How much performance is enough?
When does “high-performance” building stop being efficient - and start becoming an exercise in chasing numbers?
Envirotecture Director Andy Marlow joins the Sustainable Builders Alliance podcast to talk Passivhaus, airtightness and the point of diminishing returns.
They explore questions including: How airtight is airtight enough? Where can smart design reduce cost without compromising performance? Why is condensation risk different? And are health, comfort and longevity ultimately more important than energy-efficiency targets themselves?
Andy also shares his thinking behind the relaunch of our sister-business, Passive House Design & Construct, and how the same principles of efficiency can be applied to the design process.
