Hotel edition · November 2026

The building
already knows.
It just isn’t
listening.

A 200-key hotel at ₹11.50 a unit spends about ₹5.3 crore a year on electricity. This is what happens when every room reports back — and what that is worth.

Proposal · hotels

Prepared for the general manager and chief engineer of a 200-key hotel. Figures are modelled for a representative property and replaced by your meters in the first two weeks.

01 — The bill

₹5.3 crore a year. Most of it invisible.

A hotel doesn’t waste energy in one place. It wastes it a room at a time, a chiller-hour at a time — and none of it shows up until the bill.

₹11.50

per unit all-in: ₹9.40 energy, ₹608/kVA demand, 5% tax — an industrial-tariff number. A Maharashtra commercial connection is about ₹19.70.

94 kWh

per occupied room-night, including the hotel’s share of plant and public areas.

58%

of that bill is air-conditioning — rooms and chillers. Start there, or don’t start.

34% Guest rooms
24% Chillers & plant
17% Kitchens & laundry
15% Public areas
10% Everything else

What the hotel already does

None of this is broken. It is just not per room.

  • Key card at the doorPower cuts when the card is pulled — but guests leave a spare in the slot, and half the rooms get bypassed.
  • Manual thermostatThe guest sets 18°C and the room runs there all night.
  • Chillers on a timetableSet when the building opened. They still start and stop at the same hours whether the hotel is full or a third empty.
  • Housekeeping by phoneRoom status is a phone call, not a signal.

02 — The saving

Where the 20% comes from.

The full programme: ten changes, 20 points at the top of the credible range. Rooms alone are 5–10 points; if you stop there, plan on 10–15%.

How we know a room is empty

mmWave radar, not PIR. PIR reacts to movement and can be fooled by a warm draft — a guest reading in a chair or asleep drops off it, and the room gets cooled for nobody. mmWave holds a still person, works in the dark, sits behind a plastic panel and has no lens.

All ten are kilowatt-hours. Demand-charge reduction and moving laundry off the peak are worth money too — deliberately not counted, so the model can only under-promise.

The market

How it works now.
What we offer. Why we’re better.

What a 200-key hotel can buy today — a building system, a room controller, an energy dashboard, a wireless retrofit — what each costs over five years, and where our overlay fits. The full landscape and sources are at the bottom.

01 — How it works now

Building system (BMS)

₹6.4–8.8 croreover five years, 200 keys

  • Runs the plant well
  • No room, booking or guest layer
  • 12–24 months to deliver
  • You pay for every point and licence

Best if you are building new and the operator names the vendor.

Room controller

₹1.8–5.8 crorefive years · midscale to luxury · 200 keys

  • Rooms only
  • No plant view
  • No proof of the saving
  • Priced per room

Best if the rooms are the only gap and the plant is already covered.

Ambient Form

₹1.7–2.7 croreover five years, 200 keys

  • Room + plant + booking + report
  • Floor by floor, no shutdown
  • No licence for every sensor
  • The hotel owns the system

Best if you need the bill to move and you want to keep the plant.

Why us, in one line: the only one that connects the booking, the room and the bill — for about a third of a building-system programme, with the room, the booking link and the report included.

02 — What we offer

An overlay on the plant you already have: per-room control, a booking-system link, a meter reading and a monthly report. No per-point licence; floor by floor; the hotel owns the hardware, the data and the automations.

Capex plus five years of AMC or licences. Planning bands, not quotes. A BMS is priced per point, a GRMS per room, SaaS per room per month. The calculator below divides by key.

03 — Why we’re better

01

No per-point licence.

Adding a meter or a room is a configuration, not a variation order. The hub is bought once.

02

Keep the plant and its warranty.

We read and write where the building system allows it. The chiller, the fire system and the plant contractor’s warranty stay untouched.

03

The hotel owns the loop.

Room, booking, meter and report in one system. The data stays on the property, and the report is tied to the bill.

The same scope, priced

200

200 keys · plant, rooms and one report

One key is one room. Public areas, kitchens, laundry and the plant add load, but the capex here is the room and integration layer, not a chiller replacement.

