A higher authority – upgrading valves at Chiswick Park

Pressure independent control valves can offer extensive energy benefits according to manufactures. Frese has fitted 1,060 units to an office building at Chiswick Park, so Tim Dwyer spoke to managing director Stephen Hart to find out more

Build tight – ventilate right?

Indoor air quality in housing is being compromised because ventilation scenarios in Building Regulations are not realistic, says Strathclyde University’s Stirling Howieson, who co-wrote the paper that won the 2015 Napier Shaw Bronze Medal

Prepare for landing

As the 2016 deadline for using BIM Level 2 on public sector projects looms, Martin Howe explains how Shepherd Engineering Services is adapting to BIM by improving supply chain coordination and integrating its software tools

Back to basics

With some way to go before natural ventilation is completely accepted as a viable alternative to mechanical systems, Andrew Acred shares a simple model for implementing it effectively in atria buildings

Light at the end of the tunnel

Endless corridors, dingy waiting rooms and basement treatment rooms will be a thing of the past at Guy’s new Cancer Centre when it opens in 2016. Liza Young finds out how innovative service design has helped to create a blueprint for modern cancer care buildings

On a mission

Portakabin is using CIBSE’s TM54 tool to help predict energy use at a new Cambridge base for the East Anglian Air Ambulance. Peter Rankin explains why the modular builder is taking an ‘honest approach’ to energy efficiency

The power of three

New CIBSE President Nick Mead joins fellow presidents Andy Sneyd and Stephen Hodder to discuss how institutions can encourage the professions to break out of their silos and become involved in collaboration. Ewen Rose senses a cultural change at the first presidential debate in Westminster Central Hall

Exposing the underground

The mass of underground services buried beneath our streets is a major hurdle to creating smart, resilient cities, say Nicole Metje and Dexter Hunt, who consider sustainable methods of managing 4 million km of buried infrastructure in the UK

Street smart

Local electrical power networks have the potential to slash household energy bills by half, but are being held in check by regulations on domestic energy management. A pilot project in Wiltshire is showing how modern controls, clever algorithms and more enlightened legislation could transform UK energy supply. Encraft’s Matthew Rhodes and Paula Quintela, of e2E Services, explain

For those about to dock

The installation of PV panels means more UK homes are moving from AC to DC generation. This makes electrical distribution more efficient, says Ian Billington, since most electricity demand in households – such as LEDs, digital devices and, in future, electric cars – are DC loads
