Application Guide for Multi-Unit Residential

For New Construction & Major Retrofi ts LEED® Canada-NC Version 1.0

September 2005 Foreword The Canada Green 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 Guide This 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.

Acknowledgements The 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.

Disclosure The 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.

Application Guide for Multi-Unit Residential Buildings 3 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.

Development Density 1 Point

Intent Channel development to urban areas with existing infrastructure, protect greenfi elds and preserve habitat and natural resources.

Requirements Alternate Compliance Path for Multi-Unit Residential Buildings Only: Where a project meets the 13,800m2 per hectare Requirement (60,000 square feet per acre) but the surrounding site does not, then 6 of the 12 amenities listed below must be located either in the project or within 800 metres (1/2 mile) of the project: a. Community Centre and/or Youth Activity Centre b. General Offi ce c. Supermarket d. School e. Restaurant f. Post Offi ce g. Pharmacy h. Park/Recreational Facility i. Senior Care j. Medical/Dental k. Lawyer l. Café/Bakery

Submittals Provide the LEED Letter Template, signed by the civil engineer, architect or other responsible party, declaring that the project has the required number of amenities in or within 800 metres of the project; AND Provide an area plan with the project location highlighted, indicating the type and locations of all relevant amenities listed above. Include a scale bar for distance.

Summary of Referenced Standard There is no standard referenced for this Credit.

Interpretation With respect to amenities, they must already exist or be under construction to satisfy the above Requirements. Amenities planned in the area are not to be included.

Application Guide for Multi-Unit Residential Buildings 9 SS WE EA MR EQ ID Credit 4.2 1 Point Alternative Transportation: Bicycle Storage & Changing Rooms

Intent Reduce pollution and land development impacts from automobile use.

Requirements No change to Requirements.

Strategies There 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.

Canada Green Building Council 1100 SS WE EA MR EQ ID Credit 4.3 Alternative Transportation: 1 Point Hybrid and Alternative Fuel Vehicles

Intent Reduce pollution and land development impacts from automobile use.

Requirements Alternate 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.

Interpretation In 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

Application Guide for Multi-Unit Residential Buildings 1111 SS WE EA MR EQ ID Credit 4.3 Alternative Transportation: Hybrid and Alternative Fuel Vehicles (continued)

the procedures noted in the Reference Guide to estimate full-time equivalent (FTE) occupant load for non-residential areas.

Electrical refueling stations that service Neighbourhood Electric Vehicles (NEVs, also known as Low Speed Vehicles or LSVs) meet the Intent of this Credit.

NEVs are defi ned as follows: Any four wheeled electric vehicle with an attainable speed of more than 32 km/h (20 mph) and not more than 40 km/h (25 mph). NEVs/LSVs should not be confused with golf carts, which commonly have a lower maximum speed, or all terrain vehicles that are primarily intended for off-road use. Highly fuel-effi cient vehicles are defi ned as: Any fossil fuel powered four wheeled vehicle that meets or exceeds 25 km/liter (60 mpg).

Canada Green Building Council 1122 SS WE EA MR EQ ID Credit 4.4 Alternative Transportation: Parking Capacity 1 Point

Intent Reduce pollution and land development impacts from single occupancy vehicle use.

Requirements Alternate Compliance Path for Multi-Unit Residential Buildings Only: For residential projects, size parking capacity to meet, but not exceed, minimum local zoning requirements; AND EITHER Participate in an existing car sharing or car co-op program that can accommodate at least 5% of the building occupants, with parking for these vehicles located within 800 metres (1/2 mile) of the project (can be either on- or off-site) OR provide vehicles with dedicated parking on-site for car co-operatives or car sharing programs that can accommodate at least 5% of the building occupants; OR For residential projects, provide 20% less parking than required by the standard local zoning by-law requirements for residential projects in the general area of the development.

Submittals For residential projects provide: - The LEED Letter Template, signed by the civil engineer or other responsible party, stating any relevant minimum zoning requirements and declaring that parking capacity is designed to meet, but not exceed them. In the event of an audit of this Credit, provide a description of the car co-op or car sharing strategy, a copy of a car share or co-op contract, AND provide a highlighted area plan that shows the project at the centre of a circle of 800 metres (1/2 mile) radius, and car sharing or car co-op parking sites within this radius that can accommodate at least 5% of the building occupants OR provide vehicles with preferred parking on-site for car co-ops or car sharing that service at least 5% of the total building occupants. Show calculations indicating target percentages have been met. OR For residential projects provide: - The LEED Letter Template, signed by the civil engineer or other responsible party, stating any relevant minimum zoning requirements in

Application Guide for Multi-Unit Residential Buildings 1133 SS WE EA MR EQ ID Credit 4.4 Alternative Transportation: Parking Capacity (continued)

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

Calculation The 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.

Interpretation In 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.

Canada Green Building Council 1144 Water Effi ciency SS WE EA MR EQ ID Credit 2 Innovative Wastewater Technologies 1 Point

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

Requirements For 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 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.

Calculation In 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.

Application Guide for Multi-Unit Residential Buildings 1155 SS WE EA MR EQ ID Energy & Atmosphere Prerequisite 2 Required Minimum Energy Performance

Intent Establish the minimum level of energy effi ciency for the base building and systems.

Requirements Option 3 - Low- and High-rise Multi-unit Residential Buildings: EFFECTIVE UNTIL DECEMBER 31, 2006: The project must be registered under LEED Canada on or before December 31st, 2006, AND a building permit must be issued within 12 months of December 31st, 2006 in order to be eligible for this option; EFFECTIVE JANUARY 1, 2007: Starting January 1st, 2007, the existing LEED Canada-NC 1.0 Requirements for new and existing buildings as described in Options 1 and 2 will come into effect for low- and high-rise residential buildings. Option 3 for low- and high-rise multi- unit residential projects will no longer be available.

Design the building to comply with ASHRAE/IESNA Standard 90.1-1999 (without amendments) or 10% better than the Model National Energy Code for Buildings - 1997 (MNECB), based on energy consumption or the local energy code, whichever is more stringent. A modeling path (not the prescriptive path) must be used to demonstrate compliance. To establish savings relative to the MNECB, the calculation of percentage energy reduction shall be in accordance with the procedures used in CBIP (i.e. includes “non-regulated” plug loads but excludes process equipment); AND Computer modeling should follow the procedures in Part 8 of the MNECB 1997 for projects using MNECB compliance, and the procedures described in ASHRAE/IESNA 90.1-1999 for projects using ASHRAE compliance. All projects shall follow the modeling guidelines in the most recent version of Natural Resources Canada “Procedures for Modeling Buildings to CBIP and MNECB”.

Submittals Provide a LEED Letter Template, signed by a licensed professional engineer or architect, stating that the building complies with the appropriate energy performance level (defi ned above);. AND

Canada Green Building Council 1166 SS WE EA MR EQ ID Prerequisite 2 Minimum Energy Performance Required (continued)

For CBIP Projects reviewed and approved by Natural Resources Canada: Provide a copy of the letter from Natural Resources Canada indicating that the building qualifi es for the CBIP program and passes LEED EAp2 requirements. For CBIP Projects not reviewed by NRCan or ineligible CBIP Projects: Provide a review report by an independent CBIP Design Assessor indicating that the design meets the Requirements of this Prerequisite; OR Provide an electronic copy of the computer simulation fi les, checklist of mandatory items met and documentation supporting the claimed energy savings, including architectural, mechanical and electrical drawings and specifi cations in electronic form. For ASHRAE 90.1 Projects: Provide an electronic copy of the Energy Cost Budget and fi nal Proposed Design computer simulation fi les, checklist of mandatory items met and documentation supporting the claimed energy savings, including architectural, mechanical and electrical drawings and specifi cations in electronic form.

Application Guide for Multi-Unit Residential Buildings 1177 SS WE EA MR EQ ID Credit 5 1 Point Measurement and Verifi cation

Intent Provide for the ongoing accountability and optimization of building energy and water consumption performance over time.

Requirements For Multi-Unit Residential Buildings only: Measurement and verifi cation will rely on building level information. Continuous metering equipment should be installed to measure and verify the following: Total annual building energy consumption (including all energy sources for both common and private/suite spaces) Annual energy consumed (by source) including: - Natural Gas - Fuel Oil - Electricity Common energy consuming equipment including: - Central boiler - Chiller/air conditioning - Make-up air unit - Total common area electricity including , , etc. - Signifi cant base-building process loads such as indoor and hot tubs (if included) Annual whole building water consumption.

Submittals Provide the LEED Letter Template, signed by the licensed engineer or other responsible party, indicating that metering equipment has been installed and the measurement and verifi cation option to be followed under IPMVP version 2001. In the event of an audit of this Credit, provide a copy of the M&V plan following IPMVP, version 2001, including an executive summary.

Interpretations The sources of this information should be on-site meters and utility data, recogniz- ing that suite level information will not be available for privately owned or rental dwelling units with separate utility billing. As such, M&V information on common areas is suffi cient. The analysis of this information should be done annually and include energy con- sumption, normalized energy consumption by square metres of conditioned fl oor area and degree-days, water consumption and normalized water consumption by square metres of conditioned fl oor area.

