Abstract

Purpose

Energy-efficient retrofitting of existing buildings is an inexpensive way of reducing energy consumption and mitigating climate change impacts. The purpose of this study is to examine electricity savings and carbon dioxide (CO2) emission reduction potentials of energy-efficient retrofit measures for surveyed two large shopping malls in India.

Design/methodology/approach

A techno-economic model was developed to estimate the electricity savings achieved due to energy-efficient retrofit measures in shopping malls that were surveyed in 2017. Alternative scenarios were constructed based on capital cost and cost of conserved energy (CCE) value for retrofit measures: cheapest replacement, best available technology and best value for money. The life-cycle electricity and CO2 emission savings and payback period for end-use retrofit measures were evaluated.

Findings

The estimated average electricity savings were around 39–56% for various retrofit measures across all three scenarios while the average CO2 emission reductions were around 50–125 kt-CO2. Retrofits to light-emitting diode lights and air conditioners with inverter technology offered more life-cycle electricity savings. Paybacks for most lighting end-use measures were estimated to be within 1.5 years while for most space conditioning end-use measures were between 1 and 4 years.

Originality/value

The primary survey-based comprehensive research makes an exclusive contribution by estimating life-cycle electricity savings and CO2 emission reductions for energy-efficient retrofit measures of lighting and space cooling end-use appliances for existing shopping malls. The present research methodology can also be deployed in other types of commercial buildings and in residential buildings to estimate electricity savings from energy-efficient retrofit measures.

Abstract

Purpose

Saving energy is an essential issue in the world to attenuate climate change. To achieve the goal, energy-saving appliances such as refrigerators should be promoted. This study aims to analyze the conditions enabling Japanese households to purchase such appliances, focusing on the relation with preferences for renewable energy as one of the non-monetary incentives.

Design/methodology/approach

A conjoint analysis is used. A random parameter logit model and nested logit model are used for estimation. Data were collected through an online questionnaire of the Rakuten Insight service.

Findings

Households will purchase energy-saving appliances when renewable energy is used for electricity generation. This implies that households will purchase energy-saving appliances with electric power generators by renewable energy such as solar panels and home micro-wind generators.

Research limitations/implications

The response rate and attributes of respondents and non-respondents are not shown to researchers in the web-questionnaire service.

Social implications

Promoting energy-saving appliances and renewable energy is essential in Japan (as in other countries) to save energy and to attenuate climate change. Based on the results, both energy-saving appliances and renewable energy will be widely used.

Originality/value

Although many studies have analyzed households’ preferences for energy-saving appliances and the effects of non-monetary incentives, studies that mentioned the relation with preferences for renewable energy are few. This study analyzes the relation and proposes policy recommendations to promote both energy-saving appliances and renewable energy.

The purpose of this study is to develop a theoretical framework of consumers’ purchase intention of energy efficient home appliances.

Abstract

Purpose

The purpose of this study is to develop a theoretical framework of consumers’ purchase intention of energy efficient home appliances.

Design/methodology/approach

Non-probability quota based on age and education and purposive sampling technique have been used to assess data collected by a questionnaire survey.

Findings

The findings of the study reveal that consumers’ knowledge of eco-labels, environmental concern and perceived consumer effectiveness are the important predictors of purchase intention. However, the positive relationship between green trust and products’ functional value was found insignificant. It is believed that consumers’ are skeptical about products’ functional benefits.

Research limitations/implications

Although this study has presented a holistic approach to assess consumer purchase intention for energy-efficient home appliances, there are some limitations of the current study. First, this study has focused on consumer intention to purchase energy-efficient home appliances rather than actual purchase of appliances. Ajzen (1991) argued that intention is the accurate and immediate measure of actual, but gaps exist between intention and the actual behavior of the consumers (Ajzen and Fishbein, 1980). Consumers’ intentions may not always result in actual behavior. Thus, to expand research applicability, researchers should include actual behavior of consumers by conducting interviews or collecting data from the same consumers after an interval of three to six months. Second, the study has focused on consumers’ psychographic variables, there may be many other factors such as technological variables, government and pressure group influence and media impact on consumer intention to purchase energy-efficient home appliances. Future studies can integrate the impact of these potential variables on consumer purchase intention of energy-efficient home appliances with the same model. The third limitation is related to the methodology of this study, the quantitative method has been used in this study. Future studies may use qualitative and mixed methods to better understand consumers’ inclination of purchase intention of energy-efficient home appliances in Pakistan. Besides, a qualitative study will be helpful to explore new variables that are essential in the decision-making of consumers for the purchase of energy-efficient home appliances in Pakistan. Pakistan is a developing country where the majority of the people are belonging to the middle-class; there may be many other important factors that affect consumers’ purchase intention of energy-efficient home appliances. Therefore, an in-depth qualitative study would be helpful to explore those variables in the context of a developing country.

