In a world where many homes are built with large, west-facing floor-to-ceiling windows, energy efficiency can often be a challenge. These structures are difficult to change in terms of design, but there's still hope. By making small adjustments during renovation, you can significantly improve your home's energy performance and move it closer to being "energy-efficient."
**Coup 1: Add a Seal Strip to Doors and Windows**
If your doors and windows have gaps due to poor manufacturing or installation, you're likely losing heat in winter and letting in hot air in summer. A simple solution is to install a seal strip. This inexpensive and easy-to-install fix can make a big difference in reducing energy waste. Even if you already have one, check it regularly—especially when the weather changes. If you feel a draft, it’s time to replace it.
**Coup 2: Insulate the Balcony Door**
Many homeowners remove their balcony doors during renovation to create more space or simply use an enclosed balcony without installing a door. However, this can lead to higher energy bills. Balconies are typically less insulated than regular walls, and without a door, they become a weak point for heat loss or gain. Experts recommend keeping the balcony door and adding insulation or upgrading to double-glazed windows for better thermal performance.
**Coup 3: Apply Aluminum Foil on the Roof**
Top-floor or end-unit homes often suffer from extreme temperatures. During renovation, consider using materials like aluminum foil on the roof’s inner surface. This low-emissivity material helps reduce heat radiation, making the space more comfortable. You can also apply thermal insulation mortar to exterior walls or paint them with light-colored paint to reflect heat. Installing a 100–150 mm insulation layer on the roof waterproofing is another effective option. Replacing old wooden or metal windows with plastic or double-glazed ones can further enhance energy savings.
**Coup 4: Install Window Shades or Heat-Reflective Curtains**
Adding a window awning or using heat-reflective curtains can help cut down on summer cooling costs. These shades block most of the sunlight before it enters the room, which is more effective than just using regular curtains. Choose curtains with a silver or metallic outer layer and a decorative inner layer for optimal performance. This small upgrade can make a big impact on your energy usage.
**Coup 5: Plant Climbing Vegetation on the Walls**
Planting climbing plants like ivy, wisteria, or morning glory on your walls can provide natural insulation. In summer, these plants block sunlight and absorb heat, lowering the temperature of the outer walls by up to 4–5°C. In winter, the leaves don’t interfere with sunlight exposure. This eco-friendly approach not only improves energy efficiency but also adds beauty to your home.
By taking these small steps, you can transform your home into a more energy-efficient space without major structural changes. Energy-saving doesn’t always require a complete overhaul—it starts with smart, practical choices.
