BIMSPEED Library, while trying to guarantee the maximum reliability and completeness of the information, declines all responsibility for incorrect, missing or inconsistent information relating to the website data and contents. BIMSPEED Library does not guarantee that the site or its contents, services or features are error-free or that the use of the site's data and services by the user will lead to the achievement of specific results. The user assumes full responsibility for the use of the site and the functions and services connected to it, especially the data associated with elements created or modified. The user assumes sole responsibility in relation to any activity concerning his account, username and / or password, attributable to his conduct, failure to intervene or negligence. Before data publication, BIMSPEED Library carries out a review of the presence of the data in the packages of the elements created by external users, but in no cases assumes any responsibility for the accuracy, completeness, quality or validity of the contents created or modified by user.
The BIM-SPEED library is an online database of components for building renovation. The components include parameters which are usable for running energy performance and sustainability (LCA and LCC) analyses. The database is available at https://bimspeedlibrary.com/
The aim of the BIMSPEED Library is to offer construction building stakeholders a catalogue of the most common BIM objects for building renovation, such as the components used for the building envelope (insulation materials and panels, facades and ventilated facades, windows, external doors), the HVAC systems (Water Heating System, Air/Water Conditioning System, Small VRF, Multisplit, Ventilation) and the DHW system. Each dataset is composed of a set of parameters useful for running energy performance and sustainability assessments, supporting the renovation design and the decision-making process.
The parameters included in the renovation objects are referred to the respective EN or ISO standard. Some examples are: the fire class which is referred to EN 13501-1:2019; the energy class, which is referred to the European Directives depending on the considered HVAC and DHW component (such as “Commission Delegated Regulation (EU) No 1254/2014”); the LCA and LCC data, which are referred to ISO 14040, ISO 14044, EN.
The BIMSPEED library collects enhanced .ifc files of renovation building components, therefore it could be used as input for any tool who uses .ifc files. APIs are available to allow the readability of the db by external services.
The library can be connected to the “IFC Material Enricher Service” tool by CSTB (a test was performed by CSTB). The library can also be connected with “Model Checker” tool by DEMO, which allows to specify a set of rules and conditions with which a model should comply; the API developed to connect the library with Model Checker supports the specific search criteria required to find a matching element in the database.
The library could be connected to “Cypetherm Eplus” tool as additional input database and to the “BIM_based LCC” tool, but tests are not available, yet. It could be also indirectly used for the “Multicriteria decision making” tool for the “BEM Generator” tool for helping the design and the analyses of the building renovation solutions. The database is also connected
The BIMSPEED library is available on the BIM-SPEED platform (in the Kroqi system).
The BIMSPEED database contains materials and components used for deep renovation of buildings. Building renovation components are defined as the building elements that can provide a contribution to the reduction of the overall energy consumption and/or to an enhanced environmental and economic sustainability. They can be summarized in the groups and categories reported in the table below.
The types of elements depend on the component category; some of them are reported in the table below for an easier exposition.
The datasets include a set of parameters, which can be divided into two packages: the “info package” and the “software package”. In particular, the info package collects the general information, such as the component category, the typology, the application area, and others; whilst the “software package” collects more specific information, i.e., the data needed as support for energy performance assessment, Life Cycle Assessment (LCA) and Life Cycle Costing (LCC). Data collected for the energy performance assessment vary considering different components categories.
Energy performance parameters are different for each building component type and can be listed in the table below.
In the LCA package, the information related to the environmental impacts generated during the production stage (A1-A3 of standard EN15804) are considered, with reference to a fixed unit of measures, called “Functional Unit”. In the LCC package, the information related to the economic impacts generated during the Production (A1-A3 stages), Construction (A4-A5 stages), Use stages (B stages) are considered. For the LCA and the LCC, the data included in the database are reported in the table below. It can be noted that the LCA parameters are equal for all the categories, whilst the LCC parameters differ for the envelope and HVAC/DHW categories, because an additional cost info is collected, i.e., the operational energy cost.
The database has several aims: it offers general construction building stakeholders an updated catalogue of building renovation components where they can choose, with the help of research filters, the more appropriate element for their purpose; then, it also provides specific datasets useful to perform energy assessment and environmental/economic analyses using ad hoc external tools and/or software.
The figure below shows the database workflow which interacts with several input data, external services and a web portal, available at bimspeedlibrary.com. The database represents the back-office platform for partners to manage the different renovation elements, which are in parallel published on a public web portal designed for general users who can simply navigate the website or download and modify the elements upon online registration process. The database can be enriched by different types of input files coming from: external libraries, the project demo cases, the partners who can easily create new elements or edit existing ones. The latter aspect can be done either through manually entering data or through an automatic procedure that involves loading, reading and editing of existing IFC files. Finally, specific APIs allow the connection with external services aiming to use the renovations elements present in the BIMSPEED database for their analysis purposes.

Going in detail, more specific indications on the database compilation starting from market general renovation building components and market components used in the renovation design alternatives of the Demo cases are provided. These datasets have been included in the database, through a wizard-based procedure (figure below). The information required by the database are:
Figure 2: Main Information about the New Element
Once the dataset is completed, a confirmation is required in order to start the review process. Indeed, the element is directly classified in the status of “draft”, i.e., an element created by a registered user which can still be edited by the author. If the data entered is sufficient, the user can send the element for review to the administrator. At this point the author will no longer be able to make changes to the element. Once a check has been made on the element, the administrator can decide, also at the request of the author, to set the element as draft again (in order to allow the author to make changes) or, if there is no need to modify the data, to publish it on the portal. After publication, the element will be available to other general users.
Therefore, the dataset can have the following status:
With this procedure, a total number of 239 renovation objects have been collected.
The process just explained can be summarized in the following figure, showing the process map of the BimSpeed Library tool.

Demonstration Cases:
The BIMSpeed Library provides a set of potential alternatives for DEMO cases renovation design, in terms of choice of building components.
For the Frigento Demo, 59 components have been included in the library. They can be listed as follows:
As an example, Figure 3 shows a possible insulation panel to be used for the Frigento demo renovation (left) and its info package in the BIMSPEED library.
Figure 4: Inclusion in the BIMSPEED library of one insulation panel, which could be used in the Frigento Demo
Frigento Demo Case is a residential two-storey building, located in Via Duomo 64, 83040 Frigento, Avellino - Italy. It is an historical masonry building, built in 1700 and renovated in 1980. The internal surface is 328 m2.
Figure 5: Frigento Demo
In addition, if the IFC files are available for some components of the DEMO case, it is possible to modify them with an enhanced version using an ad-hoc procedure developed within the database. Indeed, when a user creates an element, he can also upload its IFC file, based on the data firstly inserted in the several packages. If the user later modifies or inserts additional information, then he can also generate a new IFC file containing the updated data, which will appear in the list of available files without removing the previous one. This procedure also works with existing IFC files.
**Please, consider that for each of the components listed, more than one dataset is included in the library, given the different dimensions available on the market (e.g., the insulation panels widths)
The BIMSpeed Library can be used in the renovation stages of a project. The following the process map section shown in Figure 6, the user can identify the Energy, LCA and LCC parameters related to each building component and choose the ones that better fit the project’s aims (e.g., low environmental impacts, low costs, best energy performances evaluated after performance assessments on the model which includes the selected BIM object).
