Continuing from our previous blog, this discussion looks at optimising power factor on site and how it can reduce your electricity costs. Put simply, Power Factor (PF) is a measure of how effectively buildings are using their electricity.  Like a car out of tune, a poor PF will add to your electricity cost and waste energy. PF optimisation equipment usually pays for itself in less than two years.  By installing the equipment, you will receive a reduction in the peak demand portion of your electricity account.  The equipment is usually installed next to the main switchboard.  Improving PF from  0.7 […]

Continuing from our previous blog, a diverse “multi-path” approach is required for energy management to reduce energy, greenhouse gas emissions and operating costs.  Two of the paths previously suggested include measuring energy efficiency between diverse premises (benchmarking) and the five-steps to successful energy management.  This discussion and the next blog look at building load duration plots or building power signatures and benchmarking to help in reducing energy costs.  Remember “What gets measured, gets done”.  Load Duration Plot or Building Power Signature Electricity annual consumption patterns or ‘signatures’ for premises and buildings may be useful in comparing performance between time periods and […]

Further to our previous blog, a diverse “multi-path” approach is required for energy management to reduce energy, greenhouse gas emissions and operating costs.  Two of the paths previously suggested include comparing energy efficiency between diverse premises (building power signatures) and the five-steps to successful energy management.  This discussion continues with power bench marking  to help in reducing energy costs.  Remember “What gets measured, gets done”. Load Factor (LF): Is a measure or indication of the extent to which the electricity supply is fully utilised i.e. the higher the better, up to 100%.  It is a measure of the volatility in […]

Continuing from our previous blog, this discussion looks at Measurement and Verification (M&V) plans.  Energy and water use remain a controllable cost and energy or water users can make significant savings through a systematic approach to the management of energy or water.  One of the steps to energy or water management is to report and measure progress, which includes M&V. M&V is the process of using measurements to reliably determine actual saving created within a facility or building.  Some of the key points of M&V is outlined in the International Performance Measurement & Verification Protocol (IPMVP).  The IPMVP is prepared […]
