Energy-intensive building

An educational building for university research that includes innovation in energy and sustainability in the building itself, in energy exchanges on the district scale, and measures to improve the health and comfort of users.

The objective was to build a functional, sustainable and multi-purpose infrastructure, capable of adapting to the diverse uses and changing needs of the University of Valladolid at the Soria Campus. The program required a flexible layout to allow simultaneously research-related activities, and training workspaces and derived activities, in accordance with the European Research Area and European Higher Education Area (ERA and EHEA, Bologna Process).

The 3,504.34 m2 project includes:  

  • classrooms complementary to the existing ones
  • offices and workplaces for faculty and staff
  • laboratories and mixed spaces for practical research and engineering

One of the prerequisites of the program was the adaptation to evolving educational patterns. This objective was put in practice with the outbreak of the COVID-19 pandemic: the building was opened precisely at that time, thus proving its adaptability to unforeseen circumstances. The laboratory was temporarily converted into classrooms and the ventilation system worked in accordance with the new health, social distancing and security needs.

Another issue of interest of this building is the innovative and radical approach of its design, in accordance with its close environment, seeking energy autonomy. The previous experience of this University in sustainable buildings and NZEB (LUCIA and INDUNIVERSIDAD DE VALLADOLID buildings in Valladolid), has been implemented and extended in the Soria Campus, improving the same principles. Universal accessibility, social criteria and circular economy have been considered, with special emphasis on local and healthy building materials (all with EDP, no VOC, partly recycled, no waste, etc.), and waste control and reuse. But the main aspect lies in the coordination between design and on-site renewable energy production to achieve NZEB targets.

This has been achieved based on a careful study of the site, its microclimate and its own resources, analyzing: 

  • solar radiation
  • topographic and geothermal characteristics of the soil
  • wind regime
  • water availability
  • shadows and the impact of nearby buildings
  • accessible energy in the environment

The result of the adaptation of the program and the requirements is two distinct volumes of different dimensions, orientation and design, each requiring its own particular combination of passive and active bioclimatic energy systems. In addition to the bioclimatic energy solutions and saving strategies (incidence of natural light lighting, low consumption devices and intelligent control systems, etc.), the use of an air conditioning and ventilation system based on an integrated design of renewable energies from the site has been added:

  • A solar wall, which is a new technical and experimental solution of solar radiation, as an air preheating system
  • Photovoltaic solar radiation integrated into the building for electricity production
  • Geothermal, in subway pipes
  • Local biomass central heating system

It is in the process of certification by the VERDE-GBCe and LEED methods, opting for the best results (in process, 5 GREEN and Platinum LEED leaves).

Owner approach of sustainability

The University of Valladolid has been carrying out a campaign for sustainability for a decade. It applies innovative systems in buildings with zero energy consumption (NZEB, national and international awarded) and simultaneously disseminates these achievements to students, educational staff and management of the University. It is a way to present, in a direct and practical way, zero-carbon solutions and sustainable attitudes in general. The building is itself an educational subject as it is part of the academic curricular subject, especially in the schools of engineering and architecture.

Architectural description

The topography, very pronounced, and the shape of the site, semicircular surrounded by other university buildings, suggests different levels and shapes in the design of the building and its connection with the other buildings of the Campus on the north face. The design team, the Directorate of the Technical Unit of Architecture of the University of Valladolid, planned two different volumes, according to the particular functional requirements. Renewable energy production was integrated into the building such that each façade (including the roof) has its own renewable energy system based on its solar orientation.

The main laboratories (910 m2) have a dedicated space, as they require large open spaces. The other laboratories (300 m2), offices and specialized classrooms and workshops (600 m2) are located in another volume, regular prismatic, of 2590 m2.

The southeastern facade of the volume of the laboratories is closed as it contains the entrance of trucks and houses an air-collector-solar wall. It is a system for heating air mainly in a passive way, which reduces the use of non-renewable energy and moderates the losses of the wall on which it rests.

Next to the southwest façade, semi-buried, are the corridors for classrooms and workshops. For this facade, energy is produced by photovoltaic solar panels, such that it simultaneously allows for natural lighting and ventilation, as well as sight of the outside.

The roofs are green and skylights are located to provide light to the underground spaces. Geothermal pipes are also provided to support air conditioning.

The exterior treatment of the facades, glazing and windows and coatings have been chose in accordance with the energy objectives.

If you had to do it again?

Wood has been used as a structure for laboratories in large beams. The architect director of the Technical Unit of Architecture recognizes that, if he had to rebuild the building, he would use structural wood more exhaustively, as it is an existing product in the region (the forests of Soria), because of its good quality and because of to promote economically the area and other social aspects derived from its industry. In addition to this, it would make the deck accessible.
Since the project was completed and construction began, important achievements have been made in terms of circular economy: this chapter could be subject to improvement.

Building users opinion

The outbreak of the COVID-19 pandemic has provided an opportunity to verify the building's ability to guarantee the health of its occupants. The result of the satisfaction survey of the occupants is expected, which mainly indicates the comfort, the views, the adaptability and the light of the building.

    Extract from the Project Report:
    "The system consists of taking advantage of the air that is heated in a small chamber controlled by the effect of solar radiation on a micro-perforated metal sheet.
    To do this, a second skin is attached to the facade of the building through which, in winter, outside air is circulated which, due to conduction, convection and radiation phenomena, raises its temperature between 15 and 40ºC before being introduced inside the building by means of the general air conditioning system or through a parallel network.
    This double skin, in addition to allowing free heating of air, cancels or reduces thermal losses due to the enclosure in which it is attached. In summer, the air is not forced into the chamber, which is why it acts as a ventilated façade, providing shade to the enclosure and allowing upward air flows. Although it is less studied, and the position is not optimal, this system would also allow, in the summer months, to reverse the operation and perform night cooling, which allows lowering the temperature inside the building using the effect of heat irradiation to clear night sky.
    The system is not totally passive, it requires a fan to force air in in winter, and it must be equipped with a control system that analyzes the exterior, interior and chamber temperatures to regulate operation. "

Smart Building

    The Building Management System (BMS) covers the entire intervention (laboratories and other parts of the building) and controls by monitoring the air conditioning, security, other facilities, etc., as well as the centralized control of the interior lighting installation, Through the Premium system of DALI technology, and its terminals (presence detectors, etc.), linked via TCP / IP protocol to the building control software.
