emvera LCA calculator (beta)

1 Project

Area is the basis for every per-m² value and for building services.

Project name Address / plot Client (company) Building type Heated net area, m² Assessment period, years

2 Materials and quantities

Quantities come from the client's drawings, BIM model or bill of quantities. Replace a DEMO factor with the national value or with a product EPD.

Material	Unit	Quantity	A1–A3 kg CO₂e / unit	Mass kg / unit	Transport km	Service life, yr	C1–C4 kg / unit	Data source	Total t CO₂e

3 Building services, site and energy

Building services (HVAC, plumbing, electrical) use a table value per m² by building type, as the Finnish method allows.

Building services, kg CO₂e / m² Site activities A5, kg CO₂e / m² Material waste on site, % Heat use, kWh / m²·a Heat factor, kg CO₂e / kWh Electricity use, kWh / m²·a Electricity factor, kg CO₂e / kWh

4 Calculation rules and client confirmation

The client sees exactly which rules and inputs will be used and confirms them before the report is issued. Any later change cancels the confirmation.

Not confirmed

Confirmed by (name) Position / company E-mail

I confirm that all input data (areas, quantities, energy use, EPDs) is correct and complete, and that the client is responsible for it. I accept the calculation rules and data sources listed above, in the stated version. I understand that the result is valid only for these inputs and this rules version.
