Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
While the Living Lab concept is applied at international level in many sectors, their role in facilitating innovation in the water sector needs more practical exercise especially at small scale tackling water challenges at the “grass roots”. The current initiative aims to provide evidence and guidance to support water related living labs initiatives making a step forward from TRL 7 towards TRL 9.

How does it work?

The Potelu Living Lab is focused on the idea to put the local community in the driver seat for increased capacity to transform local challenges into opportunities. Specifically this involves to partner between different stakeholders for developing local capacity to identify and manage solutions to mitigate climate extreme events and increase resilience of population, environment and economic activities and at the same time to design and implement those solutions that also directly impact on local development and restore the attractiveness of the region for different population categories. The combination of water related risk mitigation actions which also build on economic opportunities will be at the core of the Potelu Living Lab approach.

The Polder Roof transforms a flat roof so that it is able to collect and store water. This storage is controlled and can be drained at any chosen moment. The Polder Roof functions as a foundation for a green roof, roof garden, solar park or roof park.
ProSystem prototype demonstration in operational environment.
Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
The Polder Roof has already been implemented on several pilot roofs in the Netherlands. We want to test en optimize the algorithms that decide to retain the stored water or not. We intend to enhance these algorithms, add (probabilistic) forecasts and models and test them on a Field Lab at the Civil Engineering faculty of Delft University.

How does it work?

The Polder Roof consist of a buffer system and a Smart Flow Control. Rainfall is directly stored in a buffer system on a flat roof. The standard capacitiy of this buffer system is 70 mm. This storage is automatically controlled by our Smart Flow Control (SFC) which collects meteorological data and communicates with a web-application. The Smart Flow Control uses algorithms to decide to retain the stored water or not.

Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
There are already two operational flood forecasting systems running daily in Taiwan and in Australia. DAM software (including D-GeoStability) has been proven in competative manufacturing and is a well developed and known software.

How does it work?

The end-user gets its personal viewer/dashboard in the cloud (secured by password) and is able to send warning messages if flood risk becomes too high. In this dashboard/viewer the end-user can see every new update, can look back at historical results and can take a look in the future (2hrs ahead). Besides, the professional user can see the background information, like the water levels, the precipitation, the actual strength of the levees.

ARIEL, soil moisture retrieval by microwave remote sensing

ARIEL is a microwave radiometer that provides remote soil moisture data. What cameras cannot see beyond surface, Balamis sensors can. ARIEL is a non-intrusive method able to effectively retrieve soil moisture data over small and large areas easily. ARIEL can be placed on-board aircrafts, UAVs (Unmmanned Aerial Vehicles) and ground vehicles.
ProSystem prototype demonstration in operational environment.
Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
Technology has been tested and demostrated in an operational environment, and has passed the BRIGAID's TIF assessment.

How does it work?

ARIEL is a passive microwave radiometer based on the same technology of MIRAS sensor on-board satellite SMOS mission. It measures natural thermal emission at the microwave wavelength of 1.4 GHz, which is strongly related to the content of water in the observed target. It requires a power supply from 12 to 24V, and consumes a max. of 50W. It requires a mechanical interface with the platform to be used on. Its installation takes less than 10 min. in ground vehicles and UAVs, and needs to be homologated in aircrafts. The antenna has to be adapted to existing “holes” for Earth observation in the fuselage, and data is synchronized with other systems using an internal GPS time stamp.

Seed blanket for Extensive Green Roofs

To lower threshold for consumers and to accelerate the transition to more green roofs in historic urban areas, we offer a lightweight, easy-to-install green roof system that is cheaper than current extensive green roof build-ups, by 1) using cost effective build-up materials and 2) saving money on transportation and installation cost (even suitable for DIY).
ProSystem prototype demonstration in operational environment.
Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
The build-up system has been defined. A successful test set-up in western Europe, ideal conditions (mild temperature and humidity) installed. More testing required in other regions (e.g. south and continental Europe) to validate it can be successful across Europe.

How does it work?

The product is an extensive green roof system which consists of a Drainage layer; Growing medium; Composite Seed blanket and Ballast. Apart from the ballast, all layers of the system are sheets or blankets rolls. All materials are dry, and can be stored for a long period. The seed blanket is an unvegetated composite, which contains a sedum seed mixture that can be customized to withstand different climatological conditions. This allows potential use across Europe. By using geotextile as growing medium, additional substrate is not required. With a weight of ±53kg/m² the system is very lightweight compared to standard extensive green roofs(>100kg/m²). Current system retains 25L/m², which can easily be increased using alternative geotextiles.

Rooftops are generally poorly used areas and therefore have enormous potential. The Polder roof uses the roof surface to create a water buffer and create a new roof surface for other rooftop functions. The Polder roof then controls the flow of rainwater to the downspout. When it is raining the rainwater runoff is stopped and when the rainwater in the sewage system is processed the Polder roof starts to empty the rainwater buffer, offsetting the peak of rainwater flow into the sewage system.

Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
We have made one polder roof last year and are planning to build four more in the next month, however there are still some problems to be tackled in production level and on the IT side of the product.

How does it work?

The Polder roof consists of a water buffer created from modules that create a void where rainwater can be stored in. This buffer is locked in by the edge of the roof or dikes creating a basin. The third element is the “Smart Flow Control” which is a control unit that controls the water level height in the water buffer and ensures the safety aspects of the roof with input of several sensors that measure environmental effects on the rooftop.

PrHo is a software for the estimation of greenhouse-grown crop water requirements and actual evapotranspiration based on the FAO model
ProSystem prototype demonstration in operational environment.
Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
The software has been tested and validated in greenhouses experiments for the most typical crop growing cycles in the Almeria province (SE Spain).

How does it work?

PrHo quantifies crop water requirements based on two sub-models: a) a reference evapotranspiration (ETo) sub-model, and b) a crop coefficients (Kc) sub-model. The ETo sub-model computes greenhouse ETo values using outside solar radiation estimates retrieved from a radiation model previously calibrated for local conditions. Outputs from this sub-model make possible to adjust the irrigation scheme to particular crop conditions, such as white washing. The Kc sub-model computes the temporal dynamics of Kc values along the growing period, from the sowing/planting to the effective full cover stages. as a function of thermal time retrieved from greenhouse air temperature measurements.
