Periodic Report Summary 2 - STREAMER (Semantics-driven Design through Geo and Building Information Modelling for Energy-efficient Buildings Integrated in Mixed-use Healthcare Districts)

Project Context and Objectives:
Both in terms of societal as well as environmental impact, the healthcare buildings sector plays a key role as the world faces demographic and climate changes. Ageing population aged over 60 years will be nearly tripled, leading to major increase in the number of potential patients. This phenomenon places the healthcare building sector among the top EU priorities; it plays a key role for a sustainable community. However, their energy use and carbon emission are among the highest of all building types. In order to cope with the energy, financial, political, societal and environmental crises, all healthcare districts in Europe are seeking to substantially reduce their energy consumption and carbon emission by 30-50%. Therefore, they are planning new energy-efficient building projects as well was energy-efficiency retrofitting of the existing buildings. There is a strong need of a breakthrough in designing energy-efficiency buildings integrated in the healthcare districts.
STREAMER is an industry-driven collaborative research project on Energy-efficient Buildings (EeB) with cases of mixed-use healthcare districts that aims to reduce the energy use and carbon emission of new and retrofitted buildings in healthcare districts in the EU by 50% in the next 10 years. Such districts are the best real examples of neighborhood with integrated energy system consisting of mixed building types (i.e. hospitals and clinics; offices and retails; laboratories and sport facilities). The main objects are:
- To substantially optimize the energy-efficient design of both new and retrofitted buildings in the healthcare districts.
- To provide the multidisciplinary design teams with advanced design tools by improving the open interoperability between the Building Information Modelling (BIM) and Geographical Information System (GIS) in a Sematic Web (SW) environment, and by enabling model-based analysis of the energy performance.
- To effectively manage information flow, knowledge integration, communication and design-making in the participatory semantics driven design process according to the principles of the Integrated Project Delivery (IPD).
The STREAMER results will be validated in 4 projects involving the Implementation Communities. The outcome will be used to extend the standardization in EeB design and operation, open BIM-GIS (IFC-CityGML), and Integrated Project Delivery (IPD).

Project Results:
The STREAMER project approaches its goals through process and methodology; and tools and technology.

WP1 has created overviews of design topologies and their relation to energy efficiency. One important result is the concept of Semantic Labels. These labels enable a design team to attach a rough indication of relevant values to rooms, based on a Program of Requirements. An additional benefit of these Semantic Labels is that they enable design rules, capturing the architects’ knowledge and best practices.

WP2 has achieved results in investigating the possibilities of MEP (Mechanical Electric and Plumbing) systems, HVAC and facade technologies. This led to an extensive overview of these systems, their applications and impact on energy efficiency. The Semantic labels concept also helps here because it guides the choice for MEP systems in the early design, narrowing down of choices for HVAC, MEP and facade technologies.

One key result of the STREAMER project is created by WP3, the Decision Support Tool (DST) that enables design teams in early design stage as well as later stages to assess and compare different design alternatives. This tool plays an important role in the Participatory Design Process as defined by WP4. The DST is able to read the outputs of tools, and processes these to be displayed in the form of Key Performance Indicators: energy, cost and quality. For early design, energy calculations are implemented according to CEN norms; using default values related to Semantic Labels to assess the energy demand of a design.

The participatory design process (created by WP4) was tested in a number of design workshops that were organized by pilot hospitals (in WP7). Here, stakeholders that were not yet related to the project, used prototypes of the STREAMER tools according to the process defined by WP4. Based on these workshops, important feedback was gathered. WP4 has assessed the suitability of the IPD (Integrated Project Delivery) approach for energy efficiency. Additionally, WP4 has laid out and implemented approaches to uncover tacit knowledge of architects and other stakeholders; formalized in Design Rules using Semantic Labels.

WP5 provides supportive results like the ReqCap tool that checks whether or not the exchanged BIM files (in IFC format) contain the right information. Thus this tool contributes significantly to the quality and dependability of the STREAMER workflow.

