As far as I know, the cost of $6000 a year is kind of like annual subscription fees for the LDP. After 12 months, you’ve to return the LDP back to USGBC in good shape. Then I start wondering what’s in return after paying $6000 other than renting a digital display and proud to be telling we’re LEED believer. Don’t forget, there are many software and hardware out in the market can do the similar things tie-in the BMS to displaying real time electricity use, carbon emission, water use, IAQ, etc. In fact, the building owner can have more choices custom made what information and message want to display. Instead of giving $6000 away to rent the LDP, USGBC shall consider providing useful technical analysis and advises to the LDP user based on the collected real data, such as sending quarterly report to the building operator and owner. I believe USGBC is capable and shall do the analysis because of owing a large database. USGBC may outsource to 3rd party qualified professional doing the analytical job if worrying the liability issues. The building owner can understand what’s run wrong and making decision to tweak the building systems right away by reading the report. That USGBC diagnostic report not only allow the building owner to fine tune the building performance, it can give chance to the building operator or contractor to do better jobs improving the building. Then I will say $6000 a year is worth every penny.
Wing. It's THREE year contract...you can't return it at the end of a year. Yes there are options that might make the LDP a useful piece, but those are really only as an adjunct to LEED EB ...not as a poor substitute.
