Context & Agenda of the SP2016 DISTRICT RENEWAL Workshop:

“INNOVATIVE TOOLS AND SYSTEMS FOR INCREASED PARTICIPATION IN DISTRICT RETROFIT & RENOVATION”

The design of retrofitted efficient buildings and districts must involve all stakeholders within a collaborative approach that allows the delivery of cost-effective solutions. This is only possible through improved planning and design processes – as IPD paradigm prom-ulgates – and requires consistent and error-free data sharing, proper training of stake-holders and overcoming a number of technical barriers occurring in the current state-of-practice. Among them are: in-existence of proper tools for holistic planning for district re-furbishment; lack of interoperability among existing tools; limited access to reliable mate-rial and equipment data bases; gaps and improvements needed in emerging technolo-gies such as Building Information Modelling (BIM). All these concerns make software vendors and stakeholders reticent to invest in the development of interoperable tools and workflows. Thereby expected benefits both with respect to cost and quality of the end product designs are not realised. And apart from technical and industrial barriers, other ones related to economic, societal or organisational issues appear

Three European H2020 funded projects, OptEEmAL, NewTREND and Ecodistr-ICT, will work to overcome such barriers joining forces in this workshop to show how they will ap-proach this scenario and will dedicate two specific discussion round tables with a panel of experts of the projects in order to exchange experiences and benchmarking focused on some important aspects tackled on the three projects, the data integration and in-teroperability and the performance evaluation speaking about indicators and tools used to reflect the performance in energy, environmental or economic terms among others.

“Optimised Energy-Efficient Design Platform for Re-furbishment at District Level” [www.opteemal-project.eu]


Introduction

OptEEmAL, a project funded under the European Union’s Horizon 2020 research and inno-vation programme, will develop an Optimised Energy Efficient Design Platform able to design energy efficient retrofitting projects that are based on different energy conservation measures to improve the behaviour of a district. The tool will reduce time delivery and uncertainties and result in improved solutions when compared to business-as-usual practices. Under the coor-dination of Fundación CARTIF, 13 partners from 8 countries are working on delivering an op-timised, integrated and systemic design tool based on an Integrated Project Delivery ap-proach for building and district retrofitting projects.


Mission and Objectives

The main project objective – the development of an Optimised Energy Efficient Design Plat-form to improve the energy behaviour of a district – will be achieved through a mix of devel-opment and testing activities, including:


1. Developing a holistic and effective services platform for District Energy Efficient Retrofit-ting Design, which integrates interoperable modules and tools that are able to provide ser-vices for diagnosis and generate and optimise scenarios (according to stakeholders priori-ties) on criteria such as energy, cost, environment or social evaluation for data export.


2. Reinforcing the commitment of all involved stakeholders through an Integrated Project Delivery approach that allows them to articulate their needs through a collaborative and value-based process to deliver high-quality outcomes.


3. Creating an integrated ontology-based District Data Model that will contain key infor-mation in the fields of energy, comfort, environment, economic, social wellbeing and ur-ban morphology.


4. Cataloguing Energy Conservation Measures including technical, operational, mainte-nance and cost information providing valuable and consistent outputs to the design and district operation and maintenance stages.


5. Developing an optimisation module with the aim of automating the decision making pro-cess to obtain the optimal design for an energy efficient retrofitting plan at district level.


6. Externally connecting the OptEEmAL Platform to relevant entities (i.e. existing tools ena-bling the calculation of indicators to generate and optimise the retrofitting scenarios); andS
trategic dissemination, training, exploitation and market deployment of the project’s devel-opments and results.

Impact


The Optimised Energy Efficient Design Platform will create the possibil-ity for stakeholders to receive an optimised, integrated and systemic de-sign for their retrofitting projects of buildings or entire districts.
This leads to impacts on different levels:
 Economic impact through the reduction of costs during the design phase by 19% compared to business-as-usual. The costs of the op-erational phase are reduced by 25% by promoting holistic solutions, leading to a higher Return on Investment.
 Increase of market competitiveness through the utilisation of energy efficient solutions in a holistic integration and the improvement of the contractual processes.
 Growth of the European construction sector through the creation of new jobs and strengthening SMEs in the sector.
 Social impacts by the involvement of inhabitants in the decision mak-ing process. This ensures that their expectations are met, increases user acceptance of the activities carried out and will finally lead to an improvement of social wellbeing.
 Fostering the dissemination of the new knowledge at professional level through specific information channels and actions targeting the relevant stakeholder groups.

Validation of the Platform in Demonstration Sites


In order to validate the OptEEmAL platform, two steps are required: 1. Testing of the platform prototype in existing EU-wide energy efficient retrofitting pro-jects at district level.
A wide spectrum of case studies will be selected, ensuring performance is tested under differ-ent conditions including climate aspects, boundary conditions, uses, building typologies, levels of intervention, conservation conditions, existence of specific barriers, consideration of histori-cal buildings, etc. Six case studies have been pre-selected so far in four different countries with others expected to join:
 Sweden
 Turkey
 United Kingdom
 Spain (three different case studies with different uses, typologies and climatic conditions).

In an ambitious final stage for the validation procedure, OptEEmAL will be used by real stakeholders to carry out energy efficient retrofitting design projects for three dis-tricts.
Three different stakeholders in charge of designing retrofitting projects at district level are es-sential to become test-beds for validation: A municipality, a private consortium of technical of-fices and a municipal company. Each will head the demonstration of the performance, useful-ness and user-friendliness of the tool for developing Integrated District Energy Efficient Retro-fitting Plans in real environments. The final stage for the validation procedure will be carried out in three demo cases:
 San Bartolameo, Trento (Italy)
 Txomin Enea, San Sebastián (Spain)
 Polhem Area, Lund (Sweden)

Partners


The OptEEmAL consortium consists of 13 partners from 8 countries (Spain, France, Italy, Greece, Turkey, Germany, Ireland and Sweden), each one contributing specific knowledge to meet OptEEmAL objectives, according to their role in the project. The project partners represent key stakeholders within the value chain of the retrofitting design process of build-ings and districts (research institutions, large industries, small and medium enterprises, including technical offices representing the final user, public authorities, and an exploitation and dissemination/communication expert partner).

