The Future of the Past is a biennial conference generally carried out during the commemoration date of the incorporation of Santa Ana de Los Ríos de Cuenca Ecuador as a World Heritage Site (WHS). It initiated in 2014, organized by the City Preservation Management research project (CPM) of the University of Cuenca, to create a space for dialoguing among interested actors in the cultural heritage field. Since then, this space has served to exchange initiatives and to promote coordinated actions based on shared responsibility, in the local context. The third edition of this conference took place in the context of the 20th anniversary of being listed as WHS and a decade of CPM as the Southern host of the PRECOM³OS UNESCO Chair (Preventive Conservation, Maintenance and Monitoring of Monuments and Sites). For the very first time, and thanks to the collaboration with the Raymond Lemaire International Centre for Conservation of the University of Leuven (Belgium), the conference expanded its local scope. On this occasion, contributions reflected round a worldwide challenge in the cultural field: revealing the paths towards participatory governance of cultural heritage. Participatory governance is understood as institutional decision-making structures supported by shared responsibilities and rights among diverse actors.

The concept of preventive conservation has successfully introduced the knowledge that "prevention is better than cure" into the built heritage sector. The benefits of this approach are the cost-effectiveness, the improved protection of heritage values, the reduced risk for accumulating deterioration and additional damage, the prolongation of the physical service life of buildings and building parts and the empowerment of local communities in dealing with heritage. Increasingly, arguments rise against reactive treatment patterns, which result too often in postponed interventions and increasing costs for restoration. WTA-Nederland-Vlaanderen, the Raymond Lemaire International Centre for Conservation and the Civil Engineering Department of KU Leuven jointly organised an international conference on preventive conservation approaches - including climate and damage monitoring - and how to implement these monitoring tools within a systemic approach. The conference took place in context of the international WTA days, 3-5 April 2019, and the 10th anniversary of the UNESCO Chair on Preventive Conservation, Monitoring and Maintenance of Monuments and Sites (PRECOM(3)OS). The contributions meet the increasing demand for information, case studies and practical examples to support the transition towards more preventive rather than reactive conservation actions. The volume aims at academics and professionals involved or interested in the conservation of buildings, building parts and heritage.

Professionalism entails the conduct, aims and qualities that characterise a profession. The term is also used to describe education and training standards for the knowledge and skills necessary to perform a specific profession. In practice, professional standards of practice and ethics are agreed upon and maintained by recognised associations. In the past, professionalism has not occupied a central place in built heritage discussions, policy and research. Recent changes in terms of public attitudes and sustainability concerns have had a cumulative impact on the requirements for professionalism in the built heritage sector. The future success of the sector will depend on the availability of adequate professionals and an appropriately skilled workforce. In practice, the built heritage sector involves much more than interventions to conserve, preserve, rehabilitate or restore a heritage structure. Bringing a project to fruition begins with the formulation of a policy, proceeds to the design and execution of intervention strategies and ends with ongoing maintenance of heritage structures and related future programming. This process requires sufficient interactions between different professionals to obtain a common vision and hold that vision throughout a project. At the same time, the sustainability of the sector is also defined by effective governance, societal support and cultural rationales. Professionalism in the Built Heritage Sector contains reports on the lectures of the international conference organized by the Raymond Lemaire International Centre for Conservation (Leuven, Belgium, February 5th-8th, 2018). The contributions in this volume meet the increasing demand for shared information to support the transition towards a more sustainable conservation process. The volume consists of three main parts that deal with practice-led research or scientific research: "Profiles and capacities", "Education, training and quality labels", and "Obstacles and changes".

Several international and European institutions have given increasing importance to sustainable approaches to our existing building stock and the role of built heritage in this process. At the same time, preventive and planned conservation of built heritage has been increasingly recognised by researchers given its cost-effectiveness for owner-managers, effective long-term quality protection and environmental enhancement of structures, as well as its potential of activating heritage in the employment sector and empowering of local communities. 'Innovative Built Heritage Models' collects the lectures presented at the international conference on CHANGES (2017 Thematic Week, Leuven, Belgium, 6-8 February 2017). The aim of the conference was to provide an international overview of the existing strategies, processes and operational case studies that support the implementation of a preventive and planned conservation approach in the built heritage sector. The conference twins with the 'CHANGES' project, supported by the Joint Programming Initiative Heritage Plus programme. This publication meets the increasing demand for shared information to support the transition towards a more sustainable conservation process. The volume consists of three main parts: 'The CHANGES paradigm', 'Preventive and planned conservation' and 'Case studies of Change'. The book reflects on CHANGES in a straightforward manner by providing research and case studies that serve as baseline records, guidance and essential literature for researchers and practitioners involved in the built heritage sector.
