The aim of this research is to assist the consumer to control the air conditioning load during the peak season. Demand side response model was applied to manage inside room temperature to keep comfortable for the consumer. A simulation study is illustrated the effect of demand side response model application for air conditioning in residential house in Makassar city. In this research there are three...
This work presents preliminary observations of the first lightning flash striking an instrumented lightning rod on the top of a common building in Brazil. The measurements include direct electric current in the lightning rod, high-speed recordings using different types of cameras and data from two lightning location systems (LLS) that operate in Brazil: RINDAT and BrasilDAT. The striking flash contained...
Humans live and spent their times in buildings. Determining the best configuration for their office or apartment (HVAC configuration, doors and windows positions, usage of appliances, …) is becoming subtle because low consumption buildings are becoming more and more sensitive to human behavior. Moreover, variable energy costs and energy availability issues increase the complexity of the energy management...
This paper proposes a novel occlusion detection method for urban true orthophoto generation. In this new method, occlusion detection is performed using a ghost image; this method is therefore considerably different from the traditional Z-buffer method, in which occlusion detection is performed during the generation of a true orthophoto (to avoid ghost image occurrence). In the proposed method, a model...
GBAS is the next generation navigation system for aircraft landing using GPS, and is being developed. VDB of GBAS ground subsystem is utilized to send correction information for positioning and integrity monitoring of GPS. VDB coverage is required not only in the air but also above runways to support an auto-land and a roll-out. This paper clarified the effect of buildings on VHF propagation in the...
This paper proposes a new method of occlusion detection to generate true orthophotos. This method describes the geometric relationship between occlusion area and ghost image by establishing a mathematical model. The advantage of this method is: (1) the model we have established indicates that sizes and boundaries of occlusion areas can be determined by buildings' roofs and visual facades. We take...
LIDAR (Light Detection and Ranging) is an especially effective tool for acquiring geo-referenced point clouds of urban site. Accurate extraction of elevated features such as building rooftops is vitally important in various applications. However, it is still challenging to determine an accurate rooftop contour from the irregularly distributed LIDAR point clouds. In this paper an efficient LIDAR segmentation...
Traditional ortho-rectification is the most commonly method, which used to rectify the deformation caused by center-projection. However, the occlusion caused by high buildings could not be recognized by computer in the process of traditional ortho-rectification, and the double-mapping is raised. This is the so-called “ghost image”. In order to eliminating double-mapping and detecting occlusion, this...
This paper represents the feasibility study and analysis of a grid-connected hybrid (PV-Wind) system with battery, realized within the project DE.DU.ENER.T and installed in the research centre CRTEn located in the northern Tunisia in the city of Borj-Cedria. The main objective of this work is to exploit renewable sources of electrical energy production to electrify the desired building. So, to minimize...
The energy consumed by buildings is the most important component of the total energy consumption in the developed countries, but also worldwide. There are several important international programs which aim at developing innovative ways for reducing the consumption of energy related with buildings. Producing and consuming locally the energy is the most effective way of harnessing the maximum benefit...
Nowdays, airborne LiDAR comes into a popular way to survey the ground scene, particularly for the application of building reconstruction. However, the LiDAR point cloud acquired is usually polluted by noise for the existence of LiDAR system's inherent error and aircraft's shock. Thus, before LiDAR data is used, a preprocessing such as denoising is needed. This paper focus on the denoising of building...
With the consequences of urbanization trends and climate changes, the impacts and interactions of flood disasters have become significantly complicated. As a complex system engineering, flood disaster risk assessment takes on very important meaning in the theory and practice of flood control. Flood disaster risk is the consequence of the interactions between different factors in a complicated flood...
The current attention to energy management leads to the necessity to tack new challenges for a best integration of renewable energies, mobility systems and new technologies for the energy efficiency, creating several micro grids with an active interaction with the main energy distribution networks. The integration of more energy systems seems to be the key of the future development and at present...
It is sometimes necessary to reduce the electromagnetic signature of buildings because of their undesirable effect on aircraft navigation systems. Indeed, planning permission is not granted to buildings close to airport runways unless their perturbation can be reduced to less than specified regulatory thresholds. This paper presents two solutions for doing this: A thick, conventional, diffraction...
The ARTEMIS 1 project DEWI ("Dependable Embedded Wireless Infrastructure") focusses on the area of wireless sensor / actuator networks and wireless communication. With its four industrial domains (Aeronautics, Automotive, Rail, and Building) and 21 clearly industry-driven use cases / applications, DEWI will provide and demonstrate key solutions for wireless seamless connectivity and interoperability...
In this paper, we focus on the prediction method of building energy consumption time series. The building energy consumption data can be regarded as a time series, which is usually nonlinear and non-stationary. Traditional time series analysis model has lower prediction accuracy. Then the machine learning method, especially support vector regression algorithm always has better performance to deal...
Energy-autonomous buildings in off-grid areas have to minimise the operational cost while not sacrificing the occupants' comfort levels. At the generation side, such buildings increasingly consider hybridising traditional and renewable generators, using a battery energy storage system as back-up and for operational optimisation. At the demand side, energy management is applied to satisfy the multiple...
Texture segmentation is a critical step in building-based analysis in urban remote sensing images to obtain more detail information for further applications. Most existing segmentation algorithms rely on region or edge information to segment, which failed to segment building surfaces with almost same texture and unclear edge between the surfaces. Therefore, in order to solve this challenging task,...
This paper describes a software for creating models of energy flow and calculation the heating plan with use of the air/water heat pump.

The software can be also used for exact heat pump design for the specific building. With appropriate plan, which the article deals...
The application of automation technology in the management of electrical energy is intended to limit the use of electrical energy in a building in order to avoid wasting energy sources and for easy monitoring and controlling a system. A Supervisory Control and Data Acquisition system provide some important information related to the use of electrical energy in a building. All information is urgently...
