What is the required U-value for opaque swinging doors installed in climate zone 3 for group R?

1. U-0.71

2. U-0.61

3. U-0.51

4. U-0.41

The correct answer is: U-0.61

The required U-value for opaque swinging doors installed in climate zone 3 for group R is specified in building energy efficiency codes to ensure that these doors provide a certain level of thermal performance. A U-value measures the rate of heat transfer through a building element; in this case, lower values indicate better insulating properties. For climate zone 3, the standards have established specific U-values for various building components to promote energy efficiency in residential buildings. The U-value of 0.61 for opaque swinging doors reflects an adequate balance of energy efficiency while allowing for practical construction and design considerations. It’s important to ensure that building materials meet these U-value requirements because they play a crucial role in reducing thermal loss, contributing to more energy-efficient buildings. Meeting or exceeding the required U-values helps to enhance indoor comfort and reduce heating and cooling costs for residents. In conclusion, the U-value of 0.61 is aligned with the criteria set forth for energy performance in climate zone 3 for group R, making it the correct choice for this question.
