Description Purpose: to share the feasibility results with the client who will use them to
determine the best option according their requirements
Content of the exchange: feasibility results
Detailed exchange data::
o LCC (Euro/m2) o ROI (years) o Low energy demand o Renewable Energy Source (%) o Self Sufficiency rate (%) o Primary energy need for electricity, heat, cooling (kWh/m2)
o Energy Supply Reliability, including the reliability of local grid (%)
o Environmental Impact
Possible tools: GIS Simulation tool
Possible format for data exchange: GML, cityGML, XML
One way exchange

3.4. Functional parts
Each functional part provides a detailed technical specification of the information that
should be exchanged. Since that action may occur within many exchange
requirements, a functional part can be linked to one or many exchange requirements.
Therefore, maintaining the balance in the level of granularity for exchange is critical
to ensure that they are not context specific, otherwise it would be difficult to use them
in multiple applications in various exchange models related to different context
(buildingSMART, 2010).
Below in the figure 6 is shown a detail for a functional part, it contains the technical
information specified in the information exchange template. To carry out with the
feasibility results data is required to exchange lifecycle cost, return of investment, low
energy demand, renewable energy sources, self-efficiency rate, primary energy needs,
energy supply reliability and environmental impact.

4. Conclusions
This research has pointed out the collaboration problems in BPS field as consequence
of a low interoperability, having a clear urgency to improve it in order to obtain the
early collaboration benefits claimed by BIM.
The standard information exchange approach does not work in a real situation given
that in most of projects each consultant uses their own tools. Additionally, no tool is
able to create the entire data required for a project through the life cycle. Then to
generate the whole data in a project will be need to use an integrated information
exchange approach that will allow using any tools. Nonetheless the formats used to
manage the interoperability are not good enough and some data is missed in the
process.
Overcome the interoperability issue requires using Information Delivery Manual
methodology to improve the information exchange within an IFC file. IDM is a
procedure simple enough to allow the communication between technical and non-
technical users via plain language. However for further stages it will be need to
validate the IDM with the IFC structure, in doing so, the programmer will understand
which data is required by the user.
While the servers analysed are able to read the IFC format, the analyse shown that
most of these servers are not reliable enough to manage data, being likely to miss data
or that external actors could access to the information, then creating a server with
security standards will be a must in order to keep safe the data.
