The current literature has not investigated the perceived value of energy efficiency by households, regardless of financial benefits. Furthermore, there is a severe lack of research that investigates the effectiveness of the current format of EPC-labels. Therefore, the purpose of this paper is twofold: to study how households value energy efficiency in the housing market, regardless of price effects.

This study uses multiple hedonic regression models to analyse 706,778 Flemish properties for sale or rent between 2019 and 2023. The data is provided by Immoweb – the largest online real estate platform in Belgium. Given that the selling market is driven by different mechanisms than the rental market, the data set was divided in sold (522,164 listings) and rented properties (184,614 listings).

The ambiguous results of the A-label in the selling market indicate that the “class evaluation effect” found in related markets which use labels (e.g. household appliances) is also present in the housing market. However, the results of the other (lower) labels clearly show that owners do value energy improvements within labels, and this effect becomes stronger as the EPC-label becomes better. The rental market shows the opposite results. Energy improvements are only valued if they translate into a financial benefit. Taking these findings into account, the second part of this research shows that rescaling the EPC-label creates an incentive for improvements within labels.

This paper provides novel insights by studying the perceived value of energy efficiency in the absence of financial benefits and critically studying the effectiveness of the EPC-labels in their current shape. By investigating both the sales and rental market, the authors are able to make a comparison which creates valuable insights for academia, governments and real estate professionals.

The current literature on energy certificates shows that Energy Performance Certificate labels have an important effect on real estate prices. However, interestingly, the limited studies that address the rental market find significantly lower price premiums than the sales market. The purpose of this paper is to add to this literature, by doing a comparative analysis of price premiums in the sales and rental market in Flanders (Belgium).

This study uses a hedonic regression model to analyze 177,670 real estate listings between 2016 and 2021. The data is provided by Immoweb – the largest online real estate platform in Belgium. The data set was divided in sold and rented properties: the authors evaluated 126,217 sales listings and 51,453 rent listings.

The results confirm that energy efficient properties generate a price premium, but that this premium is significantly larger in the sales market than in the rental market. In addition, the findings indicate that both investors and landlords could benefit strongly from renovating dwellings – especially when renovating from an F label to an A label.

Previous research focuses strongly on the sales market, although in many countries the rental market is similar in size and responsible from much energy consumption. Interestingly, the few studies that are addressing the rental market, find singificantly smaller price premiums than in the sales market. The findings add to this literature tradition and offer a comparative analysis of price premiums in the sales and rental market in Flanders. This allows us to not only show the similarities between both markets but also highlight the differences – creating valuable insights for academia, governments and real estate professionals.

This study examines how consumption values influence consumers' purchase intention of energy-efficient home appliances in South Africa, an emerging market. The study further investigates the mediating role of consumers' attention to energy-efficient labels affixed on home appliances while making a purchase decision and the moderating effect of consumer trust in the environmental claims.

Using a quantitative approach, this study relied on self-administered questionnaires to collect data from 505 household representatives in South Africa's Gauteng Province. The proposed conceptual model was empirically tested using structural equation modelling, moderation and mediation analyses.

The results revealed that economic, emotional and social values can only influence consumers' intention to purchase energy-efficient appliances if consumers pay attention to the energy-efficiency label affixed on the appliance. Functional value, however, has a significant direct impact on purchase intention. Moreover, the results indicate that trust in energy-efficiency labels strengthens the effect of functional and emotional values on consumers' attention to energy-efficiency labels.

Findings of this study highlight the importance of capturing the attention of consumers to energy-efficiency labels during the buying process as well as increasing their trust in those labels. Results indicate that consumers are more attracted to the functional and social values that energy-efficient appliances provide. This study is of particular interest to policymakers, retailers and manufacturers, as it sheds light on key strategies to implement to effectively promote the purchase of energy-efficient household appliances in South Africa.

The aim of this paper is to map and analyse the state of the art of eco‐energy labelling and its potential as a fundamental component in the transition process towards eco‐sustainability.

