  3. 3. What is a building simulation?A building simulation is amathematical model developedusing standard software thatreproduces actual buildingconstruction and equipment details.In providing an exact reproduction ofa building‟s design, a simulationdemonstrates patterns of energyconsumption by end use (heating,cooling, and equipment), compares Building Code, Model Nationalthe building to standard building Building Code, ASHRAE or anycodes, and predicts how a building other local code and is used in thewill perform under different design and construction of new orconditions. retrofitted buildings.A building simulation will identify if abuilding has complied with standardbuilding codes, such as the Ontario
  4. 4. Regulations in the industryOntario Building Code † Energy Code for Buildings .

The Code applies to new construction or additions, but not to alterations or renovations of existing buildings (unless they are so extensive that they amount to new construction).
  5. 5. Managing challenges  Developing common goals andToday, many organizations face objectives for the developmentmultiple challenges when constructing or retrofit.or retrofitting buildings in Ontario.  Reviewing all energy efficiencyExample of these challenges are: scenarios prior to capital spending. Ensuring buildings are built or retrofitted according to the Ontario  Evaluating all energy incentive Building Code. opportunities prior to commencement of project. Managing all aspects (architects, mechanical and electrical engineers) of the building‟s design. To overcome these challenges complete an assessment of the building‟s design. This assessment will identify consumption patterns, compare building metrics to industry code and help manage the design team‟s objectives.

  7. 7. There are variousenergy incentiveprograms availableacross Ontario tohelp offset the costsof designing anenergy efficientbuilding.
  8. 8. Types of energy incentives in OntarioThere are three major providers of incentives for building designs. Thefollowing pages will describe each program, its requirements, incentivevalue and benefits.1. Enbridge − Design Advisory Program − New Building Construction Program − Business Partner Implementation Support3. Ontario Power Authority − High Performance New Construction ProgramNote: City of Toronto - Better Buildings Partnership (BBP) assists buildingowners and developers access Ontario Power Authority‟s HighPerformance New Construction (HPNC) program.
  9. 9. EnbridgeDesign Advisory ProgramEncourages design activities aimed at improving a building‟s energy andenvironmental performance whether it is a new building, an addition to an existingbuilding or a major renovation.Requirements Incentive BenefitsThe DAP incentive must be used to develop a building simulation Fixed $3000 • Quantify benefits andmodel supporting a variety of activities that can lead to better, more costs of alternativeenergy efficient buildings: designs • Find the most cost-• Employing an Enbridge pre-approved DAP adviser to assist in effective design the design process solutions.• Developing energy simulation models using EE4, Equest or • Understand the DOE-2 software relationship between• Undertaking an environmental performance assessment using building systems. either LEED™ or Green Globes™ • Establish correct• Examining and evaluating design alternatives to improve equipment sizing to energy and/or environmental performance reduce capital costs• Following an integrated design process • Achieve ongoing energy savingsTo qualify for DAP incentive a project must be: without sacrificing• A new structure; OR other performance• A new addition to an existing structure; OR objectives• A renovation that upgrades the structure to meet MNECB • Improve building Mandatory Provisions environmental• The project must conform to Part 3 of the Ontario Building performance and Code (OBC) 2006 and be intended for commercial, institutional comfort or multi-unit residential occupancy • Enhance your building‟sProject must be located within the Enbridge Gas Distribution marketabilityfranchise territory

Projects with simplepaybacks of up to 8 years typically have positive TRC
  11. 11. EnbridgeBusiness Partner Implementation SupportThis incentive is designed to help support design decision makers in encouragingbuilding owners to implement energy efficient design. It is intended to help offsetthe administrative cost of assessing and reporting the energy efficient designalternatives included a new building.Requirements Incentive BenefitsOnly eligible if your are applying for the New Building Fixed Helps offsets the costsConstruction Program. $2000 of hiring a professional design teamRecipient of incentive (business partner) is identified on theNBCP application.Only paid when the NBCP Request for Payment is completedand accepted by Enbridge.Enbridge pre-approval required
