1- Place and concept

The Scouts Eco-Camp is located at the parish of Aldreu, municipality of Barcelos, in a mountainous area near the Atlantic sea. The Eco-Camp occupies the two sides of the hill, one facing North-West and the other facing South-West.

The site was occupied in the final period of the Neolithic, remaining a few ruins of this human settlement. The fact that there is a natural spring water on the site and a view of the lower lands located by the sea, explains this first human occupation.

At present, the place is considered as a natural landscape, requiring, therefore, a very special care in the planning of the Eco-Camp.

The soil is granitic with a layer of vegetal soil that allows the subsistence of large tree species. The site, which was the place of several forest fires, being the last one on the summer of 2016, is in planning of reforestation with autochthonous species, namely the oak.

The prevailing fauna is characterized by birds of prey and terrestrial species such as partridges and rabbits.

Solar exposure, wind exposure and the existence of a natural spring water make it possible to intervene in this place in a sustainable perspective, creating a facility with near zero environmental impact, being able to be self sufficient in the production of electricity, water supply and natural treatment of waste water.

The construction of shelters/bird watching units must be architectural objects with a low environmental impact, while at the same time being elements that identify the Scouts Eco-Camp in the natural landscape. Its reversibility, modularity and the use of lightweight materials with low environmental impact are some of the main characteristics to be taken into account when developing solutions for the shelters.

2- Shelters location

Shelters will be located on two granitic spots as the following:

- SHELTER 1 at the North side of the eco-camp (see figure 3);
- SHELTER 2 at the South side of the Eco-Camp (see figure 3).

3- Architectural characterization of the shelters

The shelters proposals must consider the following aspects:

- 25 years lifespan;
- Maximum interior area of 30 m2;
- Open space;
- Must be possible to be demountable at any time;
- Must provide views to the surrounding landscape;
- Must provide thermal comfort to the occupants.

4- Sustainability goals

4.1- Shelters must achieve the following sustainability goals for a 25 years lifespan:

- Be demountable and their materials and components possible to be reused or recycled;
- Provide natural ventilation;
- Provide natural light and shade;
- Reduced and easy maintenance;
- Include reused or recycled materials (not mandatory).

4.2- Shelters must minimise the following indicators on a life cycle perspective (materials supply, construction, operation, maintenance and deconstruction):

- Embodied mass (kg);
- Embodied energy (MJ);
- Global Warming Potential (GWP) (kg C02e).

4.3- Shelters must maximise the following indicators on a life cycle perspective (materials supply, construction, operation, maintenance and deconstruction):

- Amount of reusable/recyclable mass content (%);
- Amount of reused/recycled mass content (%) (not mandatory).

5- System of Units

5.1- Proposals must follow the International System of Units (SI), namely the following:

- Unit of length (meter);
- Unit of mass (kilogram);
- Unit of temperature (kelvin);
- Unit of luminous intensity (candela).

6- Proposal contents

Posters must contain the following information:

- Text explaining the concept of the solution;
- Text describing the technical proposal;
- Text explaining the sustainable goals achieved;
- Tables and graphs (not mandatory);
- General plans, façades and sections drawn at the following scale: 1/50;
- Construction detailed sections drawn at the following scale: 1/20;
- Other selected construction details drawn at the following scales: 1/2 or 1/1 (not mandatory);
- Detailed draws must mention construction materials;
- 3D views.

7- Presentation of proposals

7.1- The proposal includes:

- 3 posters describing the solution.

7.2- About posters:

- Posters must be presented according to the provided poster layout;
- The layout includes mandatory fields that must be edited by the authors, where colours, letter fonts and sizes are not allowed to be changed;
- The layout will include a free space to include texts, drawings, images, figures and tables that better explain the proposal and where authors may use graphic and colour schemes at their choice.
- Posters must be high quality printed in a 150 g/m2 uncoated paper (or similar).

7.3- Sending the proposals:

-.Team form and students’ documentation must be inserted in a closed envelope with the TEAM CODE written outside.
- The envelope and posters must be rolled and sent to the postal address of the competition.
- Team Form, documentation and posters must also be sent as separated high quality pdf files to the competition email.

7.4- Each proposal must include valid documentation stating that the Team elements are students, mentioning their University and Course. These documents must be inserted in a closed envelope with the TEAM CODE written outside.

7.5- Confirmation of delivery will be sent to each Team.

7.6- Incomplete proposals will be asked to be completed on a 15 days deadline after the Competition Secretariat request.