Practical implications

Energy consumption has posed serious threats to the sustainability of the environment and endangered the lives of many species across the globe. Environmental degradation due to unsustainable consumptions has provided ample opportunities to the marketers that led to the development of sustainable products such as energy-efficient home appliances. In this study, the antecedent of purchase intention of energy-efficient appliances includes attitude, functional values, perceived consumer effectiveness, consumers’ knowledge of eco-labels, environmental concern and green trust. Although researchers have extended TBP to predict consumers’ purchase intention of energy-efficient appliances, studies lack to provide a holistic view from consumers’ perspective. Consumers’ concern for the safety of the environment depicts consumers tendency to purchase environmentally friendly products and promote less hazardous products. Marketers should incorporate environmentally friendly benefits to the product that serve to attract maximum consumers and maintain harmony with the environment. Consumers’ knowledge of eco-labels, green trust and functional values are a vital construct that needs focus in term of the energy-efficient appliances purchase decision. Eco-labels are one of the emerging marketing tools that serve to guide consumers related to products environmentally friendly attributes and contribute to the acceptability of products. Marketers can use eco-labels to differentiate green products from conventional and establishes consumers’ trust in product performance.

Originality/value

This study is relevant to energy-efficient home appliances. Systematic literature of previous studies suggested the need to conduct and examine the antecedents of energy-efficient home appliances in developing markets. This research highlights that perceived consumer effectiveness is the most influencing factor affecting intention. The implications of this study would be helpful in understanding consumers’ behavior toward the purchase of green products in developing markets.

Abstract

Purpose

The purpose of this paper is to identify the barriers to consumers’ intention to purchase energy efficient appliances. It uses multiple regression analysis to predict the factors that deter consumers’ purchase intention.

Design/methodology/approach

Five barriers to consumers’ intention to purchase energy efficient appliances were identified through an exhaustive literature survey. Data were gathered from 300 respondents from Pune city from the state of Maharashtra in India through a survey. The items were measured on a five-point Likert scale. Validity and reliability of the scale were established. Multiple regression analysis was conducted to predict consumers’ intention to purchase energy efficient appliances based on factors identified.

Findings

Findings revealed that some degree of uncertainty was associated with energy efficient appliance purchase. In addition to possessing lower degrees of awareness on energy efficient appliances, consumers tend to disbelieve claims made on labels of energy efficient appliances. Consumers also feel inconvenience in identifying these appliances, spending time to know about them and paying the price to purchase them. Hence, the factors – scepticism towards label claims and perceived personal inconvenience – were found to have negative impact on consumers’ purchase intention. Societal norm was found to have a positive impact on consumers’ purchase intention. Interestingly, price sensitivity and perceived product risk (which were expected to have a negative relationship with consumers’ purchase intention) displayed a positive relationship.

Research limitations/implications

The model proposed here is based on the researcher’s identification of the barriers. There might have been unidentified barriers that were not considered. The research does not account for manufacturing or policy-based issues that might also pose as barriers. The study encourages marketers to re-examine marketing and communication policies associated with the sale of energy efficient appliances.

Originality/value

The paper provides insights into the external barriers faced by consumers while purchasing an energy efficient appliance. This research enables managers to understand consumer’s preference for conventional products over energy efficient ones. It attempts to check the presence of barriers to energy efficient appliances, identified from literature in a tier 1 city of India. Tier 1 city is the city with population greater than 1,00,000 as per 2001 census of India.

Abstract

Purpose

Power management in households has become the periodic issue for electric suppliers and household occupants. The number of electronic appliances is increasing day by day in every home with upcoming technology. So, it is becoming difficult for the energy suppliers to predict the power consumption for households at the appliance level. Power consumption in households depends on various factors such as building types, demographics, weather conditions and behavioral aspect. An uncertainty related to the usage of appliances in homes makes the prediction of power difficult. Hence, there is a need to study the usage patterns of the households appliances for predicting the power effectively.

Design/methodology/approach

Principal component analysis was performed for dimensionality reduction and for finding the hidden patterns to provide data in clusters. Then, these clusters were further being integrated with climate variables such as temperature, visibility and humidity. Finally, power has been predicted according to climate using regression-based machine learning models.

Findings

Power prediction was done based on different climatic conditions for electronic appliances in the residential sector. Different machine learning algorithms were implemented, and the result was compared with the existing work.

