Environmental module
Module workflow
The environmental module in IMPACT Project Manager is a tool where you can analyze the environmental impact of a project with LCA (Life Cycle Assessment).
An EPD (Environmental Product Declaration) consists of 3 modules: A, B and C. The calculation covers steps A1-A3. This is the information that is known about the project in PM.

Define materials
The LCA calculation is performed in One Click LCA, developed by Bionova. Therefore, all building parts in the model have to be defined by resources from the environmental data base in One Click LCA. This is performed in 3 steps:
- Concrete composition
- Factory consumption
- Other materials
Concrete composition
To calculate the impact from the concrete, the concrete composition needs to be defined.
Domain - List of domains, used to filter the resources
Sub type - List of sub types, used to to filter the resources
Resource - List of.resources
Percentage (0-100%) - Share of the resource in the concrete composition
Distance (km) - Distance to the factory
Update - Save the data in data base
Add - Add new resource
The sum of all resources in a concrete composition should be 100%.
Factory consumption
To calculate the impact from the factory consumption, information about the energy use and the amount of waste produced during the production of the building elements is needed.
Select period - LIst of factory period
New - Name, time period and number of tonnes produced during this time period (M)
Edit - Edit the factory period selected
Resource - List of.resources
Amount - Amount of energy or waste during the time period (A)
Unit - The unit changes based on the selected resource. Energy (kWh), waste (kg)
Update - Save the data in data base
Add - Add new resource
The information about the weight of the building elements used in the project is known from the model (m). The amount of energy or waste that was used for the building elements in the project (a) is calculated as a=A*(m/M).
Factory consumption is added to the calculation for the building parts marked as produced in a factory.
Other materials
The same procedure as in the tab Concrete composition is performed in the tab Other materials to define the composition of the material in the material categories reinforcement, insulation and cim.
Domain - List of domains, used to filter the resources
Sub type - List of sub types, used to to filter the resources
Resource - List of.resources
Percentage (0-100%) - Share of the resource in the concrete composition
Distance (km) - Distance to the factory
Update - Save the data in data base
Add - Add new resource
The sum of all resources in a material composition should be 100%.
Calculate
After the calculation is performed, the result as CO2 emissions is presented in the module. It is possible to continue to the One Click LCA web service for further investigation of the result. On their web service, it is also possible to insert more indata and calculate for other modules in A-C.
