New Simulation Tool for Architectural Design in the Realm of Solar Radiative Transfer

Abstract

In this paper, we devise a system for architectural simulations that considers the volumetric and three-dimensional properties or the energy sources involved in the energy exchanges within or around edifices and built or urban spaces. The advances are based in optics theory evolving from the assumptions presented in the book The Photic Field by P. H. Moon and D. E. Spencer, with added improvements suggested by D. DiLaura. Such procedure is deftly performed by means of solving complex integral equations, which were unavailable until recently and originate in the research developed by the authors. This experimental software is called DianaX. The advantages of this new system allow for a clearer visualization of the performance of buildings in terms of radiated energy. Reductions in the amounts of used energy can be achieved precisely by means of the design process of the software, which can be considered in some respects as a Design Tool. With this tool, the analysis of heritage building paradigms is feasible as it assesses the potential of new foreseen projects taking into account new artificial lighting devices that deviate from the conventional linear or point approach in the domain. The main finding demonstrated is the feasibility and appropriateness of this method to address the problems posed. As future prospects, we would like to increase the catalogue of designs that can benefit from the conscious use of our tool for scientific design.

The Search for Solar Architecture in Asia in the Works of the Architect Antonin Raymond: A Protracted Balance between Culture and Nature

“…To demonstrate the effectiveness of Raymond's ideas, cast intuitively, we have simulated the solar trajectories (Figure 9) for this building to ascertain that the orientation and louver details calculated by means of the software developed by the authors [24] are well adapted to the site and the local climate. This building is still in perfect use after 85 years, it features a Japanese garden with a lantern, a pond, and some worship halls.…”

The behavior, recently checked with accurate monitoring by architect Mona Doctor-Pingel, seems adequate, since, in the particular case in which the system is set to a horizontal position, the increases in illuminance are relevant as compared with a normal window, which is hardly predictable without computer tools [25].…”

Sustainable Design in Building and Urban Environment

“…Cabeza-Lainez et al [3] introduced a system called DianaX for architectural simulations that considers volumetric and three-dimensional properties, as well as energy sources involved in energy exchanges within and around buildings and urban spaces. The system is based on advances in optics theory, building upon assumptions of different studies in this field.…”
