Green and low-carbon engineering should begin with actual energy use, equipment condition and operating requirements. A baseline is established before selecting technologies, followed by design, implementation, commissioning, O&M and performance verification.
Identify the main issues: energy consumption, comfort, equipment efficiency, maintenance cost, operational reliability or carbon impact, and define the project boundary.
Use site surveys, equipment information, operating data and energy data to create a basis for comparison and avoid unsupported savings claims.
Depending on the project, measures may include energy-system optimisation, controls and digitalisation, equipment upgrades, waste-heat utilisation, PV and storage, envelope measures or functional materials.
After implementation, commissioning, acceptance and ongoing O&M are required, with control strategies refined using operating data.
Energy savings, ROI and performance improvements should be based on project data, normalised methods or clearly defined measurement boundaries.
No. Renewable energy is one possible pathway. Projects may also involve energy management, system optimisation, equipment O&M, building-envelope measures and functional materials.
A fixed figure should generally not be promised without a project baseline and defined conditions. Expected performance should be assessed and later verified with operating data.
