100% of the light fixtures, lighted vanities, bulbs and ceiling fans selected for interior and exterior use in this project have an Energy Star Label or qualified equivalent energy consumption (through use of LED light fixtures and bulbs). This exceeds code requirements as well as the requirements of the Energy Star Advanced Lighting Package (ALP), which is 60% Energy Star qualified hard-wired fixtures and 100% qualified fans. Additionally, other benefits are:
A. The projected life of the LED bulbs is 50,000 hours to 60% lumen maintenance compared to 7,000 hours for CFL bulbs.
B. Total wattage and thus energy consumption is less for the LED fixtures in this project than comparable fluorescent fixtures (see attached spread sheet).
C. LED bulb components contain no toxic materials and are more easily recycled than CFL bulbs.
D. Reduction in installed wattage reduces cost of installed electrical infrastructure (service size, panel size, number of circuits, wiring size, control devices).
E. LED bulbs and fixtures provide more manageable tools for lighting applications. For example, the Cree XRE par 30 bulb is available with controlled beam spreads of 15, 25, 40, 60, 80 and 120 degrees providing more control and thus, in this application, fewer fixtures required to achieve lighting goals.
A similar code compliant house using conventional incandescent fixtures can expect annual lighting costs of $1,479. Rainshine’s lighting system projects annual lighting costs of $295. The spreadsheet below demonstrates the savings.
