One-stop-shop concept

What is a ‘One-Stop Shop’

A one-stop shop is a company / consortium, that offers a multitude of products or services to its customers. One-stop-shop can refer to a specific location, meaning that all the requirements a client has can be carried out at that location. For example, a bank may be able to offer you not only personal banking services and loans, but also investment advice, investment vehicles and insurance policies. Compared to visiting a separate institution for each area of need, the one-stop shop saves the consumer a lot of time and effort.

The one-stop-shop concept is a concept for the end-user, but also for the production.  In this ‘one-stop-shop’ proposition the end-user will deal with only one party, responsible for the total renovation, starting from an inventory of the existing situation, inventory of specific end-user demands, translation into modular renovation kits, mounting and installing, financing and aftercare.

Models for a one-stop-shop concept (EU)


The individual interest of ordinary residents/end-users is mostly not focused on energy saving, but there are plenty desires for improving the houses, such as improving the indoor air quality, thermal comfort, to improve the acoustic quality, protection for burglary, etc. Many of these improvements are efficiently to combine and to integrate with energy saving measures. A web-tool will be developed to inventory the needs and wishes of the inhabitants. This will be translated to a Statement of Requirements  (SoR) as extra input for designing and production of nZEB concepts. A standardised list of options will be developed, that can be integrated with the production of the elements without compromising the main function.

The high level of prefabrication and the use of smart connectors (mechanical, hydraulic, air, thermal, electrical, ICT) will limit the actual renovation time on site to a maximum of 5 days with a goal for an average of two days, including the complete or partial removal of the existing facades and roofs or other elements. During the renovation the occupants can stay in their homes and have a minimum disturbance. 

A specific feature of these smart connectors is the development of Plug and Play connections of modular components. These Plug & Play connectors make it possible to reduce the renovation time.  Smart combinations of components and executions ensure extra performances for nZEB concepts, healthy indoor climate, safety and accessibility. The various components communicate by integrated (wireless) sensors and control components for performance diagnostics and control.

A system of performance guarantee (EU

Three main modular elements are discriminated:

Modular facade elements, combining all facade functions like:

-Thermal insulation, acoustical insulation, moisture safety, water and air tightness

-Daylight and solar shading

-Ventilation with heat recovery

-Heating and cooling emission

-Fire safety

-Burglary protection

-Architectural quality and visual upgrading of the neighbourhood

-Extra features as heat storage (PCM’s)

-Renewable energy production on facades

Modular roof elements, including productive outfitting for renewable energy production, rainwater collection.

Modular ‘engines’, combining all necessary installations and building services in one prefab unit, with easy plug and play connections for installing.

These multifunctional elements will be produced and offered as tailor-made solutions for individuals as well as for housing companies, in mass production with the possibility of ‘n is 1 series’.

Finally, the end-users will get a guaranteed energy cost proposition for their renovated homes, based on their individual household profiles. An energy cost and performance guarantee is possible by the high level of quality control during the production process and the monitoring of performances of the most essential parameters related to energy use (ventilation, heating, indoor air temperature, micro climate conditions, electric appliances etc.) and remote diagnostics of the most important installations and building services.
