LCC Tool LegnAttivo

The main purpose of the project is to optimise the production chain and to apply lean construction principles. Currently, timber retrofit solutions are rarely implemented because of the high costs involved. The project promotes energy retrofit interventions based on multifunctional prefabricated modules, aiming to minimise waste and critical issues in the production phase and thus to minimise costs. The quantitative analysis was carried out following the Life Cycle Cost (LCC) approach, evaluating the production chain of the module, including the installation phases of the system.

The tool allows the user to record all the costs connected to the - possibly multiple - façade systems of a building. It is also possible to compare costs and key performance indicators (KPIs) of different alternative façade solutions for the same building. The objects typically involved in the life-cycle costs analysis tool are a building and its façades. To one building can correspond many types of façades. Once modelled the project in terms of types of façades and its specific component/subcomponents, the user is asked to fill multiple forms with costs connected to each life-cycle phase of the façade systems.

A general feature of the tool is that the data can be inserted with different levels of detail, depending on the format and detail of the data available by the user for each case study. Therefore, the cost of a certain life-cycle phase can be inserted as a total aggregated value or divided in cost items (e.g. materials, labour, equipment…), or subdivided in components or subcomponents (e.g. Facade layers, Façade components, windows or window components such as insulated glazing unit, frame…). Independently of the compilation mode, the tool sums the different cost items of each phase in order to calculate the KPIs of that phase of the project.

The outcome of the tool is an estimation of the life-cycle costs for the system and a set of KPIs. Furthermore, the user receives a set of visual representations through graphs of the above-mentioned data.
