ForewordThe Canada Green Building Council established a special Task Force to address important issues arising from the market uptake of the LEED® Canada-NC Green Building Rating System. The CaGBC instructed the Multi-unit Residential Building (MURB) Task Force to develop a discussion paper outlining key issues for MURBs, to assist users with the special challenges and non-technical questions of this building type with LEED Canada Prerequisites and Credits.The MURB Task Force prepared an Actions and Recommendations paper for the CaGBC that set out additional strategies for LEED Credits as they relate to LEED Canada-NC 1.0. The Task Force recommended the creation of a Low- and High-rise Residential Application Guide to supplement LEED Canada-NC.

The Low- and High-rise Residential Application GuideThis LEED Canada-NC 1.0 Application Guide was prepared to provide additional clarifi cation on Requirements and Submittals for low- and high-rise multi-unit residential buildings as they relate to particular LEED Credits. This guide highlights only those alternate compliance Requirements and Submittals for specifi c Prerequisites and Credits that required clarifi cation for these building types, and for mixed-use buildings that include residential occupancies. Any Requirements outlined in this document are in addition to those already documented in LEED Canada-NC 1.0 for specifi c Credits; and should not be used for other occupancies, except as noted for mixed-use buildings with a residential component. The existing compliance paths described in the LEED Canada-NC 1.0 rating system are still available to MURB projects; the alternative compliance paths described herein are in addition to those compliance paths.As well, this Application Guide provides some common defi nitions and terms, and refi nes others for the low- and high-rise multi-unit residential context.

AcknowledgementsThe MURB Task Force and the preparation of the Application Guide could not have been undertaken without the fi nancial support of the Greater Vancouver Regional District and the Canada Mortgage and Housing Corporation. The CaGBC is greatly indebted for the unfl agging support of these organizations.The CaGBC would also like to acknowledge the efforts of the CaGBC’s Product Steering Committee and the LEED Technical Advisory Group for their input into the preparation of this Application Guide. The Application Guide process was managed by BuildGreen Developments Inc. with assistance from CaGBC staff, and included the review and suggestions of many TAG members. We extend our deepest gratitude to all these individuals and the MURB Task Force for their volunteer efforts and constant support of CaGBC’s mission.

DisclosureThe Canada Green Building Council (CaGBC) has been offi cially established as a national not-for-profi t corporation and it has signed a Licensing Agreement with the US Green Building Council (USGBC) for the exclusive implementation of the LEED Green Building Rating System in Canada.LEED Canada is a derivative work of the USGBC’s LEED® Green Building Rating System. LEED Canada and its companion LEED Canada Reference Guide are intended to facilitate the use of the LEED Green Building Rating System in Canada. The LEED Canada-NC Rating System and its companion LEED Canada-NC Reference Guide serve two distinct roles:1. Where appropriate, they provide a set of equivalent Canadian LEED Prerequisite and Credit Requirements, including references to relevant Canadian standards and resource material.


2. They provide guidelines to assist Canadian organizations and jurisdictions in the creation of Supplements that provide a further level of refi nement specifi c to their specialized needs.LEED Canada-NC version 1.0 is modeled on the USGBC’s LEED NC-2.1, and is applicable to new designs and major renovations of new commercial buildings, institutional buildings and low- and high-rise multi-unit residential buildings. Through its use as a design guideline and third-party certifi cation tool, LEED aims to improve the occupant well-being, environmental performance and economic return of buildings using established and innovative practices, standards and technologies. It provides a defi nition, widely accepted by industry, for what currently constitutes a “green building.” LEED Canada consists of an explicit set of environmental performance criteria, organized within fi ve (5) key performance categories: Sustainable Sites; Water Effi ciency; Energy and Atmosphere; Materials and Resources; and Indoor Environmental Quality. A sixth category, Innovation & Design Process, rewards exceptional environmental performance or innovation over and above that explicitly covered in the basic LEED Credits.LEED Canada lays out the basic Intent, Requirements and Submittals that are necessary to achieve each Prerequisite and voluntary Credit. Projects earn one or more points toward certifi cation by meeting or exceeding each Credit’s technical Requirements. All Prerequisites must be achieved in order to qualify for certifi cation. Points for each Credit contribute to a fi nal score that relates to one of four possible levels of certifi cation: LEED CERTIFIED, SILVER, GOLD or PLATINUM. The LEED Canada Checklist is a summary of Credit topics and point values crafted to assist users to track progress in greening their projects. A short description of technologies and strategies is included for each Credit to briefl y inform those who are unfamiliar with the particular topic. The LEED Canada-NC 1.0 Reference Guide—the technical companion to the Rating System and Letter Template—provides further background, explanation and instruction.

1 Point Alternative Transportation: Bicycle Storage & Changing Rooms

IntentReduce pollution and land development impacts from automobile use.

