Owner approach of sustainability

In 2007, the Urban Consortium of Mostoles Technology launched a Public Tender for the elaboration of a draft for the building of the Madrid Institute for Advanced Studies in Energy (IMDEA Energy) in the sector Pau-5 “Mostoles Technology”. We were the winner of this tender and as a result we elaborated the design of the project. The Madrid Institute for Advanced Studies in Energy was created on the initiative of the Regional Government of Madrid with the finality of promoting and realizing R&D activities related to energy, with a special focus on questions related to renewable energy and clean energy technologies. The building for the Madrid Institute for Advanced Studies in Energy (IMDEA ENERGIA) was conceived based on three conceptual proposals. It was decided to develop one of them on the land that was donated to the city of Mostoles, within the future “Mostoles Technology” park (Sector PAU-5). The final proposal was developed in close collaboration with the client, based on an environmental, energy and economic sensitivity approach. This culminated in a proposal designed to have a building able to operate for a long time, under changing conditions. These conditions could result from technological and social progress or changes in the current or future investigation being carried out by this Institute. All this without neglecting the particular character of this building representative of the research and development that takes place within it. It is also conceived under strict efficient economic parameters, essential for the durability and sustainability of the building. The project was a challenge for both the designers and the developers. We were faced with the design of a building that had to be energy efficient during its construction and its operation, as well as being economically and technically viable, but at the same time keeping in mind the purpose for which it was intended.

Architectural description

A modular building was conceived which could be expanded or divided without affecting its functionality or image. It was developed around a CORE on three levels, with an open space in the middle, used as an entrance hall and reception area and which houses the common administration, management and relaxation areas. This space favors and promotes interaction between the users, as a transit and meeting area, alma mater and heart of the building, both functional and symbolic. Restoring the house courtyard typology inside this space, covered by a large skylight, created a microclimate through the regulation of sunlight, ventilation and humidity. Around this central module, on all three floors, are coupled or juxtaposed in radial form MODULES harboring the research areas. These were conceived as containers free of vertical structure. This facilitates distribution or subdivision, which is more convenient in its long term use. On the roof of these modules, are placed technical rooms equipped with the technology needed for the generation of clean and renewable energy. In addition they provide a passive defense cover against excessive solar radiation. At the end of the plot and on both sides of the planned core service area in the building, the PILOT WORKSHOPS are located. These are used to set up experimental equipment or as annexes necessary for the development of planned activities. Special care has been taken when orienting the building, treating the different facades according to their function and orientation, looking for the best energy efficiency, seeking to integrate the summary of all renewable energies, by applying the criteria of bioclimatic architecture so that resources are optimized and energy losses are minimized. SUSTAINABILITY The IMDEA ENERGY building is designed and planned taking into account the premises of a Green Building, seeking maximum ENERGY RATING ("A") and fulfilling the requirements of a certification system for sustainable buildings. By selecting the LEED certificate developed by the Green Building Council in the United States (U.S. Green Building Council), obtaining a gold certification (LEED NC 2.2 gold). -In areas exposed to direct sunlight, the building has white “Emugrava” covered with SRI (Solar Reflection Index) greater than 78, to reduce the heat island effect. -The distribution and separation of space between classrooms, laboratories and offices is created by glass screens, which allow great flexibility, and better natural lighting and visibility, both from the inside and from the outside of each enclosure. -In the construction of the building, a high percentage of recycled materials have been used, such as steel, aluminum or glass. -Materials such as natural stone have also been used. For the concrete and ceramic materials, priority has been given to regional raw materials or local manufacturing. -The materials derived from wood are defined by the FOREST STEWARDSHIP COUNCIL (FSC) certificate.

Energy consumption

• Primary energy need : 168,90 kWhpe/m².year
• Primary energy need for standard building : 491,70 kWhpe/m².year

Calculation method : RD: 47/2007

Envelope performance

• Envelope U-Value : 0,39 W.m^-2.K^-1
More information :

The entire building envelope (blind facades, trims and roofs) was designed to give the building a very important passive protection that contributes greatly to the "ENERGY RATING" A.

Building facades are back-ventilated with 80 mm isolation and different exterior finishes: On the central nucleus and on the research module they are covered with lacquered sheets. The front of the auditorium is covered with Segovia Quartzite stone and the facade of the Pilot Warehouses are finished off with corrugated sheets. All of these have concealed fixations.

The curtain walls and woodwork, depending on the orientation of each façade, pose a different formal solution, which can be fixed parasols (facing south and east) or movable sunshades, with automated control systems (west).
