3 Gross internal floor area

The gross internal floor area of a building is the area measured to the internal face of the perimeter wall for each floor level. It includes areas occupied by internal walls and partitions, columns, piers and other internal projections, internal balconies, stairwells, toilets, lift lobbies, fire corridors, atria measured at base level only, and covered plant rooms.
It excludes the perimeter wall thickness and external projections, external balconies and external fire escapes. Furthermore, unused areas such as unheated cellars or lofts are not included in the gross internal floor area. Its unit is measured in m². If you do not have this exact figure, fill in figure using a slightly different definition of the floor area.

4 Operating hours

The operating hours represents the period when the building works at 100% of its capacity and need to be calculated for the entire year. If the building is opened during 8 hours at 50 % of its capacity, then the resulting operating daily hours are 4 hours. This logic needs to be used to calculate the annual operating hours taking into account holidays, weekends etc. Previously the figure required was operating hours per week. All previous data entered has been multiplied by 52 to get an annual figure. We are aware that this figure will not be precise. Please can you check these figures but note that this is a voluntary figure and does not affect your buildings performance.

5 Service provided in the building

Please choose the service provided in the building shown in the following list.

For each service selected, enter the surface in m². Calculations will consequently take into account the mix of uses of your building.

6 The swimming pool surface area and number of swimmers per year

For a swimming pool please enter the water surface area in m². In the page for energy and water consumption, a new field will appear asking you for the number of swimmers per year. The performance indicators for swimming pools are calculated by the "total surface area of the swimming pool or swimming pools" and the water performance indicator is based on the water consumption per swimmer. So when you fill in the water consumption data, please include all of the consumption data (showers, toilets, new water for swimming pools…).
Please note that the calculation only works for indoor swimming pools.

When you are sure that you have entered all the relevant data please click on SAVE and a page will open with the message This new building has been added! You can now either add (another) building or click on the option Make a calculation and follow the instructions below to produce a poster.

Create a poster

Having registered the general information for your building you now have to enter the relevant data needed to produce a Display poster. If you have just entered your building data you can go directly to Make a calculation. However, if you have decided to first enter the data for all your buildings or wish to add data for a poster for a new year you need to go to POSTER EDITION and click on Posters. Choose the option Make a calculation and in the box below type in the first letters of the building you are looking for or choose your building from a drop down list on the right, select the relevant building and click OK (see figure below).

Choose the building to enter the data needed to produce a Display® poster

Description of the data needed to produce a poster

Here you are requested to enter the collected data that corresponds with numbers 7 to 15.

7 Reference year

The reference year is the year that you collect the following data. Please note that the declaration of the year shown on your poster always equals the year that follows the reference year.

8 Local weather correction factor

Which data are used to calculate the regional weather correction factor?

With the goal of harmonising the Display software and increasing the accuracy of your calculations, the weather correction factor is calculated using normalised European statistical data at a regional level from the European statistical institute: Eurostat.

Are those data less precise than the ones obtained from your local meteorological station?

Yes and no. As the new factors are calculated at a regional scale we are aware that some cities may have entered data that are more precise. Therefore, if you have the capacity to calculate your own local weather correction factor you will be able to replace the default regional factor with this figure. This solution has been preferred because of its European and normalised dimension. If you do not have more precise data, the regional weather correction factor will be automatically taken into consideration. If you want to obtain your local weather correction factor, ask your energy service provider or a meteorological office. The local climate correction factor comes from the comparison between the average degree heating days (DD) and the reference year i.e. : average DD for your city / reference year DD. NB. This calculation is for your local area. Do not compare the degree days for your reference year with the average for your country or another region. It must be compared with the average for your city. The correction factor normally lies between 0.85 and 1.15. A figure of 0.85 signifying a particularly cold year and a figure of 1.15 a warm year.

Is it important to have a correlation between the period that you enter your consumption data and the weather correction factor?

Yes. As the European data are collected from the 1st of January to the 31st of December each year, to create your poster for 2010 you will be required to wait until January 2011 and are also required to enter your consumption data using the same time period i.e. 1st of January to the 31st of December of each year. If you use your own local weather correction factor please make sure that the time period that you collect your consumption data correlates with the time period for your heating degree days.

Why is it important to use a weather correction factor?

Temperature-corrected energy consumption data are useful as they allow the correct interpretation of energy consumption trends and provide an accurate basis for the development of an energy policy. It avoids a potential “false” decrease of energy consumption which might come from hot weather instead of real technical or behavioural improvements.

Which data and assumptions are required to calculate the regional weather correction factor?

