In the realm of homeownership, knowledge is power. Understanding your home’s energy efficiency is not just about being environmentally conscious; it’s also about making informed decisions that impact your cost of living. The better your Building Energy Rating (BER), the more efficiently your house performs, ultimately leading to lower living costs.
Think of it this way: it’s akin to buying an A-rated washing machine. While it may come with a slightly higher price tag upfront, it will save you money in the long run through reduced energy consumption.
How Do You Determine Your Home’s BER?
When renting or purchasing a home, the BER rating should be readily available and is typically calculated by a BER specialist. If you’re unsure of your home’s BER rating, tools like the An Post Green Hub’s BERWOW Energy Upgrade calculator can provide valuable insights.
To receive recommendations based on your existing BER certificate, you’ll need to provide your MPRN (printed on your electricity bill) and a recent utility bill (from the last 3 months) containing your address and MPRN. Alternatively, you can obtain recommendations based on the BER information of homes similar to yours.
Additionally, the An Post Green Hub offers a free home energy assessment in partnership with SSE Airtricity. A specialist will visit and survey your home, providing advice on your rating and options to enhance its energy efficiency.
Common Methods to Improve Your Home’s Energy Rating:
- Insulation: Enhance your home’s insulation by ensuring your attic has a 400mm insulation depth and consider insulating external walls. Options include internal dry lining and cavity bead insulation, along with insulating the floors.
- Upgrade Your Windows: Triple-glazed windows, installed with airtightness foam or tape to ensure proper sealing, can significantly improve your home’s energy efficiency and overall comfort.
- Heating Your Home: After creating an efficient thermal envelope for your home, focus on heating methods. Consider renewable energy sources such as air-to-water heat pumps for heating and hot water or solar panels to provide hot water and generate electricity for a heat pump.
Is Retrofitting Expensive?
The cost of retrofitting varies based on the scope of work required and the unique features of your home. The An Post Green Hub provides a complimentary home survey in partnership with SSE Airtricity to assess your retrofitting needs without any obligations. This survey equips you with precise information tailored to your home, enabling you to make well-informed decisions within your budget.
Retrofitting can be carried out incrementally, allowing you to plan and budget for improvements over time. It’s an investment in your home’s future, offering long-lasting benefits in terms of thermal comfort, overall comfort, and reduced energy bills.
Is Retrofitting Disruptive?
Certain retrofitting elements can be done without significant disruption, such as improving attic insulation, adding external wall insulation, cavity beads, and window replacements. Other changes, like internal dry lining or heating source upgrades, may involve more disruption, but experts can guide you on managing these aspects while you continue to live in your home.
Is It Suitable for All Homes?
Generally, homes built before 2009 tend to lack adequate insulation and airtightness. These older homes often rely on traditional heating methods and are prime candidates for thermal improvement, window upgrades, and adopting renewable heating and hot water sources.
Additional Benefits of Retrofitting:
Beyond energy bill savings, retrofitting your home enhances its thermal comfort and overall livability. By eliminating drafts, dampness, and cold spots, you improve your home’s health and well-being. Furthermore, retrofitting offers you the chance to restyle your home’s exterior with features like external wall insulation and new window styles, transforming its character and appearance.
In conclusion, understanding your home’s energy rating is essential for cost-effective, sustainable living. Embrace the opportunity to improve your home’s efficiency, comfort, and aesthetics through retrofitting, and reap the long-term rewards.
