This chapter provides an overview of fundamental concepts useful to carry out an energy analysis of both new and existing buildings. The energy analysis concepts outlined in this chapter is focused on modeling and evaluation of building envelope components and their impact on thermal loads for heating and cooling systems under steady-state and transient conditions. In particular, basic modeling methods and techniques are presented for building thermal analysis. These modeling methods are then applied to develop forward and inverse models and simulation tools used to design, operate, and retrofit building energy systems. Finally, some of the commonly utilized whole-building energy simulation tools and their applications are presented.
