zero emissions cities | buildings | products
The road to zero emissions, measured and documented.
Zebuild prepares LCA studies, Environmental Product Declarations, green building certifications and EU Taxonomy reports for cities, developers and manufacturers who need numbers they can defend in front of a verifier.
One stop shop for every ESG need.
From the carbon footprint of a single product to a company's sustainability report, in one place. We work with material manufacturers, contractors, designers, developers, municipalities and banks. Each service line below can be contracted on its own or as a package, depending on where the project stands.
LCA, EPD and carbon footprint
Life cycle assessments for products and whole buildings, type III environmental declarations prepared for verification and publication, emission inventories for manufacturers.
LCA & EPD detailsGreen building certification and energy modelling
End-to-end coordination of LEED, BREEAM, EDGE and Green Homes certification, backed by dynamic energy modelling in IES VE: credit strategy, simulations, evidence, dialogue with the assessor and responses to review comments.
Certification detailsEU Taxonomy and sustainable finance
Alignment reports under Regulation 2020/852 for new buildings, renovations and acquisitions, covering the DNSH criteria and minimum safeguards, in the format banks and auditors expect.
EU Taxonomy detailsBuilding performance testing
Thermography, airtightness (blower door), acoustic and indoor air quality measurements for the handover of nZEB buildings and for the evidence certification schemes require.
Testing detailsESG reporting and decarbonisation strategy
Scope 1, 2 and 3 inventories, reduction targets, decarbonisation plans for companies and municipalities, and sustainability reports aligned with CSRD / ESRS, prepared for limited assurance.
ESG detailsLCA and EPD for construction products
From production sheets to an environmental declaration any designer can cite.
We model the product to EN 15804+A2 and ISO 14025, using primary data from the plant and recognised background datasets. The result is a project report ready for independent verification and an EPD that can be published with any programme operator accepted in Europe.
For buildings, we run whole-building LCA for the LEED impact-reduction credit, for BREEAM Mat 01 and for the embodied carbon requirements of the EU Taxonomy.

Certification, compliance and testing for buildings
LEED
A realistic scorecard from concept stage, coordination of consultants, preparation of forms and evidence, and responses to GBCI design and construction reviews.
Talk about LEEDBREEAM
Pre-assessment, credit tracker, staged evidence collection and preparation of the submission package for new construction, major refurbishments and buildings in use.
Talk about BREEAMGreen Homes
Certification of homes and residential developments: checking the technical criteria, coordinating with the designer and contractor, documentation for the assessor.
Talk about Green HomesEU Taxonomy
Alignment reports for activities 7.1, 7.2 and 7.7, with the analysis of substantial contribution, DNSH criteria and minimum safeguards, in the format lenders require.
Talk about EU TaxonomynZEB testing
Thermography, blower door, acoustics and indoor air quality, with reports you can use at handover, in disputes or as certification evidence.
Book a testEDGE
IFC's certification for resource-efficient buildings: modelling in the EDGE app, meeting the 20% savings threshold in energy, water and embodied carbon, documentation for the auditor, and the Advanced and Zero Carbon levels.
Talk about EDGEEnergy modelling in IES VE
Dynamic building simulation in IES Virtual Environment: the ASHRAE 90.1 baseline model for LEED, EPRNC calculation for BREEAM Ene 01, thermal comfort, daylight, and optimisation of envelope and services before detailed design.
Request an energy modelESG and CSRD reporting
Double materiality assessment, Scope 1–3 inventory, targets and decarbonisation plan, ESRS-compliant sustainability report and support through the limited assurance audit.
Talk about ESGEmission reporting: Scope 1, 2, 3 and avoided emissions
Greenhouse gas inventory according to the GHG Protocol and ISO 14064-1, with clear organisational boundaries, documented emission factors and a calculation register any verifier can follow.
Combustion in owned installations, vehicle fleet, process emissions, refrigerant leaks.
Purchased electricity, heat and steam, reported with both methods: location-based and market-based.
All 15 upstream and downstream categories, with a focus on purchased goods, transport, use of sold products and leased assets.
The reductions your product or service enables at the customer compared with the reference solution, calculated and reported separately from the inventory, following WBCSD guidance.
Avoided emissions are not part of the GHG Protocol and are never netted against Scope 1–3; we present them as a distinct indicator, with an explicit baseline scenario and assumptions, so the claim withstands verification and greenwashing scrutiny.
How we work
The same path whether we are talking about an EPD, a certification or a taxonomy report. Each stage has clear deliverables, so you always know where the project stands.
- AnalysisWe understand the product, building or transaction and the lender's requirements.
- StrategyWe set the target, the credits to pursue and the list of evidence needed.
- DocumentationWe collect the data, build the models and write the reports.
- VerificationWe prepare the package for the assessor, verifier or auditor.
- Follow-throughWe answer comments until the certificate is issued or the EPD is published.
Environmental engineering services for construction in Romania
Zebuild is a one stop shop for the ESG needs of material manufacturers, real estate developers, contractors, municipalities and financial institutions. We focus on life cycle assessment, environmental product declarations, green building certification, EU Taxonomy and CSRD reporting, decarbonisation plans and building performance testing.
Life cycle assessment (LCA)
We carry out LCA studies for products, materials and whole buildings. The analysis shows where impact concentrates, lets you compare design alternatives and supplies the data required in tenders, certifications and sustainability disclosures.
Environmental product declarations (EPD)
We prepare type III environmental declarations from data collection through verification and publication. A properly drafted EPD opens the product to certified projects and to public procurement with environmental criteria.
LEED, BREEAM, EDGE and Green Homes certification
We coordinate certification from target setting to certificate issue: credit strategy, energy modelling in IES VE, evidence, calculations, dialogue with the assessor and responses to review comments.
EU Taxonomy and nZEB testing
We write alignment reports under Regulation 2020/852 that banks and auditors accept, and we perform on-site testing — thermography, blower door, acoustics, indoor air quality — for nearly zero-energy buildings.
