Energy Auditing
and
Energy Management Services
Energy Innovation Ltd. are the first choice for industry when it comes to Energy Auditing and Energy Management services.
Energy Innovation Ltd, are specialists in all aspects of industrial energy usage including the cost-effective performance of Energy audits.
We perform energy audits to a customer specification
.
The audit and survey is based on energy bills, metered consumptions, and on-site monitoring using the latest data-logging technology.
The following is a typical scope of work for an energy audit.
The scope is based on the recommended brief for a comprehensive energy audit and survey,
CIBSE AM5 1991 - Energy Audits and Surveys.

ENERGY AUDIT - TYPICAL SCOPE OF WORK
1.0 INTRODUCTION
A description of the site from an energy perspective, including functions and services.
2.0 EXECUTIVE SUMMARY OF SURVEY AND RECOMMENDATIONS
A brief summary of the report outlining potential energy savings identified by the audit and survey.
3.0 OBJECTIVES OF AUDIT AND SURVEY
Provide an audit of site energy usage.
Identify areas of potential energy cost savings
Provide an estimate of potential annual energy savings with order of magnitude costing (OMC) and payback analysis.
Identify how methods of energy management should be developed to achieve, maintain and recognise further potential savings.
4.0 ENERGY AUDIT REPORT
4.1 Site Information
Summary of information pertaining to energy use on the site.
