Thrilled to see Hampstead #Passivhaus shortlisted for the 2026 RIBA London Awards.

A Victorian conservation-area townhouse retrofitted to certified #EnerPHit:
• ~90% cut in space heating
• 75% lower operational energy
• 58% lower whole life carbon

Heritage + deep decarbonisation at its best.

EnerPHit on Heritage Projects: Balancing Performance and Conservation | Her Retrofit Space (CIC) posted on the topic | LinkedIn Heritage retrofit is where theory is truly tested. Working with older buildings means navigating moisture risk, fabric performance, heritage constraints and ambitious energy targets all at once. Achieving EnerPHit in this context is possible but it requires deep building physics understanding and confident decision making. We are delighted to be hosting a CPD session with Greengauge Building Energy Consultants focused on Achieving EnerPHit on Heritage Projects. This session will explore • How to deliver EnerPHit using both the space heating and component routes • Practical strategies for heritage buildings rather than idealised case studies • Why moisture risk analysis is critical when designing internal wall insulation • How to balance performance, durability and conservation in older homes EnerPHit is the highest certification for deep retrofit of existing buildings. It adapts the Passivhaus standard to make it achievable for older homes while still demanding exceptional performance in insulation, airtightness and energy efficiency. This session is essential for anyone working or wishing to work seriously in heritage retrofit. You will be learning from: Paul Smith, Director at Greengauge A highly experienced Building Physics Consultant, Passivhaus Certifier and Certified Passivhaus Consultant with nearly two decades of experience in low energy building design and delivery. Maria Valkova, Building Physicist at Greengauge Specialising in hygrothermal analysis, moisture risk assessment, thermal bridging and retrofit strategy development, with experience across PHPP, IES and SAP. Maria brings a rigorous and climate focused approach to intelligent retrofit design. This CPD is part of the ongoing programme inside Her Retrofit Space, the UK wide community supporting professional women working in retrofit. If you are an architect, designer, retrofit coordinator, assessor, engineer, tradeswomen, installer, consultant or currently training and want access to high quality CPD, trusted technical insight and a supportive professional network, join us today at www.herretrofitspace.com 👉 Join Her Retrofit Space to access this CPD and our full library of expert led sessions.

🙌 Really looking forward to speaking at this!
