Buildings contribute approx. 36% to global CO2 emissions. Building operations have effects in many other areas that have a long-term impact on our environment. In order to meet reporting and corporate disclosure requirements, blue auditor provides automated data entry and continuous processing of ESG data so that the status quo can be evaluated and long-term goals can monitored. Benchmarking on asset and portfolio level gives additional insights for optimizations.

Project management for Green Building Certification

blue auditor provides a green building certification platform that is very different from existing providers focusing mainly on the submittal process and on a single certification system. After many years of first-hand experience, working with many certification systems, we have developed a platform that meets the needs of all stakeholders in the certification process:

blue auditor prioritizes simplicity, collaboration and transparency, clearly communicating and visualizing optimization measures that increase sustainability in real estate. With blue auditor, project developers and asset managers have a hands-on tool to manage sustainability certification and allow benchmarking across portfolios, enabling the first portfolio-wide approach across the three internationally recognized labels DGNB, LEED and BREEAM in the market.

Climate Risk Analysis, Facility and Portfolio Risk Scoring

In partnership with Four Twenty Seven, blue auditor provides science-driven climate risk analytics to create more awareness for project developers and asset managers to navigate climate change-related risk and to deliver unique insights into the economic impacts of climate change. Within blue auditor, users have the ability to perform climate risk analysis for single assets or for entire portfolios and provide climate risk scores across various locations. The climate risk assessment is available as a stand-alone feature or as a built-in evaluation tool in blue auditor’s EU taxonomy assessment functionality. Taking climate change into account, project developers can implement required mitigation measures during the design stage to reduce the risk of early CapEx measures of a newly built asset, while asset managers are able to assess whether their CapEx measures are aligned with potential future climate risks, allowing them to re-prioritize specific measures to reduce stranding.

Building Audit for CapEx aligned with Sustainability Goals

blue auditor provides a building audit solution that combines the classic CapEx approach with deficiency management and rates key performance indicators such as health and safety, energy efficiency, building structure, MEP systems, building documentation, facility management quality and overall alignment with sustainability objectives. The integrated deficiency management tool supports property and asset managers in the process to manage, implement and act on building deficiencies. 

The objective of the building audit functionality is to align CapEx measures with CO2 emission reduction targets over a specific period of time, reduce and assess stranding risk and enable the transition of brown assets to sustainable, performing assets.
