DAS HAUS
THE CORNER HOUSE
Project Summary
DAS HAUS’ Corner House project is located in Toronto, Ontario, Canada. The building is a three storey residential structure with three units. The ground floor unit is designed to accommodate various potential occupancies: residential, retail, café, or office, with the majority of our analysis focused on a café occupancy. The other two units each occupy a half of the second and third storeys. The goal of this strategy is to provide energy efficient housing in a higher density mixed-use context.
Relevance of Project to the Goals of the Competition
The goal of reaching net-zero energy is made significantly more difficult by prioritizing mixed-use and higher density living. However, we strongly believe that addressing this urban housing condition is critical for developing sustainable communities at a larger scale, especially in Toronto where additional affordable residential housing is desperately needed in walkable mixed-use communities. Our project represents an archetypal solution for innovative residential development that also meets energy performance targets.
Design Strategy and Key Points
The project includes several important strategies for maximizing the performance of the building. These include: a high performance building envelope, a maximized south-facing sloped roof for energy generation, majority southfacing glazing for winter solar heat gain and improved daylighting quality, a centralized service core for efficient distribution and maximum occupiable space, enhanced natural ventilation, and an integrated mechanical system shared between all units.

B. DESIGN GOALS + PROJECT CONTEXT 2.1 PROJECT INTRODUCTION
As environmental issues have become more mainstream, the concept of “sustainability� has lost some of its original meaning. The word itself has become a staple of contemporary marketing campaigns, occasionally with unscrupulous intentions. In light of this it is important for designers to articulate a clear vision for sustainability projects, keeping in mind clear goals and scopes.
a larger scale. As people continually move into city centers such as downtown Toronto, there is a growing need for high-density living in multi-use neighbourhoods. The suburban model of large single- family homes situated on generous lots has proven to be no longer a practical, economical or ecological way of living. City living demands for smaller living units in mixed-use neighbourhoods where live-work opportunities exist.
The Corner House was designed and conceived to address the obvious issues of energy and resources efficiency (e.g. consumption, renewable energy, thermal performance and passive strategies). However the project also engages with sustainability issues affecting urban settings at
The Corner House takes advantage of the commonly underutilized corner lot to showcase a new typology of sustainable living. The main concept centers on providing a flexible ground floor with residential living pushed above. The integration of mixed-use programming and high
performance construction creates a new approach to urban buildings that is both culturally and environmentally sustainable.

2.2 PROJECT LOCATION Toronto Toronto, like many urban cities in North America, was developed with a gridiron system consisting of major and minor roads that run perpendicular to each other. On a typical urban block, major roads are occupied with commercial frontages while minor streets contain primarily residential housing. Although this is an effective organization of space, the intersections between these major and minor streets become problematic and under designed lacking a cohesive solution that includes both frontages. In many cases, this results in blank facades that fail to acknowledge unique site conditions of corner lots. Chosen as a demonstration lot for a typical corner condition in Toronto, the project is located just 5 minutes by car from downtown Toronto. The site, at Dundas Street East and Boulton Avenue, is situated on the southern border of the well-established Riverdale neighbourhood, home to a vibrant family culture. The lot measuring 69 ft wide by 46 ft deep, the 3,174 ft2 is oriented in the east-west allowing where it allows for maximum solar exposure and optimal passive ventilation. Given its urban context, the site is within walking distance of three schools, public transit, and multiple parks. Also, the dedicated bike lane on Dundas Street allows for a short and safe bike ride to and from Cherry Beach recreational area.

2.3 NEW TYPOLOGY
Designed as a flexible building typology adaptable to different urban sites, the Corner House proposes a new building typology for underutilized corner lots within the city. It provides commercial and residential programming that takes advantage of two street frontages. The flexibility of the design is achieved through the highly efficient and densely programmed service core that houses all plumbing, electrical, and mechanical work. Measuring 8ft in width, the core includes street entry, vertical circulation, main washrooms, kitchen areas, and a stacked mechanical, electrical, and plumbing chase wall. Fixing the service core, with all the essential services, allows for the living and bedroom spaces to expand and contract based on changing site constraints of other lots. This also allows for an open concept to the third floor living area and varying bedroom options.

2.4 ARCHITECTURE + PERFORMANCE GOALS Context
Low impact materials
Toronto is one of Canada’s southernmost cities, nevertheless its climate is still relatively harsh, with very cold winters. In fact it suffers the additional problem of very hot humid summers. This climate, especially the humidity and precipitation patterns, is a result of Toronto’s proximity to the Great Lakes. Prevailing winds tend to come off the lake in the summer, and from the north in the winter. These conditions will be addressed through the design of the building.
Materials that are recycled, local, or have low embodied energy were prioritized in the design. This includes dense pack cellulose for insulation, wood framing, wood fiberboard sheathing (SONOclimate ECO4) [8], beetle kill ash siding, exterior clay plaster, and wood flooring.
The sustainability strategy will incorporate low impact materials, renewable energy generation, high performance envelope, flexible energy efficient mechanical system, passive solar design, maximized daylighting, and passive ventilation. Our overall energy efficiency goal is to generate 50% of the energy consumption of the building. The building was also designed to meet LEED Platinum under the LEED for homes certification. To achieve LEED Platinum a total point score of 90 is generally required, however, due to the high density of this project a home size adjustment of -8 is added. Our building exceeds the LEED platinum requirement, achieving a total of 96.5 points. See Appendix B for the complete LEED checklist.