One very visible result of STREAMER that already has attracted much interest from the Implementers Communities is the Early Design Configurator of WP6. The idea of the EDC is based on the necessity to evaluate different design alternatives. It is time-consuming to create these manually; the EDC takes the Program of Requirements, the building outer shell and the Design Rules as input and creates an optimal design. Different design alternatives can be created and evaluated. The Design Validator checks to what extent the Design Rules have been respected. The Design Rules themselves can be managed through the Knowledge Editor.

In WP7 all results from the previous work packages are evaluated in practice; and the other way round, many requests, ideas and insights from WP7 were fed back into the other work packages. WP7 is an important ‘sanity check’ for the STREAMER work. For instance, based on feedback from the design workshops and reactions from the pilot hospitals, in the last period of STREAMER more attention will be given to refurbishment projects.

In WP8, for dissemination the results can be seen in a number of papers and conferences. For instance the EeB cluster workshop in Brussels, the Sustainable Places 2016 conference and the ECPPM 2016 conference. The exploitation is monitored by keeping track of the Key Exploitable Results, which is put on the agenda during each General Assembly. Standardisation as an activity has started prior to M36.

Potential Impact:
The STREAMER results are validated in the 4 projects involving the Implementers Communities: NHS Rotherham (UK); The Rijnstate hospital (NL); The University Hospital Campus of Careggi (IT); The Assistance Publique – Hospitaux de Paris (FR).

Expected main results
The expected main results are:
- Parametric design solutions for a range of building types that can be configured and validated for each unique project.
- Improvements in buildings design in order to facilitate decision-making before the construction which results in a greater ability to positively impact project costs and functions..
- Guidelines, best practices and approaches for improved participatory design, where the interests of all relevant stakeholders are combined, making use of dedicated tacit knowledge.
- Extensive overviews of MEP, HVAC and Facade EeB technologies that allow optimal choice of these systems.

Targeted impacts
Specific impacts:
- The Rotherham NHS Foundation Trust participates in the NHS Carbon Management Programme. The 5 year Carbon Management Plan (CMP) targets 30% reduction in building related carbon emissions.
- Energy-related investigation within the Rijnstate hospital will be performed in synergy with the on-going EU project RES-Hospital, which focuses on new systems at building and neighborhood scales based on renewal le energy sources.
- Emission reduction per year for the new healthcare district of AOU-Careggi Firenze will have a reduction per year by 180 tons of sulphur dioxide and 24 tons of particulate matter.
- The targeted real impacts for the University Hospital district in Paris (AP-HP) is a considerably lower annual energy bill.
Generic impacts:
- 50% reduction of energy consumption of healthcare districts in the next 10 years.
- Validated design decision, taking into account the lifecycle energy performance of buildings and neighborhood.
- Fragmentation in problems in design are resolved; continuity in information flows.
- Active participation of industrial partners; market competitiveness of SMEs.
- Sustainable transformation of healthcare buildings and neighborhoods in EU.
- Contribution to EC EeB – PPP, Horizon2020.

Targeted use / exploitation
The knowledge dissemination and valorization towards the exploitation of projects results will take place in and through the Implementers Community (IC).
The STREAMER results (TRL 6-8) will be exploited from individual product development to market and value chain integration in the field of EeB. We expect that all energy efficiency goals can be met by clients making use of the STREAMER results.
The results will be further developed after finishing the project. The exploitation model will use the contributions of launching customers and development partners.

It can be noted that a number of STREAMER partners that fall in the SME category, have become very active on the exploitation possibilities of the STREAMER results, especially the tools.
Partner AEC3 has created the ReqCap tool for BIM Quality Control and expects wider use for this tool; it is not hospital-specific so wider use in the construction sector is logical.
Partner DMO has been able to significantly improve their existing product RE Suite, turning it into a full Decision Support Tool.
Partners DJG and IAA have adopted the Semantic Labels and Design Rules methodologies; they already reported additional turnover because of the STREAMER results.
Partners BEQ and DWA advice on MEP and energy matters; through the Implementers Communities they have an extended platform.
Additionally, it is relevant to note that partners DMO, KIT and DJG have assessed the possibilities for a deepened elaboration of the Early Design Configurator and related tools, based on the feedback given in the Implementers Communities; the market expectations for this toolset are expected to be interesting enough to justify additional investments.
