How Can I Build an Energy-Efficient Home? Avoid These 5 Common Pitfalls in High-Performance Construction
Building an energy-efficient home is an exciting journey, and the rewards go well beyond saving on power bills. With the right construction practices, a well-designed home can offer year-round comfort, improved indoor air quality, and a significantly reduced environmental footprint. However, the path to a high-performance home isn’t always straightforward, and certain missteps can stand in the way of achieving the efficiency and comfort you want.
To help you navigate this process, we’ve outlined five common pitfalls in energy-efficient home design and construction, along with ways to avoid them.
1. Overlooking Passive Solar Design Principles
Passive solar design is a powerful tool in energy-efficient home building, using the sun’s natural warmth and light to keep your home comfortable. A well-thought-out Passive Solar Design Building Orientation can drastically reduce your reliance on heating and cooling systems.
What to Avoid:
Don’t place windows and living spaces without considering the orientation of your home. Improper placement may result in missed opportunities for natural solar heating and passive cooling.
What to Do Instead:
Focus on Passive Solar Energy techniques, like placing large, energy-efficient windows on the northern side of your home (if you’re in the southern hemisphere) to capture winter sun while using shading to block the summer heat. Discuss these ideas with your architect or builder early on so your home’s design maximises both sunlight and shade at the right times.
2. Skimping on Insulation
In high-performance homes, insulation does more than just keep the temperature comfortable. Proper insulation forms a Thermal Barrier that helps maintain a stable indoor climate and reduces energy loss, making it essential for energy-efficient homes.
What to Avoid:
Don’t choose cheaper, minimal insulation that only meets basic code requirements. Inadequate insulation can lead to cold spots, higher heating and cooling costs, and compromised comfort.
What to Do Instead:
Invest in Continuous Insulation across the entire building envelope. Look for thermal insulation materials with high Thermal Resistance, especially in key areas like walls, ceilings, and floors. Remember, insulation quality matters as much as quantity, so opt for materials that are suited to your climate for the best results.
3. Ignoring the Importance of Airtight Construction
Airtightness is essential for controlling airflow, preventing heat loss, and maintaining a consistent indoor environment. In a high-performance home, Airtight Construction works hand-in-hand with controlled ventilation to keep fresh air in and pollutants out.
What to Avoid:
Don’t overlook air sealing around doors, windows, and electrical outlets. Leaks here can let conditioned air escape and unfiltered outside air enter, making it harder to maintain energy efficiency and indoor comfort.
What to Do Instead:
Prioritise quality Airtight Materials in construction, and ensure your builder performs a Building Air Leakage Test to identify any gaps or leaks. Proper air sealing also means integrating Airtight Doors and High-Performance Windows to minimise unwanted airflow and enhance energy savings.
4. Choosing Low-Quality Windows and Doors
Windows and doors can account for a substantial portion of energy loss in homes. Without the right materials and glazing, these areas become weak spots in energy-efficient home design, letting heat escape in winter and enter in summer.
What to Avoid:
Avoid single-glazed or low-performance windows that lack insulation properties. These can cause temperature fluctuations and lead to increased energy usage.
What to Do Instead:
Opt for High-Performance Windows and Doors with multiple glazing layers, such as double or Triple Glazing. High-performance energy-efficient windows and doors are designed to enhance thermal performance, block outside noise, and help maintain a comfortable indoor environment year-round.
5. Neglecting Moisture and Ventilation Control
An energy-efficient home is also one that provides a healthy, comfortable indoor environment, which means controlling moisture and maintaining adequate ventilation. Without proper Moisture Control, homes can develop mould, humidity issues, and indoor air quality problems.
What to Avoid:
Don’t rely solely on natural ventilation (like opening windows) for air quality. This method alone can’t control indoor humidity, and in extreme weather, it may even compromise energy efficiency.
What to Do Instead:
Incorporate a Heat Recovery Ventilation (HRV) or All-Electric Home System for proper air exchange. These systems work with your home’s airtight construction to circulate fresh, filtered air while managing humidity levels. Additionally, moisture barriers and humidity control solutions in walls and ceilings will protect your home from potential moisture buildup and improve indoor air quality.
