4 Page 4 1 Description 1.1 Introduction This design guide helps lighting designers to make the light plan, using GreenParking. It shows all the possibilities, tips and tricks, and will help to make the best decisions for your specific situation. 1.2 GreenParking GreenParking, is a LED lighting system that provides the best lighting and reduces the energy and maintenance costs for (covered) car parks. The massive savings are achieved by LED technology and the addition of motion sensors. These motion sensors detect if people or moving cars are present in a certain area and if not will dim the lights. Dimming saves quite a lot of energy (up to 80%) and avoids dark areas. The remaining light level is more than enough for orientation and a safe feeling. The system is easy to commission and requires no special tools other than a simple hand held remote control. GreenParking includes IP66 wireless Pacific LED luminaires (with or without integrated motion sensor) and IP65 wireless external battery powered motion sensors. The Pacific LED is especially designed for retrofit, but can be used in newly build car parks just as easy. The LED technology increases the maintenance cycle by at least a factor 3 up to 10 years compared to conventional lighting. GreenParking includes three basic components: a Luminaire with integrated motion sensor b Luminaire c External battery powered motion sensor with IP65 housing All the components have wireless connectivity. A remote control is required for commissioning. See Appendix A for the specifications of the different components. Each component comes in different models. For example, external battery powered motion sensor models include a ceiling sensor, corner sensor, pathway sensor and wall sensor. A GreenParking network can be configured with three different modes: standard setting (default), economic setting, and comfort setting. The standard setting offers the best mix between saving and comfort. The economic setting offers maximum saving on energy costs. The comfort setting offers the most comfortable lighting. It is possible to have emergency lighting combined with GreenParking. 1.3 Working principle In GreenParking all the different components make contact with eachother through a wireless connection to propagate occupancy information. The connected components together will form one or multiple networks. When motion is detected, the light level will be 100%. When no motion is detected for a specific time, the light level will dim to background level.

5 Page 5 GreenParking can be installed in closed parking garages by combining the three basic components in the following ways: 1 Using only luminaires with integrated motion sensor 2 Using luminaires and luminaires with integrated motion sensor by placing them in an interspersed manner. 3 Using luminaires and external battery powered motion sensors by placing the motion sensors at strategic locations. In cases 1 and 2, external battery powered motion sensors can be used to enable occupancy detection in spots where it is difficult to place (mount) luminaires with integrated motion sensor and wireless connectivity.

6 Page 6 2 Design your GreenParking This design guide helps to choose the settings of GreenParking that will best suit your needs. Take all the settings and parameters that can influence GreenParking behavior into consideration Networks in a parking garage 2.1 Networks GreenParking can combine luminaires to form a network. All the luminaires in a network will react in the same way. If GreenParking detects motion in the network, all the luminaires in that network will switch on to 100% One network In one network, the luminaires are in one mode. All the luminaires will react on motion detection, as set by the current mode, in the same way. 100% 0 min 10% 2 min Follow the use of the parking garage: routing of cars including adjacent parking lots routing of people Within a parking garage the use of a lot of small networks will give high energy saving, the use of larger networks will give high comfort of light. Determine the network size that is best for the situation and meets the preferences of the customer. One network in a parking garage Multiple networks When you create two or more networks, the luminaires in another network can be set in a different mode. Luminaires will only react on motion detection in their own network. 100% 0 min 10% 2 min 2.2 Modes A mode defines in which way the luminaires will react to motion. For GreenParking three different modes can be set: standard setting (default), economic setting and comfort setting. Standard setting (default) GreenParking keeps the luminaires on for 4 minutes. This is the default setting of GreenParking. The luminaires will dim to background light level (20%) when the network is vacant. Two networks in a parking garage 100% 255 min 20% 5 min Economic setting GreenParking keeps the luminaires on for a minimum of time (2 minutes). Use this setting when the time that people are present in a zone is short. The luminaires will dim to minimum background light level (10%), when the network is vacant.

