For your own results, you need your own system limit
The assessment of the water and energy efficiency of greenhouse starts with the indication of the measured quantity and the chosen system boundary. The same does not show the whole site, a growing zone or a single installation. The investor should first specify what operational question he wishes to receive. M WUR Its circular gardening and energy transition work gives a professional background to the connection between material flows and energy. However, the results of their own results are taken from local measurements. The example presented by a producer percentage or another plant cannot be automatically considered as having proven the performance of that horticulture without the same conditions and system boundaries.
The period and the production target should be comparable
The assessment of two series requires the same or clearly named period and state of use. The change in the area, crop and production programme in operation may give a different meaning to the same raw consumption. Weather and operational events shall also be taken into account. The denominator of the specific indicator shall be clearly described, not estimated overall size. The customer must also request a brief explanation of the initial conditions. Thus, it can be seen which conclusion relies on comparable operations. The smaller total consumption alone does not demonstrate better technological performance when fewer zones or different cultivation programmes have been operating during the period considered.
Why, estimated and missing data should be included separately
The certainty of the data is part of the interpretation of the result. The quantity from the meter, the estimate calculated and the missing period should not be fused into a single line that appears to be certain. The customer knows the source of the quantity tested. The history of the measurement replacement, new adjustment or change of connection should also be maintained. The impact of the opt-out shall be mentioned in the professional evaluation. The aim is not to treat the uncertainty of all data as identical, but to make the right limit visible. The valuer can therefore decide on which questions to answer the existing data and what additional measurements are required for the following period.
Date and content of intervention
The effect of a new umbrella, modified water system or a changed operational programme can only be tested with known history. Please note in the log when and at which system boundary the change occurred. The technical content of the previous and new condition shall be identifiable. The customer thus does not attach a general modernisation label to different consumption. The change in use shall also be assessed separately in the study. If several interventions were taken at the same time, the reason for the total deviation cannot be automatically attributed to a single element. The documented state and local measurement together will help to verify the outcome of the operation of the own plant.
The result decision is also named
Efficacy data is useful if it shows the next test or operational question. The customer and professional team can decide which discrepancy justifies system verification and which is linked to known production changes. The study shall maintain an explanation of the system boundary, period and data source. The disclosure of own results is understandable and thus does not extend the experience of a single period of investigation to any future situation. The investment decision shall include a specific assessment of the confirmed local situation and the remaining issue. The water and energy data will therefore support the understanding of their own greenhouse, not the repetition of an automatically taken over marketing statement.
Questions to reconcile the project
- What precise system boundary and production period is the data?
- How is the measured quantity, estimate and data loss separated?
- What simultaneous technical or production change affects the conclusion?
Professional background
The related international system solutions are provided by these primary manufacturers and execution sites. The decision aspects of the project shall be interpreted independently by the article; the specific size and content of the undertaking shall be clarified on the basis of the investment data.
