You can probably tell a client how much a landscape costs, but….. can you tell them the total cost to install, operate and maintain the landscape for 25 years?
You have probably had to look at interest rates when installing landscapes, but….. did you ever evaluate the impact of different interest rates on the cost of a landscape?
Clients often ask how much their utility (water) costs for a landscape would be, but….. can you show them the costs?
Have you ever had clients ask about the amount and cost of fertilizer and pesticides needed to maintain their landscape and….. were able to show them?
Have clients ever asked what the energy costs or savings of their landscape might be and….. then showed them?
Clients almost always ask how to water their landscape, but….. did you tell them how much this would be annually and showed them how much it would be over 25 years?
You have probably had clients ask how much it will cost or how long it would take to maintain their landscape, but….. could you tell them how much that would total over 25 years?
Finally, are you able to show clients alternative landscape designs and answer all the questions above including which design is the most sustainable with the lowest cost and effort?
IF NOT….. YOU ARE IN THE RIGHT SESSION ! AT THE RIGHT TIME !
This Website, which will allow basic user inputs and manipulation, is currently receiving finishing touches and will be available for your use shortly. The spreadsheets of collected data that form the basis of the website are now ready for your use. (Click here to download) A user’s manual in .pdf format is also available for download.

Your input will help us polish this tool, which we hope will be valuable to homeowners, property managers, and landscape professionals alike.
Value Landscape Engineering Lifecycle Analysis Final Report & User’s Guide to the Spreadsheet Program Submitted to: Central Utah Water Conservancy District Project Grant WG-2075 December 2009 Updated January 2010
2. Enable macros (if you use Mac Excel 2008 or later or do not wish to enable macros, see directions for using the program without macros in the Appendix).
3. Select the “Cost Summary” worksheet. Enter names in Green-shaded cells to describe the different landscapes you wish to study (each landscape is a separate column). Enter assumptions and data to describe landscapes in Peach-shaded cells. Light blue-shaded cells show intermediary calculations made by the spreadsheet program and Purple-shaded cells show final results calculated by the spreadsheet program such as lifecycle costs, required inputs, and impacts.
4. Enter initial assumptions that will apply to each landscape you will study. 5. Enter the total landscaped area and planting coverage for each landscape. 6. Enter the purchase price and the lifespan (number of years before an item needs to be replaced) for each planting material, landscape feature, structure, and all maintenance equipment. 7. Select the desired maintenance level. 8. Examine results such as annual operating and maintenance costs and inputs and impacts over the life of the landscape. 9. Modify the assumptions you made and data you entered in steps #4 – 7 as needed.