BMS-led overlay per point

Indicative capex₹2.8–5.2 crore

Running: ₹72 lakh a year

Five-year cost ₹7.6 crore

  • Plant, meters, alarms and trends
  • Sequenced plant and warranty

  • Per-point licence and a 12–24 month project
Luxury GRMS / KNX per room

Indicative capex₹2.2–3.6 crore

Midscale GRMS per room

Indicative capex₹98 lakh–1.6 crore

Running: ₹16 lakh a year

Five-year cost ₹2.1 crore

  • The workhorse: card switch, thermostat, panel
  • Lower capex, local supplier
  • Little or no analytics, no plant view
  • Hard to prove the saving
Ambient Form room to report

Indicative capex₹1.2–2.2 crore

Running: ₹10 lakh a year

Five-year cost ₹2.2 crore

  • Room control, PMS link, meter, report
  • Plant stays; floor-by-floor retrofit
  • No per-point licence; hotel owns it
  • 10–18% saving, metered against a baseline

Indicative only. The BMS band assumes a 200-key overlay with plant integration; the GRMS bands use converted turnkey benchmarks, not Indian quotes. The five-year cost includes AMC at 18% (BMS), 15% (luxury GRMS), 12% (midscale) and an optional 6% support plan for ours. A wireless kit at ₹15,000–27,500 a room is cheaper than all four — and does none of the integration. We are not the cheapest per key; we are the cheapest way to close the loop.

03 — Scope

What we automate.

One layer runs the building in states — occupied, vacant, arriving, servicing. One layer knows which state it is actually in.

Occupancy cooling

mmWave radar knows empty from still. Setback when it’s empty, the guest’s setpoint when it isn’t.

Pre-arrival from the PMS

Cool 40 minutes before check-in, not all morning.

Check-out reset

AC, lights, TV and curtains reset in one event.

Shade before the sun

Blinds close ahead of direct sun and open after it.

Doors, windows, bathrooms

AC pauses on an open balcony door. Exhaust follows humidity.

Housekeeping status

Occupied, ready, service or DND — from the room, not a call.

Already in the building and already speaking: PMS, BMS, access control, CCTV, energy meters, chillers, AHUs, pumps, lifts, laundry, kitchen exhaust, water and STP.

04 — The unit

One room, three states.

The whole proposal at its smallest. Change the state and watch what the room does.

What triggered it

Door contact open, three minutes. mmWave confirms one person.

What the system did

Held the guest’s setpoint. No setback while someone is in the room.

What it costs

About ₹350 for the day at ₹11.50 a unit. A fixed 22°C room would be ₹442.

26.5°C

the setpoint of an empty room — the single biggest number here

~35%

off room cooling in the model — a third, not the 81% an empty room shows

₹63 lakh

a year from the rooms alone, before plant or public areas

Why 35% and not 81%: not every room is empty at once, and key cards already do some of this. We model the conservative average, then measure the real one.

05 — The money

What it’s worth.

A 200-key hotel at your tariff. The default ₹11.50 is an industrial rate; a Maharashtra commercial connection is closer to ₹19.70. Move the sliders; the audit replaces every number with yours.

₹11.50 is an industrial rate. Commercial Maharashtra is about ₹19.70; set this to your bill.

The ten changes behind it

Grid factor 0.71 kgCO₂e/kWh. Excludes demand-charge reduction and maintenance savings, which are upside.

Read the model’s assumptions
Room energy
32 kWh per occupied room-night: a 1.5 TR inverter unit at about 1.3 kW average, plus lighting, TV and plugs.
Shared energy
42 kWh per key per night for public areas, kitchens, laundry, pumping and plant.
Tariff
₹9.40/unit, ₹608/kVA/month demand, 5% electricity tax — about ₹11.50 all-in. That is an industrial-tariff number; a Maharashtra commercial connection is about ₹19.70. We re-price it at your bill in the audit.
Savings
10% low, 15% rooms-only, 20% full programme, against a hotel with key cards and manual thermostats. The 20% needs the plant and lighting measures, not just room controls.
Capex
Planning bands, not a quote. Hardware at actuals, vendor-neutral, itemised before approval.

Roughly 7% of revenue at this bill — inside the 4–8% range for Indian hotels, at the top of it because of the cooling load. A commercial tariff pushes the bill, and the ratio, higher.

Three things to check

A 1–2 year payback is unusual. It needs the full 20% programme and an industrial tariff; at 15% it is 1.5–2.8 years. Check these before believing any of it.

  1. 01
    The baseline

    If key cards already work in every room, room savings shrink. The audit measures your rooms, not the model.

  2. 02
    The tariff

    ₹11.50 is industrial. Commercial Maharashtra is about ₹19.70, which makes the same saving worth more; a lower industrial rate makes it worth less. The bill decides.

  3. 03
    Comfort

    Savings from a warmer room don’t count. Temperature excursions are reported next to the savings, every month.

06 — The data

Days to understand.
Months to compound.

The first findings arrive inside a week. The model keeps improving after that. You don’t wait a year for the first answer.

  1. 01

    Instrument

    Every room, panel, pump and tank. A few thousand readings a minute. Stored locally.

  2. 02

    Baseline

    Peer comparison is ready on day three: room 512 against the fourteen rooms beside it.

  3. 03

    Detect

    A room at twice its neighbours’ load. A chiller losing COP. A pump starting harder.

