Electricity metering with remote reading for for every building in the MOD estates: Tidworth, Larkhill and Bulford.

HMS Sultan, accommodation blocks, boiler plant replaced to reduce fuel consumption.

West Dean Visitors Centre
West Dean Visitors Centre

The visitors centre was conceived by Prof Christopher Alexander, CES California, as a sustainable building using locally sourced materials and traditional building methods. The building houses a restaurant, ticket sales, toilets and a shop. Heating is provided by the site central boiler house adjacent, the boilers are fueled by wood chips produced on the estate from forestry waste, heating is embedded in the floors and walls.

Case study

The Holland 1 submarine is the first submarine, one of several of the same type, built for the Royal Navy. From 1902 it operated as part of the embryonic submarine flotilla which led to the development of the RN submarine navy. The boat was intended to be scrapped but foundered and sank off the Eddystone light in 1913 when it was being taken to the breakers yard. After lying on the sea bed for 70 years it was rediscovered, brought to the surface in 1982 and eventually put on display in the open air at the RN Submarine museum. The many years on the sea bed eventually began to tell and it became clear that salt had entered the metal causing it to rust rapidly. In 1995 a conservation process was started which culminated in the construction of the new building to provide a controlled environment.

Whilst most of the salt has been soaked away the conservation of the submarine now requires very low humidity conditions to prevent corrosion caused by the salt remaining. The building is sealed and provided with airlocks to prevent moisture entering from outside with visitors and the air is dehumidified, the dehumidifier produces heat in the air which requires cooling. The building incorporates high value insulation and high mass construction, the mass of the submarine is also used to absorb heat and the building temperature is allowed to rise through the day and the temperature and humidity are reduced overnight the most efficient time of day for cooling. A heat pump is used for cooling and heating. The project was initially intended to include a heat source/sink with water taken from Portsmouth harbor, but this could not be afforded by the project.
