Integrated Sustainable Approach

Sustainability has been a key consideration right from the initial concept with the early engagement and participation of key team members including the Mechanical Engineer, Energy Modeler and Sustainability Project Manger. Sustainability will continue to be a focal point throughout design and construction with the ultimate goal of providing a long lasting sustainable community for people to live and work.

The next phase of design will include the engagement of BC Hydro and participation in their New Construction Program. The mandate of the program includes resources and technical assistance to developers and the design community to create high-performance, energy efficient buildings. The project team will continue to utilize resources such as the BC Hydro New Construction Program to help further optimize the passive and active strategies of the development.

Transportation:

The project will have a strong focus on alternative transportation from alternative fuel vehicles charging stations and co-op vehicles. Pedestrian opportunities for living and working downtown will be maximized by providing significant infrastructure for bicycle storage, public access, and smart location close to multiple bus routes and walking distance to many amenities within the downtown core.

Key Features:

• LEED-NC 2009 Gold Targeted

• Strategic location adjacent to multiple transit routes and City Bike Network

• Passive Architectural Strategies to reduce Heating and Cooling Loads

• Individual façade treatments per solar exposure

• Building envelope design with focus on energy conservation

• Energy Sharing through Heat Recovery

• Significant reduction in storm water runoff

• Green Roofs and Urban Agriculture including the use of native and adaptive vegetation

• Domestic potable water reduction through efficient fixtures

• Significant use of local manufactured materials

• Extensive diversion of construction waste through a Construction Waste Management Plan

• Retention of Toyota Dealership downtown reduces car trips out of town for vehicle servicing

NATURAL VENTILATION & COOLING THROUGH STACK EFFECT

DAYLIGHTING FROM GLASS & INTERNAL ATRIUM

LEANING GLASS REDUCES SOLAR ANGLE OF INCIDENT

GREEN ROOF

The Toyota Dealership

The three storey Toyota Dealership will use a central elliptical atrium configured to create the opportunity for natural ventilation. Warm air will be passively drawn from the sales floors to the roof through stack effect; while also increasing daylight to the central darker regions of the plan below. The outward leaning form of its curtain wall façade will reduce solar heat gain and reduce the reliance on interior back-lighting as the leaning glass will increase visibility from the street. The design team is investigating additional strategies to decrease solar heat gains such as external shading devices and glass fritting. On the roof we propose an active area with significant greenery, which will cool the roof and shade the atrium skylight.

The Office Building

Facade Design

The West & East façades of the Office feature a decorative frit pattern imbedded into the glass. This lace motif will decrease solar heat gain while retaining maximum view out. The South façade has louvers on every floor slab.

Daylighting

12’ clear floors with floor to ceiling glazing and a relatively shallow office floor plate will allow daylight to enter all parts of the building. The narrow footplates will also create a sense of connection to the external environment, creating a more livable and workable environment.

Heating & Cooling

We will be exploring the use of Geo-exchange Fields tostore heat under the buildings, an energy highway totransfer waste heat from air conditioning to buildingheating and domestic hot water systems, heat recoveryfrom the office ceiling plenum, heat recovery fromrestaurant/automotive/office exhausts, solar heatingpanels, heat recovery from sewage, variable speeddrives on all major heating and cooling systems,19 SEER air conditioning units and natural ventilation for cooling of atrium and high ceiling areas. Key energy concepts will be confirmed through detailed energy modeling through the BC Hydro New Construction Program.

Green Roof

A green roof will cover a percentage of the main mechanical level, with a large canopy to further shade the roof activities and decrease its overall albedo and heat island effect. The green roof will also be a key component in reducing the developments impact on local storm sewer infrastructure by significantly reducing stormwater runoff compared to existing conditions. The green roofs and accessible areas will also create a retreat within the development; a place where the residents and office employees can enjoy breaks away from the noise and bustling city life around the development.

The Towers

The showroom at grade of Tower A will be for Toyota’s new Sub-compact brand – Scion, a compact fuel-efficient vehicle. From the lane a surface parking zone will be retained, in Tower C; containing 16 Toyota fuel efficient vehicles for the project’s Car Share program.

The outward leaning façade will decrease solar heat gain, and a green roof with low albedo surface materials will decrease heat island effect and interior heat gain. To provide shade from the heat intensive western sun path and further reduce solar heat gain, the South Façade will be equipped with large horizontal overhangs; the East and West feature façade will be configured in a staggered grid, and the organic pattern will also provide an opportunity to decrease the elevations’ overall quantity of glazing. Conversely the lower units gain the benefit of increased privacy by the smaller quantity of vision area. This punched façade will also act as a heat sink, drawing in heat during the day and releasing it to the interior during the night.

Overall we see this as a “whole” development, which will provide a place to live, work and play. Residents, guests & workers can use the Hotel facilities, Daycare, and amenities. By having such an extensive mixed-use development, the overall number of car trips can be greatly reduced in the City, decreasing congestion and increasing the standard of living for both those within the building and the surrounding neighbourhood.
