ESCos charge a mark-up on project costs. Why should we pay these costs?
Good project management is essential for implementing any successful Energy Efficiency project (as indeed any project). Even if you try to manage a project using in-house resources, they do cost you money, either directly or indirectly. Unless you have an accounting system that will accumulate such costs and allocate them to your project, you may not realise the magnitude of costs incurred. What are these costs and how are they incurred? Some examples might help explain.