In Ontario, the microFIT program provides financial incentive for homeowners to implement “micro” renewable energy projects (<10kW) on their site. The program provides a guaranteed price for the electricity ($ 0.39/kWh) sold to the grid for a 20-year period. Renewable energy technologies may include solar photovoltaic (PV), wind, waterpower or bioenergy. To take advantage of this generous program 1000 ft2 of south facing roof is designed to incorporate a 8.8 kW array.
High Performance Envelope High R-values are attained through a double stud wall system that eliminates thermal bridging. The stud cavity is insulated with dense pack cellulose. In the roof blown cellulose in the So la r Po w er G en er at io n

Mechanical system The heating, cooling and domestic hot water systems are integrated into a single building-wide Variable Refrigerant Flow system. One exterior condensor and eight interior evaporators provide flexible zone conditioning.VRFs allow for heat to be redistributed through out the house, this is able to take advantage of periods when the building requires both heating and cooling to provide substantial energy savings. A dedicated outdoor air system will provide ventilation. Supply air will be brought into the house through a heat recovery ventilator (HRV) to reduce energy demands by recovering heat from the exhaust air.
Passive solar and daylighting One consequence of Toronto’s northern latitude is pronounced differences between the angle of the sun in winter and summer. Low angle winter sun is easily allowed into the building, while high angle summer sun is easily blocked with appropriate shading devices.Winter heat gain is facilitated by an east-west orientation with a larger number of windows on the south. Lighting analysis was conducted to size and place windows to maximize daylighting.

joist space is supplement by continuous exterior extruded polystyrene insulation. Low U-values for the fenestration are achieved with triple-pane argon-filled low-e coated Insulated Glazing Units, installed in conjunction with fiberglass frames. High performance wall assemblies have increased susceptible to moisture damage. Hygrothermal analysis was performed to ensure the assemblies are not vulnerable to this issue.
Passive ventilation Operable windows will allow for natural ventilation during mild periods. Placement of operable windows on the north and south side of the third floor take advantage of prevailing winds to provide cross ventilation. An open staircase linking the three floors allows air circulation to occur through the entire building.

2.6 FLOOR PLANS Residential - Rental Unit The third design is a residential unit. Imagined as a rental unit, or an in-law suite, the floor plan is simple and straight forward. With the essential services located in the same place, other occupancies can be created through the more open living spaces and bedrooms. This design allows for a fully handicap accessible residential unit which provides the potential for grandparents or elderly tenants to live below their family. The most private space, the bedroom, exits onto the patio allowing for a personal connection to the exterior.

2.6 FLOOR PLANS Second Floor - Bedrooms The second floor of the Corner House is the most private in both units. Proposing two different unit layouts, the typical condition contains two bedrooms and a den, each of which has their own operable window. Included on this floor are two bathrooms per unit, one located within the dense service core, and one acting as an ensuite. Both bathrooms back onto the main service wall of the building. The bedrooms were moved to the second floor in order to allow the living space to be elevated to the third floor.

Third Floor - Living Space As the most unique and dynamic floor, the third floor was designed to take advantage of the views, balcony space, and the cathedral ceiling by flipping the traditional orientation of the bedrooms to below the living space. The open concept allows for different furniture layouts including the potential for an office space, children’s play area, or typical family room configuration. The large south-facing glazing allows for maximum solar heat gain during the winter while exterior shading blocks solar heat gain during the summer. This reversal also allows both units to enjoy a generous balcony space designed to facilitate the drying of clothes during the warmer months.

2.8 INTEGRATED DESIGN APPROACH
The DAS Haus team is comprised of Masters of Architecture, and Masters of Building Science students. Decisions balancing the architectural and performance goals of the project were made through discussion between team members. Faculty advisors and external support provided guidance on important issues such as local materials, constructibility, mechanical systems design, and envelope durability. At Ryerson the studio culture traditionally experienced at architecture schools is shared between the architecture and building science programs presenting a new type of work environment that encourages collaboration.

C. ENVELOPE DURABILITY ANALYSIS 3.1 ENVELOPE DESIGN APPROACH
The building envelope was designed primarily to protect against the potentially damaging effects of heat, moisture and air transport through the assembly. During the design of the envelope the following considerations were taken into account: 1. Bulk Water Management – The most important consideration in assuring envelope durability is the management of bulk water. In light of this consideration, a galvanized standing seam metal roof and ventilated rain screen wall system were selected to act as the first layers of defense. In addition to this housewrap provides a drainage plane in the wall, and a 2-ply asphalt impregnated building paper provides a drainage plane in the roof. Large eaves, and metal flashings direct water away from contact with the exterior wall. 2. Air Control – Often overlooked in typical residential construction, the air barrier system is critical to the design of our envelope system. Taped plywood joints on the exterior sheathing of the exterior wall and roof provide air tightness. Special attention was taken specifically at the roof-wall connection and the envelope penetrations to ensure the continuity of the system.

