Letter from the Judges

Dear Students,

It is a great pleasure to announce the winners and the honourable mentions for the desert tent design competition.

Please see the attached report that says much of what we want to convey about our deliberations in arriving at the difficult decisions as to who to award the prizes to. the standards were very high.

We hope that above all this competition has made you think differently about design for an extremely hot climate and will be useful to you as designers in a heating world.

If there are any comments you might like to send to me about the competition and its impacts on you and your team do let me know and I can compile them and reflect on them.

The five winning teams will be put up on the competition website in the near future so you can go over them in detail. Fascinating stuff and we were really pleased with how many of you used Poala Sassi's Hot Box.

I hope also that you have learned some of the limitations of the modelling tools, and the importance of experimenting in the lab and in the field and with prototypes. Our plans to build a tent in the desert were ended with COVID, but i still have a dream to take a super tent to the Burning Man festival in Nevada one day and show them how it should be done! By the way one of you was right about this black blanket material - it works very well as I know from living under such a tent cloth when i lived with nomads in Iran on long migrations long ago.

Best wishes to each and every one of you for a safe, healthy, happy and successful future. Above all - thank you for entering this competition - we much appreciated each and every entry.

Sue and Joao

    Our climate is heating and weather records are being broken almost weekly. Yet, rather than reducing emissions, in 2018 global CO2 rose to a historic high of 33.1 Gt CO2 and temperatures are predicted to soar ever higher .

    We are in the midst of a climate emergency, species across the world are already becoming extinct. Yet, little appears to change in the construction industry with its business as usual regulations, building types and design tools.

    We now want to change the conversation for designers to help them create buildings that play a large role in climate solutions, rather than being part of the Global Heating problem and climate crisis.

    We hope this project will help change that conversation.


    The EXTREME LODGE project is sponsoring an international student competition to design a temporary shelter for climate researchers in the very hot desert climates of the Gulf.

    The competition will provide

    1. A New Design Process for developing and testing extreme structures;

    2. A deeper understanding of the Performance of Materials at high temperatures;

    3. A working knowledge of the Climatic Design drivers associated with form;

    4. Insight into Passive and Active Cooling opportunities at high temperatures;

    5. Experience in Laboratory, Bench and Field testing of structures and ideas;

    The Idea

    The idea for this competition came from building an extreme Polar Lodge for climate change researchers in Antarctica. This experience taught us the need to radically change how we think about designing structures at the extremes. Building models barely work for extreme conditions, empirical research does, providing informed solutions to design challenges that exist beyond the limits of our own understanding, and even imagination. The ‘Learning by Doing’ method works best, especially when done in conjunction with experts from industry who know how materials do and don’t work in reality at the extremes.

    The Extreme Design Process

    The Polar Lodge highlighted that simulation alone offers limited insights and opportunities for the design and construction of safe structures in extreme climates. It highlighted the usefulness of empirical learning and of bench and field testing in the development of the necessary understanding of the design challenges involved to produce safe and comfortable structures at the extremes. To enable extreme design to happen you may like to use our Extreme Design Process:

    Extreme Design Process

    1. Study the Site and its environs in great depth.

    2. Source, study and analyse appropriate vernacular archetypes for inspiration.

    3. Draft a variety of design principles and forms and test and compare to optimise.

    4. Explore and bench test innovative material solutions building with expert advice.

    5. Field or Laboratory test structures and materials in an appropriate test facility .

    6. Finalise structural and envelope design with tent makers.

    7. Transport and build final design on site (or Produce 2 x A1 sheets for submission).

    8. Continually monitor on site and refine structure for local conditions and users.

    So much of great design is derived from our experiences of the world and the way we interpret and apply the lessons from them. We hope that learning to apply a design process like this will help you to create better buildings.

    The only one we have!

    The Polar Lodge that we Built in 2019

    Design the desert lodge for dubai!


    Who is the tent for?

