This case study is part two of a piggery audit conducted showing the electrical energy savings component. Implementation of new LED lights would allow an increase in capital for further efficiency measures and allow the installation of solar.
This case studies highlights the energy savings opportunities from audits at a number of pork farms. It highlights potential to reduce lighting energy by 66%, and reducing overall energy by up to 27% with the addition of Solar PV.
This case studies highlights the energy savings opportunities from audits at a number of pork farms. It highlights potential to reduce site heating energy by 20% with an average payback of 4.6 years.
The audits of several meat processors identified a payback of between 3.2 and 4.9 years of adding CO2 heat pumps to replace gas hot water systems. In one case a mixing valve was recommended to one system that was providing higher temperature to return a payback of 1.4 years. Additional benefits include greenhouse gas emission reductions of 283.5 t CO2-e.
The Audits of several meat processors identified the potential benefits of adding variable speed controls to evaporator fans with temperature control logic allowing the fans to operate at a lower speed with significant electricity savings. The audits have identified some quick wins to reduce costs of refrigeration systems at low cost.
