Air Sealing refers to the process of preventing air leakage in buildings by sealing gaps and cracks in the building envelope. This skill involves the identification and application of appropriate materials and techniques to enhance energy efficiency and indoor air quality. Knowledge of Air Sealing is used to improve thermal comfort, reduce energy consumption, and minimize the infiltration of outdoor pollutants by ensuring a more controlled indoor environment.

Blower Doors refer to a diagnostic tool used to measure the airtightness of buildings and identify air leakage points. This skill involves the use of a fan mounted in a door frame to create a pressure difference, allowing for the assessment of airflow and energy efficiency. Knowledge of Blower Doors is applied in building performance testing, energy audits, and compliance with energy codes, facilitating improvements in insulation and overall building envelope integrity.

Building performance is the practice of analyzing, evaluating, and optimizing the performance of buildings to ensure they operate efficiently and sustainably while providing healthy indoor environments. It involves a specialized set of skills, including knowledge of building systems, energy efficiency, environmental sustainability, and indoor air quality. Building performance professionals use a variety of tools and techniques to assess and improve building performance, such as energy audits, building modeling, and retrofitting. The goal is to create buildings that are both environmentally responsible and provide a high level of comfort and functionality to occupants.

Certified Energy Manager refers to the knowledge and methods used to assess, monitor, and improve energy use in buildings and industrial facilities. It is applied to identify efficiency opportunities, evaluate utility data, and support energy management plans that reduce waste and operating costs. The skill also supports compliance, reporting, and the implementation of energy saving measures across work settings.

Energy Efficiency Assessment refers to the systematic evaluation of energy use within a building or system to identify opportunities for reducing energy consumption and improving overall efficiency. This skill involves analyzing energy data, assessing equipment performance, and identifying areas where energy waste occurs. Knowledge of Energy Efficiency Assessment is used to develop strategies for implementing energy-saving measures, which can lead to cost reductions and enhanced sustainability in various environments.