    Imagine the occupants of this tent. They are two researchers working on extreme desert species that occur in only one or two very hot sites. To study them they have to spend periods in the field to set up their experiments, monitor them and record the species in their natural habitat. They need an extreme tent to keep them thermally safe during the day and night in their field work, with ambient temperatures during the day of up to 45 o C. Above that all researchers are recalled from the field.

    Where is the tent?

    At the Dubai Desert Conservation Reserve (DDCR) researchers have been doing groundbreaking research since 1999 when 70 Arabian Oryx were introduced, and 6000 indigenous trees and shrubs were planted at its establishment. Today, many studies are undertaken using cameras and drones but one species which is being looked at in depth is that of small rodents in the very different habitats of sand dunes and gravel plains. The two researchers will have to spend up to two weeks at a time in the tent while they do in depth surveys of them in the field. Students should choose a site in any part of the reserve, and in all places the ground will be suitable for bashing guy pegs into to secure the tent.

    What is the climate like?

    Dubai has a hot desert climate with two distinct seasons, Summer and Winter. There is an excellent overview of the climate on Wikipedia. It shows that temperatures do towards 50 o C and, in a Heating World, records are being continually broken. As for the researchers, they will be recalled from field work when local temperatures rise over 45 o C so that is the maximum design temperatures for the competition. With the upper levels of acceptable temperatures for the adapted tent occupants being 35 o C (with a good breeze) then the tent cloth must be capable of reducing the Delta Temperature (ΔT) from out to in by at least 10 o C. Perhaps this is possible passively but there is also the option to use zero carbon active cooling, as long as it is achieved within the other rules of the competition.


    1 - Function and Comfort

    1.1. Sleeps two people;

    1.2. Floor area no more than 16m 2 but no other dimensions are fixed;

    1.3. People are able to walk about in it and also work in it at some times of the day;

    1.4. Use envelope materials that perform exceptionally well in high temperatures;

    1.5. Is capable of providing acceptable indoor conditions in ambient air temperatures of up to 45 o C in Dubai. During extreme heat events, researchers will be withdrawn from the field;

    1.6. Indoor temperatures from between 10 o to 35 o C are considered acceptable for acclimatized field researchers, so the tent will work fine if it can raise of lower temperatures to within this zone. See tab Hot Box to learn how you can measure this.

    2 - Environmental Impact

    2.1. Have net zero carbon emissions from passive and active systems for cooling. Solar works well;

    2.2 Low impact – leaving nothing behind to pollute the site once dismantled;

    2.3 The materials of the tent and its floor should be reusable, following circular economy thinking; CE normatives.

    3 - Transport and Erection Process

    3.1 Have a structure that is easy to erect and dismantle;

    3.2 Takes no more than four hours to assemble and fix in place;

    3.3 The tent must be capable of being carried in the back of a jeep;

    3.4 The tent must be capable of being assemble by two non-experts in tents, without special tools.

    Assessment Criteria

    This competition will not be judged on modelling (which is optional) or graphic design skills, but on the quality of the thinking and the empirical results that emerge from it.

    A huge amount of thought will need to given to not only the materials but also the way they fit together and into the ground (see figures below).

    Assessment Criteria
    • Materials and the Sun
    • Material Impacts
    • Energy
    • The Context
    • Tent Function
    • Overall Design Quality

    Hot Box Mini Lab

    Standardised Material Testing Procedure

    We developed a simple and very low cost method for all the participants to take measurements in a standardised manner. Please download the PDF file below with the standardised material testing procedure.

    We encourage all students to develop some ways of testing different materials to inform their choices of envelope design. Even a simple device like a cardboard Hot Box might be fun to use to experiment with individual materials and combinations of materials. See the attached Hot Box design but you can play with different configurations and sizes of test facilities. Make sure you include your thinking and testing regimes in the final two A1 sheets to help the judges understand why you made your design decisions. We hope the project will give you a good 'feel' for how materials perform and help you develop the habit of empirically exploring the world around you throughout your working life and the materials it is made of. We also attach a paper on how we experimented with materials for the Polar Lodge.
