What KALORIMETA AG & Co. KG does

KALORIMETA AG & Co. KG, operating under the brand KALO, is a Hamburg-based service provider for the German residential housing market, organized within the noventic group. Founded in 1985, the company delivers legally compliant heating cost billing (Heizkostenabrechnung), operating cost billing (Betriebskostenabrechnung), energy performance certificates, smoke detector services, electronic invoicing, and CO2 cost allocation calculations for both private landlords and institutional housing companies (Wohnungswirtschaft). Its products and services are anchored in German regulatory frameworks including the Heizkostenverordnung, the CO2-Kostenaufteilungsgesetz, the Mess- und Eichverordnung, and EU Regulation 2023/2854 (EU Data Act), positioning KALO as a compliance-critical vendor for property portfolios across Germany.

Operationally, KALO distributes its portfolio through more than 50 physical service locations nationwide combined with digital self-service channels — a landlord-facing Kundenportal, the resident-facing Bewohnerportal, the KALO Home consumer app, and the KALO Smart thermostat companion app. The technical foundation consists of German-manufactured radio-based metering devices (Funk-Heizkostenverteiler, Funk-Wärmezähler, Funk-Wasserz\u00e4hler) communicating via mobile network gateways to a Hamburg-based data center, plus a smart thermostat system developed within the noventic group using tado° technology. The smart thermostat product, validated by the Karlsruhe Institute for Technology at 15.5% average heating energy savings and TÜV Rheinland-certified under DIN 94679-4 for adaptive hydraulic balancing, is purpose-built for multi-party residential buildings and is partially subsidizable under the BAFA BEG EM program.

The revenue model combines recurring subscription-style service fees (heating/operating cost billing, smoke detector inspection, UVI subscriptions), hardware sales or rental of metering devices, and one-off professional services such as energy performance certificates. Pricing is quote-based and tied to property size and postal code, with a discounted property fee (reduzierte Liegenschaftsgebühr) for customers submitting data digitally — a behavioral lever designed to drive PLG-style adoption inside an enterprise field-sales motion. The company is privately held as a GmbH under the noventic group; Dr. Dirk Then is the CEO.

Core offering

KALO provides consumption-based heating cost billing and operating cost billing services for German residential properties, supported by proprietary radio-readable metering technology (heat cost allocators, heat meters, water meters) manufactured in Germany. The company complements its billing services with smart thermostat solutions for multi-party residential buildings, adaptive hydraulic balancing, smoke detector services, energy performance certificates, and digital platforms (customer portal and resident apps) that deliver legally compliant sub-annual consumption information (UVI) to tenants. Together, these offerings address German regulatory mandates including the Heating Cost Ordinance (Heizkostenverordnung), the CO2 Cost Allocation Act (CO2KostAufG), and the remote-readable metering requirement effective end of 2026.

Product overview

KALO is a subsidiary of noventic group offering a comprehensive portfolio of energy management services and IoT-enabled metering solutions for the German residential housing market. The portfolio is organized into four pillars: (1) Core billing services — Heizkostenabrechnung (consumption-based heating cost billing), Betriebskostenabrechnung (operating cost billing), supported by radio-readable measurement devices (Heizkostenverteiler, Wärmezähler, Wasserzähler) manufactured in Germany; (2) Smart heating solutions — Smarte Thermostatsteuerung (smart thermostat system for multi-party buildings with PID regulation, window-open detection, and app-based control) combined with Adaptiver Hydraulischer Abgleich (adaptive hydraulic balancing, TÜV Rheinland certified per DIN 94679-4), enabling energy savings of ~15.5% per KIT study; (3) Immovable services — Energieausweis (energy performance certificates), Rauchwarnmelder-Service (smoke detector management with remote inspection), UVI (mandatory monthly consumption information), E-Mobilität (e-mobility charging), and Smart Metering; and (4) Digital platforms — the Kundenportal (web portal for landlords/property managers) and Bewohnerportal/KALO Home app (resident-facing mobile and web app for energy consumption monitoring). Related digital tools include the KALO CO₂-Kostenrechner (online CO₂ cost calculator) and KALO-Servicecenter (online help center). The EU Data Act (Art. 3 Abs. 2) obligates KALO to provide users access to thermostat-generated data in CSV format on request.
