description
As coberturas e fachadas mediterrânicas, vivas e produtivas promovem o bem estar e a qualidade de vida das populações e contribuem decisivamente para o aumento da resiliência das cidades. Por esta razão é essencial não apenas o conhecimento das soluções existentes que melhor se adaptam ao nosso clima, como ainda o desenvolvimento das competências técnicas essenciais para a boa implementação daquelas soluções. O enfoque deste Workshop está na demonstração da integração da dimensão verde nas cidades e das oportunidades de intervenção conducentes à melhoria do desempenho energético dos edifícios, à redução do “efeito ilha de calor”, à boa gestão das águas pluviais, à reciclagem de águas cinzentas, à melhoria da qualidade do ar, ao aumento da biodiversidade e à segurança alimentar das populações urbanas, sempre assentando nas melhores e mais adequadas tecnologias disponíveis. Green roofs and façades are becoming increasingly recognised for their contribution to urban wellbeing. This contribution is becoming increasingly measurable, and is providing considerable economical and environmental benefits to individuals, communities and the urban environment. Cities all over the world are increasing their quota of green spaces and surfaces, finding it improves many of the urban performance indicators they have failed on in the recent past: their air quality ratings and their storm water management improve, their heat island effect decreases, social integration improves and health is more effectively restored... The Workshop provides an opportunity to share good practices in the built environment and aims to provide sufficient evidence for decision makers to gain courage and go for solutions that integrate this green, living dimension. The Workshop’s target audience are all decision makers who influence the quality of the built environment. O Workshop é dirigido a todos os decisores que influenciam a qualidade de construção do meio edificado

Transforming the build environment

VYDROVYDRO®® substrate, a unique materialsubstrate, a unique material
A unique hydrophilic material that
is transforming the construction of
green roofs, vertical walls and soft
urban landscapes.
Due to the physical, internal
structure of VYDRO® substrate,
water molecules can easily enter
its cells but cannot easily exit it.
This means that water is stored in
the VYDRO® matrix, where it can
be readily accessed by plant roots.
Properties & Benefits
Properties of VYDRO®
Up to 70% lighter than existing green roof systems (30 kg/m!) Can take up to 30 times its weight in water (900 l/m!) Water buffering capacity of 40 – 60% Water draining: 65% still left after 24 hrs
Benefits Easy to handle / install Very suitable for old buildings and/or industrial building with
structural weaker roofs (load < 100 kg/m2) Cost efficient to transport (on average 4 time more m2 vs. standard
substrates) Ability to rehydrate over multiple cycles – it does not dry out Improved building insulation, reducing cooling costs Reduced time and total installation costs Increased roof life

Determination of water retention of VYDRO® substrate
PU-Europe study : LCA of green roofs
Comparative life cycle assessment (LCA) of a green roof system with VYDRO® substrate versus two conventional green roof systems
Third party : VITO – Flemish Institute for Technological Research
Potential environmental impacts
Transportation
3 types of green roofs :
1. using a retention layer with VYDRO substrate
2. with lava substrate
3. with demolition material from construction
Climate zones
Temperature - water retention capacity of 30l/m3
Mediterranean - water retention capacity of 60l/m3
LCA Outcome
7 Environmental impacts
LCA Outcome
Conclusion :
1. The VYDRO® green roof system scores better in most of all seven environmental impact categories than the green roof with basalt layer and the green roof with substrate from demolition material.
2. Transportation is equally important, less CO2 emissions and less fuel consumption because of VYDRO® substrate being very lightweight.
Transportation to construction site : 16700 kg/500m2 VYDRO® green roof 170000 kg/500m2 demolition material green roof 127960 kg/500m2 basalt green roof
Overview of transportation of components of the green roof systems
With basalt substrate – 127960 kg/500m2
With VYDRO® substrate – 16000 kg/500m2
With demolition material – 170100 kg/500m2
Green roofs
Green roof of public housing project
Project: Ex-military hospital – Green QuarterLocation (City, Country): Antwerp, BelgiumConstruction year: November 2011Roof size: 1200 square meters (sqm)Building type: Private propertyVegetation: sedum matsGreen roof installer: IBIC, Belgium

VYDRO® substrate has been used to create a sedum green roof of 1200sqm on top of an ex-military hospital in Antwerp, Belgium. The roof structure needed a lightweight solution and VYDRO® substrate had all the right credentials to meet requirements.
This innovative smart water management system enables the creation of green roofs in locations where weight and structural strength are a critical factor. VYDRO® substrate weighs up to 70% less than other green roofing substrate systems (1m3 = 30kg only).
Why VYDRO® substrate ?
Enables the creation of green roofs in locations where weight and structural strength are a critical factor.
VYDRO® substrate weighs up to 70% less than other green roofing substrate systems (1m3 = 30kg only).
Particularly well suited to retrofit green roofs, thus overcoming a key problem in many historic urban areas.
Transforming ordinary roofs into green roofs with VYDRO® substrate offers multiple benefits:
• Improved insulation and reduce energy consumption
• Improved air quality with additional plants that filter out pollutants
• Foliage helps dampen sound, reducing noise pollution
• Reduced rain water run-off so lowering the risk of localized flooding
• The heat-absorption effect associated with exposed hard surfaces is mitigated
• Biodiversity is encouraged.
Green roof of Florence hospital
Project: Florence HospitalLocation (City, Country): Florence, ItalyConstruction year: September 2011Roof size: 1500 square meters (sqm)Building type: Private propertyVegetation: Grass and various plantsGreen roof installer: Poliflor, Italy
VYDRO® substrate has been used to create a sloped green roof of 1500sqm on top of a hospital in Florence, Italy. The roof has a south facing aspect and therefore needed a solution with high water retention capabilities.
Using VYDRO® substrate means the grass needs to be watered less – resulting in 60% less irrigation costs.

Vertical Walls
Vertical wall of Salcheto winery cellar
Project: Salcheto wineryLocation (City, Country): Montepulciano-Tuscany, ItalyConstruction year: January 2012Vertical wall size: 100 square meters (sqm)Building type: Private propertyVegetation: FLEXIVERDE® systemVertical wall installer: Poliflor, Italy
Copyright Salcheto
VYDRO® substrate has been used to create a vertical wall on the exterior of a wine cellar at the Salcheto vineyard near Montepulciano (Siena) Tuscany.
The main objectives of the project were to mitigate the impact of the concrete structure in the beautiful Tuscan landscape and to insulate the cellar to reduce energy consumption.
The installation uses FLEXIVERDE® - a system from Poliflor - which contains VYDRO® substrate. Easy to install the solution was pre-cut prior to application to achieve a specific visual planting pattern.
Why VYDRO® substrate ?
Ideally suited to the creation of vertical gardens and living walls.
Lightweight, the substrate weighs up to 70% less than other plant substrate systems (1m3 = 30kg).
Offers a water retention capacity of 30 liters/sq with a total weight lower than 45kg/sqm when fully saturated.
Roots can easily penetrate the inert, PH-neutral open structured substrate enabling rapid growth of plants.
Transforming ordinary walls into living walls with VYDRO® substrate offers multiple benefits:
• Improved insulation and reduce energy consumption
• Improved air quality with additional plants that filter out pollutants
• Foliage helps dampen sound, reducing noise pollution
• Reduced rain water run-off so lowering the risk of localized flooding
• The heat-absorption effect associated with exposed hard surfaces is mitigated
• Biodiversity is encouraged.