7 Page 7 Comfort setting GreenParking keeps the luminaires on for a longer time (6 minutes). Use this setting when the time that people are present in a zone is longer. The luminaires will dim to maximum background light level (30%) when the network is vacant. 2.5 Map the traffic: cars and people 2.3 Steps to design your GreenParking The following steps have to be followed: 1 Make the lightplan - chapter Map the traffic: cars and people chapter Define the network chapter For each network make the sensor plan - chapter Make the light plan For people walking: start with mapping the formal routings of people include alternative routes that are frequently used For cars: start with mapping the formal routings of cars 2.6 Define the networks Ensure to make a light plan according to the guidelines in chapter 3. At the entry of a network sufficiently illuminate all directions (> 10 m). Networks follow the official routes in the garage, priority on cars. Networks follow logical interior shapes (isles, walls, etc). Area length should be between 20 and 40 m length Networks width at least the aisle and bordering parking spaces.

8 Page Make the sensor plan for each network Project the routings on the areas. For each area identify the points of entry for cars and people Sensor plan for external battery powered motion sensors Place a sensor at each point of entry for people: - when entering the car park at the edge of the area - the detection area should overlap the adjacent area by 1-3 m Place a sensor at each point of entry for cars - the detection area should overlap the adjacent area by 2-5 m 2 Place sensors at each route in time response more costly medium coverage B A 3 Place large area sensors in time response large coverage C Optimizing sensors for people In case people may follow multiple or undefined routings two policies can be applied: Optimizing sensors for cars In case cars approach an area from more than one direction, three policies can be applied: 1 Place a sensor right at the entrance late response to presence low coverage 1 Place sensors above each route more costly limited coverage optimal sensor location

9 Page 9 2 Place a corridor sensor to cover a long area less costly large coverage be aware of blocking objects (cars parked, building structure) Increase comfort of light In case an area can only be entered from one end, the light may start to dim before people have left the area, creating uncomfortable situations. This can be prevented by placing supporting sensors. c Place a large area sensor in the far end supports only local presence limited coverage Sensor plan for integrated motion sensors In the figure below, the detection area of a ceiling mounted luminaire with integrated motion sensor is shown. The detection area dimensions define the amount of luminaires with integrated motion sensor which are required for appropriate motion detection mounting height: typical 2.4 m, max. 4.0 m 360 Diameter typical m a Place a pathway sensor in the length direction high coverage b Place a pathway sensor in the cross direction. secure second trigger will give additional time low coverage

10 Page 10 3 lines Luminaires and sensors must be placed at the correct position, to make the communication with other luminaires possible. Therefore, general guidelines and specific guidelines for the different situations are described. Use these guidelines to design your GreenParking in the best way Blocking objects Uneven ceiling 0.5 m 3.1 General guidelines 0.1 m This section describes the general guidelines for GreenParking which are applicable for luminaires with and without integrated motion sensor Maximum components in one network A maximum of 50 luminaires and 10 external battery powered motion sensors can be combined in one network Distance between the luminaires Do not install the luminaires close to concrete or metal constructions. Concrete construction wall D1 < 5 m D2 <10 m C The maximum distance (D1) between two luminaires in a corridor situation is 5 m. The maximum distance (D2) to the next luminaire is 10 m This offers an extra communication possibility. B A Distance to a wall 0.3 m The luminaire A can communicate around a blocking object, if the distance between the luminaires B en C is less than 10 m. The minimum distance from a wall is 0.3 m.

11 Page 11 Concrete construction ceiling It should be noted that the luminaires placed very close to columns (<1 m) can reflect the high frequency signal and can influence the detection pattern. The luminaire with the integrated motion sensor should be positioned in such a way that the occupants of the room are inside the detection pattern as shown in the figure below. When the luminaire is mounted against the ceiling, the recommended ceiling height of the sensor head is 2.4 m. 2.4 m 360 A concrete beam might block the communication of the luminaire. Metal door C Luminaires with integrated motion sensors can be combined with external battery powered motion sensors. This should be done in some situations where the detection range of the systems needs to be increased, and in situations where the luminaires cannot be installed at a place where detection is still needed. B A As the sensor detects movements also through many non-metal materials, take care of the following guidelines: A metal door might block the communication of the luminaire. 3.2 Guidelines for luminaires with an integrated motion sensor The integrated motion sensor mounted in a luminaire has superior detection in hard surfaced areas such as concrete environments like parking lots, cellars, stairwells and hallways. A luminaire hanging next to a wooden/glass door or thin wall will detect moving objects behind the door/wall. This can cause unintentionally movement detections.

