“…Digital technology can reduce the burden on designers, display the design comprehensively and intuitively, and allow for scientific modification and deletion of materials. It also facilitates global perspective analysis and efficient storage [6]. The use of digital technology improves the quality and effectiveness of work, making the design process more flexible and efficient.…”

“…This outcome suggests that the confidence of German nationalities in their climate change knowledge is unreasonably uncertain given their actual knowledge. Kudoma and Tekere (2021) assessed the stakeholder's perceptions of the environmental impact of HCFC-22 phase-out and found out that 97% were of the view that phase-out of HCFC-22 had a positive impact on the environment; it reduces HCFC-22 emissions, thereby reducing ozone depletion and global warming effects.…”

Environmental problems such as global warming, ozone depletion and climate change remain universal subjects of concern, with baneful effects on both the environment and human health. The consumption and venting of ozone depleting substances (ODS) into the atmosphere are the chief anthropogenic cause of ozone depletion. One such manmade ODS with high global warming potential Chlorodifluoromethane (HCFC-22). The MP targeted to phase-out HCFC-22 with obligatory cut-off timelines for its use by 2040 for developing nations. To comply with the HCFC-22 phase-out timelines, meant at embarking on national communications to disseminate information on HCFC-22 phase-out through key stakeholders’ involvement. The achievement of HCFC-22 phase-out strategy depends on participation of key stakeholders in the implementation process. the level of awareness and product knowledge of service stakeholders in the importation and distribution of HCFC-22 in Botswana. customs officers, officers and industrial consumers. Questionnaires and interviews were used to solicit key stakeholders’ views, opinions and perceptions on HCFC-22 phase-out awareness and product knowledge. Results revealed that 87% of the stakeholders are learned and knowledgeable in ODS related service provision. The level of HCFC-22 knowledge and awareness among stakeholders is moderate with distinguished inter-group differences. In particular, industrial consumers had the highest median level of HCFC-22 awareness than other stakeholders, indicating gaps in HCFC-22 phase-out awareness raising and training. About 67% of respondents had low levels of awareness of the HPMP and alternative technologies to HCFC-22. This proposes gaps in information dissemination to key stakeholders and this remains a crucial disparity between the country’s HPMP success lead and lag indicators. There is need to carefully select communication media used in line with the media consumption habits of target markets. Use of popular and commonly accessed social-media platforms would ensure that the HCFC-22 phase-out messages have high chance of reaching targeted stakeholders and the general population.

“…The environmental constraints set out in the Montreal Protocol (1987) on the protection of the ozone layer and the Kyoto Protocol in 1979 on the protection of the climate requires the search for new refrigerants. Halogenated hydrocarbons with high ozone depletion potential (ODP) have been banned under the Montreal Protocol due to their harmful effects on the ozone layer which protects the planet from ultraviolet rays [2][3][4][5][6].…”

An energy analysis study carried out on a vapor compression refrigeration cycle using refrigerants with low global warming potential (GWP) of the Hydro-Fluoro-Olefin (HFO) type, in particular R1234yf and R1234ze fluids to replace HFC refrigerants . Computer code was developed using software for solving engineering equations to calculate performance parameters; for this, three HFC type fluids (R134a, R404A and R410A) were selected for a comparative study. The results showed that R1234ze is the best refrigerant among those selected for the mechanical vapor compression refrigeration cycle. The thermodynamic analysis showed the effect of the evaporator temperature (-22 °C to 10 °C) and the condenser temperature (30 °C to 50 °C) on the steam cycle performance. Compression refrigeration, including the coefficient of performance. The results showed that the HFO-R1234ze with low GWP gives the best coefficient of performance of 3.14 close to that of the R134a fluid (3.17). In addition, R1234ze is considered an alternative fluid to R134a for their ecological properties.
