Lighting design – basic terms and concepts

Lamp A light source such as an incandescent, halogen, or fluorescent lamp. A lamp is sometimes called
a “light bulb” or simply a “bulb.”
                   • The label “low voltage” relates to safety, not to energy consumption or efficiency.

Incandescent       A metal filament glows hot to produce light.
                   • The label “full-spectrum” applies to all incandescent bulbs, and means nothing.

Halogen            A metal filament glows hot to produce light, and halogen gas in the lamp increases the
                   efficiency of the lamp and extends the life of the filament.

Fluorescent        Electrified gas glows to produce light.
                   • Compact fluorescent light bulbs best serve in residential applications.
                   • T8, T12: Linear fluorescent lamps are identified by T for tubular, and the number of
                       eighths of an inch of lamp diameter. For example, a T8 lamp is a tubular fluorescent
                       lamp that is 8/8”, or 1” in diameter.

LED                A semi-conductor emits light when charged. LEDs work great as track lights and step

Metal Halide       Electrified gas glows to produce light.
                   • Take a while to heat up
                   • Once switched off, cannot be switched on again until entirely cooled
                   • Cannot be dimmed

Ballast An electrical device used with fluorescent or HID (high intensity discharge) lamps to supply
        sufficient voltage to start and operate a lamp and limit the current during operation.

Sensors Occupancy sensors generally come as either infrared- or sound-triggered devices that
        automatically turn off lighting when spaces are unoccupied.

DALI      Digital Addressable Lighting Interface is a lighting control system that provides a single interface
          for all light sources and controls in a building.

Foot   The illumination of one square foot provided by one candle at a distance of one foot.

Lumen A unit of measurement for light emitted from a single source; based on the intensity of a candle.

Lighting tips

Managing switches and controls is one of the most productive ways to reduce energy. Ask technicians to
       check back to fine-tune lighting controls, to ensure, for example, that lights do in fact adjust
       according to daylight levels.

EPACT, the Energy Reform Act of 2005 encourages envelope efficiency and insulation, and heating,
       cooling, and lighting improvements.
   • Allows 1.3 watts per square foot for most buildings, though more watts / sq ft allowed in retail
   • Provides that if you design to use 40% less energy than the standard for your space, you can take a
       tax deduction of $0.60 per square foot. If the design is in a public building, the designer can take
       the deduction.
   • Enables a developer to receive EPACT money for certain building upgrades
Look for a combination of lamp and ballast designed to work together for the most efficient lumen output.
        CFLs have an internal ballast that is not designed to be as efficient as it could be because it will be
        discarded when the lamp burns out. It is better to use replaceable-lamp ballasts, which are
        designed to produce light more efficiently and last longer.

Fluorescent lamps with pins are better than standard screw-in bulbs because the ballast is external and
        designed to run more efficiently and last longer, related to the point mentioned immediately above.
        Fluorescent lamps with pins are also better because screw-in types can be replaced with
        incandescent bulbs.

The best way to use fluorescent lamps is for ambient light, when the ballast is not visible.

Light the items that you want people to see.

Light merchandise from a 30° angle to minimize glare.

Example of a lighting efficiency measure: 3-lamp conversion to a 2-lamp efficient fixture
       Remove the three old lamps
       Recycle part of the fixture
       Re-use the rest of the fixture
       Add two efficient lamps

1) The above design notes are intended for average spaces. Irregular shaped spaces
   may require more than what is indicated. When in doubt, add or call for assistance.

2) Avoid designing with wall switch sensors. Wall switches are subjected to vandalism and
often their viewing angle is obstructed by furniture.

3) Always include the recommended time delays in the specification.

4) Always start out specifying product with the spare set of contacts. (DT200 VS.
   DT205) This becomes a low cost point of control for other systems in the facility
   today or sometime in the future. (Unit ventilators, VAV boxes, EMS)

5) Remember that there is always more than one way to design a space with sensors.
   Whenever possible, the above recommendations should simply be your first choice.

6) All ceiling mounted occupancy sensors require a power / switch pack. One power
   / switch pack is required per circuit or per control zone.

   Creating A Greener Energy Future For the Commonwealth

                         Commonwealth Energy Resource Teams
The state has put together Commonwealth Energy Resource Teams (CERTs) to help you with your
energy challenges now.

