Geothermal energy · geocooling · radiant ceilings
A local, silent energy source that heats in winter and cools in summer, managed by a single point of contact.
A higher energy class and measured consumption after the works.
Façades, roofs and details designed to enhance the building, not just insulate it.
A single lead, open prices and steady comfort all year round.
A full renovation for apartment buildings, premium energy solutions for houses. Each project is designed for its building.
D1 · Property management companies, condominium owners, cooperatives, municipalities, investors
Transform a building constructed between 1950 and 2000 within a single vision, rather than adding up isolated interventions.
D2 · Houses and private owners
A complete energy architecture, designed around the house, your goals and the permits available.
According to the Federal Statistical Office (FSO), most homes built before 2001 are still heated with oil. Geothermal energy and radiant ceilings change this.
Orders of magnitude, with no guarantee for any individual building: the result depends on the system and the building.
Façades, roof, windows and solar shading reduce and stabilise demand.
Geothermal probes where the address is eligible, or a renewable alternative.
Water-to-water heat pump, domestic hot water and low-temperature hydraulics.
ONIVO ceilings, geocooling and dew point control.
Photovoltaics, battery storage and vehicle charging.
Zenheat Care monitoring, then energy management.
The owner keeps the decision. Zenheat ensures consistency, from the first visit to the monitoring of consumption.
Condition of the building, usage, running costs and expectations.
Costed options, subsidies and phasing.
An overall strategy before separate work packages.
Cantonal procedures, grants and drilling.
Competing contractors working from a common specification.
Planned works, limited disruption.
Adjustments and monitoring after commissioning.
Fees disclosed before the mandate
Contractors’ bids are compared on a common basis. The selected packages are presented to you at their award price, and you keep the decision.
Design, tendering, coordination, site supervision and commissioning are covered by separate fees.
For a full mission, based on the reference budget of the managed works, depending on the scope and complexity of the project.
The rate, the amount and the services included are set out in the mandate offer, after the diagnosis and before signing.
Any significant change of scope is submitted to you before fees are adjusted.
Package awarded at the tender price, with no added margin. Differences in price and scope are explained to the client.
The CECB (Swiss building energy certificate) measures the efficiency of the envelope and of the building. A full renovation aims for several classes of improvement, to be confirmed by the energy study.
Illustrative example. The class that can be achieved depends on the condition of the building, the scope of works and the energy study.
Conceptual visuals These images show the potential of typical buildings, not completed projects. Zenheat projects will present their measured data: consumption before and after, CECB, summer comfort, budget, subsidies, works duration and number of apartments.

Investor pathway
Zenheat partners with investors to acquire and renovate buildings constructed between 1950 and 2000, with a sound structure and demonstrable potential.
The financial partner provides the capital for the purchase and the works, under a structure specific to each project.
Zenheat manages permits, studies, tenders and the construction site, with the aim of reaching energy class B or A.
The renovated property is resold on the basis of its performance and comfort. The net profit is shared between the project partners.
Shared net profit
Sale price − acquisition − works − financing − company costs − other project costs

First step · free of charge and without obligation
Enter the building address and your contact details. Zenheat checks drilling feasibility and available grants, then contacts you with initial guidance.
Feasibility depends on the address, the canton, water protection rules and the project. The grant application must be submitted before work begins.
