The main goal of QUEST was to increase investments in Sustainability and Energy Efficiency of buildings by providing an easy-to-follow methodology for evaluating the risks associated with these investments. The risks attributed by investors to Energy Efficiency projects mainly stem from insecurity around the energy and cost savings, since predicted energy savings are unfortunately very often much higher than the actual savings achieved.
Within QUEST this issue has been tackled by identifying and empirically risk-grading factors that influence energy performance of buildings. Leveraging existing data and QUEST-led stakeholder workshops, QUEST has created an Energy Efficiency risk appraisal method to de-risk investment decisions through the integration of effective quality management services into Energy Efficiency projects:
• QUEST drafted an online-tool, the QUEST tool, that allows the approximation of cost and added value of quality management services for any given building project. Due to the minimal information required for the estimation, the tool can be used in early stages of real estate development to have budgets for quality management services properly allocated (https://quest-tool.synavision.de/ ).
• QUEST also drafted a methodology, the QUEST data engine, to evaluate the added value of quality management services using pre- and post-project evaluations. These cover basic panel data (like size, occupancy rate, operational expenditures etc.), questions on the perceived technical and financial performance of a project as well as technical testing of systems.
Both approaches combined shall be used to continuously strengthen and evaluate the success of projects including data on the added value of quality management services for buildings.
The QUEST process will help financial institutions to improve risk premium calculations reliability. The core element is the online QUEST tool. Its application allows users predicting quantitatively the impact of quality management services like certification schemes (BREEAM, DGNB, LEED etc.), building commissioning (LEED, COPILOT, ICP etc.), Monitoring (AMEV, LEED etc.) on building projects. A corresponding data set for documentation, the QUEST data engine, will continuously improve the underlying empiric evidence.
As a practical and reference document, the project created the QUEST Technical Manual. It explains the underlying technical causes of quality deficits, gives guidance for the application of Quality Management Services, introduces into the application of the QUEST Tool and Data Engine, and provides templates for tender documents and procurements. Their application will help to remove risks from green investments and bring about success in the green transformation of European building stock.