In order to implement a weather correction factor for final energy consumption, the following elements must be known:

- Actual final energy consumption (available from your bill or your energy meter)
- The share of energy used for space heating
- The number of heating degree-days (severity of the cold in a specific time period, taking into account the outdoor temperature and the room temperature) (calculated by Display from the Eurostat data).

How is the regional weather correction factor calculated?

To ensure a common and comparable basis, the following method is used to calculate heating degree-days:

(18°C - Tm) x d if Tm is lower or equal to 15°C and are zero if Tm is greater than 15°C

where 15°C is the heating threshold and Tm is the mean (Tmin + Tmax / 2) outdoor temperature over a period of d days.

The weather correction factor (relative heating degree-days for eurostat) is in turn defined as the ratio of long-term average degree days (30 years) to actual degree-days (be careful, it is the opposite for Eurostat). A relatively long base period is desirable to balance out the influence of short-term changes in mean temperatures. Furthermore, the degree-days and climate correction factor have to be calculated at regional level (temperature data sets from a large number of individual weather stations). Finally, the relative degree-days are weighted by population. A case study (United Kingdom) allowed us to measure the precision of two different regional levels. Although the observed differences were not significant, the more detailed regional level was finally chosen, as many public, private and academic users expressed their interest in obtaining such figures.

What is the source of the data and how have regions been defined?

The raw temperature data from 1500 weather stations are collected and processed by the Joint Research Centre (JRC) - IPSC / Agrifish Unit / MARS-STAT Action. Using a fine grid (50 km x 50 km), the JRC applies a meteorological model (during the whole year and not just the heating period (October to May)) to establish the best set of weather stations for the interpolation of temperature data at regional level (according to NUTS - Nomenclature of Territorial Units for Statistics). Once this selection has been made, the actual interpolation consists of a simple average, corrected for altitude difference. After the calculation of representative daily temperature data (maximum, minimum and mean temperature) for each grid cell, daily temperature sets are compiled for all the relevant administrative regions (régions in France, Länder in Germany, cantons in Switzerland…) to produce area-weighted averages. A further refinement through weighting by population is then made using the average annual regional population data available from Eurostat. The result is the calculation of the monthly and annual actual degree-days for the country aggregate on the basis of administrative regions weighted by population, used by Display®, taking as a reference period the years 1980 to 2009.

9 Water consumption data

Note down the water consumption of your building in the reference year. The required unit is m3. You also have the option to enter data in litres and Gallons. These figures will be converted into m3 by the calculation tool.

10 Energy consumption data

Concerning the energy consumption data, please collect the following information:
Which kind of the following energy, or energy sources, have been consumed in your building?

• Gas:
  
  • The type of gas that is used has to be specified using the drop down option. There is a choice of natural gas, liquefied gas and biogas.
    
• Fuel oil:
  
  • It is assumed that light fuel oil is used.
    
• Coal:
  
  • The type of coal that is used has to be specified from the options of anthracite and brown coal.
    
• District heating:
  
  • Further information on district heating has to be specified. Please fill your data in MWh.
    
• Wood:
  
  • The type of wood that is used has to be specified using the drop down options of logs, pellets or chips.
    
• Solar (thermal):
  
  • This line concerns the non-electrical energy production by a solar collector, e.g. for hot water.
    
• Electricity (conventional):
  
  • This line takes into account electricity that is purchased with supply contracts that do not contain an agreement about the contribution of specific primary energy sources to the overall energy mix. Please note that if you do have the distribution data for your energy supply you can specify this in 12.
    
• Electricity (green):
  
  • By default the calculation instrument assumes that wind power and hydro energy each contribute 50 % to the overall energy mix since both are the most frequently used renewable energy sources for the production of electricity.
    
• Electricity (PV):
  
  • This line concerns the electricity production using photovoltaic (PV) cells. You do not need to specify the type of your photovoltaic cells as the calculation instruments assumes that the system consists of polycrystalline silicon.
    • If you sell all the electricity that you produce: you have to specify here your PV electricity production (kWh). In addition, you must subtract the energy produced by the PV panels from your real electricity use (kWh on your electricity bill), then put that amount in the “conventional electricity purchased”.
      • Example: your photovoltaic cells produce 10 000 kWh and your electricity bill is 15 000 kWh. You have to put 10 000 kWh i n the “Photovoltaics” category and 5 000 kWh (= 15 000 – 10 000) in the appropriate electricity (conventional or green ) category.
    • If you only sell the surplus you are only required to enter your electricity consumption.

