With this modular SaaS platform, the Berlin-based climate tech company supports real estate industry players in the energy-efficient and strategic transformation of their properties.

From rising CO₂ costs to an efficient recovery plan: The most important functions of the Green+ Portal

Starting in 2027, with the transition from national emissions trading to the EU-wide ETS-2 system, supply and demand for emission certificates will determine the price of _CO2 . Experts expect price increases of up to 600 percent or more. Owners of particularly energy-inefficient buildings already have to bear up to 95 percent of the resulting CO2 costs themselves. Energy-efficient refurbishments are therefore unavoidable for many properties. However, until now, the industry has lacked a holistic digital solution to efficiently combine complex data analyses, action planning, and project implementation. 

With the Green+ Portal, Purpose Green addresses this problem and creates a consistent digital environment for assessing the current energy status, planning measures, and providing structured data relevant to refurbishment and ESG. In addition to owners and managers of existing properties, this holistic solution primarily benefits brokers, financiers, and market participants who work with numerous properties and their energy and ESG-related data in their day-to-day business. 

In the future, project management will be fully digitalized for transparent processes with live updates directly from the construction manager. The Green+ Portal already offers easy access to flexibly combinable modular solutions that cover different functions depending on requirements and can be precisely tailored to individual property needs:
‍

• Energy Light Report : This feature provides a digital initial assessment of a building's energy performance, including a forecast for the development of its energy efficiency class, CO₂ costs, and refurbishment costs. It also includes information on possible funding opportunities.
  
  
• Energy-saving measure configurator : This module allows various refurbishment scenarios to be simulated in real time, tailored to the needs of owners and customers. Costs and funding options are dynamically calculated based on the selected measures and presented in an interactive 3D model. This allows for data-driven optimization of consultations.
  
  
• ROI Calculator : This tool, integrated into the Green+ portal, automatically evaluates the cost-effectiveness of individual packages of measures at the property level, taking into account investment costs, savings potential, CO₂ taxes, and available subsidies. This ensures that profitability remains the focus of every decision.
  
  
• Data Room : Files such as property brochures, energy performance certificates, or funding documents can be stored in a structured manner for each property via the Data Room and accessed on a project-by-project basis. All files are available to all project participants in the team, centralizing communication on a property-by-property basis.

Flexible subscription model for every usage scenario

The Green+ portal's pricing model is not based on the features used, but rather on the number of buildings activated for full functionality. Even with a free basic access, you can digitally record your first buildings. The Starter subscription is suitable for smaller portfolios with individual buildings, while the Growth subscription, with at least 20 properties, allows cost-effective access for processing more extensive data rooms and analyses. For real estate companies with over 100 properties, a customized Enterprise plan is available upon request.

"We developed the Green+ Portal to enable all stakeholders in the real estate sector to make data-based decisions regarding energy efficiency and to make necessary refurbishment measures as understandable, calculable, and implementable as possible. Whether it's assessing the current energy status, developing realistic refurbishment scenarios, or providing structured ESG documentation for banks and funding programs: all of this can be mapped out via the Green+ Portal.
For Engel & Völkers Commercial, we've already been able to use the portal to supplement over 1,000 market price estimates with relevant data on CO₂ emissions and savings potential. The areas we analyzed cover over two million square meters – this demonstrates the great demand for such solutions in the market and the added value our product offers the industry," says Daniel Schreiner, Head of ESG & Construction at Purpose Green.
