Energy Trigger (A Existing Building Upgrade Mechanism Model)

Transcription

1 Trigger (A Existing Building Upgrade Mechanism Model) Applicability All Building Permit applications for projects related to existing buildings are required to follow the energy upgrade trigger process with the following exceptions; i) Buildings categorized as; i. 1 and 2 Family Dwellings, or ii. Temporary Building/Use (< 1 year) ii) iii) Buildings designed and constructed to; i. ASHRAE , or ii. ASHRAE , or iii. NECB 2011 Projects categorized as; i. Interior Demolition: Scope of work is limited to interior alterations involving removal of non-load bearing walls, fixed millwork and related electrical/plumbing so that the space reverts back to a shell state that is not occupied. Future tenant improvement work and building permit will be required for occupancy of this space at which time Part 11 energy upgrades will be triggered. ii. Subdividing Existing Commercial Space: Scope of work of an existing office or retail space is being subdivided into small units. A new space is created as an empty (shell) space that is not occupied. Future tenant improvement work and building permit will be required for occupancy of this space at which time Part 11 energy upgrades will be triggered. iii. Repair (Fire, Flood, Leak): Scope of work is different from "Repair" under Part 11's Flow Chart No.1 which is based on normal operation's wear and tear. This Repair work can be due to fire, flood, water leak, etc. where additional work triggered by Part 11 may be onerous and not covered by insurance. iv. Re and Re Work (Remove and Replace): Scope of work is limited to the removal and replacement of existing appliance(s) or plumbing fixtures, typically within condominiums. Work comprises of replacing a tub, basin, kitchen sink, etc. but does not involve alterations to interior walls. However, renovations or overhauling of kitchen or washroom is not considered Re and Re Work. v. Minor Alterations: Scope of work is deemed as very minor, such as installing hand/mop sink to meet Health Department requirements. Acceptance of exemption under this category is at the discretion of the CBO, or the CBO's representative. vi. Site / External Alterations: Scope of work is outside the building envelope and independent of the building s operations. Examples include site work, canopy or awning installation, drainage, and surface parking lot work including parking lot/parkade kiosk upgrades.

2 Voluntary Upgrade ( Criteria) The Voluntary Upgrade option is applicable when the entire scope of work consists of the upgrading of energy related equipment and/or components as listed below. Any additional work not directly related to the upgrading of energy related equipment and/or components, negates the Voluntary Upgrade option. The intent of the Voluntary Upgrade exemption is to allow buildings to voluntarily upgrade energy related equipment or components without triggering additional upgrade requirements in any of the trigger categories. Certain conditions apply. i) All energy related equipment being replaced must be replaced with either; a) a more efficient model recognised in its class as high efficiency, or b) the most efficient model. ii) Equipment: All energy related components being replaced must be replaced with components that meet or exceed present Vancouver Building By-Law requirements. The addition or replacement of any of the following energy related equipment is eligible for the Voluntary Upgrade exemption; Boilers, Furnaces, Hot Water Tanks, Motors (including variable speed) Lighting Systems, Reduction Sensors (occupancy sensors, day-lighting sensors, etc.) Renewable Systems Photovoltaic system Solar Thermal system Biofuel-based system Geothermal Heating system Geothermal Electric system Wave & Tidal Power system High Performance Systems Ground Source Heat Pump system Air Source Heat Pump system Waste Heat Recovery system Components: The addition or replacement of any of the following energy related components are eligible for the Voluntary Upgrade exemption; Any component of a building s envelope

