Where ABIE works

Different buildings.
Different demands.
One intelligence framework.

Explore how ABIE assesses performance against the service each building needs to deliver, from occupied offices to critical cooling and heat networks.

ABIE / Site briefing

Comfort is delivered and mechanical effort is elevated. Level 3 carries the gap.

Occupied spaces held 22.1 °C inside their 21–23 °C band all day; comfort delivery scored 92. Mechanical effort scored 64. Level 3 is dragging on the site: eleven of its fan coils are working harder than expected and getting less back for it, heating and cooling at the same time from 07:40 to 10:15 each morning.

One open fault, since 3 September: the cooling valves are not following their command. Level 3 carries all of the recoverable value, an estimated £12k a year at the same comfort. Fixing the eleven cooling actuators recovers it.

Operating priority

Balance occupant comfort, energy consumption and operational efficiency.

From valve response to a focused finding

Compare each valve’s command with its actual position. Heating valves followed their commands while cooling valves did not, moving the explanation from a control overlap to the cooling actuators. Relate the affected intervals to the floor’s chilled water meter and maintained comfort when estimating recoverable value.

Assessment boundary

Occupied office building and its connected HVAC, annualised eligible operating hours

Assessment basis

  • Comfort / Service Delivery / Required serviceAuthored assessment

    92 /100. Authored contextual service index: occupied spaces held 22.1 °C within a 21–23 °C band throughout yesterday. The score is not calculated from that temperature alone.

  • Mechanical Effort / Relative to dutyAuthored assessment

    64 /100. Authored Mechanical Effort assessment: eleven Level 3 fan coils heat while cooling valves fail to follow their commands. The score is not an efficiency percentage or a percentage calculated from a single reading.

  • Recoverable Value / Principal exposureAuthored assessment

    12000 GBP/year. Authored scenario estimate of £12,000/year, based on the eleven fan coils’ valve positions and the floor’s chilled water meter at maintained comfort. Heating valves follow their commands; cooling valves do not. The underlying meter series, annualisation and tariff are not published here, so this is a supplied estimate rather than a reproduced calculation or verified recovery.

Performance scores run from 0 to 100: higher is better against the applicable duty. These authored assessments are separate from physical quantities and exposure dimensions.

Component evidence

  • Usage / Level 3 / eleven fan coils

    Concurrent. Heating valves followed their commands; cooling valves did not, leaving chilled water flowing against the heating. Valve-command and position histories distinguish a cooling-actuator response fault from the initial control-overlap hypothesis.

Evidence & measurement coverage

The scenario includes occupied-space temperatures, command and position histories for eleven Level 3 fan coils, and the floor’s chilled water meter. The £12k annual estimate is supplied for this scenario; underlying meter series, annualisation and tariff are not published here. It is not verified savings.

Systems in view

AHUs, cooling and heating plant, distribution circuits and terminal equipment.

Assessment assumptions

  • The 92 comfort-delivery and 64 mechanical-effort scores are contextual assessments, not percentages calculated from a single temperature or valve reading. Level 3 accounts for the full £12k annual recovery estimate.
  • Recovery is estimated at the same level of comfort and remains subject to verification after the cooling actuators are fixed.

Operational finding

Simultaneous heating and cooling. Level 3 carries all of the recoverable value, an estimated £12k a year at the same comfort. Fixing the eleven cooling actuators recovers it.

Integration & limitations

Recoverable value requires a supported energy basis and tariff. An opportunity is not realised savings.

Source descriptions do not assign an ACS grade, a coverage percentage or a statistical confidence.

Beyond these environmentsPublic-sector and government estates, retail and shopping centres, laboratories and life sciences, and logistics or industrial facilities with suitable building services.

The shared challenges

Different environments.
Familiar performance challenges.

Unnecessary energy use

Equipment working harder or running longer than its duty requires.

Reduced service delivery

Heating, cooling or ventilation falling short of appropriate expectations.

Operational risk

Equipment conditions that expose the continuity of an important service.

Disconnected information

Faults, metrics and operating conditions that need to be understood together.

From evidence to responsibility

FM / M&E operations

Address the eleven Level 3 cooling actuators identified by the valve-response evidence.

Engineer

Verify cooling-valve response after the actuator work, then compare the floor’s chilled water use at the same level of comfort.
