Alongside potential improvements in inspection efficiency, safety and reduced vehicle use, it addresses operational constraints, weather limitations, staff training and coordination with air traffic control. The report provides a foundation for future deployment, while noting that routine operations still require the necessary safety assessments and authorisations.

This report examines whether solar panels installed on a passenger boarding bridge at Paris-Charles de Gaulle could cause visual disturbance for pilots or air traffic controllers. The installation is designed to charge battery-powered ground power units supplying aircraft during stopovers. The assessment considers panel positioning, surface area, low-reflection characteristics and proximity to the control tower, concluding that significant glare is unlikely in this configuration. A subsequent review of reported glare incidents found none associated with photovoltaic panels during the period examined, supporting the initial assessment and informing possible wider deployment.

This report applies OLGA’s terminal refurbishment methodology to Cluj-Napoca’s Arrivals Terminal through dynamic energy modelling, calibration, optimisation and a 50-year life-cycle assessment. As the building is already well insulated, the analysis finds that envelope improvements alone offer limited benefits and prioritises an integrated combination of glazing, shading, heat pumps and photovoltaic generation. The modelling projects reductions in annual net site energy consumption of up to 53.8%, requiring approximately €2.5 million in investment. A further scenario incorporating airport-wide renewable energy infrastructure offers the greatest potential carbon reduction, while increasing the environmental impacts associated with equipment production and replacement. The report also highlights the importance of detailed energy metering for reliable calibration and investment decisions.

This report demonstrates the replication of OLGA’s energy and environmental assessment methodology at Zagreb Airport’s passenger terminal. A building information model was adapted into a calibrated, 16-zone energy simulation, supported by a life-cycle assessment covering construction materials and operational energy. The study evaluates night ventilation, dynamic external shading, their combined application and solar-selective glazing. Combining shading with night ventilation delivers the strongest projected performance, reducing cooling demand by 19.9% and the global warming impact associated with heating and cooling by approximately 16%, despite a small increase in heating demand. The report confirms the methodology’s usefulness for identifying improvements in modern airport buildings and provides a foundation for future investment planning, while documenting modelling challenges and limitations in available consumption data.

Terminal refurbishments at ADP generate significant waste, though many materials can be reused or recycled.
This report presents a joint experiment with BATIRIM using a 2D/3D digital interface to optimize material reuse. Part 1 covers methodology and tool development, Part 2 analyses data to identify reusable elements, and Part 3 summarizes results and conclusions.

The OLGA Communication & Dissemination Plan (D.7.1) outlines strategies and actions to share project results with target groups, civil society, and the media. This revised version clarifies roles and procedures and includes graphical illustrations of communication and dissemination steps.

This report explores how selected OLGA innovations could move beyond demonstrations into practical deployment and wider adoption. Using Business Model Canvas assessments and SWOT analyses, it examines value, users, costs, partnerships, scalability and implementation barriers across solutions such as SAF traceability, energy efficiency and hydrogen infrastructure. It distinguishes commercially oriented models from solutions requiring coordinated ecosystem investment and those delivering mainly strategic or operational benefits. Rather than claiming that all innovations are commercially proven, it identifies promising deployment pathways and remaining gaps, recognising that success can include emissions reductions, cost savings, compliance and improved airport operations.

Electric buses are key to reducing emissions, noise, and operating costs in airport–city and intra-airport transport.

This report presents an extended software solution, originally developed under the SOLEZ project and enhanced within PULSAR, to support optimal electrification planning for airport bus systems and e-hubs. The tool enables simulation and optimization of e-bus fleets, charging infrastructure, and scheduling to minimize total costs and accelerate the transition toward sustainable airport mobility.

This report presents a software-based decision support system, developed under WP2.2, to optimize multimodal traffic and strategic mobility management. The tool leverages AI, big data, and advanced technologies to support cities, public transport operators, airports, and citizens in improving efficiency, reducing emissions, and enhancing overall mobility.

This report describes Air France’s conversion of diesel-powered passenger boarding stairs into electric equipment at Paris-Charles de Gaulle. It covers equipment selection, technical design, deployment and the reuse of existing structures and refurbished battery components. The approach extends equipment life, reduces fuel consumption and emissions, and improves working conditions through lower noise, vibration and exhaust fumes. At the time of reporting, 34 units were operational, with further conversions planned towards a 60-unit fleet. The report also identifies opportunities to apply the approach to other suitable ground-support equipment.

In 2018, Groupe ADP created a lighting guide for aprons to standardize performance across its airports. Initially covering power supply and on/off controls, the guide was updated with LED dimming and advanced monitoring to optimize energy use, reduce light pollution, and improve comfort, safety, and security on aircraft stands.

ADP’s Terminal Buildings are old and complex industrial buildings. Objectives of this sub-task are to develop an innovative methodology based on a software platform developed at ARMINES integrating building energy simulation (Pleiades STD Comfie) and life cycle assessment (Pleiades ACV Equer).

This report documents the partial replication of OLGA’s innovative airport lighting concept at Cluj-Napoca Airport. An assessment of the existing installation identified insufficient illumination, poor colour rendering and maintenance challenges, informing the development of an adaptable LED solution. Four prototype luminaires were installed in the connecting hall between Arrivals and Departures, with adjustable colour temperature, independently controlled direct and indirect lighting, and energy monitoring. The proposed wider installation of 39 luminaires would reduce installed power by approximately 77%, with dimming projected to bring electricity consumption down to 10–15% of the previous system’s consumption. The report presents a practical route towards improved passenger comfort, lighting quality and energy efficiency, with procurement, installation and further testing planned.

Cerib has conducted a study on behalf of Groupe ADP on the development of a low-carbon concrete formulation based on a so-called ternary binder (K-LL-Mk) as well as the associated LCA study, as part of the hOListic & Green Airports (OLGA) project, which is part of the European Green Deal. The results presented in this report summarize this work.

This report provides a framework for preparing airports to accommodate hydrogen use in aircraft and ground transport. Using Paris-Charles de Gaulle as its main case study, with replication guidance for Zagreb, it examines projected demand, supply chains, storage, liquefaction, distribution, refuelling and infrastructure integration. It also reviews airport regulations and identifies procedures requiring clarification or adaptation. The report highlights the importance of coordinated planning, land availability, safety and regulatory harmonisation, while acknowledging that detailed aircraft–airport compatibility checks were limited by the absence of final aircraft designs and that its planning assumptions predate revised aircraft-development timelines.
