DESIGN OF BIOCLIMATIC HOUSES IN TENERIFE

AIMS AND COMPETITION PROGRAMME

The Municipal authorities of the Island of Tenerife (Spain), in collaboration with the Tenerife Technological Institute for Renewable Energy Sources, launched an open international competition for the design of one-family bioclimatic houses in the Granadilla technological park and entrusted the College of Architects of the Canary Islands with its organisation. The competition, conform with the UNESCO/UIA Recommendation, received the approval of the International Union of Architects - UIA
The aim of this competition was to select, with a view to construction, 25 one-family houses, designed according to bioclimatic principles, using renewable energy sources and, wherever possible, recycled and recyclable construction materials, on a site on the edge of the Atlantic ocean particularly suitable for the use of solar and aeolian energy. Water treatment and recycling of waste were also to be taken into consideration, so as to make of this technological park of Granadilla a pilot ecological complex, destined to receive experimental, technical and scientific tourism.

JURY AND ADJUDICATION

212 projects were submitted to the international jury made up of Ricardo Melchior Navarro, President of the jury, (Vice-President of the Cabildo Insular de Tenerife), Francisco Javier Gonzalez Reyes, Dean of the College of Architects of the Canary Islands, Jaime Lopez de Asiain, Rector of the School of Architecture of Seville (Spain), Gregory Franta, architect (USA), Sanjay Prakash, architect (India), Ruth Lahav, architect (Israel), representing the UIA, Georges Wursteisen, architect (France). Rafael Serra Florensa, Rector of the School of Architecture of Barcelona and Janos Szasz, architect (Hungary) took part as deputy members.

The jury met at the headquarters of the College of Architects of the Canaries, from 25 to 27 October 1995. After examining the reports drawn up by the technical commission, the jury proceeded to make a first selection based on the following criteria:

• The appropriateness of the architectural design to the programme requirements;
• The project's illustration of specific research into bioclimatic architecture;
• Outstanding architectural expression, justifying the project's place in an exhibition.

The jury selected 57 projects which it re-examined in relation to the following criteria:

• Construction feasibility;
• Technological and architectural innovation;
• The capacity of the project to generate topological diversity.

The jury retained 35 proposals, from which it selected the 25 finalists, to be built in the Grandilla park. The promoter of the competition reserves the right to choose from amongst the ten other projects that or those to be built in the event of one or several of the winning teams deciding against the realisation of its project.

Finally, the jury decided to award three first prizes from amongst the 25 winning projects, based on the following criteria:

• The judicious use of passive systems or technologies and their architectural application;
• The incorporation of recyclable or vernacular materials, traditional technologies and lifestyle of the region in the design;
• Concern for innovation expressed through the architectural proposal.

After this selection, anonymity was lifted to reveal the following prize winners:

JURY'S COMMENTS

According to the members of the jury, &laqno; the competition reflects the interest of architects from different countries for the thematic and aims of the programme proposed. The positive results obtained through this competition are the outcome of a fruitful and exemplary collaboration between the local authorities and the profession. »
&laqno; The competition was also an exceptional opportunity to redefine the principles of bioclimatic architecture, notably:

• Integration in the natural environment, relief and climate;
• The quality of the relationship between exterior and interior spaces;
• The ability of the houses to generate a coherent urban whole;
• The evaluation of the construction and maintenance costs;
• The appropriateness and feasibility of the design in relation to economy of energy;
• Consideration of local technologies and materials as well as lifestyle of the inhabitants of the region where the project is situated.».
