Energy Profile
Energy Profile
| Developing an energy profile for a building is the best place to start when looking to implement an effective energy management strategy. A good energy profile will tell you: |
|
| This information will not only provide a benchmark to compare the future success of energy saving initiatives it will also allow you to compare your facility against other facilities. More importantly it will point out any consumption anomalies that can be remedied to reduce wasted energy. An important part of the Energy Profile is the NABERS Assessment where this is appropriate. This will collect all the information required for a NABERS Rating and identify any operational, data or metering issues that would need to be resolved before a formal NABERS Rating could be issued. |
Case Study - Energy Profile |
| We undertook an energy profile for a customer in Melbourne and discovered that the newly installed Variable Speed Drives (VSD’s) on the cooling tower fans had an incorrect control strategy. The VSD’s were not correctly programmed to provide continuous modulation of the fan motors causing large fluctuations in chilled water temperature which in turn adversely impacted the performance of the chillers. As the chillers are the largest users of energy in the building, the system was not seeing the maximum benefit of the VSD installation. |
