Energy Optimization for Indoor Farms

We model where your energy goes before a single unit is bought.

01

Where the Energy Actually Goes

In a plant factory, lighting and air conditioning together account for roughly 82.5% of total energy use — the figure most feasibility studies underestimate, and the figure every OPEX model has to get right first. Within that, lighting alone can be 70–80% of total electricity. Electricity and climate control together commonly drive 60–80% of operating cost.

02 Lighting Side

Specify light to the crop, not the room

PPFD and DLI designed to the crop — light the canopy at the intensity each species actually uses, not a flat "watts per square metre".
Spectrum chosen for the goal — vegetative growth, quality or morphology, matched to the crop and the stage.
Zoning, staging and dimming — fewer, better-placed fixtures at the right height, so you pay only for the light the crop can use.
DC distribution where it pays — research shows DC distribution can remove the per-fixture rectifier/PFC stage and simplify drivers, cutting a real layer of conversion loss.

03 HVAC Side

Size HVAC to the actual load, not a guess

Sensible, latent, ventilation and envelope loads calculated separately — dehumidification sized to real latent load, not an oversized unit.

Dehumidification as part of the energy picture — latent load is a major, often-missed driver of total power.

Heat recovery where it pays — recovered heat offsets heating demand instead of being exhausted to waste.

Thermal storage and off-peak charging — ground-source heat pump with water thermal storage (charge at off-peak tariff, discharge at peak) is one of the routes we evaluate where the site and tariffs justify it.

04 Control Side

Control strategies that cut peak demand

Time-of-use scheduling — shift loads that can move, avoid running everything at peak tariff.

Peak shaving and staged start-up — sequence equipment so start-up surges do not stack.

Variable-speed and demand-based operation — fans, pumps and chillers run to need, not flat-out.

05 Energy-Saving Technology Routes

The routes we evaluate, on paper first

We do not sell a single "energy saving" gadget. We assemble a site-specific menu of documented routes and model each one against your crop, climate and tariffs:

Envelope & scheduling — high-reflectance, low-ventilation envelope; running the dark period during daytime to use cooler outdoor air (research reports savings up to 23.9% under studied conditions).
Light side — dynamic intensity control, demand-based lighting, DC distribution.
HVAC side — ground-source heat pump + water thermal storage; phase-change envelope with metal-foam heat transfer enhancement.
System side — integrated light–climate–nutrient–humidity control driven by a crop database; PV + wind microgrid for remote sites.
Architectural side — energy-led building design for vertical farms.

06 What We Deliver

An energy and OPEX model, before you commit

For each project we build a site-specific energy model — lighting, HVAC, dehumidification, pumps and controls — and turn it into an OPEX picture you can take to investors and lenders.

FAQ.

Q: Can you guarantee a specific kWh per kg?

A: No — and we would be wary of anyone who does. Energy per kg depends on crop, location, climate, electricity price and operational discipline. What we do is model it transparently and reduce it structurally.

Q: Where do most farms waste energy?

A: In three places: lighting that over-delivers or is poorly placed, HVAC sized by guesswork, and equipment run flat-out when it does not need to be.

Q: Does energy optimization add cost up front?

A: It changes how the money is spent, not how much is spent overall. The model usually shows the extra engineering cost being recovered through lower operating cost.

Q: Do all those "technology routes" apply to my project?

A: No. Each route is evaluated against your crop, climate and tariff. Some pay back immediately; others only make sense at a certain scale or location. The model shows which.
