Building Energy Optimization with ROOMSYS
Your building has a grade. Do you know what it is? In the U.S., both commercial and multi-family residential properties are now rated from A to F based on their energy efficiency. These scores, along with ENERGY STAR® scores, are used by regulators, utility companies, and tenants to evaluate building performance and compliance. A low score means higher energy bills, increased scrutiny, and declining asset value. ROOMSYS provides a fast, practical way to boost your score and reduce energy waste.
Our plug-and-play system combines remote-control thermostats, smart power metering, and a real-time dashboard that identifies energy loss and enables targeted action. Complete visibility, precise control, and measurable savings, built in every level of your operation.

Centralized Energy Management Across Utilities
Managing utilities shouldn’t require juggling several platforms or relying on manual tracking. ROOMSYS is an all-in-one platform that integrates HVAC, power, and water monitoring into a single, united interface. It helps lower your energy bills, reduce operational waste, and improve your building’s A–F energy rating or ENERGY STAR® score through real-time control and automation.
ROOMSYS Energy Dashboard for Real-Time Building Monitoring
Get a complete, interactive view of how energy is used throughout your facility, floor by floor, room by room. The ROOMSYS dashboard turns complex data into clear, actionable insights that help you cut waste and improve system efficiency in real time.Energy Monitoring and Control with ROOMSYS App

How ROOMSYS Energy Optimization System Works
ROOMSYS creates a closed-loop energy optimization environment by combining sensors, secure wireless connectivity, and intelligent cloud analytics.
Multi-device integration
ROOMSYS works with thermostats and electrical sub-meters from trusted manufacturers.
Sensor input
Each device collects targeted data, including temperature, occupancy, humidity, power consumption, and system pressure.
LoRaWAN gateway
Ensures reliable, long-range data transmission from devices to the cloud with minimal power usage. It is ideal for large or multi-floor buildings.
ROOMSYS cloud platform
Aggregates and analyzes all incoming data, automates HVAC and lighting behavior, detects inefficiencies, and generates actionable alerts.
Dashboard & mobile app
Provides a real-time view of building energy usage, system performance, and environmental conditions, enabling remote control, reporting, and scheduling from a single interface.
Why Property Owners Choose ROOMSYS for Building Energy Optimization
ROOMSYS gives property owners and facility managers complete visibility into how energy is consumed plus the tools to improve it. Our wireless, all-in-one system integrates smart thermostats, power meters, and environmental sensors to provide centralized, automated control without major retrofits or rewiring.
The platform:
- Reduces operating costs through intelligent, data-driven energy management;
- Enables compliance with local energy codes, benchmarking ordinances, and carbon emission laws (e.g., NYC Local Law 97);
- Uses live sensor data to dynamically adjust HVAC and power systems based on real occupancy and demand;
- Minimizes peak loads, idle system runtime, and utility waste;
- Extends equipment life by reducing overuse and thermal strain.
