In the context of energy consumption reduction, this paper focuses on the application of Model Predictive Control to occupants’ thermal comfort together with indoor air quality control while improving the whole building energy efficiency. First, an open-space office split in three zones, located in Cork Institute of Technology, is modeled. A centralized MPC is designed to control the temperatur...

Abstract In a built space, the visual comfort is an important factor. It depends on exterior environmental conditions. general, daylight has positive effect human behaviours and circadian rhythm. Also, occupants with great connect outdoors achieve high productivity. The tend to use shading devices based local conditions not future weather this background, kinetic facades provide higher degree o...

UNLABELLED Building occupants are a rich source of information about indoor environmental quality and its effect on comfort and productivity. The Center for the Built Environment has developed a Web-based survey and accompanying online reporting tools to quickly and inexpensively gather, process and present this information. The core questions assess occupant satisfaction with the following IEQ...

Thermostats are primary interfaces for occupants of office buildings to express their comfort preferences. However, standard thermostats are often ineffective due to inaccessibility, lack of information, or limited responsiveness, leading to occupant discomfort. Software thermostats based on web or smartphone applications provide alternative interfaces to occupants with minimal deployment cost....

Abstract The influence of people on building performance is becoming increasingly significant. Including users’ perspective in decision-making and design processes could help to improve occupants’ well-being the feasibility interventions by providing more accurate information about heating preferences for energy models. Furthermore, understanding residents’ level thermal satisfaction enable app...

This paper presents results of over 34,000 survey responses to air quality and thermal comfort questions in 215 buildings in US, Canada, and Finland. Results show that 80% or more of the occupants expressed satisfaction with their thermal comfort in only 11% of the buildings surveyed. Air quality scores were somewhat higher, with 26% of buildings having 80% or occupant satisfaction. With respec...

Commercial buildings often experience faults that produce undesirable behavior in building systems. Building faults waste energy, decrease occupants’ comfort, and increase operating costs. Automated fault detection and diagnosis (FDD) tools for buildings help building owners discover and identify the root causes of faults in building systems, equipment, and controls. Proper implementation of FD...

Abstract 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. In desert countries this aim is more difficult to achieve since high ambient air temperatures create a barrier to comfort. Traditional building types of these countries, such as courtyard building, have evolved t...

Building Automation Systems control HVAC systems aiming at optimizing energy efficiency and comfort. However, these systems use pre-set configurations, which usually do not correspond to occupants’ preferences. Although existing systems take into account the number of occupants and the energy consumption, individual occupant preferences are disregarded. Indeed, there is no way for occupants to ...
