Question 1
Read the following passage carefully and answer the questions given below it.
A review into the history of offices illustrates how office design has always been led by dynamic changes in society. Across the world, work-from-home (WFH) has been rising steadily for over a decade, peaking suddenly in spring 2020 due to the COVID-19 pandemic. The governments' restrictions imposed internationally to fight COVID-19 mandated people to stay in their homes and triggered the largest ever ‘experiment’ of home working. Online platforms and technology-enabled solutions facilitated the full transition of white-collar working activities from office-based to remote, home-based working. Now as we see buildings, cities and countries reopening, it is important not to lose focus on flattening the curve for energy use and CO2 emissions, as a way to tackle climate change. Energy use in office buildings has seen a considerable rise in recent years due to the expansion in office floor space and the increase in building utilisation, the prolonged occupancy hours, the significant growth in information technology, and the extensive use of air-conditioning. Although this trend is partly offset by considerable improvements in building envelope efficiency, evidence shows that small power and lighting account for a significant proportion of energy end-use. In offices, especially open plan ones, lights often remain on even when the space is no longer being used. Masoso et al. conducted a monitoring study of five office buildings and revealed the “shocking quantities of energy being wasted during non-occupied hours in commercial buildings”, with more energy used out of hours (56%) than during working hours (44%) due to occupants leaving lighting and equipment on at the end of the day. Space cooling is also cited as a significant cause of energy use in offices. Uncontrolled solar gains due to extensive glazing facades, higher internal gains due to increased use of IT equipment, and poorly controlled artificial lighting can all cause overheating and result in increased cooling demand in the workspace.
Which of the following statements can be definitely deduced about WFH from the passage?
(I) Work from home became more prevalent after the breakout of the COVID-19 pandemic.
(II) Offices voluntarily decided to make their employees work from home.
(III) System of working from home was new for everyone during the COVID-19 pandemic.
