Green+ Portal: Refurbishment, ESG & energy at a glance
SaaS solution for data-based decisions
The demands on the real estate industry are increasing: Energy efficiency, ESG transparency and efficient refurbishment are no longer peripheral issues - they determine value development, financing and investment capability. However, while owners, estate agents and property managers are under increasing pressure, there has been a lack of holistic digital solutions that efficiently combine complex data analysis, action planning and project implementation.
With the launch of the Green+ Portal, Purpose Green is offering a unique platform that meets these requirements: A holistic, modular SaaS solution that combines analysis, planning and documentation relating to energy-efficient refurbishments, ESG control and efficient construction management in a digital environment.
The Green+ Portal - your access to holistic real estate transformation
The Green+ Portal was developed to enable all relevant players in the real estate sector to make data-based decisions about energy efficiency and sustainability for targeted real estate transformations - simply, scalably and efficiently.
Whether it's assessing the current energy status of a property, developing realistic refurbishment scenarios or providing structured documents for banks or funding programs: The Green+ Portal covers these requirements in a single digital system.
The focus here is on the modular structure - users can use exactly the tools and functions they need for their individual purposes.
From the CO₂ profile to the restructuring plan: The most important functions at a glance
One of the most popular features of the Green+ portal is the Energy Light Report. With just a few clicks, the tool provides a precise initial assessment of a building's energy efficiency - including a forecast of CO₂ prices, refurbishment costs and the resulting potential changes in heating costs and energy efficiency class. An initial estimate for possible subsidies is also included. Real estate agents in particular value the Energy Light Report due to the advantages it offers in the sales process, as they can provide their customers with directly prepared information on the challenges and potential of their properties.

The energy measure configurator simulates customized refurbishment scenarios in real time - with flexibly adaptable strategies, including dynamic calculation of costs and funding options and visually supported with an animated 3D model. This creates planning and investment security. In addition, players in the real estate industry, such as estate agents or financiers, are given an effective tool for advising owners.
Another key feature is the ROI calculator. It evaluates the profitability of individual packages of measures, taking into account investment costs, potential savings, CO₂ levies and available subsidies. This turns a construction measure into a well-founded business decision.
The offering is rounded off by the Data Room - the digital file repository for all ESG and refurbishment-related documents. Whether exposés, energy performance certificates or funding documents: all parties involved receive secure, structured access to the latest data.
Added value for owners and brokers
The Green+ portal was developed specifically for two key user groups in the real estate industry: Portfolio holders - this includes owners and investors with their asset managers and administrators who want to develop their properties in a value-preserving manner. On the other hand, the portal is aimed at transaction players in the real estate industry, i.e. non-portfolio holders such as brokers, financiers and project partners who advise their clients with professional expertise.
The portal offers owners a scalable solution for the holistic digital management of their refurbishment and ESG strategies. On the portal, they can find their individual portfolio overview with live dashboards and planning modules. Instead of relying on manual Excel evaluations, measures can be systematically prioritized, evaluated and implemented.
Transaction players benefit from being able to provide their customers with concrete information on the current energy status and the expected refurbishment costs and subsidies for the property during the initial consultation - based on valid data, simple, clear and immediately available.
Over 900 market price assessments have already been supplemented with the help of the Green+ portal with regard to CO₂ emissions and savings potential for Engel & Völkers Commercial. The analyzed and evaluated data covers an area of more than 2 million square meters. (Status: May 2025)
Flexible subscription model for every usage scenario
The Green+ Portal was developed from the ground up with the aim of offering maximum flexibility for owners and investors, but also for asset management and real estate management. The Green+ Portal pricing model is not based on the features used. Instead, the price for the subscription in the annual contract is based on the number of licensed buildings. This makes the use of the Green+ Portal economically scalable for both individual buildings and extensive portfolios.
Even with the free Basic access, the first buildings can be created and managed digitally - ideal for an uncomplicated start. The Starter subscription is suitable for smaller portfolios with individual buildings, while the Growth subscription with at least 20 licenses allows cost-efficient access to more extensive data rooms, import functions and analyses. For real estate companies with over 100 properties, the Enterprise plan offers tailored license packages and extended support to meet individual requirements.

Conclusion: A holistic solution, modularly available
With the Green+ Portal, Purpose Green is launching a solution that not only closes technological gaps, but also creates real added value, both for private portfolio holders and for institutional investors, brokers and partners.
If you want to effectively integrate ESG, energy-efficient refurbishment and value creation into your work processes, the Green+ Portal is the ideal solution. The platform can be used immediately. If required, our team of experts will be happy to assist you.
