PUTTING A STOP TO ENERGY WASTE®

energy code compliance

over the past ten years, most

jurisdictions have adopted reference

standards such as anSi/aSHrae/ieSna*

90.1 (aSHrae) and international energy

conservation code (iecc). This means

that design professionals, building

owners and operators, and facility

managers need up to date tools to ensure

code compliance.

WattStopper’s codeSmart energy code

initiative provides information you can

trust:

• up to date code requirements for all

major codes

• design guidance in developing code-

compliant projects

• technical expertise in implementing

code-compliant projects

With mandatory energy code requirements

on the state, regional, and local levels,

virtually every facility faces

lighting control requirements.

With federal tax incentives

available under EPAct 2005,

understanding, meeting, and

exceeding code requirements represents

a business opportunity as well (see pg. 30

as energy codes become more rigorous, they are including specific provisions for different types of interior spaces. project teams need a range of control solutions capable of complying with these requirements, as well as the flexibility to easily go beyond code requirements to help achieve additional energy management or sustainability goals.

WattStopper's Digital Lighting Management (DLM) provides the sophisticated and robust control capabilities needed to achieve both the mandatory code requirements as well as these advanced goals.

Automatic shutoff of general lighting While different standards vary in exceptions and implementation, the core requirement is automated lighting shutoff. Acceptable methods for complying with automated shutoff requirements are time-scheduled shutoff (this page) occupancy-based shutoff (facing page) or a signal from another control system (e.g. baS). Time scheduled shutoffScheduling lighting to turn on and off based on normal business hours provides a convenient way of automating general facility lighting. using a segment manager to schedule lighting shutoff enables code compliance in many codes and in many spaces (see code compliance guide, pages 6-15 for more details). Local override or space control switches enable local lighting operation regardless of scheduled status. Using DLM products ensures code compliance and the ability to implement options such as networked control, remote administration, real-time monitoring, even demand response strategies.

Occupancy based shutoffFor spaces that follow less predictable schedules or are intermittently occupied, occupancy sensors provide reliable automated shutoff. When an area becomes unoccupied, the sensors signal lighting to turn off.

all three major codes include provisions for reducing light levels. achieving this can be done by:• controlling all lamps or luminaires• dual switching of alternate rows, luminaires, or lamps• switching independent lamps within a luminaire• switching each luminaire

One of the easiest methods to achieve this is by using multi-button wall switches (two buttons or more) in conjunction with occupancy sensors. The sensors provide the automated shutoff and the switches provide the ability to reduce light levels when necessary.

All three major codes now require some form of daylighting control. While each code sets forth specific provisions, all share the approach of requiring independent control of some portion of the lighting in a daylit zone.

Using DLM daylighting controls gives users flexibility to implement either switching or dimming control depending on the configuration of the space and other design objectives. in addition, users can easily integrate the daylighting control with other lighting and energy management controls for maximizing building energy performance.

Mandatory in ASHRAE 90.1-2010

New mandates require automated shutoff of receptacles in specific space types, including computer classrooms, private offices, and open offices. These provisions are designed to control proliferating plug load energy consumption, now estimated as accounting for between 15-20% of a building’s total electrical energy consumption.

dlm plug load control products allow users to integrate plug load control with lighting control, by using the control device (either occupancy sensor or control panel) to also control identified receptacles. Additional options include real-time consumption monitoring, for identifying abuse or usage patterns or implementing demand response strategies.

Exterior lighting consumes a significant amount of energy.

parking lot and garage lighting alone operate more than 314 billion

hours each year, accounting for more than 50 TWh of electrical

energy use annually. To provide greater energy efficiency while

maintaining robust safety and security levels, each of the major

energy codes includes provisions for control of exterior lighting.

In addition to these existing requirements, the 2010 revision of

ASHRAE 90.1 adds specific requirements for parking garage

lighting.

WattStopper offers innovative solutions for these challenging

environments, including rugged

motion sensors specifically

engineered for LED outdoor fixtures

as well as cost-effective control

panels for scheduled control.

Each code has different specifics, but, in general, mandate that exterior lighting be automatically shut off as well as controlled by occupancy sensors, photocell, astronomical time switch or some combination of these devices.

Photocell controloperating by measuring available daylight, photocells turn lighting off when daylight becomes sufficient at dawn, and turn lighting on when daylight levels diminish at dusk.

New code provisions in ASHRAE 90.1-2010 mandate multi-level, occupancy-based control of parking garage lighting. In addition, separate daylight-responsive control is required for daylight transition zones.

Products: • FSP-211• FSIR-100

Best applications: • parking garages• parking lots• gas stations

Under the Energy Policy Act of 2005 (EPAct), mandatory code compliance provides a foundation for an even greater opportunity. EPAct 2005 enables commercial building owners to invest in energy efficiency, with a Commercial Building Tax Deduction (CBTD) for capital investments in energy efficiency equipment, including lighting controls.

Lighting Tax Deduction Provisions Lighting system projects may qualify for a partial deduction of up to $0.60/ft2. To do so, projects must satisfy the following requirements set forth in the interim rules:1. Reduce lighting power density (LPD) by 25-40% beyond the minimum

requirements outlined in ASHRAE 90.1-2001 (warehouse spaces must reduce LPD by 50%)

A pro-rated deduction is allowed for projects that reduce LPD between 25 and 40% as illustrated in the table.
