SUSTAINABILITY STRATEGIES

AN INTEGRATED APPROACH

The development at 1445 & 1455 West Georgia St. aims to be a deep green, resilient project within the context of its typology as an urban residential high rise. The development strives for a holistic approach putting the environment and people at the forefront of design. The project will be designed for LEED Gold and a minimum of 63 points under LEED Canada NC 2009 and compliance with VBBL 2014, including the Green Buildings Policy for Rezoning, General Policy for Higher Buildings, and required energy targets. Refer to Appendix for LEED scorecard for more detail.

The project has taken action towards finding opportunity for innovation within the constraints of its typology and urban location. Through an integrated design process including sustainability workshops and design team feedback, each design discipline, architectural, electrical, mechanical, structural and landscape design, has come up with ideas to incorporate measures beyond the norm for this Residential project on a unique site in Vancouver. The ideas strive to be holistic in nature with multifaceted sustainability benefits for both the project and the public realm.

There are five key sustainability strategies classified under the following categories:

ENVIRONMENT

• Energy Efficiency & Low Carbon Design• Sustainable Use of Land & Water• A Healthy Indoor Environment

SOCIAL SUSTAINABILITY

• Community & Social Connectivity

DESIGN INNOVATION

• Green Building Design Innovation

SUSTAINABILITY STRATEGIES

SUSTAINABILITY STRATEGIES

ENERGY EFFICIENCY & LOW CARBON DESIGN

The building will be designed with optimal energy efficiency and greenhouse gas reduction emissions as a key focus using an integrated systems approach. The system design will focus on firstly reducing loads, secondly harvesting heat from processes in the building to use for heating elsewhere, and lastly selecting efficient equipment to reduce all power and heating loads associated with equipment operation.

OPTIMIZED ENVELOPE DESIGN• Reduce window to wall ratio: Reduced vision wall glazing compared to typical market practice• Glazing thermal performance: Triple pane glazing will be investigated with thermally broken frames for acoustic

protection from traffic noise, improved thermal comfort, and improved energy performance• Minimize thermal bridging: Insulated balconies to minimize thermal bridging for energy and occupant comfort• Micro-climate: South and northwest façades will have deep balconies for solar shading. South facing balconies

have additional vertical sun screens for occupants’ solar shading and improved microclimate. Screens may be moveable to address individual comfort needs

EFFICIENT LIGHTING SYSTEM• Reduced lighting power: Efficient LED lighting fixtures will be used to significantly reduce the power load• Parkade lighting: Efficient controls with occupancy sensors and dimmable lighting to reduce lighting power and ensure safety• Minimize light pollution: Exterior lighting will be designed with efficient fixtures selected to minimize urban light pollution

EFFECTIVE MECHANICAL SYSTEM• Low carbon district heating: The building will be connected to the Neighborhood Energy Utility (NEU) • Efficient heating and cooling: The building heating system will be a low-temperature hydronic heating system with

high-efficiency pumps. Building cooling will be provided though central heat recovery chillers that can recover heat at times of simultaneous heating and cooling

• Maximize heat recovery: high efficiency heat recovery on building ventilation will reduce heating load

CARBON NEUTRALITY• Renewable energy: strategies will be investigated such as roof-mounted photovoltaics or solar thermal panels• Embodied carbon: fly-ash will be used in all concrete structures where curing time allows to offset energy and

embodied carbon intensive cement ratios. Recycled steel will be investigated for all end-uses

RAINWATER HARVESTING: WATER WILL BE COLLECTED DIRECTLY FROM

THE SLOPED CURTAINWALL RUN-OFF

HEALTHY TRANSPORTATION: EXISTING PUBLIC TRANSIT/BIKE NETWORK,

AND PROVIDE WEATHER-PROTECTED RACKS

EFFECTIVE LANDSCAPING:USE OF ADAPTIVE/NATIVE PLANTS

FOR SUSTAINABLE USE OF WATER

URBAN ROOM: SOCIAL CONNECTION

COMMUNITY & SOCIAL CONNECTIVITY

HEALTHY INDOOR ENVIRONMENT

Human health and wellbeing will be strategically addressed through various design solutions for the project.• Enhanced acoustic design: Acoustic comfort will be addressed through the appropriate selection of materials and

the investigation into triple glazed windows reducing ambient noise • Providing access to daylight and views: Daylight and views will be maximized for human health and wellbeing• Healthy materials selection: Low emitting finishes will help provide healthy indoor air quality• Improved indoor air quality: Use of particle control from dust through the use of vestibules and dirt remediation strategies

SUSTAINABILITY STRATEGIES

SUSTAINABILITY STRATEGIES

The project will take advantage of the sustainable infrastructure of the surrounding area and give back to the community through means of open space, added green space and site transparency • Public transit access: The location of the project is on an existing active transportation and bike network • Foster healthy transit: There will be a resident’s Bike Pump Room next to the Bicycle Storage Room, as well as

weather-protected bike racks, for non-residents, at the arrival area to support active modes of transportation• Carbon neutral vehicles: Electrical vehicle charging outlets will be provided for 20% of the total vehicle parking

capacity of the site for residential, per VBBL• Biophilic design elements: Integration of nature and natural processes through a falling water feature that will be

implemented on site with possible use of harvested rainwater and the use of natural materials

SUSTAINABLE USE OF LAND & WATER

Strategies for efficient potable water use reduction will be implemented in combination with rainwater harvesting, stormwater mitigation and efficient landscape design. • Stormwater management: Quality and quantity control measures will be implemented on site. Stormwater is collected,

by gravity wherever possible, to centralized storage where it is filtered and discharged to the City’s storm system• Potable water reduction: Targeting 35% will be achieved through selection of durable and efficient plumbing fixtures• Rainwater harvesting: Rainwater will be collected directly from the sloped curtainwall run-off, and will offset all

irrigation needs subject to approval of an engineered treatment system. If possible, the rainwater will be directly used for irrigation instead of passing through the centralized storage

• Effective landscaping: The use of adaptive and/or native species will be considered in design such that no potable water is required for irrigation.

GREEN BUILDING DESIGN INNOVATION

As part of this integrated process, the project team is approaching innovation strategies fostering forward thinking ideas in support of sustainability strategies for the project.

• Regeneration of open space: The elevated Tower floors, 80 FT above street level, allows an outdoor Urban Room under the tower, regenerating public green space for the greater community by adding accessible open area to the existing urban site, in keeping with the General Policy for Higher Buildings

• Unique seismic design: An extraordinary seismic analysis in collaboration with UBC will be completed - being the first of its kind in Canada to date

• Thermal pollution reduction: Recovery of thermal heat while improving occupant comfort both interior and exterior will be investigated as part a Thermal Pollution Reduction strategy

• Life-cycle assessment: An embodied carbon analysis will assess the impact from the project’s structural components and carbon neutral materials will be implemented to better understand carbon footprint

• Circadian lighting design: Will be part of the residential suite lighting strategy for improved occupant long-term health & wellbeing

• No mercury: Complete elimination of mercury containing lamps to minimize toxic waste
