Frequently asked energy questions for construction and trades

How is energy used in construction and trade businesses?

Energy is used for workshop lighting, power tools, equipment charging and temporary site power. Larger construction sites also rely on HVAC systems for site offices, cranes, lifts and machinery that draw higher loads.

Why do energy costs vary across construction projects?

Costs change as projects move through different stages. Early phases require basic site power, while later stages need higher loads for machinery, HVAC, tools and lighting. Seasonal temperature changes also increase heating or cooling needs on site.

How can small trade businesses reduce their energy bills?

Small trade businesses can reduce costs by comparing plans regularly, managing workshop equipment usage, upgrading lighting, organising off-peak charging for batteries and reviewing contract terms before expiry.

What drives high energy usage on large construction sites?

High consumption is usually caused by temporary HVAC in site sheds, cranes, lifts, large machinery, compressors and extensive lighting. Running multiple high-load items at the same time can increase peak demand charges.

How can construction firms improve energy efficiency across multiple sites?

Firms can reduce costs by aligning contract end dates, reviewing tariffs, tracking site-by-site usage, staggering equipment operation and using energy insights to identify peak periods. Upgrading temporary lighting and managing HVAC also improves efficiency.
