TEAM: Joseph Jiang, Jonathan Hellinga, Shinyoung Seo, Samriddhi Shrestha

INSTRUCTORS: Joyce Kim, Elizabeth English

SOFTWARE: Revit, Rhino, AutoCAD, Lumion, Illustrator, InDesign, Photoshop, COMFEN

TIMELINE: 30 days

A climate responsive library project, located in Edmonton, Canada. This project aims to adapt to the harsh winter climate of Edmonton by leveraging thoroughly engineered building systems and site planning, while reducing the requirements of mechanical heating and cooling during the large temperature variances of the site location.

passive systems

By carefully planning the orientation of the building and the building systems, direct solar gains and passive ventilation can leveraged to heat and cool the building during the winter and summer seasons respectively. The south façade of the library is taller, allowing for an increased amount of sun during the winter seasons, while the overhang protects the interior from the high summer sun. West facing operable windows allow for a cross-breeze through the building, reducing the need for mechanical ventilation by 30% during the summer seasons.

sustainable design

Mass timber columns and beams, and CLT paneling allows the for large amounts of carbon to be embodied. Mass timber is also sustainably sourced from managed forests, which in turn reduces deforestation of habitats and natural environments.

thermal anlysis

The library design’s thermal experiential goal is maximum thermal comfort with minimal heating and cooling loads all year round. Visitors of the library should be comfortable in all areas of the library, such as the entry, reading areas, play areas, and washroom. Due to the very cold climate, the building will be expected to rely on mechanical heating. However, the design strives to significantly reduce this load through direct solar gain in the winter months. On the other hand, the inverse goal is to completely eliminate cooling loads in the summer, as Edmonton is not a very hot climate. Moreover, the design aims to have plenty of sunlight enter the building throughout the day to heat up the space, but not enough to overheat the space in the summer months. All in all, Edmonton’s climate makes mechanical heating unavoidable, however, through proper design and planning, this design aims to reduce mechanical heating and cooling loads significantly
