In developing the Mobile Energy-Saving House "MESH", BASF, one of the world's leading chemical company has created a real showpiece property, which combines the concepts of saving energy and protecting the environment.
MESH is a mobile miniature passive house launched in early 2009 by BASF and five German partners: r-m-p architects, window and door manufacturer Ludwig Häußler, building systems provider Nilan Deutschland, stay-in-place formwork and floor panel manufacturer Lohr Element, and wood element manufacturer inholz.
A passive house can make do without conventional heating or air conditioning, yet it stays cool in summer and warm in winter. Passive houses are not only energy-saving houses but have a palpably better indoor climate than conventional buildings. A current EU Directive stipulates the standard of ‘nearly zero energy buildings' to become the future energy standard for all new buildings. The building style typically includes a seamlessly insulated shell and a refined ventilating and heat recovery system.
The energy demand is low: A passive house, as defined by the Passivhausinstitut Darmstadt, Germany has a residual heat demand of 15 kWh per square meter per year for heating, which corresponds to a fuel value of 1.5 liters of heating oil. The total amount of primary energy used for any extra heat, hot water and electricity must not exceed 120 kWh per square meter per year.
