

    Green Buildings Coordinator and Window Shades Product Specialist, Draper, Inc.

    Below is a list of credits toward which Draper can help contribute or provide needed information. LEED Reference Guide for Green Building Design and Construction, 2009 edition, is the source used for the information in this document.

Sustainable Sites

Credit 8, Light Pollution Reduction:

    This credit has two parts, interior lighting control and exterior lighting control. Both parts must be satisfied to earn this credit. The interior lighting portion of this credit has two compliance options to choose from. Draper’s motorized shades, used in conjunction with Draper controls,

    can meet the option 2 compliance method for the interior lighting portion of the credit:

    “All exterior openings, such as windows, must have shielding that can be automatically

    controlled and programmed to close from 11:00 p.m. to 5:00 a.m. Shielding options

    include automatic shades that have less than 10% transmittance. An example is a timer-1controlled automated rolling shade with the appropriate light transmittance.”

Credit 9, Tenant Design and Construction Guidelines:

    This credit is only for LEED Core & Shell (CS). The intent of this credit is to educate tenants on sustainable design for their tenant improvement build-out. One of the LEED 2009 credits to be addressed is Daylighting and Views. Window shades are an excellent choice to control glare when pursuing a daylighting strategy.

    “So that tenants can optimize daylighting, a LEED for Core & Shell commercial office

    building design should consider floor-to-ceiling heights, the bay size, the type of glazing,

    and the depth of occupied spaces. Daylight shelves and glare control devices should also 2be considered.

Credit 9, Site Master Plan

    This credit is only for LEED SCHOOLS. The credit requires that 4 out of 7 credits be achieved. One of the credits is SS Credit 8: Light Pollution Reduction. The effects of Draper window shades on this credit are described above.

Energy & Atmosphere

Prerequisite 1- Fundamental Commissioning of Building Energy

    Systems:

    To achieve LEED certification all prerequisites must be satisfied. This prerequisite requires a commissioning authority (CxA) to take a number of fundamental commissioning steps. Commissioning activities must be completed for lighting and daylighting controls. Draper can provide information about our window shade controls.

    “Commissioning process activities must be completed for the following energy-related

    systems, at a minimum (if they are installed as part of the core and shell 3project)…lighting and daylighting controls…”

    Sustainable Sites Credit 8: Light Pollution Reduction is a related credit (see page 1).

Prerequisite 2- Minimum Energy Performance

    To achieve LEED certification all prerequisites must be satisfied. This prerequisite requires a 10% improvement (55% for existing buildings) compared with the baseline building

    performance rating. Draper motorized shades, operating based on the sun’s movement through

    automated controls such as SolarFlex and Draper Digital Network, will increase energy

    efficiency. Motorized shades should be included in the energy model.

Credit 1- Optimize Energy Performance

    This credit is worth up 19 points. The minimum energy cost savings percentage is 12% for new buildings and 8% for existing building renovations. Additional points (up to 19) can be awarded for greater percentage savings. Draper’s motorized shades, operating based on the sun’s

    movement through automated controls such as SolarFlex and Draper Digital Network, will increase energy efficiency. Motorized window shades should be included in the energy model.

    “Manually controlled interior shading devices such as blinds and curtains should not be 4modeled. Automatically controlled interior shading devices can be modeled…”

Credit 3- Enhanced Commissioning

    There are 12 steps involved in the enhanced commissioning process. By providing information and documentation, Draper can assist with Steps 9 and 10. Step 9 specifies that a systems manual be developed for all commissioned systems. Daylighting controls were a requirement Prerequisite 1, Fundamental Commissioning. Step 10 requires training on commissioned systems for operating personnel and building occupants. Related credits include: Sustainable Sites Credit 8: Light Pollution Reduction; and Energy and Atmosphere Credit 1: Optimize Energy Performance.

Materials & Resources

Credit 3- Materials Reuse

    This credit considers the reuse of materials on the project. This credit only considers products in CSI divisions 3-10. Draper projection screens are in Division 11. Draper gymnasium equipment is in Division 11. Draper window shades are in Division 12, which can possibly be counted in this credit. It is possible that Draper window shades salvaged for reuse could contribute towards this credit.

    “Exclude furniture and furnishing (CSI Division 12 components) unless they are 5included consistently across MR credits 3-7.”

Credit 4- Recycled Content

    This credit considers the recycled content of materials on the project. This credit only considers products in CSI divisions 3-10. Draper projection screens are in division 11. Draper gymnasium equipment is in Division 11. Draper window shades are in Division 12 which can possibly be counted in this credit. Draper uses components with recycled content. It is possible that Draper window shades could contribute to this credit. Please contact Draper for recycled content information.

    “Exclude furniture and furnishing (CSI Division 12 components) unless they are 6included consistently across MR credits 3-7.”

Credit 5-Regional Materials

    This credit considers products which have been extracted, harvested and manufactured within 500 miles of the project. This credit only considers products in CSI divisions 3-10. Draper projection screens are in division 11. Draper gymnasium equipment is in Division 11. Draper window shades are in Division 12 which can possibly be counted in this credit.

    “Exclude furniture and furnishing (CSI Division 12 components) unless they are 7included consistently across MR credits 3-7.”

Indoor Environmental Quality

Credit 8.1- Daylight and Views-Daylight

    The intent of this credit is to provide building occupants with a connection between indoor spaces and the outdoors through the introduction of daylight and views. Go to Draper’s Web
