Lighting controls, including Watt Stopper/Legrand’s Miro controls and residential occupancy and vacancy sensors, played an important role in the successful completion of the project. Ladendorf moved into his home in December 2007 and Mellon says, “Every time I see Nathaniel come into his house and touch just one switch to light up his safe haven, I experience great peace of mind.”
Energy code and design considerations
California Title 24 allows only limited use of incandescent lighting in residential applications, but gives designers more leeway in selecting sources if the lighting will be controlled by vacancy sensors or, in some locations, by dimmers. Mellon learned about Watt Stopper/Legrand’s control options at an ASID seminar on Title 24 requirements and was pleased to find out that she did not need to sacrifice any of her design standards to achieve energy efficiency.
By using Miro dimmers in the living area and bedrooms, and vacancy sensors in the bathrooms, she was permitted to use decorative and flattering lighting including low voltage track lighting and incandescent bath bars. Additionally, since Miro Universal Dimmers are designed to dim incandescent, magnetic or electronic low voltage and dimmable fluorescent loads, she could specify the same dimmer type for all applications, simplifying the design and installation.
Miro’s Architectural styling also helped Mellon achieve her design goals. She selected warm white devices for their pleasing look on the walls and used matching Miro Wiring Devices throughout the home.
Mellon took advantage of Miro’s wireless control capabilities to create two layers of scene control and facilitate control of selected lighting from outside the home for safety and convenience. Ladendorf caries a Key Fob controller to turn lighting scenes on from his car when arriving home. He typically illuminates a pathway from the garage to the living room area.
Once inside, he can use wall mounted House and Room Scene Controllers to select a variety of lighting looks for either the whole house, including activating a pathway from the living area to the master bedroom, or just for the living area. Additionally, a handheld House Scene Remote, carried in his wheelchair, provides access to lighting scenes from any location.
The scene controllers send RF signals to the wireless Miro dimmers and to wireless Miro switches that were used for non-dimmable loads. Scene memory is stored in each power device, and controllers can activate any number of dimmers and switches.
For additional security, a Watt Stopper occupancy sensor automatically activates garage lighting when motion is detected. Inside the home, vacancy sensors allow bathroom lighting to be turned on manually when needed. The vacancy sensors include LED nightlights that provide low level illumination when the lights are off. All of the sensors ensure energy savings by automatically turning lighting off when no occupancy has been detected following a time delay.
The 1,700- square-foot home was gutted, and the floor plan changed from the original four bedroom, two bath to a three-bedroom design that is barrier free and easily accessible from exterior to interior.
The 40-year-old wiring was replaced for safety and to meet current building code requirements, but controls had not yet been specified when the wiring was completed. Fortunately, since the wireless Miro controls communicate using an RF protocol, no control wiring was needed. Installing Miro did not cost any more than installing standard dimmers or switches.
Following installation, Watt Stopper’s support team provided advice and assistance programming the scene controls, and the system is operating as expected.
Living in the new home
After six months in his new home, Ladendorf is settled in and comfortable. “Nathaniel is very happy with the look of the controls and the simplicity of using his lighting system,” Mellon notes. She concludes, “This project has forever changed my approach to design. All future jobs will benefit from this journey.”