RequirementsNo change to Requirements.

StrategiesThere is no Requirement for where bicycle storage may be located in a residential or mixed-use building. Unfortunately, many buildings locate bike storage facilities in the underground parking, making getting bikes to the surface a challenge. This Application Guide encourages MURB projects to locate bike storage facilities at or close to grade and near entrances/exits to the building, with easy passage be-tween the storage and entry/exit, so as to easily accommodate bike movement and encourage bike use.

Alternative Transportation: Hybrid and Alternative Fuel Vehicles

IntentReduce pollution and land development impacts from automobile use.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Hybrid, alternative fuel and/or highly fuel-effi cient vehicles will be accessible to at least 3% of building occupants through a car share or car co-op facility. The facility must be located within 800m of the project site (either on- or off-site).

Submittals� Provide the LEED Letter Template with a drawing indicating the project

site, the car share/car co-op parking location and a scale bar for distance. Provide a copy of the contract with the car share/car co-op indicating that their infrastructure will be actively marketed to project residents for at least two years after occupancy and that they have acquired the required number of hybrid, alternative fuel and/or highly fuel-effi cient vehicles to service the project;

OR,� Provide a copy of the building’s car share/car co-op management program

and proof of vehicle ownership of, or minimum 2 year lease agreement(s) for the hybrid, alternative fuel and/or highly fuel-effi cient vehicle(s). Provide calculations indicating that at least 3% of building occupants will be serviced by the car share/car co-op facility.

Calculation 1. Identify the number of occupants in the building. Multiply the number of occupants by 3% to obtain the number of people to be served by the car sharing program (‘PPCSP’). 2. Divide PPCSP by 20 (the number of estimated shared cars required to meet the demand) to obtain the number of shared vehicles required to service 3% of the building’s occupants. 3. Round decimal amounts up to the nearest whole number.

InterpretationIn mixed-use projects the commercial component can also use the above Requirements and Submittals to demonstrate compliance for residential portions of the project. Non-residential portions of mixed-use developments should follow

the general surrounding area and declaring that parking capacity is designedto be at least 20% less than this requirement.

CalculationThe following is the calculation methodology to be used in determining the amount of vehicles required for a car share program whether provided on-site or through participation in a car share program. 1. Identify the number of occupants in the building. Multiply the number of occupants by 5% and divide by two to obtain the number of people to be served by the car sharing program (‘CSP’). 2. Divide CSP by 20 (the number of estimated car share cars required to meet the demand) to obtain the number of car share vehicles required to service 3% of the building’s occupants. 3. Round decimal amounts up to the nearest whole number to obtain the number of vehicles and parking required.

InterpretationIn mixed-use projects the commercial component can also use the above Require-ments and Submittals to demonstrate compliance for residential portions of the project. Non-residential portions of mixed-use developments should follow the procedure noted in the Reference Guide to estimate full-time equivalent (FTE) oc-cupant load for non-residential areas.In achieving the 20% less requirement it is understood that some projects may be able to convince local zoning authorities to reduce the parking zoning bylaw re-quirements for a particular site as compared to nearby surrounding sites. As such, those projects that can demonstrate a 20% reduction to statutory parking require-ments as compared to these surrounding areas can earn this Credit.


1 PointInnovative Wastewater Technologies

IntentReduce generation of wastewater and potable water demand while increasing the local aquifer recharge.

RequirementsFor Multi-Unit Residential Buildings only:Reduce the use of municipally provided potable water for building sewage conveyance by a minimum of 40%.

Submittals� Provide the LEED Letter Template, signed by the architect, mechanical

or plumbing engineer or other responsible party, declaring that water for building sewage conveyance will be reduced by at least 40% for residential projects. Include the spreadsheet calculation and a narrative demonstrating the measures used to reduce wastewater by at least 40% for residential projects from baseline conditions.

CalculationIn calculating residential wastewater reductions there will likely be no urinals in the baseline or design case as these fi xtures are typically not provided in residential building design. Therefore, assume building occupants are 50% male and 50% female with usage of toilets once a day for solids and twice a day for urine for both male and female. The calculations should be based on a 365 day period for both the design and baseline case.

The indoor air quality profi le will be conducted for a representative sample of suites using the progressive sampling methodology defi ned below. Sampling will be performed by either a certifi ed industrial hygienist or a licensed engineer and meet the following criteria: • < 5 mg/m3 of formaldehyde (State of Washington Program and IAQ Standards) • < 5 mg/m3 of total volatile organics (State of Washington Program and IAQ Standards) • < outside air level + 700 ppm of carbon dioxide (ASHRAE 62-2001) • < 9 ppm of carbon monoxide (NAAQS 8hr) • < 5 mg/m3 of airborne particulates (OSHA PEL)

Submittals� For low- and high-rise residential projects, provide the LEED Letter Template,

signed by the mechanical engineer, certifi ed industrial hygienist or other responsible party, declaring and summarizing the installation, and the CO alarm system in appropriate areas. Provide baseline testing results indicating pollutant limits were met.

