The COVID-19 pandemic led to the mass adoption of remote working and other office market dynamics. As firms continue to adapt to the changes caused by the pandemic through various work patterns, the potential implications for the office market are unclear. Using data from Knight Frank’s (Y)OUR SPACE (2021) survey, this paper employs probit and multinomial models to examine the relationship between COVID-19 related remote working and changes to firms’ office space strategies. The study confirms that the pandemic has significantly influenced firms’ medium-term office space use strategies, and the results show that firms’ perception of their employees’ work-from-home experience has influenced their strategy review. The results specifically show that a positive WFH experience increases the likelihood that firms will reduce their total space quantity, reduce their density of occupation, and negotiate shorter leases in the medium term. We further observe that the pandemic is likely to have weaker effects on space quality than on space quantity, implying that economic factors remain core priorities in future office space use strategies, while social and environmental factors may remain secondary. These insights extend the literature beyond the economic determinants of office space demand to other social factors.

Sentiments about hybrid working have changed in line with the waning of the Covid-19 pandemic. Businesses and organizations are increasingly driving a return-to-office (RTO) mandate, which questions previous perceptions about reimagining office space use and the ESG and economic impacts at the pandemic apex. Using data from two waves of Knight Frank's (Y)OUR SPACE survey (2021 and 2023), we employ probit models to analyse the link between the COVID-19 pandemic and workspace dynamics. We also compare the influence of business strategies and work patterns on office space use expectations during the lockdown and 2 years after. The results indicate that the COVID-19-driven hybrid working led to firms’ decisions to reduce their office space quantity while improving the quality of space. However, these sentiments and expectations are changing in line with post-pandemic work culture and organizational strategies. Our results further reveal that office space flexibility may not be a priority in organizations’ future workspace strategy. These insights indicate that economic factors remain core priorities in future workspace strategies while environmental and social factors remain secondary. This study extends the literature beyond the economic drivers of workspace strategies to environmental and social factors.

Over the course of industrial manufacturing, additional heat within the extract systems is usually released into the atmosphere and its intrinsic energy is wasted. This paper investigated a cold abatement smoke extract system for a fire testing wall furnace to determine the viability in recovering heat from the hot smoke. Three scenarios were investigated: 1) the extract system was closed and only 300°C smoke was present; 2) the system took in ambient air around the furnace and heat recovery occurred at 80°C in smoky air; 3) the smoke had been removed from the air and the temperature was 60°C. It was found that there was a significant build-up of soot on Scenarios 1 & 2 with a build-up rate of 0.25 μm/s which totalled 2.7 mm of soot after a three-hour test. The soot had a low heat transfer rate and therefore acted as an insulator on the heat exchanger which reduced the efficiency significantly of it over time. Due to this loss in efficiency, it was more viable to recover heat in Scenario 3 at 60°C in clean air than it was to recover heat at 300°C or 80°C in smoky air. The results show that having clean air was more important than a higher temperature when it came from recovering heat from a cold abatement system for a fire testing furnace. This paper contributes to reveal the possibilities of harnessing the “waste heat” for use in other applications in the vicinity of the manufacturing processes, such as heating water within a central heating plant, domestic hot water or electricity generation, or re-cycled within the industrial plant itself.
