4 2012 OBC CodeNews Issue 210 The New 2012 Building Code Ontario has released a new Building Code. On November 2, 2012, Ontario Regulation 332/12 was filed to introduce the new Building Code. Most of the new Building Code will come into force on Jan. 1, However, certain requirements will come into force later on Jan. 1, 2015 and Jan. 1, The new Building Code substantially bt till improves energyefficiency requirements and makes Ontario one of the leading jurisdictions in North America for water conservation. Ontario Regulation 332/12 is available on Service Ontario s e Laws website. 4

37 STEP 2 IDENTIFY THE MAJOR OCCUPANCY(IES) ON EACH FLOOR IN / OF THE BUILDING 2-37

38 DEFINITION OF MAJOR OCCUPANCY Major occupancy means the principal i occupancy for which a building or part thereof is used or intended to be used, and shall hllbe deemed dto include the subsidiary bidi occupancies which are an integral part of the principal occupancy

39 KEY FACTORS IN DEFINITION OF MAJOR OCCUPANCY : PRINCIPAL OCCUPANCY WHAT IS THE MAIN OCCUPANCY IN THE BUILDING? WHAT IS THE REAL FUNCTION OF THIS BUILDING? MAJOR OCCUPANCY INCLUDES SUBSIDIARY OCCUPANCIES WHICH ARE AN INTEGRAL PART OF THE PRINCIPAL OCCUPANCY EXAMPLES: POOL IN A HOTEL CONFERENCE ROOM IN AN OFFICE TENANCY / OWNERSHIP / RIGHTS OF USAGE MAY BE AN ISSUE 2-39

40 WHY? PART 3 or 9 CONSTRUCTION REQUIREMENTS MATERIALS FIRE RESISTANCE RATINGS MAJOR OCCUPANCY FIRE SEPARATIONS SPATIAL SEPARATION REQUIREMENTS PUBLIC CORRIDOR FIRE SEPARATIONS CLASSIFICATION AS A HIGH BUILDING TRAVEL DISTANCE 2-40

42 OAA DATA MATRIX 2-42

43 STEP 3 DETERMINE THE BUILDING AREA DEFINITION OF BUILDING AREA : Building area means the greatest horizontal area of a building above gradewithin the outside surface of exterior walls or within the outside surface of exterior wallsand and the centre lineoffirewalls firewalls. BUILDING AREA AFFECTS: CONSTRUCTION REQUIREMENTS

44 BUILDING AREA GREATEST HORIZONTAL AREA OF A BUILDING ABOVE GRADE WITHIN OUTSIDE SURFACE OF EXTERIOR WALLS WITHIN OUTSIDE SURFACE OF EXTERIOR WALLS AND CENTRE LINE OF FIREWALL 2-44

45 BUILDING AREA IS NOT: GROSS AREA LEASABLE AREA NET AREA FLOOR AREA MAY NOT BE THE GROUND FLOOR AREA! 2-45

49 STEP 4: DETERMINE BUILDING HEIGHT NUMBER OF STOREYS A HEIGHT IN METERS TO TOP FLOOR TO TOP CEILING / ROOF USED IN DETERMINING CONSTRUCTION REQUIREMENTS IF IT IS A HIGH BUILDING (3.2.6) 2-49

50 BUILDING HEIGHT NEEDS GRADE Grade means the average level of proposed or finished ground adjoining a building at all exterior walls. FIRST STOREY FLOOR CLOSEST TO GRADE WITH CEILING MORE THAN 1.8 M ABOVE GRADE TWO CONDITIONS: FLOOR CLOSEST TO GRADE, AND CEILING MORE THAN 1.8 M ABOVE GRADE 2-50

51 BUILDING HEIGHT 2-51

52 STEP 5: NUMBER OF STREETS HOW MANY STREETS DOES YOUR BUILDING FACE? FOR THIS OBC REQUIREMENT, STREETS MUST MEET SPECIFIC REQUIREMENTS EVERY BUILDING IS REQUIRED TO FACE A STREET WHICH MEETS AND (1) 2-52

53 WHAT CREATES A STREET FOR OBC PURPOSES AN ACCESS ROUTE WHICH MEETS (2) NOT PERMITTED TO BE A STREET: TUNNELS BRIDGES ENCLOSED SPACES (EVEN IF USED FOR VEHICULAR OR PEDESTRIAN TRAFFIC (5) 2-53

54 NUMBER OF STREETS AFFECTS: CONSTRUCTION REQUIREMENTS MORE IMPORTANT FOR NON SPRINKLERED PROJECTS AS LARGER BUILDING AREAS PERMITTED WHEN MULTIPLE STREETS 2-54

55 HOW MANY STREETS DEPENDS ON PERCENTAGEOF BUILDING PERIMETER ADJACENT TO A STREET 1 STREET: NO PERCENTAGE SPECIFIED 2 STREETS: 50% OF THE PERIMETER 3 STREETS: 75% OF THE PERIMETER 4 STREETS: NOT RECOGNIZED

56 WHAT ARE ACCESS ROUTE REQUIREMENTS IN 325? 3.2.5? MINIMUM WIDTH: 6 M MINIMUM DISTANCE FROM BUILDING FACE: 3 M TO NEAR CURB EDGE MAXIMUM DISTANCE FROM BUILDING FACE: 15 M TO NEAR CURB EDGE MAXIMUM GRADIENT: 1 IN 12.5 OVER 15 M MINIMUM CENTRELINE RADIUS: 12 M MINIMUM OVERHEAD CLEARANCE: 5 M

116 FIREWALL DEFINITION Firewall means a type of fire separation of noncombustible construction which subdivides a building or separates adjoining buildings to resist the spread of fire and which hhas a fire resistance it rating as prescribed in this Code and has structural stability to remain intactunder fire conditions for the required fire rated time. KEY POINTS SUBDIVIDES A BUILDING SEPARATES ADJOINING BUILDINGS STRUCTURAL STABILITY 2-116

117 WHAT IS A FIREWALL? A VERY SPECIFIC TYPE OF FIRE SEPARATION MUST GET ITS FIRE RESISTANCE RATING FROM CONCRETE OR MASONRY FIREWALL NOW PERMITTED TO BE OF DRYWALL AND STEEL STUD NEW PERMISSIONS FOR 2 H WALLS IN 2006 OBC STRUCTURALLY INDEPENDENT IF CONSTRUCTED AS A SINGLE WALL CONNECTED TO A CONCRETE STRUCTURE IF 2 WALLS ARE USED IS REQUIRED TO EXTEND ABOVE THE ROOF FORM A PARAPET COMBUSTIBLE MATERIAL CANNOT EXTEND ACROSS A FIREWALL 2-117
