0.1 NET ZERO HOME HANNOVER, ONTARIO This project is a design of a net zero energy consumption home in a rural area near Hanover, ON, Canada. A family of four is intended to live in the 1500-2000 ft2 home. It has 3 bedrooms and 2 bathrooms and is two storeys tall. Through the use of building science knowledge, calculations and simulation softwares such as Ecotect, RETscreen, and HOT2000, the spacial and system design for the house were collaborately decided by a team of three.

Basement floor that accomodates the bedrooms and has direct entry to the greenhouse. The greenhouse has two walls that are designed to be movable to allow for East to West breeze during the summer
LIVING ROOM RENDER Sketch render shows the use of rammed earth walls, slope of the roof in the living room space, resin coated concrete thermal mass flooring. Windows are mainly placed on the south elevtion to face the greenhouse. There is only one narrow window that is in direct contact with the exterior to prevent excessive heat loss
DETAIL SECTION 1:100 The section exhibits the placement of the greenhouse, use of strawbale for the north wall, rammed-insulated earth wall for the interior wall, exterior glazing for an effective south facing greenhouse, thermally efficient concrete flooring.

0.2 DOWNSVIEW SPORTS FACILITY EVOLVE NET ZERO DESIGN COMPETITION: THIRD PLACE The project required the team to design a Net zero sports facility in Downsview Park, Toronto. The entry won 3rd place for its design and energy performance. The proposed facility for the rehabilitation centre carefully considers the programmatic elements to dictate a form that emphasizes passive ventilation strategies, views, day lighting and water efficiency. Through the exploration of surrounding neighbourhoods, it is made notable that the proposal for design has the ability to hold a variety of characteristics that are sustainable.

0.2 DOWNSVIEW SPORTS FACILITY EVOLVE NET ZERO DESIGN COMPETITION: THIRD PLACE
Through the integration of multiple sustainable techniques, the overall life cycle costs of the building have been significantly reduced in the proposed design. A thorough analysis of the implemented water, energy and heating systems has been conducted to form a net zero building. The system that will be incorporated on the roof of the sports performance facility is a PV and thermal hybrid system (PVT). The PVT addresses the majority of a building’s energy requirements. It accounts for both heat and electricity and allows for the production of two types of energy within single equipment. PV modules produce electricity while the excess heat from PVs is used to pre-heat fresh air entering the HVAC unit. Water efficiency is also extremely important in an environmentally responsible design. Two types of systems were carefully chosen to compliment the water use of the building. Low flow fixtures and rainwater harvesting will be implemented into the building design. Rainwater harvesting is the main source of water conservation within the building. The roof starts quite tall on one elevation of the building before sloping down towards the other side. This slope allows rain water to be collected at the lower end, concentrating and maximizing the collection of rainwater. DESIGN DEVELOPMENT

0.3 233 RHODES AVE, TORONTO HOUSE IT DESIGN COMPETITION: SECOND PLACE HouseIt is a leading company that allows student participation through a competition based platform to provide clients with more than one quality based design. The project was based on a house within downtown Toronto where the client was looking to “modernize� the Victorian brick home. My aim was to provide the necessary retrofit design along with reducing the energy consumption of the design through the use of high performance glazing and highly insulated walls.

0.3 233 RHODES AVE, TORONTO HOUSE IT DESIGN COMPETITION: 2ND PLACE
EXISTING TOWNHOUSE
L
ocated within downtown Toronto, 233 Rhodes Ave. is a townhome constructed predominantly using brick masonry. The house currently sits on a narrow plot of 7.1m by 39.7 m and occupies 74 sqm of built area. The client requested the gross area to be increased by approximately 200 sqm of gross area by extending the main floor, basement and the second floor. For renovation purposes, all the existing walls of the house have been retained and the location of the stairs through the three levels of the house. The exterior cladding is proposed as fiber cement panels as they are cost effective and provide an elegant modern finish to the design. The balcony and extruded portions have been finished with wood slats to ensure light filters through the windows and yet increases privacy. As for the floors, the basement design proposes underpinning to increase the floor to floor height and the second floor level is higher to allow for more sunlight to enter into the central portions of the house during winter. Overall, the finish of the floors is proposed as wooden decking to compliment the interior brick walls. The aesthetic design quality was chosen as a modern contemporary exterior complimenting a modern rustic interior. EXTERIOR RENDER SOWING CHANGE IN MATERIAL AND ADDED BALCONY AND DECK

Since the existing structure had to be retained, the design proposed added insulation on the interior.
Roof top
HOT2000 simulations were conducted to estimate the reduction in energy consumption by adding different amounts of insulation. It was understood that after meeting the SB-10 guidelines for R-30 walls, increasing the insulaiton did not affect the overall heat loss as much. Thus, the wall is designed to meet SB-10 guidelines only.

The roof was altered to a flat roof based on the clients requests.
