Abstract: We present a simple sequential data protocol (SSDP) - an implementation of a lightweight message encoding and exchange protocol for Arduino-based sensor devices. The protocol supports simple data types, strings and binary arrays with low overhead. It defines several types of messages used to discover device metadata, send and receive sensor reading values and runtime parameter values, as well as alarms. The SSDP Arduino library is simple and has a low memory footprint. In conjunction with mesh networking, SSDP can be used to quickly and efficiently build sensor networks based on inexpensive Arduino hardware.

Abstract: In this work the application of a building dynamic simulation in the development of horizontal shading device passive solution applied in an university canteen is studied. The building dynamic simulation, that simulates simultaneously buildings or groups of buildings, with complex topologies, in transient conditions, considers the solar radiation, the HVAC system, glass radiative proprieties, radiative heat exchanges, thermal solutions, occupants’ comfort and air quality, and others. In the horizontal shading devices passive solutions the numerical model, using a sun trajectory and window position, developed efficient external shading devices. The canteen considers three levels and is divided in 37 spaces. In the simulation, 100 transparent surfaces and 773 opaque surfaces are considered. Special attention is given in the students’ main canteen, professors’ main canteen and university bar. The simulation is made in summer conditions. A simulation without and with horizontal shadi
