Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. New Classrooms for the School of Economics at Murcia University in Spain by Ecoproyecta + Ad-hoc mslApril 20th, 2013 by Sumit Singhal
Article source: Ecoproyecta + Ad-hoc msl The design project for eight new classrooms for the School of Economics and Business at Murcia University, the result of collaboration between Ecoproyecta and Adhoc msl, has been defined from the beginning by sustainability criteria with respect to energy efficiency and material selection. The original building was designed and executed by the studio Adhoc msl and the architect Enrique Carbonell at the end of the 1990s. The general scheme of the building was determined by four classroom and office blocks, with east-west orientation, that cross with two perpendicular communication rooms, with north-south orientation.

To these criteria, Ecoproyecta added standards of sustainable construction, to accomplish a healthy, comfortable space, with a lower energy requirement.

The classrooms occupy the porches partially, and maintain the possibility of circulating through the plaza. The access to the classrooms from the exterior plaza revitalizes its use, and takes advantage of the benign weather in Murcia.

Therefore, instead of mimicking the construction in steel and concrete of the original building, the design of the extension, both formally and constructively, was realized independently.  Image Courtesy © Gabriel López The new classrooms follow the concept of dry and lightweight assemblage, with a structure comprised of laminated wood and prefabricated wood-cement panels in the exterior, and chipboard panels in the interior. Thermal insulation is achieved using natural cork and hemp fiber. Natural cork panels also contribute to acoustic conditions, in terms of insulation and reverberation, necessary for the comfort needed in the classrooms.  Image Courtesy © Gabriel López The lack of thermal inertia resulting of a lightweight construction system is compensated with thicker insulation. Each façade contains a layer of hemp fiber 8cm thick and a layer of natural cork 4cm thick. Added to the insulation capacity of the wood panels, a very low thermal conductivity is achieved. Thus, thanks to the low thermal conductivity inertia, the classrooms reach their comfort temperature quickly.

Openings on the north and south facades facilitate cross ventilation and natural lighting perpendicular to the orientation of the working plane. These openings are materialized with skylights that give the project its emblematic image.
