Awarded LEED Gold certification, the Entegra building optimizes its energy resources and promotes wellness programs for its users. The arrangement of terraces on each floor intensifies the relationship between the offices and the outdoor spaces, which are characterized by the warmth of the wood and the presence of vegetation.

Project description by Batlleiroig
Entegra is an almost zero consumption office building developed by Urban Input and designed by Batlleiroig in 22@ that promotes the sustainable mobility of its users and the relationship with natural elements in the work environment.
After its recent completion, Entegra is the first office building with a charred wood façade in Spain. A diaphanous ground floor and eight floors totalling 4,138 m² of offices available in the technological district of Barcelona where innovation, sustainability and efficiency are its backbone.
The building incorporates an intelligent natural ventilation system that, together with other passive measures, allows it to be considered a nZEB building, in addition to having obtained the LEED Gold sustainability certification.
The vocation of the building is aimed at the well-being of users from the moment they start their journey to work, which is why the infrastructure is provided to promote the mobility of its users by bicycle. This commitment has made it possible to obtain the Cycling Friendly certification.
AN INNOVATIVE FACADE SOLUTION
In a strong commitment by the team to innovation, the building has a charred wood façade that follows the Shou Sugi Ban method. This traditional Japanese technique consists of burning the outer layer of wood, achieving a unique and attractive facade with very good properties. Applying a controlled burning of the wood ensures an excellent fireproof protection of the façade, as well as its protection against humidity, solar radiation and insect attack.
Thanks to this choice, the façade of the building is resolved with a highly durable natural system that has very low maintenance. An ancient technique adapted to the strict current requirements in an innovative way. In terms of sustainability, the use of wood represents a substantial reduction in the carbon footprint of the building, a commitment that the team assumes in each project. Each m3 of wood used stores approximately 1 ton of CO2. This fact, together with other measures that reduce the energy demand of the building, have allowed the project to obtain the LEED Gold sustainability certification.
This façade decision also influences the comfort of its users, since it confers well-being and warmth to the exterior spaces of the building. The arrangement of terraces on each floor intensifies the relationship between the offices and the outdoor spaces, which are characterized by the warmth of the wood and the presence of vegetation.
SPACES IN CONTACT WITH VEGETATION AND NATURAL ELEMENTS
Each space of the project is designed to provide well-being to its users. All floors have spaces in contact with terraces and vegetation, in such a way that biophilia is promoted and the relationship between offices and outdoor spaces is intensified.
Inside, the finishes are taken care of in detail and the installations and exposed slabs are maintained, incorporating an innovative formwork solution with an irregular texture to improve acoustic conditioning.
