From March 2027, England's new Future Homes and Buildings Standards will fundamentally change the way we design new homes. Among the most significant amendments is the introduction of a new functional requirement (L3), requiring on-site renewable electricity generation for new dwellings and residential buildings. At the same time, Part L of the Building Regulations shifts its emphasis beyond simply conserving energy to also reducing greenhouse gas emissions.
For architects, designers, planners and developers, the conversation has understandably centred around technologies such as solar photovoltaics, heat pumps and smart controls. Yet there is a danger that renewable systems become viewed as solutions in isolation. Technology performs best when it works with nature rather than against it—and that is precisely where Biophilic Design has an important role to play.
Biophilic Design is often associated with planting, biodiversity and occupant wellbeing, but at its core it is about understanding natural systems. Before selecting renewable technologies, we should first ask: how does this site already work? Where does the sun travel? How do prevailing winds move across the landscape? Which existing trees provide seasonal shade? How can natural daylight reduce the need for artificial lighting? These are biophilic questions, but they are also questions of building performance.
