The objective of this study is to determine the most energy efficient and cost effective combination of architectural elements and mechanical systems to specify in an office building while maintaining a comfortable and healthy indoor environment for the occupants. A commercial office building located in the Minneapolis area with three heating, ventilating, and air-conditioning (HVAC) systems an...

The paper aims to investigate different measures of passive cooling that are compatible with existing buildings in order to reduce the energy consumption and peak demand associated with the cooling. Both the existing conditions and envisaged thermal comfort preference of the occupants of the building determine which retrofitting technology is most suitable in a particular case. Measures focusin...

due to the increasing development in various branches of the automotive industry, the need for a comfort climate in the cabin is more sensible. however, to achieve climate comfort, hvac system consumes a considerable amount of engine power. hence, improving hvac system performance leads to more energy saving of the vehicle which is a critical factor for nowadays automotive. besides, one crucial...

Abstract—Buildings with shared spaces such as corporate office buildings, university dorms, etc. are occupied by multiple occupants who typically have different temperature preferences. Attaining a common temperature set-point that is agreeable to all users (occupants) in such a multi-occupant space is a challenging problem. Furthermore, the ideal temperature set-point should optimally trade of...

Energy information systems (real-time acquisition, analysis, and presentation of information from energy end-uses) in commercial buildings have demonstrated value as tools for improving energy efficiency and thermal comfort. These improvements include characterization through benchmarking, identification of retrofit opportunities, anomaly detection to inform retrocommissioning, and feedback to ...

The aim of using electromechanical air conditioning in buildings is to maintain thermal comfort for its occupants; however, this type represents 40% the total energy consumption a building, generating economic and environmental impacts, because fossil fuels are main source energy. To reduce use conditioning, it possible take advantage climatic conditions region improve performance. Due small nu...

Decarbonizing heating in buildings is a key part of climate change mitigation policies, but deep retrofit progressing slowly, e.g., at pace 0.2%/y the building stock Europe. By means tests two flats multiapartment housing complex recently renovated to very low values energy needs, this paper explores role retrofitted providing flexibility services for occupants/owners/managers and system. Key i...

This paper presents the development of an innovative and energy efficient algorithm for Heating, Ventilating, Air Conditioning and Refrigeration (HVAC-R) systems control based in thermal comfort standards. Most of the actual control of these systems is done by thermostats that measure only the air temperature but don’t take into account the air humidity neither the occupant’s individual paramet...

Most of the current studies and solutions developed for building thermal control have been designed independent of the occupant feedback. An acceptable temperature range for the occupancy level is estimated, and control input is designed to maintain temperature within that range during occupancy hours. Consider office floors with cubicles, conference rooms, student dorms, homes, and other multi...

Evidence shows that people have a major impact on building performance. Occupants’ is especially important in social housing, where their occupants may present greater vulnerabilities, and needs are not always considered. This study aims to analyse the socio-demographic influence rental housing concerning hygrothermal comfort energy consumption case located Vitoria, Spain during first 4-month p...
