“…In addition to the strategies discussed, there are other energy saving technologies for HVAC systems. The recent technological advancements in terms of HVAC system designs include but are not limited to the following: demand controlled ventilation systems (Cui et al , 2020); duct sealing (Harrington and Modera, 2014); logic control and FDD systems (Zhao et al , 2019); use of microchannel heat exchangers (Khan and Fartaj, 2011); variable speed drives (Schibuola et al , 2018), and variable flow volume systems (Lu and Warsinger, 2020). According to Merema et al (2018), demand controlled ventilation (DCV) system is one of the possible strategies that can be adopted to enhance the energy efficiency of the HVAC system by automatically adapting the airflow rate according to the actual ventilation demand.…”

PurposeHeating, ventilation and air-conditioning (HVAC) systems account for approximately half of all energy usage in the operational phase of a building's lifecycle. The disproportionate amount of energy usage in HVAC systems against other utilities within buildings has proved a huge cause for alarm, as this practice contributes significantly to global warming and climate change. This paper reviews the status and current trends of energy consumption associated with HVAC systems with the aim of interrogating energy efficiency practices for improving HVAC systems' consumption in buildings in the context of developing countries.Design/methodology/approachThe study relied predominantly on secondary data by analysing the relevant body of literature and proposing conceptual insights regarding best practices for improving the energy efficiency of HVAC systems in buildings. The systematic review of the literature (SLR) was aided by the PRISMA guiding principle. Content analysis technique was adopted to examine germane scholarly articles and finally grouped them into themes.FindingsBased on the SLR, measures for enhancing the energy efficiency of HVAC systems in buildings were classified based on economic considerations ranging from low-cost measures such as the cost of tuning the system, installing zonal control systems, adopting building integrated greenery systems and passive solar designs to major approaches such as HVAC smart technologies for energy management which have multi-year pay-back periods. Further, it was established that practices to improve energy efficiency in buildings range from integrated greening system into buildings to HVAC system which are human-centred and controlled to meet human modalities.Practical implicationsThere is a need to incorporate these energy efficiency practices into building regulations or codes so that built environment professionals would have a framework within which to design their buildings to be energy efficient. This energy efficient solution may serve as a prerequisite for newly constructed buildings.Originality/valueTo this end, the authors develop an integrated optimization conceptual framework mimicking energy efficiency options that may complement HVAC systems operations in buildings.

“…A sealant is injected into the building space during construction in coordination with an air leakage pressurization test, and the sealant finds its way to leaks and seals them. Results of controlled testing on lab-constructed enclosures, as well as limited field testing on single-family new construction and existing homes, have been very promising (Harrington and Modera 2014).…”

“…Eventually, enough particles build up that they seal the leaks entirely. Initial evaluations of the process indicated the potential for large reductions of building air leakage (Harrington and Modera 2014).…”

“…The Western Cooling Efficiency Center at the University of California-Davis has performed controlled testing on lab-constructed enclosures as well as limited field testing on single-family new construction and existing homes to demonstrate the concept of aerosol sealing. Preliminary data from those tests have been very promising, yielding at least a 50% reduction in enclosure leakage in test homes (Harrington and Modera 2014). In single-family homes, the benefit of air sealing is well documented and understood.…”

The work presented in this report does not represent performance of any product relative to regulated minimum efficiency requirements. The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described. Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions. Overall, the aerosol sealing process has the potential to shortcut other very labor-intensive methods for sealing apartments, including the airtight drywall approach. x
