CITY OF CALGARY

LEED V4

• Currently all projects are designed to LEED 2009 under CaGBC

• LEED V4 is a major change and will take effect in Q4 of 2016

• “LEED v4 is the newest update to the LEED rating systems.Changes from LEED 2009 are seen in three main categories:new market sectors, increased technical rigor and streamlinedservices. LEED v4 raises the bar on leadership.”

23

LEED V4

• Major changes include

• New category, Location & Transportation (LT)

• New Site Assessment credit within SS category

• Shift from Stormwater Design to Rainwater Management

• Light Pollution credit calculation

– Backlight-Uplight-Glare (BUG) method, or,

– Calculation Rating method

• Major goal is Carbon Reduction

• Metering credit is pre-requisite for energy and water andincludes annual reporting

WHAT’S NEW IN NECB 2011?

• Part 8 – Power

o New minimum efficiencies fortransformers (eg: 600V – 208V)

o Services of 250kVA and larger requireinfrastructure to accommodate meteringof energy consumption of:

o HVAC,

o Interior lighting, &,

o Exterior lighting.

24

• Div A, Part 1.4.1.2 – Defined Terms

– Any space within a building envelope, conditioned or unconditioned

– Sheltered space

• Storage garage, parking garage, bus shelter, retail outlet

• Covered walkway, when the walkway itself is illuminated

INTERIOR LIGHTING APPLICATION


• Part 4.2.1 – Lighting

o Reduced LPD for some spaces (W/m2) with respectto 1997 standard

– Office is 9.7 compared to 17

– University is 10.7 compared to 12

o Increased LPD for others

– Hospital Treatment room is 18 compared to 15

– Hospital Radiology room is 14 compared to 4

o Watt Allowance

25


• Part 4.2.1.4 – Lighting exceptions

• There are exceptions to interior lightingprovided the exceptions are in addition togeneral lighting

• Example, retail display window lighting provided the area is fully enclosed

• Example, lighting integral to equipment installed by manufacturer

• Example, lighting for plant growth


• Part 4.2.2 – Lighting and Controls

o Automatic shut-off required in all spaces

– Control via time of day, such as officehours

– Control via occupancy sensor for 30minutes of inactivity

o Automatic control: manual on orautomatic on

– Exceptions include public areas likecorridors, restrooms, patient care, etc.

o Circuit Breaker control not allowed

26


• Part 4.2.2.2 – Lighting Controls

o Enclosed spaces must have atleast one control device

o Activation can be manual orautomatic but automatic shutoff isrequired

o Hotel/motel/temporaryaccommodation must have auto-off for bathroom lighting within 60minutes


• Part 4.2.2.3 – Additional LightingControl required for:

• Furniture mounted task lightingcontrolled by automatic shutoff andhas integral or wall mounted controldevice

• Guest/rental room or suite lighting

27


• Part 4.2.2.3 – Additional LightingControl required for:

• Separate control device for:

– Display or accent lighting

– Display case lighting

– Plant growth

– Food warming

– For sale or education


• Part 4.2.2.4 – Daylight controls forToplighting

o Daylight controls are required fordaylight zones larger than 400m2

28


• Part 4.2.2.8 – Daylight controls forSidelighting

o Daylight controls are required fordaylight zones larger than 100m2


• Part 4.2.2 – Lighting Controls

o Automatic shut-off required in sheltered spaces such as parkinggarage, bus shelters and retail outlets

– Control via time of day, such as operation hours

– Control via occupancy sensor for 30 minutes of inactivity

29


• Part 4.2.4 – Exterior Lighting Control

o Must be controlled via time control andphotosensors

o Dusk-to-dawn can have either-or

o Exception are safety, security or eyeadaption

HOW TO ENSURE COMPLIANCE

o Mandatory commissioning forall controls including functionaltesting.

30

WHY DOES IT MATTER

• Approach to design must change

o Consider lighter finishes

o Prewire furniture wiring details willchange as automatic control, perfurniture integrated luminaire, isrequired

o Parking structures must havepainted walls and ceilings

o Cannot use slim profile luminaireseverywhere

WHY DOES IT MATTER

• Electrical budgets cannot be “valueengineered”

o Money required for controls ingeneral

o Everything to be accounted for,decorative and functional

31

WHY DOES IT MATTER

• Lighting concept must be establishedearly to identify general versus accentlighting including ceiling types andfinishes

• Retail chains may not be able to use thesame design; new lighting concept maybe required to meet lower LPD’s

ALTERNATE COMPLIANCE

Currently there is NONE in Alberta

• May have to run parallel exercises if using ASHRAE & NECB (LEED projectfor example) but it results in increased soft cost

• Generally, NECB can result in 10% - 18% savings beyond ASHRAE

32

COMPARISON TO PROPOSED ALTERNATE

ASHRAE

• Energy cost based

• Trade-off paths in envelope only

• Can exclude task lighting

• Lighting alterations in scope

• Parking lot lighting controls inscope

• Receptacle control in scope

• Elevator restrictions in scope

NECB

• Energy based

• Trade-off paths within envelope,HVAC and lighting

• Cannot exclude task lighting

• Lighting alterations not in scope

• Parking lot lighting controls not inscope

• Receptacle control not in scope

• Elevator restrictions not in scope

NEXT STEPS…

Project start-up meeting steps:

1. Define the project and project goals,

2. Verify which codes are applicable,

3. Is LEED certification required,

4. Decide as a team how to pursuecompliance with NECB,

5. Calculate Watt allowance,

6. Have fun…
