LEDs comes out as one of the most attractive energy efficiency upgrade financial returns yet again in the Energy in Buildings 50 Best Practice Initiatives by Norman Disney Young.

The Clean Energy Finance Corporation (CEFC) commissioned Energy in Buildings: 50 Best Practice Initiatives as a practical, user-friendly resource for property owners and managers. Of the 50 initiatives described in this handbook, many can have relatively short-term paybacks. For the right market sector and climate zone, 16 of the initiatives could typically pay back inside 5 years, and 36 of them within 10 years. Many of those 36 initiatives are also relatively affordable: about one third, in a new-build scenario, would require an additional cost less than 0.1% of overall asset value. Most are also appropriate for existing buildings, depending on the scope of the retrofit.
