2016 - National Winner: JASPER PLACE LIBRARY - Edmonton, AB
JURY COMMENTS: The bold sculptural form makes this library an enchanting focal point in an otherwise visually unremarkable suburban community. The transparent facade and overhanging roof are part of a passive design strategy, while at the same time blurring the distinction between the interior and exterior of the building. The clear span concrete roof facilitates future reconfiguration of the program, while its undulating form serves to articulate interior spaces of differing character. Overall an engaging project that makes a vital contribution to the quality of community life.
“What is a library that has no books?” This project presented an opportunity to explore this most contemporary of questions in physical terms.
The new 1,400m2 facility replaces an earlier branch library which formerly occupied the site, a prominent location in Meadowlark, one of Edmonton’s older suburbs. The client’s goal for the project was to create a new social focus for the community while providing a flexible building that would be responsive to the rapid changes currently taking place within the delivery of library services.
The building form is defined by a dramatic undulating concrete roof that rises from the ground plane in a gesture of shelter in the harsh north Albertan climate. The column-free structure creates a single large interior space that acts as the social heart of the building: its peaks and valleys creating differing characteristics and spatial conditions that help to define a variety of activity areas.
These areas - the ‘social spaces’ of the building - flow around and over the administrative components which form a rectangle in the southeast quadrant of the plan. The roof crests over the main double height reading room [which consists of book stacks and reading areas] descending on the east and west sides of the building, and opening up the north and south facades with large expanses of glazing. Roof overhangs and exterior louvres carefully control and articulate natural light.
The main public area extends above the staff zone to a mezzanine level overlooking the central reading room. The mezzanine houses additional collections, study rooms and public computers for community use.
Early evaluation of the buildings projected annual energy consumption anticipated a high demand for heating, due to the local climatic conditions, the pattern of building use and its open form. Strategies to conserve energy and reduce heating demand included a high-performance envelope designed to minimize heat loss and work effectively in combination with a displacement ventilation system.
Ventilation air enters the library through a raised floor that also serves to provide flexibility for spatial reconfiguration over time. Exhaust air is fed through return air grilles at ceiling level, utilizing the natural stack effect within the space to implement a heat recovery system which captures heat energy and re-uses it for pre-conditioning of incoming air, substantially reducing the heating energy demand. During shoulder seasons when conditions allow, natural ventilation is employed to reduce mechanical system use. The systems are controlled using a central Building Management System [BMS] which optimizes indoor conditions.
The high roof and the fully glazed south wall greatly increase the penetration of natural light into the interior of the building, substantially reducing the need for artificial lighting and associated energy consumption.
Materials specification focused on occupant health, durability and thermal comfort, with additional consideration given to regionally sourced and recycled products. Assemblies requiring regular maintenance or replacement during the life of the building were detailed to be easily accessible.
By achieving LEED Gold certification, the project has exceeded the client’s environmental performance goals, while fully meeting its other objectives. Jasper Place Library has become both an engaging architectural landmark and a popular meeting place for the surrounding community.
