SUSTAINABILITY MEASURES

Transcription

1 The following items summarize our strategies to outperform the City of Vancouver s sustainability requirements with focus on reducing the thermal energy demand, total energy use, and greenhouse gas emissions of the building and achieving significant leadership goals in this project: Building Shape: The current building geometry with Vertical to Floor Area Ratio (VFAR) of 0.5 represents a compact design that contributes to thermal demand and energy reduction of the building. Efficient Solar Shading: Utilization of distributed balconies and vertical fins allows for desirable low-angle solar gain in Winter and blocks undesirable high-angle Summer solar gain in the building. High Efficiency Glazing: Utilization of high-performance triple pane glazing with low-e coating allows for maximum utilization of daylight and balance between desirable Winter solar gain and undesirable Summer solar blockage leading to reduction in overall building energy consumption. The maximum share of glazing is distributed on the South Elevation of the building to further contribute to solar gain and daylight utilization in the building. High Thermal Efficiency and Air Tight Building Envelope System: Utilization of exterior insulated walls, high efficiency spandrel system, thermally broken balconies, high level of detailing at all building envelope interfaces, and air barrier commissioning throughout design and construction phases lead to significant reduction of undesirable heat and mass exchange between the building and ambient. High Efficiency Heat Recovery Ventilators (HRVs): High efficiency HRVs are utilized at each residential unit, amenity space, and commercial unit to provide appropriate direct ventilation and reduce energy demand for conditioning of fresh air supplied to the building spaces. High Efficiency Central Heat Pump for Heating and Cooling: Heating and cooling is provided by 4-pipe fancoil system connected to high efficiency central air source heat pump for residential and commercial units, and amenity areas. High Efficiency Central Cascade Heat Pump for Service Water Heating: Central high efficiency cascade air and water source heat pump system is utilized for domestic water heating system that leads to significant reduction in building energy consumption and GHG emissions. Low Emitting Materials in Building Construction: Utilization of low emitting materials is a key factor of this building development that will be ensured through design and construction phases by the entire project team. Integrated Rainwater Management and Green Infrastructure: An appropriate treatment and safe conveyance of rain water as well as utilization of green areas are considered in the site design to enhance resilience and sustainability in the development and contribute to nature conservancy. September 18, 2018 City of Vancouver Planning, Urban Design and Sustainability West Annex, 515 West 10 th Ave Vancouver, BC V5Y 1V4 Attn: Development Planner SUBJECT: LOW EMISSIONS GREEN BUILDINGS - (SDS) DEVELOPMENT BY: PINNACLE INTERNATIONAL ADDRESS: 601 BEACH CRESCENT, VANCOUVER BC Building Science (BCBS) was retained by Pinnacle International as Building Envelope and Energy Consultant for the above noted new development. As part of the design development, we are providing a strategy for consideration in meeting the relevant requirements of the City of Vancouver Green Building Policy for Rezoning (CoV-GBPR). The primary intent of this letter is to establish a proposed strategy related to architectural, landscape, building science, mechanical, and electrical designs of the building towards achieving the sustainability aspects of the Low Emissions Green Buildings - Sections B.1 to B.11 compliance path as per CoV-GBPR. The following summarizes the proposed sustainable design strategy (SDS) that includes project-specific approaches confirming how the design meets each sustainability requirement of the CoV-GBPR. B.1 Leadership in Energy and Environmental Design This requirement is not applicable to the project due to more than 50% residential usage of the building. B.2 Performance Limits A preliminary Zero Emissions Building Plan (ZEBP) Energy Checklist and a summary of detailed energy model input prepared by BCBS are attached to the Rezoning Application. Based on our early stage communications and meeting with the CoV-Sustainability Group on May 1 st, 2018, this project is required to achieve Leadership on Thermal Energy Demand Intensity (TEDI) and Greenhouse Gas Intensity (GHGI) beyond the performance limits of CoV-GBPR. As such, the design team aimed to meet a TEDI of 22 [kwh/y/m 2 ] and GHGI of 3 [kgco2/y/m 2 ]. Details of the design aspects and achieved indicators are provided in the ZEBP Checklist and summary of energy model input attached to the Rezoning Application. The following represent strategies taken in this project to outperform the CoV-GBPR limits of TEDI, TEUI, and GHGI as leadership demonstration in this project: - Compact architectural design of the tower and podium with VFAR of Summer solar gain reduction from distributed balconies at each floor of tower - High exterior-insulated steel framing walls (5 ext. mineral wool) - High efficiency curtain wall spandrel system [18032_601 BEACH_1.09] 25

