What It Is

HEBES Intelligence’s Meval is an advanced measurement and verification (M&V) tool for energy-efficiency retrofits in building HVAC systems. It is not a conventional marketing or SEO product; instead, it is designed for building energy analysis, retrofit validation, and operational performance monitoring. The product emphasizes combining predictive models with physical models to prove energy savings, maximize retrofit ROI, and meet regulatory or stakeholder requirements for verified savings outcomes.

Core Capabilities

Based on the main content, Meval’s key differentiator is that it does not reduce M&V to a simple prediction task. It uses pre- and post-retrofit data, weather conditions, calendar features, sensor and meter data to estimate indoor activity levels in buildings, and decomposes changes in energy savings into causal pathways such as “efficiency upgrades” and “activity changes.” The tool supports baseline modeling, post-retrofit model conversion, savings calculation, continuous monitoring, real-time alerts, and automated reporting. Its methodology is aligned with IPMVP and provides CV(RMSE), NMBE, and uncertainty intervals based on conformal prediction.

Data, Platform, and Integrations

The product workflow covers building registration, zone and system definition, event definition, data upload, model training, baseline calculation, post-retrofit updates, and savings quantification. Its hierarchical structure supports analysis by building, thermal zone, and HVAC system, and can aggregate savings results at the building portfolio level. The text notes that data can be shared without reformatting or renaming features, but it does not specify support for APIs, BMS/IoT platforms, data warehouses, or third-party system integrations.

Pricing and Support

The content explicitly states that the Meval tool is available for free access, and offers demo scheduling, white paper downloads, and a contact form. The contact information shows an office in Athens, Greece, with business hours from Monday to Friday, 9:00–18:00 EEST, and promises a response within 24 hours after submitting the form. Pricing for commercial editions, enterprise contracts, SLAs, training, and the long-term free-access policy are not disclosed.

Pros, Cons, and Who It’s For

Its strengths are its professional methodology, especially for attributing HVAC retrofit savings, IPMVP-aligned verification, handling non-routine events, and monitoring energy savings across building portfolios. Its drawbacks are that the product is highly vertical and may have a steep learning curve; it has almost no direct use for marketing or SEO teams; and information on integrations, permissions, data scale, and commercial support is limited. It is best suited for energy engineers, energy service companies, building asset managers, and project teams that require rigorous M&V.

Access from China

The content does not provide information on access speed from mainland China, ICP filing, a Chinese-language interface, RMB payments, or local support, so its access status should be considered unknown. For teams in China, it is recommended to first verify whether the web tool can be accessed reliably, assess data cross-border compliance requirements, and check through a demo conversation whether enterprise deployment or alternative access options are available.
