The guiding principles for new building are straight forward, energy and resource conservation in both construction and use.

In Northern Europe we have a preference for design principles that include a thermal buffer with mass, passive solar gain and
natural ventilation. But what techniques are appropriate for new building or the upgrading of an existing building often results in several being used.

We are familiar with and have designed many low energy buildings including:-

photovoltaic and solar thermal installations
heat store
rain water harvesting
ground/water source heating & cooling
low energy lighting and power
thermal mass tempering of air and heat recovery systems
combined heat and power

Examples projects that incorporating these are below:-

New house, Abbots Leigh, Bristol

Many energy saving features in a large high quality house - with solarium to trap solar gain & dynamic external blind protection

Refurbishment of a house in a conservation area, Bampton, Devon.

Existing house gutted & re-planned insulation clad, heat recovery, PV & thermal energy installations


A new sustainable house
Ludlow, Shropshire

Designed to exacting standards to ensure low energy use & using environmentally sustainable materials & Accoya - includes sliding solar/thermal screening of glazing.

New house, in conservation area

High thermal mass & envelope insulation, including adaptable
thermal buffer zone with
sliding roof shown open


fixing 80mm external insulation

The extensive upgrading of Grade II listed house in conservation area Bristol

The completed works take the conversion & performance of the house well beyond Building Regulation standards but have had little effect on the character of the house.

The Riverstation Restaurant

Diners are unaware of the comprehensive range of energy saving installations included in the building

TEEC plan layoutProposals for Tilbury Environment Energy Visitors Centre & Nature Park

The brief required 2 classrooms, a lecture theatre, exhibition space, messing & ablution facilities. The proposal is based on passive solar design principles with high thermal mass and use of sustainable building materials, all under a living roof. Fresh air for the building in summer & winter is tempered by passing through ground buried tubes.
The installed rain water harvesting, wind power/pump, ground source heat, solar water heating & PV installations provide one of the exhibition displays.
