Post-occupancy evaluation of hybrid ventilation in schools

Temperature and air quality in classrooms are known to affect learning, but new schools are often built on tight budgets and with low carbon ambitions. Post-occupancy evaluation is adding to the evidence for local hybrid ventilation systems, says BAM Construct UK’s Paula Morgenstern

Technical due diligence in commercial property

Robust technical advice given by an M&E engineer can benefit property landlords, investors and occupants – so, asks Tuffin Ferraby Taylor’s Marc Hill, why do so few consultants offer expert transactional services?

Using CFD to predict flows in chilled beams

Computational Fluid Dynamics can be used to gauge flow predictions for chilled beams, according to Abdullah Karimi’s paper presented at the ASHRAE 2018 Winter Conference. Tim Dwyer reports

Biomass boilerhouse blues – and how to avoid them

Integrating biomass boilers with fossil-fuelled ones creates issues for systems design. In his second article, David Palmer outlines the mathematical modelling needed to inform design decisions

Intelligent load control using circuit breakers

A power-management function built into a circuit breaker can help building operators avoid penalty charges for exceeding the peak consumption agreed in energy contracts, says ABB’s Atif Saleri

Understanding why biomass boilers fail

Successful design of biomass boilers requires a systems approach, says David Palmer, who considers how factors such as oversizing, lack of thermal stores and poor flue-system design can cause boilers to underperform
