On farm energy use represents about 62% of an egg operation’s on-farm climate change impact in Alberta.  In an effort to investigate and communicate technology options for reducing this impact, EFA and Alberta Agriculture and Forestry (AF) partnered with Brant Colony, to design and construct an egg laying facility that would come as close as possible to balancing energy generation and consumption (ie: net-0).  Thanks to funding from Growing Forward 2, in addition to other energy conservation and generation technologies, the facility was able to make several upgrades to their egg cooler:

  • use of an Electronically Commutated Motor (ECM) on the evaporator coil and condenser coil fans
  • designated cold storage overhead doors with improved insulation

In addition, the barn was equipped with energy submeters to capture detailed data on areas of energy consumption in the layer barn.  Data collected with respect to the cooler includes:

  • compressor motor load
  • condenser fan load
  • evaporator fan load

In order to compare this data against benchmark coolers of a similar size, and better communicate the cost-benefit of these technologies to other egg farmers, EFA and AF worked with WestCan Solar and EnSave to install submeters in four other egg barns in Alberta.  As a result of the data and analysis, the following information bulletins were developed and posted to EFA’s producer website, under Best Production Practices / Environment:
