    "Care Occupancy. Support services rendered by or through care facility management refer to services provided by the organization that is responsible for the care for a period exceeding 24 consecutive hours. They do not refer to services arranged directly by residents with outside agencies. They do not include services provided to a family member.

    In the context of care occupancies, these services may include a daily assessment of residents’ functioning, awareness of their whereabouts, the making of appointments for residents and reminding them of those appointments, the ability and readiness to intervene if a crisis or emergency arises for a resident, supervision in areas of nutrition or medication, provision of transient medical services, and assistance in case of emergency or building evacuation. Services may also include activities of daily living such as bathing, dressing, feeding, and assistance in the use of washroom facilities, etc. No actual treatment is provided by or through care facility management.

    Care occupancies offering lodging in rooms include nursing homes, rehabilitation centres, palliative care facilities, convalescent homes, birthing centres and private seniors’ residences.

    Care occupancies offering lodging in dwellings include private seniors’ residences where services or care may be provided.

    Care occupancies do not include residential and long-term care centres (CHSLDs) within the meaning of the Act respecting health services and social services or any other occupancy with a similar use.";

    "Treatment Occupancy. "Treatments" may include such things as surgery, intensive care and emergency medical intervention. Treatment services differ from the services provided by care occupancies, like personal care assistance or the administration of medication, and from those provided by business and personal services occupancies, like dentistry.

    Treatment occupancies include residential and long-term care centres (CHSLDs) within the meaning of the Act respecting health services and social services and any other occupancy with a similar use.";

    "Suite. The term "suite" applies to both rental and ownership tenurBe.-1I.n1, a condominium arrangement, for example, dwelling units are considered

    separate suites. In order to be of complementary use, a series of rooms that constitute a suite must be in reasonably close proximity to each other and have access to each other either directly by means of a

    arrangement.

    The term "suite" does not apply to rooms such as service rooms, common laundry rooms and common recreational rooms that are not leased or under a separate tenure in the context of the NBC. Similarly, the term "suite" is not normally applied in the context of buildings such as schools and hospitals, since the entire building is under a single tenure. However, a room that is individually rented is considered a suite. A compartment or warehousing unit in a mini-warehouse is a suite.

    For certain requirements in the NBC, the expression "room or suite" is used (e.g., travel distance). This means that the requirement applies within the rooms of suites as well as to the suite itself and to rooms that may be located outside the suite. In other places the expression "suite, and rooms not located within a suite" is used (e.g., for the installation of smoke and heat detectors). This means that the requirement applies to individual suites as defined, but not to each room within the suite. The rooms "not within a suite" would include common laundry rooms, common recreational rooms and service rooms, which are not considered as tenant-occupied space.

    A room occupied by a patient or resident in a care or treatment occupancy is not a suite within the meaning of the NBC. A room is a single sleeping room that may include sanitary facilities.";

    Insert the following Notes, respecting the alphabetical order:

    "Alteration. An alteration does not include the types of work such as work required to bring the building into conformance with the regulations in force and the maintenance and repairs that do not affect the characteristics and functions of the elements involved. It does, however, include the following types of intervention:

    1. a change of occupancy without modification, including a change in the same Group or Division and resulting in

      1. an increase in occupant load,

      2. a new occupancy other than the occupancies in Groups D and F,

      "Care. Personal assistance services may be required for some residents. Assistance services are intended to compensate for a temporary or permanent disability in order to provide for personal hygiene, feeding, grooming, the use of personal property, the movement or rehabilitation of a person, and services to supervise medication or manage a crisis, emergency or building evacuation situation.

      In a private seniors’ residence, assistance services include

      • personal assistance services such as

        • feeding, daily personal hygiene, dressing and bathing assistance services;

        • the care services involved in assistance with activities of daily living.

          Some services provided by a care facility are not care, including

    "A-4.2.5.8.(2) Backfilling. Certain granular material may swell under chemical reactions. A number of these reactions involve iron sulphide (pyrite, pyrrhotite, etc.) and carbonates present in the material and lead to the crystallization of sulfates and a subsequent increase in the volume of the granular backfill. The reactions are influenced by a number of factors, including the presence of clay minerals, which facilitate water absorption and the oxidation of iron sulphides, particle- size distribution, water content of materials, the presence of bacteria and temperature.

    The most prevalent characterization method for granular materials, the petrographic index for potential swelling, may be permitted for the purposes of meeting the requirement. The method is described in detail in the following documents:

    • NQ 2560-500, "Granulats - Détermination de l’indice pétrographique du potentiel de gonflement sulfatique des matériaux granulaires – Méthode d’essai pour l’évaluation de l’IPPG"

    • NQ 2560-510, "Granulats - Guide d’application de la méthode d’essai pour la caractérisation du potentiel de gonflement sulfatique des matériaux granulaires".

    The non-swelling rock accepted under the two standards is commonly called "DB certified rock" (DB for "dalle de béton".).

    Other methods, such as the chemically or biologically accelerated swelling test, may determine swelling but are less used because of the time required.

On the other hand, air entering a dwelling through below- grade leaks in the envelope may increase the water vapour content of the indoor air and may also bring in a number of pollutants which it picks up from the soil. This mixture of air, water vapour and pollutants is sometimes referred to as "soil gas". One pollutant often found in soil gas is radon.

    Radon is a colourless, odourless, radioactive gas that occurs naturally as a result of the decay of radium.

      There are two principal methods of excluding soil gas:

    • Sealing the interface between the soil and the occupied space, so far as is reasonably practicable. Sections 9.13. and 9.18. include requirements for soil gas barriers in crawl spaces. Providing control joints to reduce cracking of foundation walls and airtight covers for sump pits are other measures which can help achieve this objective. The requirements provided in Articles 9.13.4.3., 9.13.4.5., and 9.13.4.7. are described in Appendix Notes A- 9.13.4.3., 9.13.4.5. and 9.13.4.7., and A-9.13.4.5.(1) and (2).

    • Ensuring that the pressure difference across the soil/space interface is positive (i.e., towards the outside) so that inward soil gas flow through any remaining leaks will be prevented. The requirements provided in Article 9.13.4.6. are described in Appendix Note A-9.13.4.6.

For example, in 1998, the Oka region was formally identified by the Public Health Department as a zone with potential soil gas concentrations exceeding the prescribed toxicity level.

    A-9.13.4.1.(4) Subfloor Depressurization in Houses with Preserved Wood Foundations. Standard CAN/CSA-S406, "Construction of Preserved Wood Foundations", requires that a polyethylene sheet ground cover be installed under all floors-on-ground in buildings with preserved wood foundations. The use of a subfloor depressurization system may be acceptable with such constructions, seeing as the standard does not mention otherwise, but the polyethylene sheet ground cover is an unconditional requirement of that standard. The polyethylene sheet cannot be forfeited in houses intended to conform to the standard and the depressurization system would have to be installed under the ground cover membrane.

    A-9.13.4.3., 9.13.4.5. and 9.13.4.7. Soil Gas Barriers. The requirements provided in Article 9.13.4.3., Soil Gas Control in Walls, Article 9.13.4.5., Soil Gas Barriers, and Article 9.13.4.7, Sealing of the Perimeter and Penetrations, are illustrated in Figures A-9.13.4.3., 9.13.4.5. and 9.13.4.7.-A and A-9.13.4.3., 9.123.4.5. and 9.13.4.7.-B.

Floors-on-ground serving all types of occupancies other than garages must be constructed to reduce the potential for entry of radon or other soil gases. In most cases, this will be accomplished by placing 0.15 mm polyethylene under the floor.

    Finishing a concrete slab placed directly on polyethylene can, in many cases, cause problems for the inexperienced finisher. A rule of finishing, whether concrete is placed on polyethylene or not, is to never finish or "work" the surface of the slab while bleed water is present or before all the bleed water has risen to the surface and evaporated. If finishing operations are performed too early, such as before all the bleed water has risen and evaporated, surface defects such as blisters, crazing, scaling and dusting can result. This is often the case with slabs placed directly on polyethylene. The amount of bleed water that may come to the surface and the time required for this to happen is increased from that of a slab placed on a compacted granular base. The excess water

    in the mix from the bottom portion of the slab cannot bleed downward

    and out of the slab and be absorbed into the granular material below, because of the polyethylene. Therefore, all bleed water, includingB-t1h.1a,tr

    from the bottom of the slab, must now rise through the slab to the surface. Quite often in such cases, finishing operations are begun too

    soon and surface defects result.

    the polyethylene and the concrete. However, this is not an acceptable solution for the following reason: it is unlikely that the polyethylene will survive the slab pouring process entirely intact. Nevertheless, the polyethylene will still be effective in retarding the flow of soil gas if it is in intimate contact with the concrete; soil gas will only be able to penetrate where a break in the polyethylene coincides with a crack in the concrete. The majority of concrete cracks will probably be underlain by intact polyethylene. On the other hand, if there is an intervening layer of a porous medium, such as sand, soil gas will be able to travel laterally from a break in the polyethylene to the nearest crack in the concrete and the total system will be much less resistant to soil gas penetration.

    To reduce and/or control the cracking of concrete slabs, it is necessary to understand the nature and causes of volume changes of concrete and in particular those relating to drying shrinkage. The total amount of water in a mix is by far the largest contributor to the amount of drying shrinkage and resulting potential cracking that may be expected from a given concrete. The less total amount of water in the mix, the less volume change (due to evaporation of water), which means the less drying shrinkage that will occur. To lessen the volume change and potential cracking due to drying shrinkage, a mix with the lowest total amount of water that is practicable should always be used. To lower the water content of a mix, superplasticizers are often used to provide the needed workability of the concrete during the placing operation. High water/cementing materials ratio concretes usually have high water content mixes. They should be avoided to minimize drying shrinkage and cracking of the slab. The water/cementing materials ratio for slabs- on-ground should be no higher than 0.55.

    A-9.13.4.6. Soil Gas Control by Depressurization. As noted in Appendix Note A-9.13.4., one method of excluding soil gas from below- grade living space is to ensure that the pressure difference across the soil/space interface is positive (i.e., towards the outside) so that inward soil gas flow through any leaks will be prevented. This requires consideration of the air pressure on the inside of the envelope and the pressure within the soil. Each is affected by quite different factors.

    There is a safe range for the interior pressure in a house. The upper limit is primarily due to the need to minimize outward leakage of the warm, moist interior air through leaks in the building envelope. The lower limit depends on the type of combustion heating equipment present in the house, as discussed in Appendix Note A-9.33.1.1.(2). It also follows from the need to avoid drawing in soil gas, as discussed in Appendix Note A-9.13.4.

    Controlling the entry of soil gas by house or basement pressurization is therefore problematic, since it could lead to exfiltration-caused condensation problems in the building envelope. This leaves the option of reducing the pressure outside the envelope as the most practicable method of achieving the desired outward pressure difference.

    Subfloor depressurization systems have been found to be very effective for controlling soil gas entry into houses. At least in areas which are

    excessive.

    Radon testing must be performed on the house and copies of the results provided to the home owner and the authority having jurisdiction. Since the radon level in a house can vary significantly during the year, the test should be of sufficient duration to provide a reasonable indication of the concentration.

    The minimum period for testing should be three months or as recommended by the authority having jurisdiction. The preferred testing location is centrally in the basement or the main floor for houses without basements. In addition, the owner should be informed that testing should be repeated subsequently as radon concentrations may vary over the years even if the result of the initial testing is lower than the recommended limit.

    The current Canadian Action Level for radon, as specified by Health Canada, is 800 Bq/m3 (see H46-2/90-156E, "Exposure Guidelines for Residential Indoor Air Quality"). If the results of the test indicate a concentration exceeding the Canadian Action Level, the rest of the sub- slab depressurization system must be installed. (It may be noted that Canadian action levels are likely to be inferior.)

    Installation of the sub-slab depressurization system requires that the pipe cast through the slab to the sub-slab space be uncapped and connected to a ventilation system exhausting to the outside. Exhaust pipes passing through unheated spaces should be insulated. The exhaust fan should be located outside the occupied space where noise will not be a nuisance. It is also best to locate the fan as close to the final outlet end of the ventilation system as possible so that the pressurized portion of the system downstream of the fan will not be located in or adjacent to the living space. If the pressurized portion of the system were to pass through the living space, then any leak in the system would have the potential to spill high concentration soil gas into the living space, thus exacerbating the situation the system was intended to correct. The fan should be of a type suitable for the application and capable of continuous operation.

    Since radon concentration of the vent gases can become quite high, soil gases collected by the sub-slab depressurization system should be vented at the roof level. Therefore, it may be desirable to take some simple steps to facilitate future installation of the system. This could include locating the slab vent pipe below a suitable interior partition, through which the vertical riser could be run, and pre-drilling the partition top and bottom plates, particularly those not accessible from a basement or attic.

    The house should be re-tested for radon after completion of the depressurization system.

    This provision refers to an alteration, other than a minor alteration, that does not include an exit.

    A-10.3.4.4. Exit Signs. The purpose of this Article is to permit the use of exit signs consisting of the letters "SORTIE" or "EXIT" in red or white on a contrasting red or white background in existing buildings even during alteration work. However, if during the course of the alteration work, the owner or his or her representative decides to use the green pictogram to identify an exit in a floor area, all of the exits signs in that floor area must be of the same type. Exit signs located inside individual suites in the floor must also be replaced, along with those located in an interconnected floor space or a mezzanine leading to that floor area. It is thus permitted to have two different types of exit signs in the same building but not in the same floor area.

    Where the alteration work includes adding an exit in the building, all of the exit signs in the floor area(s) under alteration must conform to the requirements of Sentence 3.4.5.1.(2) or 9.9.11.3.(2) because the alteration work involves the addition of an exit and not its replacement.

    "Annual energy consumption" means the annual sum of heating energy consumption and space conditioning energy consumption of the proposed construction design. It must be noted that the annual energy consumption is not the real consumption, but rather that provided by energy simulation.

    The calculation procedure must determine the annual energy consumption for the proposed construction and a construction energy target for a reference construction. The annual energy consumption of the proposed construction must not exceed the construction energy target of the reference construction. Proof of those results must be available on request.

    If a computer program is used to carry out the compliance calculations, the calculation methods shall be computed for both the referenced and the proposed construction models, and be tested according to ASHRAE 140, "Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs", and variations in the computer program results from the different recommended values must be calculated.

    Where construction techniques or components used for construction are more energy efficient than those prescribed by the prescriptive requirements, performance compliance calculations are permitted to take this increased performance level into account in the determination of the annual energy consumption, provided the consumption can be quantified and is not dependent on occupant interaction.

    The energy model calculations must account for the annual energy consumption of systems and equipment required for space heating and conditioning and for ventilation. The energy model calculations must account for heat transfer through wall assemblies, roof-ceiling assemblies and exposed floor assemblies due to the thermal characteristics of the particular assembly and thermal bridging. The roof- ceiling assembly includes the attic. The building envelope assemblies and components required to be addressed in the calculations are assemblies above and not in contact with the ground (walls and roof- ceiling assemblies), assemblies in contact with the ground (floors and walls), and doors, windows and skylights.

    Where the energy model calculations account for the effect of thermal mass, that thermal mass must exclude the contents of the construction.

    Where skylights are installed in the roof, the gross roof area does not exclude the gross roof area of skylights.

    The calculation procedure for the reference construction must include the same values as those used for the proposed construction with regards to the floor area, the heated volume, and the number and type of rooms.
