THE PROMISE

A clear picture of where consumption happens

By the end of three weeks, you'll have a written account of which systems draw the most, at which hours, and how much of that draw happens when the building is empty. For most owners, that last figure is the one they hadn't seen before.

THE PROBLEM

A monthly bill tells you the total, not the story

Most owners know their overall energy cost but not which system is driving it, or whether equipment is running when no one is in the building. That gap is easy to live with until it isn't — and it usually stays invisible without a proper look at the data.

THE SOLUTION

Reading what your building already records

We work from existing utility data and, where available, sub-meter readings — nothing new needs to be installed to begin. The analysis attributes consumption to lighting, air conditioning, ventilation, refrigeration, and hot water, then breaks each down across hour bands so patterns outside occupied hours become visible.

THE EXPERIENCE

What the three weeks look like

WEEK 1

Records collected

Utility statements and any sub-meter exports are gathered and organized.

WEEK 2

Pattern built

Consumption is mapped against system and hour band to form the reading sheet.

WEEK 3

Report drafted

Findings are written up with a list of adjustments worth examining.

AFTER

Report shared

You receive the report and can raise questions before deciding on next steps.

THE INVESTMENT

¥21,500

Covers analyst time, data organization, and the written report. No ongoing fee unless you choose to continue with another service afterward.

What's included

  • — Written report covering consumption by system and hour band
  • — A list of adjustments worth examining
  • — Use of existing utility and sub-meter data — no new hardware required

THE PROOF

How the reading holds up

The method relies on data your building already produces, cross-checked across the billing period under review. Confidence in each figure is stated alongside it, and a realistic timeline — three weeks from records received to report delivered — is set at the outset rather than promised loosely.

THE GUARANTEE

A no-obligation first conversation

Before any engagement begins, we're glad to talk through what data you have and whether this analysis is the right fit. If your building's records are too limited to support it, we'll say so rather than proceed regardless.

NEXT STEPS

Getting started is a short first step

Send a note describing your building and what records you have on hand. We'll confirm what's needed and roughly when the report could be ready.
