EnerPHit Component Step-by-Step

Theoretical case-study retrofits

Passivhaus retrofit doesn’t have to mean heroic single intervention projects and all-or-nothing targets. In this research paper, a staged EnerPHit component method approach is modelled across four common UK dwelling archetypes, to examine how it incrementally delivers on space heating savings, lower energy bills and reduced carbon emissions.

The paper explores such questions as:

• What’s the energy and emissions impact if your first retrofit step is also a loft conversion?
• How do the calculations change if you install a heat pump earlier?
• Can direct electric be an affordable heating option for flats?

Plus, it offers PHPP tips for retrofit step-by-step modelling in the UK. Essential reading for designers and consultants, architects, policy makers, and clients.
