Could your building be wasting energy without anyone noticing?

The Building Energy Control Checker

Find out how well your organisation really understands, monitors and controls building energy use.

Many buildings waste energy through operating hours, hidden night loads, poor schedules, controls and equipment running when it is not needed.

This free diagnostic check helps identify whether those issues may be going unnoticed in your building.

No generic retrofit checklist. The questions focus on how your building is actually operating.

Before investing in new technology, find out whether the existing building is running properly

Energy-saving conversations often jump immediately to solar panels, lighting upgrades, insulation or replacement plant.

But many organisations do not yet know whether equipment is running overnight, whether BMS schedules still match occupancy, what is driving their base load, or whether contractor proposals are supported by actual energy data.

The Building Energy Control Checker focuses on those questions first.

Do you know your annual electricity and gas spend?

A No, not really B Roughly C Yes, from bills D Yes, and we track it regularly

Do you have half-hourly electricity data available?

A I don’t know what that is B No, or not easily C Yes, but we rarely look at it D Yes, and we review it

Have you looked at your overnight electricity use?

A No B Not recently C Yes, but we haven’t acted on it D Yes, and we investigate high night loads

Do you know what your building uses electricity for?

A No clear breakdown B Only broad guesses C We know the main loads D We understand major equipment and operating patterns

Do you compare energy use between occupied and unoccupied periods?

A No B Occasionally C Yes, manually D Yes, routinely using data

Do you check whether heating, cooling, ventilation or lighting run outside occupied hours?

A No B Only if someone complains C Sometimes D Yes, this is checked systematically

Do you understand your seasonal energy pattern?

A No B We notice bills go up and down C We compare summer and winter use D We use patterns to identify heating, cooling or control issues

When energy costs increase, what do you usually look at first?

A We don’t really know where to start B Supplier prices or tariffs only C Obvious equipment or lighting D Data patterns, operating hours, controls and major loads

Are BMS or time schedules reviewed after changes in occupancy or building use?

A No, or we don’t know B Rarely C Sometimes D Yes, regularly

Do you have a live list of energy-saving opportunities?

A No B Informal ideas only C Yes, but it is not actively managed D Yes, with priorities, savings, costs and status

Are contractor recommendations checked against your actual energy use?

A No B Rarely C Sometimes D Yes, we check whether proposals match the data

What best describes your current energy management?

A Reactive — we mainly respond to bills, faults or complaints B Basic — we look at bills occasionally C Developing — we review some data and opportunities D Active — we use data to manage performance
