[Bldg-sim] Life Cycle Cost Analysis (UNCLASSIFIED)

[Paul Erickson]

John,

Having completed numerous LCCA and economic feasibility studies we've also tried to find this sort of information and have found it in short supply.  As Jeremy noted RS Means can serve as a source, albeit a limited one, especially for the many "advanced" systems being evaluated for projects (i.e. chilled beams, VRF, geo, etc.).  Vendors and our clients' maintenance staffs tend to be the most reasonable sources, though there are some challenges there as well.



It would be great to find a more robust O&M cost data set that's publicly shared, especially with data from the likes of BOMA and GSA.  In the meantime, in lieu of having a high level of confidence with numbers you're finding, I would suggest a sensitivity analysis around the O&M costs to help gauge the impact and provide the basis for a "risk & reward" conversation with your client.



Regards,

Paul

RS Means has a "Facilities Maintenance & Repair Cost Data Book"

available at http://rsmeans.reedconstructiondata.com/CostBooks.aspx.

Otherwise, you could possibly contact your local BOMA affiliate to see

if they have general data they are willing to share on these.

Group,



After doing the energy model of two different systems I was asked to do

a

life cycle cost analysis.



I am able to look up every needed value (equipment cost, equipment life,

installation cost, energy cost, inflation rate, fuel costs.)



I can site where I got each number. (right or wrong, I have the source.)



The only missing number is operation and maintenance costs.  Where can I

look

up O&M and site the source?



I am comparing a geo-thermal system with a boiler/chiller system.
