Energy and water surveys and audits
Energy surveys and audits are used primarily to discover opportunities to maximise underlying efficiency through investment in alterations and improvements. Surveys and audits usually relate back to performance benchmarks and norms. For full effect, however, they should also draw on information gathered during performance monitoring.

It is also helpful if you can maintain a database (in the loosest sense) of product information including not just trade literature but also independent editorial, lists of reference customers, and cost data.
