Starting Our Lighting Control System

Friday, February 10th, 2012

The lighting control system is a critical component in reducing our energy needs.  We’re installing Schneider Electric’s Clipsal C-Bus system, which is the most advanced and robust lighting control system that we could find.

Although the basic infrastructure has been in place for some time, Bryan started assembling the components and connecting the data network.  Oh, we’re also building a small data center …

East Mechanical Room

The East Mechanical room houses the electrical distribution panels for the East side of the house as well as the Network Gateway East, which is a 12U network rack and is on the backbone to the Network Gateway West.  The electricity generated from half of our photovoltaic system enter the 200 amp panel in the East Mechanical room, which is ‘live’ today.

East Storage Room

Three of the six lighting control panels are located in the East Storage room.  Bryan installed the network connection from the Ethernet to the C-Bus network in one of the three lighting control panels.

Each room that houses lighting control panels also includes a junction box for the C-Bus network.  These junction boxes allow multiple C-Bus connectors to be joined such that only one C-Bus network cable goes into each lighting control panel.

West Mechanical Room

The West Mechanical room houses the two electrical distribution panels on the West side of the house.  As well, all the geothermal and hydronic heating/cooling equipment will be located in the West Mechanical room.

Air Handler Room

The Air Handler Room, which is on the West side of the building, houses two more lighting control panels.  As well, it has a junction box for the C-Bus network backbone, which is connected to the C-Bus network junction boxes in the East Storage room and the Upper Laundry room.

Network Gateway West

We have two network gateways, which are connected on a high-speed backbone.  We installed a temporary 12U rack for the equipment that will, ultimately, comprise the Network Gateway West.

The temporary rack has a Motorola cable modem (for Comcast), a Luxul 2300 HBR router and a gigabit switch.  Bryan bought an APC PDU, which will become our permanent source of power from the 100 amp panel located in the West Mechanical room.

 

Three lighting control panels in the East Storage room. The initial panel is on the right, and has the network interface (Ethernet and C-Bus) and a 12-channel relay.

 

Close up of the initial lighting control panel. The Ethernet and C-Bus network cables are coming through the bottom of the panel.

 

We put the C-Bus network junction up high as it will only need to be accessible if there is a physical network failure. You can see that we are using pink CAT5e cable for the C-Bus network and yellow CAT5e as redundant cabling.

  

Most of our network cabling is run through flexible orange 'smurf' conduit although some of the cabling runs free outside the conduit.

 

The East Mechanical room is cleaned up and all the electric distribution panels are covered and secured. The 200 amp panel on the left is 'live' as half of our photovoltaic system is connected in this panel.
