Buildings consumed about 40% of primary energy and 70% of the electricity in the US It is
well known that most buildings lose a portion of their desired and designed energy efficiency …

Heat pumps are increasingly being installed in domestic buildings, which is an opportunity
to reduce the energy needed to heat and cool buildings. However, this reduction will only be …

Operational faults are common in the heating, ventilating, and air conditioning (HVAC)
systems of existing buildings, leading to a decrease in energy efficiency and occupant …

Recent developments in dynamic energy simulation tools enable the definition of energy
performance in buildings at the design stage. However, there are deviations among building …

The primary objective of this paper is to rank building faults based on their impacts on the
building energy penalty and occupant thermal comfort penalty considering multiple faults …

Buildings consumed 40% of the energy in the United States, which is more than any other
sectors of the US economy, including transportation and industry. The majority of this energy …

Worldwide, buildings consume a large amount of energy, and a significant share of this
energy is wasted due to system degradation, inappropriate control systems and improper …

The aim of this paper is to propose a novel building information model (BIM)–building
performance model (BPM)–building environmental model (BEM) framework to identify the …

With local control of a large number of objects that mutually influence each other, the
problem of coordinating local control systems to achieve the best overall result arises. If the …

Buildings' heating, ventilation, and air-conditioning (HVAC) systems account for significant
global energy use. Proper maintenance can minimize their environmental footprint and …
