Abstract:The energy demand in greenhouses is enormous, and high-performance covering materials and thermal screens with varying radiometric properties are used to optimise the energy demand in building energy simulations (BES). Transient System Simulation (TRNSYS) software is a common BES tool used to model the thermal performance of buildings. The calculation of the greenhouse internal temperature and heating demand in TRNSYS involves the solution of the transient heat transfer processes. This study modelled the tempe… Show more
“…After validating the model, several other simulations are performed according to the set objectives of the study. For example, a study may want to investigated the influence of different thermal screens, the configuration of thermal screens in terms of the number of layers (multi-layer or single layer) and the type of material the thermal screen is made of (polyester, Luxous, or Tempa) on the heating or cooling energy requirement of a greenhouse (Rasheed et al, 2018c;Rasheed et al, 2020a;Rabiu et al, 2022). Figure 2 shows a typical BES model in the TRNSYS Simulation Studio.…”

“…Greenhouses also extend the cultivation period to achieve a high yield, protect plants from severe outdoor weather, reduce production costs and offer the possibility of off-season cropping (Lee et al, 2012;Akpenpuun and Mijinyawa, 2018;Ghoulem et al, 2019). Although greenhouse agriculture is cost-effective, as it reduces the number of agrochemicals and water required for the production processes of crops, greenhouse crop production is one of the high-energy-consuming sectors in large-scale agricultural production (Zhang et al, 2020;Rasheed et al, 2020a;Rabiu et al, 2022). This high energy consumption associated with large-scale greenhouse agriculture has caused an increase in research aimed at innovations and technological advancements.…”

“…Recent reports include developing building energy simulation (BES) to optimise greenhouse crop production and the design and manufacture of different thermal screens and cladding materials to conserve energy or shield crops from adverse climates. These methods promote energy savings without compromising crop growth, development and yield (Yano and Cossu, 2019;Rabiu et al, 2022).…”

“…Luo et al (2005) reported that energy balance and process-based climate simulation models and applications to greenhouse climate control were carried out in the 1980s. Since then, greenhouse climate simulations conducted by various researchers have contributed to the knowledge base on greenhouse climate, light transmission, ventilation, crop transpiration, photosynthesis, energy demand, thermal screening and cladding materials (Luo et al, 2005;Ahmad et al, 2017;Rasheed et al, 2018a;Rasheed et al, 2020b;Ahamed et al, 2020;Akpenpuun et al, 2021b;Akpenpuun et al, 2021a;Rabiu et al, 2022).…”

“…Crop cultivation in greenhouses increases from highaltitude and temperate regions to low-altitude and tropical and subtropical regions due to global warming (Kumar et al, 2009;Ogunlowo et al, 2021). Hence, manipulating or regulating the greenhouse air temperature to be the same as or very close to the outdoor air temperature in the hot season is required for successful crop production in the greenhouse (Akpenpuun et al, 2021b;Rabiu et al, 2022).…”
This review documents the present knowledge and knowledge gap in applying building energy simulation (BES) dynamic models to greenhouses. The focus of this review is to compile the literature on the BES dynamic model of greenhouse microclimate, covering materials, energy requirements and thermal blankets using the Transient System Simulation version 18 (TRNSYS 18) software. Fifty-two journal articles, mostly Science Citation Index (SCI) and Scopus index journals, on BES development and simulation of greenhouse microclimate, greenhouse energy requirement, covering materials and thermal blankets were reviewed. These researchers sought to optimise greenhouse crop production. The main features of the TRNSYS 18 software for BES development are outlined; each research consulted for this review successfully developed, simulated and validated its BES. However, none of these developed models included the vapour pressure deficit (VPD) as a greenhouse microclimate factor, an essential climate parameter. In conclusion, this study demonstrates that applying a BES developed using TRNSYS has excellent potential to optimise greenhouse crop production and help adapt appropriate climate control strategies and energy-saving techniques. However, it is recommended to include VPD in future BES model development.
