Popular software options include EnergyPlus and eQUEST, which can help identify potential energy savings and optimize system performance. When using these tools, ensure that the input data is accurate to achieve reliable results.
Infrared thermography cameras
Infrared thermography cameras detect heat patterns and temperature variations in buildings. These cameras can identify insulation deficiencies, air leaks, and moisture issues that contribute to energy loss.
During an audit, auditors can use these cameras to quickly assess large areas, making them efficient for identifying problem spots. It’s essential to conduct thermographic inspections under specific conditions, such as during colder months, to enhance visibility of heat loss.
Blower door tests
Blower door tests measure a building’s airtightness by creating a pressure difference between the inside and outside. This helps identify air leaks that can lead to increased energy consumption for heating and cooling.
During the test, a fan is mounted in an exterior door frame, and the building is depressurized. The results indicate how much air escapes, allowing auditors to recommend sealing strategies. Aim for a leakage rate that meets or exceeds local energy efficiency standards.
Data loggers
Data loggers collect and store energy usage data over time, providing insights into consumption patterns. These devices can monitor electricity, gas, and water usage, helping to identify trends and anomalies.
When selecting data loggers, consider factors like measurement range and battery life. Regularly reviewing logged data can help track the effectiveness of implemented energy-saving measures and inform future audits.
