‘Smart’ technologies are seen as a major technological step forward with respect to improving the efficiency and effectiveness of urban systems.

Introduction

The INDICATE tool seeks to support urban planning and design decision making in an age of increasing demands and complexity. The tool will provide dynamic assessment of the interactions between buildings, energy distribution grids, renewable technologies, and ICT to provide recommendations regarding: suitable technologies to; optimum building retrofit; highlight infrastructure that requires improvement to enable local energy balancing; and identify utility services that offer the best financial return.  To understand how the decisions made will affect the overall urban environment, a set of sustainable urban indicators are being developed to measure effects from any changes made to buildings, infrastructure, or energy related technology. The resulting tool will support a holistic approach to the city and allow decision makers, planners and urban designers to:

  • PLAN using an energy-based decision support tool that utilises dynamic simulation & takes into account buildings & occupants, the urban environment & energy distribution grids.
  • REDUCE energy consumption & CO2 emissions by indicating the impact of energy conservation measures via dynamic simulation modelling.
  • INTEGRATE new technologies & services to manage supply & demand via dynamic simulation modelling, GIS & 3D urban modelling.
  • OPTIMISE existing systems to enable local balancing through demand response & tariff analysis, via dynamic simulation modelling of the interactions between buildings & their occupants, installed systems & energy distribution grids in the urban environment.

The INDICATE tool has been designed to operate any stage of development; it can be used in a city where the buildings and their urban environment are at an early stage of development or redevelopment, or to optimise existing smart grid infrastructure or efficient technologies where they have already been installed. 

To enable this level of analysis, the INDICATE tool will bring together a number of components including: simulation software developed in this project, the IES <Virtual Environment>, 3D urban CAD tools, the Esri ‘CityEngine’ software, and a suite of energy related sustainable urban indicators; to create a Virtual City Model (VCM) ready for simulation. The VCM is fed with real urban data and processes this through the components outlined to assess the impact of any proposed changes to technologies, individual buildings, or larger changes at a district level. 

 

Current Prototype Tool

 

Prototype Overview 

The INDICATE prototype developed through this project has resulted in a fully functioning tool that facilities among other things the following:

  • The creation of an interactive 3D model of an urban area that includes buildings with detailed characteristics such as building geometry, building use, number of floors, number and location of windows, and of course energy use.
  • Provides a Common City Index with 30 indicators (8 Carbon Reduction, 14 Energy Efficiency, and 8 Cost Reduction) presenting measures in relation to energy, and quantifying the impact of various interventions (e.g. the provision of PV panels, thermal insulation, etc.) 
  • Presents an interactive dashboard that can be configured to provide specific feedback in relation to selected indicators or particular project/user needs.
  • Provides an Inspector function to examine various properties of a selected building, or selection of buildings, including energy usage, building use, number of floors etc.
  • Provides the facility to create new scenes to allow the user to focus on certain elements or buildings and thus isolate specific objects for investigate or modification as part of an energy analysis exercise.
  • Carries out simulations to reflect modifications or interventions using both benchmark or simulation data.

Story Map Outlining Key Functions

A Story Map has been prepared to outline the main development of the project and to present some of the key functions using the pilot site in Dundalk, Co. Louth, Ireland as an example. The Story Map also presents a number of different scenarios to illustrate a how the tool might be used to investigate different energy interventions within Dundalk.

Please note that the tool shown in this Story Map is an Esri CityEngine INDICATE prototype.  It should also be noted that this Story Map is based on data available up to 2016, and while every effort and due care was taken to provide accurate information and data to the project, there may be anomies in some instances, which Louth County Council is not accountable for.

 

 

Web Scene Providing an Interactive Version of the INDICATE prototype tool

In addition to the Story Map a Web Scene has been created to offer users the opportunity to interact with the INDICATE prototype tool through a number of scenarios related to energy efficiency interventions in the Dundalk pilot site. While this Web Scene has limited functionality it will provide the user with a good sense of the tool and its capabilities.

Sustainable Urban Indicators

A key part of the INDICATE project involved the development of a suite of Sustainable Urban Indicators (SUI) to provide metrics in relation to energy use in the urban environment, and to quantify current conditions along with the impact of proposed interventions as part of the operation of the INDICATE tool. 30 key SUIs were selected over three categories including: 8 Carbon Reduction indicators; 14 Energy Efficiency indicators; and 8 Cost Reduction indicators.

As part of the INDICATE project, a website was created (http://energy-indicators.eu/) to provide details regarding the selected SUIs and to illustrate how these indicators are employed in the INDICATE tool. 

The website also presents a video depicting a scenario that focuses on the feasibility of establishing an urban renewable solar photovoltaic (or ‘PV’) energy system. This video also demonstrates how the SUIs are utilised within the tool to inform the decision making process.

INDICATE Scenario: Establishing an Urban PV system

The scenario shows how the INDICATE tool will calculate the appropriate urban roof area which could support the deployment of a solar PV system. The feasibility of installing renewable energy infrastructure is determined by analysing the Dynamic Simulation result, which defines the square meter roof area suitable for PV. Key indicators for this exercise include: 

•Roof Space Available for Solar PV 

•Special Heritage Status

•Energy Consumption by Type

•Building stock energy efficiency

Calculating available roof space

The scenario demonstrates various tools such as the ‘Inspector’ and ‘Selection Tool’ are used to determine how there is 648 square metres potential roof area available for solar PV on the selected residential buildings in this example.

Displaying building status

This scenario also illustrates other aspects of the tool such as how the ‘Heritage Status’ of the selected buildings can be displayed, to determine if they have a planning designation which forbids deploying solar PV panels on the structure. In this example 61 buildings in the group are recognised as having ‘special heritage status’.

Identifying target areas

The feasibility of installing renewable energy infrastructure, can be explored by selecting specific buildings determined to have the appropriate roof space in the model i.e. energy received annually by the roof space must exceed hundred kilowatt hour per meter squared. 

Selected appropriate technology

The appropriate technology application is selected from the Inspector and this intervention is then modelled on the pre-selected appropriate buildings in the scene and the simulated impact is reflected on the dashboard. By selecting two kilowatt hour PV the results of the simulation are compared with the base levels which are illustrated on the dashboard, where the total potential generating capacity of the appropriate roof space can be calculated in terms of kilowatt hours. The contrast between the baseline and the simulation data is used to explore the cost benefit of the solar PV energy system. Using the results from the tool as an indicator of energy savings, will enable the calculation of the kilowatt hour costing and compare it to the investment required.

Next Steps 

The EU funded phase of INDICATE project is complete and the post project exploitation phase has now begun. This will involve further development of the prototype towards a fully functioning and marketable tool.

When finished, it is hoped that INDICATE can contribute to the creation of more sustainable and energy efficient communities, and help support Irish and European efforts to reduce energy consumption and increase efficiency. To achieve the ambitious targets set by the EU to reduce greenhouse gas emissions by a minimum of 20%, to increase renewable energy production to 20% of consumption or more, and to achieve an overall energy savings of at least 20%, integrated and holistic planning and urban design approaches must be adopted as a matter of urgency.
