Abstract [en]

This paper describes the framework for a proposed certification for energy consultants targeting the grocery sector, i.e. supermarkets. Thecertificationshould cover necessary knowledge and requirements, with the overall aim of increasing energy efficiency and reducing related costs for the store at the system level. Within the retail sector, supermarkets are the most energy-intensive buildings. Buildings intended for food sector applications need to be of a special design, with requirements that differ from other premises. Half of the electricity used is employed to keep food cold. However, energy efficiency can be improved through efficient equipment and increased knowledge, sometimes by 30-50% or more. This paper presents different skills and requirements needed by a certified energy consultant, CEC, working with energy efficiency in supermarket, from the retailer's perspective. Thus, the specifications can be used to further develop the certification area; energy consulting for supermarkets and good practice approaches targeting this area.

Abstract [en]

In the retail grocery business, new competitors such as pure e-commerce players are growing fast, and, in order to compete, ‘brick and mortar’ stores such as supermarkets need to become more professional at providing excellent customer service, and to use the physical servicescape as the main competitive advantages. However, supermarkets also face a challenge to offer consumers high quality products while at the same time providing a pleasant and functional servicescape. Products like groceries often need to be stored in cabinets due to strict regulations and in order to maintain correct temperatures. Some of these cabinets have doors which make them more energy-efficient (Evans et al., 2007 ;  Faramarzi et al., 2002), reduces costs, and contributes to grocery quality, but it can also affect the perceived servicescape, and risk a negative impact on sales (Waide, 2014; Kauffeld, 2015). For example, moisture from the atmosphere that condenses on the inside of the door glass (Fricke and Bansal, 2015) may make the cabinets less transparent, and doors can obstruct consumers from passing by. Thus, having chilled groceries in cabinets with doors can be both beneficial and problematic. However, no studies have been conducted on how open (no doors) or closed (with doors) cabinets for chilled groceries impact consumer perception and behavior. Hence, the purpose of the study is to contribute to an understanding of how consumers behave and what they perceive when shopping chilled groceries from cabinets with doors and without doors in the supermarket.

Based on a qualitative research approach, combining in-store observations and focus group interviews, and focusing on Bitner's (1992) three environmental variables in the servicescape, i.e. (1) ambient condition, (2) space and functions, and (3) signs, symbols and artifacts, the study investigates the question: do open or closed cabinets for chilled groceries in the supermarket impact consumer perception and behavior, and if so, how?

Our results indicate that consumers’ behavior and perceptions of the foodscape differ when there are doors or no doors on the cabinets. The paper thereby contributes to servicescape research by focusing on a particular part of supermarkets – the foodscape for chilled groceries–and by enhancing the understanding of environmental variables in the servicescape. The results further show how doors lead to different forms of approach or avoidance behavior in terms of accessibility and that consumers’ vision, olfaction and tactility all influence consumers’ perceptions of freshness and cleanliness in relation to doors or no doors. Our results also have practical implications for retailers who are designing new stores or considering changes in existing store layouts.

Abstract [en]

In this study we aim to shed light on waste heat from commercial refrigeration, which is common but unnecessary. Excess heat is the heat which is not recovered, although it is possible to do so. We include heating for existing buildings: grocery stores as stand-alone, or within another building. VariousSwedish perspectives of the parties involved, tenant and landlord, are discussed. Theoretically and technically, it is not difficult to distributeexcess energy from a tenant to another receiver, which in turn uses the energy. However, to meet energy goals regarding energy consumption for heating buildings requires new and efficient approaches. The technique is already known and availableon the market. We suggest that availableenergy and heat recovery projects, contracts and agreements maysignificantly enhance the possibility of creating viable energy efficiency projects, and include excess heat. Results include lessons learned from the parties.

Abstract [en]

In this study, a completely new type of air-to-liquid heat exchanger, adapted for obtaining good heat transfer performance even at a laminar flow regime on the liquid side has been evaluated in a display cabinet application. The heat exchanger consists of parallel plates, with liquid in every second passage and air in the other passages. Tests were performed with a traditional open vertical display cabinet, first with a traditional finned-tube coil and thereafter with the new type of heat exchanger, both in a climate chamber and thereafter in the field. The results from both tests showed that the liquid inlet temperature could be increased by around 6°C, from the range -8°C - -7°C with the traditional coil to the range -2°C -1°C with the new type of heat exchanger, which can lead to considerable energy savings and operation without the need for defrosting of the heat exchanger.

