from building design point of view a basic aim of low energy architecture is to create a thermally comfortable internal environment for building occupants whilst consuming the least possible amount of energy. thus, thermal comfort study has an important impact on energy saving. achieving comfort conditions requires an understanding of the interaction between three groups of factors, namely phys...

The theme of this paper is the design of an intelligent coordinator (IC) of fuzzy controller-agents (FCAs) to control indoor environmental conditions in buildings by using a 3-D fuzzy comfort set. The basic factors that participate in the control of indoor environmental conditions are the controllers and users’ comfort requirements. Harmonization of these factors results in energy saving, and o...

The problem of controlling a heating ventilating and air conditioning system in a single zone of a building is addressed. Its formulation is done in order to maintain acceptable thermal comfort for the occupants and to spend the least possible energy to achieve that. In most operating conditions these are conflicting goals, which require some sort of optimisation method to find appropriate solu...

Heating Ventilation Air Condition (HVAC) systems consume the majority of energy in a building; it is essential to optimize this while improving thermal comfort occupants. The Predict Mean Vote (PMV) model considered as one most efficient models define structure. In context paper proposes prediction PMV index using ANN algorithm classify real-time states occupants, which may provide future savin...

Thermal mass is the material's ability to store heat and release it after an amount of time and concrete is considered one of the best thermal mass material. Since concrete has been used widely in many building constructions, by considering the capability of concrete in terms of thermal mass, it is worthwhile to use this ability of concrete in order to build buildings more healthy and comfortab...

This paper deals with the issue of achieving comfort in buildings with minimal energy consumption. Specifically a reinforcement learning controller is developed and simulated using the Matlab/Simulink environment. The reinforcement learning signal used is a function of the thermal comfort of the building occupants, the indoor air quality and the energy consumption. This controller is then compa...

Solar passive techniques are being used in vernacular buildings throughout the world. Researchers have done extensive study on thermal performance of vernacular buildings in the different parts of the world. Vernacular architecture of North-Eastern India represents the principle of climate-responsive architecture, which still lacks experimental validation and quantitative analysis. Thermal comf...

When talking about energy efficiency at global scale, buildings are the cornerstone in terms of power consumption and CO2 emissions. New communication paradigms, such as Internet of Things, can improve the way sensors and actuators are accessed in smart buildings. Following this approach, we present an energy efficiency subsystem integrated with a building automation solution that makes the mos...

Vegetation moderates a microclimate by casting shadows, increasing light reflection, evaporation and perspiration; and correcting wind patterns. The present study aims to investigate the microclimatic role of vegetated surfaces and bodies in improving thermal comfort in outdoor spaces between buildings. The main research question is which of the green system modes, that is, horizontal vegetatio...

In this work we propose a framework for incorporating occupant feedback towards temperature control of multi-occupant spaces, and analyze it using singular perturbation theory. Such a system would typically have to accommodate occupants with different temperature preferences, and incorporate that with thermal correlation among multiple zones to obtain optimal control for minimization of occupan...
