4 4 What is Daylighting?

5 What is Daylighting? Daylighting s objective is to minimize the amount of artificial light thereby reducing electricity costs. Daylighting is the practice of placing windows or other openings and reflective surfaces so that during the day natural light provides effective internal lighting. Daylighting can also lower HVAC costs. Properly controlled natural daylighting generates hardly any heat compared to its electrical lighting counterpart. 5

13 13 Daylighting Concerns

14 Daylight Concerns: Sky Factor Clear Sky Partly Cloudy Overcast 14

15 Daylight Concerns: Sky Factor Amount of sun varies every day Number of days of sun per year varies with every city Sunnier cities will have higher ROI and faster payback than others Control system needs to be commissioned appropriately for the climate type Commissioning requirements should be included in the programming scope and the CSI specifications to suit the clients expectations Example: Miami has quickly passing clouds, select a slower Response time (2min.) Seattle has slowly passing clouds, select a faster Response time (30 sec.) 15 Clear Sky Partly Cloudy Overcast

16 Daylight Concerns: Sky Factor Building Orientation 16

17 Daylight Concerns: Sky Factor Building Orientation South-facing windows are most advantageous for daylighting and for moderating seasonal temperatures. They allow most winter sunlight into a building but little direct sun during the summer, especially when properly shaded. North-facing windows are also advantageous for daylighting. They admit relatively even, natural light, producing little glare and almost no unwanted summer heat gain. Although east- and west-facing windows provide good daylight penetration in the morning and evening, respectively, they should be limited. They may cause glare, admit a lot of heat during the summer when it is usually not wanted, and contribute little to solar heating during the winter. 17

18 Daylight Concerns: Sky Factor Building Orientation Obstructions 18

19 Daylight Concerns: Sky Factor Building Orientation Obstructions Understand that ROI for a project in a city with buildings in close proximity will vary from the same building in a rural setting or in a less crowded environment 19

20 Daylight Concerns: Sky Factor Building Orientation Obstructions Solar Heat Gain 20

21 Daylight Concerns: Sky Factor Building Orientation Obstructions Solar Heat Gain Low SHGC glass (Solar Heat Gain Coefficient) Low U-Factor Glass (Heat Flow through the window) Low AL (Air Leakage) Install Manual or Motorized Shades!!!!!! Install multiple layers of shades 21

22 Daylight Concerns: Sky Factor Building Orientation Obstructions Solar Heat Gain Glare Too permanent, ruins façade of the building Makes it hard to work 22

23 Daylight Concerns: Size windows properly Sky Factor Building Orientation Obstructions Solar Heat Gain Install Manual or Motorized Shades!!! Glare 23

24 Daylight Concerns: Sky Factor Building Orientation Obstructions Solar Heat Gain Glare 24 Summer solstice, southern latitude Winter solstice, southern latitude Install Manual or Motorized Shades!!! Consider 2 layers of shades to correctly manage daylight: - translucent fabric - black out shades Solar Tracking Install manual override Integrate with lighting control & AV scenes within the room

26 Daylight Concerns: Sky Factor Building Orientation Obstructions Solar Heat Gain Glare energy savings > the price tag? What is the Return on Investment (ROI)? 26

27 Daylight Concerns: Sky Factor What is the true ROI for Daylight Harvesting? Building Orientation Obstructions Solar Heat Gain Glare What is the Return on Investment (ROI)? Part 1 The cost ($) of the Daylight Harvesting System Part 2 The value ($) in Energy Savings Part 3 The value ($) of Happy Tenants priceless > $0.00 then a Positive Return on Investment! 27

28 28 Daylighting Study

29 In a recent study by Lawrence Berkeley National Labs they attempted to answer two very important questions related to Daylight Harvesting Where are the Primary & Secondary Daylighting Zones located? How much Energy is saved in each Zone? 29

30 Daylighting Study: Vertical Glazing: Primary & Secondary Zones 9 6 Primary Zone Secondary Zone Third Zone Primary Zone Secondary Zone 0 to (10-15 ) (10-15 ) to Example 1 Example 2 30

31 Daylighting Study: Horizontal Glazing: Primary & Secondary Zones h x 70% Skylight h Secondary Zone Primary Zone h x 70% Secondary Zone Larger quantities of light than Vertical Glazing, but lacks views to the exterior Cannot be used for LEED Indoor Environmental Quality Credit

32 Daylighting Study: Energy Savings In a recent study by Lawrence Berkeley National Labs, they compared the energy for one year from a space with daylight harvesting to a space without daylight harvesting and found Example B: LBNL Study - 9 Glass Walls, all 4 sides of the building - Low Partition, Open Work Stations - Daylight Dimming Techniques used Primary Zone Energy Savings: West facing walls - saved 30% NW & SW facing walls - saved 50-60% Secondary Zone Energy Savings: West facing walls - saved 10% NW & SW facing walls - saved 25-40% % Energy Savings % Energy Savings

