MartiniPlaza, The Netherlands

MartiniPlaza in Groningen is amongst the top event centres in the Netherlands with a large theatre, exhibition space, basketball arena, conference rooms and more. RES4BUILD is collaborating with the MartiniPlaza and its stakeholders, including the Municipality of Groningen, on a long-term vision for the complex aiming at net-zero emissions, as well as a short-term package to achieve low-emission objectives. The project team has set up two workstreams:


  • - The Long-Term Action focusses on the vision to be realised in ten years. By this time, the three core blocks of the building (the theatre, exhibition centre and sports hall) will have to comply with sustainability standards or labels for energy performance for buildings. This will be done both by retrofitting or replacing building blocks. RES4BUILD are exploring the co-creation process with stakeholders such as the Municipality of Groningen, the MartiniPlaza and users/clients, towards developing this vision.
  • - The Short-Term Action aims at identifying energy saving measures with a payback time of less than ten years. The RES4BUILD team is discussing technical options as well as exploring co-creation processes so that potential solutions are not only technically feasible and economically viable, but also acceptable within MartiniPlaza’s community of stakeholders.

The results from both workstreams are expected by May/June 2022 and will be included in the case study report in Work Package 4 of RES4BUILD.

Cultural Centre Zuidhorn, The Netherlands

Cultural Centre Zuidhorn (CCZ) is a community centre hosting: a music school, theatre, arthouse movies, workshops and lectures. RES4BUILD is collaborating with CCZ to develop a joint vision on the building energy performance, with a focus on comfort and ways to make energy consumption more sustainable. For that, RES4BUILD’s team undertook the following actions: 


  • - All building users as well as daily management staff were invited, from February to March 2021, to complete a questionnaire on how they perceive the energy performance of the building, how energy service and payments are covered in their tenant contracts, and how installation malfunctions and comfort complaints are handled.
  • - An indoor environment performance review was completed from April to June 2021, which is a technical analysis of what equipment is available for heat, electricity, cooling and fresh air, and what the potential performance gaps are. This resulted in two recommendation lists: one of ‘low hanging fruit’ measures that could be done in the short term, and the other containing more substantial energy performance improvements. The latter solutions, including those from RES4BUILD project, could be considered in case of a future retrofit of the building.
  • - A stakeholder meeting was held in September 2021, including building management and owner (the municipality) to discuss the solutions, as well as how all collaboration could be improved for more inclusive decisions on energy performance.

A report on the above steps will be included in a report for RES4BUILD (Deliverable 2 of Work Package 4).

Royal Visio (Koninklijke Visio), The Netherlands

Royal Visio is an organisation that provides health care for visually impaired clients, who sometimes have other physical and/or mental impairments. With over 1,600 employees and 17,000 plus clients Visio is a sizeable health care organisation with around 300 locations, buildings. A range of conventional procedures and resources are already in place to effectively manage the energy portfolio of their buildings. Despite this, a key challenge is to ensure a timely upgrade of the energy performance of their entire real estate portfolio in line with 2030 and 2050 energy and climate goals. This challenge has a technological, financial as well as social dimension which goes beyond the level of energy renovation of a single building.


RES4BUILD partners JIN and ARUP are supporting Royal Visio on their journey to develop a strategic approach for implementing integrated energy systems (IES) in their entire building portfolio, using a site in Vries as a case study. With around 50 buildings concentrated in one location and forming around 25% of Royal Visio’s total gas and electricity consumption, this site is ideal for field testing a more strategic approach to sustainable and integrated real estate asset management in the health care sector. 


ARUP and JIN will provide Visio with information and guidance on the different technological ‘routes’ for implementing IES systems, as well as exploring which combinations of traditional and novel financing options are available in the health care sector. On top of that, different modalities on how to engage/involve with clients, staff and external stakeholders will be presented, all in an effort to move towards a more structural and integrated approach.
