THE CENTRE FOR LEARNING WILL BE A LEARNING BUILDING. -Mission Statement form the Okanagan College Central Okanagan Region Website The Centre for Learning Building on the Okanagan College Campus exists, and was created to be, a location that can function not only as an innovative learning centre that strives for and supports a high level education for local, national and international students but also exists as a space that promotes the free exchange of ideas and the development and application of critical thinking skills. Not only is the Centre for learning a location where learning occurs, the building itself is an educational mechanism. Students and visitors can learn about the Centre s mechanical systems, how the building breathes and how the Learning Centre impacts other systems. Not only can this Centre educate its visitors about the principles of sustainability and the environment, the dialogue can also be detected between the Centre, the site and the social, historical and cultural roots of the location. The Centre s design reflects the natural surroundings of the valley as well as the historical origins of the region and, as a result, this centre in which learning occurs, can in turn educate its inhabitants. 3

COMPACT VERTICAL DESIGN REDUCES SITE COVERAGE 6
Theory & Design Principles As a 21st Century learning centre, this project combines urban, environmentally friendly architecture with a creative and accessible academic environment. With large expanses of glass, accented with metal and wood, the building character is contemporary while acknowledging the traditional with its wood beams, columns and local indigenous artifacts in the imagery. The existing library building was restored and incorporated respectfully into the massing of the building by the use of and Atrium and Agora. This allows the creation of an astonishingly successful social space for students, faculty and public. Service Quality Originally conceived as a sprawling horizontal addition to the campus, the design team proposed a much more compact vertical solution. By building up, rather than out, we reduced site coverage, eliminated the need for new parking areas, and created a landmark within the campus and the neighbourhood. The Centre for Learning is a five storey interdisciplinary facility that is constructed with a concrete frame and a steel framed roof, while the Atrium connecting it with the existing College library is supported by glulam wood columns and beams. The South façade of the atrium, also known as the Agora, stretches East / West along the pedestrian pathway and functions an indoor/outdoor circulation link that provides an iconic architectural expression for the Okanagan College Campus. The area of the Centre for Learning is approximately 6852 meters square with a building footprint of only 2078 meters square. The building was constructed per BCBC 2006. Occupancy classifications are A2 and D, with an occupant load of about 700 full time equivalents. Formal and informal spaces flow into each other so that their physical and visual connection between circulation areas, meeting spaces, classrooms, offices, the outdoors and the main atrium areas. It is an innovative building that functions well within the student focused vision that is exemplified by the College. 7

Centrally located, this walkable area is well served by transit, housing, commercial and recreational features. With its multi-use program, the Centre for Learning has become the heart of this compact, pedestrian oriented campus. The Centre for Learning building is sited adjacent to the main pedestrian cross axis, the south-facing entrance plaza, the open glass agora and the multi-storey atrium combine with the trees and planting to provide an active and interactive inner campus environment. Vehicle access is provided from the north side, where the internal campus street system gives access to the parking areas beyond. Bicycle parking is provided at the North entrance. The south facing atrium and agora entrances create a natural pedestrian flow for current and future campus layouts. The west garden provides private respite for the International student centre. Situated in a manner that encourages pedestrian and bicycle use and reduces traffic. The only parking provided is for shared hybrid vehicles and for vanpools. Shared hybrid vehicles are provided for use by the building occupants, and the only project parking provided is preferred parking for the hybrids and for vanpools.

