Lighting : February 2014 Lighting (v2-HR)
44 LIGHTING MAGAZINE | February/March 2014 February/March 2014 | LIGHTING MAGAZINE 45 performanceinlighting.com NEW ERA ERA is a unibody luminaire bollard for general and accent outdoor lighting. Its raw character adapts well to nature’s variety of surfaces with an organic design entirely integrating the advantages of LED. The new face of lighting has arrived. For these reasons our first goal is to define the criteria by which the project will be measured to ensure that it will be successful. The first thing that we do is get the client to consider a number of questions and provide responses: l What is an acceptable simple payback period? l How much energy reduction do we expect? l How much maintenance are we prepared to provide? l How much improvement does our lighting need? l How much funding already exists for replacement of equipment at end of life? l Which procurement model best suits our company? Once these targets have been met we can look at their current system and its baseline costs. The workshops we provide for OEH and much of our other work revolves around the outcomes of the review of energy efficient lighting outlined in the technology report published by OEH or the principles of comparison established by the report. Using the OEH Calculight tool we can establish the cost of ownership of the existing system and compare these costs with those of a variety of solutions as shown in the following example. The importance of using Calculight is that it provides a level playing field for comparing total cost of ownership. Our sample building contains an open plan office with 20 recessed troffers containing magnetic control gear and two 36 Watt tubes outlined in these courses and our work in the private sector is as follows: 1. Establish the expectations and requirements of the client for their project. 2. Provide training on the basics of light and lighting. 3. Establish the characteristics of the existing system and its pros and cons. 4. Establish the total cost of ownership of the existing system utilising data collected from site and the output from Calculight. 5. Use Calculight compare total cost of ownership of pre-qualified options and to produce general specifications. Calculight can be used to enter data about other options considered appropriate as replacements. 6. Collate the collected data into a briefing document that can be used to obtain offers from lighting suppliers. 7. Go to market to obtain solutions from suppliers. These solutions should include provision of lighting designs demonstrating standards compliance for the identified project. 8. Use Calculight to confirm and compare the total cost of ownership of the offers. 9. Select the solutions, utilising external specialist advice to check standards compliance if required. Implementing the upgrade. 10. Evaluate the project and ensure that original project requirements have been met. ESTABLISHING THE NEEDS OF THE PROJECT We have worked to provide solutions in the area of energy efficiency for a very long time. An early lesson learned was that there is often little maturity in the structure of policy within companies on the requirements of energy efficient solutions. Many projects were worked on, in great detail, only to be vetoed at the end because: l they were outside of a previously undisclosed simple payback expectation; l or a capital expenditure limit; l or a lease term that is significantly shorter that the simple payback period; l or the CEO does not believe in climate change and therefore anything related to energy efficiency is not considered (even if the simple economics make sense); l Etc. The basic output page looks like this: Using the OEH Calculight tool we can establish the cost of ownership of the existing system and compare these costs with those of a variety of solutions ....
