Researching new methods for estimating design water flowrate

It is recognised that using the traditional loading units method overestimates the design flow for hot and cold water systems. Heriot-Watt University’s Achala Wickramasinghe explains how the Luna project aims to address the issue and calls for data to help validate a new method

To close the performance gap, choose Option D

IPMVP Option D offers robust measurement and verification to give building services engineers and their clients a better insight into how a design energy performance rating can be validated during operation. Nazli Dabidian explains how

Countdown to zero – Leti roadmap to zero carbon buildings by 2030

The London Energy Transformation Initiative aims to support the construction of zero carbon buildings by 2030. It is creating a roadmap describing how this can be achieved, and newly crowned CIBSE Building Performance Engineer of the Year Clara Bagenal George says anyone in the industry can get involved

Cost model – battery storage

Advances in battery technology and steep falls in prices for PVs and storage is making smart energy grids an attractive commercial proposition. Aecom’s first cost model of the year assesses the viability of batteries across a number of scenarios

Data with destiny – BMS protocols

Building data offers valuable insights into performance, so it is essential protocols are in place to ensure digital information imported from the building management system is robust and relevant, says BuroHappold Engineering’s Tom Hopton FCIBSE
