REAL BUILDINGS, REAL PEOPLE, REAL DATA

More affordable to run & own, simpler to build, healthier to live in.

A portfolio of buildings with evidenced exceptional energy efficiency and carbon mitigation performances.

This unique collection of buildings are:

Fossil fuel free in operation
Naturally heated - with little to no reliance on primary central heating systems.
Naturally ventilated - avoiding the requirement for mechanical ventilation.

Each building is characterised by its optimised passive solar design techniques, high thermal mass structure, super-insulated fabric, low-tech operation and reduced materials specification.

The portfolio benefits from two decades of in-use building performance monitoring, peer reviewed publications and presentation at international conferences.

These buildings can also be described by what is not in them:

“No cavity walls, roof voids, no traditional foundations, no timber nor metal stud walls, no plasterboard, no heating boilers, no radiators nor the labyrinth of pipework, valves & thermostats, no ground source heat pumps, no air source heat pumps, the list goes on.”