Polyethylene Sheet (Vapour Retarder) 1/2” Gypsum Wall Board Zero VOC Paint (EPA AirPLUS)
3. Thermal Control – As a result of the cold climate and significant temperature changes throughout the year, it was critical for our design to include a well-insulated wall and roofing system with minimal thermal bridging. To this end we choose a double-stud cavity wall system and external continuous insulation in the roof. 4. Vapor Control – The control of vapor movement moisture flow in the wall is vital within a humid climate like Toronto. In the wall a typical vapour retarder layer on the interior side of the thermal control layer was designed to allow for moisture to dry outward. In the roof assembly an exterior vapour retarder allows the roof to dry inward. 5. Cost & Constructibility – With the goal of providing affordable high performance housing a double stud system with a 13” cavity (6” clearspace) filled with dense-pack cellulose insulation was specified. This not only reduces time during the construction process, by eliminating the need for exterior insulation but also by reducing high cost materials like XPS. 6. Natural Materials – As a team we decided that it was important to reduce the amount of plastic and asphalt based materials in the Corner House. This was an important consideration when choosing insulation types as high performance envelope assemblies typically use large quantities of insulation. In addition to cellulose insulation in the roof and wall assemblies, a reclaimed beetle kill ash siding was used. All lumber in the envelope (with the exception of local products) will be FSC certified.

3.2 ENVELOPE DETAILING AND HYGROTHERMAL ANALYSIS Hygrothermal and Thermal Bridging Modeling WUFI, a transient two-dimensional heat and moisture transport modeling software, was used to perform hygrothermal analysis [1]. The models tested the building components over a period of three years. Wall and roof assemblies were investigated to determine the drying potential of these envelope elements. The simulations assume that the initial moisture level are 80%. In addition to the testing of the whole assembly, the water content of specific material layers was investigated, especially those organic materials prone to mold growth and rot. Typically materials were considered safe if the moisture content remained below 20%. THERM, a two-dimensional conduction heat-transfer modeling software, was used to calculate thermal bridging potential within the envelope [2]. Thermal bridging within the envelope can increase the risk of condensation and water damage to critical materials. The Canadian Passive House Institute considers an envelope with psi value of <0.26 Btu/hr·ft·F° to be thermal bridge free [3].
Exterior Walls Bulk Water Management: Wood siding provides a rain screen, deflecting the majority of the bulk water that comes in contact with the exterior wall. Water that passes this control layer is then drained out of the assembly through a 1” air cavity and drainage plane. Sloped aluminum flashing at the head and sill of windows, at important material joints, and at the base of the building help to repel wind driven rain. Air Control: The primary air transport control layer is an exterior plywood sheathing with fully taped seams. This sheathing layer continues up the wall and connects to the roof with a tapped and lapped membrane to ensure the continuity of the air barrier is continuous. Expanded foam gaskets and silicone
sealant joints are used at window, door and vent penetrations to complete the air barrier system. Thermal Control: The exterior wall is insulated with dense-pack cellulose. The double stud wall system minimizes the thermal bridging through the framing elements by completely separating an exterior (structural) wall from an interior wall with a 13” cavity (6” clearspace). This strategy reduces the heating and cooling loads and provides improved occupant comfort by eliminating cold spots on the surface of interior walls. Because the exterior wall is structural some thermal bridging will still occur through the floor joist. This bridging is significantly reduced by using engineered wood floor joists, and by insulating against the rim joist with dense-pack cellulose capped by spray foam. The Y (psi) values at critical points of the assembly are between -0.01 and -0.03 Btu/hr·ft·F°. Vapour Control: A polyethylene sheet located beneath the gypsum board acts as a vapour retarder, reducing vapour diffusion into the insulation cavity from the interior. The small amount of moisture that passes the vapour retarder layer is allowed to dry outward. Air circulation within the vented cavity improves the drying capacity of the overall system.
Figure 3.2.1 Water Content of Plywood in the Wall Assembly
Figure 3.2.2 Water Content of Cellulose Insulation in the Wall Assembly
WUFI: Simulation results show the total water content of the wall assembly decreases over the three year period of investigation. This indicates that the wall has adequate drying potential and that water content will not accumulate within critical components in the walls. Figure 3.2.3 Total Water Content of the Wall Assembly
Envelope Durability Analysis

Sloped Roof Bulk Water Management: The galvanized standing seam metal roof will deflect the majority of the bulk water away from the roof assembly. Any wind driven rain that penetrates through the seams is then drained out of the assembly through a 3” air cavity and building drainage plane (2-ply asphalt impregnated building paper). Air Control: The roof’s air barrier system is again primarily provided by plywood sheathing with taped seams. As previously mentioned it is critical that the exterior sheathing be properly sealed at the joint between the roof and the wall construction with a tapped and lapped membrane.
Figure 3.2.4 Water Content of XPS Insulation in the Roof Assembly
Figure 3.2.5 Water Content of Plywood in the Roof Assembly
Figure 3.2.6 Water Content of Cellulose Insulation in the Roof Assembly
Figure 3.2.7 Total Water Content of the Roof Assembly
Thermal Control: Similar to the wall assembly, heat transfer within the roof is controlled by providing two different layers of insulation. The primary layer is 16” of dense-pack cellulose blown into the roof joist cavity. Outboard of this, a 3” layer of XPS insulation is then installed on the top of the plywood sheathing to provide additional insulation and reduce thermal bridging of the roof joists. WUFI results suggested that a hygrophobic material was necessary (such as XPS) for the exterior insulation because hygroscopic materials accumulated water, endangering the exterior sheathing. Vapor Control: An interior vapour barrier is avoided in the roof assembly due to the vapour retarding properties of XPS. This strategy ensures that water vapour cannot accumulate within the roof. Moisture that enters the assembly can dry both inward. The ventilated air gap within the assembly will still accelerate the drying process. WUFI: Simulation results show the total water content of the roof assembly decreases over the three year period of investigation. This indicates that the roof has adequate drying potential and that water content will not accumulate within critical components in the roof.

