Abstract

Reducing the energy consumption in the tertiary sector is an objective towards net-zero carbon cities In this regard, governments have set ambitious legislation to drive the real estate actors to renovate their building stock. In 2019, a French decree on the obligation to reduce final energy consumption in service sector buildings requires both landlords and tenants to implement actions to reduce energy consumption by 40% by 2030. As there is shared responsibility on the management and use of the building, a strong collaboration between landlords and tenants is necessary to achieve these energy objectives. This paper analyses a stakeholder engagement process between landlords and tenants to respond to the decree, as the two actors have access to different energy data, ways to collect it, and responsibilities to comply. The engagement process aims to increase the response rate for energy data collection. Based on a communication plan that targeted the landlords and tenants of over 1000 buildings (approximately 8 million m2), a difference in response rate between the different typology of users (single and multi-tenants’ assets) was observed. The results highlight the challenge to get stakeholders on board, fully understand their role and responsibilities and the need for continuous engagement between the parties. Nevertheless, it was observed than an appropriate communication and awareness raising campaign can increase the data collection response rates by 80%.

Highlights

  • Stakeholder engagement has become an important strategy to address multiple parties with different knowledge levels or support roles

  • “Obligations to reduce final energy consumption in service sector buildings” requires landlords and tenants of buildings, parts of building and building complexes over 1 000 m2 to implement actions to reduce final energy consumption by 40% by 2030, 50% by 2040 and 50% by 2060 compared to a reference year up to 2010

  • At the beginning of the data collection process, challenges were determined as a result of a preliminary analysis based on an information campaign, using different communication channels, such as mails and calls

Summary

Introduction

Stakeholder engagement has become an important strategy to address multiple parties with different knowledge levels or support roles. This type of engagement is mostly observed, and required, in urban-scale projects where community stakeholders need to be involved. In November 2018, the law n°2018-1021 concerning Evolution of Housing, Development and Digital, was adopted in France This law set up new guidelines in order to build more, better and less expensive building, develop social housing, encourage social diversity and enhance the living environment [6]. In line with these ambitious legal provisions, the decree n°2019-771 of 23th July 2019 on Manuscript received 31 August, 2021; revised 14 December, 2021; accepted 5 January, 2022; published 19 January, 2022
