  5. Parking: Provide accessible parking spaces close to the entrance of your home. These spaces should be larger than standard parking spaces to accommodate wheelchair vans and other mobility aids.

Meeting Construction Requirements

To build a home that meets RT 2020 standards, you must adhere to specific construction requirements. These requirements cover various aspects of your home, such as the building envelope, insulation, ventilation, and heating systems. Some key requirements include:

  1. Building envelope: The building envelope is the outer shell of your home, which separates the interior from the exterior environment. To meet RT 2020 standards, your home’s envelope must be well-insulated and airtight to minimize heat loss and maintain a comfortable indoor temperature.
  2. Insulation: Your home’s walls, roof, and floors must be adequately insulated to minimize heat transfer. This can be achieved by using high-quality insulation materials, such as mineral wool, cellulose, or expanded polystyrene.
  3. Ventilation: Proper ventilation is essential for maintaining good indoor air quality and preventing moisture buildup, which can lead to mold and other health issues. Your home should have a well-designed ventilation system, such as a heat recovery ventilator (HRV) or an energy recovery ventilator (ERV), which can help to maintain a healthy indoor environment while maximizing energy efficiency.
  4. Heating systems: Your home’s heating system should be energy-efficient and capable of maintaining a comfortable indoor temperature. Consider using renewable energy sources, such as solar panels or heat pumps, to power your heating system.
  5. Windows: Ensure that your windows are double or triple-glazed with low-emissivity (Low-E) coating to minimize heat loss and improve energy efficiency. Additionally, make sure that your windows are properly sealed to prevent drafts.

Adhering to Energy Efficiency Standards

RT 2020 emphasizes the importance of energy efficiency in new buildings. To meet these standards, your home must have a low energy consumption and utilize renewable energy sources. Here are some ways to achieve this:

  1. Passive design: Incorporate passive design strategies, such as proper building orientation, natural daylighting, and shading, to minimize your home’s energy consumption.
  2. Renewable energy: Incorporate renewable energy sources, such as solar panels, wind turbines, or geothermal heat pumps, to generate electricity and heat for your home.
  3. Energy-efficient appliances: Choose energy-efficient appliances, such as ENERGY STAR-certified products, to minimize your home’s energy consumption.
  4. Smart home technology: Use smart home technology, like programmable thermostats, lighting controls, and energy monitors, to optimize your home’s energy use.
  5. Energy performance assessment: Regularly assess your home’s energy performance to ensure that it meets the RT 2020 standards. This can be done by conducting an energy audit or using energy modeling software.
