• 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.

• Sky Factor
Daylight Concerns:
15
• 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.)

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.

What is Daylight
Harvesting?
33
What is Daylight Harvesting?
34
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.
Daylight Harvesting
Techniques
35
Daylight Harvesting: Open Loop Systems
36
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

• 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

Example #2
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

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.
Daylight Switching
Vs. Daylight Dimming
40
Daylight Harvesting: Switching or Dimming?...
41
Recommended for:
Day lit spaces where non-detailed tasks take
place (ie: warehouse, factory, gym)
Day lit spaces where switching is not
distracting
Daylight Bi-Level Switching
Advantages
• 3+ levels of lighting
• Cheaper than full dimming
• Additional energy savings
Disadvantages
• Somewhat distracting
• Additional ballast(s) &
wiring needed
• Additional cost vs switching
Daylight Harvesting: Switching or Dimming?...
42
Recommended for:
Day lit spaces where detailed tasks are being
performed (Classrooms, Labs, Office Spaces)
Day lit spaces where exact fc levels are needed
Daylight Dimming – Unlimited levels of daylight can be reached.
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
Daylight Harvesting
Codes
43
Daylight Harvesting Codes: ASHRAE 189.1 - 2010
44
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 90.1-07
Peak Load Shedding: In addition, buildings must contain
automatic demand-response systems enabling peak electric
demand to be reduced by at least 10%.
Daylight Harvesting Codes: ASHRAE 90.1 - 2010
45
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 ft2
Side Lighting: (Vertical Glazing)
- Applied if sidelit area is >1000ft2

Daylight Responsive Control
+ C405.2.3
• 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
Daylight Harvesting
Controls &
Commissioning
47
Daylight Harvesting Controls: Photosensors
48
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
Daylight Harvesting Controls: Direct Method vs. Processors
49
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.
Direct Method - Wiring the lighting ballast & photocell together.
Typical for some open-loop systems. Extreme limitations in
control capability. Not recommended
Daylight Harvesting: Commissioning Terminology
50
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, 30-3000, 60-6000, etc.)
(Sensor voltage output to light level relationship needs to be defined in the system)
The following settings are common parameters when configuring the
operation of a daylight harvesting system:
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…
…Integrated Building Technology.

The IBT Solution
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
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.
Non-Integrated Example
• He sends out meeting invite via Outlook Calendar
• Emails 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 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
Integrated Example
• Sends out meeting invite via Outlook Calendar
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
• 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
Buildings perform better. Buildings save energy.
