The International Sustainable Energy Conference (ISEC) 2024 is a pivotal event that addresses the pressing challenges of renewable heating and cooling in integrated urban and industrial energy systems. Set against the backdrop of the Messecongress Graz in Austria on 10 – 11 April 2024, this conference is the third of its kind, following the successes of its predecessors in 2018 and 2022.

ISEC 2024 embarks on an ambitious journey to explore how energy sovereignty can be achieved within the urgent timelines dictated by climate change and political landscapes. The event will spotlight global solutions like the transition towards a sustainable circular economy, the cessation of fossil fuel usage, sector coupling, energy storage systems, and the smart electrification of energy supplies.

A distinctive feature of ISEC 2024 is its inclusive approach, fostering a rich exchange between research, industry, and energy policy. The conference will feature a blend of invited speakers from varied domains alongside global presentations and poster sessions by researchers, aiming to spark innovative ideas for heat transformation and resource efficiency in renewable energy systems.

Howgate Close – scientific paper to be delivered at the conference

The Howgate Close project in Nottingham is a pioneering new-build initiative that creates sustainable, low-rise residential housing. Designed by Dr. Jerry Harrall with the EWI Pro EPS system, the project boasts remarkable energy efficiency with a U-value of 0.08 W/m²K and an air pressure test result of 0.45 m³/(h·m²) at 50 Pascals. Inspired by the Hockerton Housing Project, Howgate Close incorporates passive solar design, high thermal mass, super insulation, and renewable energy to create a self-sufficient community. This development addresses the shortage of affordable rural homes and enhances biodiversity through extensive planting and the creation of natural habitats. Howgate Close is classed as a post-hydrocarbon-ready set of homes.

What is a post-hydrocarbon-ready home?

A post-hydrocarbon-ready home is designed to operate efficiently without reliance on fossil fuels, incorporating renewable energy sources and sustainable building materials. These homes are built with future energy needs in mind, aiming for minimal environmental impact and reduced energy costs. They often feature advanced insulation, energy-efficient appliances, and systems for generating renewable energy, such as solar panels, to ensure resilience against changing energy landscapes and to promote sustainability.
