e4plus AG

What e4plus AG does

e4plus AG is a Swiss energy consulting firm founded circa 1989–1990 and headquartered in Kriens, Luzern. The firm operates from Haus 2050, the first MINERGIE-A-ECO certified building in Central Switzerland, which doubles as a demonstration project. e4plus serves Swiss municipalities, cantonal and federal authorities, associations, and private property owners through three integrated service areas: Bildung und Information (education and information, including event coordination and training); Raum und Daten (spatial energy planning, energy data management, and regional development); and Gebäude und Energie (building energy consulting, GEAK certification, sustainable construction, and solar energy planning). The firm is an accredited Energiestadt advisor for approximately 20 municipalities and holds direct federal mandates for the Fachstelle Energie-Region (2014–2020) and the Koordinationsstelle Solarbildung Schweiz (since 2016) on behalf of the Swiss Federal Office of Energy.

The company's core technology is the Geoportal, an interactive web-based geographic platform that presents spatial energy planning outputs including energy maps, Energiestadt municipalities, solar potential calculations, and excursion tips. The Geoportal is positioned as a digital collaboration tool with customers rather than a standalone commercial product. The firm maintains a project portfolio across Central Switzerland covering municipal energy strategies, heat network feasibility, PV planning, climate adaptation, and Impulsberatung erneuerbar heizen (subsidized impulse consulting for renewable heating transitions).

e4plus AG is a privately held Swiss Aktiengesellschaft with no external institutional investors, no funding rounds, and no public listing. The company is owned by its partners: founder Markus Portmann (Chairman of the Board), Priska Lorenz (Co-CEO), and Moritz Kulawik (Co-CEO). The firm employs 11 people and operates a sales-led, project-based B2G consulting model with multi-year program contracts (e.g., federal mandates) and per-engagement project mandates. Revenue is generated through professional services fees and program coordination contracts, with no publicly disclosed pricing or subscription tiers. Distribution is entirely direct via consulting engagements, supplemented by the Energie Apéro Luzern event series and webinar-based homeowner outreach.