Abstract [en]

In the supermarket environment three factors must be considered: food (food quality), personnel (working conditions), and customers.The customers do not remain in this environment very long but are of particular interest since they constitute the supermarket’s commercial basis. However, there are no recommendations on the indoor environment based on this category. This study compares the perceived indoor thermal environment with simultaneous objective measurements of the thermal environment and includes multiple enquiry methods. These methods have been used for this specific environment in order to understand how customers perceive, evaluate, and prefer variations in the thermal environment.

Measurements were performed in summer and winter in front of twelve display cabinets, over 1100 questionnaires have been received.To provide recommendations, this study presents measured and perceived comfort in supermarkets, information which can be used for prescribing suitable thermal environments for customers.

Abstract [en]

”Active Ageing – Personalised food and meal solutions for health and quality of life”(Aktivt åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hosäldre. Diarienr 2013-02780) is a project that aims to maintain the quality of life and autonomy of older persons, through individual and personalised meal solutions that fit their needs and requirements. The target group are primarily the age 75 or older. Five work packages are included in the project. One of the work packages had the scope of developing a concept for the ordering, distribution and delivery of meal to the elderly.The final report from that work package can be found in SP Report 2015:75. An interdisciplinary approach – combining knowledge of ICT (information and communications technology) – Technology, food quality, packaging, logistic, sensory, and waste/return systems for the food that is distributed is increasingly necessary. Being able to influence food choices, for the elderly, is central and open up possibilities for different activities and the development of new products, models and services that might be facilitated by collaborating with SMEs (micro, small and medium sized enterprises) and other business partners interested in delivering solutions for the elderly consumers. The concept for the ordering, distribution and delivery of meal to the elderly developed in the project can be used by other end users and/or for other products and services.Students at the KTH performed a case study “cold chain of chilled meals” together with participant, Medirest, from the project Active Ageing which is presented in this report.The focus is on hospital food provisioning, which is an even more delicate branch in the general food processing panorama. The entire cold chain is mapped and analysed, from the factory up to the hospital wards, in order to ensure integrity and identify critical points. The work is done in collaboration with Medirest, a company responsible for food provision in five hospitals in Stockholm’s county. The aim of the project were to investigate if Medirest cold chain of a meal containing chicken were kept intact starting from when the frozen chicken were thawed until it was delivered in a meal box to the S:t Görans Hospital, including all storing and transportation.Starting from the background knowledge of food regulations, production procedures, logistic technologies and delivery schemes, the overall situation can be depicted and subsequently investigated. Temperature measurements were carried out upon cooked chicken. The results shows that the chicken holds a temperature below 6°C, which is Medirest’s goal, when it is put in the holding fridge at Medirest. The temperature fluctuates a lot.When it is put in the holding fridge at the hospital the temperature is held more constant, just above 6°C. The difference may depend on the activity and the amount of internal loads, as well as the ventilation flow required at the Medirest facility. The most exposed parts of the cold chain were during the preparation of the meal boxes, the transportation to the hospital, and during the delivery of the meal boxes to the different wards. The measurements were carried out in November, which is a relative cold month. Problems not showed in this study could however occur during the summer months when the cold chain is exposed to higher loads and higher ambient temperatures.

Abstract [en]

In Europe the percentage of citizens aged 65 and over is increasing at an unprecedented rate, and is expected to account for over 30% of the population by 2050. Coupled with an increase in life expectancy, this massive demographic change calls for a major effort to ensure quality of life in our older population. A thorough understanding of the elderly as food consumers, their nutritional needs, their food perception and preferences is increasingly needed. The role of food in healthy aging was a prominent theme at the 6th European Conference on Sensory and Consumer Research, which had quality of life across the life span as a focal point. This short paper is based on a workshop held at the EuroSense meeting, focusing on research from sensory and consumer scientists. The workshop featured contributions focusing on food-related perception, needs and behavior of the elderly, and aimed at demonstrating the relevance of sensory and consumer scientists in promoting food-related well-being in an aging population. The workshop contributions are here reviewed and summarized three main themes: nutritional needs, food perception and aging, and behavioral drivers of food consumption.

Abstract [en]

In a supermarket setting, customers likely feel the chilled air from refrigerated units displaying their contents to passing customers. Supermarkets, by their nature, contain a diverse range of perishable goods stored in different designed units within one large building, whose distinct storage temperatures result in the unusual thermal environment that customers encounter when shopping. Unfortunately, this open environment results in huge amounts of wasted cold air from display units, the reduction of thermal comfort for customers, and a reduction in the quality of the food. A possible solution to improve comfort for customers, reduce cold air waste, help preserve foods, and save money for retailers includes innovative doors for open display cabinets. Such doors will save money for the retailer by lowering the costs for energy in supermarkets. Doors should, therefore, be viewed as an option and solution for not only the merchandiser, but also for the customer.
