Passivhaus Certification

THE FEEL OF OUR BUILDINGS

<< Now it is possible to build flagship homes, with the greatest energy efficiency, reducing construction time, raising profits while providing higher quality and comfort. >>

SPECIALISTS IN PASSIVHAUS CERTIFICATION

  • All Lobe Group buildings are committed to obtaining the Passivhaus Certificate, the most demanding and recognised worldwide in terms of energy efficiency, which offers thorough quality control, both in the design stage and in its correct implementation.
  • Currently, VAND Arquitectura and ENERGIEHAUS are entrusted with the certification of Lobe Group’s buildings. They are approved by the German Passivhaus Institute. This accredits them to certify that all calculations, measurements and requirements of the standard are met.

GREATER COMFORT PLUS REDUCED ENERGY CONSUMPTION

The Lobe Group has given an overhaul to the construction industry through its state-of-the-art working method for off-site pre-cast façades assembled in our own manufacturing facility, COMBO BUILDING SYSTEMS S.L.

This system combines finishings, insulation and watertight sealant in a single unit, thereby overcoming efficiency issues arising in thermal bridges in the façade, floor slab faces and pillars. Furthermore, installation is performed as a single piece that includes the pre-frame, sealing, window and glazing, which entails a considerable saving both in terms of time and costs.

The industrialised production of the façades ensures a wholly accurate installation process, while reducing debris in the form of waste materials and improving the buildings’ thermal properties, thereby providing greater comfort and energy efficiency. The Lobe Group stands proudly at the forefront of sustainable and efficient construction processes.

The standardisation of elements of the thermal envelope allow for all the buildings’ to be implemented using the same construction system: pre-cast and self-supporting modular panels that arrive on site with a tailor-made design and need only be assembled.

The panels are composed of several layers and are designed to be able to determine in a single element the building’s thermal and hermetic envelope, so that the work on the project is limited to suitable treatment of the joints and intersections.

Once the assembly of envelope panels and sealing of joints has been completed, carpentry elements are placed to be able to check the building’s airtightness while the sealing layer is visible. In this way, possible errors can be detected and corrected to ensure proper airtightness. Any space is sealed in hollows or slits to avoid insofar as is possible the infiltration of unwanted air and preserve property's comfort levels.

At Lobe Group, we carry out at least two Blower Door airtightness tests to check these infiltrations in each house before considering the façades’ construction and continuing with the coming project stages.

This consists of a ventilation system fitted on the roof and which combines with a local fancoil in each property. In this way, the dual installation of air conditioning and ventilation ducts is avoided. The same system is used to heat, cool and ventilate the properties.

To fulfil each proprietor’s needs, a mechanical damper has been installed that adapts the air flow depending on the CO2 concentration inside the property. The ventilation machine thus responds to the damper’s action through constant pressure technology. The actual fancoil is entrusted with the task of providing the necessary energy to either cool or heat the property as needed. The fancoil’s recirculation allows for the metering of the power supplied.
