Projected Market Impacts for the DALI Lighting Control Device Standard Development work are as follows.

A program to increase the standardization of DALI controls adds stable dimming and individual fixture control capability to the facility manager's energy tools. The first major energy impact is the reduction of demand and consumption in open office spaces. These spaces make up 65 percent of the lighting load in commercial office buildings. Providing individual fixture control linked to occupancy has been demonstrated to save an additional 30 percent over standard automatic off scheduling. Assuming California new office construction of 38 million square feet (10 percent of the US total), incorporating DALI individual fixture control in open spaces would result in a reduction in lighting demand of 9620 kW and a reduction in consumption of 28 million kWh.

In addition, demand throughout the office building can be reduced 30 percent in response to a power emergency without a major impact on occupants. Allowing occupants to control their own lighting has been shown to have a positive impact on occupant satisfaction and perception of task difficulty. These results are being confirmed through testing programs underway with PNNL's Light Right Consortium. DALI's 2-way communication and ability to centrally monitor energy usage and operation allows system performance to be verified and errors in operation identified and corrected.

The full impact of DALI will be reflected in the sales of digital, addressable dimming ballasts. Today dimming ballast make up an estimated 2 to 4 percent of the total ballast sales. This compares to 15 percent in Europe.