The Atrium has created a popular informal meeting space which encourages academic and social interaction. The focal circular Centre for Dialogue room, prominently featured as a sculptural element hovering in the main atrium, is constructed of local wood and is designed to reflect the basket art of the indigenous people of the region, while the circular classroom it holds encourages the traditional learning circle concept of education. The intent of the design is to provide additional space for multi disciplinary programs at the college. The secondary aim is to create a flagship building for the campus. The grandeur of the facility will not only be fulfill the academic requirements of the College but also serve to facilitate the recruitment process needed to affirm the status of the Okanagan College as a destination for post secondary learning. The centre will not only respond to the growing need for high-tech learning, but will also emphasize the college s existing cultural and community links, providing a welcome, functional and dynamic place for learning, gathering and socializing. The site for the Centre for Learning is located immediately to the West of the existing Library building on a former parking lot that has been preloaded in anticipation of the design for a new facility. 8
LOCAL MATERIALS & CRAFTSMANSHIP "CENTRE FOR DIALOGUE" LEARNING CIRCLE Context & Site Between the Library and the preload, there is a strip of land currently occupied by existing mechanical plant. Therefore the construction of the Atrium structure, connecting the two buildings, required light weight structural solution. The same solution was applied to the area in front of the new building, the infill area beneath the third floor and in front of the Library building, which is the location of the Agora component. The design for the Centre for Learning follows a number of basic principles guided not only by the needs of the Okanagan College but by the contextual issues of the site. Throughout the Centre for Learning there is a focus on the movement through the building in terms of its programmed use related to types of gathering and learning. The intent is to create a variety of different spaces from more vibrant informal gathering through to quieter formal learning and office space. The inter-connected circulation leads users effectively through the building with minimum additional way finding required. The way that the building provides is having noisier informal gathering spaces on the ground floor and in the public atrium spaces; supporting informal, social interaction between disciplines, increasing ease of sharing facilities, and providing the potential for large-scale public events. The second floor has a more focused group gathering components that connected by bridges. As we move up the floors of the main building the uses become more specific in regard to classroom spaces and offices. This welcoming structure guides users through the building and its programming components in an intuitive manner. Connecting the two buildings with an atrium responds to a number of design objectives while also meeting the overall goal of creating a lively internal gathering space. The Agora meets the circulation requirements of the buildings by minimizing internal circulation needs within the five-storey massing as well as offering an exterior expression to the campus courtyard atmosphere. Exhibition of the activity of library announces its given function with Centre for Dialogue a powerful volumetric statement formalizing a sense of gathering and community. 9
NATURAL LIGHT Budget and Time Constraints Client satisfaction is high because the building was accomplished within its tight budget and time constraints, and is far exceeding their expectations for use, comfort and performance. In fact, occupant and user satisfaction is so high, that rooms are always fully booked. The Atrium and Agora are always busy with students and faculty alike; studying, sharing, and interacting; a true Centre for Learning. Sustainability Principles The programmatic layout, materials and construction techniques were created, selected and assembled to accentuate their environmental performance and durability. The use of materials was simplified and dramatically reduced with many raw construction level finishes exposed for added character. The Atrium is a showcase for many of the sustainable principles incorporated into the building. For example, the space is naturally ventilated though convection and requires no air conditioning even during the Okanagan summer heat. Mechanical louvers respond to heat load, and custom fritted glazing reduces summer heat gain. We have submitted this building to the CaGBC for LEED Platinum. The Okanagan College Centre for Learning contributes to the revitalization of the earth by adhering to our philosophy of renew, restore, and regenerate. The design of the building and the selection of materials respond to the need to support local products that enhance the local economy while minimizing environmental impact. Embodied energy from transportation to production have been evaluated and minimized. Materials have been selected for durability and adaptability, and most contain recycled content. During construction well over 90% of all waste products were recycled. A variety of techniques have been employed to safeguard and enhance the health and comfort of the occupants and builders. The building envelope incorporates advanced building technologies eliminating thermal bridging and avoiding moisture build-up. All interior adhesives, sealants, paints and coatings are low-emitting while all interior carpets, woods, and agrifibers are formaldehyde-free and low-emitting. Materials and ductwork were protected from contamination during construction, and filtration media were changed after construction. A green housekeeping program ensures that the high environmental quality is maintained during routine maintenance. 10
