General notes

The unconditioned floor area (#34) is the parking house. There´s no direct relation to the occupancies.

As an EnOB-project the Paul-Wunderlich-Haus was under intense surveillance. Due to that it was planned, built

and monitored profounder than the other German projects, what led to smaller deviations.

The reference value and the value at design stage refer to German assessment system BNB criteria 3.1.5. (visual comfort).

At the design stage a high-peak was not explicitly defined, but 10% should not be exceeded to avoid overheating. One of the goals of the project was to reach a high daylight factor, therefore the interval has been set with an increased bottom limit. This goal was reached easily, as one can see in the Actual Operational Performance .

The reference value refers to the German VDI 3807, a nonbinding guideline on energy and water demand for buildings. The values in the guideline are from 1993, thus the difference between the reference value and the Actual Operational Performance (AOP) is not very significant.

Within this project the indicators of Materials and Waste are not collected.

The building runs with electricity solely and geothermal heating and cooling (free cooling mostly) via heat pumps. Except electricity (E1), no other energy is delivered.

The reference value is based on the OSCAR 2012 - service charge analysis. The buildings used in this study have an average age of 21 years. Criteria from the study were adjusted to the Main Custom Office (e.g. GFA, location, ...).

There is no energy that is generated on-site by now, but arrangements for an installation of photovoltaics at a later stage have been made.

The energy consumption for plugloads and external use is not measured separately.

The two dates shown are examples only. You should enter data for both years

Values for these indicators are not available. It would have been too much effort to measure or calculate them.

There are no separate meters for these data, thus W1 can not be divided any further. The values have not been calculated at the design stage.

The reference value refers to the VDI 3807, a nonbinding German guideline on energy and water demand for buildings. The values in the guideline are from 1993, thus the difference between the reference value and the Actual Operational Performance (AOP) does not have a high significance. The differences between the design stage and AOP is a consequential figure caused by W1.

General notes

An intense consulting regarding energy ef

ook place during the planning phase of the BMUB.

The project is still in it´s monitoring phase, that requires a fine-tuning phase in order to optimise the interaction of services.

The data of 2012 and 2013 analysed within SB Challenge 2014 derive from this fine-tuning-phase.

The proper evaluation of the consumption for the monitoring is possible since 2013 and will be finished in 2015.

Only with the differentiated consumption analysis it will be possible to make a statement about the deviance and as a result to take

corresponding measures to optimise the operation process.

The reference value refers to the German Building Cost Information Service (BKI 2013 - High Standard divided by factors for the region (Berlin) and the year 2012 and changed from GFA to NFA). The increase of construction cost has different reasons. Main reasons are the passive house standard, the refurbishment of the existing building and the fact that ministry buildings have higher security standards. Other reasons are for example a complete exchange of screed, difficulties with plaster in the existing building or difficult soil conditions and a dugout from World War II, that caused an
