Comparative Performance Assessment of Air-Source and Ground-Source Heat Pumps Using COâ‚‚ and R-410A with Water Well Integration: A Simulation Study
This study investigates the performance and feasibility of heat pump systems for residential space heating in cold climates, with a particular focus on ground source heat pumps (GSHPs) with water wells. Four configurations are modeled and compared, a CO2 air-source heat pump (ASHP), an R-410A ASHP, a CO2 GSHP with water well integration, and an R-410A ground-source heat pu…

Field evaluation of zone temperature response to control actions in cooling systems of small and medium-sized office buildings
The response of zone temperature to control actions in heating, ventilation, and air conditioning (HVAC) systems, known as zone temperature response, has been a central focus of building control research owing to its crucial role in determining control performance. However, existing studies often overlook the representativeness of the buildings being studied, resulting in…

Privacy-Preserving Average Consensus With Beaver Triple and Communication Obfuscation
A privacy-preserving average consensus algorithm is proposed that synergizes the Beaver triple in secret sharing theory and noise obfuscation. The algorithm safeguards the initial values of agents against passive adversaries in a multiagent system. It is proved that the proposed algorithm can concurrently ensure average consensus and privacy, while also reducing the online…

Thermal and electric multidomain dynamic model for integration of power grid distribution with behind-the-meter devices
As renewable energy sources like solar and wind power become more integrated into the grid, coordinated control of behind-the-meter devices is crucial for enhancing grid flexibility and reliability and for meeting cost targets, with standardized models being developed to support this transition. The increasing flexibility and uncertainty of integrated renewable energy grid…

Deploying advanced supervisory control strategies to small- and medium-sized commercial buildings: Case study and lessons learned
Deploying advanced supervisory control strategies (ASCSs) in small- and medium-sized commercial buildings (SMBs) is vital but faces two issues: (1) a lack of building control and communication infrastructure (BCCI) in SMBs and (2) the significant engineering efforts required to implement and configurate ASCSs. Despite hindering the large-scale adoption of ASCSs in SMBs, th…

Multitarget Control Models for Building Thermal Comfort and Indoor Air Quality – A Critical Review
The control techniques in buildings contribute significantly to thermal comfort and indoor air quality (IAQ). However, the gaps are existing for multitarget controls considering both thermal comfort and IAQ. They are: (1) both experimental and modeling control studies were conducted for thermal comfort, focusing on temperature and humidity. (2) All three (physical, grey-bo…

Transactive control for grid-interactive efficient commercial buildings
Transactive control (TC) is a type of distributed control strategy that uses market mechanisms to coordinate distinct objectives of individual entities. Through grid-interactive efficient buildings, TC can help achieve power balance in the electrical power grid under high penetration of renewable energy. This paper presents a SH{standard} TC approach for commercial heating…
