IN-1: Innovation 1

Pilikan House Pilikan (pronounced "Bill-ee-gun") is derived from the Mi'kmaw words for "new house". The name represents a new way of thinking about healthy, sustainable residential development. This house is a "living lab" and demonstration site where the next generation of residential construction professionals can learn how to incorporate sustainability into their work. It is designed to be an affordable and practical home to show home-owners how sustainable design and energy-efficient options can be within their reach. Pilikan is a hands-on learning tool for the students in NSCC's Energy Sustainability Engineering Technology (ESET) program, as well as a research tool with 30 monitoring and control points to track energy consumption. To demonstrate how energy efficient this house is, during the Winter (February 2013), when the temperatures were approximately – 15 degrees Celsius (5 degrees Fahrenheit), the heat was shut off. The coolest temperature recorded while the heat was shut off was 15 degrees Celsius (59 degrees Fahrenheit). Highlights of the Energy Efficiency of this house are listed below. 1. Pilikan Energy Efficiency Ratings Pilikan is certified as an R-2000 house and achieved an Energuide rating of 91 – requiring little to no purchased energy. A rating of 100 is the maximum efficiency score as defined by Natural Resources Canada. Typically, R-2000 homes need 30% less energy to operate than conventional new homes. Airtightness is critical to building performance and energy efficiency. The blower-door test on Pilikan House resulted in a reading of 0.6 ACH (Air Changes/Hour). A typical home would measure 1.5 ACH. 2. Frost Protected Slab The perimeter of the slab has an insulated skirt which prevents frost from penetrating the soil underneath, eliminating frost heave. This results in superior energy performance, while reducing the materials used for the foundation. 3. Double Stud Walls The walls in this house are essentially two thin walls separated by a space. This separation eliminates thermal bridging, where heat is lost through the home's wood framing. 4. Extra Insulation The entire house is insulated well beyond building code requirements so it loses very little heat in winter and gains very little heat in the summer. Walls: R44 Ceiling: R80 Slab: R32 5. Solar Hot Water Using the energy from the sun, solar thermal panels heat the water used by the occupants of the house. 6. Heat Recovery Ventilator (HRV) The locally-built, highly-efficient HRV unit provides high-quality indoor air. The unit's motor can reduce energy consumption by 25%. It has a unique damper system and its large-sized core reduces fan noise, increases heat recovery efficiency and lowers power consumption. 7. Triple Glazed Windows With a higher insulation level than single or double-glazed windows, these windows reduce heat transfer across the glass surface, increasing comfort and energy savings. 8. Solar Photovoltaic (PV) Power These PV cells capture the sun's energy and convert it into usable electricity. They do not require sunlight and can actually generate electricity on a cloudy day to power lights, electronics and everyday appliances. 9. Passive Solar Heating Pilikan House was built facing South, allowing for optimum solar gain. The windows let in natural light which helps increase the home's ability to capture and store thermal energy in the form of heat.
