These are not used for temperature monitoring but for testing compressive strength. Sensor technology, by contrast, offers the opportunity to eliminate the need for these cubes and instead %u201clook inside%u201d the component in real time by measuring the temperature. The temperature, in turn, provides insights into the maturity of the concrete. This method is also covered by applicable standards. However, it is still mandatory to produce the %u201c28-day cubes%u201d required for conformity assessment. %u201cIn our experience,%u201d reports Lars L%u00f6wigt, %u201cthese sensors prove especially effective when working with innovative concretes. We use clinker-optimized and thus CO2-reduced cements, we have refined our concrete mix designs, and we sometimes pour concrete under less-thanideal weather conditions. Even in these circumstances, after calibrating the sensors in our lab beforehand, we achieve optimal results and can significantly shorten the formwork removal times and thereby the overall construction schedule.%u201dSustainable construction %u2013 KfW 55 and DGNB standardsMaison Westend is being built in accordance with current requirements for sustainable construction. Yasemin Flohr, architect and project manager at Lagrande Group for Maison Westend, explains: %u201cThe first three buildings are being constructed according to the KfW 55 standard for energy-efficient buildings, developed by the German development bank KfW. These buildings require only 55 percent of the energy consumed by a conventional new building, making them especially environmentally friendly.%u201d In this case, the project did not pursue certification from the German Sustainable Building Council (DGNB). %u201cAccording to our building physicists, with KfW 55 as our standard, we would have qualified for the DGNB Silver certification,%u201d Flohr says. The eight additional residential buildings planned for the later construction phases will meet the criteria for DGNB Gold certification.Project fact sheetProject: New construction of Maison Westend, Berlin-CharlottenburgClient / developer: Lagrande Group Projektmanagement GmbH, Berlin, in cooperation with Berlin housing association degewo AGArchitects: Tchoban Voss Architekten, BerlinGeneral contractor: Bauprojekt UKA GmbH, GiesenDemolition, concrete recycling & recycled aggregates: RWG I Gruppe, BerlinConcrete types: C30/37 XC4, XF1, evoBuild 70 (CO2-reduced concrete, CSC Level 1 certified), C30/37 XC4, XF1, evoBuild R30 (recycled concrete), C30/37 XC4, XF1, XA1 F3 D16, Heidelberg Materials Beton DE GmbHCements: CEM III/A 32.5 N LH (na) (evoBuild 50, CO2-reduced cement), CEM II/B-S 42.5 N, Heidelberg Materials, Plant K%u00f6nigs WusterhausenPrecast & semi-precast concrete elements: Heidelberg Materials Betonelemente DE GmbH & Co.