2 Pinnacle 601 Beach Crescent, Vancouver September 18, 2018, Page 2/5 - High performance triple glazed curtain wall windows with low-e coating - Thermally broken balconies with exterior insulated curbs - Efficient detailing at all envelope interfaces - Air tight building design, 1.0 L/s/m 75 Pa - High efficiency local HRV with SRE 78% for all residential and commercial units, and common areas (other than corridors) - Heating and cooling by 4-pipe fancoil system connected to high efficiency central air source heat pump for residential and commercial units, and common areas (other than corridors) - Central high efficiency cascade air and water source heat pump system for domestic water heating equipped with electric resistance backup B.3 Whole Building Airtightness Testing BCBS will perform air barrier commissioning through design and construction phases. The intent is to achieve an air leakage target of 1.0 L/s/m 75 Pa for whole building, which is beyond the rezoning requirement for building air tightness. This leadership in air tightness achievement is dictated by the energy modelling results for meeting the stringent TEDI target in this project. The air barrier commissioning through the design phase will include design review of architectural drawings specific to the air barrier by BCBS team to ensure continuity of the air barrier. BCBS will also perform field reviews through construction phase specific to air barrier installation. Further, sample suites will be pre-tested for air tightness during construction phase. BCBS will also perform whole building and suite air tightness tests based on ASTM E779 after construction that includes providing blower doors and associated equipment and executing the test. B.4 Enhanced Commissioning Pinnacle 601 Beach Crescent, Vancouver September 18, 2018, Page 3/ Energy Reporting BCBS will assist the Owner in setting up an EnergyStar Portfolio Manager account. BCBS will further assist the Owner to hire a qualified service provider for annual energy benchmarking report to the City for a period of at least three years after occupancy. B.6 Calculating Refrigerant and Embodied Emissions 6.1. Refrigerant Emissions BCBS will perform calculation and report the life-cycle equivalent annual carbon dioxide emissions of building from the refrigerants in kgco2e/m 2. BCBS will acquire type and capacity of refrigerants in all the installed cooling and heating equipment containing refrigerants in the building in collaboration with the Mechanical consultant and will perform and document the related calculations Embodied Emissions BCBS calculates and reports embodied emissions from all envelope and structural elements using the Canadianbased Athena Impact Estimator as whole-building life-cycle assessment (LCA) software tool. The results specify the life-cycle equivalent carbon dioxide emissions [kgco2e] in addition to embodied emissions intensity [kgco2e/m 2 ] and annual embodied emissions intensity [kgco2e/m 2 /year]. A preliminary embodied emission calculation at this rezoning stage follows. The preliminary embodied emissions from building envelope and structural materials are calculated based on the following preliminary quantity take-offs. Because the detailed structural design of the building is not available at this rezoning application stage, typical building structure components are assumed based on similar projects. BCBS will complete enhanced commissioning for all energy systems in the building in accordance with ASHRAE Guideline and ASHRAE Guideline BCBS will prepare the Owner s Project Requirements (OPR) and Basis of Design (BOD) with respect to a sustainable energy design and all applicable green building policies. BCBS has been on project design board since the beginning of project and taking lead on energy consultation to direct design of all energy systems in the building for high performance achievement. BCBS will develop the project commissioning plan in collaboration with the Mechanical and Electrical design teams. BCBS will develop commissioning report throughout the project based on the commissioning plan and by performing 1) design reviews of energy systems during design and construction phases with respect to energy efficiency, 2) field reviews of energy systems during construction, 3) energy efficiency test and documentation during and at the end of construction, and 4) reviewing the training record/documents and O&M manuals prepared by mechanical and electrical contractors. B.5 Energy System Sub-Metering and Reporting 5.1.

Lifecycle Embodied Emissions 2.21E+07 kgco2e B.11 Resilient Drinking Water Access Embodied Emissions Intensity kgco2e/m 2 Annual Embodied Emissions Intensity 7.94 kgco2e/m 2 /year The preliminary results will be updated by BCBS at the Building Permit Application Stage using the completed architectural, building envelope, and structural designs. B.7 Verified Direct Ventilation Along with enhanced commissioning of energy systems in the building, BCBS will also commission the building ventilation system through design and installation phases with respect to direct ventilation requirement of the CoV-GBPR based on VBBL 2014 and ASHRAE 62 standard. BCBS will coordinate with the Architect, Landscape, and/or Mechanical consultants, perform design and field review to ensure that enough drinking water fixtures capable of operating on city water pressure with no electricity requirement are provided and easily accessible for occupants in the building as per CoV-GBPR. Please contact the undersigned if there are any questions. Respectfully Submitted, Farshid Bagheri, PhD, PEng Based on energy model results reported by BCBS, all residential and common areas in the building (other than corridors) will be equipped with heat recovery ventilators that provide direct ventilation to the occupied areas. All corridors will also be directly ventilated by a central make-up air unit beyond ASHRAE 62 for pressurization to avoid odour and small transfer between residential suites. BCBS will work with the Mechanical consultant, perform design reviews of ventilation system during design and construction phases, and perform field reviews and tests of ventilation supply and exhaust during and at the end of construction phase to ensure and verify that direct ventilation is supplied to all occupiable areas in the building. B.8 Low Emitting Materials Design and construction of the building with acceptable low emitting materials is within the scope of most consultants in the project. BCBS will coordinate with other consultants to ensure all requirements for low emitting materials of CoV-GBPR are met. It will be ensured that urea-formaldehyde resins are not used at all and the emissions from interior materials containing volatile organic compounds (VOCs) or added urea formaldehyde are minimized by meeting the content requirements of Green Seal, Green Label, Green Label Plus, FloorScore, or South Coast Air Quality Management District (SCAQMD) Rules. B.9 Indoor Air Quality Testing BCBS will coordinate indoor air quality testing for formaldehyde, particulates, ozone, total volatile organic compounds, and carbon monoxide prior to occupancy, and report results to the City as compared to acceptable target concentration levels and standards listed in the CoV-GBPR. Our strategy to meet the maximum concentration limit of contaminants in the building is reflected in: 1) perform design and field reviews to ensure appropriate direct ventilation is provided to all occupiable areas, 2) coordinate with other consultants to minimize utilization of emitting materials such as volatile organic compounds and urea formaldehyde in the building design and construction. B.10 Integrated Rainwater Management and Green Infrastructure The utilization of Integrated Rainwater Management and Green Infrastructure in the project are within the scope of Civil consultant. The design team will ensure that appropriate treatment and safe conveyance of rain water are considered in the site design and all related measures are aligned with the City-Wide Integrated Rainwater Management Plan (IRMP) requirements. 27
