ektós landing Niagatra Falls, CanadaSSEF Steel Competition

To reach out and touch the falls was the basis of the structural platform. The concept was derived from a species of snakes in Madagascar that elongate to reach branches or prey at a challenging distance. The skeleton of the snake inspired the system of trusses that support the platform. The snake is a type of ectotherm. (Ektós is from Latin (εκτός) which means “outside”, therm meaning “hot”, i.e. blood regulated by an external heat source)

The canopy is structurally supported using a combination of tapering steel circular HHS sections above, while being supported below by trusses. There are two types of trusses supporting the canopy, a simple “W” truss under the main body of the platform and a Space Frame truss under the “head”.

Consideration of structural stability was accounted for, leading to pylons that are anchored into the vertical cliff face.

hyperb(θ)lic CanopyToronto, Canada

Design a canopy for a luxury condominium building in Etobicoke. The requirements were for a dynamic and organic design. The submission that was approved was parabolic in nature.

Close to the site is the Humber Bay bridge which forms the identity for the area. Deconstructing the bridge to its basic forms lead to the idea of a sine wave. Further exploration lead to complex trigonometry formulas. The final result was the formula for Hyperbolic functions otherwise stated mathematically:

sinh(θ) = bcosh(θ) = ctanh(θ) = b/c

NUMBER DATE REMARKS

Condominium by-laws state sight lines are not to be obstructed, thus the structural beams shifted from above the glazing to being integrated within the canopy. The structural legs were originally compound curving HSS sections, however once consulting manufacturers’ the price was prohibitive. Basic trigonometry states; any three points forms a flat plane. The legs would be connected at three points and curved around that angled plane. Thus creating the illusion of compound curving structural HSS sections.

HydroFall TowersFoshan, China (2011)

The competition required a multifunctional building complex; two 50+ storey buildings for a luxury hotel, businesses and residential use with a base to serve as a shopping complex with various consumer based services.

The design intent was to establish a new identity for the Foshan district, creating sustainable practices primarily towards grey-water harvesting, re-use and to integrate the site with the rivers and streams.

Site analysis determined the state of water in the area to be riddled with pollutants due to the heavy industrial nature of the area and the care for existing water resources are non-existent. The building facades are designed to allow for infiltration of water which is collected and used for flushing toilets throughout the complex.

The concept design for the buildings were inspired by imagery of waterfalls.

Water collection on grade is accomplished via abstracted glass canopies that mimics petals of Orchids which are symbolic to the Chinese people.

The water that is collected is routed through a living machine to convert it to a potable water source. It will eventually reach an aquifer built on site, and then be reused.

The typology of the aesthetic was formed from combining the fluidity and dynamicism of the Chinese ribbon dance and the naturally occurring waterfalls. Fluid light streams of white represent the movement of the ribbon and the glazing represents the fluid that occupies the vacuum between the dancer and the instrument.

The requirements for the studio project was to place a Montessori school in the Roxton Parkette. The challenge was to manoeuvre the site due to the steep rise in slope from one corner to the other. To break up the site, inspiration was taken from peaks of mountains to abstract for the roofline of the building, affecting the programmatic elements within.

The form organically evolved from round elements to work with the elements on site. As the design progressed, stronger more edgier shapes form based on jagged peaks

The floor slabs for the ground floor plan shifts according to the average height of the ground so as not to threaten the shallow water table. Interested in allowing for the building to be handicap accessible, both entrances were able to be made to work with wheel chair access.

The sections show the gradual rising slope of the building in respect to the site. The building being elevated as it is, requires the tenants to rise up to the building, this is eased by the use of ramps on the outside. On the inside, the gym is elevated over the rest of the ground floor to accomodate for the site.

Research - Hearth HouseSmithville, Ontario (2012)

The goal of the project was to create an energy efficient rural home for the Aza family in south western Ontario. Importance was given to the rural location and addressing context. Environmental influences were paramount in achieving the goal. Involving the research of the following:

• Efficient Envelope Forms • Effects of Seasonal Winds and specific effects on ICF specific homes • Methods of diverting wind through change in landscaping elements • Determining the most efficient type of fireplace for a rural home • Innovative Distribution methods for heating the home effectively

Once the initial methodology was set, thorough research into each area was conducted by a fourth year Building Science class in Ryerson University lead by Dr. Ramani Ramakrishnan. Using varying degrees of software from basic CFD to more complex simulations via Wind Tunnel Testing and Autodesk Software, the students were able to build a comprehensive report on the house and the most efficient methodology.

Autodesk Inc. provided CFD simulation software to assist the students in their research, and a production team was involved in recording aspects of the project.

The clients were involved and witnessed the final results of the class.

*Currently under construction.

To achieve the least resistance, the form of the roof was created into a delta shape, low to the ground with a low slope and pointed towards the strongest wind direction. A raised berm across the direction of the current wind directs the wind above the roof.

Following examples of heat sinks used commonly in computers to expel heat away from the CPU, the concept is to bring the heat into the space through the steel stairs attached to the flue. While the chimney works as a thermal mass, the stairs act as a dispersion method of the heat being captured, allowing for more heat to radiate into the spaces around the fireplace.

Through conduction, heat is radiated from the fire source through to the flue, to the stair which is structurally supported by the CMU. The stairs are detailed in such a way that bare foot traffic will not be affected by the radiating metal stair structure. The structure is built to dispense heat through a radiative grill.

There are several design theories that have been implemented in the Hearth house that need to be reviewed, tested, detailed and possibly redesigned to review their efficiencies. The Ryerson University’s Architectural Sciences Department was to provide knowledgeable analysis on various components of the house. The group was to analyze the following aspects of the project:

The Deliverables:Resolve the questions listed above using scientific methods. Results must be presented in a graphical format that a lay person can understand.

The progress of the students research had to be reviewed throughout the semester. During this time, members from ATA were to provide insight regarding the expectations and requirements of the project. It also meant representing the clients and providing insight when it came to keeping aspects of the project within realistic budget limits.

Ryerson University - Winter 2012Guest Lecturer

• Aerodynamics - Does the shape of the house reduce the friction of the wind? - Is there a more efficient shape? How can the geometry be modified to perform better? - Could changing landscaping elements be useful? - How does the house perform in various seasonal conditions? • The Fireplace - How could the flue and chimney be designed and integrated? - How does the stairs connect to the stone chimney? - Is the stairs too hot to walk on? - How much thermal storage is available within the house • Southern Windows - What is the optimum angle for the windows? - What is the most efficient design details? - What is the most optimum glazing specifications for the windows? - Would louvers or Glazing Screens assist in better insulation?

Augmented Reality ExperimentMethods of Presenting Architectural Ideas

3D Studio Max EnvironmentProject Example: Spencer Smith Park Pavillion (ATA)

Interested in Augmented Reality and its possible applications in presenting ideas in a new way to clients. One of the tests was conducted on a project in the design phase. Created in 3D Studio Max using Flash complaint methods, the model was converted into Papervision 3D. A script was created in flash to understand when a Camera would detect a Tag and then display the 3d model in space relative to the tag. The proposal was to allow clients to hold a virtual model in his hands using a tag printed on paper or on smart phone.

or

=

1. The Tag is a marker for which initiates a program or a flash script to display information.

2. Tag can be used on a business card or a display on a phone.

3. Tag is read by the web cam, transferring the live feed to the program.

4. Computer equates the tag to represent a 3D model.

5. Computer places the 3D model over the tag “Augmenting Reality”. The user can rotate and move the Tag which moves the 3D model accordingly.
