Scope
Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: An increased number of local authorities systematically identify and quantify vacant, obsolete or underutilised spaces for reuse in neighbourhoods [1] in a context-sensitive way to address local community [1] challenges and needs. Increase in renovated, renatured, or converted spaces that address local community challenges and needs. Scope: Europe’s housing needs, inefficient use of the existing building stock, environmental commitments, and the EU’s goal of “no net land take” by 2050 make a compelling case for reusing the significant number of existing spaces, including buildings and infrastructure, that are vacant, obsolete or underutilised. In Europe, there are, for instance, an estimated 19,000 km² of underutilised brownfield land and 300 km² of vacant or underutilised office space [3] . The reuse of vacant, obsolete or underutilised spaces, following circularity [1] and sufficiency principles, can help address community challenges and needs thanks to their typical proximity and connection to essential infrastructure and services. While vacant, obsolete or underutilised spaces are already being renovated, renatured or converted, this happens typically at individual scale or for temporary reuse. A systematic and context-sensitive approach is required that maps vacant, obsolete or underutilised spaces with potential for reuse and involves local stakeholders in the reuse process to address local community challenges and needs in the long term. It is also important to understand common reasons for the vacancy, obsolescence or underutilisation of spaces and challenges to their reuse, and to recognise that not all types of spaces are suitable for reuse. Factors can include, for example, building or infrastructure condition, location, and spatial or structural limitations; zoning regulations; legal barriers; lack of data; or lack of resources, funds, or incentives for property owners and public authorities to renovate spaces. In addition, certain vacant spaces might already fulfil important ecological or social functions by providing refuge to natural species as well as non-typical community lifestyles. Proposals are expected to address all of the following: Develop a systematic and context-sensitive approach for vacant, obsolete or underutilised spaces, including buildings or infrastructures. The approach must cover at least the following: Analysis of common drivers of the vacancy, obsolescence or underutilisation of spaces. Identification and prioritisa…

The mix of organisations
Who coordinated them
Coordinating an EU project is a demanding, specific job. These organisations have done it on this topic line before.
This is the shape, not the consortium. It says how many partners these projects had and what kinds of organisation were in them. It does not know whether your idea needs the same mix, who is available, who is already committed elsewhere, or how the work and the budget should be divided. Those are judgement calls on a specific proposal, and no amount of public data answers them.
Building the actual consortium — finding the partners, agreeing the roles, and writing it so it survives an evaluation — is what Scientific Network Management does. Free either way; the radar does not change if you never ask.
Get told when something changes
Most institutions find out about a call with three weeks left. We write when something opens, moves or closes that fits what you work on, with the deadline, the fit and the funder's own exclusion clauses quoted. Nothing in a quiet week. Free, and one click to leave.
Starting from the programme you are reading: Horizon Europe (HORIZON) — change it below if you like.
Leave the second box empty and you get whatever opened or changed recently, closing soonest. Fill it in and it ranks against your words instead: that is the difference between a list and a shortlist.
Scientific Network Management will send you the current list for these terms, and after that only what changes: a call that opens, a deadline that shifts, a clause that rules you out. Nothing is sent when nothing has moved. One click to stop, in every message.
One confirmation email and nothing else until you click it. No tracking pixels, no sharing, one click to unsubscribe.
Of every 100 Horizon Europe proposals
A funding strategy reads your institution's own published record against the calls that are open, and says in writing which are worth the year and which to decline, with the reason for each.

No obligation, and nothing here is conditional on using us: searching the calls stays free and asks for nothing either way.