In the event of an audit of this Credit, Submittals should include:� Tests conducted in accordance with the referenced standards for at least

10% of the fi rst 100 dwelling units in the building and 5% of any additional units. (For example, a 150 unit building would be required to test a total of 10+2.5=13 dwelling units.) Distribution of the tested units should refl ect wind and buoyancy conditions experienced by the building, i.e. on different faces and elevations in the building and fl oors.

1 Point Ventilation Effectiveness

IntentProvide for the effective delivery and mixing of supply air to support the safety, comfort and well-being of building occupants.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:For mechanically ventilated low- and high-rise residential buildings, design ventilation systems to provide outside air through a central or individual system, ducted directly to the suite with air distributed to all regularly occupied areas in the suite.

Submittals

� For mechanically ventilated low- and high-rise residential projects, provide the LEED Letter Template, signed by the mechanical engineer or other responsible party, declaring that outside air provided is ducted directly to the suite, with air distributed to all regularly occupied areas in each suite. Include a narrative describing the ventilation system(s) and air delivery within the suites.

� Provide a report summarizing airfl ow (CFD or nodal airfl ow) simulation results for each regularly-occupied zone type in both heating and cooling modes. The report should include a brief narrative describing system operational modes, graphics showing zone and building airfl ow patterns with local winds in each cardinal and prevailing direction, and identify the computational fl uid dynamics or network airfl ow modeling program used.

Potential StrategiesThis proposed alternate compliance path for MURBs encourages the direct ducting of outside air into each suite through a central or individual system. This Credit further requires the movement of this outside air through to all regularly occupied areas of the suite. Central and individual HRVs are a technology that can jointly meet this Credit as well as earn energy effi ciency points under EAc1. Many low- and high-rise residential projects do not give due attention to ventilation issues and this Credit will encourage more developers to improve ventilation performance.

Contruction IAQ Management Plan: Testing Before Occupancy

IntentMinimize indoor air quality problems resulting from the construction/renovation process in order to help sustain the comfort and well-being of construction workers and building occupants.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Develop and implement an Indoor Air Quality (IAQ) Management Plan for the pre-occupancy phase that follows one of the two options below:� Conduct baseline IAQ testing, after construction ends and prior to occupancy,

using testing protocols consistent with the United States Environmental Protection Agency “Compendium of Methods for the Determination of Air Pollutants in Indoor Air”, and as additionally detailed in the LEED Canada- NC Reference Guide;

OR,� Demonstrate that the contaminants listed below are not exceeded; remediate

causes and repeat procedure until all requirements have been met.

Contaminant Maximum ConcentrationParticulate Matter (PM10) 50 ug/m3

Formaldehyde 50 parts per billionTotal Volatile Organic Compounds 500 ug/m3

Carbon Monoxide 9 PPM and no greater than 2 PPM above outdoors4-Phenycyclohexene (4-PC) * 6.5 ug/m3

* Required only if carpets with Styrene Butadiene (SB) latex backing material are installed.

Submittals� Provide a copy of the IAQ testing results indicating that the air quality testing

has been completed and maximum chemical contaminant concentration requirements are not exceeded in the areas tested.

Calculations� The tests should be done for at least 10% of the fi rst 100 dwelling units in the

building and 5% of any additional units. (For example, a 150 unit building would be required to test a total of 10+2.5=13 dwelling units.) Distribution of the tested units should attempt to be a relative selection of different units with different elevations in the building and on different fl oors.

Indoor Chemical & Pollutant Source Control

IntentMinimize exposure of building occupants to potentially hazardous particulates, biological contaminants and chemical pollutants that adversely impact air and water quality.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Design to minimize pollutant cross-contamination of regularly occupied areas:

• Employ permanent entryway systems (grilles, grates, etc.) to capture dirt, particulates, etc. from entering the building at all high volume entryways.

• Where hazardous gases or chemicals may be present or used (including garages, high-volume housekeeping/laundry areas and copying/printing rooms), provide segregated areas with deck-to-deck partitions with separate outside exhaust at a rate of at least 9.2 cubic metres per hour per square metre (0.50 cubic feet per minute per square foot), no air re-circulation, and operated at a negative pressure compared with the surrounding spaces of at least an average of 5 Pa (0.02 inches of water gauge) and with a minimum of 1 Pa (0.004 inches of water) when the door(s) to the room(s) are closed.

• Provide containment drains plumbed for appropriate disposal of hazardous liquid wastes in places where water and chemical concentrate mixing occurs for maintenance or laboratory purposes.

