BIM-Speed - Methods for architectural, structural and thermal 3D data acquisition of existing buildings

Building Information Modeling (BIM) is an efficient method, to unlock the energy saving potential of renovation projects. Therefore, the central target of the BIM-Speed project is to enable stakeholders to integrate BIM into their work process. The developed Building Information Model (BIM) is a digital representation of a building to support the renovation and asset management of existing residential buildings. Already in the run-up to the project, the consortium showed that the use of BIM comprehensively reduces time and money resources.

Overall, the aim of the BIM Speed project is to implement BIM in a holistic approach and to provide a cloud-based BIM platform that can interact with a range of BIM tools.

Demonstration Cases 

BIM-Speed solutions are tested in 13 real demonstration cases in different European climate zones. In the course of the project, various activities are carried out on the demonstration cases:

  • As-Built data acquisition and BIM modelling
  • Renovation design
  • BEM and performance simulations
  • Renovation execution (off-site and on-site construction)
  • Post-renovation evaluation and long-term maintenance planning

RenoZEB - Renovation for zero energy Vöru-Estonia

RenoZEB was created with the aim of opening up the renovation market for Nearly Zero Energy Buildings (nZEB). The focus is on the development of economical “plug-and-play” solutions, which increase the property value in a comprehensive nZEB renovation market and support all project participants through the renovation measures with further training and networking opportunities.

The project introduces the advantages of the refurbishment of existing buildings in a minimally invasive system. This procedure results in a significant reduction in the total cost of installation and construction time, as well as upgrading the property in line with energy efficiency standards.

Furthermore, the developed collaboration platform based on Building Information Modeling (BIM) supports the entire life cycle of the building renovation process. The platform functions as a central database in which the project participants can get information and network. Free technical training, workshops and web meetings will help participants discover best practices and workflows and achieve the best results for their renovation projects.

Demonstration Cases

The RenoZEB approach is tested on three real residential buildings in two different climate zones (Spain and Estonia) and three virtual buildings (Bulgaria, Italy and Greece). During the test phase the focus is on the following aspects:

  • Monitoring throughout the refurbishment process
  •  Evaluation of the Buildings in terms of energy efficiency, health and comfort conditions, cost and value including asset appreciation and
  • Development of an evaluation framework in the process

ENVISION - Energy Harvesting by Invisible Solar Integration in Building Skins

For the first time, thermal and electrical energy can be obtained from ALL building surfaces, transparent and non-transparent. That is what ENVISION makes possible, with the developed full envelope concept that aims to exploit the potential of generating solar energy from building surfaces.

The Project presents various innovations. PV solutions are for the installation on the roof, aesthetically pleasing solutions can generate energy from the façade and see-through solutions are constructed for windows. During the development, the aspects of simple installation and maintenance as well as cost efficiency are taken into account.

Demonstration Cases

ENVISION tests the innovations in the Northern and Southern Europe, what implicates under different climate conditions. This are the examined matters:

  • Possibilities of solar power generation from building surfaces and use of electricity to operate heat pumps
  • Testing power-generating see-through solutions and the ENVISION Ventilated Window
  • Performance and control of ENVISION harvesting solutions in combination with other solutions 

The energy efficiency of the individual buildings is monitored and compared with previous data of the buildings.

GEOFIT - Deployment of novel GEOthermal systems, technologies and tools for energy efficient building retroFITting 

The aim of GEOFIT is to make the use of efficient geothermal systems for heating and cooling practicable and cost-effective by introducing a new concept for building renovation. The concept is based on geo-thermal energy and small to medium-sized heat pumps. This includes several innovations such as novel hybrid heat pumps, improved low-invasive vertical drilling, advanced cloud-based and deployable control systems, and novel BIM-enabled tools.

Ultimately, the concept lowers the operating, acquisition, energy, and installation costs of geothermal systems and ensures an easy installation. GEOFIT offers many significant benefits that take geothermal systems to the next level, such as large energy savings, integration into a single system for cooling and heating, free environmental energy, high energy efficiency, long-life system and very low maintenance.

Demonstration Cases

GEOFIT demonstrates the technologies in five pilot projects in different EU-climate zones. The tests are carried out on very different building types, such as a historic building or a university campus. 

The investigations are focused on this aspects:

  • Evaluation of the LTH system using several connection scenarios with heat pumps
  • Function of Shallow earth energy bakest and a hybrid heat pump
  • Installation of hybrid heat pump and non-standard GHEX
  • Retrofitting and implementation of a geothermal system using IDDS methodology
  • Use of a geo-BIM based management

REWARDHeat – Renewable and Waste Heat Recovery for Competitive District Heating and Cooling Networks

REWARDHeat demonstrates the functionality of low-temperature district heating and cooling networks able to recover renewable and waste heat, from multiple sources diffused within the urban context. These networks will be able to increase production and distribution efficiency by recovering, renewable and waste heat available at low temperature. For this purpose, a new prefabricated district heating substation including heat pump, storage, actuators, and control platform allowing bidirectional exchange of heat with low- and neutral-temperature DH networks is being developed. The designs also reduce manufacturing and capital costs.

To achieve the main goal, REWARDHeat has several sub-goals. This includes the effective integration of renewable energy sources and waste energy sources. Furthermore, the development of innovative technologies enables flexible use of heat in DHC networks. Aspects of digitization and the profitability of innovations are also taken into account.

Demonstration Cases

The technology is being tested at 8 pilot sites. The following aspects are examined:

  • Demonstration of moving from a high temperature DH network supply to a low-temperature DH network supply
  • Exploitation of local waste heat potential from industry
  • Implementation of hardware/software for smart monitoring and control
  • Developing business models adapted to the local context
  • Retrofit of an existing District Heat Networks
  • Utilisation of decentralized PV panels combined with multiple storage solutions
  • Creation of an island solution independent of existing DH network
  • Establishment of a space targeting the general public, equipped with media installations, which illustrate the real-life applications of REWARDHeat solutions on guided tours
  • Testing new storage and energy management strategies