  4. 04

    Predict

    Booking pace, arrivals and weather become a 72-hour forecast. Cool the floors you will sell.

  1. Day 1

    Rooms come online. Every room is compared with every other room.

  2. Day 3

    The first anomaly list — which rooms are above and below their peers.

  3. Week 2

    The first plant drift: a chiller, pump or AHU against its own past.

  4. Month 1

    The first measured report, against the baseline you agreed.

  5. Month 3

    Summer and monsoon behaviour modelled. The system starts predicting.

What the first week produces

Room peer rooms room 412

Valve stuck open

Banquet cooled too early

Four hours became 45 minutes. About 40 kWh an event.

Measurement

How we prove it

Savings claims are where these projects lose credibility. Ours are reported the boring way.

  • A weather-normalised baseline agreed before switch-on (IPMVP Option C).
  • Avoided kWh and rupees per floor, outlet and plant item.
  • Temperature excursions and complaints next to the savings. Savings from discomfort don’t count.
  • The months that miss are published too.
On premise

The historian and the models run in the building.

DPDP Act 2023

Consent, retention limits, a named grievance contact.

No lens, no ears

No cameras or microphones in guest rooms. Ever.

Room IDs, not names

Guest identity stays in the PMS.

07 — At scale

Not two hundred apps.

Rooms report to floors, floors to one local server, the server to the people who need it. Every layer fails gracefully.

Local-first

If the internet drops, rooms keep running on local schedules.

Fail-safe

If the server dies, each floor falls back to its own schedule.

Segmented

Guest Wi-Fi, rooms, CCTV and BMS on separate VLANs. No inbound ports.

Open

MQTT, Modbus, BACnet, KNX. Exportable data, documented design.

Retrofit without closing a floor: ninety minutes a room, in vacant inventory, one floor at a time. Sellable the same night.

08 — Rollout

Four phases. Four gates.

Nothing scales until the pilot proves itself on your numbers, not ours.

  1. 01Week 0–2

    Metered audit

    Clamp meters, fourteen days of data, tariff and room survey. No hardware bought.

    You see the numbers before committing.

  2. 02Week 3–8

    Pilot floor

    Twenty keys. Controls, sensors, housekeeping board, six weeks of measured results.

    No guest complaint; at least 15% on the floor.

  3. 03Week 9–20

    Guest wings

    Floor by floor, a room at a time. Commissioning sign-off before the next floor.

    Every floor signed off before the next.

  4. 04Week 12 onward

    Plant, then operate

    Chillers, AHUs, kitchen exhaust and public areas. Then monthly tuning and M&V.

    Comfort verified at the guest end, not the plant.

09 — Guardrails

What we won’t do.

A pitch is a list of promises. These four don’t move, even when moving them would make the numbers look better.

Won’t touch life safety

Fire, lifts and emergency lighting stay with certified systems. We read from them.

Won’t trade comfort

If a room is warm when the guest walks in, the saving doesn’t count.

Won’t claim what we can’t measure

Every number sits against a weather-normalised baseline. Bad months included.

Won’t rent you your building

The local system runs without us. Data exports. Docs are yours.

The team

We built this for a home.
A hotel is the same job, repeated.

We’re a studio that designs interiors and automation together, running a live local-first system every day. We’re not a BMS major, and we won’t pretend to be. What transfers is the discipline; the plant, the union and the guest promise we learn from you. The pilot is how, at one floor’s risk.

The full competitive market, priced

10 — Questions

The questions that follow the price.

What does it cost?

₹1.2–2.2 crore for a 200-key retrofit, including hardware and commissioning, excluding civil work and GST. At the next AC or BMS replacement the marginal cost is roughly half. The audit fee is fixed and credited against implementation.

How disruptive is it?

Ninety minutes a room, in vacant inventory, nine to five, one floor at a time. No floor closes. Plant work happens in low-occupancy windows.

Do we have to replace the air-conditioners?

No. Controllers and gateways work with existing splits and FCUs through IR, Modbus or dry contacts. We audit before recommending anything.

Will it work with our PMS and BMS?

Reservations and arrivals come from the PMS API; plant data from the BMS over BACnet or Modbus. If the BMS can’t expose a reading, we clamp a meter at the panel.

Who maintains it?

Your engineering team, with a dashboard, training and a runbook. We can retain for monthly tuning and on-site support. The system is open, so you aren’t stuck with us.

What if the internet goes down?

Nothing a guest would notice. Control and schedules run on the local server; only remote dashboards pause.

What about guest data?

Analytics run on room numbers against anonymous profiles. No cameras or microphones in rooms. Held on site under the DPDP Act, never resold.

What’s the catch?

Time and access. A baseline needs a fortnight, installs need vacant rooms, and somebody on your side has to own the number. If those aren’t available, this doesn’t work — and we’ll say so in the first meeting.

