Previous studies have shown that indoor environmental quality (IEQ) parameters may a considerable effect on office employees’ comfort, health and performance. Therefore, we initiated research program to help occupants identify IEQ they perceive as risk factors for their in an enhance comfort levels environment. Since assumed employees might different expectations related work area these differe...

Abstract The market of smart building solutions aiming at improving the comfort, well-being and health occupants, but also inclusiveness accessibility to people with more specific needs is growing. More solutions, as well standards, certifications public regulations are currently being developed, a global systemic approach seems be missing. paper reviews status research related means methods en...

The occupants' presence, activities, and behaviour can significantly impact the building's performance energy efficiency. Currently, heating, ventilation, air-conditioning (HVAC) systems are often run based on assumed occupancy levels fixed schedules, or manually set by occupants their comfort needs. However, unpredictability variability of patterns lead to over/under conditioning space when us...

It is common to control several rooms in a building with a single sensor in one of the rooms and a single actuator driving just one control element such as an air damper. New, low-cost, wireless sensor technology now offers the opportunity to replace the single sensor in one room with a network of sensors where there is at least one sensor per room. This paper addresses this multi-sensor, singl...

In this paper, we propose a new HVAC (heating, ventilation, and air conditioning) control strategy as part of the smart energy system that can balance occupant comfort against building energy consumption using ubiquitous sensing and machine learning technology. We have developed ZigBee-based wireless sensor nodes and collected realistic temperature and humidity data during one month from a labo...

Occupant behavior has a significant impact on building energy performance. The purpose of this paper is to quantify the stochastic characteristics of manual solar shades and their influence on building energy performance. A co-simulation for occupants’ stochastic control of manual solar shades was conducted and the statistic indicators (non-parameter tests and autocorrelation function) were cal...

undoubtly it can be said that climate and how weather conditions effect on building shape including limited architecture elements which has been noticed at the beginning of making shelter by human beings and the principle of this need has not been changed by passing time and changing the styles and movements and definitions of art and beauty and changing needs and attitudes and expanding archit...

The phase change material (PCM) used in a building wall can reduce building energy consumption and improve the living comfort level. However, only when the temperature of the PCM layer is between phase transition temperature ranges can it have the maximum effect to increase the thermal inertia. How to select the suitable PCM according to the local weather and building wall always troubles build...

Ensuring thermal comfort is an important goal in the operation of any office building. Often these buildings are therefore controlled according to the predicted mean vote (PMV) model which is also adopted as the ISO 7730 norm. This model predicts the mean thermal preferences of an average group of people that would satisfy the thermal comfort needs of about 80% of the occupants. It is derived f...

Despite the fact that buildings are designed to meet occupants' needs, many do not perform as planned, impacting upon both building performance and comfort. Analyzing comfort based on questionnaire surveys requires specific information appropriate use of visualization techniques identify possible dissatisfactory problems. However, existing studies provide a user-friendly interoperable with Buil...
