International Building Services and Environmental Engineers

We are an international team of building services

engineers, environmental designers and lighting designers

focused on delivering sustainability in the built environment.

We have been designing “green” buildings for 20 years and

have evolved a team with the broad range of complementary

skills that are essential to the design of high performance

buildings of the future.

A pioneering approach

TermoDeck activated slab cooling system

The Kimberlin Library at Leicester University with

Eva Jiricna Architects (1996) was the first UK

application of the TermoDeck slab ventilation system

combined with adiabatic cooling for exceptionally low

heating and cooling demands. Integrating the air

supply with the concrete structure increases the

“thermal flywheel” effect.

A pioneering approachLabyrinths

Atelier Ten (re-)invented the idea of thermal

labyrinths for modern buildings with this gallery

conditioning system at the Earth Centre, UK (2000)

with Feilden Clegg Bradley Architects. The Labyrinth

eliminated the need for mechanical cooling. Power is

generated from the UK’s largetst PV array on a

timber structure made from forest thinnings.


Atelier Ten (re-)invented the idea of thermal

Centre, UK (2000) with Feilden Clegg

Bradley Architects. The Labyrinth eliminated

the need for mechanical cooling.


Intergenerational thinking for public builidngs-

the Labyrinth idea grew into a major installation

at Federation Square in Melbourne with LAB

Architecture Studio. Here again the labyrinth

eliminated the need for mechanical cooling to

the main circulation space and reduced

emissions by 90% compared to conventional

systems. (2002)

A pioneering approachLabyrinth Technology

Sustainability works at all scales and this

110m2 Alpine House at Kew Gardens in

London, designed with Wilkinson Eyre

Architects, relies on a subterranean labyrinth

to keep the plants in the cool and breezy

conditions that they need.

A pioneering approachGround Source Heating/CoolingTechnology

This Conference centre at Keble College in Oxford (Rick

Mather Architects) is heated and cooled by a ground

source heat pump connected through a network of

pipes to the piles that form the deep basement. The

piles act as heat exchangers. Though common in N

Europe, this was the first application of this technique in

the UK.

A pioneering approachEarth Duct Technology

Butterfield Office Village (2007) with Hamiltons

Architects was the first commercial building in the

UK to use Earth Ducts as the sole source of

comfort cooling for the summer and pre-heating in

the winter. Concrete tubes are buried below the

Car Park to couple with the earth around them.

The system is exceeding expectations and is

beginning to be widely copied.

A pioneering approachHigh Performance Buildings in the US

The Kroon Building at Yale University (2009) with Hopkins

Architects uses high performance indirect evaporative

cooling coupled with exposed thermal mass, a displacement

air supply and open loop GSHP to achieve very low carbon

conditioning, 70% below the notional ASHRAE 90.1 target.

The building achieved a LEED Platinum rating in 2009 and

has won 14 Awards.
