Service · Energy Audit · Law 21.305 · Consumption Reduction
We audit your HVAC system's real consumption, identify inefficiencies, and implement improvements that reduce electricity use 20–40% — with documented ROI and Law 21.305 compliance support.
What we do
Full survey of all HVAC equipment: real consumption measurement (kWh/month per unit), operating schedule analysis, setpoint vs. actual temperature, and maintenance status. We deliver a report establishing the energy baseline and identifying the highest-waste points in the system.
Error log and operational data read-out via manufacturer software (Daikin D-Checker, Mitsubishi PAC-SIF, LG LGAP). We identify inefficient operating modes, mis-calibrated expansion valves, refrigerant leaks, and dirty or degraded outdoor-unit fans that can increase consumption by 10–30%.
For each measure identified in the audit: description, required investment, estimated savings in kWh/year and CLP at current electricity rates, simple and discounted payback, and CO₂ emission reduction. All projections use actual Chilean tariff rates (BT-1 > $170 CLP/kWh in 2025).
We carry out the improvements found in the audit: heat exchanger cleaning, refrigerant recharge, replacement with high-efficiency controllers, VFD installation on AHU motors and cooling towers, and setpoint and schedule updates in the BMS.
We install energy sub-meters on HVAC circuits to verify actual savings after improvements. Monthly M&V reports are delivered per the IPMVP protocol (International Performance Measurement and Verification Protocol) — accepted by insurers and green finance institutions for savings accreditation.
Advisory for companies consuming more than 50 TOE/year: Energy Management System (SGE, ISO 50001-aligned) implementation, Energy Consumption Report (RCE) for the Ministry of Energy, and Energy Management Programs (PGE) with the HVAC baseline. Penalties for non-compliance reach 500 UTM.

FAQ
A VRF system installed more than 5 years ago without proper maintenance can be consuming 20–40% more than it should. The most common causes: dirty filters (reduces airflow, forces the compressor to work longer), dirty outdoor unit heat exchanger (raises condensing temperature +3–5°C — equivalent to +10–15% consumption), refrigerant leaks, and setpoints set too low for actual use. Fixing these costs a fraction of equipment replacement.
Chile's Energy Efficiency Act (Law 21.305, enacted 2021) establishes obligations for "large energy consumers" — companies with annual consumption above 50 TOE (tonnes of oil equivalent, roughly 580,000 kWh/year of electricity). These companies must: implement an Energy Management System (SGE, ISO 50001-alignable), report annual energy consumption to the Ministry of Energy (RCE), and set Energy Management Programs (PGE). Non-compliance penalties reach 500 UTM (≈ CLP 30M / USD 32K in 2025). International companies with Chilean facilities are subject to the same requirements.
An ASHRAE Level 1 audit (site walk-through, invoice review, low-cost measure identification) for a 1,000–5,000 m² building costs UF (Unidad de Fomento, Chile's inflation-indexed unit, ≈ USD 33 in 2025) 20–60. A Level 2 audit (per-equipment consumption measurement, detailed analysis, savings projections) for the same size costs UF 60–150. For buildings over 10,000 m² or industrial operations, cost is quoted based on number of systems and equipment.
In comfort HVAC (offices, hotels, retail), high-efficiency VRF systems (inverter, EER/COP > 4.5) consume up to 40% less than constant-speed equivalents. In commercial refrigeration, the biggest lever is migrating to low-GWP refrigerants with electronic expansion valve controllers and centralized monitoring. For chilled water systems, VFD installation on compressors and pumps typically cuts consumption 25–50% at partial loads.
Low-cost measures (equipment cleaning, setpoint correction, schedule adjustments): immediate payback — no significant investment, only labor cost. Mid-range investments (refrigerant recharge, controller replacement, motor VFDs): typical payback 1–3 years. Equipment replacement (new high-efficiency VRF): 4–8 years depending on energy price and usage profile. At Chile's current commercial electricity rate (BT-1 tariff, >$170 CLP/kWh), efficiency projects are highly attractive financially.
