Prologis is a global provider of distribution facilities, with more than 600 million square feet of industrial space in North America, Europe, and Asia. The Prologis Commercial Building Partnerships energy upgrade project improved lighting efficiency at an 800,000-square-foot unconditioned warehouse leased by retailer Sears in Olive Branch, a town in northern Mississippi. The lights, which are on 24 hours a day, 7 days a week, represented the best opportunity for energy savings.
The National Renewable Energy Laboratory's lighting research group used lighting power density calculations to determine that a lighting retrofit alone would result in more than 30% energy savings compared to existing use and more then 51% savings compared to ASHRAE Standard 90.1. Actual savings compared to pre-retrofit utility bill analysis were just over 41%.

Discuss goals that were met and goals that were not achieved, and the reasons for these outcomes
Relatively simple light power density calculations showed the effectiveness of replacing traditional HID with T-12 fluorescent lamps.
It's an easy win-win situation when the owner and lessee agree to using Tenant Improvement money to improve lessee operating costs as well as tenant retention.
Many building leasing arrangements make it challenging to do even easy energy savings. Property owners need to reach out to tenants and share building and energy consumption information to the benefit of both.
Estimated payback time of any investment in measures needed to reach zero net energy
Estimated payback time for this project is 11 months.
A lighting upgrade to T-12 technology resulted in a more than 41% energy savings in annual electric energy use intensity.
Design for no more than 1.0 watts/square foot
Use high-efficacy T-5 fluorescent lamps
Use T-5 high-bay fixtures in high-ceiling areas
Use occupancy sensors
