Which entity provides guidelines on energy efficiency for residential projects in Alaska?

The correct answer is that the Alaska Energy Code provides guidelines on energy efficiency for residential projects in Alaska. This code is a set of regulations designed to promote energy conservation and efficiency in building design and construction. It outlines specific requirements for various aspects of residential buildings, including insulation, heating and cooling systems, water heating, and overall energy usage.

The Alaska Energy Code is crucial because it helps ensure that homes in the state are built to minimize energy consumption and reduce environmental impact, addressing the unique challenges posed by Alaska's climate. By adhering to these guidelines, builders and contractors can improve energy efficiency, which can lead to lower utility bills for homeowners and contribute to sustainable building practices.

While the other options may address aspects related to construction, housing, or the environment, they do not specifically focus on energy efficiency guidelines in the same comprehensive way that the Alaska Energy Code does. For instance, the Alaska Building Association may advocate for building best practices, the Department of Environmental Conservation may regulate broader environmental issues, and the Alaska Housing Finance Corporation might focus on housing finance and assistance rather than explicitly on energy efficiency regulations.
