2 2011 National Energy Code Part 1: relax

3 National Energy Code for Buildings

4 National Energy Code for Buildings (maybe) it ain t no big thing

9 National Energy Code for Buildings is about building a better cow

10 National Energy Code for Buildings is NOT about innovation (this is a good thing)

11 NECB uses conventional building systems in its format; Part 1&2: general administration Part 3: envelope Part 4: lighting Part 5: HVAC Part 6: service water Part 7: electrical power systems Part 8: performance compliance modeling

12 NECB uses conventional building systems in its format; Part 1&2: general administration A Part 3: envelope Part 4: lighting S Part 5: HVAC Part 6: service water M Part 7: electrical power systems Part 8: performance compliance modeling E

13 NECB uses conventional building systems in its format; Part 1&2: general administration Part 3: envelope Part 4: lighting Part 5: HVAC Part 6: service water Part 7: electrical power systems Part 8: performance compliance modeling

14 NECB is applicable to; ALL new buildings Group A, B, and F1 ALL new buildings greater than 600m² or exceeding 3 storeys Group C, D, E, F2, and F3 Additions Section 9.36? Yup

15 NECB is applicable to; an aside NECB is a separate document from ABC 9.36: different applications, scope, timelines, requirements, tools Scope NECB: envelope, lighting, HVAC, service water, electrical distribution & motors ABC 9.36: envelope, HVAC, service water

16 NECB is applicable to; an aside NECB is a separate document from ABC 9.36 NECB: almost always requires professionals ABC 9.36: rarely requires professionals unless performance modeling ABC

17 NECB is a designer s code; NECB has multiple compliance paths; Prescriptive (do this. don t do that) Trade-off (I can t do that, so I will do this) Performance Compliance Modeling (can t do this or that; computer lets me do these) REMEMBER THIS WHEN WE TALK ABOUT PERMITS

18 NECB is a designer s code; NECB A

19 Part 3: Building Envelope Points of note; ALL assemblies are Effective Thermal Resistance NECB 2011 User s Guide ASHRAE Fundamentals THIS MATTERS NOW

20 Part 3: Building Envelope (cont.) Points of note; prescriptive values vary with climate zone NECB NECB NECB

21 Part 3: Building Envelope (cont.) Points of note; FDWR (Fenestration and Door to Wall Ratio) is limited FDWR is calculated dependent on climate FDWR ( HDD) 3000

22 Part 3: Building Envelope (cont.) Points of note; FDWR (Fenestration and Door to Wall Ratio) is limited FDWR is calculated dependent on climate FDWR ( HDD) 3000

23 Part 3: Building Envelope (cont.) Points of note; Includes interior spaces if ΔT greater than 10 ⁰C 2 trade-off paths; simple & detailed (these will be your friend ) Simple Trade-off: hand calculations, like for like Detailed Trade-off: computer model, anything for anything Watch out for: spandrel panels, overhead doors, slab bands/balconies, trade-off limitations

24 Part 4: Lighting Points of note; Accounts for installed lights, ballasts, transformers, and controls including exterior lights Calculations may be done by either Building Area or Space-by- Space methodologies (talk to your engineer ) Automatic light controls required in most spaces, some daylighting controls Watch out for: calculations, energy trade-offs, lumens vs. watts

25 Part 5: Heating, Ventilation & Air Cond. Points of note; Covers sizing, installation, and equipment Duct leakage is included Pumping, piping, and controls oh my! Lots of minimum equipment efficiency standards Watch out for: trade-off calculations a little bit tricky, lots of tabled data to sort through

26 Part 6: Service Water Heating Points of note; Covers efficiency, installation, and controls Trade-off calculations look more onerous than they really are Combination heating / service water also covered Watch out for: probably the simplest chapter, largely an equipment, insulation and sizing check

27 Part 7: Electrical Power Systems & Motors Points of note; Monitoring of building systems for buildings distributing over 250 kva Individual suite/tenant electrical monitoring required Watch out for: only prescriptive chapter without a trade-off path

28 Part 8: Energy Performance Compliance Points of note; MUST use ASHRAE 140 compliant software Proposed building must use the same or less energy than a building of the same shape, size, use, operation, and consumption profiles as a building built to prescriptive standard Watch out for: Can use trade-offs on reference building DO IT!!!

