title: Optimized Automatic Lighting Control in a Hotel Building for Energy Efficiency
abstract: Energy efficient buildings are demand of today's world and very important area for R&D, because requirement of electricity is quite higher than available resources. Energy Efficiency in buildings is a very popular area for R&D. This paper demonstrates through software simulation that a significant reduction in the energy consumption can be achieved using daylight based lighting control. Lighting in a building is one of the dominant sources for electric energy consumption and because of it a needs special attention during energy optimization, its heating effect also affects HVAC loading in building. Automatic lighting control can be daylight level, occupancy or schedule. Day light level based strategies takes efficient consideration of natural daylight availability and operate only the minimum amount of electrical lighting just to fulfill the desired level of lighting. The two main methods for controlling lighting in day lighted areas are switching daylight and dimming daylight. Gradual lighting control can provide 30 40% energy saving. The saving can be even more with on/off type of light control.

title: Hotel Lighting Systems in the Context of Global Energy Crisis An Approach in Perspective of Sustainable Development
abstract: The first concerns regarding the hotelier design occurred since the early twentieth century. Under the pressure of contemporary social and economic factors and under constraints within different categories, designers with a broad vision and who are able to work in an integrated system facing the constraints of legal, environmental and safety regulations imposed by European Union are in high demand. This paper aims to highlight through scientific approach that only an integrated hotelier design system can provide a unified vision in Europe regarding the creation of unitary standards, but with high specificity to enhance competitiveness.

title: Hotel lighting load influence on marine cast resin distribution transformer aging rate
abstract: Nowadays, energy efficiency and its various aspects are quite important than before in marine application. Also in modern cruise ships, energy consumption of hotel load is as crucial as propulsion load and should be permanently provided without even short term interruption. This study has concentrated on hotel lighting load and its harmonic contents influence on marine cast resin transformer in ship electric system. Advantages and disadvantages of conventional and recent developed lighting systems are debated. Harmonic contents of incandescent, fluorescent, Compact Fluorescent (CF) and Light Emitted Diode (LED) lamps are measured and discussed. THD level of each and every lamp is also calculated. The influence of non linear load on hot spot temperature rise of cast resin transformer is discussed. Finally, distribution cast resin transformer de rating and its aging rate under non sinusoidal condition initiated by lighting load is simulated and influence of each load on transformer is discussed.

title: A study on energy consumption of hotel buildings in Vietnam
abstract: This paper aims to determine energy use intensity (EUI) and the percentage of end use energy consumption in hotel buildings in major cities of Vietnam, including Hanoi, Da Nang and Ho Chi Minh City (HCMC) Data from 32 hotels were gathered from the website on energy efficiency promotion of Ministry of Construction. The average EUI in the whole country was 151 kWh/m2.year, and the figures for Hanoi, Da Nang, and HCMC were 184; 71 and 212 kWh/m2.year, respectively. At the same time, the structure of end use energy consumption was estimated, of which 54% for heating, ventilation and air conditioning (HVAC) 10% for lighting, 19% for plug equipment and 17% for lifts.

title: Application of equivalent occupation method as a tool for energy management in hotel sector
abstract: At nowadays, the operational control of energy performance indicators based on the equivalent occupation method plays a fundamental role in the rational use of energy for the hotel sector, since it allows in a competitive way to comply with the quality of the service offered by the company in terms of the thermal comfort of the occupants, minimizing the environmental impact. Within the framework of the energy diagnosis and implementation of the program of efficient energy management under ISO 50001: 2011, based on the method of equivalent occupation for a hotel company on the Colombian Caribbean coast, the line base, target line by 2015, determining performance control indicators such as accumulative trend and base efficiency index 100, to identify potential savings. From the diagnosis, 9.11% of energy savings were obtained by operational control. Through the implementation of corrective action plans, such as the shutdown of unnecessary equipment in the company, installation of LED lighting modules, the configuration of thermostats, in addition to training and sensitization to staff, and reactive energy control in the hotel effective savings were achieved around 8% of primary energy consumption by 2016.

title: Lighting Energy Savings Opportunities in Hotel Guestrooms
abstract: A study was conducted by LBNL/DOE in order to better understand the lighting usage and energy consumption patterns in typical hotel guestrooms. This involved a multiphase research, development, and demonstration program. This program started with the identification and characterization of common lighting technologies in hotel guestrooms and ended in the measurement and monitoring of existing and newly developed technologies at a hotel test site. Emphasis was placed on determining where lighting energy was being used by guests and identifying the savings potentials that energy efficient technologies could present. Data from this study indicates that compact fluorescent lamps (CFLs) and occupancy sensors offer significant energy savings potential in hotel guestrooms.

title: Energy Performance of Hotel Buildings in Lijiang, China
abstract: The hotel industry in China has experienced rapid growth in the past ten years and made a considerable contribution to the global tourism economy. This paper focuses on the energy performance of hotel buildings in Lijiang, China. Hotel characteristics, daily operational data, and energy use data were collected by carrying out a survey of 24 hotels. The average annual energy use intensity (EUI) of four three two and one star rated hotels was 180.8 kWh/m 2 113.3 kWh/m 2 74.2 kWh/m 2 and 70.2 kWh/m 2 respectively. Electricity, as the dominant energy source, accounted for 81% of total energy consumption and was used in the operation of air conditioning, lighting, heating, etc. Pearson correlations between EUI showed that hotel star rating, number of guest rooms, room revenue, and number of workers gave a reasonably strong correlation. A regression based benchmarking model was established to predict EUI, and a standardization process of EUI was illustrated by statistical analysis.

title: Energy saving potential through Energy Conservation Building Code and advance energy efficiency measures in hotel buildings of Jaipur City, India
abstract: Commercial buildings of conventional practices consume significant energy, especially hotel buildings. Therefore, the study aims to estimate energy saving potential in three categories of hotels from Jaipur city, India. Energy Conservation Building Code (ECBC) and advance Energy Efficiency Measures (EEMs) beyond ECBC specifications were implemented such as building envelope, Heating, Ventilation and Air Conditioning (HVAC) system and lighting system for estimating energy saving potential. Dynamic thermal simulation tool was used for modeling and simulation of existing hotel buildings and simulation models were calibrated against actual energy consumption of study hotels. Implementation of ECBC to hotel Category 1, Category 2 and Category 3 demonstrates energy savings of 37.2% 18.42% and 25.82% respectively with payback period of 2.39 6.41 years whereas application of advance EEMs in respective hotels led to increase in energy savings up to 61.75% 53.92% and 54.61% in respective hotel category with payback period of 4.22 5.11 years. Implementation of ECBC code to existing hotel buildings in Jaipur city can save 27.9 GW h/year and with the use of advance EEMs, the city can save 67.04 GW h/year of energy. This study concludes that there is significant energy saving potential in hotel buildings in India through implementation of ECBC and other energy efficiency measures.
