The document discusses the importance of comprehensive energy efficiency projects over smaller, individual measures. It argues that integrated projects targeting areas like HVAC, controls, daylighting and fenestration can achieve 15% energy savings and 15% operational cost savings, with returns over 4%. In comparison, changing light bulbs alone may only achieve 10% energy savings with lower returns. The document advocates for performance monitoring to identify issues early and protect investments.

Editor's Notes
- #4: According to the USGBC, buildings consume 72% of US electricity,14% of all potable water, and generate 38% of CO2 emissions.
- #5: According to the EIA, the DOE guys who collate all the actual stat’s, 70% of all fossil fuels are wasted before you even get a chance to use them.

- #16: Edit to show no longer sending money down the utility drain.