33 What is Daylight Harvesting? 33

34 What is Daylight Harvesting? A control system used in sustainable architecture that reduces the use of artificial lighting with electric lamps in building interiors when natural daylight is available, in order to reduce energy consumption. 34

35 Daylight Harvesting Techniques 35

36 Daylight Harvesting: Open Loop Systems Open Loop Sensor: Example #1 The photosensor detects the amount of available daylight only It can be positioned: on the building's exterior wall or roof or inside the building facing the skylight 35 Skylight h 35 Typical Open Loop Photosensor h x 70% Example #1 h x 70% 36

37 Daylight Harvesting: Open Loop Systems Open Loop Sensor: Example #2 The photosensor detects the amount of available daylight only It can be positioned: on the building's exterior wall or roof or inside the building facing the skylight or inside the building facing the window Allows multiple zones of fixtures to be controlled with a single photosensor h Typical Open Loop Photosensor h 2h Example #2 37

38 Daylight Harvesting: Closed Loop Systems 38 Closed Loop: The photosensor detects the combination of daylight and electric light It should be positioned: away from direct sunlight away from direct artificial light where it can measure reflected light off a surface from both the natural and artificial light Allows you to define a single set point and vary the zones to achieve it Each independently controlled zone requires a photosensor h Typical Closed Loop Photosensor h Example 2h

39 Ten Design Principles for Daylighting Configure room so that occupied floor area is within daylighting zones, typically about 15 feet from the window wall or below skylights. Elongate wings of the building on east/west axis to avoid glare and solar heat gain Bring the light in high. Windows high on the wall allow light to penetrate further into the space. Use skylights to daylight areas without easy access to windows. Let daylight in from more than one side of the room when possible. Provide views where appropriate, but diffuse or block direct sunlight to avoid glare/heat. Use light colored interior surfaces to reduce luminance contrast and improve coverage. Control first costs by avoiding excessive glazing. Promote daylighting behaviour within the building by educating occupants to open blinds when possible. Use automated controls to dim or switch off electric light when daylight is sufficient. 39

40 Daylight Switching Vs. Daylight Dimming 40

41 Daylight Harvesting: Switching or Dimming?... Daylight Bi-Level Switching Recommended for: Day lit spaces where non-detailed tasks take place (ie: warehouse, factory, gym) Day lit spaces where switching is not distracting Advantages 3+ levels of lighting Cheaper than full dimming Additional energy savings Disadvantages Somewhat distracting Additional ballast(s) & wiring needed Additional cost vs switching 41

42 Daylight Harvesting: Switching or Dimming?... Daylight Dimming Unlimited levels of daylight can be reached. Recommended for: Day lit spaces where detailed tasks are being performed (Classrooms, Labs, Office Spaces) Day lit spaces where exact fc levels are needed Advantages Exact fc level can be maintained at all times Most comfortable for clients Highest energy savings Disadvantages $ Dimming ballast/driver needed Commissioning may require more time 42

43 Daylight Harvesting Codes 43

44 Daylight Harvesting Codes: ASHRAE Automatic Lighting Controls - expanded to include: - daylight harvesting - manual-on and bi-level occupancy sensing - bi-level switching in some stack and egress and outdoor applications. Submetering: Major building systems such as HVAC & lighting are required to be submetered and the data fed to a data acquisition system for storage and later retrieval. On-Site Renewables: Buildings must provide for future installation of on-site renewable energy systems. LPD: Lighting power densities capped at 90% of those in Peak Load Shedding: In addition, buildings must contain automatic demand-response systems enabling peak electric demand to be reduced by at least 10%.

45 Daylight Harvesting Codes: ASHRAE Daylighting Requirements: Developed in conjunction with Title 24 Requires the installation of skylights when appropriate Daylit areas must have multi-level control: At least 2 levels of output, 0-35% & 50-70%, All On Or Continuous Dimming Top Lighting: (Skylights & Rooftop Monitors) - Applied if daylight area under skylight and rooftop monitors is >4000 ft 2 Side Lighting: (Vertical Glazing) - Applied if sidelit area is >1000ft 2 45

46 Daylight Responsive Control + C Daylight harvesting required: Spaces with >150W general lighting within daylight zone Exceptions: healthcare, dwelling/sleeping units, food/drink consuming areas, shops and stores. Exception: area of fenestration is <24sqft Exception: distance from fenestration to nearest obstruction is shorter than the distance from the bottom of the fenestration to the top of the obstruction The daylight harvesting controls must be readily accessible The daylight harvesting controls must be capable of being calibrated within the space they are affecting 2015 Crestron Electronics, Inc.

