Owner approach of sustainability : The aim of the design was to build a self-sufficient home, using renewable energy and sustainable materials 

he design objectives were:
* Avoid falling into sustainability doctrines or fashions that could involve extra costs.
* Selection of natural and low environmental impact materials on equal quality-price ratio.
* Achieve maximum durability with minimal maintenance.
* Reduce environmental impact and building time.

Architectural description: The building is a self-promoting two storey detached house, one is a semi-basement. The most remarkable fact about the building is that the structural system is a set of used ship containers. The building energy performance has been carefully designed to achieve an A rating and reduce the CO2 emissions and operating costs.
A rectangular plan shape has been used to achieve minimum heat losses. All the non-living areas have been designed to be on the semi-basement. On the upper level the layout respond to one bedroom apartments. A future roof extension has also been previewed.

The design process has involved an extensive data collection and research on container construction, usage, processing and transport. It has also led to an investigation on compatibility between the containers structural support and enclosure.

Some energy aspects of the project are:
Alternative energy use: aerothermal heat pump for heat, DHW and passive cold.
Mechanical ventilation heat recovery.
Natural light and ventilation in all rooms.
Efficient lighting, energy saving lamps with PIR sensor.
High performance thermal insulation with vapor and air tightness barrier.

Owner approach of sustainability

By participating on the competition we are seeking to spread our projects made by recycled sea containers. The idea and design about these projects is based on the 4R´s: Reduce Reuse Recycle Research We have thought of materials from nature, with a transformation and recycling low cost, without falling into radical approaches involving inefficiencies or unbearable overcosts. In our passive houses designs, we have balanced the energy consumption in relation with an standard reference building, the square meters cost and the GEI emissions at the usage stage. These data have been checked carefully and they have helped us to get the most ecoefficient case study at Construction21 Spain on 2014.

Architectural description

The house is a compact building with a straightforward geometry. It is result of joining three reused sea containers next to each other above a podium 1m high above ground. Below this there a semi-basement space. The reused sea containers are the main structure of the house. They load over the semi-basement concrete walls and allow a quick, low budget and efficient mean of construction. The building energy performance has been carefully designed to achieve an A rating and reduce the CO2 emissions and operating costs. The semi-basement storey is directly above the compacted earth and hosts all the non-living spaces, this allow an easy way of creating a thick and continuous insulation line below the living spaces above. The slab and floor is the container structure. The house layout has been designed to match the client requirements, looking for the best orientation for each living space in order to get the optimum comfort conditions.

Envelope performance

  • 0,18 W.m-2.K-1
  • Envelope U-Value: 0,27 W.m-2.K-1
    More information : The envelope has been carefully designed to reduce thermal bridges and insulate the building to make it energy-efficient. One of the advantages of using used containers is that the containers are virtually airtight, preventing air infiltration. The thermal envelop is almost continuous. Overheating risk has been avoided at South facade by the design of fixed and movable sun shades. These shades are lined out the window skirt, projecting above the finish of the facade and shadowing the window and facade. In the same way the reused container doors have been designed to allow a winter protection (they can be completely closed, insulating the windows) and also as a shadow element (allowing to be fixed according to the sun position).

    Description
    ELFOPack is an "all in one" air-source heat pump unit, which covers the needs of heating, cooling, hot water, mechanical ventilation with thermodynamic heat recovery and electronic filtration. The main features of ELFOPack are:
    Ambient comfort through a compact full fresh, outdoor air unit, which uses heat pump technology to supply air into the house at the ideal temperature and at the right humidity condition. Thanks to its low thermal inertia, the system allows to quickly meet the required heat load.
    Domestic hot water production, simultaneously to heating and cooling, with very low energy consumption in winter, and free in summer. 
    Continuous air purification, using electronic filters, with efficiency higher than 99.9 %, and extracting exhausted air from areas where humidity and foul odours predominate.
    High efficiency thanks to the active recovery of the energy contained in the exhaust air, to the free-cooling and free-heating, where adequate ambient conditions are present, and to the exploitation of renewable energy.
    Decentralized solution which guarantees the end user a reduction in charges by eliminating all the waste of energy of a traditional centralised system, such as distribution losses and pipeline pumping power, thereby achieving reliable utility metering without using a thermal energy monitoring system (EMS).

Urban environment

URBAN ENVIRONMENT The environment is a urban sprawl of detached houses built on a plain and well sunlited surface, that´s the reason why sunlight shades are so important on this project. There was only one tree on site that´s has been preserved although it was an obstacle for access. Aparcamiento : The car park has been designe don th semi-basment that allows natual sunlight and ventilation. this allow an easy way of creating a thick and continuous insulation line below the living spaces above. The slab and floor is the container structure.

Building Environmental Quality

  • indoor air quality and health
  • energy efficiency
  • integration in the land
​Nuestra motivación para participar en el concurso es difundir los proyectos que hemos realizado con contenedores marítimos reciclados, cuya concepción y diseño están basados en las 4R:

* Reducir los objetos de consumo

* Reutilizar los que ya hemos usado

* Reciclar los productos dándoles otra finalidad

* Research (investigar).

Hemos utilizado preferentemente materiales de origen natural y de bajo coste de transformación y reciclaje, sin caer por ello en planteamientos radicales que supongan ineficiencias o costes inasumibles.

En nuestros proyectos de edificios pasivos hemos valorado el ahorro energético respeto el edificio estándar de referencia, el coste por metro cuadrado (565m2) y las emisiones de GEI en la etapa de uso, estos datos han sido cuidado al extremo y nos llevaron a ganar el premio al caso de estudio más ecoeficiente de Construction 21 en su edición del 2014.
