Kristel,
This is a good question to ask before jumping in.
My best answer is “it depends”.
As an architect you are looking at a WBLCA which manages up to six building systems (structure, enclosure, interiors, MEP, site, FFE). Most architectural firms start with structure, and enclosure, as these are usually well-modeled in Revit.
The numbers I am providing are based on the following assumptions:
- You and your firm have a background in reporting operating carbon emissions, and you want to use an LCA tool to calculate embodied carbon emissions only.
- Your structural consultant uses Tally and understands the BIM rigor required so that you can use their structural model.
- You will be using proxies for your Interiors, FF&E, and MEP. CLF has published excellant resources here (MEP and TI).
- You are not including Site & Landscaping in your pilot project.
The time required (assuming two staff minimum) to complete your pilot project is estimated at 40-60 hours per person.
You also need to realize that completing this pilot project will set in motion additional time requirements to continue performing WBLCAs, including training of staff, coordinating BIM with your consultants, developing internal standards, quality control, working with your consultants to develop LCAs of their systems, etc. Each WBLCA you perform will require less and less time, and it may take you as much as a year to understand what your final costs will be for each WBLCA.
These suggestions represent my opinon only and your actual time spent could be higher. Please accept this information as a starting point that will hopefully be corroborated or challenged by others in this forum.
