The reporting archive
This page documents how our reports are structured and how we arrive at the numbers in them. It's a methodology reference, not a set of case studies, and it contains no promises about outcomes for a specific building.
Report structure, section by section
Every monthly report follows the same skeleton, so findings can be compared month to month without re-reading definitions each time.
- Executive summary
- A short overview of consumption trends and the single most relevant finding of the period.
- Circuit-level breakdown
- Consumption by circuit, with comparison to the previous reporting period.
- Thermal imaging findings
- Where applicable, annotated infrared images with a plain-language description of each anomaly.
- Prioritised recommendations
- Improvements ranked by estimated impact, not alphabetically or by cost alone.
- ROI table
- Estimated cost range, expected annual saving, and simple payback period for each recommendation.
- Appendix
- Raw interval data available on request for building owners who want to run their own analysis.
Metering methodology
Consumption is measured using non-invasive current transformers clamped around individual circuit conductors inside the existing distribution board, with no cutting or splicing of wiring. Readings are sampled at short, regular intervals and aggregated into hourly and daily totals. Anomalies, an unexpected overnight draw, a load that never switches off, are flagged automatically for review before they appear in a report, so the analysis reflects patterns rather than single data points.
Thermal imaging reference approach
Surveys are carried out with attention to the conditions referenced in Czech thermal protection guidance (ČSN 73 0540) and the general practice described in building thermography standards such as EN 13187, which call for a meaningful temperature differential between inside and outside, calm wind, and dry surfaces. When conditions don't meet those thresholds, a survey is rescheduled rather than carried out under conditions that would produce unreliable images.
Common finding categories
Envelope air leakage
Gaps around window frames, door thresholds, and service penetrations that let conditioned air escape.
Thermal bridging
Balcony slabs, lintels, and structural junctions that conduct heat faster than the surrounding wall.
Standby loads
Equipment left running or in standby on circuits nobody actively monitors day to day.
HVAC scheduling
Heating or cooling running outside occupied hours, or set points working against each other.
Unbalanced phase loading
Load concentrated on one phase of a three-phase supply, reducing overall efficiency of use.
How ROI figures are calculated
Each recommendation includes a simple payback calculation: estimated annual saving divided by estimated implementation cost equals the payback period in years. Saving estimates are derived from measured consumption data specific to that circuit or that section of envelope. Cost ranges are sourced from publicly available contractor price lists for the relevant category of work, not from any vendor we work with, since we don't sell equipment or carry out installation ourselves.
