Once your current building needs have been evaluated, the next logical step is to calculate whether an upgrade or replacement will allow these needs to be met more efficiently.
1. He loves me, he loves me not: It may sound silly, but compiling a list of the pros and cons for a replacement and for a new BAS will help you flush out the major implications for each BAS track. Some food for thought:
- Ease of new(er) system operation
- Training time- in dollars AND hours
- Maintenance expectations
2. Take it easy: How easily can the upgrade be implemented? An easy upgrade path should ensure the level of functionality will be met. Lots of ‘well, you won’t be able to…” or “now you’ll have to” may mean a new system is the more efficient outfit.
3. Take it to the limit: Evolution in the building automation field has brought immense changes to BAS capabilities. The tradeoff of increased system performance at a lower cost has been that made many older but perfectly functioning systems are now obsolete. Many of those systems simply are not compatible with the architecture employed in new system designs, making an upgrade a clumsy option.
4. It’s not me, it’s you: Finally, it’s useful to evaluate the relationship with the vendor that supports the existing system. Vendor issues weigh heavily in the decision-making process, but be careful not to confuse the lack of vendor support with poor system performance.
