How to fill out multifamily envelope leakage model

How to fill out multifamily envelope leakage model

1. Start by gathering all the necessary information such as the floor plan of the multifamily building, the location of the envelope components, and any existing data on air leakage in the building.
2. Determine the testing protocol to be followed. This may involve conducting blower door tests on individual units or on the entire building.
3. Set up the necessary equipment for the blower door test, including the blower door fan, pressure gauges, and manometers.
4. Follow the testing procedures and measure the air leakage rates at various pressure differentials.
5. Record the data obtained from the blower door test, including the air leakage rates and the pressure differentials.
6. Analyze the data to assess the overall air tightness of the multifamily building envelope. This can be done by comparing the measured leakage rates to industry standards or benchmarks.
7. Identify any areas of concern or potential improvement based on the analysis of the data. This may involve pinpointing specific envelope components that contribute significantly to air leakage.
8. Develop a comprehensive report summarizing the findings of the multifamily envelope leakage model, including recommendations for improving air tightness and energy efficiency.
9. Present the findings and recommendations to the relevant stakeholders, such as building owners, property managers, or energy auditors, to facilitate informed decision-making.
10. Periodically reevaluate the multifamily envelope leakage model to track improvements over time and identify the effectiveness of implemented measures.
