FAQs for offices and corporate businesses

Where is energy used most in office and corporate environments?

Most office energy is used for lighting, air conditioning, heating, computers, monitors, and server equipment. Larger corporate spaces also rely on multi‑floor HVAC systems that run for extended hours and contribute heavily to overall usage.

Why do office electricity bills increase during certain seasons?

Bills usually rise in summer and winter due to increased air conditioning or heating. HVAC systems work harder to maintain comfortable temperatures, especially in larger buildings where climate control must cover multiple levels.

How can small and medium offices reduce their energy costs?

Offices can lower costs by comparing plans regularly, switching off unused equipment, optimising air conditioning settings, upgrading to efficient lighting, and reviewing contract terms before they roll onto higher rates.

What drives high energy usage in corporate and multi‑floor buildings?

Large offices experience higher consumption due to extensive HVAC systems, long operating hours, large lighting grids, server rooms, and equipment that runs continuously. Running multiple systems at once can also increase demand charges.

How can multi‑site or multi‑floor operators improve energy efficiency?

Operators can align contract end dates, benchmark usage across locations or floors, install monitoring tools, review tariffs, upgrade outdated equipment, and use energy insights to identify peak consumption periods.
