This research would be the early stage in saving and managing energy, especially electrical energy in a miniature. The research has been done in the assembly of components, namely temperature, humidity, lighting and electric active power sensors, where they were equipped by 4–20 mA transmitters. These transmitters entered to the four channel analog module of programmable logic controller (PLC). From...
The paper addresses the problem of efficiently monitoring environmental fields in a smart building by the use of a network of wireless noisy sensors that take discretely-predefined measurements at their locations through time. It is proposed that the indoor environmental fields are statistically modeled by spatio-temporal non-parametric Gaussian processes. The proposed models are able to effectively...
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...
In this work, we propose the development of monitoring system for the Air Handling Unit of a particular building of the University via Zigbee network. The proposed system will provide all the essential information required for the thermal modeling of the building using Dynamic Thermal Simulation. Furthermore, this will allow us to accomplish autonomous building management and also to study the thermal...
LepidaSpa, the in house company of all the Public Administrations of Emilia-Romagna region, successfully led a feasibility analysis for the creation of a sensors network to monitor the energy consumption in public buildings to support actions towards energetic saving. The innovative aspects of the solution adopted mainly concern the extreme simplicity of the network architecture used, the ease of...
Nowadays, building performance are mainly focused on energy efficiency and indoor environmental quality because (i) buildings are responsible of about 40% of the energy consumption at European level, and (ii) people spend more and more time in indoor places, whose comfort has strong influence on health, behavior, and working efficiency. This paper proposes an innovative strategy for the estimation...
Air-conditioning systems consume between 40 and 50% of the total energy consumption in buildings in Singapore. Set-point scheduling in existing office buildings is challenging as it is necessary to maximize energy savings without causing thermal discomfort to the occupants that can lead to a reduction in productivity. Thermal comfort depends on environmental factors such as air temperature, humidity,...
Steadily raising standards for indoor environmental quality in living and office spaces lead to an extensive utilization of high performance and power-demanding climate control systems. An increasing utility and energy cost for buildings operation, in turn, pushes researchers and manufactures to explore new strategies to reduce energy waste and minimize ecological impact. The key enabler for an efficient...
Wireless Sensor Networks (WSN) are a versatile technology that offers the ability to monitor real-world phenomena in detail and at large scale in scenarios where wired infrastructures are inapplicable or expensive. In this paper we present an ad-hoc WSN deployment for indoor environmental quality monitoring in office buildings. The indoor environmental quality and balance between inhabitant comfort...
Indoor air quality (IAQ) is a term that describes the air quality of the building occupants. IAQ can be influenced by physical factors like dust particles, chemical or gaseous pollutants (including carbon dioxide, carbon monoxide and volatile organic compounds) and biological factors like molds and bacteria growth which largely depend on temperature and humidity condition of a room. These kinds of...
The traditional fire monitoring system for historical building adopts wired mode which can do a lot of damage to the building. In order to solve this problem, a wireless fire monitoring system is designed based on the CC2530. The sensor node and the routing strategy are implemented in this system. The sensor nodes sense the temperature, light and smoke. Then they transmit this information to the coordinator...
Monitoring the structural health and the local climate of historical heritage buildings may be a hard task for civil engineers for assessing the energy efficiency of the environment, due to the lack of a pre-existing monitoring model, and due to the presence of deployments with strict installation constraints. This paper reports on the experience gathered during an European Project (3ENCULT Project...
When utilized properly, energy management systems (EMS) can offer significant energy savings by optimizing the efficiency of heating, ventilation, and air-conditioning (HVAC) systems. However, difficulty often arises due to the constraints imposed by the need to maintain an acceptable level of comfort for a building's occupants. This challenge is compounded by the fact that human comfort is difficult...
Sensor network research is a large and growing area of academic effort, examining technological and deployment issues in the area of environmental monitoring. These technologies are used by environmental engineers and scientists to monitor a multiplicity of environments and services, and, specific to this paper, energy and water supplied to the built environment. Although the technology is developed...
Energy, both in terms of its production and its usage has occupied a prime place in research as well as politics and world economy for the past few years. The majority of nations are aiming to deliver severe carbon cuts in the next few years. However, achieving a carbon-free future needs more than infrastructure investment and novel efficient technologies for buildings, transportation and other large...
The viability of wireless sensor applications often hinges on minimising power consumption whilst maximising the informational output. Although many low-level platform-oriented energy saving mechanisms have been developed, considerable savings are possible at application level. This work presents an approach to pushing the calculation of application-level state closer to the information source. The...
This paper proposes the idea of a wireless sensor network with applicability in monitoring systems.

The obtained data is processed by a Decision Support System, which (1) calculates the current...
Air conditioners possess a large proportion of the energy consumption in a building for both heating and cooling functions. The purpose of this paper is to present the work in progress which uses simple and cheap sensor nodes mounting on the external unit of air conditioners to automatically sense the usage pattern. This work is part of the project called Cyber IVY, which provides means of building...
Increasing awareness of energy production evolution and global warming issues have forced regulatory international organizations to supervise energy consumption in different areas. Specifically the energy efficient operation of buildings, consumers of almost a third of the energy produced globally, is to be evaluated by means of specific procedures. The usual methods involve the use of normalized...
