Daylighting Performance of Solar Control Films for Hospital Buildings in a Mediterranean Climate

One of the main retrofitting strategies in warm climates is the reduction of the effects of solar radiation. Cooling loads, and in turn, cooling consumption, can be reduced through the implementation of reflective materials such as solar control films. However, these devices may also negatively affect daylight illuminance conditions and the electric consumption of artificial lighting systems. In a hospital building, it is crucial to meet daylighting requirements as well as indoor illuminance levels and visibility from the inside, as these have a significant impact on health outcomes. The aim of this paper is to evaluate the influence on natural illuminance conditions of a solar control film installed on the windows of a public hospital building in a Mediterranean climate. To this end, a hospital room, with and without solar film, was monitored for a whole year. A descriptive statistical analysis was conducted on the use of artificial lighting, illuminance levels and rolling shutter aperture levels, as well as an analysis of natural illuminance and electric consumption of the artificial lighting system. The addition of a solar control film to the external surface of the window, in combination with the user-controlled rolling shutter aperture levels, has reduced the electric consumption of the artificial lighting system by 12.2%. Likewise, the solar control film has increased the percentage of annual hours with natural illuminance levels by 100–300 lux

A survey of real-time crowd rendering

In this survey we review, classify and compare existing approaches for real-time crowd rendering. We first overview character animation techniques, as they are highly tied to crowd rendering performance, and then we analyze the state of the art in crowd rendering. We discuss different representations for level-of-detail (LoD) rendering of animated characters, including polygon-based, point-based, and image-based techniques, and review different criteria for runtime LoD selection. Besides LoD approaches, we review classic acceleration schemes, such as frustum culling and occlusion culling, and describe how they can be adapted to handle crowds of animated characters. We also discuss specific acceleration techniques for crowd rendering, such as primitive pseudo-instancing, palette skinning, and dynamic key-pose caching, which benefit from current graphics hardware. We also address other factors affecting performance and realism of crowds such as lighting, shadowing, clothing and variability. Finally we provide an exhaustive comparison of the most relevant approaches in the field.Peer ReviewedPostprint (author's final draft

Store Atmosphere Strategies and their Effects on Purchase Intention

Retailers must continually adjust to the realities due to the fast speed of today's society, which brings with it constant changes in fashion trends, technology advancements, and also the modification of lifestyle. Even though such improvements and adjustments are unnecessary, they must be made in order to keep the store attractive or to modernize the technical infrastructure and lower operating energy usage in the face of competition from new, similarly minded businesses. The functioning of the retail operation is heavily influenced by the architectural and design solution, where the customer must first arrive at the store, which then needs to draw them in and persuade them to make a purchase. Recent years have seen a rise in the importance of the shopping environment. Many stores rely on the fact that they have the most comfortable atmosphere, which forces the customer to stay in the store as long as possible. Sellers also try to make shopping an experience, making it necessary for the customer to feel satisfied in the store. Shopping atmosphere and control can help higher customer satisfaction. It is therefore very important to monitor the key factors that affect the atmosphere in the store. This article examines selected elements of the shopping atmosphere and its impact on consumers in electronic markets operating in Turkey, Germany, and England. It integrates research, survey, and observation into real terms of selected retail operations. Based on the findings, the conclusion on adapting selected factors influencing the atmosphere is proposed to improve the overall well-being of customers and thus their satisfaction during shopping

Case study on economic return on investments for safety and emergency lighting in road tunnels

While planning a double-hole road tunnel with a length higher than one km, it is important to pay attention to the safety factor if an accident occurs. If there is a power outage, in order to avoid critical situations that could jeopardize the safety of the people present (facilitating the stream coming out from the tunnel and the arrival of the emergency personnel), it is really important to guarantee uninterrupted lighting of roadways, mandatory emergency lay-bys, and ways of escape. Uninterrupted service of the lighting systems supply must be guaranteed, in accordance with the current regulations, through the exertion of UPS (Uninterruptible Power Supply) and power units. During tunnel construction, such devices represent a cost that must be amortized. In this case study, which takes into consideration a section of a road tunnel characterized by emergency lay-bys and ways of escape, emergency and security lighting were planned and installation and management costs were evaluated. The goal of this research was the creation of a cash flow thanks to the energy generated by photovoltaic panels, in a way that the service life of the system (25 years) coincided with the amortization of the costs of the backup electrical equipment installation (complying with the regulations). The possibility of over-dimensioning the UPS and providing it with a proper photovoltaic panel surface (235 kWp) to generate and exchange electric energy with the grid was taken into consideration

Nature and Functioning of Visual Merchandising in Organized Food Retailing

The Indian food retail sector is one of the biggest industries in the country with an annual turnover of around US $18 billion. It has been estimated that organized food retailing in India which is worth US$ 666 million today will increase to US $ 33,333 million by 2015. The inherent attractiveness of the segment is luring more and more investors from both India and abroad, as is clearly indicated by the opening of a number of retail stores by major corporate houses like those of Bharti, Reliance, Pantaloons (Food Bazaar), Subhiksha, ITC (Choupal fresh), etc. However, to build long-term customer loyalty, price, quality, variety, and right image are very much needed. To attain this, the aesthetic appeal of the store and the way the products are displayed at the store are very important. Thus, the visual merchandising (VM) is the need of the hour at the food retail stores. This paper has studied various components of VM at retail stores and has analyzed the impact of indoor signages on customer’s buying behaviour. A comparative analysis of VM has been done at Food Bazaar (Ambala), Subhiksha (Chandigarh) and ITC Choupal Fresh (Chandigarh). Problems faced in implementation of VM at retail stores have been highlighted and some implications have been mentioned.Agribusiness,

High quality indoor environments for sustainable office buildings

The quality of office indoor environments is considered to consist of those factors that impact occupants according to their health and well-being and (by consequence) their productivity. Indoor Environment Quality (IEQ) can be characterized by four indicators: • Indoor air quality indicators • Thermal comfort indicators • Lighting indicators • Noise indicators. Within each indicator, there are specific metrics that can be utilized in determining an acceptable quality of an indoor environment based on existing knowledge and best practice. Examples of these metrics are: indoor air levels of pollutants or odorants; operative temperature and its control; radiant asymmetry; task lighting; glare; ambient noise. The way in which these metrics impact occupants is not fully understood, especially when multiple metrics may interact in their impacts. While the potential cost of lost productivity from poor IEQ has been estimated to exceed building operation costs, the level of impact and the relative significance of the above four indicators are largely unknown. However, they are key factors in the sustainable operation or refurbishment of office buildings. This paper presents a methodology for assessing indoor environment quality (IEQ) in office buildings, and indicators with related metrics for high performance and occupant comfort. These are intended for integration into the specification of sustainable office buildings as key factors to ensure a high degree of occupant habitability, without this being impaired by other sustainability factors. The assessment methodology was applied in a case study on IEQ in Australia’s first ‘six star’ sustainable office building, Council House 2 (CH2), located in the centre of Melbourne. The CH2 building was designed and built with specific focus on sustainability and the provision of a high quality indoor environment for occupants. Actual IEQ performance was assessed in this study by field assessment after construction and occupancy. For comparison, the methodology was applied to a 30 year old conventional building adjacent to CH2 which housed the same or similar occupants and activities. The impact of IEQ on occupant productivity will be reported in a separate future pape
