This paper presents an overview of the Integration and Intelligence for Sustainability concept or better called I2S. The system will be installed in the Campos dos Goytacazes Innovation Hub (PICG) campus of the Instituto Federal Fluminense, and the project aims to integrate the data generated from different subsystems, mainly the renewable energy generation system, energy consumption, water treatment...
The paper proposes a sensorization plan for monitoring a relevant architectural case study at the University of Cagliari, in order to verify indoor thermo-hygrometric conditions and define a set of interventions which should be compatible with building preservation issue and oriented at improving its energy performance. The research aims at understanding how to organize and structure the compliance...
This paper develops a Net Zero Energy Building (NZEB) prototype with renewable energy integration applications. Most of the power generated by the utilities is consumed by the domestic loads and with urbanization; energy demand is continuously increasing in developing countries like India. To meet the ever growing demand, generation has to be increased and thereby transmitted over long distances which...
The critical requirements for devices connected in Internet of Things (IoT) are long battery life, long coverage range, and low deployment cost. In our previous work, we developed cognitive controller for controlling the HVAC of non-domestic building using short range communication in an unlicensed spectrum (915 MHz). In this work, we have upgraded our cognitive controller with recently developed...
The dense instrumentation of future smart buildings enables the implementation of advanced control techniques which are aimed at the dual objectives of energy efficiency/cost savings and occupant comfort. One of the essential functions and prerequisite consists of robust dynamic occupancy detection and prediction which allows improved estimation of active thermal zones and internal loads, as compared...
This paper summarizes the work performed by the authors on development of the sensor network for thermal parameters measurements, as well as structure health monitoring in modern buildings. The described work was carried out as a part of a workpackage within the EC FP7 project SESBE.
When hazardous events occurs in buildings or in large environments with different access points and with a large number of users, rescue workers (firefighters, first aid workers, civil protection teams, etc.) need to intervene in a timely manner, where there is a certainty that there are users to help. Topically such events require avoiding waste of resources in environments where there are no people...
This paper presents the usage of Internet of Things concept as a tool for retrofitting air conditioning systems. The proposed technology consists in an embedded system developed with an open-source hardware platform and connected through a wireless sensor and actuator mesh network. By learning commands from the air conditioner's remote control, the system is capable of implementing automatic control...
Buildings became complex systems where there are various technologies integrated together and thus should work as a single system. Modern building has several monitoring and control systems which should cooperate together to achieve energy saving while keeping indoor comfort and healthy environment. The overall building management systems (BMS) provides an integrated way to gather data from the building...
Heating, ventilation, and air conditioning (HVAC) systems can consume a large percentage of the energy used in a typical building. Intelligent building automation systems (BAS) are widely deployed to enable more efficient HVAC utilization, thus reducing the energy consumed. Enhanced data requires distributed sensing. We propose an instrumentation system for a low-cost, over-the-top efficiency monitor...
This paper focuses on the design of zero energy consumption for small building system that can support the government energy efficiency plan (EEP 2015). The design suits for small residential home in Bangkok that the energy consumption is up to 1,500 Wh/day. This paper designs the off-grid photovoltaic (PV) system which its structure consists of 3 main parts: generation, storage, and load. Experimental...
Considerable energy savings can be achieved through intelligent buildings that monitor the heating, ventilation and air conditioning systems that contribute a large proportion of energy consumption, particularly in extremely hot or cold climates. While intelligent building research focusses on automatically controlling such systems to maximise efficiency, there is a need for user input due to the...
The general trend in building commissioning is that the commissioning is often either insufficiently comprehensive in its execution, or it is not conducted at all. As such, it has been observed that buildings often will contain faults that have not been discovered during the commissioning phase. In this paper, we present a framework for continuous verification and commissioning of a building with...
The Internet-of-Things paradigm has brought exciting opportunities to increase productivity and efficiency but also customer experiences. Thus, IoT promoted both the interconnectivity of devices and systems but also their cloud connectivity. However, such plethora of connected things capture part of the contextual information in different data models which makes them operate in silos. We depict in...
The Network Controlled Distributed Energy Management System (NCDEMS) has been designed in compliance with IEEE 21451 standards. The developed system is capable of improving the power quality, efficiency of distributed energy resources, and power distribution for smart cities. The voltage and current sensors modules are implemented successfully. The Graphical User Interface (GUI) Apps of local and...
An efficient people occupancy detection, tracking, and behavior recognition method is introduced in this study. The problem of monitoring wide field can be achieved using the programmable camera network instated of the typical fixed cameras. In addition, based on the depth image feature, the shape feature of the occupant can be used to the activity recognition more accurately.
Wireless sensor networks are a cheap and versatile solution for monitoring various environments. There are a number of such applications used worldwide to monitor areas in which human access is hard or near impossible. These applications are mainly used by government organizations or for research purposes, while standardized or commercial applications are still under development. They seldom focus...
Optimal operation of heating, ventilation, and air conditioning (HVAC) systems can benefit from proper monitoring of the flows in the air ducts and water pipes. For large installations, this requires a large number of networked, Internet of Things (IoT) inspired sensors performing coordinated data acquisition. Cost-effectiveness and robustness are major issues for the design of such sensors. This...
Reducing energy consumption within buildings has become a focus of researchers. This paper looks modern buildings as a cyber-physical energy system and provide a three-layer architecture with the focus on energy saving. We introduce the key technologies from sensing, computation and controlling aspects, besides with highlighting some issues for consideration.
The heating, ventilation, and air conditioning (HVAC) system is designed to provide thermal comfort and acceptable indoor air quality. A variety of sensing devices (such as temperature, humidity, velocity, or pressure sensors) are installed in the HVAC systems. In a realistic situation, the HVAC system can fail to satisfy performance expectations envisioned because of a variety of problems. This paper...
