The main goal of LCC DATA was simplifying the access as well as storage possibilities of cost information to ease and extend the use of LCCA in construction, and hence improve the decision process towards more sustainable buildings.
This meant defining cost categories and develop databases for storing and benchmarking of costs, and further ensure simplified data exchange between different ICT-tools used in planning and decision. Realistic LCCA, as a good basis for decision making, requires easy accessible data in all phases from brief to construction, where statistic information, key numbers and experience data is valuable information.
More available input data will remove one of the main barriers of taking LCCA in more active use. Easy access to comparable data also gives the building owners possibilities to benchmark their building, with emphasis on energy use and operation cost. This will lead to more focus on the operation of buildings, as well as improvement of energy efficiency.
During the project period, the project team have in cooperation with building owners and facility managers collected and sorted in use information, especially of running costs, taking into account what data is already available in other forms. This process was, in addition to building up the data base, a process giving the building owners a closer relation ship to the systemised cost information, and the possibility to internal and external comparison and bench marking. Finally the collected data and treated cost information were used to calculate LCC in the brief and design phase of planned buildings. The pilot cases were used to show different solutions concerning energy use and
Tools and methods for calculation of energy demand and LCC were used for different building projects throughout the project. Guidelines for integrated planning process, recommended in LCC-REFURB, were also used.
The project consortium is consisted of partners for Norway, Austria, Czech Republic, Germany, Greece, and Slovenia, all with long experience in energy efficiency and use of LCC.
Results
The cost classification proposed is shown in deliverable D4. The main categories are as shown below:
- Capital costs
- Administration costs
- Operating costs
- Maintenance costs
- Development costs
- Consumption costs
- Energy
- Heating
- Cooling
- Electricity for equipment and installations
- Water and drainage
- Waste Handling
- Cleaning costs
- Service costs
Case studies
The case studies are described more in deliverable D16. The common factor for the cases were to do LCC analysis in early stage by use of key number, statistics etc, and later in the design phase with more case specific cost.
The purpose was both to train and demonstrate use of LCC on different levels, and also to compare the results being able to say something about usefulness of use of key number calculations. |
