Home energy simulation could revolutionise low carbon heating design – Report

The new Home Energy Dynamics (HED) tool developed by Energy Systems Catapult can help design low carbon heating and retrofit solutions to optimise the cost of upgrading the UK’s 27 million homes to meet climate targets, according to a study. 

The HED simulation tool can take data from heating systems, radiators and pipe networks, building fabric, combined with consumer behaviour and weather data, to develop efficient low carbon heating upgrade pathways. The study uses HED to map low carbon heating upgrade pathways for five common UK housing types, with changes including: improved heating control, building fabric upgrades, heat pumps (with or without existing gas boilers) and thermal storage. This approach could provide landlords, housing associations, heating engineers, energy service providers and others with a clear, evidence-based way to plan future property improvements and prioritise upgrades which deliver cost effective energy efficiency and comfort. The study complements the Committee on Climate Change ‘Net-Zero’ report that advised that improvements to building efficiency and adoption of low carbon heating systems, such as heat pumps, district heating and hydrogen boilers, were required for the UK to reduce carbon emissions to zero by 2050. With two-thirds of UK homes currently suffering from damp, draughts or overheating, the study found improved heating control combined with modest energy efficiency retrofit could ensure the switch to low carbon heating also delivers improved outcomes for householders.
