MEP Engineering FAQ

Common questions regarding AC energy saving and MEP retrofitting

What must be reviewed before an HVAC energy retrofit?

Whole-building HVAC retrofits are usually scheduled in months. Variable-speed upgrades and added ice storage are scheduled according to the work involved. Equipment and construction costs are itemized, with temporary cooling listed separately. Work can be phased, with changeovers at night or on days off. Backup chillers can maintain cooling during the work. After a site survey, we provide a shutdown and restart plan.

How is ESCO work scoped?

An ESCO arrangement puts energy improvements and performance measurements into a contract with a baseline, savings terms, costs, and responsibilities. Funding and benefit allocation need agreement before adoption.

How is performance measurement scoped for an ESCO project?

Use pre-upgrade energy and operating records to establish a baseline, comparison conditions, measurement period, and calculations. Record differences in weather, production loads, and operating hours for a fair comparison.

What is the technical principle of the Nano-Ice Crystal Cold Storage system?

Thermal storage holds cooling energy when demand is lower and releases it for air conditioning when needed. Material and equipment choices have different operating conditions, specifications, maintenance needs, and connections.

How are production and construction arranged during a retrofit?

Equipment changeovers or piping changes may require shutdowns. Phased work, shutdown windows, or temporary supply can support production schedules. Share essential equipment and hours to define impacts and contingency measures.

How are financial items assessed for MEP energy work?

Compare equipment and installation costs, shutdown or temporary-supply costs, and energy and maintenance spending before and after changes. Rates and operating hours affect results; share bills and operating records.

Which site conditions are suitable for further assessment?

Factories and facilities where HVAC, refrigeration, hot water, compressed air, or process equipment dominate energy use are suitable candidates. Start with high-consumption, long-running, or frequently failing equipment.

How is maintenance arranged after a retrofit?

Costs may rise or fall depending on consumables, service frequency, and repair methods. Proposals itemize warranty, inspections, consumables, and staff tasks so you can compare existing and replacement equipment.
