Construction of a new building and refurbishment work, Martha-Else-Haus, Hofheim, Germany

Cost

Technical building equipment & heating, ventilation and sanitary installations: approx. € 2.7 million (gross)

The demands

The Martha-Else-Haus is a retirement and nursing home that was opened in the German town of Hofheim am Taunus in 1963. The complex has grown over several construction phases and has its own kitchen. Before this construction measure, it offered placements for 47 residents and a day nursing care facility covering two entire floors.

The construction measures involved integrating further resident care rooms, twelve apartments suitable for the elderly and a medical practice. The project also required the optimization of internal processes and guaranteeing the parallel operation of inpatient care and day nursing care and catering for both forms of care from the in-house kitchen.

We achieved this by partially tearing down approximately 80% of the existing spatial profile in two stages and constructing a new building, also in two stages. At some stages during the construction phase, the home was fully occupied. The kitchen and day nursing care operations continued to run throughout the project. This was facilitated by installing and commissioning the new thermal heat energy generation system with a new gas connection alongside the old heating system, which was used to supply the existing building.

Our services

• Ventilation and air conditioning planning
• Planning a heating system with two condensing boilers and energy-saving areas with underfloor heating
• Planning central hot potable water generation with three fresh-water units and a solar heat system with a collector surface of more than 62 m² for care areas
• Planning local hot potable water generation systems for the apartments by means of mini fresh-water units integrated into the apartment units
• Planning air conditioning, including active cooling in the care area and in the assisted accommodation apartments to combat summer heatwaves

The result

We were able to plan the complex refurbishment and new construction work in two stages of construction in line with the deadlines while securing the required partial continued operation of the home during the construction phase at all times. The home can now make the most of needs-based utilities provided by modern, energy-efficient heat generation and drinking water systems. Residents and day nursing care guests can benefit from the integrated cooling system during heatwaves.
