Simplifying building services installation

Using a single pipework installation method across an entire project has a number of benefits. Scott James, director at Viega, explains how press connection systems can provide the solution and the benefits of a single source of supply for copper, steel, stainless steel and multi-layer pipework

The impact on system design

As older systems come to the end of their life, they are progressively being replaced with alternatives that use lower GWP refrigerants. Martin Passingham, product manager for DX at Daikin UK, looks at what this means for the design of existing systems

Materials for potable water

Careful specification of the materials for drinking water applications will ensure the quality of the supply within a building is maintained. Here, Scott James, Director at Viega discusses the factors that engineers and installers need to consider

Recovery, recycling and reuse

Significantly reducing the demand for imported higher-GWP refrigerants before the next quota reduction in 2021 will be key to avoiding many supply and price issues experienced since late 2017, says Daikin’s Martin Passingham
