Engineering practice for building services & energy technology

Building services engineering,
thought through from start to finish.

Building services design (HVAC, plumbing, electrical coordination) across every HOAI project phase, risk assessments and design review for developers, architects and building owners — from the first sketch to site supervision. Serving Germany, Austria, Switzerland and the whole Balkan region.

01 — Services

Five fields of expertise, one responsibility.

Every building is a system of energy, water and air flows — K5Ingenieure plans these systems as a whole, not as isolated trades.

01

Energy engineering within an integrated supply structure

02

Measurement and control infrastructure

03

Heating and cooling energy supply

04

Ventilation and air conditioning of buildings

05

Water, wastewater and gas supply and disposal

Also available: technical reports and risk assessments (including drinking-water hygiene per VDI 6023 / TrinkwV), design review of other firms' work on behalf of developers, infrastructure planning (supply and disposal networks beyond individual buildings), combined heat and power (CHP) plant design, and current work as an external site manager at a large power plant. Energy consulting including load-profile analysis and review of energy supply contracts — without issuing official energy performance certificates.
02 — About

From the trade to the drawing board.

Two perspectives on a building: the installer who builds it, and the engineer who designs it.

Before I designed systems, I installed them: my apprenticeship as a gas and water installer is where my career began — and it still shapes how I approach design today. Knowing how a riser is actually assembled changes how you plan it.

After completing my technical A-levels, I studied Building Services and Energy Engineering at TFH Berlin (today BHT), graduating in 2008. Years as a designer and project leader followed, most recently at a Berlin engineering firm leading my own planning teams, before I became fully self-employed in 2021 — under the name K5Ingenieure.
