Cutting-edge building energy management systems (BEMS) interact with heating, ventilation, air conditioning (HVAC) systems, which generally account for much of the consumption. Major attention is focused on BEMS themselves, barring on-field equipment. In HVAC equipment, sub-optimal controller settings may lead to losses and user discomfort, instance, due oscillations temperature fan speeds. The...

1 At the time this work was performed, Maria Corsi was a Research and Development Agent at CANMET-Energy Technology Centre, Natural Resources Canada. ABSTRACT The evolving capabilities of Building Energy Management Systems (BEMS) offer new opportunities to automate some parts of the commissioning process and can generate benefits over the entire life of a building. These benefits include a redu...

BEMS (Building Energy Management System) and BACS Automation Control make available a high quantity of data on consumptions, indoor outdoor conditions users' profiles buildind that can drive the choice energy retrofit interventions. Moreover, current developments in digitalization building process, are leading diffusion BIM methods tools which provide valid support to manage all information for...

The analysis of damping phenomena that occur in many physics and engineering problems, such as fluid dynamics, kinetic theory and semiconductors, is of particular interest. For this kind of problems, one needs accurate and stable approximate solutions even on large time intervals. These latter can be obtained reformulating time-dependent problems modeled by partial differential equations (PDEs)...

Particle-based simulation represents a powerful approach to modeling physical systems in electronics, molecular biology, and chemical physics. Accounting for the interactions occurring among charged particles requires an accurate and efficient solution of Poisson's equation. For a system of discrete charges with inhomogeneous dielectrics, i.e., a system with discontinuities in the permittivity,...

A patch representation differing from the traditional treatments in the boundary element method (BEM) is presented, which we call the constant "node patch" method. Its application to solving the Poisson-Boltzmann equation (PBE) demonstrates considerable improvement in speed compared with the constant element and linear element methods. In addition, for the node-based BEMs, we propose an efficie...
