PREFACE: The objective of this design report is to illustrate on how to maximize the energy efficiency of the Hove Solar Passive residential home and reduce its ecological footprint by implementing sustainable materials and renewable energy sources. The idea is to design a single-

family, passive-solar home that integrates passive solar design principles into the orientation, massing, fenestration and building detailing; and that responds to the microclimatic considerations of the given site.

The home is located in North York, Ontario, Canada, suitable for a single family with three children. Passive homes do not have a negative impact on the environment and can achieve net zero energy consumption. In addition, passive homes require minimum maintenance

compared to traditional homes. This results in significant energy cost savings for the homeowner and simultaneously reduces the carbon footprint. The passive house design approach uses renewable energy sources in lieu of hydro purchased from the grid and natural gas which is

supplied by the gas company. The home is designed to capture the sun’s solar energy via solar panels which is utilized in powering the HVAC, lighting, & various appliances. Furthermore, the southern orientation of the house is a key design consideration which provides maximum solar

heat gain and reduces the capacity of the heating system through passive heating, thus, minimizing the energy consumption. Also, the sun path determines the location of the windows for maximum sunlight exposure. The most frequently used spaces are the kitchen and living room

which will be located on the south side of the home for maximum sunlight. The less common areas including the utility room and washroom are located on the north side. Similarly, the second floor has a similar layout with all the bedrooms facing the south side and the washrooms on

the north side. The staircase is located on the north facing wall.

Materials

Material selection for the passive design home is a critical component to achieve low energy consumption. Implementing the appropriate materials can have a significant impact on the building’s performance. The material

selected for the home will absorb the heat from the sun and act as a thermal mass to dissipate heat when required such as at night time. The thermal mass comprises of the envelope and floors including tiles which will store and

distribute energy. The other flooring material will be recycled bamboo wood fibers. Another sustainable feature is the green roof. It allows to achieve a high thermal insulation R-Value for the roof resulting in minimal heat losses.

The roof will also have photovoltaic panels on the south side of the building. The Photovoltaic panels will generate sufficient energy to power the entire house. The solar panels are on the south area of the roof at an optimal angle of

45 degrees. In addition, solar water heating panels will also be installed to provide hot water heating mitigating the use of natural gas or electricity for domestic hot water.

Solar renewable energy For the HVAC system, a geothermal system will be integrated for heating and cooling. It works by utilizing the ground as a heat source to reject heat in the summer for cooling and absorb heat from the ground

in the winter for heating. A VENTIFLEX PLUS system and ground air-heat exchanger will be utilized. The ground-air heat exchanger will replace the traditional split system air-conditioner. This system reduces the energy

consumption for heating and cooling fresh air. In the summer the air travels through the in ground-air exchanger. The air from the exterior of 30 degrees Celsius reduces to 18 degrees after traveling through the

ground air exchanger. That air is then distributed through mechanical ducts to each room. The system has filters to remove any contaminants and dust particles in the air. In the winter seasons, the ambient air has a

temperature of -18 degrees Celsius which is tempered in the ground air-exchanger the to achieve 0 degrees. The heat recovery ventilator (HRV) will be connected to the in-ground heat exchanger to increase the air

from 0 degrees to the desired room temperature set point. It functions by capturing the latent and sensible heat energy from the kitchen and washroom exhaust and transfers to the supply air to the space, resulting in

energy savings since the supply air does not require to be tempered completely to meet the desired indoor air conditions.

Energy conservation • Another energy conservation feature of the home is the smart controls. For example, it will have a “All-Off” programmable time switch that will be located adjacent to the entrance of the home which will provide the user to control all the interior and exterior lights and set

back during unoccupied hours.

• The massing and the shape of the home has reduced the wall area hence reduced the amount of heat losses.

• The home will be constructed with an airtight envelope with double wall construction which contributes to a more efficient design by approximately 55% more efficient than a standard constructed home. The windows will be triple pane windows with low e-argon filled for

noise and temperature control.


GREEN FEATURES • Rainwater drainage through green roof

• Low flow faucets and fixtures

• Dual flush water saving toilets

• Solar hot water collectors

• Photovoltaic solar electricity panels

• Extended roof-line to block heat from the summer sun

• Natural ventilation design to eliminate the need for air conditioning

• Passive solar design with slate floors to retain solar heat

• Double insulated walls for added warmth, quiet, draft proofing, and durability

• Triple pane windows

• Flexible open design to adapt easily to life’s changes

• Rapidly renewing bamboo flooring and stairs

• Built-in recycling centre

• Low VOC paints and finishes

• Compact fluorescent lights throughout

ADVANTAGES • Positive impact on the environment

• Reduces the total GHG (green house gas) emissions with usage of renewable energy

• Net-zero annual energy consumption

• Reduction in water utility costs

• Airtight envelope

• Solar panel energy production

• HRV (Heat recovery ventilator) system

• Sustainable appliances

Lower cost of home ownership

• Double wall construction, with high level of insulation and triple-glazed insulated windows, contribute to a design that is 55% more efficient than typical new homes

• Water consumption reduced by over 70% compared to the average home

• Architecturally designed window locations optimize the sun exposure to heat the home in the winter while roof-lines provide shade in the summer to keep the house cool

• Uses solar power to generate as much energy as is consumed each year

Empowerment and Convenience

• Convenient energy savings features including “All-Off” switch at the entry that turns off all lights and selected “green plugs” located throughout the house

• Recycling centre in the kitchen and garage for easy access and disposal of recyclable goods

Breathe easy

• Allergens are kept down to a minimum with the use of enhanced air filtering and the elimination of carpets

• Filtered fresh solar heated air is distributed throughout the home by a heat recovery ventilator (HRV) system

• Home is constructed using low toxicity paints and glues

Future flexibility

• Flexible floor plans allow for home design that fit the home-owners needs today and for the future. Additional bedrooms, or home offices are easily accommodated

Other Sustainability Features

• Rapidly renewable resources, such as bamboo flooring used throughout the home

• Incoming water filtration system

• Green House Gas emissions are eliminated as the home generates as much clean renewable energy as it consumes annually


DISADVATANGES • Increased initial cost

• Maintenance of renewable energy systems
