A 250-room hotel wasting 30% of room energy is burning €60,000 a year. The iNELS HRESK kit pays back in 18 months.
iNELS HRESK (Hotel Room Energy Saving Kit) is a rapid-deploy package — key card holder, presence sensor, room controller — that cuts room energy without replacing your existing systems.
The hotel energy ROI problem
Hotels want to cut energy but cannot afford long payback periods or disruptive installation. HRESK was designed to deliver measurable ROI with minimal disruption to operations.
High per-room energy cost
Climate and lighting left running between guests and during long guest absences drives 30-40% waste.
Existing infrastructure cannot be replaced
Full room replacement is not feasible during operation. The solution must work with what is already installed.
Long payback periods deter investment
Hotel owners need to see ROI within 2 years to justify the capital expenditure.
The fastest ROI in hotel energy management
The HRESK kit installs in under 2 hours per room, works with existing systems, and starts delivering savings from day one.
Key Card Holder Energy Cut-off
All non-essential loads cut when the guest removes their key card — zero energy waste between stays.
Presence Sensor for Climate Setback
Room climate returns to setback temperature within minutes of the guest leaving.
Retrofit — No New Wiring
HRESK components fit into existing room infrastructure — no rewiring, no downtime.
Central Energy Reporting
Per-room energy data aggregated to a central dashboard for management reporting.
