Higher standards of insulation and control of air leakage in buildings is called for in the forthcoming revised UK Building Regulations. In particular, Part L of the Building Regulations has been reviewed with a brief to make new buildings more energy efficient and to tackle climate change. The revised changes will be enforced from April 2006.
This will mean new buildings will need to be better insulated and use more efficient heating systems. And importantly, for the first time the revised Part L1 (for dwellings) will make air pressure leakage testing mandatory. Poor levels of air tightness in buildings can contribute significantly to heat loss since warm air will be replaced by cold air due to thermal air currents, or in simple terms drafts!

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