D. INDOOR AIR QUALITY EVALUATION 4.1 APPROACH TO IAQ
4.2 AIR FILTRATION & VENTILATION DETAILS
Our building will ensure high levels of indoor air quality (IAQ) firstly by reducing pollutants from indoor sources through appropriate material selection, secondly by ventilating the space, and thirdly by limiting the entry of outdoor pollutant by filtering outdoor air used for ventilation. As such the building was designed to meet ASHRAE 62.2 guidelines for mechanical ventilation, the EPA’s Indoor AirPlus checklist, and LEED Homes Platinum certification Indoor Environmental Quality category (achieving 19 credits).
For air filtration and ventilation the Dual Core HRV3-300 (Y2144) is specified with a MERV 8 filter [1,2]. According to ASHRAE 62.2 both residential units will require ventilation of 37.5 cfm, and according to ASHRAE 62.1 the commercial space will require ventilation of 139 cfm. Therefore, with a whole-house mechanical ventilation of up to 214 cfm the Dual Core HRV3-300 is adequate for supplying fresh air to the entire building.* The HRV meets the DOE Zero Energy Ready requirements with a SRE > 75%. See Section I, Construction Documents, for HVAC Mechanical plans.
4.3 EPA INDOOR AIRPLUS CHECKLIST Materials
Moisture
Pest
In order to create a healthy home great care was taken in the material selection, not only for interior finishes, but also for materials used in the construction of the home. Natural materials such as cellulose insulation, wood flooring with naturals oil wax finish (AFM safecoat) [3], woodfiber board sheathing (SONOclimate ECO4) [4], wood siding and clay plasters for the exterior finish were selected because of their low embodied energy and low toxicity.
In order to control moisture through the slab 4” of XPS insulation and 6” of aggregate will be specified to provide a capillary break and drainage. All of the flooring in the house is comprised of hard-surfaces (wood flooring and polished concrete). Lastly, all piping through interior walls is well insulated to prevent condensation.
Corrosion-proof screens are to be installed at all exhaust and intake vents.
For interior finishes we have specified no-VOC paint from AFM safecoat. The paint contains no toxic ingredients and does not offgas. Eco-Bond adhesives will be used as an alternative to conventional caulking. Eco-Bond contains 100% non-toxic ingredients with no solvents and has zero VOCs offgassing during the curing process [5]. Finally, for drywall applications, Murco’s hypo-allergenic M100 Drywall Joint Compound is specified [6]. This product is made with inert fillers, natural binders, and contains no VOCs.
Combustion Pollutants No fuel-burning appliances will be present in the house. Carbon monoxide alarms are to be installed in each sleeping zone.
Radon Approved radon-resistant features are required to be installed in Radon Zone 1 homes, with predicted average indoor radon screening level greater than 4 piCi/L. Radon-resistant features include an aggregate layer below the slab allows the soil gas to move freely underneath the house, polyethylene sheeting as well as sealing and caulking all openings in the slab prevents soil gases from entering the home, and a vent pipe from the aggregate layer allows gases to be vented above the roof.

E. SPACE CONDITIONING DESIGN + ANALYSIS 5.1 MECHANICAL SYSTEMS & PERFORMANCE GOALS
A Variable Refrigerant Flow (VRF) system was selected for heating and cooling to make most advantage of the overall design strategy that includes passive heating and cooling features. The goals for this system include: • Flexibility in space conditioning • Increased occupant comfort • Reduced energy consumption • Minimal architectural impact • Reduced emissions This technology is gaining in popularity in commercial and institutional buildings in Canada, but is relatively uncommon in residential structures due to the increased initial cost. However VRFs have some unique properties that make them relevant to energy efficient home design, notably their ability to redistribute heat throughout a building that is simultaneously using heating and cooling. The VRF system will be composed of one outdoor (condensing) unit as well as eight indoor (evaporator) units. Advances in VRF technology now also allow a domestic hot water heat pump system to be run off the same refrigerant loop as the rest of the indoor units. Electric
Comfort The desired flexibility described above is also important to resistance heating will be used when temperatures go below meet our goals in relation to occupant comfort. ASHRAE the cut-off point for the VRF condensing unit (-4F), which 55-2010 set out a path for achieving acceptable thermal occurs approximately1.2 days per year (based on a 30-year comfort levels through an adaptive strategy. This adaptive average [1]). Ventilation will be provided by a dedicated outdoor air system (DOAS), and exhaust air will run through a strategy relies on “occupant-controlled” features, which have heat recovery ventilator (HRV) to temper outdoor air before it been shown to improve occupant comfort. However occupantcontrolled features (like operable windows), can add a certain reaches conditioned spaces. about of unpredictability and variation between spaces. Many mechanically systems with less flexible zoning have difficulty Flexibility accommodating these differences. Our strategy for occupant VRF systems are able to meet different space conditioning comfort also includes maximizing natural daylighting and requirements in each of the building’s residential units 8 zones, passive ventilation. These features also come at the cost including simultaneous heating and cooling. These features are of higher variability in zone space conditioning loads. As important in an envelope-dominated building that integrates stated above a VRF system is more adept at providing space passive conditioning strategies. The fenestration necessary conditioning under various conditions. for passive solar heat gains and natural ventilation can also contribute to temperature fluctuations in different parts of the Energy consumption house at different times. VRF systems combine the energy performance of high COPs, common to heat pump systems, with the benefit of varying