12 Page 12 Hidden moving parts like e.g. air-conditioning systems can unintentionally activate the sensor. Be aware not to mount the luminaire with the integrated motion sensor near such devices. Vibrating surfaces can cause unintentional activation of the motion sensor. Therefore, it is strongly recommended to fix the luminaire with the integrated motion sensor to a non-vibrating surface. Suspended luminaires can start moving due to draft. This can cause sensor activation. Therefore, it is strongly discouraged to use suspended luminaires with an integrated motion sensor. Metal object might limit the wireless connection. Therefore, avoid metal objects directly in front of the sensor head.

13 Page Guidelines for external battery powered motion sensor When designing GreenParking with external battery powered motion sensors, four different types of motion sensors can be used: ceiling sensor, pathway sensor, wall sensor, and corner sensor. In this section it is described how and when to use these sensors. Moving doors cause activation of the sensor. Therefore, do not install the luminaires with an integrated motion sensor close to moving garage doors Securing contact between sensors and luminaires Every sensor must be able to contact at least 2 luminaires without obstacles. Every luminaire must be able to contact at least 2 other luminaires freely. With these rules, the signal from the sensor has enough alternatives to reach all luminaires. If an obstacle blocks one contact, the system may still operate properly. This depends on size and nature of the obstacle. This needs to be verified at the location for each individual case. It is hard for the integrated motion sensor to detect cars which exceed the 20 km/h speed. Therefore, avoid to mount luminaires with integrated motion sensor in situations where cars can exceed the 20 km/h speed.

14 Page Strategic positioning of the different external battery powered motion sensors Ceiling sensor h h = 2.5 to 4 m 5.4 m D2 7.2 m h = 2.5 m Add a ceiling sensor at every entrance. Add more sensors for extra comfort. Pathway sensor Maximum dimensions of the detection area. Example: ceiling sensors at the entrances of the parking. The luminaires in the network switch on to 100% as the car or a pedestrian enters the parking. The driver has a clear view where to go. top view 6.1 m 45 m side view 2.3 m Add a pathway sensor at a location where a large and rectangular detection area is needed. Add more sensors for extra comfort. Maximum dimensions of the detection area. Example: replace multiple ceiling sensors by one pathway sensor to save money. The luminaires in the network switch on to 100% as the driver turns left. The pathway sensor keeps the luminaires to 100 % as the car drives further down the lane.

16 Page General rules for external battery powered motion sensor plan Place sensors at entrances of the parking garage and areas, based on routing of cars and people. Place supporting sensors (additional detection) only when needed, for instance in large zones with only one entry / exit point. It is not required to cover the complete zone with detectors. Because of the hold time of 2-6 minutes and the fact that the light does not switch off but remains at background level, people will not be in the dark, also when they are not detected during this delay time. The use of (a) supporting external battery powered motion sensor(s) is recommended when there is a high probability that the time a person spends in a zone exceeds the delay time. This means that the light starts to dim before the person has left the zone. Pay attention that cars and objects may block the line of sight of a detector. Do not install the external sensor near a heater For each network make the sensor plan Ceiling sensor Corner sensor Wall sensor 45 m x 6 m Pathway sensor?? m x 6 m Objects may limit the detection range of the (pathway) sensor

17 Page 17 4 Commissioning GreenParking After the GreenParking lighting design is finished, the components need be installed and commissioned. Use the specific remote control to commission GreenParking. Aim the remote at the sensor in the luminaire, and the luminaires will give feedback on your commissioning steps in an intuitive way. The GreenParking commissioning guide will explain the commissioning steps in more detail. On arrival, GreenParking is set in the out of the box mode. The out of the box mode is only active during installation and has the following behavior: 4.1 Out of the box setting for GreenParking with integrated motion sensor Luminaires with integrated motion sensor will have an out of the box behavior with 100% light at the start, and after 15 minutes they will gradually dim to 20%. When motion is detected, the light will again go up to 100%. 4.2 Out of the box setting for GreenParking without integrated motion sensor Luminaires without integrated motion sensor will have an out of the box behavior with always 100% light.
