Jury evaluation
"With their sophisticated skylight design, these compactly laid out, 1,000-m² kindergarten facilities interact in a carefully designed manner with the outdoor area and create a lively indoor space with a large building depth on this site which is approximately square-shaped. Lighting with natural daylight is also supported by a facade with a light-diverting function. Working from the basis of the passive-house standard, the goal of a zero-energy house, to include all consumption areas, is to be achieved using a solar power system integrated into the roof. A heat pump with borehole heat exchangers which serves as a heat source/sink is used for heating and cooling."

Building concept
A crèche for around 60 children in five groups is to be built on a part of Bayer CropScience AG’s Monheim site which is accessible from the public street.
Based on the passive-house energy standard targeted at the survey stage, the goal of a CO2-neutral building was developed and defined during the course of planning work. This is to be the first crèche in Germany with an operational energy balance that is neutral over the whole year and thus also climate-neutral.
The building design is based on a highly insulated post and beam construction method, which is in line with the ambitious energy goals of the project. By preassembling the wood components, a high level of craftsmanship combined with a short construction time will be achieved.
Energy concept
A number of measures are planned to achieve a zero-emissions balance:
All occupied rooms are to be equipped with highly-efficient, daylight-dependent lighting. Skylights combined with sun-protection features will allow for the targeted use of daylight. A mechanical ventilation system with highly efficient heat recovery and favourable fan efficiencies, combined with a heat pump to exploit the geothermal potential of the site and the support of a solar thermal system, will provide an efficient heating, ventilation and hot water system.
The entire electricity requirement is to be supplied by a grid-connected photovoltaic system located on the roof. With these measures, a neutral energy and emissions balance over the whole year is to be achieved.