What is the allocation of your energy consumption regarding the different end uses?
Please use the following categories of end use:

• Space heating
  
• Cooling
  
• Water heating
  

Others is for all other consumption including lighting and equipment (e.g. office equipment like computers, fax or photocopiers but also pumps or canteen and workshop equipment).

11 Information on district heating, if used

Please take down the distribution for the energy source that is used in the different district heating plants:

• [%] of fossil with waste incineration
  
  • i.e. [%] of gas [%] of fuel oil [%] of waste incineration [%] of anthracite [%] of brown coal

[%] of renewable with waste heat

• • i.e. [%] of biomass [%] of solar (thermal) [%] of geothermal
    

Please do not forget to specify whether your district heating comes from a cogeneration plant by clicking on yes or no to activate and double click to deactivate.
The calculation will be made with values for an appropriate standard district heating plant. Note that it is possible to enter values which are more adapted to your local situation. In this case, you have to provide the following factors which have to be rounded to two places after the decimal point and don’t forget to use a dot, not a comma:

• Cumulative energy use factor [kWh/kWh]
  
• CO2 emission factor [kg/kWh]
  

These factors are transferred to the Display® team, who will check if the data entered meets the requirements, taking into account the parameters of the district heating system9.

12 Distribution of conventional electricity consumed

The mix of national electricity production will be used by default. If the supply contract specifies a contribution of specific primary energy sources to the overall energy mix, please enter the data in the appropriate space provided on the left hand side of the table.

13 Information on a cogeneration unit in the building

If you use a cogeneration unit in your building please ensure that you have entered either the natural gas, fuel oil (diesel) or biogas consumption in section 10) either in the column “space heating” or in the column “total” In the table fill in the overall annual electricity production of the cogeneration unit. Finally, insert the electricity production of the unit that was not consumed within your building and therefore fed into the grid in the second line.

14 Information on “simple actions” to improve the environmental or energetic performance of the building

Please write a short sentence providing information on “simple actions” to improve the environmental or energetic performance of the building. Be aware that the introduction text [“YOU can help reduce the energy and water consumption in this building today by 10 % or more! Please use energy in a sensible way:”] is identical for each poster and since the space is limited please do not write more than three simple actions and do not exceed a text length of about 100 characters for each action. The text can be allocated to two lines.
If you do not enter anything the standard text will be used.

15 Information on technical solutions to improve the environmental or energetic performance of the building

If you have already implemented or if you plan certain measures to improve the environmental or energetic performance of the building, please describe them in a short paragraph. For buildings that have already achieved class A in a certain category this text box allows you to underline these outstanding results and the measures that have been undertaken to achieve this classification. Since space is limited do not write more than three technical solutions and do not exceed a text length of 100 characters. In the case that you do not enter any text, a blank area will be left in the corresponding place on the poster.

Finishing Your Display® Poster Generation

After having filled all fields, click on SAVE to save your data. The page “Results” gives you the results of the calculation of the data that is shown on the poster, too (see figure below). Starting from this page you can finish the generation of your Display® poster by choosing the desired language for the poster. Furthermore, you can click on RESET, which doesn’t take into account the modifications made before you have clicked on SAVE.

Your individual Display® poster will be provided in pdf format. To open it you must have the software Acrobat Reader which enables you to create a local copy of the pdf file as well. The figure below shows the Display® poster for the school building of example A.

Handling Special Cases

Other energy sources:

In case you use energy sources different to those shown in section 10 you have to specify your source. Please can you inform the Display® team of these special cases and they will manually look up the corresponding conversion factors. This will be done as fast as possible.

Frequently made mistakes

There are a few pitfalls which may lead to malfunctioning of the poster generation tool which can easily be avoided:

• Make sure that you enter one of the options for gas in the Energy consumption data section (section 10). You can choose between natural gas, liquefied gas or biogas. If you do not make a selection the calculation tool will highlight this area in red .

• If you have not entered any data for “District Heating” in Energy consumption data (section 10), i.e. you do not use any district heating therefore, you should not touch the section 11 “Information on the district heating” especially that you do not have a cogeneration plant as this will cause the calculation tool to look for data in the district heating section and thus signal a mistake.

• Please to not use a comma in the field where you enter your Building name.
  
  

Manage your data

The display calculation tool has specially been designed to aid municipal managers to enter all the data for all the buildings that they manage and consumption data for consecutive years. This data is managed either via the List of buildings or List of calculations.

List of Buildings

If the name of your building has changed or if you have entered an incorrect value for the surface area it is possible to update the data by clicking on Buildings and you will automatically go to the List of buildings page (see figure below). This list provides the user with all the buildings that have been entered and a summary of each buildings category and surface. This table has a feature that allows one to order the building data.
