Which credit focuses on ensuring that energy-efficient designs are integrated during construction?

The credit that focuses on ensuring that energy-efficient designs are integrated during construction is associated with Building Energy Performance. This credit emphasizes the importance of not just designing energy-efficient systems, but also implementing them during the construction phase to ensure that the performance expectations established during the design are met when the building is operational.

This integration during construction helps in achieving overall energy efficiency goals for the building, including maximizing energy savings, reducing greenhouse gas emissions, and improving overall indoor environmental quality. By focusing on performance metrics and real-world testing, this credit ensures that the energy-related features of a building operate as intended once the building is completed.

The other choices, while relevant to energy and sustainability, do not specifically address the integration of energy-efficient designs during the construction phase. The optimization credit tends to focus more broadly on energy modeling and potential savings, while Indoor Environmental Quality and Sustainable Sites target other aspects of building sustainability unrelated to energy efficiency during construction.
