Periodic Report Summary 2 - DESIGN4ENERGY (Building life-cycle evolutionary Design methodology able to create Energy-efficient Buildings flexibly connected with the neighborhood energy system (Design4energy))

Project Context and Objectives:
Design4Energy project aim to develop an innovative Integrated Evolutionary Design Methodology that can allow the stakeholders to predict the current and future energy efficiency of buildings (both at individual level and neighbourhood level) and make better informed decision in optimising the energy performance at building life cycle level, including operation and maintenance.

The proposed methodology will be based on a sophisticated technology platform that will make use of energy attributes of building components and systems, neighbourhood energy systems, energy related parameters, energy simulation tools and current usage parameters of the tenants , derived from maintenance and operation data. The technology platform developed within the Design4Energy project will allow the stakeholders to explore various design options and make validated and qualified choices as early as possible, giving due considerations to regulations, user comfort, constraints, and future evolution of the building over time.

The main objectives are:
• Develop Information platform to connect Design process with neighbourhoods and grids configuration, predicting relevant information of building performance in early design stage which could be use for future energy matching and performance optimization.
• The Design4Energy platform will work with current building context and will allow the creation of evolutionary scenarios by offering different information of adjacent energy systems.
• The Design4Energy platform will allow the creation of evolutionary scenarios that take into account the technological evolution of building materials, components and energy systems.
• Development of Information Platform that supports the optimized design of integrated energy-efficient buildings using a holistic approach to estimate energy consumption in buildings from the initial sketch of the building until the end of its service life.
• Deep analysis of the perception of the users of the building about comfort and user behaviours.
• Development of a decision support tool that will suggest the most accurate design options to increase the building energy efficiency.
• Creation of a virtual workspace that will allow the actors to interact with the buildings and explore “what-if” scenarios to create energy efficient buildings. It will support distributed team support for stakeholders.
• Development of a complete interoperable data exchange protocol among design platform, the energy model module, and other information systems, facilitate the building designer in getting building performance during the early design phase.
• Contribute in IFC development and connection with status-of-the-art energy simulator.
• Create the interoperability suite which implement the defined data exchange protocol, facilitate the conversion of gbXML and IDF format.
• To validate the Design4Energy methodology in three demonstration buildings with different use and different climate conditions, in order to demonstrate the adaptability and replicability of the new methodology.
• To develop a virtual e-learning environment, based on the gaming technology that can allow people to learn how to design green buildings taking a more holistic view of the building life cycle.
• To train different stakeholders and offer an easy-to-use Guidelines for architects, SME builders and decision makers to enhance the use of integrated solutions.
• To contribute to bridge barriers for implementing of Integrated Energy Efficient Project Delivery (IEEPD) concept as a main instrument to fulfil with the EPBD-2010/31/EU as one of the main European Policies.
• Dissemination Plan and its deployment to facilitate the Social acceptance.
• To develop new business model considering the innovative schemes based on Energy Efficient Buildings and Low Carbon Urban District concepts and the emerging innovative technologies including Design4Energy outputs.

Project Results:
Based on the work plan established in the Kick-off meeting, activities and tasks were started earlier than planned in the DoW. To conduct the technical development, 3 usage scenarios were created and common understanding was built after several meetings:
1. Focus on the influence of the neighbourhood on the building design.
2. Focus on the design exploration during early design stage for new built.
3. Focus on retrofit buildings. Use the operational and maintenance data to explore new improvement options.
During the 2nd project period, the three scenarios and Design4Energy methodology were continuously refined and further developed. The technical development was oriented to the implementation of the scenarios and tools development and integration based on the 1st prototype demonstrated in the 1st review meeting in M21. gbXML and IFC has been defined as the key links of building model and energy model, three approaches were defined to demonstrate the Design4Energy concept and methodology:
(1) Use Design Builder as a middleware to convert gbXML into IDF (input of the energy simulator EnergyPlus);
(2) Continue our development of gbXML-IDF converter;
(3) Connect eeBIM with EnergyPlus using IFC, extend and integrate eeBIM.
Data flows of the three approaches have been developed and implemented. Tools identified in the process maps were continuously developed and improved.

Design4Energy tools will provide more accurate and reliable instruments to visualize the future building performance, along with a decision support tool able to select the best alternative with compliance with regulation and user-oriented comfort expectations and constraints. By address the building performance in the early design phase, it is expected to further improve the energy efficiency and achieve significant reductions in energy use and CO2 emissions.

2. Strategic Impact
Design4Energy will contribute to behavior change in energy efficient building design by pushing the designer to consider the performance issues in early design phase, facilitating and improving the conversation between building designer and building owners, provoke the energy related conversation in early design phase. Design4energy will also contribute to increase the awareness and the confidence in Energy Efficient Buildings and the creation of new scenarios of business. Design4Energy will also contribute to raise the ICTs based customized EeB solutions.

b. Rising of environmental consciousness: Introduction of Design4Energy systems in design and construction sector will have a large impact in making designers and consequently their clients more environmentally conscious and will trigger them to adapt their behaviour.
c. Design4Energy will contribute to optimize the capital investment, the development of energy efficient buildings by providing new Design tools able to:
• Reduce the risk, improving the accuracy of estimated present and future energy performance, matching with the energy saving targets and the user requirements.
• Initialize the conversation and consideration of energy efficiency in early design phase, so to reduce the cost in future modification in detailed design phase which is normally complicated and expensive, and enable the building owner or client to have better informed decision making.
