This document summarizes strategies for reducing energy consumption in facilities through newer technologies like LED lighting, cogeneration, and wireless automation systems. It discusses the cost and benefits of these technologies, where they can be applied, and available funding to assist with return on investment. The presentation covers LED lighting technologies and applications, different types of cogeneration systems from microturbines to gas turbines and their applications, and uses of wireless automation using technologies like Zigbee and EnOcean. It provides examples of calculating return on investment for these systems and discusses available rebates.

10. Gas Micro-Turbines
• Combine energy conservation/efficiencies with on site
production of electricity (co-generation)
• Local production and local consumption significantly
reduces transportation and distribution costs
• Installation of high efficiency gas microturbines to produce
on-site electricity and reduce GHG emissions
Absorbers
TriGeneration

11. CoGeneration >.3MW<5MW

12. Co-Gen 3MW +

13. Financial
