“…Lifecycle assessments often refer to the Lifecycle Cost, though a substantial part of sources recognise its importance also from an energy point of view. The energy balance (of final energy, primary non-renewable or total) can be verified over the entire lifecycle of the building (e.g., 50 years) or on an annual basis, and is mainly calculated between energy consumption and generation but it can also concern grid import and export (Barrutieta et al, 2023). Furthermore, it is possible to distinguish between physical and balance boundary (Voss et al, 2012), with differences between on-site and off-site productions and a match between import and export.…”

This paper focuses on the research topic and application of Positive Energy Buildings (PEBs) and Districts (PEDs), and explores the state-of-the-art in the use of LCA analyses on energy impact and CO2eq emissions. An analysis of the scientific literature and existing programmes, standards and regulations is carried out to understand the evolution of the debate on PEBs and PEDs and their implementation. This analysis allows to better define the scope of applicability and assessment of PEBs/PEDs through the lens of the Life Cycle Assessment to extend its definition beyond the sole usage phase. The study also highlights the main gaps and the aspects to be encouraged to promote their diffusion.

“…The findings contribute to enhancing NZEB design and achieving energy efficiency goals [ 10 ]. Notably, several countries within the International Energy Agency (IEA) have embraced the concept of net zero energy buildings as integral long-term objectives in their energy rules and regulations [ [11] , [12] , [13] ].…”

“…Recent studies also focus on reducing greenhouse consumption [27,28], and this is best carried out in the design stage rather than when the greenhouse has already been built. The assessment of potential renewable energy alternatives, with emphasis on the photovoltaics energy for a greenhouse, also represents a current trend [29][30][31]. For greenhouses to be more efficient, the use of renewable energy sources must be correlated with the reduction in energy required for cooling and heating.…”

The market for smart greenhouses has been valued at USD 1.77 billion in 2022 and is expected to grow to 3.39 billion by 2030. In order to make this more efficient, with the help of Internet of Things (IoT) technology, it is desired to eliminate the problem of traditional agriculture, which has poor monitoring and accuracy control of the parameters of a culture. Climate control decisions in a greenhouse are made based on parameter monitoring systems, which can be remotely controlled. Instead of this adjustment of the measured parameters, it would be preferable from the point of view of energy consumption that they should be calculated at optimal values from the design phase of the greenhouse. For this reason, it would be better to perform an energy simulation of the greenhouse first. For the study carried out in this work, a small greenhouse (mini-greenhouse) was built. It was equipped with an IoT sensor system, which measured indoor climate parameters and could send data to the cloud for future recording and processing. A simplified mathematical model of the heat balance was established, and the measured internal parameters of the mini-greenhouse were compared with those obtained from the simulation. After validating the mathematical model of the mini-greenhouse, this paper aimed to find the optimal position for placing a normal-sized greenhouse. For this, several possible locations and orientations of the greenhouse were compared by running the mathematical model, with which the most unfavorable positions could be eliminated. Then, some considerably cheaper “mini-greenhouses” were made and placed in the locations with the desired orientations. Using sensor systems and technologies similar to those presented in this work, the parameters from all mini-greenhouses can be monitored in real time. This real-time monitoring allows for the simultaneous analysis of all greenhouses, without the disadvantages of data collection directly in the field, with all data being recorded in the cloud and other IoT-specific advantages being made use of. In the end, we can choose the optimal solution for the location of a real-size greenhouse.
