COVID-19 had a major impact on the 2030 Agenda for Sustainable Development, and it produced a crisis in Goal 4, which is aimed at ensuring quality education, among others. In this work, a university experience that aims to solve the challenges in this complicated context by means of BIM technology is presented. On the one hand, this study focuses on the development of teaching by means of active methodologies based on real projects through BIM models, using the latest information and communication technologies, and on the other hand, it focuses on the management of the education center by means of a virtual BIM building. This allowed for, among other things, tackling the sustainable management of the measures required to prevent contagion. These BIM models made it possible, for example, to optimize spaces while maintaining social distances between occupants, to simulate the best options for classroom ventilation, and to optimize special cleaning and disinfection resources. Students who developed their learning through these BIM virtual models were not restricted in receiving online classes; they learned to collaborate from anywhere in the world, acquiring skills that allow them to effectively face real situations that are as complicated as COVID-19.

Red Ereño is widely prized as an ornamental and construction stone for its intense red micritic matrix, contrasting with the white rudist fossil shells it contains. Quarried since Roman times (first century) in the localities of Ereño and Gautegiz Arteaga, Red Ereño is a recognised limestone and has been widely used in architecture ever since. It was utilised extensively in the Basque Country and is characteristic of the urban landscape of several of the region’s most important cities, including Bilbao and Gernika (Guernica). It has also been used in many monumental and other buildings throughout the Iberian Peninsula. Red Ereño limestone has also been exported to the Americas and Italy, the most significant example being its use in the flooring of St Peter’s Basilica in the Vatican. This paper summarises the main features of Red Ereño as a candidate for consideration as a Global Heritage Stone Resource (GHSR). This recognition will be important for future research and restoration works of existing heritage buildings.

Bearing in mind that dwellings generate a high environmental impact, the aim of this research is to improve their energy efficiency. The incorporation of an insulating layer in the extrados of the building envelope is the most effective way of reducing the transmittance of a facade, eliminating thermal bridges, and optimizing its energy consumption. There is no doubt about the effectiveness of this solution in terms of thermal protection. However, this process collides with the preservation of the original composition of buildings with ornate facades. This article presents a protocol for the rehabilitation of ornate facades of historic buildings through the application of an insulating layer on the outside of the walls. The protocol shows that advanced techniques applied with an integrated approach permit compatibility between energy rehabilitation and the preservation of the original value. In addition to applying strategies of a high technological level, the protocol proposes a reflection upon a balanced intervention on ornamental elements, as well as the relationship between the degree of energy improvement of an ornate facade, and the degree of preservation of the original composition. A methodology is established that combines different avant-guard techniques and systems. These include capturing reality in 3D, the Building Information Model (BIM), monitoring, advanced manufacturing, and active and passive solution simulations.

This paper presents a methodological approach for the study of the early historical buildings constructed in reinforced concrete at the beginning of the 20th century. These buildings were conceived following different patents that, already in origin, made them unique and diverse. Also, the structures had to be adapted to their constructive context. Nowadays, aiming to evaluate and recuperate these buildings is necessary to develop a sequence of systematic study, which combines a historical review of the construction, its architectural characterization, its geometrical definition and its geological context. In this transdisciplinary approach, the geophysical studies based on ground-penetrating radar, as a non-destructive technique, facilitate the recognition of building structural details. The proposed working-approach attends to understand the construction (WHAT?) from its first designs to its final execution, including the characterization of current alterations. This requires the symbiosis of different disciplines (HOW?) that will be the basis for new projects aimed at the re-functionalization of buildings (WHAT FOR?), respecting their original values. The application of the methodology in Punta Begoña Galleries (Getxo, Basque Country, Spain) allows validating this approach, which can be extrapolated to other contemporary constructions.

The architectural activity in the construction stage, may be simplified into two distinct phases. On one side is the pre or conceptual phase, and secondly, the realization or execution phase. It can be ensured that there have been three historical stages in how to generate the graphic documentation of the conceptual phase: 1. Pre-Digital stage; 2. Digital stage; 3. BIM stage. It delves into the advantages and disadvantages of each of the three methods, in a comparison of execution times, rates of use of the tool in teaching and its reflection in the educational and professional fields.

Bi auzik eragingo diote datozen urteotan eraikiriko ondarearen birgaitze energetikoari: aurretiko eraikin eta bizitetxeen gainean energia-eskaera murrizteko helburuz esku hartzeko beharrak, batetik, eta eraikiriko arkitektura-ondarea zaintzeko beharrak, bestetik. Esku-hartze eta birgaitze-estrategiek, baina, energia-eskaeraren murrizketa beste helbururik izan ezean, luze gabe gerta liteke geure parke eraikia itxuraldatua suertatzea, jatorrizko arkitektura-ezaugarriak erabat galduta. Horrez gain, gure herri eta hirietako parke eraikia babesteko arauek eta legeek ezinezkoa eginez gero etxe eta eraikinen birgaitze energetikoa aurrera eramatea, ez da Europar Batasunak ezarritako helburuekin konplitzerik izango. Lan honek mutur bi horien arteko dialektikari erantzun mailakatua ematea du helburu. Alde batetik, bost esku-hartze maila proposatzen ditu. Maila bakoitzak jatorrizko eraikinaren izaerari eta inguruabarrei erantzuten die, eta maila bakoitzari, noski, kontsumo-hobekuntza jakin bat dagokio. Beste aldetik, gure herri eta hirietan ohikoenak diren etxe tipo nagusiak hartzen ditu saiakuntza-bankutzat, esku-hartze maila ezberdinen eragina neurtzeko.
