A project to develop design techniques and elements of building construction for incorporation into low-energy office and public buildings designed by Michael Hopkins and Partners

Cel

The Objective of the project is to develop the design of a number of building components that will be used in low energy buildings designed by Michael Hopkins & Partners, mainly in the UK.

A massive reduction in energy demands is possible if the building materials and ventilation system are adapted as they have been in the prototype testing; a decrease from 360 to 67 kWh/m2 per year has been shown. (Note that this assumes that the building is using other energy saving options as well as the new design features.) The computer simulations were shown to represent the actual conditions quite effectively and will form useful design tools in the future.

Overall the tests indicated that all principle design components perform effectively: the ventilated floor slabs can be used to efficiently store heat, the ventilation system provides pleasant working conditions and the exterior wall reduces solar gains. Up to 60% of the solar gains can be recovered using dark blinds in the glazing and light shelves reduce artificial light requirements by 55%.
Research will focus on the thermal performance of a triple-glazed ventilated external wall, in conjunction with the use of floor slabs and internal walls as a thermal store, a floor-supplied displacement ventilation system and light shelves to reflect daylight into the building's interior. The research will involve developing computer models of the thermal behaviour of these elements, testing on full prototypes and refining the design of individual components.

The behaviour of elements will be analysed both individually and in interaction with other elements to enable the results to be used in different permutations on live projects. The ventilated wall will be tested in a PASSYS test cell to validate the computer simulation. A full-size prototype of the wall will then be installed in the external wall of the test centre building to monitor the wall's design and thermal performance over a period of time.
The deliverables will comprise: predictions of the thermal performance of individual elements of building construction; predictions of the thermal performance of a typical room; predictions of natural lighting levels under different weather conditions; forecasts of annual energy demand.
Algorithms will be developed to model the performance of components, using computational fluid dynamics and thermal models.
