LHUMAN: Enhancing the Quality of Life With Human-Centric Lighting Control Built for Freedom of Design
Application Type: Luxury Residential
Project Scope: New construction Integrator: Atlanta Home Electronics
Lighting Designer: Light Can Help You
This custom home in Atlanta, Georgia, was built from the ground up to meet every facet of the family’s lifestyle with lighting at the forefront. Utilizing Vantage’s LHUMAN human-centric lighting control solution, lighting design company Light Can Help You and home integration company Atlanta Home Electronics were able to achieve a lighting environment inside and outside the home to meet homeowner Michael Cowart’s desire for a lighting system that changes throughout the day and is centered around life and wellbeing.
The Challenge: Homeowner Michael Cowart discovered in his career as a commercial real estate developer and many visits to their beach home in Costa Rica that lighting has a big impact not only on the aesthetics of a space but also on wellbeing and productivity.
“When you’re at the beach, you really can see the way that the lighting changes dramatically throughout the day,” Cowart said. “Lighting has such a calming effect, especially at sunrise and sunset. Understanding the deeper effects of lighting and how it can change a room or your mood, I wanted to bring that same element into my home.”
What Cowart was looking for is called human-centric lighting (HCL), which uses precise lighting control technology integrated with tunable fixtures to replicate natural light indoors, matching the color temperature and intensity of sunlight over a 24-hour cycle. However, achieving the level of precision required for HCL in a lighting fixture is incredibly complex — and expensive. In order to create and reap the benefits of HCL where circadian cycles play out over the day, historically, homeowners have been limited to specific and costly “smart” lighting fixtures from other lighting control manufacturers. However, these are finite in their ability to integrate with an architectural lighting control system and often are limited to specific fixtures.
For this project, Cowart — like many homeowners building a home or those working with a designer — had already identified the fixtures he wanted to use. For that reason, it was paramount to find a dynamic and flexible lighting control system that could effortlessly program the color temperature and intensity that define an HCL experience and was compatible with the broadest range of tunable fixtures on the market today. Working with lighting design company Light Can Help You and residential integrator Atlanta Home Electronics, they identified Vantage LHUMAN integrated lighting solution as the best solution.
“Based on the lighting fixtures and the design, Vantage was really the only option we had to control everything that was already included,” said James Fenn, systems designer at Atlanta Home Electronics.
Solution: Vantage LHUMAN opens the door to immense lighting design freedom, simplicity of integration, and affordability for achieving tunable and human-centric lighting designs. Designers and homeowners can choose the tunable fixture they desire. In addition, using the solution’s tunable controllable profiles, the lighting system can achieve lighting scenes with precise color temperature, from fixture to fixture, for the task at hand — from productivity to relaxation or to replicating the natural lighting cycle indoors.
To achieve this, Atlanta Home Electronics used the LHUMAN Tunable Profile Library, which provides precise tunable profiles for the latest fixture makes and models from top lighting manufacturers within the Vantage Fixture Alliance. This partnership ensures LHUMAN offers true freedom of design, with designers able to choose from the widest selection of human-centric lighting and color-tunable fixtures available. Vantage has created profiles for leading fixture companies, including AiSPiRE, LF Illumination, ELEMENT fixtures from Tech Lighting, Environmental Lights, Lucifer, Proluxe by American Lighting, Circa Lighting, PureEdge Lighting, Colorbeam Lighting, and No. 8 Lighting.
From the library, installers simply select the chosen fixture(s) and Vantage’s Design Center programming software will automatically provide the defined fixture control details and color temperature mapping for the lighting fixture. This not only achieves super simple and fast programming but also allows Vantage’s control processor to provide the correct color mix, producing accurate color temperature and intensity for the lighting task selected. This innovation makes human-centric lighting possible using most fixtures; designers can mix and match fixtures in the room with the assurance that values will match from fixture to fixture for a cohesive room lighting design; and it supports 0-10V, DMX, and DALI control protocols. Freedom of design is also possible with Vantage’s selection of digital and button keypads, with faceplate options that can be mixed and matched to fit the home or the room aesthetic as well as control needs within the space.
Results: With Vantage LHUMAN, Atlanta Home Electronics simply dropped the preconfigured light profiles for the 100 lighting fixtures of various types (recessed, decorative, linear, etc.) around the Cowart home into the Design Center software, achieving a cohesive lighting effect across the space and executing Warfel’s lighting design as expected. The system made a substantial and time-consuming amount of complex labor effortless. On top of that, LHUMAN enabled HCL control, automating light shifting throughout the day with parameters set up across the house to achieve a natural lighting scene. For example, the homeowner’s customized scene for in the morning offers a low level glow in the kitchen for which to enjoy a cup of coffee — similar to the light experienced during a sunrise. In the family room, a sports scene was crafted that brings the lights down and turns on red accent lighting. The effect makes the room feel like a sports club. The movie scene dims the main fixtures but turns on lighting in the nearby kitchen and bathroom. Another special touch was sensor-activated lighting in the master closet.
There’s also outdoor lighting around the patio and pool. These lights come on at dusk. A nearby keypad provides at-a-touch operation of the patio’s recessed lighting, fan, and screens.
“One of the key challenges to doing lighting for wellness — lighting that mimics natural light — is making the color temperature and intensity of all the different fixtures look the same at a particular given moment of the day,” said David Warfel, lighting evangelist and founding lighting designer of Light Can Help You. “Whether those fixtures are from different manufacturers or even the same manufacturer, it can be a challenge. With Vantage, it was surprisingly easy to have that match.”
When it came to user interfaces, the homeowner chose a combination of Vantage’s digital keypad and four-button EasyTouch Glass keypads. The digital keypads were installed in high traffic areas where many more lighting scenes were needed, including the Kitchen, living room, breakfast nook, and front door entry. All the interfaces were outfitted with nickel faceplates for a cohesive look room to room.
“Throughout the installation and design of the system, I learned a lot more of what Vantage is capable of,” said Fenn. “The freedom of design — from all the options you have for the fixtures, layouts, and color spectrum to the variety of keypads — and the level of support, Vantage LHUMAN is definitely the lighting control system to use.”
“Between the fixtures, the design, and the integration of LHUMAN, the lighting enhances the look and feel of the space while marrying up with our lifestyle,” said Cowart.
