ENERGY ENGINEERING · DATA · AI · M&V
Understand energy use.
Verify the savings.
We connect field engineering with MES, EMS and BEMS data to identify optimization opportunities, build energy baselines and evaluate savings under comparable operating conditions.
An independent knowledge platform for industry, building operators, energy professionals, researchers and educators.
EXPERTISE
Start with the system.
Then interrogate the data.
Energy use depends on equipment, demand and operating constraints. We analyze them together to turn data into practical operating decisions.
Review our scope, deliverables, illustrative fees and next steps before commissioning an energy analysis.

Separate operating improvement from changing conditions.
Production, weather and operating hours can differ before and after a project. A baseline estimates expected energy use under the reporting period’s conditions, providing a fairer comparison with actual use.
Define the measurement boundary, relevant variables and adjustment rules before evaluating performance.
Understand the process and energy flows.
Review equipment, service requirements, operating conditions and the measurement boundary.
Align production and energy records.
Check meters, units, timestamps and abnormal data before fitting a model.
Model expected consumption.
Use relevant production, load, time and weather variables; assess model performance and applicability.
Evaluate savings and their limits.
Compare adjusted expectations with measured use, maintaining equivalent service and reporting the evidence clearly.
10 SELECTED ENGLISH CASES
From diagnosis to defensible conclusions.
Targets, potential, annualized estimates and field-based results are labeled separately. Simulation output is not presented as verified energy savings.
CASE01 · Manufacturing
PotentialHeat-treatment baselines and standard operating conditions
Production-weight baselines explain electricity use in SHAFT heat treatment and tempering. Comparable 432 kg batches reveal opportunities to reduce operating variability and excessive processing time.
CASE05 · Manufacturing
PotentialReducing forming-process downtime and increasing lot weight
A regression baseline links former electricity consumption to downtime and production weight. The analysis evaluates lower idle time and larger production lots as a route to improved energy intensity.
CASE08 · Manufacturing
Annualized estimateResolving simultaneous heating and cooling in a semiconductor facility
AHU operating data revealed overlapping chilled-water and steam valve operation. Seasonal changes were applied first to general-purpose AHUs, while cleanroom systems were treated separately to protect production conditions.
CASE18 · Manufacturing
PotentialCompressed-air UPI and control optimization in a chemical plant
Low- and high-pressure compressor systems were benchmarked using specific electricity consumption, unit staging, pressure and BOV/IGV behavior. Additional savings opportunities were identified even though baseline performance was already better than the peer average.
CASE26 · Water & wastewater
Field comparisonVerifying inlet-pump efficiency after replacement
Five-minute and monthly operating data were used to compare wastewater throughput and electricity before and after inlet-pump replacement. Flow-normalized performance improved while the reported treatment capacity remained broadly comparable.
CASE34 · Buildings
TargetFrom BEMS monitoring to continuous building performance optimization
A BPOS proposal connects existing BEMS data, design-load review, measurement checks and real-time operating guidance for a supertall mixed-use building. Seasonal optimization is designed as a continuing process.
CASE39 · Data centers
TargetReal-time PUE diagnosis and cooling optimization across data centers
A multi-center performance-improvement proposal integrates facility, IT and cooling electricity with operating data. It connects PUE to cooling-system causes and recurring optimization actions.
CASE40 · District heating
Baseline-based M&VWeather-adjusted M&V for smart district-heating operation
Heating degree days (HDD) and historical heat-meter data establish an adjusted baseline for a residential district-heating system. Smart supply-temperature control is evaluated against that baseline and cross-checked with household heating consumption.
CASE53 · Manufacturing
Field data / Test & AdjustChilled-water setpoint optimization through Test & Adjust
A manufacturing chiller-system case examines whether raising the chilled-water leaving-temperature setpoint can improve system efficiency while satisfying process, HVAC and dehumidification requirements.
CASE87 · District heating
SimulationWeather-adaptive supply-temperature guidance for district-heated apartments
A historical-weather simulation compares conventional outdoor-air reset with an hourly demand-aware supply-temperature guide. The outputs describe setpoint differences and improvement potential, not measured heat savings.
