Voltic helps you cut consumption, measure it, and start a serious conversation about the economic value of efficiency. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- [ Request a demo](/en/demo) [ Estimate potential ](/en/forms/estudio) No inflated promises: the money depends on certified savings, the agreed price, and whether the measure meets CAE system requirements. ![Voltic kit for measuring and automating hotel room energy consumption](https://voltic.es/cdn-cgi/image/format=auto,quality=82/https://cdn.voltic.es/media/partners/voltc-team.jpg) Quick answer What is a CAE and why should a hotel care? -------------------------------------------- A CAE is an electronic certificate that makes a measured amount of energy savings official: 1 CAE equals 1 kWh/year of certified savings. For a hotel, the key idea is simple: if a measure reduces consumption in an eligible, documentable, and verifiable way, that saving may have market value through an agreement with an obligated or delegated party. [ See Voltic demo](/en/demo) [ Request energy study ](/en/forms/estudio) 1 CAE Equals 1 certified kWh/year The minimum unit for buying, selling, and settling in the system is the annual certified saving. €/CAE Market-defined price The final amount is not fixed: it is agreed in the contract and depends on demand, volume, and the quality of the file. 3 years Settlement window A CAE can be settled against savings obligations during the three years after the measure is completed. The money part Economic value comes from the savings you can certify ----------------------------------------------------- The system does not pay for installing technology. It pays for proving energy savings under CAE rules. certified kWh/year x agreed €/CAE price = potential savings value The consideration is defined in a CAE agreement. It is not a subsidy and is not subject to state aid rules under the framework described for energy saving beneficiaries. ### More measurable savings, stronger economics The main variable is the annual certified savings volume. That is why measuring before and after matters. ### Voltic does not set the price The €/CAE price is defined by the market and by agreement with the obligated or delegated party. The file should be evaluated before promising amounts. ### Documentation protects value Photos, technical data, investment evidence, traceability, and verification reduce friction and make the saving easier to defend. ### Cut consumption where it hurts. In hotels, rooms concentrate many energy leaks: HVAC running without occupancy, open windows with air conditioning on, and no mass control. ![Ilustración de Cut consumption where it hurts.](https://voltic.es/cdn-cgi/image/format=auto,quality=85/https://cdn.voltic.es/media/_draft/frame-demo4.png) ### Measure so savings can be defended. Voltic provides operational, occupancy, window, temperature, and usage data to understand real consumption and prepare a more traceable file. ![Ilustración de Measure so savings can be defended.](https://voltic.es/cdn-cgi/image/format=auto,quality=85/https://cdn.voltic.es/media/_draft/man-movile-app.png) ### Install without stopping the hotel. A modular rollout lets you act room by room, without invasive works or bus wiring, and prioritize areas with higher savings potential. ![Ilustración de Install without stopping the hotel.](https://voltic.es/cdn-cgi/image/format=auto,quality=85/https://cdn.voltic.es/media/_draft/voltic-kit-front.png) ### Move from efficiency to a financial conversation. A demo does not replace CAE verification, but it helps estimate whether the project has enough savings, data, and documentation to move forward. [ Request a demo ](/en/demo) ![Ilustración de Move from efficiency to a financial conversation.](https://voltic.es/cdn-cgi/image/format=auto,quality=85/https://cdn.voltic.es/media/landing/obligatorio2026/hand-eventos.png) How a CAE flows From room savings to a certificate that can be settled ------------------------------------------------------ The CAE process clearly separates who generates the saving, who verifies it, and who uses it to meet energy obligations. 1. 1 ### Efficiency measure The hotel executes an improvement that reduces energy consumption, such as smart HVAC and occupancy control. 2. 2 ### Measurement and documentation Data is collected on the measure, investment, equipment, baseline, and evidence required by the applicable sheet or methodology. 3. 3 ### CAE agreement The original owner of the saving transfers that saving to an obligated or delegated party in exchange for economic consideration. 4. 4 ### Independent verification An ENAC-accredited verifier issues an opinion on the conformity of the measure and the savings achieved. 5. 5 ### Issuance, trading, and settlement The regional manager issues the CAE and the obligated or delegated party may buy, sell, or settle it against its obligations. Not every saving automatically turns into money ----------------------------------------------- Economic potential exists when the project fits the CAE framework and the file can be verified. ### Standardized measure It fits a catalogue sheet. The calculation method is already validated and verification is usually simpler, shorter, and cheaper. - There is an applicable sheet. - The calculation formula is already defined. - The required documentation is clear from the start. ### Singular measure Used when a standard sheet is not enough and the savings volume justifies a specific technical calculation. - It can calculate savings more precisely. - It usually fits higher-volume projects. - Verification is longer, more technical, and more expensive. ### Documents and data that can make the difference Previous consumption or a defendable baseline. Equipment data, serial numbers, photos, and location. Budget, investment, and execution evidence. Operational records after the measure. Evidence that the saving is not renewable generation without countable savings. The demo should answer a financial question ------------------------------------------- Is there enough measurable and documentable saving to make starting a CAE file worthwhile? ### We detect waste points Empty rooms, open windows, extreme setpoints, and hours where HVAC consumes energy without adding value. ### We estimate savings and traceability We review which data can be captured and which part of the saving can be defended with evidence. ### We prioritize rollout If the potential exists, we propose a phased measure so investment and promises stay realistic. ![](https://voltic.es/cdn-cgi/image/format=auto,quality=80/https://cdn.voltic.es/media/_draft/voltic-kit-bg.png)### Voltic + CAE Hotel automation with data to evaluate certifiable savings. [ Request a demo ](/en/demo) - Occupancy and open-window HVAC control - Operational data to understand savings - Modular rollout without invasive works - A basis for estimating whether CAE is worth pursuing CAE issuance always requires eligibility, documentation, and independent verification. Common questions about CAEs --------------------------- How much money can a hotel receive through CAE? There is no universal figure. It depends on certified kWh/year, the agreed CAE price, management and verification costs, and whether the measure is eligible. The responsible starting point is to calculate defendable savings before discussing amounts. Who pays the consideration? It is usually agreed with an obligated or delegated party through a CAE agreement. The hotel, as the original owner of the saving if it executed the investment, transfers that saving in exchange for consideration. Is it a subsidy? No. The CAE system documentation describes it as consideration defined in a private agreement for transferring savings, not as a subsidy. Can Voltic issue the CAE? Voltic helps reduce consumption, generate data, and prepare the potential analysis. Verification belongs to an accredited verifier and issuance belongs to the regional manager within the CAE system. Does it work if I already installed an efficiency measure? It can depend on timing, available documentation, the agreement, and the measure requirements. If baseline, execution, or savings evidence is missing, economic value may be reduced or lost. Why request a Voltic demo to talk about CAE? Because before selling a file, you need to find real savings. The demo shows how Voltic controls HVAC, occupancy, and windows, and which data can help estimate monetizable savings.
