There are 42,240 total lamps used for interior lighting within the Utah State Capitol of those 3,403 or only 8% are incandescent lamps. All other lamps 38,837 or 92% are energy-efficient lamps consisting of fluorescent, HID and LED.
The total interior Lighting Power Density is 0.98 watts/sf.
The allowable Lighting Power Density by code (ASHRAE 90.1-1999 or 2001) is 1.3 watts/sf.
This results in an improvement of 25% over and above the code requirement.

Energy Conservation and the Renovated State Capitol
During the design of the Utah State Capitol Restoration architects and engineers working with the executive director sought to incorporate energy saving elements into the restoration work. These elements have successfully reduced the energy consumption of Capitol Hill from what it was in 1999 to what it is today. Some of the elements that have been incorporated in the capitol include the following list:
· Lighting-96% LEED (Leadership in Energy in Environmental Design) certified
· Windows-replaced the windows to make them more thermal for energy efficiency
· Central Plant-completely new and energy efficient
· Underground Parking-reduced heat
· Roof-Light Color, reflects heat
· Day Lighting-skylights and low lights, more natural light throughout the building
· Water Sensor's in Landscaping-to make sure we don't over water
· Weather Station-to help us understand how much we need to water
· Drip Irrigation System-mainly for the trees, in case of a drought to be able to water the trees only
· Concrete usage around the Capitol instead of asphalt-reducing heat
· Out door lighting-lights that have "cut-off" tops so we don't leak light
· Occupancy Sensors in Offices
· Exhibit Cases-Renewable lyptus wood
· Mechanically Pre Cooling the building using three different types of cooling procedures, free cooling (completely outside air) evaporative (kind of like swamp cooler effect) and regular air conditioning. These three helps reduce the overall energy.
· Electrically-low energy light bulbs
· Appliances-All Energy Star products
· Reduced carbon footprint by retaining embedded energy. I.e. granite, marble, chamber's marble etc...
