Conventional greenhouses, with their high transmittance for solar irradiation and conductive nature, result in significant heat transfer to the interior. While this feature is desirable cold regions, it poses a challenge hot arid areas, causing excessive an unsuitable rise internal greenhouse temperature crop growth. passive cooling methods prove insufficient, addition, solely active both energy-intensive environmentally harmful, making economically unfeasible under certain conditions. In research, novel design optimized regions proposed, incorporating several cost-effective innovative techniques: (1) fully sunken greenhouse, (2) shaded roof openings diffuser lenses, (3) thermally insulated roof, (4) closed-loop horizontal earth-to-air exchanger. Computational modeling involved developing ray-tracing model proposed greenhouse. The results demonstrate that achieves sufficient well-distributed plant Also, shows remarkable (85.6%) reduction load during season (April October) compared conventional Furthermore, economic assessment indicate 67.8% lifetime cost of design.

This research aims to develop and validate an organizational maturity framework (OM framework) assess organization’s improve the operational performance of EQM. The study adopts a multi-methods approach. Qualitative data are sourced from 18 respondents analyzed through thematic analysis. analysis reveals that pollution control energy efficiency primary EQM concerns. assessment occurs one or multiple sources, with most preferred models being five-phase models. Finally, maturation has diverse effects on EQM, which mirrors continuous improvement expectations. quantitative involved 212 drawn PBOs across country. were SEM, culminating in hypothesis testing. Three eight hypotheses supported, including H4: Legal requirements have statistically significant impact PBO (β = −0.150, p 0.015); H5: Sustainability positive 0.169, 0.045); H1: level determines 0.066, 0.050). rest variables inverse relationship not significant. weightings for determinants culminates realization whose hypothesized relationships confirmed received moderate priority. These findings explain why only 8.8% variance maturity, while entire model explains 3% efficiency. culminate validity instructions task specificity conceptualization among PBOs.