A detailed scenario of trends in eco‐energy labelling systems, both on an international and European Union scale are outlined, followed by identification and analysis of the key representative experiences. Subsequently, the main constraints that limit their full potential as a benchmark and tool of improved customer communication for environmental sustainability have been highlighted and critically analysed.

The full implementation of eco‐energy labelling, as a authentic driving force in sustainability building processes, requires the elimination of the critical factors identified. Therefore, standardisation of benchmarking methodologies, based on improved customer information mechanisms regarding qualitative and quantitative indicators, need to implemented. A strong commitment on the part of all participants involved, to define a multi‐level framework, capable of promoting a recognised international rating scheme in needed.

The most significant implications regard the attempt to classify and coordinate all the information concerning instruments, initiatives, policies and strategies related to eco‐sustainability.

The paper is a contribution towards pinpointing the current fragmented scenario of eco‐energy labelling tools with the aim of re‐conducting them into a coherent and more functional whole.

This research examines how the design of the online energy label can be improved to stimulate consumer choice of energy-efficient household products in Web stores. Based on general evaluability theory, the authors propose new label formats that aim to improve the evaluability of the label information for consumers and test their influence during two distinct stages in the online decision-making process: consideration set formation and final choice.

Two large-scale controlled online experiments are conducted with over 10,000 consumers in 10 European countries. The experiments test label alternatives in simulated online store environments, mimicking the two distinct decision stages, for four product categories to enhance generalizability. The data are analyzed using random-intercept linear and logistic regression models to account for their multi-level structure.

The results show that the impact of the online energy label on consumers’ online decision-making depends on both the label format and the decision stage (consideration vs choice), but in a different way than expected. The findings reveal that the current online energy label is significantly outperformed by a label that provides reference information by incorporating the scale range. This alternative label is particularly effective in the consideration set formation stage, and among consumers who consider energy efficiency a relatively unimportant choice criterion.

Online energy labels encourage consumers to consider and choose more energy-efficient products, especially if scale range information is included. The present results stress the importance of presenting this information early on in the online decision process. They also show that, particularly at this early stage and particularly for consumers who find energy efficiency a relatively unimportant choice criterion, label format matters.

The present findings provide important input for policymakers in the context of the ongoing revision of the EU energy label. They also help online retailers make decisions about when and how to present product information on their websites.

This study contributes to the literature on product labelling by examining the effects of relatively unexplored types of reference information in two distinct stages of the consumer decision-making process. To the best of the authors’ knowledge, this study is the first to test the effectiveness of the online energy label.

The purpose of this paper is to assess the impact of the Energy Performance Certificate (EPC) on the Italian real estate market, focusing on old buildings. The contribution of EPC labels to house prices and to market liquidity was measured to analyze different aspects of the selling process.

A traditional hedonic model was used to explain the variables of listing price, transaction price, time on the market and bargaining outcome. In addition to EPC labels, the building construction period and the main features of apartments were included in the model. A sample of 879 transactions of old properties in Turin in 2011-2014 was considered.

A first hedonic model let us suppose that low EPC labels (E, F and G) were priced in the market although EPC labels explained only 6-8 per cent of price variation. A second full hedonic model, which included apartment characteristics, revealed that EPC labels had no impact on prices.

In Italy EPC has been mandatory for house transactions since 2009, so there are few studies on the effect of EPC on the Italian real estate market at least to our knowledge. Furthermore, unusually for the Italian context, in this paper also transaction prices were analyzed, in addition to the more frequently used listing prices.

Earlier studies assume that historical dwellings and post-war dwellings in particular, are less sustainable than modern dwellings, justifying its demolition. Over time, historical buildings have been transformed and their energy performance improved. However, there is little known on the energy performance of historical dwellings. The purpose of this paper is to unveil the role of historical dwellings and its transformations in improving urban sustainability.

