System Deep Dives

Plan and deliver a credible audit: walk-throughs, measurement, data analysis, and a prioritised register of opportunities.

Beyond payback: time value of money, NPV, IRR, life-cycle costing and how to compare competing projects fairly.

Combustion, excess air, flue-gas losses, blowdown and the practical levers for boiler-plant efficiency.

Steam traps, flash steam, insulation, condensate return and distribution losses across a steam system.

When combined heat and power makes sense, sizing to heat demand, and assessing economic and carbon performance.

Find, grade and reuse waste heat — economisers, recuperators, heat exchangers and heat pumps.

Optimise heat exchange across a whole process at once: composite curves, the pinch point, minimum utility targets, network design and the economics of the approach temperature.

Fabric, air-tightness, thermal bridging and glazing (U-values, g-values, low-E) — controlling loads at source.

Heating, ventilation and cooling: system types, controls, setpoints, free cooling and demand-based operation.

Heat-loss calculation, economic thickness, lagging of pipework and vessels, and surface-temperature safety.

Motor efficiency classes, variable-speed drives, sizing, power factor and managing electrical demand.

The most expensive utility on site: leaks, pressure, control strategy, heat recovery and right-sizing.

Lux levels, LED retrofits, controls, daylighting and lighting design for energy and comfort.

Shifting heating and cooling loads in time — sensible, latent and the economics of storage.

Solar PV, solar thermal, wind, heat pumps and biomass — sizing, integration and on-site generation.

Control loops, sensors and actuators, BMS strategies for buildings, and process control on industrial sites.

Commissioning and re-commissioning so systems actually deliver designed performance — and keep delivering it.

How air conditioning, refrigeration and heat pumps work; thermodynamic cycles, efficiency, optimization.

How maintenance regimes protect efficiency, and how to embed energy into planned and reactive maintenance.

Prove the savings: IPMVP options, baselines, adjustments and avoiding the traps that overstate results.
