Developing optimal solutions to reduce energy use in shopping centres starts with identifying and analysing inefficiencies. Getting to know the stakeholders’ needs and opinions contributes to understanding and dealing with these inefficiencies.
This report identifies technical inefficiencies as well as considers the social aspects linked to shopping centres (influence of user behaviour and decision-making practices when implementing energy renovation measures, aesthetics, comfort, safety, logistics and economy, etc.). This socio-technical approach allows actors and factors to be easily analysed and increases the chances of identifying key shopping mall inefficiencies. To do that, six relevant fields were identified and analysed, to gain as much insight as possible on the way shopping centres function, both technically and socially:
• Economic models
This report tries to answer key questions for three shopping centre stakeholder groups: owners and managers, tenants as well as customers. These groups were selected for their involvement in and understanding of the daily activities in shopping centres, not necessarily because they are associated with or interested in energy efficiency or sustainability issues.
The report is divided into four parts. The first thoroughly explains the methodology used for data collection. Tailor-made questionnaires provided data about opinions and needs associated with energy use and sustainability issues. In-depth interviews were also conducted to have an overview of the stakeholders’ motivations, perceptions, preferences or knowledge. The results have been crosschecked against the existing specialised literature. To cover a wide geographical area, the project team surveyed not only stakeholders from the participating countries, but also stakeholders from other countries. The second part of the report focuses on the social aspects of shopping centres, namely inefficiencies linked to user behaviour and decision-making practices. The behaviours of customers, tenants and managers influence the energy performance of shopping centres. The findings show that there are three areas of inefficiencies related to user behaviour:
a. Customer knowledge (or lack thereof)
b. Customer choice (influenced by different factors) and
c. The role of the physical environment.
Lack of information about energy efficiency might lessen the stakeholders’ interest in reducing energy use. Therefore, knowledge about energy-efficiency benefits and solutions is crucial. The surveys also gathered information about existing decision-making practices when implementing energy efficient measures in shopping centres. Findings show that there are differences of interests and perceptions between customers, tenants and managers. A group might prioritise factors which are less significant for another group. That is why collaboration and flow of information between all stakeholder groups are the optimal solution to achieve an energy-efficient environment and avoid user-behaviour inefficiencies.
Systemic inefficiencies and suggested solutions are described in a third part, mainly analysing lighting systems but also HVAC (heating, ventilation and air conditioning) measures, building envelopes, ergonomics and safety. Lighting is considered as the main inefficiency source in shopping centres. However lighting has the potential to achieve energy efficiency as proved in a number of shopping centres. Good planning, quality control of the complete energy system and effective use of monitoring systems are necessary for the implementation of energy-efficient solutions. The last part of the report covers the economic models used to convince tenants to invest in energy efficient solutions. The report also lists a set of recommendations to develop and implement such models. The project team investigated which economic models are used by owners and managers in shopping centres to persuade tenants to adopt energy efficiency measures. The findings show that current business models do not offer many incentives to increase energy efficiency. No standardised economic models have been identified to increase energy efficiency in shopping centres, neither in the surveys nor in the interviews.
The report’s conclusion summarises the main inefficiencies that can be associated with the European shopping centre building stock today. The causes and effects are discussed, as well as potential solutions to reduce energy use. An important step towards improving energy efficiency in shopping centres is therefore to identify the technical inefficiencies and related social aspects.
A poster summarising the results is also available.
