It doesn't matter how well you design a home to perform… Six stars to 10. Everybody knows, if it is not built to a standard to meet that performance, the energy efficiency potential will not be a reality on the ground. But don't blame the builder; they only build what’s on the plans, and nobody has taught them the construction assumptions of the NatHERS system, or how to build tight with standard construction. Do you know?
This is the second part of a two-part series, by builder, energy rater and director of Positive Footprints Sustainable Design and Construction Jeremy Spencer, looking at what to put on plans to achieve a performance outcome.
This webinar goes over the construction assumptions inherent in the NatHERS system. It also looks at the details to put on plans clearly communicating to the builder what needs to be done so the building meets House Energy Rating report thermal requirements, and performs on the ground as it should.
In particular, we will cover:
• Thermal bridging hot-spots and how to break them
• Common problem spots for thermal performance in the home
• Setting thermography and blower-door-testing criteria for the builder to achieve
• Going beyond the star rating - Technology specification for a net-zero outcome, and
• How to choose a builder you can trust.
For almost 20 years Jeremy has been a registered builder, energy rater and director at Design & Build company Positive Footprints. Positive Footprints have won multiple awards for sustainability from Design Matters, MBAV, HIA, and the National Sustainability Awards for which he is now a judge. His company has worked to show that energy efficient sustainable design and Net Zero homes are a cost effective option and can be a mainstream reality. Jeremy is founding member of Builders Declare, and group dedicated to raising the standard of building practice, and currently sits on the Design Matters Board, the Sustainability TASC, and the NatHERS Stakeholder Consultative Group.