Next

Start with the meter,
not the pitch.

Two weeks. The mains, the plant and one floor. You get a baseline from your own numbers and a pilot plan you can approve or bin. If the case isn’t there, you hear it before you buy hardware.

The full competitive landscape
01 ₹2.8–5.2 crore
200 keys

The BMS major.

Chiller plant, AHUs, pumps, towers, meters, alarms and trends, on BACnet or Modbus. The right tool for a central plant, and the only segment that will sequence it properly.

What you get
Dense I/O, plant sequencing, alarm history, cybersecurity hardening, commissioning and a warranty.
Where it stops
No guest-room UX, no keypads, no PMS logic. Licensed per point or seat. Delivered by a certified integrator, so a setpoint change becomes a purchase order.

Names you’ll meet: Schneider EcoStruxure, Siemens Desigo, Honeywell, Johnson Controls, Delta Controls; Indian challengers such as EnSmart.

02 ₹87.5k–2.5L
a room

The luxury GRMS.

A room controller, keypad, occupancy sensing and a thermostat that sets back when the room is empty. INNCOM, Schneider’s room controllers, Lutron, Crestron and KNX all play here.

What you get
Room scenes, keycard/PIR logic, DND/MUR, curtains and a PMS link if you pay for it.
Where it stops
No plant control, no chiller optimisation, no portfolio analytics. Proprietary unless KNX or Modbus. Per-room hardware and programming.

Names you’ll meet: Honeywell INNCOM, Schneider SpaceLogic, Lutron Hospitality, Crestron, Control4, KNX vendors.

03 ₹35k–75k
a room

The midscale GRMS.

The same idea at a lower price: a wired room controller, card switch, thermostat and a few panels. The workhorse of midscale Indian hotels, and the honest comparator for our price.

What you get
Occupancy setback, keycard control, a few scenes, a local supplier and a standard warranty.
Where it stops
Little or no analytics, no PMS-driven pre-cooling, no plant view. The room saves energy, but nobody can prove how much or why.

Names you’ll meet: INNCOM, Legrand/Bticino, Indian RCU and panel vendors, regional ELV integrators.

04 €4.99
a room a month

The energy dashboard.

Meters, bill audit, benchmarking, alerts and measurement and verification. Useful, and often the fastest way to find the leak. But it is a report, not a control system.

What you get
Visibility, exception alerts, a monthly number and an evidence trail for the owner.
Where it stops
Mostly read-only. It can tell you the plant is drifting; it cannot reset the setpoint, cool the arriving room or turn off the AC after checkout.

Names you’ll meet: Schneider Resource Advisor, Zenatix (now Schneider Electric), Hatch, Enertiv, Aquicore, Sens.

05 ₹15k–27.5k
a room

The wireless retrofit.

BLE mesh panels, a card switch, a thermostat and a PIR, installed room by room. Cheap, fast, and reversible. The hotel keeps its wiring and its plant.

What you get
A room that sets back when empty, without opening a wall or shutting a floor.
Where it stops
No PMS integration, no plant view, no M&V, no report. A pile of rooms that save something, with no way to prove it.

Names you’ll meet: BLE Mesh and Zigbee vendors, regional retrofit firms, Home Assistant installers, online hardware sellers.

06 ₹60k–1.1L a key
₹1.2–2.2 crore for 200

Ambient Form: the overlay that closes the loop.

Keep the plant and its warranty. Add per-room control, a PMS link, a meter reading and a report that reconciles the three. One local hub per property, not a server per floor. The hotel owns the hardware, the data and the automations.

What we replace
The gap between the BMS, the room controller and the dashboard. Not the BMS itself, and not the chiller.
What we keep
Your plant, your PMS, your locks, your network where it is sound. We add the layer that reads and acts.
Where it stops
Life-safety stays certified. A new-build 300-key with brand standards may want a single BMS contract. See the limits.

What we don’t sell: a per-point licence, a 12-month shutdown, a proprietary server, or a saving we cannot meter.

How the ranges were built. BMS has no published India list price; the ₹2,500–6,000 per point range and the 3–4× quote spread come from an Indian BMS integrator’s 2026 cost guide. GRMS per-room bands are converted 2026 China turnkey benchmarks, labelled as such, with 20–40% added for Indian duty, labour and hotel hours. The luxury band is ₹87,500–2,50,000 a room; midscale is ₹35,000–75,000. The tariff is MERC Case 75/2025 and MSEDCL’s FY27 schedule; the all-in figure assumes 900 kVA and 4.6 GWh, and the actual duty and ToD on the bill will move it. Savings ranges are built from the cited shares and case studies. A metered audit replaces all of it. Nothing here is a quote.

Figures are indicative, not a quote. A firm is named only where it has published a price.
