"Don't buck trends; embrace them," said Dave Pfund, president of tambient, a division of The Lighting Quotient, an architectural lighting manufacturer in West Haven, Conn. "I think both parties set them.
"Because control systems are now part of codes and standards, it's now a matter of where controls make sense," Pfund
"For example, daylighting control can be a lighting strategy in certain types of buildings, occupancy response in another."?
Geography and a locality's regulations play a role, too. ?
"California requires more robust and deep control requirements," Pfund
shared solutions including bringing both switched and unswitched power circuits to the furniture systems, installing inline wireless control relays on selected circuits where the furniture power connections are made and "linking" the relays to room occupancy sensors.
Task and task-ambient lighting is gaining favor, too.
As a result, Pfund
expects ECs to encounter more portable and furniture-mounted office lighting systems.?
A rise in wireless and photo-sensing fixtures?
Photo-sensing fixtures are something all three men are seeing and, in the case of Pfund
, helping develop.
These "smart" luminaires can be linked to room sensors and to each other using simple "learn" and "teach" push buttons.
The technology provides owners with ongoing flexibility in determining how lighting should respond to daylight and occupancy conditions without the cost and complexity of wired control networks. ?
According to Pfund
, whole space and whole building control systems also are adding wireless capabilities.
feels ECs that learn how wireless devices link together and how associated control subsystems can be tied into central building control systems will have a competitive edge.?
"Whether providing lighting fixtures with wireless embedded in them, or wireless-based control systems, [ECs] can be the person who knows how to link it all together.
There remain a couple of different languages or protocols and standards right now," Pfund
said, adding that ECs should become familiar with several platforms and standards.
When it comes to the office, finding the right combination of ambient and task is one of today's lighting challenges, according to Pfund
Saving energy, reducing energy costs, and satisfying the lighting needs of a specific workplace are what he
calls today's "push/pull" considerations.?
"If something moves out of your realm or shifts, try to follow it," Pfund