• Replace all fi ltration media immediately prior to occupancy. Filtration media shall have a Minimum Effi ciency Reporting Value (MERV) of 13, as determined by ASHRAE 52.2-1999 for media installed at the end of construction.

Submittals� Provide the LEED Letter Template, signed by the architect or other responsible

party, declaring that: • Permanent entryway systems (grilles, grates, etc.) to capture dirt,

particulates, etc. are provided at all high volume entryways. • Chemical-use areas and copy rooms have been physically separated with

deck-to-deck partitions and self-closing doors, and independent exhaust ventilation has been installed that meets Credit Requirements.

• In spaces where water and chemical concentrate mixing occurs, drains are plumbed for environmentally appropriate disposal of liquid waste as determined by applicable regulations and standards.

Indoor Chemical & Pollutant Source Control(continued)

Interpretations• For low- and high-rise residential projects using 100% fresh air systems with

no re-circulated air, the MERV 13 fi ltration requirement is not required for systems serving dwelling units only.

• Selection of HVAC equipment serving a single dwelling unit, including heat recovery ventilators, should specify that the best available fi ltration media shall be provided for the initial installation.

• For mixed-use buildings, where the residential component is the primary use in the building, and mechanical equipment in commercial building spaces each supply less than 283L/s (600 CFM) of recirculated air, HVAC equipment serving such commercial spaces do not need to meet the MERV 13 requirement .However, the best available fi ltration media shall be provided with the initial installation of HVAC equipment.

StrategiesThe practice of ducting air directly to suites, using central or individual ventilation systems that encourage heat recovery, is encouraged in residential design rather than corridor pressurization. Individual heat recovery systems to residential units brings fresh air directly to suites, exhausts that air and recovers heat as it leaves the building. Utilizing these strategies, outdoor air is not recirculated within the building and the MERV 13 is not required.

Controllability of Systems: Perimeter Spaces

IntentProvide a high level of thermal, ventilation and lighting system control by individual occupants or specifi c groups in multi-occupant spaces (i.e. classrooms or conference areas) to promote the productivity, comfort and well-being of building occupants.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Provide at least an average of one operable window and one lighting control zone per 18.5m2 (200 ft2) for all regularly occupied areas within 5 metres (15 feet) of the perimeter wall.

Submittals� Provide the LEED Letter Template, signed by the architect or other responsible

party, demonstrating and declaring that for regularly occupied perimeter areas of the building, a minimum of one operable window and one lighting control zone are provided per 18.5m2 (200 ft2) on average.

InterpretationsFor low- and high-rise residential projects, sliding glass and other doors leading to exterior balconies should also be included as an “operable window” for this Credit as they serve the same function as a window in terms of ventilation control.

Controllability of Systems: Non-Perimeter Spaces

IntentProvide a high level of thermal, ventilation and lighting system control by individual occupants or specifi c groups in multi-occupant spaces (i.e. classrooms or conference areas) to promote the productivity, comfort and well-being of building occupants.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Provide at least one control for airfl ow and lighting for each regularly occupied non-perimeter area. If there are no regularly occupied non-perimeter spaces, the project meets the Intent of this Credit and earns this point, providing that EQc6.1 is met.

SubmittalsFor low- and high-rise residential projects, provide the LEED Letter Template, signed by the architect or other responsible party, demonstrating and declaring that at least one control for individual airfl ow and lighting are provided for each regularly occupied non-perimeter area.


Thermal Comfort: Monitoring

IntentProvide a thermally comfortable environment that supports the productivity and well-being of building occupants.

RequirementsAlternate Compliance Path for Multi-Unit Residential Buildings Only:Provide a permanent monitoring system to ensure building performance to the desired comfort criteria as determined by EQ Credit 7.1, Thermal Comfort - Compliance.

Submittals� Provide the LEED Letter Template, signed by the engineer or other responsible

party, identifying the comfort criteria, strategy for ensuring performance to the comfort criteria, description of the permanent monitoring system implemented and process for corrective action as may be appropriate;

AND EITHER � Confi rm that the temperature, airfl ow and humidity controls (if applicable)

were (or will be) tested as part of the scope of work for Energy and Atmosphere Prerequisite 1, Fundamental Building Systems Commissioning. Include the document name and section number where the commissioning work is listed;

OR� Where humidity control is not provided, provide the LEED Letter Template,

signed by the engineer or responsible party, declaring that humidifi cation/dehumidifi cation equipment is neither required nor installed.

InterpretationWhere Humidity “control” is required, it can be addressed by providing humidistats in bathroom and kitchen spaces to remove excess humidity. Each residential unit will then be able to control their comfort through removing excess humidity with the humidistat, with temperature controlled as per Credit Requirements. With increasingly tight residential building envelopes, and with residential uses, adding humidity is not recommended as an appropriate strategy. Excess humidity exhausting strategies are the norm and are encouraged to improve thermal comfort.
