The Kyoto House was developed by the property developer Promociones Montse Pujol, PMP, on a foundation of sustainable building criteria. The building, designed with the goal minimizing environmental impact, has been awarded the 2008 Endesa Prize for the most sustainable property development.
The â€śKyoto Houseâ€ť project has been awarded the 2008 Endesa Prize for the most sustainable property development. Montse Pujol Torrent, head of PMP, accepted the award for their achievement in this construction model â€śthat blends high sustainability and quality with the use of prefabricated systems,â€ť as well as PMPâ€™s â€śI follow Kyotoâ€ť campaign, for â€śits focus on clear and direct communication on the subject of sustainability.â€ť
The Kyoto House is a bioclimatic house prototype built using Pujol precast products and a design from the Pich-Aguilera Architecture Team, in collaboration with the president of the Lleida Technological Institute (Instituto TecnolĂłgico de LĂ©rida, ITL).
The current Kyoto House prototype has a floor area of 250 m2, spread over three floors; its cost is guaranteed when the project contract is signed, with a maximum delivery deadline of four months. Its versatile structure allows for the possibility of re-adaptation, and unlike the inflexible design of other projects, it allows customized layouts and materials and can incorporate more basic or more technologically sophisticated systems inside the house, with a corresponding influence on efficiency.
This prefabricated modular building solution allows for flexibility of spaces and changes in the dwellingâ€™s uses over time.
The building has been designed to have a minimal environmental impact. Its facades (openings and shapes) and interior layout have been designed to optimize the use of natural heat and lighting.
The Kyoto Houseâ€™s precast concrete components (columns, girders, facade panels, and flooring planks) enable quick and safe assembly.
The Kyoto House uses dry-fit construction components, which also means it can be disassembled. By manufacturing elements such as pillars, walls, and so on in the factory, and then assembling them on site, the design uses less concrete, energy, and water.
In addition to the precast components made by Pujol, the project also includes a covered cistern garden, a solar roof for electricity production, some solar pergolas for hot water, and two plenum walls that house the water and electrical services and in turn act as a chimney to draw fresh air from the basement and distribute it throughout the home.
One of the bioclimatic features of the Kyoto House is its cross-ventilation system. Fresh air entering through the basement is channelled through the plenum walls discussed above towards the top of the building. This creates a draft that allows for natural air conditioning. This system produces a temperature inside the house that is 5 to 10 degrees cooler than outside.
In addition, the concrete walls of the Kyoto House have a thermal mass that absorbs and retain the heat or cold inside of the house. This behaviour is similar to old-fashioned Catalan farmhouses.
The project also includes construction of a ventilated interior courtyard, an atrium that creates a specific microclimate that acts as a regulator between the inside and outside the home.
The roof of the Kyoto House, designed by the Pich Aguilera team, includes 24 photovoltaic solar panels that produce electricity. This power is sold back to the grid, which, in turn, delivers the energy needed for the house.
Two thermal solar panels, consisting of tubes capable of capturing solar energy, cover the inner courtyard of the house and also create an overhang over one of the facades. These panels, which operate as sun shades, are capable of capturing solar energy for hot water and as supplemental heat for the central heating system.
A terrace garden cistern collects rainwater from the roof and stores it for use in irrigation. The grass planted over this terrace cistern is the first beneficiary of the water that it collects, and it also operates as an insulating layer for the building.
The project also includes graywater recycling (water from showers, toilets, and washing machines); this water, once treated, can be used for flushing of toilets and irrigation.
