COLONEL DICKSON COMMUNITY CENTER TINY LIBRARY PROJECT – PHOENIX, AZ Course: AE 300 Architectural Engineering Studio 1

Team: Aman Chand, Amrit Mangat, Liam Joseph Bray Software: Revit 2025

Date: June 2024 – August 2024

Course: AE 225 Environmental Design Studio Team: Amrit Mangat, Olivia Francom, Cristian Basile Software: Revit 2024, AutoCAD 2023 Date: October 2023– December 2023 The Tiny Library is a project that encourages the consideration of climate variables in making design decisions.

Phoenix’s hot, arid climate can provide great benefit in applying passive design strategies to enhance the occupant experience within the library. By analyzing the sun path during the summer and winter months and the wind behaviour in Phoenix, we decided to prioritize sun-shading, natural daylighting and natural ventilation in our library design.

The Colonel Dickson Community Center (CDCC) is a new community hub located in Cambridge, Ontario. Housing a library, gymnasium, and various communal and corporate spaces, the building is welcoming to all members of the community.

The overall design aims to captivate the local neighbourhood and invite pedestrians to experience all that CDCC has to offer. With a vegetative balcony and cantilevered library façade, CDCC uses complex enclosure methods to ensure all occupants are surrounded by the unique design choices that define the architectural intent of the building. The building is clad with a mix of wood slats, aluminum composite panels, and stone composite panels, with plenty of glass to let occupants connect with the outdoors.

VEGETATIVE BALCONY

The vegetative balcony is located adjacent to the viewing track surrounding the gymnasium. The balcony is cantilever from the primary structure with a tension cable that connects it to the roof structure, resembling a simply-supported system. The balcony itself is split into two parts: the maintenance walkway and the vegetation itself. The walkway is finished with pavers on pedestals, allowing workers to safely access the vegetation. These two parts of the balcony are lined with modified-bituminous waterproofing and features an aluminum composite (ACM) panel fascia with a wooden panel soffit

LIBRARY BOXOUT FACADE

The library boxout façade is one of the most prominent features in the building enclosure, giving the community center its welcoming character. The white outline of the boxout projects over the sidewalk and identifies the extents of the library located at the east wing of the building.

The boxout is clad with aluminum composite panels (ACM) and transitions to a wooden panel soffit. Due to project time constraints, we were unable to include the vertical fins in the detail within the expected timeline to focus on other higher priority deliverables.

02 TINY LIBRARY PROJECT – PHOENIX, AZ Course: AE 225 Environmental Design Studio Team: Amrit Mangat, Olivia Francom, Cristian Basile Software: Revit 2024, AutoCAD 2023 Date: October 2023– December 2023 The Tiny Library is a project that encourages the consideration of climate variables in making design decisions.

Phoenix’s hot, arid climate can provide great benefit in applying passive design strategies to enhance the occupant experience within the library. By analyzing the sun path during the summer and winter months and the wind behaviour in Phoenix, we decided to prioritize sun-shading, natural daylighting and natural ventilation in our library design.

CLIMATE STUDY AND MODEL Prior to drafting the preliminary design, we examined a sun path and wind analysis using Climate Consultant and CBE Clima Tool. These resources provided the information to base our design decisions.

The project initially required us to create a 3D model of the library using foamcore and other materials. This 3D model must have an overall window-to-wall ratio (WWR) of 30%.

The model was further studied on a temporary heliodon with the equipment available.

To best leverage the abundant sunlight in Phoenix, we used vertical fins on the east and west elevations to welcome the early morning sunlight while blocking out the excessive solar heat gains in the mid to late afternoon. The extended roof overhang further aids the prevention of solar penetration in the early afternoon.

FLOOR PLAN The 18 m x 10 m tiny library design is governed by a central seating area in the shape of a segmented infinity loop. The infinity loop design is projected up into the central light fixture. Beyond the light fixture is a dual-purpose, mechanicallyautomated recessed roofing system that promotes natural daylighting during the day and night-flushing during the night by opening the glazing units to let warm air exit the building. The interior is primarily finished with wood to foster productivity and wellness.

The library includes 40 m of linear bookshelves in varying lengths to meet the project requirements. An exterior seating area is located in the corridor between the exterior wall and shading device on the east elevation.

ELEVATIONS AND SECTIONS

ELEVATIONS AND SECTIONS

The library design uses a combination of copper, fiber cement, and terracotta cladding around the building. The materials were selected based on architectural vision and thermal performance considering the extreme heat in Arizona. Behind the cladding systems is a concrete masonry backup wall to leverage the benefits of thermal mass to passively cool to interior space.