refrigerant flow to achieve significant energy savings above conventional systems. In fact VRF systems are predicted to have ~40% increased efficiency over comparable unitary heat pump equipment due to the increased efficiencies in partial-load conditions [2]. Furthermore the VRF systemâ&#x20AC;&#x2122;s capacity to redistribute heat within the building will allow for further energy savings. This characteristic will be maximized by using a single VRF system for the entire building, which will make use of different heat gains across the day from the east and the west facades. The following output (Figure 5.1.1) from our DesignBuilder model shows heating, cooling and (DHW) demand across the year. Times when simultaneous cooling and heating demand as well as simultaneous cooling and DHW demand will produce additional energy reduction as heat is redistributed. Table 5.1.2 shows the estimated energy consumption of a VRF system compared to a typical furnace. These figures do not incorporate potential additional gains from heat redistribution that would not occur in a unitary heat pump system. Reduced Service Space VRF systems reduce the distribution space requirements significantly, allowing for the same ceiling heights to be achieved with a much smaller building (approx. 3â&#x20AC;&#x2122; or 10% of
the total building height), resulting in savings of approximately $5,500 in building envelope costs. As well the entire VRF system uses approximately 45 sqft of space for a single mechanical room, containing the DHW and HRV. A natural gas furnace system would likely require an individual furnace and DHW tank for each unit amounting to nearly 135 ft2 of floor space dedicated for mechanical services. Considering that total cost amounts to $283/ft2, any additional space that can be added to living or commercial space will add tangible value to the building.
5.1.2 shows that emissions of CO2 equivalent can be reduced by more than a half, from 6.1 tons to 2.7 tons by using a VRF system. The values used for CO2 emissions associated with energy consumption are 0.07 lb eCO2 / kBtu for electricity and 0.12 lb eCO2 / kBtu for electricity [4,5].
Emissions VRFs allow for exclusively electric mechanical systems, thus the ability to reduce emissions over a natural gas furnace. Relying on electricity will not necessarily reduce emissions. In many areas of North America the electricity grid relies heavily on coal and other fossil fuels for electricity generation. Ontario on the other hand has done an impressive job over the last 20 years to reduce its reliance on fossil fuels [3]. Figure 5.1.3 shows the energy use mix of the Ontario power grid as of 2013. The low figure of 13% fossil fuel generated electricity makes a strong case to avoid using a natural gas heating system in the building to avoid additional emissions. Table

5.2 SPACE CONDITIONING, VENTILATION DEMAND + EQUIPMENT SIZING Equipment Selection and Integration The system is designed to provide outdoor air in accordance with the ANSI/ASHRAE 62.1 and ANSI/ ASHRAE 62.2. System distribution follows best practices as determined by SMACNA, ASHRAE, NFPA, CSA standards and local codes. Energy and load modeling was used to determine zone heating and cooling loads and ventilation loads, thus informing the VRF and HRV equipment selections. The Mitsubishi City VRF system has been chosen more specifically, the Multi Line R2 Series PURY-P72TJMU-A outdoor unit (80MBH heating and 6-ton cooling) with eight indoor units: two City Multi PFFY-P06NEMU-E (floor mounted), and six City Multi PKFY-P06NBMU-E2
(wall mounted). The floor-mounted units will be located in each of the residential units on the third floor while wall mounted units will serve the remaining zones. The HRV is a Lennox Dual Core HRV3-300 (Y2144) with 214 cfm flow (37.5 cfm per residential unit per ASHRAE 62.2-2007 and 139 cfm for the commercial unit per ASHRAE 62.1-2007). To optimize occupant wellness and comfort, supply air is distributed primarily to living and sleeping spaces. Sanitary exhaust is pulled from washrooms. This unit maintains positive pressure in the outdoor air stream to avoid odor migration from the exhaust.

