“…Undertaken tests with these configurations are, for example, studies on effects of new materials and new designed elements in building envelopes [113], or studies on peculiarities of the micro-climate in building site [17]. These tests are sometimes prerequisite for the accomplishment of the final construction.…”

a b s t r a c tA complete review on scale model testing for buildings, considering a wide range of methodologies and new manufacturing techniques, in areas such as statics and dynamics, acoustics, lighting, aerodynamics and thermodynamics for energy efficiency is presented. On the one hand, scale model testing for buildings require different considerations and techniques and are usually focused on one specific physical field contributing to the information scattering. On the other hand, they are sometimes too general, theoretical or unpractical. Although commercial computer simulations are first option among professionals, they necessarily simplify complex phenomena and ignore, among other aspects, size effects and latest findings in fractals. The potential of complementary experiments using new manufactured scale models for buildings is raising, however, it is still missing a practical overview through different physical fields specifically for buildings with these considerations. This review gives a wide perspective and unified scope on uses and possibilities of scale model testing for buildings, from the traditional configurations of Leon Battiste Alberti to new possibilities applying complex physics and new techniques of 3D-modelling.

“…The applications of the g factor and the U value are numerous. As an example, Bansalhail et al (1996) used them to size the various passive heating concepts for maintaining a set point temperature in a single zone building for various climatic conditions. Besides, the g factor can be used in design, for instance, Kontoleon (2015) analysed the optimum glazing in terms of orientation and placement in order to maximize the solar heat gain.…”

Water flow glazings include a water flowing chamber which enhances their thermal behaviour. This work addresses the connection between the optical properties and the energy performance of this type of glazings. The spectral properties of each layer of the glazing determine the fraction of solar radiation absorbed in each layer, which is later transported by the water in a closed circuit. The methodology requires the optical properties retrieved from the spectral problem and the thermal behaviour is predicted following the classical double glass pane analysis detailed in EN 673 (2011) and EN 410 (2011). The g factor and the U value of this new active glazing are obtained by solving analytically this model. Besides, it is shown that a third parameter, which takes into account the temperature of the inlet water, appears to complete the thermal behaviour of the glazing. In particular, three different configurations are examined. A comparison between these configurations is conducted and the active behaviour of the glazings is explained by means of a variable g factor which depends on the flow rate of the water chamber. The discussion includes some examples for the model parameters. The possibility to control dynamically the g factor provides huge energy saving potentials.
