Building LCA
We support you in developing building LCA studies to strengthen your project, boost your competitiveness in tenders and meet the environmental requirements set out by Green Building Rating Systems
- Increase your chances of achieving rewarding scores in construction public procurement
- Support the Technical and Economic Feasibility Study with a solid environmental assessment.
- Prepare for future requirements on embodied carbon in buildings (EPBD IV)
Building LCA Consulting
The LCA study of a building (Building LCA or Whole-building LCA) allows for the assessment of environmental impacts of a property throughout its lifecycle, considering the main phases: material production, construction, use, and end-of-life.
This type of analysis is not just a technical tool, but is increasingly in demand in public tenders, in particular those governed by Green Public Procurement for Construction, in the Sustainability Report for the Project to be attached to Technical and Economic Feasibility Study, and in the main Building certification protocols, such as LEED or BREEAM.
This type of analysis particularly includes whole life carbon (WLC) of the building, which includes both the embodied carbon – related to materials, transport and construction – both the operational carbon associated with the building’s use phase.
In many cases, the LCA study is accompanied by aLCC Analysis (Life Cycle Costing), which also allows for the assessment of costs throughout the building’s life cycle. TheLCA-LCC integration allows for the support of design choices, taking into account both environmental and economic impacts, especially in the context of tenders and design.
Ollum offers support in the development of LCA/LCC studies of buildings. Our technical support is specifically aimed at:
- Design and architecture studios
- Engineering companies
- General contractor and construction companies
- Procurement authorities and public bodies
- Property developers and operators
An LCA study for a building is typically required when:
1. Green Public Procurement (Construction)
It allows you to access bonus points in public tenders: designers and contractors can gain competitive advantages by committing to developing a LCA-LCC building studio.
2. Project Sustainability Report (PFTE)
It supports the drafting of the report required by the Public Procurement Code, by providing the estimations of the life-cycle assessment (LCA) of a building and its carbon footprint of the project right from the initial stages.
3. Building Rating Systems (LEED, BREEAM) and the EPBD IV directive
Building LCA contributes to obtaining criteria related to embedded carbon reduction and to the improvement of environmental performance; furthermore, it prepares you for the upcoming european obligations on whole life carbon, increasingly central to building design (EPBD IV directive).
Why use a Whole-Building LCA support service?
The Building LCA it is a very useful tool, but not always straightforward to be set up internally. Relying on specialist support helps you transform a technical study into a concrete tool for tenders, projects, and certification:
Set up a study that is genuinely useful for Green Public Procurement
We don’t just produce an analysis: we structure the study based on the context in which you need it, so that it is consistent with the tender, with the work’s Sustainability Report or with the certification protocol.
Reduce the risk of methodological errors and wasted time
We support you in defining the scope, data collection and modelling, avoiding improvised approaches or analyses that are difficult to defend.
Get concrete directions to improve the project
LCA studies aren’t just for “doing a calculation”: they help you compare solutions, identify critical points, and steer the project towards choices with a lower environmental impact.
What steps are involved in our consulting services for building LCA studies?
Our consulting support for the preparation of an LCA or LCC study for a building follows these steps:
1. Initial analysis and perimeter definition
We define the objectives, level of detail, and application context of the study: Green Public Procurement, Green Building Certification, or project evaluation.
2. Data collection and model building
We will collect the project data and set up the building’s LCA model according to the applicable methodology.
3. Calculation of Impacts and Reading of Results
We quantify the environmental impacts throughout the life cycle and analyse the project’s main contributions.
4. Optimisation and comparison of scenarios
We support the team in identifying improved alternatives to reduce impacts, embodied carbon, or any issues that have arisen.
5. Reporting and documentary support
We shall prepare the necessary documentation for the tender, including the Sustainability Report for the Project, Green Public Procurement for Construction, or certification protocols.
What standards does the building’s LCA study draw upon?
The reference technical standard is the UNI EN 15978:2011, which defines the calculation method for assessing the environmental performance of buildings and applies to both new and existing buildings, as well as refurbishment projects.