Canada Green Building Council 1188 Indoor Environmental Quality SS WE EA MR EQ ID Prerequisite 2 Environmental Tobacco Smoke (ETS) Control Required

Intent Prevent or minimize exposure of building occupants, indoor surfaces and systems to Environmental Tobacco Smoke (ETS).

Requirements Choose one of the following compliance options for residential buildings: Option 2 - Establish negative pressure in the rooms with smoking. • Prohibit smoking in the building except in designated smoking areas. • Locate any exterior designated smoking areas at least 7.5 metres (25 feet) away from entries, outdoor air intakes and operable . • Provide one or more designated smoking rooms (including individual residential suites) designed to effectively contain, capture and remove ETS from the building. At a minimum, the smoking /suite must be directly exhausted to the outdoors with no re-circulation of ETS-containing air to the non-smoking area of the building, enclosed with impermeable -to-deck partitions; and operated at a negative pressure compared with the surrounding spaces of at least 5 Pa (0.02 inches of water gauge) with a minimum of 1Pa (0.004 inches of water) when the (s) to the smoking room/suite are closed. • Performance of the smoking room/suite differential air pressures shall be verifi ed by conducting 15 minutes of measurement, with a minimum of one measurement every 10 seconds, of the differential pressure in the smoking room/suite with respect to each adjacent area and in each adjacent vertical chase with the to the smoking room/suite closed. The testing will be conducted with each space confi gured for worst case conditions of transport of air from the smoking rooms/suites to adjacent spaces.

Option 3 - Reduce air leakage between rooms with smoking and non-smoking areas in residential buildings. • Prohibit smoking in all common areas of the building. • Locate any exterior designated smoking areas at least 7.5 metres (25 feet) away from entries, outdoor air intakes and operable windows opening to common areas. • Minimize uncontrolled pathways for ETS transfer between individual residential units by sealing penetrations in , and fl oors in the residential units, and by sealing vertical chases adjacent to the units.

Carbon Dioxide (CO2) Monitoring 1 Point

Intent Provide capacity for indoor air quality (IAQ) monitoring to help sustain long-term occupant comfort and well-being.

Requirements For Multi-Unit Residential Buildings only: Carbon monoxide (CO) alarms installed in suite and common spaces near combustion equipment; AND IAQ testing of all suites at the end of construction and immediately prior to occupancy to develop a baseline indoor air quality profi le. 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.

Application Guide for Multi-Unit Residential Buildings 2211 SS WE EA MREQ ID Credit 2 1 Point Ventilation Effectiveness

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

Requirements Alternate 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 Strategies This 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.

Canada Green Building Council 2222 SS WE EA MREQ ID Credit 3.2 Contruction IAQ Management Plan: 1 Point Testing Before Occupancy

Intent Minimize 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.

Requirements Alternate 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 Concentration Particulate Matter (PM10) 50 ug/m3 Formaldehyde 50 parts per billion Total Volatile Organic Compounds 500 ug/m3 Carbon Monoxide 9 PPM and no greater than 2 PPM above outdoors 4-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.

Application Guide for Multi-Unit Residential Buildings 2233 SS WE EA MREQ ID Credit 3.2 1 Point Contruction IAQ Management Plan: Testing Before Occupancy (continued)

Interpretations The Option 1 and Option 2 compliance paths for building fl ush procedures of LEED Canada-NC 1.0 are also acceptable compliance paths.

Canada Green Building Council 2244 SS WE EA MREQ ID Credit 5 Indoor Chemical & Pollutant Source Control 1 Point

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

Requirements Alternate Compliance Path for Multi-Unit Residential Buildings Only: Design to minimize pollutant cross-contamination of regularly occupied areas: • Employ permanent 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.

Application Guide for Multi-Unit Residential Buildings 2255 SS WE EA MREQ ID Credit 5 1 Point 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.

Strategies The 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.

Canada Green Building Council 2266 SS WE EA MREQ ID Credit 6.1 Controllability of Systems: Perimeter Spaces 1 Point

Intent Provide 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.

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

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.

Interpretations For low- and high-rise residential projects, sliding glass and other doors leading to exterior 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.

Application Guide for Multi-Unit Residential Buildings 2277 SS WE EA MREQ ID Credit 6.2 1 Point Controllability of Systems: Non-Perimeter Spaces

Intent Provide 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.

Requirements Alternate 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.

Submittals For 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.

Canada Green Building Council 2288 SS WE EA MREQ ID Credit 7.2 Thermal Comfort: Monitoring 1 Point in addition to Intent EQ 7.1 Provide a thermally comfortable environment that supports the productivity and well-being of building occupants.

Requirements Alternate 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.

Interpretation Where Humidity “control” is required, it can be addressed by providing humidistats in and 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.
