Certifications

For many years, Thomas & Piron has made available to its clients a growing expertise in the field of construction techniques and the design of passive building projects in the Grand Duchy of Luxembourg.

We have thus acquired a number of certifications attesting to the quality of our completed projects:

Thomas&Piron is a certified “Passivhaus Handwerker”

The “PassivHaus Handwerker” certificate (passive house craftsman)

This certification has been developed by the renowned “Passivhaus Institut” with a view to providing training in all passive building techniques and concepts. The list of certified companies is also provided on the institute’s web site.

The establishment of a certificate of this type by the “Passivhaus Institut” was prompted by the European directive 2010/31/EU on the energy performance of buildings. This directive requires that all new buildings should be close to “zero energy” by 2020. In Luxembourg, all new residential buildings must attain the “passive” standard (class AAA) at the latest by 2017.

The PassivHaus Institut
Located in Darmstadt, in Germany, this independent institute was founded in 1990 following the design of an initial demonstration passive house which achieved record low energy consumption.

Since then, the “Passivhaus Institut” has held the position of a European leader in the research and development of concepts for the constructions of passive houses, offices, apartments and professional buildings. In addition, this institution is at the origin of the passive certification of various components in modern constructions (doors, windows, insulation and ventilation systems, etc…).

The “Passivhaus Institut” has also perfected benchmark algorithms and software packages used as a basis for new energy legislation in every European country, including the well-known Certificat de Performance Energétique (CPE) [Energy Performance Certificate] in the Grand Duchy of Luxembourg.

Thomas&Piron’s investment and responsability concerning this Certificate
With its experience in the construction sector, and more particularly in the construction of passive houses, passive apartments and passive professional buildings, Thomas et Piron is committed to the enhancement and evolution of its construction techniques.

Mr Pasquasy Francis, a benchmark technical manager in passive constructions in the Grand Duchy, having followed recent specific training from the “Passivhaus Institut”, is involved in the design of all passive and low energy projects, in collaboration with the design offices.

Thomas&Piron is also committed to a vertical integration policy and provides training for all site workers and technical staff through the use of a competencies and training centre that is unique in Europe. A technically equipped training and presentation hall in Strassen also enables all clients to be provided with clear, practical information.

Thomas&Piron has the “Energie fir d’Zukunft+” certification

The “Energie fir d’Zukunft+” certification
This certification was created by the chambre des Métiers [trades chamber] of the Grand Duchy of Luxembourg in 2012. This certification enables clients and future constructors to identify the construction companies that have acquired specific competencies in the field of very high energy performance house and drainage system construction.

The establishment of a certification of this type by the authorities in the country has been stimulated by the European directive 2010/31/UE on buildings’ energy performance. This directive requires all new buildings to be close to “zero energy” by 2020. In Luxembourg, all new residential buildings are required to meet the “passive” standard (class AAA) at the latest by 2017.

Thomas&Piron, with the TomWood concept, has the “Sustainable Construction” accreditation
Sustainable Concept
Designed, adapted, and perfected over many years, and with the accrued experience of its 180 houses already built, the TomWood construction concept is rooted in the principle of respect for the criteria of sustainability.
As from 1 January 2017, all new building permit applications can benefit from new State support with PRIMe House 2017.
Besides the renewal of support for the installation of solar panels, wood pellet boilers or geothermal heating, it is the recognition for the creation of sustainable housing which is now attracting the interest of prospective builders. For a 150 m2 house, this means €24,000 paid to the purchaser if the sustainability criteria specified in the new regulation have been met.
In brief, the determining criteria for the sustainable characteristics of a residential property are:
• The ecological criterion, including the environmental assessment of construction materials.
• The quality of the building and of its technical installations (dismantling capacity, performance, acoustics, thermography analysis, airtightness, waste management, etc…)
• The functionality of the construction (accessibility, ventilation, parking, etc…)

A the request of its future owners, this can be implemented using the calculation method derived from the Lenoz certificate, which the TomWood partner engineering offices will complete and adhere to the list of minimum criteria imposed by PRIMe House 2017.
