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

BMS :

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.

GHG emissions

• GHG in use : 10,80 KgCO₂/m²/year
Methodology used :

Life Cycle Analysis

Eco-design material :

All installed products have been required either DAP or the Type I ecolabel, preferably Type III, certified recycled content (pre- and post-consumer), durability, reuse or recyclability, and VOC content, and must be produced within a 200 km radius from the center at the construction site. The sum of the percentage of post-consumer recycled material and half of the percentage of pre-consumer recycling must exceed 29%.