3 PROJECT TYPES AND THEIR RELATED CATEGORIES OF WORK REHABILITATION PROJECT TYPE (Flow Chart No. 1) REPAIR Repair pertains to a limited scope of interior or exterior renovation work to replace existing building components with functionally equivalent components. Repair work may not include work that increases the usable floor area of a building, creates an interconnected floor space, supports an addition or change of use, or the consolidation of more than one existing suite into a single tenant space. If the renovation includes other categories of work or project types such as a change of major occupancy classification or an addition, then the most restrictive upgrade levels from all project types would be applied. For Repairs, an E1 level of energy upgrade shall be applied. SMALL SUITE The upgrade trigger Small Suite pertains to limited renovation work within a small suite as defined in Division A, Article Small Suite work may include reconfiguration of the interior space of the suite, but may not include work on more than level (storey or mezzanine), interconnected floor spaces, exterior renovations, or the consolidation of more than one existing suite into a single new tenant space. If the renovation includes other categories of work or project types such as a change of major occupancy classification or an addition, then the most restrictive upgrade levels from all project types would be applied. For Small suite renovations, an E2 level of energy upgrade shall be applied. MINOR RENOVATION Minor renovations mean work within a single tenant space which may occupy multiple levels in a building. Minor renovations may include reconfiguration of the interior space of the suite as well as exterior renovations or the consolidation of more than one existing suite into a single new tenant space; however, a change of major occupancy classification is not considered to be a minor renovation type project. Where the renovation includes a new interconnected floor space or a new mezzanine, this work would not be considered to be a minor renovation. New mezzanines are considered to be additions. If the renovation includes other categories of work or project types such as a change of major occupancy classification or an addition (mezzanine), then the most restrictive upgrade levels from all project types would be applied. MAJOR RENOVATION Major renovations means work which may include (singly or in combination): Interior re-configuration of multiple tenant spaces, interconnected floor spaces, exterior alterations, or alterations that create more than one new tenant space. However, where such renovation includes a change of major occupancy classification or a new mezzanine, this work would not be considered as a major renovation. New mezzanines are considered to be additions. If the renovation includes other categories of work or project types such as a change of major occupancy classification or an addition (mezzanine) then the most restrictive upgrade levels from all project types would be applied. RECONSTRUCTION - Reconstruction means any project where: extensive renovations are being carried on throughout the entire building and the building is completely gutted; where all drywall and plaster has been removed from the interior walls; all drywall, plaster, insulation and exterior cladding has been removed from the exterior walls ; and all floor and roof membranes and coverings have been removed. Reconstruction also includes substantial reconfiguration of the interior floor space. Reconstruction means exposing the primary structure of the building on all interior and exterior walls, floors and roof with only the primary structural elements remaining in place (the building skeleton). Where work which might otherwise be considered as reconstruction, is undertaken solely to facilitate the repair of a building due to envelope damage, insect infestation, mould abatement or asbestos abatement, then the work would not be considered a reconstruction: it would be considered a repair, minor renovation or a major renovation as defined in this By-law.

5 CHANGE OF MAJOR OCCUPANCY CLASSIFICATION PROJECTS (Flow Chart No. 2) Change of Major Occupancy Classification Change of major occupancy classification means a change of use within a building, a suite, or its constituent floor areas where the proposed use is outside of the defined uses of the existing major occupancy classification permitted for the building, the suite, or its constituent floor areas. Small Suite Change of Major Occupancy Classification Small suite change of major occupancy classification means a change of use within a small suite, or its constituent floor areas where the occupant load for the entire suite does not exceed 60 persons and the small suite is limited to a Group A, Division 2, Group D, Group E, Group F, Division 2 (wholesale showroom), or Group F, Division 3 major occupancy.

6 ADDITION PROJECTS (Flow Chart No. 3) Horizontal Horizontal additions include both minor and major horizontal additions. A minor horizontal addition is any expansion of a floor area beyond the extents of the existing floor area in which it is located by not more than 25 per cent of the existing building area, or by not more than 500 m 2 in aggregate floor area. A major horizontal is any expansion of a floor area beyond the extents of the existing floor area in which it is located by more than 25 per cent of the existing building area, or by more than 500 m 2 in aggregate floor area. Any construction creates new floor area that in-fills existing roof or deck areas, or is superimposed over existing building structure or floor area is not considered a horizontal addition. Vertical Vertical additions include both minor and major vertical additions. A minor vertical addition is the addition of new floor area (storey or mezzanine) that in-fills existing roof or deck areas, or is superimposed over existing building structure or floor area, with an aggregate floor area increase of not more than 25 per cent of the building area, or by not more than 500 m 2 in aggregate building area. A major vertical addition is an addition that increases the aggregate floor areas or mezzanine area increase of not more than 25 per cent of the existing building area or increases the total aggregate floor area by more than 500 m 2.
