There is a worldwide growing demand for underground living due to increasing information about high energy efficiency of underground buildings. Why can't we design underground buildings for living? This question can be made for each person when he or she informs about advantages of underground construction.This paper will inform readers about influence of underground construction on energy efficiency of building and human comfort. Also it will bring together a new era of thinking about living underground as well as improving the learning experience. The paper will include a consideration of aspects which shape the decision making process, issues which conflict with underground buildings, opportunities to use past and current technology to create an external environment perception and a discussion to articulate the possibilities of occupying long term underground buildings.Key subjects to be discussed will include, but will not limit to: natural lighting, thermal comfort, indoor environmental quality, architectural issues and in general, energy dilemmas and solutions in underground buildings.
