A.10.3 Reporting

Reporting information regarding energy consumption, indoor conditions and

possibilities for improvement.

Reports with information about energy consumption and indoor conditions shall

be produced.

These reports can include:

a) Energy certificate for the building

b) The monitoring function which shall be used to obtain a measured rating as

defined in EN 15603:2008, clause 7.

Online monitoring functions make it possible to obtain a rating fully in conformity

with the requirements of EN 15603:2008. Measurements of the meters

can be done for an exact year according to 7.2. If a sufficient number of

meters are installed the measurements can be made for each energy carrier.

Energy used for other purposes than heating, cooling, ventilation, hot water

or lighting can be measured separately according to 7.3. Measurement of

the outside temperature facilitates readjustments of the outdoor climate as

defined in 7.4.

The rating can be used to prepare an energy performance certificate designed

according to EN 15217;

c) Assessing the ong>impactong> of the improvement of building and energy systems

This assessment can be made according to EN 15603:2008 by using a validated

building calculation model as defined in clause 9.

The monitoring functions make it possible to take into account the current

climatic data, indoor temperature, internal heat gains, hot water use and

lighting patterns, according to EN 15603:2008, 9.2 and 9.3;

d) Energy monitoring

The TBM monitoring function can be used to prepare and display the energy

monitoring graphs as defined in EN 15603:2008, Annex H;

e) Room temperature and indoor air quality monitoring

The monitoring function can be used to provide reports about air or room

operative temperatures in the rooms as well as indoor air quality. For buildings

which are not permanently occupied these functions shall differentiate

between occupied and non-occupied buildings. For buildings which are

heated and cooled the report shall differentiate between cooling and heating

periods.

The reports shall include the actual value as well as reference values such

as setpoints for example.
