Abstract:
Centralized air conditioning systems are widely used in buildings at present. In these conditioners, the outside air gets required temperature, humidity, purity, and other features, necessary for creating comfort microclimate in inside areas of houses, and by the help of fans and air ducts the processed air moves to all rooms of a building. As a result, the creation and maintenance of comfort conditions in buildings become complicated and expensive activity. From this point of view, it is becoming more expedient to install local air conditioners in each room instead of single central one for t

Abstract:
Demand-driven heating, ventilation, and air conditioning (HVAC) operations have become very attractive in energy-efficient smart buildings. Demand-oriented HVAC control largely relies on accurate detection of building occupancy levels and locations. So far, existing building occupancy detection methods have their disadvantages, and cannot fully meet the expected performance. To address this challenge, this paper proposes a visual recognition method based on convolutional neural networks (CNN), which can intelligently interpret visual contents of surveillance cameras to identify the number of o

Abstract:
The odor generated by air conditioners is an important factor influencing the perceived air quality in buildings. In this study, different types of air conditioners and air filters were investigated to study the level of odor emission related to the operation state of the compressor, to identify the odor compounds and to analyze the cooling setpoint temperature on emitted odor intensity. Results show that the odor from constant frequency air conditioner use is periodic and stronger than that from variable frequency air conditioner use due to the different operation strategies of the compressor

After setting target electricity consumption, the algorithm is applied as a method of updating target electricity consumption.

This paper presents IoH (Intelligence of Home), a platform developed to test some basic intelligent behaviors in Home context. Internet of Things, ambient intelligence and context awareness approaches motivated the development of IoH. The platform involves six layers, responsible by connectivity, persistency, unification, Internet of Things integration, subsystems integration and user interface. The integrated subsystems involve intelligent systems for light control, television brightness control, desk light control, persons counting and air conditioner control. The IoH platform is then tested

Abstract:
Electrical and energy production have a noticeable water footprint, and buildings′ share of global energy consumption is about 40%. This study presents a comprehensive experimental analysis of different thermal impacts and water consumption of green roofs in a Mediterranean climate. The study aims to investigate the use of water directly for green roofs and reduce the water footprint of energy in summer and winter due to its thermal impacts. The measurements were carried out for an extensive green roof with an area of 55 m2 and a thickness of 22 cm, and direct water consumption by a green roof

Abstract:
Most of the appliances used in office buildings such as the room lights, fans and Air Conditioners (AC) are manually operated, where one has to switch ON and OFF these appliances. If one tends to forget to turn OFF these switches, it will impose a major challenge in building economic stimulus for their fiscal development. It can thereby increase the amount of energy consumed and thus increasing the electricity bills. Therefore, there is an urgent need for improvement and use of a smart lighting system.

This research studies about the possibility of Phase change materials for development with the double roof system which uses the Radiant barrier to reduce the heat into the house and to reduce load of the air conditioner. The experiment was divided into 4 patterns. The Radiant barrier and the Phase change materials are on top of the air passage (model 1). The Phase change materials and the Radiant barrier are on top of the air passage (model 2). The Radiant barrier is under the roof and the Phase change materials is under the air passage is (model 3).

Abstract In dense mega cities, high-rise buildings huge energy consumption on mechanical ventilation and overheat produced by the air conditioners are among big challenges for the sustainable building development and green city construction. Solar chimney is proved to be an efficient method to promote natural ventilation for buildings. Different types of solar chimney are presented with a high-rise building layout example. Solar chimney geometry and environment basic data is suggested to be evaluated to optimize the Solar chimney’s natural ventilation. In addition, aiming as well a clean and s

The cooled air is supplied to the building with the help of ducts. When ducts are not properly designed, then it will lead to problem such as frictional loss, higher installation cost, increased noise and power consumption. For minimizing this problem, a prop

Abstract:
Installation of insulation materials in buildings can reduce the usage of air conditioners by retarding heat flow into the building. Aerogel is one of the best insulation materials with distinctive properties that can replace existing building insulation materials such as fibre glass and polyurethane. However, brittleness of Aerogel makes it difficult to handle and disqualifies its viability as a building insulation material. Reinforcement of Aerogel with binding materials can improve its mechanical and thermal properties to overcome its brittleness. However, only a few studies have been carri
