Thermal labyrinth offers comfort at Canadian hospital
A new emergency department at a Canadian hospital enabled designers to use a basement void to install a thermal labyrinth and find their way to healthy energy savings. 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
Optimising HVAC system performance using BMS data analytics
Carbon Credentials uses advanced data analytics to drill down into BMS data and optimise the performance of HVAC systems. Founder Cian Duggan explains
Chain reaction – blockchain in construction
Blockchain could disrupt the construction sector. CIBSE’s Carl Collins explains how the technology can be used to bring the design and delivery teams together
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
Mission control – CIBSE Employer of the Year InTandem Systems
Industry relies on specialist controls firms to make complex buildings perform as intended. The exemplary work done by InTandem Systems to nurture engineers in the sector led to it being named CIBSE Employer of the Year. Alex Smith reports
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
National Gallery of Ireland’s hidden services
Refurbishment of the National Gallery of Ireland required tight environmental control in the galleries, but there was minimal space to make this happen, writes Chris Croly
District cooling at King’s Cross
A sliver of land between a rail line and offices was the only site available for a cooling centre at London’s King’s Cross. Metropolitan Infrastructure’s John Marsh, tells how it overcame space constraints to supply up to 12MW of cooling