47 Daylight Harvesting Controls & Commissioning 47

48 Daylight Harvesting Controls: Photosensors Photosensors Used to measure the quantity of daylight in the space then determine the amount of dimming or switching required to maintain the design work plane illuminance level. Typical Open Loop Photosensor Typical Closed Loop Photosensor 0-10V signal 3-300, 30 to 3000, or 60 to 6000 footcandle range 0-10V signal Measures 0-70 footcandles 48

49 Daylight Harvesting Controls: Direct Method vs. Processors Direct Method - Wiring the lighting ballast & photocell together. Typical for some open-loop systems. Extreme limitations in control capability. Not recommended Processor Method - A processor is the brains of a Daylight Harvesting control system. It receives data input from the photocell and then sends a signal to: - the ballast or light fixture to turn on/off/dim - keypads and/or touchpanels for override - facility energy management & monitoring system - shade system * It also makes it easy to commission and change the settings of the photocell remotely as needed. 49

50 Daylight Harvesting: Commissioning Terminology The following settings are common parameters when configuring the operation of a daylight harvesting system: Response Time defines how quickly the system reacts to changes in light levels Minimum Dim Level defines the lowest level a dimmer may output (can be used to prevent the lights from turning completely off when dimming) Dim Level To Photosensor Relationship (Open-Loop) defines dimmer output levels in relationship to open-loop photosensor readings Desired Light Level (Closed-Loop) defines the desired light level in the space Photosensor Range set photosensor fc range (3-300, , , etc.) (Sensor voltage output to light level relationship needs to be defined in the system) 50

51 To Think About There are various techniques available to incorporate daylight harvesting into a commercial project The benefits of daylight harvesting (including energy savings) outweigh any of the prior concerns due to the new technology, programs, & simple commissioning tools that are now available from various manufactures The only way we will truly reach future sustainable goals is to integrate Daylight Harvesting into more than just lighting, and then look at the big picture 51 Integrated Building Technology.

90 The face of Energy Monitoring is changing

91 The face of Energy Monitoring is changing WHY? We re not just gathering energy data anymore. We re analyzing it, we re integrating it with other building systems, and we re required to save more energy than ever before!

92 Data in Control out!

93 Benefits of a single platform solution Centralized Control A single location for facility managers to conveniently view and manage lighting, shades, occupancy status, current temperature, and alarms for individual rooms, floors, and buildings A single location for facility managers to remotely access preprogrammed system touch screens

94 Benefits of a single platform solution Centralized Control Scheduling & Automation A single location tied to an astronomical timeclock where facility managers can modify and create newly scheduled events A centralized energy management control system that integrates seamlessly with corporate scheduling software such as Microsoft Outlook or Lotus Notes for an added layer of energy savings capability A single location for programming lighting, shade, & hvac automation rules tied to scheduled meetings and events

95 Benefits of a single platform solution Centralized Control Scheduling & Automation Monitoring & Reporting A single location for gathering real-time energy data of true power consumption & power factor A single location for gathering feedback information from lamp and ballast failures as well as room status A single platform to not only monitor & report energy consumption from electricity, but also from natural gas, steam, petroleum and other energy categories as needed

99 The IBT Solution Drape/Screen Lighting Energy Mgt Every system working together. AV Control Remote Mgt HVAC & Climate Control Security

100 Non-Integrated Example The President of a fortune 500 company schedules an 9:00am meeting, in the summer, to be held in the conference room and wants to present a power point He sends out meeting invite via Outlook Calendar s IT department to prepare the room which includes: setting up & turning on the projector, manually closing the blinds, adjusting the thermostat to pre-cool the room down to prepare for a large group of people, and turning the lights on The meeting is cancelled at the last minute, but the IT department is not notified. The lights & projector remain on for the rest of the day. The blinds remained closed. The HVAC system continues to cool an unoccupied room. Other employees would like to use the conference room later on in the day, but go elsewhere because they are not sure if there is a meeting about to begin in the conference room or not.

101 Integrated Example The President of a fortune 500 company schedules an 9:00am meeting, in the summer, to be held in the conference room and wants to present a power point Sends out meeting invite via Outlook Calendar 5 minutes before the meeting is to begin, the room automates to a pre-programmed AV Presentation preset. The lights go to a preset scene, the projector warms up, the blackout shades close, and the room pre-cools itself down to a pre-determined set point temperature for an occupied space The meeting is cancelled at the last minute. At 9:10am the room s occupancy sensor senses no presence & sends a signal to the building s Energy Management System which automatically turns the lights & projector off, the motorized blackout shades open, the hvac system stops cooling and returns to an un-occupied set point temperature, and the Outlook integrated touch screen next to the door indicates the room is Open and others may use it

102 IBT Benefits Buildings perform better. Buildings save energy.

103 The new design questions Can we select efficient individual building energy systems? Can we integrate control of these individual systems to together to save even more energy?... Can we make it easy for the facility manager to use and continue to save energy?... Can we design more efficient buildings than ever before?... When do we start?...
