Services
Renovation, conversion and new-build — for every building type.
We design HVAC and sanitary engineering for residential, commercial and industrial buildings. Our focus is on technical renewal, economical generation and low-operating-cost solutions — for clients, housing cooperatives and planning partners across German-speaking Switzerland.
Area of expertise
Building services renovation
Challenge
Existing buildings have different requirements than new-builds. We renovate heating, ventilation and sanitary installations in residential, commercial and industrial buildings so that they are technically up to date, economically sound and integrate into the existing building fabric. From condition assessment through variant studies to construction supervision, we accompany the project through all SIA phases.
Our expertise
- Condition assessment and evaluation of existing technical systems
- Renovation concepts with variant comparison and cost-benefit analysis
- Integration of heat pumps, district heating or renewable energy
- SIA-compliant construction planning and site supervision
Your result
An upgraded installation that fits the existing fabric, stays affordable in operation and can be delivered in stages.
Area of expertise
Heating system replacement
Challenge
A new heat generator is often the first step towards an energy-efficient renovation. We size the appropriate generation based on actual heat demand and assess which technology is ecologically and economically sound — from single-family homes to commercial properties. We consider funding options, connection conditions and long-term operation.
Our expertise
- Heat demand assessment and analysis of the existing heating system
- Heat pumps, district heating, wood or gas boilers including hybrid solutions
- Hydraulic balancing and adaptation of distribution systems
- Permit documentation and detailed engineering for the replacement
Your result
A correctly sized heat generator with a documented technology choice and funding-ready paperwork.
Area of expertise
Cooling
Challenge
For a good indoor climate, we design economical cooling solutions that suit the building and its use. Whether radiant cooling ceilings for even comfort, convective cooling beams, or flexible fan coil units for localised cooling — we compare systems by investment, operation, acoustics and integration into the building fabric, and jointly select the best solution.
Our expertise
- Radiant cooling ceilings for even, draught-free cooling
- Convective cooling beams and fan coil units for targeted output
- Comparison by investment, operating cost, acoustics and space requirements
- Integration with heating, ventilation and the building envelope
Your result
A cooling concept matched to use, acoustics and building fabric — backed by a transparent system comparison.
Area of expertise
Design for affordable housing
Challenge
Affordable living starts with the right technical design. We develop energy-efficient, low-maintenance and low-operating-cost HVAC and sanitary solutions for residential buildings, conversions and new-builds as well as for housing cooperatives and existing properties. Optimised and modular design approaches reduce investment costs from the outset and deliver low life-cycle costs alongside high living comfort.
Our expertise
- Low investment costs through optimised, modular design solutions
- Efficient heat and hot water generation for multi-family buildings
- Cost-effective ventilation and cooling concepts
- Economical sanitary and drainage solutions
- Focus on investment, operating and life-cycle costs
Your result
Low investment and operating costs with high living comfort across the entire life cycle.
Area of expertise
Preliminary cost estimate
Challenge
Already at this early project stage, we support clients with a well-founded preliminary cost estimate to assess economic feasibility and establish a realistic basis for fees. This helps to avoid fee miscalculations caused by construction costs set too high or too low from the outset. Our estimates draw on many years of experience from renovation, conversion and new-build projects — broken down in detail, communicated transparently and reliably substantiated.
Our expertise
- A sound basis for assessing economic feasibility
- A realistic basis for fees — protects against over- or under-charging
- Detailed breakdown by trade, cost group and item
- Transparent presentation without hidden contingencies or black-box calculations
- A reliable basis for budget planning, tendering and funding applications
Your result
A robust cost basis for budgeting, fees and tendering — transparently derived.
Technical foundations
The foundation behind our focus services.
Every project is built on solid HVAC and sanitary engineering competence. We master these trades and coordinate them from a single source — whether renovation, conversion or new-build.
Heating
Heat generation, distribution systems, underfloor heating and hydraulic balancing.
Ventilation
Comfort ventilation, indoor climate control, acoustic and fire protection.
Sanitary engineering
Potable water, hot water and wastewater systems.
Cooling
Cooling ceilings, cooling beams and fan coil units — designed for room use, acoustics and building fabric.
Trade coordination
Model-based coordination of trades and interface management.
Drainage
Foul and surface water, infiltration and retention — designed for local site conditions.
Funding programmes
Renovating with funding support — we provide the basis.
Funding is available for many renovations and heating system replacements. We prepare the technical documentation and support you through the application.
The Building Programme
National funding programme by the Confederation and cantons for thermal insulation, heating replacement and comprehensive renovations — coordinated with the cantonal energy authorities.
ProKilowatt & Klimastiftung
Contributions for efficiency measures in commerce and industry as well as for SME measures with a clear climate benefit — including the calculation basis for the application.
Cantonal programmes
Cantonal funding for heat pumps, district heating connections, solar thermal and other measures — varying by location and building component.
Note: we are currently preparing to offer GEAK reports in-house — until then, we work with accredited GEAK experts.
Renovation, conversion or new-build — we will review your project.
A short conversation often clarifies more than a long email. We will respond to your project enquiry within 72 hours.
