To BGD or not to BGD, that is not the question now
BGD methodology meets the needs
of the future innovative spatial planning and design
of new cities and retrofitting of the existing ones.

The Blue Green Dream Principle
Synergistic merging of Green Infrastructure with
Urban Water (Blue) Systems

The Blue Green Dream Mission
Innovative urban planning through integration of urban water and
green infrastructure with other eco-system services to:
• Support urban adaptation to climate change  urban resilience
• Provide resource efficient, Blue Green Solutions
• Deliver, through use of Ecosystems Services, multiple benefits to
future new and retrofitted cities

Urban water systems development
Key BG principle:
Delivery of multi-benefit solutions through use of natural processes and
Maximisation of synergistic interactions with urban Ecosystem Services

Why BGD?
The threat of Climate Change…

Interactions of urban
ecosystem services

CP method = Possible analysis of interactions
Tensor decompositions are computed in parallel for sampled blocks, these are then merged
to obtain the global components A, B, C and a core tensor.

BGD Integrated Modelling System (IMS)
•BGD centred on interactions between:
 Different physical domains
 Physical and engineering systems
 Technologies and social systems
To capture these interactions, different BGD
tools and models tools need to communicate
and exchange data
BGD IMS interlinks BGD tools and models
Enables full benefits of BG Solutions and
Urban Ecosystems Interactions to be realised

Resulting benefits:
•Lower construction & operational costs
•Higher market value of properties
•Enhanced human health and wellbeing
Conventional design
•Not all interactions addressed
•Additional costs incurred or lower
quality obtained (red zones)

Urban adiabatic cooling – particular selection
of deciduous threes with high leaf surface area
- existing - Carpinus Betulus, Catalpa bignonioides, Acer
sp., Juglans nigra, Platanus sp
- new - Liqiudambar sp.
Passive heating - threes that loose leafs first
week in October
- Acer platanoides, Alnus glutinosa,
Winter wind barrier - evergreen threes
-existing - Picea abies, Taxus baccata,
Pinus sp., Pseudotsuga sp.
-new - Pinus nigra, Thuja columnaris,
-Juniperus communis „Hibernica“
Semi open space - for social activities
central zone threes - high treetop( 3-4m)
- Celtis Australis, Rhustiphina, Betula verrucosa