F. ENERGY ANALYSIS 6.1 ENERGY EFFICIENCY STRATEGY
Energy efficiency was considered from the beginning of the building design process. For example, a relatively compact massing was chosen with a longer east-west axis. As well, the roof is designed in such a way that more surface area is facing south to provide additional space for energy generation. Immediately, our (PV) capacity relative to our energy use is limited by our overarching goal to densify the project’s urban setting. Adding additional occupied area will increase energy consumption of the building, while potential area available for energy generation will remain the same. However in relation to energy efficiency, densification is also a way to minimize the energy load per occupant through shared walls and opportunities to share services. So while density reduces the energy consumption per occupant, it increases the difficulty of reaching net zero for the entire structure. The glazing on the building was designed carefully to maximize energy savings while balancing many other concerns.Windows
can reduce heating energy required through passive solar gains, reduce cooling energy required by encouraging passive ventilation, and reduce electricity use by providing natural lighting. However, they can also increase heating energy required by reducing the thermal resistance of the envelope, and increase cooling energy require by allowing unwanted solar gains. To manage these concerns glazing was focused on the south façade. South facing glazing will maximize winter solar gains, while appropriate shading will block unwanted summer heat. An in-depth lighting analysis was also performed to maximize daylighting and to help develop the shading and glazing design. Some operable north-facing glazing was included to facilitate cross ventilation. Finally, high performance fiberglass framed windows with triple pane insulated glazing units (IGU) were specified to minimize the impact the glazing would have on the envelope’s thermal resistance.
conditioning requirements between zones. To address this we specified a variable refrigerant flow (VRF) mechanical system with high flexibility. VRF systems condition zones independently and can even heat and cool simultaneously. The high (COP) of the VRF system and its unique ability to redistribution of heat within the building (even to the (DHW) system) allows for significant energy savings. Unfortunately the performance of these systems is limited by Toronto’s climate, as temperatures get colder the COP reduces and finally the system cuts-off at -4 °F, below which electric resistance heating will be needed (approximately 1.2 days per year). Furthermore, Toronto’s harsh climate (20 °F to 70 °F) requires significant levels of insulation and increased air tightness to minimize space conditioning energy use. Both of these (increased insulation and increased air tightness) can have negative effects on air quality. To remedy this, outdoor air must be brought in and conditioned. Passing it through an HRV will reduce energy consumption associated with this delivery.
Unfortunately, these features can also cause variability in space
6.2 ENERGY MODELING Alongside REM Rate, DesignBuilder was used to gain a more accurate understanding of the building’s performance. The advantages of this software include the ability to model multiple zones, designate non-residential spaces, create detailed occupancy and equipment schedules, and control lighting. DesignBuilder enables users to create a 3D model facilitating the designation of window overhangs, placement and size. DesignBuilder is a graphical interface that uses EnergyPlus simulation engine (developed by NREL and DOE) as a backend [1]. Results generated by REM/Rate are used exclusively for verifying the accordance of the home to the Race to Zero competition guidelines (in regards to HERS ratings).

6.3 RENEWABLE ENERGY SYSTEMS Compliance with Renewable Energy Ready Homes guidelines Given that several preconditions are met, buildings are required to be renewable energy ready in order to qualify for certification under the DOE Challenge Home program. One such precondition is a minimum annual solar insolation. Based on PVWatts, Toronto’s annual solar radiation is 43 kWh/ft2/day. This is below the 54 kWh/ft2/day stipulated by the DOE Challenge Home program. Therefore our building is exempt from these requirements. Regardless of this exemption a PV array is proposed for this project to take advantage of Ontario’s generous incentives. The proposed location, area, azimuth and tilt can be seen on the Figure 6.3.3. Based on EPA’s online site assessment tool, more than 75% of the optimal solar potential is achievable on the site. A solar shading study, using an industryaccepted sunpath tool, shows that the array is never shaded by adjacent buildings or trees. The result of these analyses indicate that this site is a good candidate for a PV systems. The EPA’s Solar Photovoltaic Specification, Checklist and Guide was used to design the array, it consists of 34 CS6P-260P panels from Canadian Solar [4]. The Sunnyboy online tool is used for inverter sizing [5]. The array is designed with a two foot setback from roof edges and all panels are designed to be accessible for future maintenance. As specified by OBC2012 a principal load factor (safety factor) of 1.4 is applied to the roof’s dead load. The current roof’s dead load is 30 lbs/ft2 therefore the roof has the capacity to hold 12 lbs/ft2 extra load which exceeds the 6 lbs/ft2 required for the PV system. Because the roof is steeper than 3:12 a permanent roof anchor fall safety system compliant with ANSI standard A10.14 is required to provide adequate protection to installers. A dedicated space for a 4’ x 4’ plywood panel backing for mounting the inverter, meters and disconnects (isolators) is proposed on the west facade. The area will be clearly

labeled. The 4’ x 4’ plywood sheet should be fastened to the wall studs and mounted so that its center is about 4.5 feet above grade. It must be accessible from the exterior so that workers from the local utility can shut it off in case of grid maintenance. The panel has to be protected from direct sunlight and extreme weather conditions. According to microFIT requirements a parallel connection is also required. The electricity generated by the PV will not be used on-site therefore connection to the main electrical panel is not required. A 1” metal conduit leading from the array to plywood panel will be installed. The conduit will be labeled properly to show its intended use.

An education package consisting of a copy of the Renewable Energy Ready Homes REHR specification guide, completed RERH PV checklist, all necessary architectural drawings, shading study, code-compliant load documentation, as well as electrical drawings and riser diagram must be provided to the owner. The PV array size will be 8.84kW (30.16 kBTU/hr) and will generate 10339 kWh per year (35.278 kBTU/year). The total installation cost for this system is approximately $31 000. Considering the assumptions shown in Table 6.3.1 the system will payback in less than 9 years (a 11.5% return on investment).