Social implications

This will benefit the society as a whole as it will help to reduce the power consumption and the electricity bills of the house. It will also be helpful in the reduction of the greenhouse gas emission.

Originality/value

The proposed work has been compared with the existing work to validate the current work. The work will be useful to energy suppliers as it will help them to predict the next day power supply to the households. It will be useful for the occupants of the households to complete their daily activities without any hindrance.

To determine the probable drainage load for sizing a stack serving a number of domestic washrooms in high‐rise buildings, with various occupant loads served by an appliance

Abstract

Purpose

To determine the probable drainage load for sizing a stack serving a number of domestic washrooms in high‐rise buildings, with various occupant loads served by an appliance and simultaneous use of appliances in a domestic washroom taken into account.

Design/methodology/approach

With the reported probable demand patterns of domestic appliances from laboratory testing results, on‐site measurements and survey studies, the probable maximum discharge flow rates from a number of domestic washrooms in a stack are estimated with Monte‐Carlo simulations.

Findings

The results demonstrated that the occupant loads and the usage patterns of an appliance had significant effects on the sizing of a drainage stack. It was reported that a reduction of 16 per cent in the design discharge flow rate for a washroom, at an occupant load of 4.2 persons per apartment, could be achieved with no more than one appliance discharging at a time. Influence of the occupant load served by an appliance on the probable maximum drainage demand at the stack was addressed. The results also showed a reduction of the predicted discharge flow rate at the stack serving a number of typical domestic washrooms from −26 to +21 per cent as compared with those predicted by the nominal occupant load in current practice.

Research limitations/implications

The model parameters were determined from surveys for some high‐rise residential buildings in Hong Kong and from some laboratory testing results for typical domestic sanitary appliances. The model therefore may require adaptation for use in other countries.

Practical implications

A useful source of information in determining the stack size serving a number of domestic washrooms for those involved in building design and management related to drainage systems of residential buildings.

Originality/value

This paper proposes mathematical expressions in sizing a drainage stack serving a number of domestic washrooms in high‐rise buildings, where drainage demands are dependent on the building occupant loads at certain discharge patterns of appliances in a domestic washroom.

Abstract

Purpose

This paper aims to explore how home economists, employed by the Good Housekeeping Institute, may have influenced the use of principles from the home economics movement in advertising appeals for electric appliances.

Design/methodology/approach

A content analysis of more than 400 print advertisements from Good Housekeeping magazine, from 1916 to 1929, was conducted to determine whether manufacturers used appeals derived from the home economics movement in their advertising. Then, the Good Housekeeping Institute’s history is explored to suggest how its relationship with manufacturers may have resulted in the use of the home economics movement’s principles in advertising appeals for electric appliances.

Findings

The content analysis shows that principles of the home economics movement appeared in advertising appeals for electric appliances in advertisements placed in Good Housekeeping magazine during the period studied. Through its unique relationships with electric appliance manufacturers, the Good Housekeeping Institute seems to have taught manufacturers how to position electric appliances by incorporating the principles of the home economics movement in their advertising appeals.

Practical implications

This research demonstrates how a commercial organization successfully navigated its relationships with manufacturers and consumers for mutual benefit.

Originality/value

This work is the first to link the Good Housekeeping Institute’s work with manufacturers to its influence on advertising appeals. This work also expands understanding of the influence of women on marketing practice. Existing literature on women’s publications is also broadened by analyzing Good Housekeeping, rather than the more frequently studied Ladies’ Home Journal.

Abstract

Purpose

The purpose of this study is to predict the antecedents of consumers' purchase intention of energy-efficient home appliances. This study incorporated two additional constructs (knowledge of eco-labels and knowledge of eco-labels) in the model of the theory of planned behavior. Consumers' enhanced trust for energy-efficient products is crucial to purchase intention. The second construct is consumers' knowledge of eco-labels. Knowledge of eco-labels would help to assess consumers' tendency toward environmental problems and intention to purchase energy-efficient home appliances.

Design/methodology/approach

This study used a quantitative approach using a survey (questionnaire) method to collect data of respondents. Non-probability quota based on age and convenience sampling techniques were employed to select the participants of this study.

Findings

The findings of the study revealed that consumer knowledge of eco-labels, green trust, subjective norm, attitude and perceived behavioral control have positive influence on purchase intention of energy-efficient home appliances.

Originality/value

Eco-labels are served as a marketing tool to distinguish producer's products from others. Prior studies have only focused on consumers' general knowledge. This study helps marketers to understand and design strategies to generate more value for green consumers. This study also contributes to the literature on green marketing by employing the theory of planned behavior.
