Portugalete – Residential building
This residential building consists of a social housing oriented to low-income residents and developed by the Basque Government. The building has been designed as a passive solar house with a targeted annual energy use on 41,8 kWh per m². The design of the building also aims to minimize its environmental impact by using materials with low embodied energy and low environmental toxicity wherever possible.
Several energy efficiency measures will be implemented on the building:
- A parietodynamic wall, integrated with the building ventilation system, to maximize the energy storage in the façade
- An insulating painting with nanotechnology which is designed to insulate and waterproof the walls
- Green roofs, which provides insulation in winter and prevents overheating in summer
An energy display screen will be installed in each of the buildings, providing information on heating, lighting and electric energy consumption. This will be a tool for communicating with the residents and to make aware of their energy consumption to help to improve user’s behavior.
The social scope of the project is also important in this project as it is oriented for social housing. Therefore, the building will be low cost in order to be affordable for tenants of low-medium social class.
Finally the relationship among all the construction companies helps the introduction of the different technologies in other countries. Technologies that can be state of the art in one country can be innovative in other because they are not implemented and ready to be introduced in the market.
