The Passivhaus Trust is an independent, non-profit organisation that provides leadership in the UK for the adoption of the Passivhaus standard and methodology.

The Trust aims to promote Passivhaus as a highly effective way of providing high standards of occupant comfort and health as well as reducing energy use and carbon emissions from buildings in the UK.

Passivhaus is a proven solution to slash energy use, backed by three decades of performance evidence from across the globe. Efficiency is crucial to meet net-zero carbon targets.  The Icebox Challenge has travelled the globe, and this year comes to Glasgow in the run-up to COP26. Student design competitions like this offer valuable opportunities for our next generation of architects & designers to get inspired by the climate action they can engage in. We anticipate the public installation will capture people’s attention, facilitate vital discussions, and raise awareness of the impact of simple solutions such as Passivhaus.

Global Alliance for Buildings and Construction

The Global Alliance for Buildings and Construction (GlobalABC) works towards a zero-emission, efficient, and resilient buildings and construction sector through:

  • Raising ambitions to meet the Paris climate goals. While the sector is a major emitter, it also holds huge potential for improvement. We work to raise the level of ambition in retrofitting existing buildings and future-proofing the investments that we will see going into new buildings over the next 15 years.
  • Mobilizing all actors along the value chain. Faced with a fragmented value chain, all stakeholders – from design to construction, operations and demolition in the private and public sectors – need to play their part. We encourage policy frameworks that promote both uptake of existing, cost-effective solutions and private sector innovation – using sustainable public procurement as a lever to create markets and investor security.


Construction Scotland Innovation Centre (CSIC)

By linking together businesses, university experts, the public sector and the economic development networks, CSIC's industry-led team supports a culture of innovation that drives transformational change across the construction industry.

Shettleston Housing Association

Shettleston Housing Association is a community based housing association, a Registered Social landlord and a Scottish Charity. It was formed in 1976 by local people who were concerned at the deterioration of their community and who wanted to save the traditional sandstone tenements that embodied that community. The Association operates within the Shettleston, Greenfield, Springboig and Sandyhills areas of the east end of the city of Glasgow serving a population of around 15,000. It has 2398 homes in ownership - mainly for social rent. It also provides a factoring service to local owners.

Shettleston Housing Association has a strong legacy of building sustainably and with innovation, including its ground-breaking, highly energy efficient Amulree Street development constructed in 1998. This car-free project pioneered many sustainable features including high insulation levels; solar and geothermal energy systems; use of recycled materials; solar and passive ventilation; and materials chosen to lower preservatives and formaldehyde levels.

This commitment to energy efficiency and securing the best outcomes for tenants has continued with recent development projects, including Glasgow's first Passivhaus social housing project at Carntyne Church completed in the summer of 2019. This development combined the sensitive conversion of Carntyne Old Parish Church into bespoke, energy efficient flats and the construction of a block of 5 new homes constructed to Passivhaus standard. All flats are let to older tenants. These homes have extremely high levels of thermal insulation, triple glazing and mechanical ventilation and heat recovery systems and residents benefit from improved levels of comfort, air quality and reduced heating costs.

The Association's focus on continued improvements to the energy efficiency of existing properties and the construction of new, sustainable housing is driven by the desire to bring real and lasting benefit to tenants by lowering fuel costs and enhancing the comfort of their homes.

Donna Williams, Sanctuary Director – Sustainability and Climate Change, said: “We’re proudly sponsoring the Ice Box Challenge because the innovation behind it is of great importance for shaping the future of affordable and sustainable housing design.”

Centre for Offsite Construction + Innovative Structures

Timber TED Pathway

The Timber Technology, Engineering and Design Pathway follows an evidence-based approach to creating learning experiences based upon a competency framework that answers the question “What knowledge and meta skills does the next generation of timber engineers need to have to drive change in the construction industry?”

This framework is based on industry’s needs and sets the foundation for creating engaging challenge-based learning experiences. The IceBox Challenge is only one of these engaging challenges with more to come in the upcoming months. Each learner will be able to navigate their own engaging learning experience by progressing through the pathway via different junctions.  Along their journey they will be supported by an on-demand knowledge library, a collation of reliable and practical resources provided kindly by our partners, where learners can find the information they need at the time they need it in bite-sized amounts.

The Timber TED project is based at Edinburgh Napier University and is funded by the Housing Construction and Infrastructure Skills Gateway and the Ufi VocTech Trust. Our steering group members are TRADA, Construction Scotland Innovation Centre, Structural Timber Association, Trussed Rafter Association and Swedish Wood.”
