Sensors and Controls

Southland Industries offers a variety of innovative lighting control technologies, including those that integrate occupancy control and logging, tying into building management systems and simultaneously controlling lighting and ventilation. “This is something we have been doing to decrease the number of sensors needed to reduce lighting levels and control ventilation levels at the same time,” says Bridgette Rodgers P.E., energy engineer.

Rich Paroby, P.E., project developer, adds that a similar innovation is using controls to integrate lighting and plug loads wirelessly at the individual workspace level.

Southland Industries has both radial, relay-based topologies to topology-free systems, both utilizing PC- and Web-based scheduling controls to offer both local and remote communications, says Michael Starego, P.E., associate principal electrical engineer. “Topology-free systems offer distributed, addressable, and intelligent devices that—wired or wireless—tie into a central network for local or Web-based control and data logging,” says Starego. “Our innovative use of wireless control technologies allows for greater opportunities with decreased cost, reducing both material and labor requirements, while also providing the same benefits and capabilities of traditional wired systems.”

Seth Pearce, P.E., director of engineering and development, quips that the company’s services are becoming more “tactical” in approach. “We’re performing innovative logging utilities with our advanced occupancy sensing designs that offer movement tracking and identify high-use areas,” he says.

The company’s use of dual technology sensors and controls (infrared and ultrasound) have eliminated false occupancy sensing and improved systems’ operation and function. “Coupling smart systems with sustainable innovations utilizing solar, skylighting, and daylight harvesting technologies to further decrease energy consumption really tops the cake,” says Pearce.

Facilities with windows or skylights benefit from natural lighting and supplement non-natural lit spaces using efficient technologies, says Warren Van Ryzin, P.E., project developer. “Daylighting control and automation innovations sense the amount of natural lighting and dim or shut off lighting equipment in a daylit space to provide the proper amount of work area foot-candles per the Illuminating Engineering Society [IES],” he adds.

Southland Industries offers the ability to enhance control scheduling with multiple data algorithms, analytics, and end-user adaptability. “We’re a bit naturally innovative, because we’re product-agnostic,” says Pearce. “This enables a lot of exposure to different solutions and allows us to optimize the solution for the purpose.”

To this end, Paroby adds, “we are really leveraging the increased availability of open protocol controls now available to maximize innovation without some of the limitations of proprietary control systems.”

Southland deals with environment-specific innovations that include automatic daylight controls integrated into either radial control or topology-free systems. This provides intelligent device systems to make buildings and energy use “very smart,” notes Pearce.

“Southland also is innovating with individual fixture control, offering end users the ability to control their individual area to their own lighting level preference for increased comfort and performance,” says Van Ryzin. “These innovations, coupled with others such as vacancy sensing, high-end tuning, and demand response capabilities are providing great energy savings.”

The company’s value-oriented solutions consider lifetime maintenance cost, best IES of North America practice, integrated HVAC, space usage, and appropriateness of the lighting system to exceed the project objectives,” says Starego.

“Our transparent and experienced development teams look at projects as partnerships that simplify need, safety, and satisfaction,” adds Pearce.

Southland performs turnkey service for its customers. “Numerous lighting technologies, controls options, and alternate lighting sources are engineered and developed to understand the overall cost of ownership of our customers’ systems,” says Van Ryzin. “A holistic approach to the available lighting solutions and noodling out the feasibility of each technology is how we determine if, where, and what products meet the project objective.”

Southland’s energy modeling capabilities and advanced simulations offer detailed analysis designed to determine baseline energy use, explore simulated scenarios, or computationally model the most sensitive environments such as an art exhibition, datacenter, or scientific research.

“Our lighting pros work closely with our comprehensive design/build engineering staff to be able to coordinate design with all other trades and designs. And our Building Information Modeling offers the ability of architects and owners to view what rooms look like with the future of lighting,” says Eddie Sladek, P.E., energy engineer. BE_bug_web
