Quantum energy savings and light control strategies Photography Nic LehouxArchitectural load dimmingLight level tuningDaylight harvestingAllows the users to dim traditional light sources such asincandescent, halogen, low voltage, and LED.Sets the target light level based on customer requirements ineach space. This level is lower than the high-end trim light level.Automatically adjusts the electric lighting levels based on theamount of daylight in the space.Fluorescent dimmingScene and zone controlSchedulingRemote monitoring and controlHighly efficient dimming that allows the users to dimfluorescent lights.Users can select pre-programmed light scenes or raise andlower individual light zones.Lights turn off or are dimmed and shades are adjustedautomatically at certain times of the day or in relation tosunrise and sunset.Allows management of your building’s light from anywherein the world.Controllable window shadesScene controlAllows quiet control of daylight for improved comfort andproductivity using Sivoia QS shades.Users can select pre-programmed light scenes at the touchof a button.SwitchingPersonal light controlAutomatically adjusts Lutron Sivoia QS window shadesbased on the angle of the sun to maximise the effective useof daylight.Allows the user to switch on or off all non-dimmed lightsources using 1 million cycle relays.Allows users in the space to select the correct light level forthe desired task.

Green Glance softwareGreen Glance displayed on a user-supplied LCD screen How green is your building?Demonstrate your company’s commitment to energy efficiencywith Green Glance energy-saving display software.Green Glance software provides a quick snapshot of your building’s energy savingsfrom using the Quantum total light management system.Building owners and facility managers can use Green Glance to motivate employeesto save energy, or to support their organisation’s reputation for being green and sociallyresponsible. They can also use Green Glance as an educational tool to display theirfacilities’ economic and environmental benefits from using Quantum, such as moneysaved, CO2 not emitted, or tons of coal preserved. Furthermore, they can use GreenGlance software to display any other green facts about their building such as detailson waste reduction programs or water efficiency systems.14Lutronwww.lutron.com/europeAverage lighting energy savedover user-selected period.Displays lighting energyand environmental savingsMaximum potential savingsDisplays project details and lightingenergy calculation informationUser can select pre-defined spacesUser-selectable time periodsfor lighting energy displaysDisplays local conditions(requires internet access)www.lutron.com/europeReal-time lighting powersaved by using Quantum Building local time and dateCompares lighting energy savings ofdifferent time periodsLutron15

Hyperion solar-adaptive shading Before:After:The afternoon sunmakes it difficult towork productivelydue to heat andglare in the space.With Hyperion solar-adaptiveshading, the windowshades automatically closewhen the sun reaches acritical angle – making thespace more comfortable byreducing glare and heat whilemaintaining the view outside. s the sun moves throughout the day, Hyperion solar-adaptive shadingAautomatically adjusts the shade position without the requirement for acomplex array of external sensors. The Lutron out-of-the-box solutionallows simple set up based on the building’s geographic location and userspecified sunlight penetration.The benefitsWhat it doesmaximises effective daylightincreases comfort and reduces glarepreserves external views creates an aesthetically pleasing exterior byperfectly aligning shades10-30% reduction in solar heat gain13-29% reduction in heat loss1 yperion solar-adaptive shading automatically adjusts window shades based on the sun’sHposition throughout the day to effectively manage the daylight in your building, reduce glare,and save energy.1 Lutron commissioned simulation byT.C. Chan Center for Building Simulation and Energy Studies,University of Pennsylvania, September 2008.16How it worksLutron he system operator inputs the desired sunlight penetration distance into the building andTthe number of shade preset positions. Then, Hyperion solar-adaptive shading automaticallycalculates the angle of the sun and adjusts the shades to maintain the preferred lightpenetration.Additionally, manual override – via simple keypads or handheld remote– allows the user to adjust an individual window shade if required.Compared to sensor based shading systems, the Lutron systemprovides less movement and less distraction to occupants.Shade: ClosedShade: Preset (Open 50%)Shade: OpenAt sunrise the light and heat penetrate thebuilding so the shades remain closed forcomfort and energy savings, while still havingaccess to the view.The sun angle is higher so shades open topreset position to maintain the customer desiredsunlight penetration, and to reduce glare.Sun angle is at a point where glass reflectsa majority of the heat, plus light penetrationis limited to 2 – 3 ft. into the building. Shadesautomatically open to allow maximum useof effective daylight.At night the shades are lowered to minimise light pollution and provide a uniformappearance with precision alignment. The system also provides the ability for the user tomanually override and adjust the shades to a custom tron17

Q-Admin software highlights Beyond light control to light managementThe heart of the Quantum solution is Q-Admin—Quantum’spowerful software that allowsfacility managers to managetheir electric light and daylightfor maximum energy efficiency,comfort, and productivity. From acentral location, a facility managercan not only control electric lightsand shades but also configure,monitor, analyse, and report on thelight in an entire building.TimeclocksQ-Admin software includes twotypes of timeclocks, a time-of-dayclock (e.g. 8pm weeknights) andan astronomic clock (e.g. dawnor dusk), which control the lightsand shades on the Quantum network. Lights can automaticallybe set to a preset level or turn onor off in certain spaces based onthe time of day; and shades canautomatically raise or lower incertain spaces at specific times.Control and monitor llows you to control and monitorAany space in your building by areascene, area level, or individual uropeLutron19
