The main benefit of the book is that it explores available methodologies for both conducting in‎-situ measurements and adequately exploring the results‎,‎ based on a case study that illustrates the benefits and difficulties of concurrent methodologies‎.‎ The case study corresponds to a set of 25 social housing dwellings where an extensive in situ measurement campaign was conducted‎.‎ The dwellings are located in the same quarter of a city‎.‎ Measurements included indoor temperature and relative humidity‎,‎ with continuous log in different rooms of each dwelling‎,‎ blower‎-door tests and complete outdoor conditions provided by a nearby weather station‎.‎ The book includes a variety of scientific and engineering disciplines‎,‎ such as building physics‎,‎ probability and statistics and civil engineering‎.‎ It presents a synthesis of the current state of knowledge for benefit of professional engineers and scientists‎.‎
