Every energy audit is the same but different, the goal, searching for cost and energy savings is the same. whether its factory or office. And we follow the same published process, yet every energy audit guide attempts to detail how to identify those cost savings, and that is where the document evolves from its clinical, prescriptive list of requirements into vague generalizations because examining data, sometimes imperfect data, to find cost savings is more art than science.

Infra-red scanning tool is the latest high technology tool for surveying the condition of M&E services and buildings. the condition may appear normal to the naked eye, but infra-red imaging reveals subtle details not normally visible to humans and presents a false colour image for easy review.