G. FINANCIAL ANALYSIS 7.1 BUILDING COST ESTIMATE Financial Goals One of the goals of this project was to demonstrate a fully applicable model for a high performance home that also is relatively affordable. In Toronto the goal of affordability can be difficult. While accurate statistics are difficult to find, recent discussions with real estate agents indicate that a single detached home (approximately 1,500 ft2) in a similar location costs nearly $800,000 ($533/ft2), and news media reports that the detached home average in Toronto has surpassed the $1,000,000 mark [1]. Condos on the other hand are cheaper, partially due to the incredible amount of new units being added (35,000 units are expected in 2015 [2]). New units have an average size around 800 ft2 at around a cost of $475/ft2, totaling around $380,000. The Corner House will provide a middle ground between the options typically found in the Toronto market. Each of our two residential units will be 1,500 ft2 and financial analysis shows that they will cost around $435,000 ($280/ft2).
The construction cost was calculated primarily with RSMeans. A detailed cost breakdown for each section is available in the Appendix. The summary shows the construction cost amounts to approximately $83/ft2. When including the cost of land, sales tax (13%) and overhead and profit for the developers (20%) the final cost amounts to approximately $283/ft2. As well our cost breakdown only shows a $20,000 premium for our high performance features, which amounts to around 1% of the total project cost. All full breakdown of all costs is available in Appendix G. It should be noted that RSMeans is only a cost estimation tool, and real cost for a project such as this can vary significantly [6]. In some cases it was observed that predictions with RSMeans were way off what could be considered reasonable for the Toronto area. As well RSMeans occasionally lacked the information for certain high performance products. In these cases data was sourced directly
Other Developer Fee Sales Tax
26% Land
Total overview of costs from contractors or retailers. When possible material costs sourced from outside sources were combined with labour time estimations from RSMeans to determine a relatively robust local cost figure. A land cost was calculated with various sources of information. A property assessment from 2009 listed the property cost at $379,000. Using real estate listings we were able to identify homes in the area that had been sold in both 2009 and 2014. From these resaleâ&#x20AC;&#x2122;s we were able to calculate on average appreciation of 34% in housing costs during this period, resulting in a land cost of $511,000. The cost premium associated with specific building elements is discussed below: HVAC/DHW The bulk of the high performance premium is associated with the mechanical system. Besides increased energy performance, the specified system occupies much less interior space (45 ft2 compared to 135 ft2 for a typical natural gas furnace system). At a total cost of $283/ft2, 90 ft2 of additional occupiable space is a tangible benefit to the building.

Exterior Wall Perhaps the most surprising result of the financial estimate is the relative cost effectiveness of the high performance wall. New requirements in Ontario require at least 3â&#x20AC;? of (XPS) as well as fiberglass batts in the stud cavity to meet code. The cost effectiveness of wall systems that use expensive materials like XPS cannot compare with the cost of wall systems that use inexpensive materials like cellulose. Increased height required to accommodate large distribution air ducts (associated with a forced air mechanical system) in the standard performance house is also expected to increase envelope costs by approximately $5,500.

High Performance
High performance (IGUs) with fiber glass frames are now available from Ontario manufacturers at significantly lower costs than comparable wood frame products.
Roof The increased cost of the high performance roof assembly is primarily due to extra cost associated with insulation. Both systems require XPS to achieve acceptable hygrothermal performance.
Mortgage Affordability Mortgage calculations indicate that the family would require a household income of approximately $72,000. The average household income for a family in this neighbourhood is $74,820 [3]. This declines for private households as well as single parent families to $64,840 and $39,046 respectively.
Life Cycle Cost Total cumulative life cycle costing shows that over the 30 year mortgage the high performance home’s cumulative life cycle cost is approximately $24,000 more than the lifecycle cost of the standard home. This is primarily done to extremely low prices for natural gas.
7.2 AFFORDABILITY ANALYSIS Assumptions • The Toronto property tax rate is 0.72% for multi-residential properties and 2.89% for commercial properties [4]. Assuming the entire building is assessed at $1,150,000, and that unit 1 is has a commercial occupant the total property tax per year will be $14,178.25 Unit 1 $ 7,716.60 Unit 2 $ 3,230.83 Unit 3 $ 3,230.83 Total $14,178.25 • Insurance estimated at $5,000 • Utilities estimated at $2,097. This is based on total energy use and a flat electricity rate of $0.09/kWh [5] • Down payment 20% ($230,184.16) • Mortgage rate 4.5%

H. DOMESTIC HOT WATER, LIGHTING + APPLIANCES ANALYSIS 8.1 DOMESTIC HOT WATER DESIGN
The building’s domestic hot water (DHW) system is integrated with the mechanical system. This is made possible by incorporating a heat pump water heater into the building’s (VRF) refrigerant loop. This system will allow heat rejected from living spaces (during the cooling season) to contribute to the water heating process. As well a single DHW tank is specified for the entire building, this will reduce the amount of heat lost from standing hot water. A Mitsubishi Hydra-Dan Booster hot water heat pump is sufficient to satisfy the demand of the entire building (10-20 people) [1]. For easy maintenance, both the mechanical and hot water unit will be centralized in one area. This mechanical room is located on the ground floor NW corner. The pipe sizing and placement were designed to meet all the requirements outlined by EPA WaterSense. The water faucet and fixtures are WaterSense approved. The pipes are designed as a whole-house manifold system. These systems are ideal for spacious layouts with multiple fixtures such as ours. A whole-house manifold does use more piping, however it is more water efficient than the trunk and branch system due to its smaller pipe sizes. See Section I for Plumbing Plans Based on the longest distribution line in the house (from the ground floor mechanical room running to the east third floor East unit kitchen sink) our house will meet the relevant EPA specifications for hot water standing in pipes, and hot water delivery time. This line is composed of a 4 ft of manifold of 1/2” PEX pipe (with 1.18 oz/ft) and 46 ft of distribution line in 3/8” PEX pipe (with 0.63 oz/ft). It will store 0.26 gallons (significantly under EPA’s mandated maximum of 0.5 gallons). As well based on a calculated wait time of 7.2s and assuming a flow rate 2.2 gpm, approximately 0.26 gallons will be delivered before hot water arrives to the fixture, below EPA’s mandated 0.6 gallons. Our building’s landscape site is less than 1000ft2, so it is exempt from the EPA landscape design criteria. However, to help alleviate surface runoff going into the local storm water system, the house will incorporate permeable paving and collect rainwater for irrigation. The rainwater from the roof will be diverted into a 350 gallon rain barrel via a downspout. This barrel will be located on the west side of the building.
8.2 OWNER OPERATION AND MAINTENANCE CHECKLIST Occupant 1. Remotely regulate the water temperature (as needed)
Personnel 1. Check the temperature
2. Set to ECO mode for energy savings, (allows outlet water temperature to adjust based on the ambient air temperature) (as needed)
2. Complete a water quality test
3. Set to anti freeze mode to help prevent water pipes from freezing (when not in use during winter) 4. Check and clean the water strainer (every 3 months) 5. Clear off any dust or debris surrounding unit (every 3 months) 6. Inspect for leaks within pipes (every 3 months) 7. Check that the valve can be opened and closed (annually)