Workshop Co-chair: NewTREND

Introduction


NewTREND seeks to improve the energy efficiency of the existing European building stock and to improve the current renovation rate by developing a new participatory integrated design methodology targeted to the energy retrofit of buildings and neighbourhoods, establish-ing energy performance as a key component of refurbishments. The methodology will foster collaboration among stakeholders in the value chain, engaging oc-cupants and building users and supporting all the refurbishment phases through the whole life cycle of the renovation.Th
e methodology will be supported by an online platform to ease collaborative design, which will play the role of exchanging information and facilitating dialogue between the different stakeholders involved in the retrofit process. It will store all the information useful to the design of the retrofit intervention in a cloud based interoperable data exchange server, i.e. the District Information Model server, which has the ability to and export multiple file formats thanks to se-mantic web technologies.A Data Manager tool will be developed to guide the designers in the data collection phase, which might be a complex task for retrofit projects where information and drawings are scat-tered or even not available.


The NewTREND platform will be a tool for collaborative design allowing evaluation of different design options at both building and district level through dynamic simulations via a Simulation & Design Hub. Design options, including district schemes and shared renewables will be presented to the design team, together with available financing schemes and applicable business models, in a library which will build on lessons from past and ongoing R&D projects.

The NewTREND methodology and tools will be validated in three real refurbishment projects in Hungary, Finland and Spain where the involvement of all the stakeholders in the design process will be evaluated and specific activities will be dedicated to inhabitants and users.

Objectives


Integrated Design Methodology—Including a guided process through all steps of refur-bishment from concept to operation and a decision process for the selection, design and op-timisation of retrofitting solution for buildings in their neighbourhood context

Participatory Design-Focus on all stakeholders (including inhabitants and building users) in the design process, through pre-design multisession community design charrettes, review dialogue in the construction phases and post-occupancy evaluation workshops

Collaborative Design Platform-Ensuring the correct implementation of the Integrated De-sign Methodology through a project management infrastructure, a user friendly GUI custom-ised to the stakeholders, including visualisation and participation options

District Information Model-Interoperable, distributed, multi-model data exchange server to store information on energy efficient design and integration with neighbourhood energy sys-tems, linking existing data model formats at building and district levels

Data Manager-Enabling a structured, standardized crowdsourced data collection approach through a web-based tool accessible from tablets and smartphones, supporting design teams in on-site inspections and direct data entry in the DIM

Simulation and Design Hub-Cloud-based platform to evaluate retrofitting needs, guide the decision makers to select the best energy retrofitting strategy, balance the building in its dis-trict, through Dynamic Simulation Modelling, GIS, KPI and optimisation tools 

One of the key concepts exemplified by the figure below is the presence of roughly two groups of scales, or levels, according to the type of theme assessed: The interaction level, where production, consumption, and access can be analysed. It can be studied from a bottom-up per-spective and appears typical of buildings and blocks; The distribution level, where infrastruc-ture, networks, and supply systems can be analysed. It can be studied from a top-down perspec-tive and appears typical of districts and cities.

The NewTREND project, in keeping with the cur-rent multi-scale sustainability approach, will thus consider environmental, social and economic themes to analyse the sustainability performance of a building within its neighbourhood, and the overall performance of the neighbourhood (or district) itself.

Project Introduction

The ECODISTR-ICT project is funded by the European Union through the Seventh Framework Programme. It is coordinated by VITO and involves Arup, Bipolaire Ar-quitectos, CSTB, Omgeving, Sigma Orionis, SP, Strusoft, TNO, VABI and White.The ECODISTR-ICT project aims at developing an integrated decision-support tool that facilitates decision making on the retrofitting and renewal of existing districts and their composing buildings.It will connect the main decision makers in urban district transformation programmes, acting from different perspectives, with different time scales, to reach a coordinated approach that joins building retrofitting with district renovation.It will provide trustworthy insights on (i) retrofitting and renewal projects, (ii) the asso-ciated costs and benefits over the life cycle of the buildings, and (iii) the impacts on resource efficiency, social aspects, indoor and outdoor quality of buildings and dis-tricts, and other environmental concerns.The ECODISTR-ICT tool will be tested in five demonstration sites located in Belgium, Sweden, Spain, the Netherlands and Poland.

Outcomes


ECODISTR-ICT will develop an innovative decision support tool to assist district renovation planning, inte-grating the needs of different stakeholders: inhabit-ants, local authorities and business investors. The tool will give the opportunity to select stakeholders’ highest priorities and report building renovation scenarios. The tool will specifically assess related costs & bene-fits, as well as environmental & social impacts at a district level. Although energy efficiency is a major fo-cus, the software environment will include as many aspects as possible in its modular platform structure.

Ecodistr-ICT Case Studies


The case studies are mainly initiated by local architecture, design and planning firms with extensive experience in the local context and everyday practice. In the case studies, we pro-vide a close cooperation with the research institutions and a broad range of local stakehold-ers.
A geographical distribution of the case studies will reveal contextual differences regarding culture, climate and policies in relation with energy-use and energy efficiency. These differ-ences will be incorporated in the development of the tool.
