International Collaborations in Green Training Programs

International collaborations in green training programs are structured around multilateral initiatives that transfer knowledge and best practices between countries. The BUILD UP Skills program (funded by the European Commission since 2011, cumulative budget of 50 million EUR) has been the most ambitious initiative globally: it has trained more than 100,000 construction workers across 30 European countries in energy efficiency, renewable energy, and nZEB construction competencies. In Spain, the BUILD UP Skills Spain (BUS-E) project developed a national qualification roadmap (2013) that identified a gap of 200,000 qualified workers in energy retrofitting.

The Horizon Europe program (2021-2027, budget of 95.5 billion EUR) funds research and innovation projects in sustainable construction through Cluster 5 (Climate, Energy and Mobility) and the mission "Climate-Neutral and Smart Cities" (100 European cities carbon-neutral by 2030). Relevant projects include: INSTRUCT (Innovative Education for Sustainable Construction, 2022-2025, 3.2 million EUR, 8 universities from 6 countries, developing LCA and BIM training modules for engineering degrees), nZEB Roadshow (traveling nZEB construction training for workers across 12 countries), and Train-to-nZEB (training centers with nZEB demonstration buildings in Bulgaria, Romania, Turkey, and Ukraine, 4,000+ workers trained). The New European Bauhaus (NEB, launched in 2020 by Ursula von der Leyen) integrates sustainability, inclusion, and aesthetics, with educational programs at 15 European universities.

Bilateral cooperation agencies fund green training programs in developing countries. The GIZ (Deutsche Gesellschaft fur Internationale Zusammenarbeit) operates building energy efficiency programs in over 30 countries: the PEEB (Programme for Energy Efficiency in Buildings) has provided technical assistance and training to ministries, developers, and professionals in Mexico, Morocco, Senegal, Vietnam, and India, with a budget of 35 million EUR (2017-2025) and more than 5,000 professionals trained. The GIZ-NAMA Facility project in Mexico funded the training of 2,000 architects and engineers in sustainable housing design compliant with the NOM-020-ENER standard.

The JICA (Japan International Cooperation Agency) operates training programs in disaster-resilient and energy-efficient construction across Southeast Asia and the Pacific. The AECID (Spanish Agency for International Development Cooperation) has funded sustainable construction training projects in Latin America, including the "Arauclima" program (climate change in Ibero-America, with a sustainable building component in Colombia, Peru, and Ecuador). The AFD (Agence Francaise de Developpement) funds the SUNREF (Sustainable Use of Natural Resources and Energy Finance) program, which includes building energy efficiency training in sub-Saharan Africa and the Mediterranean, with more than 3,000 professionals trained and 250 million EUR in green financing mobilized (2010-2023).

Academic networks facilitate knowledge transfer between universities and research centers. The PLEA (Passive and Low Energy Architecture) network, founded in 1982, brings together more than 1,000 researchers from 60 countries and organizes an annual conference (2,000-3,000 attendees) that serves as the primary scientific exchange platform for bioclimatic architecture and passive design. The SBE (Sustainable Built Environment) network, coordinated by CIB (Conseil International du Batiment), organizes regional conferences and the triennial World Sustainable Built Environment Conference (WSBE), with 3,000+ participants.

The EU's Erasmus+ program funds the mobility of students and lecturers between European universities: in the field of sustainable architecture and construction, more than 5,000 students per year undertake 3-12 month stays at universities in other European countries (European Commission, 2023). European university alliances such as ECIU (European Consortium of Innovative Universities) and ENHANCE (which includes UPM Madrid and TU Berlin) develop joint master's programs in sustainability with double or multiple degrees. The AECOM Foundation funds research scholarships in sustainable cities for students from developing countries, with 50+ annual scholarships of 10,000-30,000 USD.

Multilateral organizations coordinate green training at a global scale. The UNEP-SBCI (Sustainable Buildings and Climate Initiative), now integrated into the Global Alliance for Buildings and Construction (GlobalABC), brings together 250+ members (governments, private sector, NGOs) and has developed the Global Roadmap for Buildings and Construction 2020-2050, which identifies the sector's training needs to achieve decarbonization. GlobalABC estimates that 80 million additional qualified workers are needed in the global construction sector to implement the energy transition in buildings (GlobalABC/UNEP, 2022).

The World Green Building Council (World GBC), with 75 national Green Building Councils, coordinates training programs adapted to each market: the "Advancing Net Zero" program has trained GBCs from 30 countries in net-zero-carbon building certification methodologies. The building sector's contribution to the UN's SDGs (Sustainable Development Goals) is cross-cutting: SDG 7 (affordable and clean energy), SDG 11 (sustainable cities), SDG 12 (responsible consumption and production), and SDG 13 (climate action). The EDGE (IFC/World Bank) program has certified more than 7,000 buildings in 80+ emerging countries and trained 4,000+ EDGE Experts through a free 5-day program, making it the leading green training platform for developing markets.

Demonstration projects combine training with real construction to maximize knowledge transfer. The NEST (Next Evolution in Sustainable Building Technologies) program from Empa (Switzerland) operates a modular research building where international teams test innovative technologies (adaptive facades, energy modules, circular economy modules) with open access to performance data. The Solar Decathlon (DOE, USA, since 2002; European edition since 2010) is an international university competition where teams of 15-25 students design and build a solar house: Solar Decathlon Europe 2022 (Wuppertal, Germany) featured 18 teams from 11 countries, training 400+ students in integrated design, prefabrication, and solar energy.

In Spain, the AZEB (Affordable Zero Energy Buildings) project (Horizon 2020, 2017-2020) trained professionals from 5 countries in the design methodology for affordable zero-energy buildings, with 3 demonstration buildings constructed. The LIFE CITYnvest program funded the training of municipal officials from 9 European countries in implementing energy retrofit programs with innovative financing (EPC, ESCO, PACE). Training centers with demonstration buildings, such as the BRE Innovation Park (Watford, UK, 8 visitable demonstration buildings) and the EnergieSprong Lab (Netherlands, housing renovation to Net Zero Energy in 10 days), accelerate the transfer of innovations from the laboratory to construction practice.
