The iCon is a new type of publically funded building, which actively
promotes economic sustainability for local boroughs via the promotion
of an Innovations Network or ‘iNet’. There are 4 iNets in the East
Midlands. The iCon building forms the Sustainable Construction iNet.
The 4000m2 iCon building is a BREEAM Excellent exemplar project
which uses less than 15 Kg of CO2/m2/yr and showcases the feasibility
of achieving maximum energy efficiency and zero carbon status via
sustainable design and construction techniques and integration of
renewable energy technologies.
The innovation hub and office building in Daventry includes 54
incubation units for start up businesses, public exhibition space,
conferencing facilities and cafe.
It utilises features such as a timber frame construction, passive
ventilation systems, efficient heat recovery and the first commercial
application of DuPont™ Energain phase-change materials to limit
overheating. These phase change materials have been introduced
into a number of rooms, at soffit level, and can help to reduce interior
temperature peaks by as much as 7°C, optimising comfort levels and
helping to save energy. This decreases air conditioning costs (by an
average of 35%) and heating costs (about 15%) and can therefore
make a meaningful contribution to reducing the carbon footprint of a
building.
The system is supplied in panels which are sealed behind the
plasterboard in walls or above ceiling panels where it absorbs ambient
heat as room temperature rises (at around 22°), storing it until the
temperature drops again (at around 18°), and then releasing it back
into the room. It is the intent to measure the effectiveness of this
material by comparing temperature changes against similar rooms
that have not had the material installed.
