We enjoy working with a diverse group of stakeholders, which include the client, user groups, students and faculty. Two project examples in which B+H BuntingCoady worked with Kwantlen University include Kwantlen Polytechnic University Administration Building ‘C’ and Kwantlen Polytechnic Library Building ‘A’. Kwantlen Polytechnic University Administration Building ‘C’: The new Administration Building for Kwantlen Polytechnic University in Surrey (C2) provides this campus with a unique and contemporary ‘front door’ through which to welcome and orient students and visitors. The entrance features a dramatic canopy with copper ringed oculus and wood soffit while the light-filled three storey atrium bridges the gap between the old and the new buildings. Bunting Coady Architect’s Integrated Design Process was used throughout to shape the building, coordinate flexible modular internal layouts and enhance the progressive sustainable building mandate. This striking facility is designed to LEED® Gold. Sustainable Building Challenge- iiSBE Canada SB11 Call for Poster Presentations LIBRARY BUILDING ‘A’ Kwantlen Polytechnic Library Building ‘A’: Kwantlen Polytechnic Library Building ‘A’ is at the very heart of the Kwantlen Polytechnic University Surrey Campus. The two storey entrance and library renovation is the focal point of the interior quadrangle, providing a light, well ventilated space, dedicated to the pursuit of learning. The second floor of the revitalized glazed lobby provides a quiet, daylight filled, contemplative setting for private reading, while the versatile three storey south wing provides learning labs for interactive teaching, along with additional individual and group study areas. Over 90% of all occupied spaces within this facility have views to the outdoors, to provide direct connectivity to the environment. This durable, flexible and efficient library is targeted LEED® Platinum and incorporates a wealth of sustainable design features to significantly reduce environmental impact. Indoor air standards within the Kwantlen Library go well beyond the required provincial nonsmoking requirement. Air systems are protected by gateway grills designed to capture dirt and particulates. Carbon dioxide monitoring systems have also been incorporated throughout the building, to detect elevated levels and increase fresh air to the building. No chlorofluorocarbons (CFC’s), Halons or HCFC’s were used in the facility, although current legislation permits the use of HCFC’s in the USA and Canada until 2030. Only non- or low-VOC (volatile organic compound) emitting materials were used in interiors adhesives, sealants, paints, carpets, agrifibers and woods. 42% of materials used in the construction of this facility were regionally extracted within BC. Sustainable Building Challenge- iiSBE Canada SB11 Call for Poster Presentations 3 Project Name: Kwantlen Polytechnic University Administration Building ‘C’ and Kwantlen Polytechnic Library Building ‘A’. Location: Surrey, BC Both Projects were started in 2005. Kwantlen Polytechnic University Administration Building ‘C’: Completion Phase 1, 2007, Phase 2, 2009 Kwantlen Polytechnic Library Building ‘A’: Completion 2009 Building Owner: (both projects) Ms. Karen Hearn Company Kwantlen Polytechnic University Address: Building C 12666 72nd Avenue 2nd Floor Surrey, BC V3W 2M8 Phone: 604-599-2448 Facsimile 604-599-2440 Size: Kwantlen Polytechnic University Administration Building ‘C’: 46,607 SF (4,330 M2) Kwantlen Polytechnic Library Building ‘A’: 56,000 SF (5,200 M2) Building Type/ use: Institutional Envelope construction: 60% Window/ Wall Typical Roof Construction: R20 HVAC Description and Daylighting systems: Natural Ventilation through tricklevents combined with chimneys provide 100% of ventilated air. All heating/ cooling is in-slab radiant coupled with geo-thermal. Facades are designed to be self shading on the south to allow side wall only lighting through slots on the west., and clerestory features were modelled through eight options to achieve atrium and library lighting with daylight and without solar gain or glare. For Kwantlen Polytechnic University Administration Building ‘C’: an Integrated Design Process was implemented to arrive at the following building system initiatives: a) Exterior Walls: Curtain wall glazing with operable windows and trickle vents on North, East and West façades. Rain screen walls with operable windows and trickle vents on the East, West and South façade. Sunshades on the South façade will allow winter sun in while shading the hot summer sun and protecting interior surfaces from glare. Consideration has been given to controlling the amount of glazing to on each façade to balance the factors of ample day lighting with potential heating and cooling loads. The Entrance Lobby off 72nd Avenue is fully glazed to maximize day lighting and provide an open dynamic entrance feature at the ceremonial front entrance to the campus. b) Structure: The basic structure of the building is concrete slabs, columns and shear walls. The Structural Shear walls at the exit stairs and stone feature wall as well as the shear diaphragms of the concrete slabs and steel cross bracing at the atrium roof are coordinated into the overall Architectural design and layout. c) Mechanical: Radiant slab heating and cooling is integrated within the structural slab. Trickle vents and operable windows for natural ventilation have been coordinated into the Architectural façade detailing. The locations of the operable windows and trickle vents allow for maximum flexibility of the potential design layouts. The atrium acts as a natural ventilation chimney to exhaust building air. The focus of the Integrated Design Process was to develop innovative sustainable building strategies, fully cognizant of occupant comfort, cost and maintenance implications, and Kwantlen’s current and future energy saving initiatives. LEED® Assessment achieved a Gold Certification. Actual or projected reduction in energy use from a reference building expressed as a percentage: 100% electrical hydro and purchased green power.
