Hotel guest rooms demand a delicate balance: guests expect personalized comfort and fresh air, while operators aim to reduce HVAC energy costs and comply with evolving sustainability standards. Yet most guest rooms operate on fixed cooling schedules, regardless of occupancy or air quality, leading to energy waste, thermal discomfort, and non-compliance with indoor air standards.
Sol-In solves this challenge with a data-driven, guest-friendly approach. Our AI-powered platform integrates occupancy-aware ventilation, IAQ monitoring, and smart FCU control to deliver optimal comfort when guests are present – and significant energy savings when they’re not.
In hotels, HVAC systems often run continuously – cooling guest rooms, lobbies, dining halls, and other shared spaces even when occupancy is low. Air handling units (AHUs) and fan coil units (FCUs) are typically operated at constant flow rates, regardless of real demand, resulting in energy waste, over-ventilation, and excessive wear on systems.
Sol-In’s platform introduces intelligent, demand-based ventilation (DCV) for the entire property: from guest rooms to multi-story lobbies, dining rooms, gyms, and spa facilities. By combining real-time occupancy data with indoor air quality (IAQ) monitoring, the system dynamically adjusts airflow, temperature, and fresh air intake in every zone.
During low-occupancy hours, ventilation and cooling are automatically optimized for efficiency; as guest activity increases, the system restores ideal comfort and air quality. This unified approach enables up to 50-60% energy savings while maintaining healthy, comfortable conditions across both private and public spaces, improving the guest experience and the hotel’s bottom line.
Sol-In makes it easy to scale across 100+ room hotels and public areas by integrating with both FCUs and AHUs. Our platform supports LEED, WELL, RESET, ASHRAE, and Israel’s 5281 standards, with full MRV (Measurement, Reporting, and Verification) capabilities. That means easier compliance, better ESG reporting, and real operational savings you can show.
From boutique hotels to large resorts, Sol-In transforms your indoor environment into a high-performance hospitality experience – intelligently, automatically, and invisibly.
