SB-12 Energy Star Training

  1. 1. Energy Efficiency TrainingSB-12 - Energy Star Design ® (Prescriptive Path)
  2. 2. IntroductionThis presentation provides the relevant information for inspecting or constructing anew home to the Energy Star® requirements using the prescriptive path.The presentation starts with the requirements of the Building Code for energyefficiency of new homes, called the Building Code Data. Then each of theelements listed in a Building Option Package (BOP) and the municipal EnergyEfficiency Design Summary submitted with the building permit application areidentified for review during construction. The elements consist of the requirementsfor Building Components, HVAC Equipment, Lighting Fixtures and Appliances -Detailed Building Specifications as listed in the Energy Star® for Homes TechnicalSpecification – Ontario.It is important to understand that the Building Option Package or BOP is a form thatthe certified energy advisor (CEA) completes based on the designers drawings fora new home. At the completion of construction this form will be signed by the CEAcertifying the home Energy Star® compliant and that a label maybe applied to theelectrical panel. Please note the Building Code does not require a physical label beapplied.