29 So what? an energy code; Is doing what we do more efficiently Requires design choices Needs an enforcement plan Has construction & inspection consequences Helps level the playing field

30 2011 National Energy Code Part 2 : Q&A time

31 Q: let s get to the point; how is this going to affect me?

32 PROCESS Q: what does this mean for approvals? A: our (Yours + City) processes should must reflect energy considerations early on

33 PROCESS Q: why might this matter to practice? A: Unlike the current life safety focus of the building code; building use, aesthetics, size and orientation will at least partially be influenced by NECB

34 PROCESS Q: what does this mean for approvals? A: implementing and enforcing energy codes demands more integration of Development Permit and Building Permit processes Note lack of goofy, distracting image here; please pay attention to the words

35 Q: where do we start?

36 PLANNING DEVELOPMENT PERMIT Q: what Development Permit items might be affected? Massing, Balconies/projections Use/marketing/cost Orientation/siting Glazing Quantity Distribution Appearance Transparency

37 PLANNING DEVELOPMENT PERMIT Q: what Development Permit items might be affected? Massing, Balconies/projections Use/marketing/cost Orientation/siting Glazing Quantity (FWDR for Calgary 33%) Distribution (S/E ; N/W ) Appearance (remember bronze glass?) Transparency (clarity is energy expensive) Pretty sure all this stuff matters to Planning

38 PLANNING DEVELOPMENT PERMIT Q: what does this mean for the built form?

39 PLANNING DEVELOPMENT PERMIT Q: what does this mean for the built form? =?

40 PLANNING DEVELOPMENT PERMIT Q: what does this mean for the built form? =?

41 Q: you need to see my what now?

42 SUBMITTALS BUILDING PERMIT Q: how will applications change? A: it starts with understanding compliance and the role of the design team

43 SUBMITTALS BUILDING PERMIT Q: and this looks like?

44 SUBMITTALS BUILDING PERMIT Q: and this looks like? Common submission document Required documents specific to the chosen compliance path Additional documentation that MAY be requested by the AHJ for verification

45 SUBMITTALS BUILDING PERMIT Q: what is this common submittal document? A: project compliance summary how why what who

46 SUBMITTALS BUILDING PERMIT Q: can we unpack this a bit? A: general conditions; answer why?

47 SUBMITTALS BUILDING PERMIT Q: can we unpack this a bit? A: basic building information; answer what?

48 SUBMITTALS BUILDING PERMIT Q: can we unpack this a bit? A: compliance summary: answer how?

49 SUBMITTALS BUILDING PERMIT Q: can we unpack this a bit? A: who is responsible for demonstrating compliance

50 SUBMITTALS BUILDING PERMIT Q: what will compliance look like? A: it depends on selected compliance path and how good your information is

51 SUBMITTALS BUILDING PERMIT Q: what will compliance look like? A: it depends on selected compliance path and how good your information is

52 SUBMITTALS BUILDING PERMIT Q: what is being done to coordinate submissions? A: the province (SCC) is developing training material to help AHJ s deal with NECB March??? We have pledged to share our submissions materials with other jurisdictions in the province Verification materials (templates, checklists, etc.) either use or are derived from NRCan materials this helps coordinate nationally as well as provincially

53 INSPECTIONS Q: what about inspections? A: inspections are also related to compliance path: Prescriptive This can be readily confirmed on site. This is the beauty of prescriptive

54 INSPECTIONS Q: what about inspections? A: inspections are also related to compliance path: Trade-Off Trade-off summaries are signed by professionals as required, or verified on site by inspectors or both

55 INSPECTIONS Q: what about inspections? A: inspections are also related to compliance path: Performance Compliance Professionals verify model comply with NECB, inspections verify compliance with models; design and as-built

56 Q: o.k. I m sold; what does the future really look like?

57 2011 National Energy Code Part 3 : soapbox

58 OPPORTUNITY Q: how does an AHJ show it cares? A: we will begin enforcing the energy code in the next couple months. We will try need to initiate; NECB compliance review of DP drawings to alert applicants of NECB compliance issues NECB as a basis for planning discussions, compromise, and exploration NECB submission forms and compliance review procedures

59 OPPORTUNITY Q: how do we move forward? A: We modernize and grow; Staff education Me. You. Us. Them. Approvals processes NECB + IDP + BIM = OMG! MITB Industry awareness Transparent. Intelligent. Informative. Policy adaptation Using regulation as a tool, not a barrier. More not fewer specialists Help Wanted! We keep on it
