The United Nations ICLEI Triple Bottom Line standard for full cost accounting quantifies three levels of benefits of investing in lighting upgrades.

Economic/Profit – Energy savings; Facilities Management
Environmental/Planet – Carbon benefits (related to electricity); Water (related to electricity); SOx/NOx Outdoor Air Quality benefits
Equity/People – Task performance; Health; Satisfaction

In our EEBHub Research, the NPV calculations are successive, based on a 15 year time frame, 10% discount rate, and average costs for lighting upgrades in existing medium sized office buildings.
