This paper aims to find out the level of awareness among Islamabad residents regarding energy efficient buildings. Furthermore, like other important variables such as income level, age, education level, status, price of such buildings, etc. influence this level of awareness. Awareness is defined as the level of attention. Several countries have been studied for this purpose. A brief overview of similar studies is provided below. A study conducted in Sweden showed that the two methods to save energy are measuring investments and changing behavior. The first method aims at the fact that buyers who have more accurate, complete, relevant and easily accessible information on energy efficient buildings would be in a better position to make an effective purchasing decision. However, in the second method, human behavior and actions related to energy saving are targeted. They are informed so that they feel motivated to use these energy-efficient methods in their practical life for the green environment for a longer period. This information is provided to users through various Swedish and European organizations and government authorities. One of them is “The Swedish National Energy Administration”. STEM is an energy consultant that operates on the idea that environmentally friendly products such as appliances, windows, heat pumps and control systems are only consumed if buyers have access to the right and relevant information. The availability, affordability and energy consumption of such products must be labeled on them. Consumers must be informed about the actual results of eco-friendly products through sources such as the mass media, local fairs, the internet such as social media and direct communication with the...... medium of paper..... . indicate that this competition increased the level of awareness of the village residents only because they also have some prior knowledge. This suggests that there is a positive and significant relationship between the two variables. The results showed that changes in people's energy efficiency can be explained more in terms of a constructivist view than a behaviorist view. Whatever knowledge they have about energy efficient buildings and energy conservation, it is learned primarily from their personal experiences. It is proven that friends and media are the key sources for obtaining information. Therefore, to increase their awareness, it is important that related information is present to them in a natural way. Energy efficient products should be readily available. Such products should be highly marketed to attract the buyer's attention.