In this research, historical dwellings (built=1970) are distinguished in listed and unlisted dwellings. Three cities were selected as case study – Amsterdam, The Hague and Rotterdam – and three post-war neighborhoods – New-West, Mariahoeve and Ommoord. This research uses the difference in energy label (original vs current performance) to discuss the transformations of dwellings: comparing modern and historical; post-war and other historical; and listed and unlisted dwellings.

Findings reveal that historical and post-war dwellings have great potentials to raise the energy performance e.g. by applying after insulation and renewable energy sources. Furthermore, The Hague and its post-war neighborhood Mariahoeve have a considerably lower energy performance. Further research could relate the raising of energy performance to the cultural significance of such dwellings, to better discuss the role of attributes and their transformation to raising energy performance.

This paper addresses the knowledge gap of the current energy performance of historical dwellings, by presenting and discussing its role in improving urban sustainability.

The purpose of this study is to examine the importance of relationship marketing and particularly customer trust in energy-efficiency labels in social marketing interventions geared towards energy-efficient consumption.

A conceptual model was empirically tested on a sample of 517 users of electronic appliances living in South Africa. The study involved a cross-sectional design, and data were collected via a self-administered survey. Structural equation modelling and mediation analysis were used to test the hypothesised relationships.

The results indicated that customer trust is influenced by customers’ perception of the price and quality of energy-efficiency products, their attitude towards such products and their level of satisfaction with the environmental performance of the products. Customer trust, in turn, showed a positive influence on the customers’ intention to purchase energy-efficiency products and their loyalty to such products. As a central variable, customer trust was found to be an important mediator in the conceptual model.

The findings provide social marketers with important insights on the critical role that customer trust plays in achieving a long-term behavioural shift towards energy-efficient consumption.

Focusing on customer trust in energy-efficiency labels, this study provides empirical evidence of the mediating role of trust in influencing the intention to purchase and the decision to remain loyal to eco-friendly products. Moreover, this paper provides greater clarity on various levers to be activated to enhance the trust that customers have in energy-efficiency labels.

The purpose of this paper is to assess the relationship between nutrition knowledge and grocery store nutrition label use, with using nutrition information disclosure on menu selection in a group of hospitality management students, who shall be responsible for menu labelling in their future careers.

A between-subject design included 324 students, who were randomly assigned to choose from a menu labelled as follows: unlabelled; kcal label only; graphical label providing information on the per cent of the recommended daily intake of energy and four nutrients. Their nutrition knowledge and habit of reading grocery store nutrition labels were tested using an additional questionnaire.

The results showed that the provision of energy value information resulted in the selection of less energetic, less fat and less salted food, while a graphical label additionally led to the selection of food having a lower saturated fatty acid (SFA) and sugar content. Multiple regression analysis showed that the habit of packaged food nutrition label reading was a significant predictor of choosing food having a lower energy (p<0.001), fat (p<0.001), SFA (p<0.001), sugar (p<0.001) and salt (p=0.003) content, while the influence of nutrition knowledge on food selection was proven insignificant.

Given the established positive impact of menu labelling, these findings support the future European policy mandating energy and nutrient content disclosure on menus, but also point to the need for more-intense consumer education.

The purpose of this paper is to investigate whether energy-efficient green buildings tend to provide net lease structures over gross lease ones. It then considers whether owners benefit by trading away operational savings in a net lease structure.

Empirical models of office leasing transactions in Sydney, Australia, with wider transferability supported by analysis of office rent data in the USA.

Labeled green buildings are approximately four to five times more likely than non-labeled buildings to use a net lease structure. However, despite receiving operational savings, tenants in net leases pay higher total occupancy costs (TOC), benefiting owners. On average, the increase in TOC paid by tenants in a net lease is equal to or greater than savings attributed to an eco-labeled building.

A full accounting of TOC in eco-labeled buildings suggests that net lease structures provide numerous benefits to owners that offset the loss of trading away operational savings.

The principal-agent market inefficiency, or “split incentive,” is a widely cited barrier to private investment in energy-efficient building technology. Here, a uniquely broad look at rental cash flows suggests its role as a barrier is exaggerated.
