Measuring indoor air quality in Passivhaus primary schools
Evidence from a study on indoor air quality in two Passivhaus primary schools reinforces the importance of well thought out ventilation and control of outdoor pollution
Lessons learned: UCL and Buro Happold’s award winning project review guidelines
University College London’s award-winning Post-Project Review guidelines – developed with Buro Happold – ensure lessons from projects on its estate are fed back into a process designed to improve building performance and close the performance gap. Phil Lattimore reports
Smart hot water tanks at the heart of the energy transition
Hot water tanks have the potential to store renewable energy, balance the electricity grid, and reduce carbon emissions and utility bills. Alex Smith speaks to Mixergy to find out how the hot water cylinder has the potential to become the smartest technology in the home
Handling Covid risk in thermal wheels
To minimise the risk of Covid-19 transmission in thermal wheels, designers should choose a configuration that minimises recirculation of contaminated air. FläktGroup’s David Black explains the options and how AHU purge sectors can cut the risk further
Platforms for growth: digital engineering for SMEs
Adopting a digital way of working may be daunting for SMEs with a fraction of the budget of big rivals, but Atkins’ Ben Roberts MCIBSE says in-house digital advocates, training and freely available tools can get firms up to speed quickly
Modelling the world’s tallest indoor waterfall at Jewel Changi Airport
Measuring the impact of thousands of gallons of water cascading through a deeply forested shopping centre was difficult enough for Atelier Ten’s modelling team, without having to consider trains passing through the building’s core. Andy Pearson finds out how they used cutting-edge models to meet the challenge at Singapore’s Jewel Changi Airport, and won a CIBSE Building Simulation Award in the process
Reality gap: Modelling with CIBSE TM63 to identify performance gaps
CIBSE’s TM63 helps identify a building’s performance gap by evaluating its in-use performance to provide a benchmark that reflects real-life operating conditions. Authors Esfand Burman and Nishesh Jain discuss the benefits of a calibration approach
