Development of methodology for performance evaluation of mechanical ventilation in recently renovated or newly built homes in Greenland

In this project we will select a minimum of 6 case homes in Greenland that were recently built or renovated and equipped with balanced mechanical ventilation with heat recovery. We will then develop and test a methodology for system performance evaluation. Using this methodology, we will study the design, performance, indoor air quality and user experience with ventilation systems. Afterwards, we will use the experience from the case study to adjust the methodology and make it applicable to other buildings and regions. Simultaneously, we will use the obtained knowledge in combination with input from local stakeholders to overcome new and known challenges such as:
• Lack of reference data for ventilation system performance in the Arctic
• Problems with insufficient air change or over ventilating of indoor space
• Frost and snow protection efficiency

The main objectives of our project are therefore:
• Develop a methodology for performance evaluation of mechanical ventilation in Greenlandic homes. The methodology should include necessary measurements and technical inspections as well as key performance indicators and procedures for data analysis.
• Map the situation related to real life performance of mechanical ventilation in Greenlandic homes, focusing on new and renovated buildings. Characterize typical operational issues and indicate possibilities for improvement.
• Disseminate the project results to local installers, ventilation designers, researchers and engineering students in Greenland and wider Arctic
