Your home is more than just a structure; it’s where memories are made, and life unfolds. If you own an older house in Christchurch, New Zealand, you know the charm and character it brings. But have you ever considered how you could enhance its comfort, sustainability, and value through renovations or Energy Efficient extensions? At Energy Efficient Homes Ltd, we’re here to guide you on this transformative journey.
Understanding Energy Efficiency Requirements
Before embarking on any renovation project, it’s essential to comprehend how energy efficiency requirements apply to your project. According to the Building Act 2004, any new building work must strictly adhere to the Building Code. However, when it comes to existing buildings like yours, there are specific provisions in place to ensure that energy efficiency is upheld or improved during alterations.
For substantial renovation projects involving older buildings, the new additions must meet current code requirements. This ensures that as your home undergoes transformations, it keeps pace with contemporary standards, providing you with a dwelling that’s both efficient and comfortable.
The Key to Successful Alterations: Assessing Thermal Performance
The heart of any renovation lies in assessing the thermal performance needed for repaired or replaced building elements. Our experts at Energy Efficient Homes Ltd take into account factors such as the element’s contribution to the overall performance and its role within the building envelope. This meticulous analysis ensures that replacements not only maintain but exceed the previous performance levels. Our commitment is to elevate your home’s efficiency, ensuring every aspect of your project aligns with your sustainable living goals.

Seizing Opportunities for Improvement
Renovations and alterations offer unique opportunities to elevate the performance of your existing home. We will advise on what is necessary to achieve maximum energy efficiency whilst taking into consideration your budget. While the Building Act sets a baseline, there are many opportunities beyond that empower you to surpass expectations, creating a home that excels in energy efficiency, comfort, and overall value.

Flexibility and Adaptability: Navigating Changes Smoothly
During the construction process, unexpected circumstances or evolving preferences might prompt changes to your initial plans. Our approach emphasises specifying insulation R-values during the design phase, rather than fixating on particular products, to prevent potential setbacks and delays. Should adjustments be necessary, we can provide guidance on seamless product substitution, ensuring your project remains on track.



Transforming your older home into an energy-efficient haven is not just about meeting regulations; it’s about crafting a more sustainable, comfortable, and valuable living space. At Energy Efficient Homes Ltd, our goal is to be your trusted partner on this journey.
We are here to provide valuable insights and expertise, turning your vision into a reality.
