in refugium
in refugium In Refugium was developed for entry in the opengap innatur_2 design competition for an interpretive centre. Participants chose their own location to explore the synergies between architecture and the natural environment.
TEAM: Jason Heinrich Will Krzymowski
LOCATION: Brooks Peninsula, Vancouver Island, BC
PROGRAM: The project focal point is the Refugium -- the lagoon structure that acts as a cryogenics laboratory, library, classroom, exhibition centre and tidal generator. A shoreline cabin and long house support full time researchers and visitors.
Above: At low tide, the lower section descends, generating energy from the gravitational force and exposing the collapsible spiral staircase and piles.
Left: Sketch of structure at high tide: the lower section rises meet the static upper section, generating energy from the buoyancy.
ROLES: I worked in tandem to create the concept, layout and form. Rendering was completed by Will Krzymowksi. Maps and sketch were created by Jason Heinrich. Diagrams and sections were jointly created.

district energy sharing system
Westhills is a new development of 250 single family dwellings and one 58 unit condominium and features a district energy sharing system that reduces energy consumption in the community by 35%. Started in 2008, the project is ongoing—120 more homes are scheduled for 2013.
The design approach begins with Demand Side Management, i.e. understanding and improving the energy efficiency of each building.
Secondly, the community energy loads are compared to assess the heating available from simultaneous cooling processes. Energy can be recovered using a unique district energy approach.
Thirdly, local energy sources are assessed for capacity and cost of energy. Once a community is connected via a district energy system, centralized renewable energy sources can be implemented.
Lastly, Future renewable energy systems are identified for addition to the existing network as the community grows.
CONSULTANT TEAM: DEC Engineering (Mech) Westhills Engineering (Civil)
LOCATION: Langford, BC
PROJECT: The district energy sharing system uses two pipe infrastructure to provide heating and cooling to heat pumps within the homes and condominium. Heat is recovered from buildings in cooling and the net imbalance is provided from a geoexchange field located under a soccer pitch.

The Vancouver Airport Authority has striven to reduce the environmental impact of Sea Island, most specifically greenhouse gas emissions. DEC Engineering was contracted to provide a conceptual design for a district energy system that uses local energy sources and is both environmentally and environmentally sustainable. The resulting concept can reduce emissions by over 82%. CONSULTANT TEAM: DEC Engineering

home of hope
home of hope The AIDS epidemic in East Africa and the Rwandan genocide have created a massive number of orphans and widows—the majority of which go without proper care. The Home of Hope is a vision for family style living with access to practical training, education, medical care, and spiritual well-being. Engineering Ministries International brought a team of volunteer engineers and architects to realize the dream with a master plan. LOCATION: Kigali, Rwanda
PROGRAM: Thoughtful development requires conscientious respect and understanding for local architecture and building construction. The first priority was learning local customs and methods. Afterwards, the master
plan was developed with the following elements: 29 clustered homes for one widow and six children to house a total of 168 orphans, 28 orphans, and one caretaker; church; school for 400 children and evening classes; and medical clinic.
ROLE: As an intern with Engineering Ministries International, I assisted with the surveying, layout, modeling, and design of the potable water and wastewater systems.
Right: A man and his child at a neighbouring house to the property. The home has a concrete foundation and is primarily made from locally fired clay bricks.

Above: Children play at a local school in a nearby district of Rwanda. Outside of city centres, facilities are often minimal but provide an opportunity for local children to be educated.
Below: A bird’s eye view of the south end of the property. The church also functions as a gym for the school. Buildings are oriented to maximize natural sunlight and natural ventilation from the predominant northerly winds up the hillside.
Above: The site plan for the development. Public spaces such as the church, school and medical clinic are located at the south. The property terraces upward, where the homes for widows and orphans are located. Land between homes can provide agriculture and play areas. Unfortunately, the government annexed the land the following year to make room for a power generation plant and transmission lines. The Home of Hope organization is currently seeking new land.

fuel cell water management
Polymer Electrolyte Membrane fuel cells will become flooded with water byproduct that is not evacuated from the cathode micro-channels. Water management is a prime concern of research, but the surface wettability effects of the micro-channel has yet to be investigated.

in current fuel cells to provide more efficient water removal, thus increasing the efficiency and reliability of the fuel cell.
The hydrophilic glass slides and graphite plates showed a preference for water flow in between the slide and GDL interface. Hydrophilic glass slides showed a preference for water to remain outside of the interface. The latter result could be utilized
ROLE: I performed all experimentation and photography of the droplet interaction and developed all figures for the publication.

spinal disc
pressure sensor
Pressure sensors are used for measuring spinal disc pressure to identify disc injury and degeneration. Current needle mounted strain gauge pressure sensors are over 1mm in diameter and injure tissue Optic fibre based sensors have the potential to be less than 0.4mm in diameter and are flexible, causing less tissue damage.

Jason Heinrich Dr. Peter Wild Inset: Section view of sensor
PROJECT: Fibre optic pressure sensors use Fibre-Bragg gratings to measure pressure—etched portions of the optic fibre reflect a specific wavelength of light, which shifts as the fibre is stressed. Existing sensors have been fabricated and tested; however, the sensors are sensitive to temperature as well as pressure, which causes false readings.

to temperature. One prototype was 0.21mm in diameter, making it the smallest needle-type pressure sensor in the world. Preliminary results were successful, but future testing is required before the sensor can be considered for clinical trials.
Several concepts were developed. The final concept used two Fibre-Bragg gratings, one of which was fixed in place such that it was only sensitive
ROLE: I worked independently to design, fabricate and test the sensors, under the supervision of Dr. Wild. 2X SCALE

blended body
aircraft
A blended body passenger aircraft was developed for the 2008-2009 AIAA Undergraduate Team Aircraft Design Competition, which required a 150 passenger aircraft with a maximum range of 2,800 nm. TEAM:
Jason Heinrich Andrew Freire
PROJECT: Blended body aircraft use an airfoil for the body, which increases efficiency and reduced drag compared to the cylindrical fuselage of a conventional aircraft. The airfoil, body and wing size/shape, and horizontal and vertical stabilizers were designed to balance numerous considerations:
• • • • • • • • •
seating, headroom, emergency exits, luggage and fuel storage, stall speed, take-off weight, climb gradient and angle, cruise speed, max ceiling,
• • • •
turn rates, landing distance, stability, and structural integrity.
The final concept weighed 20% less and consumed 16% less fuel than Boeing and Airbus competitors. ROLE: I was responsible for the layout and spacial design of the aircraft, airfoil selection, and renderings. The specific flight characteristic calculations were performed by Andrew Freire.

wind turbine
dynamometer
In partnership with Aria Wind Power Inc., the University of Victoria tests scaled models of wind turbines in water tunnels. However, few wind turbine dynamometers (devices that measure forces on a turbine) are commercially available and those that are do not allow for yawed operation or testing of both horizontal and vertical oriented turbines. TEAM:
Jason Heinrich Logan Volkers Corry Martin Gurman Gohalwar
PROJECT: A dynamometer was developed for a 4’ x 5’ x 16’ water tunnel that could measure multiple forces on a horizontal axis and vertical axis turbine. The final design included a submerged pod that housed a mounting shaft and sensors to measure radial and thrust forces as well as a lid mounted motor and belt drive system with a torque sensor.
ROLE: I developed the submerged pod including seals, shafts, bearings, sensors, and housing.
Left: Horizontal turbine on dynamometer. Motor and belt drive are mounted on the water tunnel lid, while turbine and pod are submerged.
Below: Section view of submerged pod showing cut away of the housing (gray), bearings (pink), dynamic seal (purple), and sensors (green).