ELEVATIONS AND SECTIONS

The renders shown above and below encompass the cladding selections on the west and east façades, respectively. Both elevations use angled vertical fins to mitigate solar heat gain and glare at different times of the day. The render below highlights the vertical fin corridor shading at 7 am (on the right) and 10 am (on the left). By noon, the roof overhang becomes the primary source of shading.

ENVIRONMENT 1 RECLAD PROJECT

ENVIRONMENT 1 RECLAD PROJECT

Course: AE 200 Enclosure Design Studio

Team: Aman Chand, Tania Hagopian, Olivia Joyce Lum Software: AutoCAD 2022, Rhino 3D, Revit 2023, Lumion Date: February 2023 – April 2023

Environment 1 (EV1) is the oldest building in the environment faculty at the University of Waterloo. Standing over 50 years, it is home to 2500 students and staff members and features classrooms, office spaces and study rooms.

With evidence of a decaying solid masonry façade, occupants are often uncomfortable due to the poor thermal performance of the enclosure system and opt to work on other parts of campus.

This project aims to revamp the central building of the environment with a striking new façade that improves on performance and aesthetics.

3 Main Design Objectives: • Energy performance and air tightness • Low maintenance materials • Occupant comfort Please note that the scope of work is limited to the southeast wall, highlighted in red on the right

To kick off the EV1 Reclad Project, we conducted some research using IR imaging to expose the underperforming façade. Images were taken on a day where the exterior temperature was around 0°C. The top two images highlight how the interior temperature seeps to the exterior wall and the bottom shows the reverse operation. The lack of air tightness is a large factor in the occupant discomfort in EV1.

EV1’s brand new enclosure system features an aluminum-composite panel exterior, alternating between grey and green strips. The most distinct feature in the upgrade is the shading device, specifically designed to give the façade function and character. With a vision to incorporate biomimetic design, the cavity in the shading device form a leaf shape, ultimately emphasizing the presence of an environment building.

Situated on the southeast side of the building, the façade will receive an abundance of sunlight throughout the year. The shading device aims to combat the morning sun from the east and the peak sun from the south, allowing occupants to rest assured glare will not impact their workflow.

The southeast part of EV1 is home to office spaces for staff members; one common complaint we received from occupants on all three floors was the lack of natural light entering their offices during the day. The new design has increased the window-to-wall ratio (WWR) from 15% to 26%.

This project aligns with the University of Waterloo’s climate action plan Shift:Neutral to achieve carbon neutrality by 2050. The design aims to limit the amount of greenhouse gas emissions by creating an enclosure system that prevents the overcompensation of operational procedures.

MODIFIED WALL SECTION

PREFABRICATED CONSTRUCTION With the University of Waterloo offering co-op for most of their programs, it is pivotal to finish the retrofit in a short period of time. To accelerate the construction process, the design features prefabricated construction for the second and third floor enclosure system.

The prefab panel consists of the ACM panels and windows within a bay of the façade, It also features the hollow structural steel supports for the shading device, allowing for relatively quick installation on site.

TH

SHADING DEVICE Using hydroforming technology, the shading device is tailored to shade against the sun path hitting the southeast wall of EV1. It allows natural light to enter the office spaces while minimizing glare, ultimately improving workflow and sense of wellness.

WATERLOO PARK PAVILION PROJECT Course: AE 125 Structural Design Studio Team: James Wong, Gabriel Codina, Olivia Joyce Lum Software: AutoCAD 2021, Rhino 3D, Enscape Date: June 2022 – August 2022

The Waterloo Park Pavilion Project targets improving the cultural identity of the Kitchener-Waterloo region. With a rising tech-hub, cultural festivals and two neighbouring universities, the City of Waterloo lacks a central symbol that encompasses its identity.

The mass timber structure brings a new, central landmark for students, pedestrians and artists to gather and celebrate together. The new pavilion features: • A seating area to relax from the sun, play board games and share a meal

• A performance stage open to the public for children and singers to share their talent • Display cases for the City of Waterloo to showcase local artwork

STRUCTURAL DESIGN

The pavilion features a glulam structure that is anchored down with a steel plate into the concrete footing to prevent lateral movement and provide a fixed moment connection. The floor layout features a circular ring for the beams to attach to and support the joists running above. The glulam beams sit in a galvanized steel column base to connect to the footing to act as a structural system for the floor joists. The combination of 2 structural systems was to ensure both dead and live loads were sufficiently supported for occupant flow and harsh weather climates.