This resource has been created to assist Commonwealth businesses with a one-stop-shop resource
for energy users. To start, DOER recommends you leverage all existing utility and state programs
and integrate them into a comprehensive organization-wide energy plan. Below are the steps you
should follow:

A) Leverage Existing Programs ...

1) Utility Energy Efficiency Programs

In Massachusetts, electric and gas distribution companies and municipal aggregators offer programs
to help you invest in energy efficient products and services for your business. DOER urges
customers to make existing utility programs a part of their comprehensive energy planning.
Customers in the area served by the Cape Light Compact should contact CLC directly. Customers
served by municipal power and light (MPL) departments are urged to contact their MPL directly.

        GasNetworks Rebate Applications: DOER recommends for business customers to review the
        programs featured at GasNetworks. Individual member companies of GasNetworks may
        offer utility specific energy efficiency and rebate programs. Although these programs will vary
        from company to company, they all provide energy savings for GasNetworks customers.

2) Renewable Energy Grants

The Massachussetts Technology Collaborative has numerous grant opportunities for customers in the
investor owned utility territories (customers served by municipal power and light (MPL) departments
are not eligible).

        Commonwealth Solar: A new initiative, Commonwealth Solar provides rebates through a non-
        competitive application process for the installation of PV projects at residential, commercial,
        industrial, and public facilities. Go to the website for the steps to apply.

        Other MTC Funding for Renewable Energy: The MA Technology Collaborative's Renewable
        Energy Trust funds eligible renewables through a variety of programs for small and large
        renewable energy projects.

3) Free Site Assessments

        The Industrial Assessment Center (at UMass Dartmouth) provides free assessments for
        certain industrial and commercial customers. Contact the IAC, a MA DOER sponsored
        program, to determine if your site would be eligible for a comprehensive energy audit (more
        than just an electricity audit).

        The Northeast Combined Heat and Power Application Center is a MA DOER sponsored
        program to help end-users determine if their site is a good candidate for combined heat and

4) State and Federal Tax Incentives
The DOER website features State and Federal tax incentives for renewable energy and efficiency.

5) Energy Training and Workshops
The MA Energy Efficiency Partnership (MAEEP) supports deployment of energy efficient technology
and tools to the industrial, commercial, and institutional sectors. The MAEEP Program delivers its
value through a combination of stakeholder input, technology transfer, education and outreach, and
research. Go to the MA EEP website for a calendar of trainings:

B) Use Existing Resources ...

1) Comprehensive Energy Audits
First leverage the energy audits available from the utilities and currently available assessments
(above). Then, choose an Energy Service Company (ESCo) for a comprehensive energy audit
and/or performance contracting. A list of ESCO’s is available at the website of the National
Association of Energy Service Companies.

2) Energy Tracking Tools
The EPA EnergyStar Portfolio Manager is an interactive energy management tool that allows you to
track and assess energy and water consumption across your entire portfolio of buildings in a secure
online environment. Whether you own, manage, or hold properties for investment, Portfolio Manager
can help you set investment priorities, identify under-performing buildings, verify efficiency
improvements, and receive EPA recognition for superior energy performance.

3) Electricity from Licensed Suppliers
Companies should consider getting their electricity supply from a licensed electricity supplier. Get a
list of licensed suppliers available at the DPU Website and if you have high energy use during off-
peak times ask a supplier about their real-time pricing options.

4) Other On-Site Clean Energy Information Resources

        DOER has a Renewable Energy Programs page on its website.

        DOER provides technical assistance for customers seeking to install on-site power
        generation, such as solar or wind. Installers can manage the interconnection process with
        the utility. But, if you need help, contact a DOER representative to learn more about the
        process. Access the Interconnection Guide for Distributed Generation, a new web resource
        produced by MTC and DOER.

        Renewable Energy & Distributed Generation Guidebook: A developer's guide to regulations,
        policies, and programs that affect renewable energy and distributed generation facilities in
        Massachusetts. This resource Includes siting and advice on renewable energy purchase and
        sale agreements.

C) Schedule a CERT Intake Interview ...

Contact DOER to plan your comprehensive energy strategy or if you would like assistance enrolling
for each of the existing programs. Provide a profile of your primary business and energy usage and
the CERT will assign the best additional assistance for you and provide help on an ongoing basis.
