Tertiary Sector Decree

Also known as the Tertiary Sector Energy EBiciency Decree (D-E-E-T), this regulation requirescommercial buildings to progressively reduce their energy consumption (-40% by 2030, -50% by 2040, -60% by 2050). In short: energy savings. Rooftop solar installations contribute directly and help achieve these targets.

APER Act

Act on the Acceleration of Renewable Energy Production. Key requirements: Art. 40 – Install solar canopies that generate renewable energy over outdoor parking lots of ≥1,500 m.; Art. 43 – Install solar panels or green roofs on existing buildings according to thresholds specified by decree. In short: accelerated deployment. Installing solar panels on parking areas and roofs ensures compliance.

A single partner to turn your real estate portfolio into a source of renewable energy.

Accelerating
the energy transition...
on a large scale.

40% of global CO₂ emissions come from the real estate industry. Time for change, right?
Every unused rooftop is an opportunity to generate local, clean, sustainable solar energy and that means more natural spaces preserved.
Through self-generation and self-consumption, we create a double impact: greater value for owners, greater benefits for tenants, and long-term appeal for assets.

Let’s talk about
your real estate assets

Do you manage a property portfolio? Are you looking for a simple solution to comply with the Tertiary Sector Decree, the APER Law (parking and rooftop coverage), and improve your CSRD reporting? Let’s discuss.

Understanding the Regulations

What requirements must real estate companies meet to decarbonize their property portfolios?

Decarbonizing real estate assets is no longer an option for real estate companies: Several major regulations now mandate a reduction in carbon-based energy consumption and improvements in buildings’ carbon performance:

  • The Tertiary Sector Decree sets ambitious targets: -40% energy consumption by 2030, -50% by 2040, and -60% by 2050, compared to a baseline year between 2010 and 2019.
  • The CSRD (Corporate Sustainability Reporting Directive) requires detailed and standardized reporting on ESG (Environmental, Social, and Governance) impacts, expanding the number of companies concerned from 2024 onward.
  • The EU Taxonomy promotes and values low-carbon assets within investment and financing strategies.
  • The APER Law (Acceleration of Renewable Energy Production) requires the integration of solar energy production or green roofs on buildings and parking areas.

In this context, solarizing rooftops and parking areas offers a fast, cost-effective and efficient way to meet regulatory requirements without the burden of managing the process. Generating renewable energy locally reduces grid dependency and the carbon footprint of real estate assets. With our Solar as a Service model, property owners can accelerate their energy transition with zero upfront investment (zero CAPEX) and no operational complexity, while enhancing the value of their real estate portfolios.

Yes. Installing solar panels on a building is now widely recognised as an eBective way to enhance its value. By producing renewable energy locally, a solar-powered building becomes:

  • More attractive to occupants and users, thanks to reduced energy costs and longterm security of electricity prices.
  • More competitive in the market, whether for commercial buildings, industrial facilities, or residential properties. In fact, buyers and tenants are increasingly sensitive to carbon footprint and energy performance.
  • Better rated in regulatory assessments, such as the EPC (Energy Performance Certificate), which directly impacts both rental value and resale value.

For real estate investors and property owners, rooftop solarization. also represents a strategic advantage for improving their non-financial (ESG) ratings and complying with regulatory requirements (the Tertiary Decree, the APER Act, and the CSRD).

With our Solar as a Service model, you can unlock this value with no upfront investment, without increasing your debt or mobilizing internal resources. We handle the entire project: studies, financing, installation, maintenance, and optimization; ensuring fast and measurable results.

In short, photovoltaic panels are a smart investment to enhance the value, sustainability, and competitiveness of your real estate portfolio, while actively contributing to the energy transition.

Solarizing a commercial building typically takes between 12 and 18 months, from the initial feasibility study to the commissioning of the photovoltaic system. This timeframe includes all stages: design, technical studies, administrative procedures, and grid connection.

Thanks to Projection Solar, our proprietary technology, we automate the identification of solar-ready surfaces, accurately assess solar potential, and streamline administrative file preparation. The result: several weeks saved compared to a traditional solar project.

Timelines may vary depending on:

  • The size and architectural complexity of the building,
  • Urban planning or heritage constraints,
  • Site access conditions and grid connection requirements.

With our Solar as a Service model, you benefit from end-to-end project management, a fully controlled timeline, and implementation without mobilizing your internal teams. Our commitment: reducing the average solarization timeline by 50% through our optimized and automated approach.

Choosing solar means accelerating the energy transition of your real estate portfolio while meeting regulatory requirements and sustainably enhancing the value of your assets. Contact us to assess your project.

Opting for leasing or the “Solar as a Service” model rather than a direct purchase is a gamechanger for commercial real estate stakeholders.

  • No upfront investment
    Avoid heavy CAPEX that strains your budget. The provider handles the installation and maintenance of the panels, allowing you to allocate your capital to other strategic projects.
  • No impact on your borrowing capacity
    By preserving your credit lines or debt capacity, you maintain your financial flexibility for other acquisitions or priority renovation projects.
  • 100% deductible operating expenses
    Leasing is treated as an operating expense rather than a capital investment. This provides a direct tax benefit, as lease payments are fully deductible, optimizing your operating results.
  • Immediate gains and budget visibility
    You benefit from reduced energy costs as soon as the system goes live, without having to wait for the long payback period associated with a traditional purchase. With a fixed, predictable monthly payment, you maintain full control over your costs.
  • Energy generated on-site and consumed on-site can be excluded from Tertiary Sector Decree calculations.
    This mechanically reduces your reported energy consumption, making it easier to achieve the -40% target by 2030.
  • ESG and financial value creation
    A Solar as a Service solution enables you to quickly improve your carbon footprint and ESG performance, enhancing your attractiveness to investors and tenants while increasing asset value.

In summary, leasing your solar panels transforms a regulatory obligation into a driver of economic and environmental performance, without complexity or capital tied up. A smart and sustainable strategy for the commercial sector.
