First, the question of comparison is described
The Greenhouse energy data allows you to find answers to several different questions. Other decisions are supported by heating consumption of the building, following the operation of an installation or evaluating the entire growing period. The purpose and system boundaries of the test should therefore be specified before the measurement plan. The account of the whole site may include a service building or other consumer. If they change, the apparent performance of the production house may also change without changing the internal technology. The investor shall request information that can be provided to consumers, to which period and to which condition it belongs.
The area shall be accompanied by a period and a production target.
Consumption in the area may be useful, but it does not make two plants comparable in itself. The difference between the production period, crop, target conditions and external weather may also be expected. In particular, it is important to distinguish between the nominal total base area and the zone actually operating during that period. Therefore, in addition to the consumption data, changes in operating conditions should be included in the test table. M WUR Energy transition work and Hoogendoorn its data links provide a professional starting point for systemic thinking. However, the results of the own plant can only be established from local data, not from a general saving promise linked to a device.
We also log change events
It is worth recording the modification of the production programme, the launch of a new zone, the change in the screen setting and the significant closure of equipment. These events help to separate the real technical deviation from the effects of different uses. The data shall have a date, unit of measurement and named source. If a measurement replacement or a missing data is carried out, it shall also be indicated in the assessment. The location of the missing data should not be filled in with an estimate unnoticed. The estimated and actually measured quantity should be included separately in order to ensure that the operator making the subsequent decision can also see the certainty of the comparison. The well-kept diary is therefore more than a collection of accounts.
The measurement order can be constructed at the time of construction
When building a new greenhouse, the rediscussion of measuring sites, data links and access points may prevent a subsequent transformation. The plan should show which consumers are to be followed separately and who is handling the data. The accuracy of the identification and marking shall also be checked when activated. From the first period, it can be made its own starting status, to which subsequent changes may be related. The specific indicator may be used if the conditions of comparison remain in place. The decrease in consumption is, for example, a result to be evaluated, but without knowledge of the change in the production programme, it does not in itself demonstrate improved technical efficiency.
Interpretation of the comparison of two months
If one month's energy consumption is lower than the other, the first question should not be the rate of savings immediately. It is necessary to check whether the same area is the same, whether the cultivation programme is the same, and whether there is a longer stop or missing data. If these data differ, the difference in raw consumption alone is limited to technical assessment. The comparative sheet therefore includes important operating conditions in addition to consumption. The customer can see from this which conclusion is based on a truly comparable measurement and which other questions need to be collected in the next period.
Questions to reconcile the project
- Which consumers are included in the system boundary assessed?
- What area and what production programme operated during the period under investigation?
- What measurement failures and changes in operation can affect the comparison?
