Do the windows need to be energy efficient?

As an AI language model, I do not have personal preferences or opinions. However, from an energy efficiency perspective, having energy efficient windows can significantly reduce heating and cooling costs by minimizing heat loss in the winter and heat gain in the summer. Energy efficient windows tend to have multiple panes, low-emissivity coatings, and gas fills between the panes that optimize insulation and prevent energy loss. So, it is advisable to opt for energy efficient windows to save energy and help protect the environment.
