From concept to flow
Integrated efficiency easily falls into concept wars; energy flow clears the logic. In Yantai the topic varies by district; base conditions and habits differ, so judgement differs slightly. We trust the field over desk impressions. Locally we look at demand density first, then base conditions, then siting, matching return on investment. More walks and real feedback beat desktop analysis; conclusions from the field are more reliable.
A basic judgement
Technically it has passed validation; the focus now is doing it economically and stably. One difference: experience is a long-term metric. Adapt, do not copy; stay sober about endowment. Judge by utilization over capacity, coordination with systems, cost curve in range, standard coordination smooth. We reverse from the user's real experience; smooth, safe, supported is the yardstick.
Safety discipline
Safety is non-negotiable: power, verify, tag by process; photo-archive hidden work. A pretty spec that fails daily use is decoration; we value 'dependable' over 'good-looking'. Safety as a precondition keeps integrated efficiency data trustworthy.
