If you are doing any new construction or additions to an existing structure within the shoreline activity area, you will require a Development Permit; 2. A Township of Lake of Bays building permit application fully completed including Roll No.; 3. You will be required to submit the following plans: o Site plan showing all structures, proposed structures, wells, and septic system, with dimensions and setbacks; o Building plans (2 sets of each) including o Floor plans o Cross sections (including air barrier location and details) o Elevations o Truss plans o Engineered floor systems o Plumbing o Heating systems, duct work plans(including Heat loss calculations) o Electrical drawings o Any engineered documents o Samples of the above are available at the Township office or on our web page at under Building Department. 4. Ensure that the Schedule 1 Designer sheet is completed by each individual who has completed any of the above noted designs, ie) plumbing, heating, floor plans, etc. 5. Permit fees; 6. A completed septic calculation sheet, if applicable. The performance level of a septic system must be evaluated if one or more of the following are proposed; 1. Adding bedrooms, 2. Adding fixtures, or 3. Increasing floor area by 15% or greater. The daily design flow of the septic system must meet Division B of the Ontario Building Code. AND 7.

Completed Energy Efficiency Design Summary The Building Department can only accept and review complete applications and plans. The review is to ensure that they meet Ontario Building Codes, Municipal by-laws and other applicable law. If the project requires a septic approval, the building permit will not be issued until such approval is granted.

8 Guide to the Energy Efficiency Design Summary Form The Energy Efficiency Design Summary form summarizes the compliance path used by a house designer to comply with energy efficiency requirements of the Ontario Building Code. This form is completed by the person responsible for the energy efficiency design of the project, and must be submitted with the building permit application. The information on this form MUST reflect the drawings and specifications being submitted, or the building permit will be refused. Refer to Supplementary Standard SB-12 for details about building code compliance requirements. Further information about energy efficiency requirements for new buildings is available from the provincial building code website at or the municipal building department. Beginning January 1, 2012, a house designer must use one of four energy efficiency compliance options in the building code: 1. Comply with the SB-12 Prescriptive design tables, 2. Use the SB-12 Performance compliance method, and model the design against the prescriptive standards, 3. Design to Energy Star standards, or 4. Evaluate the design according to EnerGuide technical procedures and achieve a rating of 80 or more. COMPLETING THE FORM B. Compliance Options Indicate the compliance option being used. SB-12 Prescriptive requires that the building conforms to a package of thermal insulation, window and mechanical system efficiency requirements set out in Subsection of SB-12. Energy efficiency design modeling and testing of the building is not required under this option. SB-12 Performance refers to the alternative method of compliance set out in Subsection of SB-12. Using this approach the designer must use recognized energy simulation software (HOT2000 V9.34c1.2 or newer), and submit documents which show that the annual energy use of the building is equal to a prescriptive package. Energy Star houses must be designed to Energy Star requirements and be labelled on completion by Enerquality or other agency. The Energy Star BOP form must be submitted with the permit documents. EnerGuide80 houses are validated by NRCan authorized energy advisors and must achieve a rating of 80 or more when evaluated in accordance with EnerGuide administrative and technical procedures. C. Project Design Conditions Climatic Zone: The number of degree days for Ontario cities is contained in Supplementary Standard SB-1 Windows, Skylights and Glass Doors: If the ratio of the total gross area of windows, sidelights, skylights and glass doors to the total gross area of walls is more than 17%, higher efficiency glazing is required. If the ratio is more than 22% the SB-12 Prescriptive option may not be used. The total area is the sum of all the structural rough openings. Some exceptions apply. Refer to of SB-12 for further details. Fuel Source and Heating Equipment Efficiency: The fuel source and efficiency of the proposed heating equipment must be specified in order to determine which SB-12 Prescriptive compliance package table applies. Other Building Conditions: These construction conditions affect SB-12 Prescriptive compliance requirements. D. Building Specifications Thermal Insulation: Indicate the RSI or R-value being proposed where they apply to the house design. Under the SB-12 Prescriptive option, RSI 3.52 wall insulation is permitted in certain conditions where other design elements meet higher standards. Refer to SB-12 for further details. E. Performance Design Summary This section is not required to be completed if the SB-12 Prescriptive option is being used. AIRTIGHTNESS REQUIREMENTS FOR NEW HOUSES All houses must comply with increased air barrier requirements in the building code. Notice of air barrier completion must be provided and an inspection conducted prior to it being covered. A blower door test to verify the air tightness of the house must be conducted during construction if the NRCan EnerGuide80 option is used, or if the SB-12 Performance or Energy Star options are used and an air tightness of less than Pa in the case of detached houses, or Pa in the case of attached houses is necessary to meet the required energy efficiency standard. ENERGY EFFICIENCY LABELING FOR NEW HOUSES Energy Star and EnerGuide issue labels for new homes constructed under their energy efficiency programs. The building code does not regulate new home labelling.
