U.S. Energy Code Status ASHRAE 90.1

California Title 24 LEED EPAct 2005

ASHRAE 90.1 Overview

To promote the use of energy-efficient lighting in commercial and high-rise residential buildings, the energy code requires:  Manual or automatic controls (

e.g. Occupancy Sensors, Panels

) or switches that allow occupants to dim lights and turn them on or off when appropriate. (e.g. Occupancy Sensors)  Total connected loads for indoor lighting systems that do not exceed power allowances for the building ( uses power density limits in W/sf).  Energy-efficient exterior lighting.

Section 9 – Lighting 9.4 Mandatory Provisions 9.4.1 Lighting Control 9.4.1.1

Automatic Lighting Shutoff

Interior lighting in

buildings

larger than 5000 ft 2 shall be controlled with and shut off

building automatic control device

lighting in all spaces. This to

automatic control device

shall function on either: a) A scheduled basis using a time-of-day operated control device that turns lighting off at specific programmed times – or b) An

occupant sensor

that shall turn lighting off within 30 minutes of an occupant leaving a space – or c) A signal from another control or alarm system that indicates the area is unoccupied,

9.4.1.2

Space Control

Each space enclosed by ceiling-height partitions shall have at least one control device for independently controlling the general lighting and shall be readily accessible and located so the occupant can see the controlled lighting. a) A control device shall be installed that automatically turns off the lighting within 30 minutes of all occupants leaving a space, except spaces with multi-scene control, in: 1) Classrooms, (not including shop classrooms, laboratory classrooms and preschool through 12th grade classrooms) 2) Conference/meeting rooms, 3) Employee lunch and break rooms. b) For all other spaces, each control shall be activated either manually by an occupant or automatically by sensing an occupant. Each control device shall control no more than 2,500 sq.ft. in spaces smaller than 10,000 sq.ft. and a maximum of 10,000 sq.ft. in spaces over 10,000 sq.ft. and be capable of overriding the automatic lighting shutoff for no more than 4 hours.

California Title 24

 Energy Code for new buildings in California that greatly influences other codes such as ASHRAE-90.1

 Section 119 – Mandatory Requirements for Lighting Control Devices – Sensor Switch products are fully compliant w/ Title 24  Section 131 – Mandatory Requirements for Lighting Systems & Equipment – Similar to ASHRAE 90.1 with added requirements for Multi-Level and Daylighting Control

Leadership in Energy and Environmental Design (LEED)

     U.S. Green Building Council administered rating system that provides a national standard for what constitutes a green building.

Points in different categories are earned for meeting certain criteria LEED-NC is for New Construction & Major Renovations LEED-CI is for Commercial Interiors

Sensor Switch products may contribute to obtaining up to 22 points in 5 of 6 LEED-NC categories and 14.5 points in 5-6 LEED-CI categories

EPAct 2005

 The Energy Policy Act of 2005 created the Energy Efficient Commercial Buildings Deduction  Allows building owners to deduct the entire cost of an interior lighting upgrade in the year the equipment is placed in service, subject to a cap.

 A maximum of $0.60/sq.ft. is available if: – – – Bi-Level Switching is installed (except for exceptions) Lighting controls meet ASHRAE 90.1-2001 Reduce lighting power density by at least 25-40% of levels prescribed by ASHRAE 90.1-2001

Bi-Level Switching and EPAct

Bi-level switching is defined as manual or automatic control (

e.g. occupancy sensors

) that provides two levels of lighting power in a space (not including off).

Bi-level switching strategies include  Split-ballasting to allow separate control of 50% of lamps or fixtures      Bi-level ballasts Multiple-ballasts within one fixture Dimming ballasts Manual controls or dimmers Photosensors
