  1. Dairy Energy Calculators Calculating Energy use and Energy Conservation Measure Savings Northeast Agriculture Technology Corporation

  2. Vacuum Pumps • Calculating Vacuum Pump Capacity • Vac Pump Capacity (cfm) = • base cfm + 2.0 cfm/milking unit + • 1.2 cfm/milking unit safety factor • base cfm = 35 Northeast Agriculture Technology Corporation

  3. Vacuum Pump Horsepower • Calculating Horsepower requirement for a vacuum system vac. pump Hp. = vac. pump capacity (cfm) 10 cfm/Hp Northeast Agriculture Technology Corporation

  4. Energy Savings of an ASDon a Vacuum Pump • Savings calculator for a vacuum pump ASD Annual savings (kWh) = [Hp of vac pump – (0.25 x no. of milking units)] x (0.9 x hrs of operation/day x 365 days/yr Northeast Agriculture Technology Corporation

  5. Milk Pre-Cooler • Calculator to determine savings of well water pre-coolers • Annual savings (kWh/yr) = • 0.3 kWh saved/cwt of milk x cwt of milk cooled/yr Northeast Agriculture Technology Corporation

  6. Savings of a Precooler with an ASD on the Milk Pump • Estimated annual energy savings using a well water precooler with an ASD on the milk pump Annual savings (kWh/yr) = 0.45 kWh saved/cwt of milk cooled x cwt of milk cooled/yr Northeast Agriculture Technology Corporation

  7. Lighting Calculators • Calculating required lamp watts Lamp watts required = required lumens/sq ft coefficient of util. X watts x sq ft of lighted area X rated lamp lumens 1.20 light degradation factor x 1.13 ballast factor Northeast Agriculture Technology Corporation

  8. Lighting Calculators • Calculator to determine how many light fixtures are required: No. of light fixtures = lamp watts required watts/fixture Northeast Agriculture Technology Corporation

  9. Livestock Fountains • Calculator to determine annual energy use by a heated livestock fountain: 1) Inside a shelter Annual kWh = 3.5 kWh/cow/yr 2) Outside Annual kWh = 5 kWh/cow/yr Northeast Agriculture Technology Corporation

  10. High Efficiency Ventilation fan Energy Savings • Calculator to determine savings from installing higher efficiency fan: Hi efficiency fan savings (kWh/yr) = Total cfm old _ total cfm new x 1 kW cfm/watt old cfm/watt new 1000 watts X hours fans operate/year Northeast Agriculture Technology Corporation