NEW LINKS TO LIBRARY LOCAL WOODWORKERS SHOWCASED THOUGH EXCEPTIONAL DETAILING Social and Economic Aspects The design of the building and the selection of materials respond to the need to support local products that enhance the local economy while minimizing environmental impact. Embodied energy from transportation to production have been evaluated and minimized. Materials have been selected for durability and adaptability, and most contain recycled content. During construction well over 90% of all waste products were recycled. Wood was used intentionally both as a structural and decorative element in the Centre for Learning. The intent is fourfold: to utilize a renewable resource while supporting only sustainable forestry practices, to support local products that enhance the local economy while minimizing environmental impact, to enhance occupant health, satisfaction and sense of well-being through the use of natural materials and to reflect the traditions of the region s indigenous people. Indoor Air Quality A variety of techniques have been employed to safeguard and enhance the health and comfort of the occupants and builders. The building envelope incorporates advanced building technologies eliminating thermal bridging and avoiding moisture build-up. The atrium is naturally ventilated through convection. Radiant slabs provide heating and cooling from highly efficient heat pumps using Treated Effluent Water from the City Treatment Plant. Also, heat from the office block is re-used in the atrium. 11

Gathering The building provides gathering spaces on the ground floor and in the public atrium spaces and as a result supports informal, social interaction between disciplines, while facilitating large-scale public events. The second floor has more focused semi-private group gathering components that are connected by bridges. Moving up the floors of the main building, the uses become more specific in regard to classroom spaces and offices. Dialogue The design for the Centre for Learning follows a number of basic principles guided not only by the needs of the Okanagan College but by the physical and contextual issues of the site. Due to existing soil conditions the construction of the Atrium structure required a light weight structural solution connecting the new tower to the existing library building. The solution to this site condition created an impetus for the construction of the Atrium and Agora. This welcoming structure guides users to and through the building, while also meeting the overall goal of creating a lively internal gathering space. The Agora meets the circulation requirements of the buildings by minimizing internal circulation needs within the five-storey massing as well as offering an exterior expression to the campus courtyard atmosphere. Exhibition of the activity of library announces its given function, while the inclusion of the Centre for Dialogue creates a powerful volumetric statement formalizing a sense of gathering and community. 15
CUSTOM CLADDING METALWORK Low Emissions: All interior adhesives, sealants, paints and coatings are low-emitting while all interior carpets, woods, and agrifibers are formaldehyde-free and low-emitting. Materials and ductwork were protected from contamination during construction, and filtration media were changed after construction. A green housekeeping program ensures that the high environmental quality is maintained during routine maintenance. Water Quality Water quality and aquifer recharge are enhanced with on-site rain water collection treatment and infiltration through vegetated bioswales. Potable water use is reduced through low flow fixtures and water efficient landscaping. 16
Potable Water Use: The plants and trees on this site have been designed to be irrigated by a high efficiency irrigation system. The landscaping consists of native and adaptive shrubs, trees and mixed planting (shrubs/ groundcover) as designed by Site360 Consulting Inc. (the project Landscape Architects). The shrubs on the plan are designed to be irrigated using a drip manifold system for high efficiency. This system applies water below the surface in an evenly distributed manner. This prevents wind drift, run-off as well as evaporation from the surface generally associated with a spray style of coverage as well as ensure that there is efficient and evenly distributed water coverage to minimize irrigation time and reduce excessive watering. In addition, the system has been designed to have 100% of its water provided by a source of Treated Effluent Water (TEW). The water originates from the City of Kelowna Waste Water Treatment Facility. A large outfall pipe takes the TEW to Lake Okanagan to allow the system to dissipate some of the heat that naturally occurs as part of the sewage treatment process. A staged pump was added to this system to pull water from the outfall in a 200mm diameter pipe and deliver it to the campus heating plant(maintenance Building). In the Maintenance Building the TEW is strained for "fibrous material" that is found in the solution (part of the natural sewage treatment plant operation). The TEW water is then treated with UV rays from the plant but is not treated to potable standards. A 50mm mainline pipe has been provided from the maintenance building to provide water for this site s landscape irrigation requirements. In summary, the use of this high efficiency irrigation system combined with a 100% nonpotable water source and a landscape plan which includes larger shrub areas with no turf area has reduced the water use by 100% from the baseline calculation. This project uses at least 20% less water than the baseline fixture performance requirements. 17
