Overview

Kalomerita GmbH, which trades under the brand KALO, is a German service provider for the residential real-estate sector. Its stated role is to be a partner for the "smart energy transition in residential property" ("smarte Energiewende in der Wohnimmobilie"). The company combines consumption metering, heating and water cost billing, smart heating control and related building services, positioning itself as a one-stop contact for landlords, property managers and housing companies. KALO's core business is the automated, cross-sector recording of consumption, from submetering through to smart metering, in order to create consumption transparency as a basis for CO2 and cost savings. It supplies radio-readable metering technology — heat cost allocators, heat meters and water meters — and handles legally compliant heating-cost billing. The company also offers digital hydraulic balancing, smart thermostat control with an accompanying app for intelligent room-temperature management, smoke-alarm services and energy-performance-certificate creation. According to its own corporate communications, KALO draws on roughly 70 years of experience as a housing-industry service provider and serves private properties, small and medium-sized property managers and large public and private housing companies. It describes itself as an innovative pioneer in smart metering and multi-metering, and provides digital platforms and interfaces for efficient property management. It uses modern, digital and interoperable metering and control hardware "made in Germany" and maintains a Germany-wide network of service locations with local contacts. The company frames its work around a "Corporate Purpose": "A better climate begins at home" ("Ein besseres Klima beginnt zuhause"). It argues that the building sector accounts for roughly one third of German final energy consumption, and that making individual energy and water consumption visible helps residents optimize their behavior and contribute to resource conservation and climate protection. Its services are marketed under the tagline "Simple. Innovative. Personal." ("Einfach. Innovativ. Persönlich.").
