SERVICES OVERVIEW

Three ways to start reading your building

Each service takes a different instrument to the same building. Together they cover pattern, warning, and schedule.

INTRODUCTION

Which service suits your building depends on where you're starting from

If nothing has been measured yet, the consumption analysis is usually the right first step. If equipment failures are already a recurring issue, predictive maintenance may matter more. If your building's occupancy has shifted, a schedule review is worth a look. None of this needs deciding on your own — a short conversation is enough to point toward the right one.

THE SERVICES

Choose where to begin

Utility statements and a laptop showing a consumption chart

SCOPE: 3 WEEKS

Consumption Pattern Analysis

Establishes when consumption occurs, which systems account for it, and how much is drawn outside occupied hours — using data the building already produces.

  • — Written report with consumption by system and hour band
  • — List of adjustments worth examining
  • — No new equipment required to begin

¥21,500

HVAC unit with sensor wiring attached for monitoring

SCOPE: 5 WEEKS

Predictive Maintenance Setup

Watches operating data from air conditioning and ventilation equipment for the drift that tends to precede a fault, and raises a note before a breakdown occurs.

  • — Sensor connection and threshold configuration
  • — Monthly summary for the first quarter
  • — Findings are advisory, not automatic

¥29,000

Building automation panel showing lighting and HVAC schedules

SCOPE: 2 WEEKS

Control Schedule Review

Compares timing schedules for lighting, HVAC, and ventilation against how the building is actually occupied.

  • — One site visit included
  • — Revised schedule proposal
  • — Expected effect stated with uncertainty

¥16,200

HOW TO CHOOSE

A simple way to narrow it down

Nothing measured yet

Start with the Consumption Pattern Analysis to see the overall picture first.

Equipment failures recur

Predictive Maintenance Setup addresses drift before it becomes downtime.

Occupancy has changed

Control Schedule Review checks the schedule against the building as it's used now.

Not sure

Send a short note describing your building and we'll suggest where to start.

SHARED ACROSS SERVICES

What every engagement includes

Plain-language reporting

Findings written for facility staff, not just engineers.

Advisory findings

Nothing is changed automatically on your systems.

Comfort discussed first

Occupant-facing changes are proposed, never applied unilaterally.

Stated uncertainty

Expected effects are given a realistic range, not a fixed figure.

VALUE & INVESTMENT

What the price covers

Each price reflects the analyst time, sensor configuration, and reporting involved in that scope of work — not a subscription or ongoing fee unless separately agreed. Payment terms can be discussed directly if your organization has particular requirements.

FAQ

Common questions before deciding

Do I need new sensors before starting?+

Not for the Consumption Pattern Analysis — it begins with existing utility data. Predictive Maintenance Setup does involve connecting sensors as part of its scope.

Will anything be changed on my systems automatically?+

No. All findings are advisory. Anything affecting occupant comfort is proposed for discussion rather than applied.

Can I combine more than one service?+

Yes — many buildings start with the analysis and move to schedule review or predictive maintenance afterward, though there's no requirement to do so.