3. Inspect anode, drain lines and electrical wiring
8.3 APPLIANCE DESIGN Appliances The control strategy for reducing energy use from appliances primarily relies on specifying energy efficient models. Clothes dryer, refrigerator and stove are the main contributors to appliance annual energy consumption. Assuming a common set of appliances for a family of four, EnergyStar’s product database and the DOE’s Energy Data Book were used to determine the energy consumption for each residential unit. By choosing energy and water efficient products for major appliances it is observed that a 400 kWh reduction in annual energy usage can be achieved, for a total of 3,000 kWh/yr (342.5 W). This is equivalent to an equipment power density (EPD) of 0.22 W/ft2. As well standby energy consumption accounts for 5%-10% of residential electricity use. To minimize standby power consumption each unit will be equipped with a main shut-off switch to disconnect electricity from all outlets (except the refrigerator). This switch can be used on a daily basis during the hours the home is unoccupied. This strategy can reduce approximately two thirds of the energy consumption associated with routers, and reduce energy consumption for other appliances like TV, computers, game consoles and audio/video devices. Further reductions depend heavily depend on occupant behaviour.

Daylighting Day lighting was optimized to provide improved occupant comfort as well as to reduce electricity consumption. Tall windows and high ceilings on the third floor let light deep into occupied spaces. Reduced east and west glazing reduces glare and increase the quality of the daylighting. Shading devices on the south faรงade are used to avoid direct sunlight penetration into during the cooling season. Slatted window awnings provide shading to the retail space as well as bedrooms on the second floor. South facing windows on the third floor are shaded by the soffit.
Electrical Lighting In order to ensure optimal visual comfort and adequate task lighting, electrical lighting design simulations were completed. Illuminance levels were designed to reach 100 lux as required by IESNA for basic tasks. Additional illumination is provided where necessary for example in front of kitchen in the retail area. Figure 8.4.1 shows illuminance levels at the work plane height in each space. EnergyStar certified energy efficient lighting fixtures were picked for this building. This includes a combination of decorative pendant, recessed down lighting and track lighting.
Lighting modeling was performed to assure that light levels are between 300-3000 lux in more than 75% of the regularly occupied spaces at 9am and 3pm on both equinoxes (March 21st and September 21st). The results of the modeling are shown in Figure 8.4.2, Figure 8.4.3 and Figure 8.4.1.
The residential entrances at the back of the building are equipped with motion activated sensors to provide lighting at night only when necessary. An all-off switch is located at the home entrance, occupants can use this switch to ensure that no light remains on while nobody is home.

J. INDUSTRY PARTNERSHIPS
From the beginning of the project our team identified a goal (above and beyond specific performance goals for the building) to design something relevant to Toronto’s housing market. However, we also recognize the difficulty of shifting typical practice. To leverage the impact that this design proposal could have we sought out several partnerships with industry professionals that could help realize improvements to construction industry practices, and even potentially realize the construction of the proposed house itself. Chris Magwood – Sustainable Builder, Author, Educator Chris Magwood was one of our leading external advisors on the Corner House project. He provided support on critical issues such as constructibility, affordability, and natural material selection. Currently operating out of Peterborough Ontario, Chris is the Executive Direct of the Endeavour Centre, a non-profit sustainable building school, where he teaches a focus on sustainable building through natural, organic materials [1]. He has written several books on straw bale construction, and recently published a book called Making Better Buildings: A Comparative Guide for Sustainable Construction. He is currently interested in showcasing models for ecological, affordable, energy efficient homes. The Living City Campus, Kortright Centre- A BRE Canada Innovation Park The Kortright Center is Ontario’s premier environmental and renewable energy education and demonstration centre and home also to a BRE Innovation park [2]. The Innovation Parks is designed as a showcase community to demonstrate and test innovative solutions to sustainable building and neighborhood development. The ultimate goal of this facility is to help accelerate the commercialization and adoption of green building techniques. Each building constructed in the innovation park must meet the guidelines for at least one of the following sections: 80% Energy Reduction, Passive House, Envelope First, R2000 Net Zero, Water Efficiency, Modern Construction Methods, Low Impact Construction, Design for Deconstruction, Interactive Building, First Nation Housing, Assisted Living and Health, Off Grid Design, Affordable Sustainability, Refurbishment, or Small Scale Commercial. Working alongside Chris Magwood as a potential builder of the project, the Corner House was designed to meet the guidelines for at least one of the criteria (although it will likely meet the criteria for several). Particular interest was expressed in pursuing the Low Impact Construction, Affordable Sustainability, and Envelope First requirements.
