Item description for Introduction to Building Physics by Carl-Eric Hagentoft...
The state and operation of the building envelope--walls, roofs and foundation--are analyzed as well as the physical process components: heat, moisture and air transfer. These physical transport processes determine the performance of the building. Thorough knowledge of building physics is essential for planning and constructing sound,energy-efficient buildings with high levels of comfort and durability. This book will help the reader anticipate the performance and consequences of alternate designs as well as determining technical solutions before critical design and construction decisions can be made. The focus of this text is on the theories behind the physical problems which may arise and offers mathematical models to arrive at needed solutions.

Good practical book Aug 6, 2009
This book ia aimed at the practitioner who has a penchant for mathematics. It is mainly centered around heat and mass transfer. There is no structural mechanics here. The reader is supposed to have already followed an introduction to thermodynamics and of course some vector calculus, but there is a quick refresher for the calculus in an appendix. I was hoping the book would shed some light on why thermal bridges exist but I was disappointed. This book is light on the derivation of the physiscs from first principles, it's more of the kind, "Here are the equations, now we shall turn you into a problem solver by giving you worked examples".
Since at the time of writing there is no way you can "look inside" this book, I have copied the table of contents for you:
