This book is the second edition of Numerical methods for diffusion phenomena in building physics: a practical introduction
originally published by PUCPRESS (2016). It intends to stimulate research in simulation of diffusion problems in building
physics, by providing an overview of mathematical models and numerical techniques such as the finite difference and finite-element
methods traditionally used in building simulation tools. Nonconventional methods such as reduced order models, boundary integral
approaches and spectral methods are presented, which might be considered in the next generation of building-energy-simulation
tools. In this reviewed edition, an innovative way to simulate energy and hydrothermal performance are presented, bringing
some light on innovative approaches in the field.
