Public Sector
The Public Sector, which encompasses all administrations, hospitals, schools, universities, and public infrastructures, is characterized by functional diversity and a strong requirement for service continuity. Public buildings and the services they host are significant energy consumers, while also needing to comply with strict budgetary and regulatory constraints.
Greenhouse gas emissions in the public sector mainly come from heating, air conditioning, lighting, and IT usage, as well as from hot water production and the operation of technical equipment. The need to ensure comfort, safety, and service availability implies continuous and hardly compressible energy consumption.
In a market context marked by energy price volatility, pressure on public budgets, and tightening environmental regulations, energy modernization represents a strategic lever to improve the efficiency of public infrastructures while reducing their carbon footprint. The transition is no longer limited to reducing consumption: it now relies on a set of complementary levers integrating energy efficiency, electrification of uses, on-site renewable energy, and the development of energy flexibility through energy storage.
GreenYellow positions itself as a strategic partner for retailers to support this transformation.
Through a comprehensive and integrated approach, we cover the entire energy value chain for public-sector buildings:
- analysis
- design
- Financing
- deployment, and operational management of solutions
Our added value lies in combining consumption reduction, on-site decarbonized energy production, and flexibility of usage, with measurable results.
This approach reconciles economic performance, operational security, and reduction of environmental impact.
Improving energy efficiency and electrification of uses
Public buildings and infrastructures present significant potential for energy optimization, particularly due to repetitive usage patterns and standardized technical installations. Improving energy efficiency is a key lever to sustainably reduce consumption and costs.
This involves optimizing heating, ventilation, air conditioning, and lighting systems. Enhancing the performance of boilers and heat pumps, recovering heat from technical networks, optimizing distribution networks, and reducing losses in installations can generate significant savings while ensuring occupant comfort and safety.
GreenYellow supports government / public agencies across the entire energy value chain, without requiring any CAPEX from the client and with a performance guarantee.
Our comprehensive approach combines:
Reduction in Energy Consumption
optimization of industrial processes, waste heat recovery, improvement of utilities, thermal energy storage (eTES), and intelligent equipment control.
Electrification of end uses
Combined with storage solutions, electrification smooths out energy consumption and ensures the continuity of public services.
Transition to local green energy production
Public buildings and sites often have large roof areas and a stable consumption profile, which is advantageous for deploying local renewable energy.
This initiative also contributes to achieving carbon neutrality goals and to enhancing the image of public administrations as responsible organizations in the eyes of citizens.
Reducing energy bills
by consuming electricity produced on-site and monetizing excess energy via grid injection.
Benefiting from a turnkey model
with 0 € CAPEX and guaranteed performance, for a simple and secure energy transition.
Strengthening energy independence
and limiting cost volatility linked to fossil fuels.
Decarbonizing operations
by substituting a significant share of consumption with solar electricity.
Innovation | Energy Demand Management
Energy management in the public sector must consider strong constraints related to service continuity, occupant comfort, and equipment safety. Implemented solutions must therefore be reliable, secure, and non-intrusive.
Energy Storage
Smart management systems also enable real-time synchronization between photovoltaic production and site consumption, optimizing overall energy use.
GreenYellow is taking it a step further by developing microgrids
in partnership with Schneider Electric, enabling local, intelligent, and resilient energy management. This approach transforms energy into a
GreenYellow stands out with a proactive, modular approach, offering a platform of combinable or individually deployable solutions:
Solar farms, solar photovoltaic plants on rooftops or solar carports for self-consumption and feeding into the grid.
Energy storage solutions to smooth out peaks, ensure a reliable power supply, and maximize flexibility.
Cost and investment management
Public institutions are particularly sensitive to budgetary constraints and investment priorities focused on public service. In this context, the energy transition can be perceived as a challenge if it requires significant upfront investments.
The ESCO model provided by GreenYellow removes these constraints by providing a fully financed solution, requiring no CAPEX from the client.
GreenYellow handles:
Initial investment, with no CAPEX required from the client.
Design and engineering of installations.
Deployment and maintenance of equipment.
Operational monitoring and performance tracking.
This model allows administrations to immediately benefit from energy and financial savings while eliminating technical and financial risks. It accelerates energy modernization, making high-performance solutions accessible without complex budgetary trade-offs.
Regulatory compliance
The public sector operates within a strict regulatory framework, combining environmental obligations, energy performance standards, and safety requirements. GreenYellow supports clients locally to fully integrate these constraints into the design and deployment of energy solutions, ensuring regulatory compliance and high performance.
Thanks to GreenYellow’s support
Working alongside government / public agencies, our clients can be confident that they are strictly complying with applicable local regulations and staying informed of changes to maintain a high level of compliance.
Our expertise has been recognized since 2007; we conduct market monitoring that allows us to adapt our solutions to constantly evolving standards and ensure compliance with legal requirements regarding energy.
Our clients can count on GreenYellow to support them through this energy transition and to ensure that their energy management meets the most rigorous standards.
Awareness and Engagement
Public-sector stakeholders
The success of the energy transition relies on the involvement of technical and administrative teams. Staff, technical managers, and leadership must be made aware of energy issues and supported in evolving practices.
Developing a culture of energy performance is essential, while ensuring service continuity and occupant comfort, which remain top priorities in the public sector.
