The Energyflo™ Cell
• Multi-functional product that
replaces conventional wall
insulation in buildings.
• Transforms the wall into a
heat exchanger, fresh air
ventilation source and filter of
airborne pollution.
600 mm square and 95 mm thick [140 mm with air cavities]
• Transforms the building into a
sustainable, clean, energy
efficient DBB.

In order to achieve comparable performance, a traditional house
build would require 250 mm thick polyurethane foam insulation
over the whole of the available roof, wall and floor areas.

CALA Hazeldean House
• The carbon footprint is 50% LOWER than Building Regulation requirements
and energy costs that are 1/3rd of the UK average dwelling.
• This has been achieved against a whole-house fresh air ventilation rate of ~0.7
ach, to deliver a significant boost in Indoor Air Quality (IAQ).

• The DBB approach delivers substantial cuts in air conditioning plant cost and
energy use without compromising the IAQ or comfort level of internal spaces.
• It also allows planned economic expansion by reducing the scale of future
electricity infrastructure investment.

Conclusions
•
The CALA Hazledean project has demonstrated the viability of the Dynamic
Breathing Building (DBB) approach and of the Energyflo™ cell .
•
It has also revealed important synergetic and interactive features that are
unique to roof installations, extending scientific knowledge.
•
A sound basis for exploring and developing new DBB systems and new
variants of the Energyflo™ cell, for example to use in cavity wall
construction, has been established.
•
The case studies shown demonstrate the potential of the Energyflo™ cell as
a versatile product that can be used anywhere in the world.
•
This clean technology can be used to enhance all building types, from
schools and hospitals to commercial, industrial and municipal buildings.
