Green Hotel

With the concept of green hotel, the hotel industry has started to consider a sustainable design and operation to obtain more competitiveness. It is needed to implement a convenient way to recognize a real-time situation about the indoor environmental quality (e.g., temperature, relative humidity, CO2, TVOCs, PM2.5, etc.) and the relevant energy efficiency in a hotel guestroom. This study aimed to develop a scalable integrated platform for providing real-time monitoring, alert notification, and analytics so as to satisfy the level of the occupants’ comfort and satisfaction. Facility managers could gain insight from the real-time hierarchical and historical information and take actions at a point of time. The novel approach could create a comfortable and healthy environment for the occupants in a hotel guestroom while realizing the energy efficiency in real time. The proposed platform was validated with three guestrooms in a hotel, and the scalability of the system was fully confirmed. In the future studies, it is expected to deploy the proposed platform to a larger physical entity of the hotel, providing flexibility and expandability in accordance with the strategic facility planning of the hotel. Furthermore, it is planned to develop various kinds of occupant-centered services in a hotel guestroom level.

Working Efficiency

Comprehensively monitoring indoor environmental quality (IEQ) parameters and their dynamic relations is essential to ensure improved productivity and a healthy environment for building occupants. Although IEQ significantly influences working efficiency, studies addressing this aspect with researchers in institutes as the focal point are limited. Thus, this study employed drill-down analyses, such as floor-by-floor and building-by-building examinations and used an occupant IEQ survey approach to evaluate working conditions in research buildings. This study systematically and objectively assessed IEQ using the Korea building occupant survey system. The results indicate that acoustic qualities affect the work productivity and satisfaction of the building occupants. The floor-by-floor analysis is necessary to identify IEQ factors and the reasons for the satisfaction of occupants. Additionally, it is important to improve the user-friendliness of the system, implement frequent survey distribution systems, and empirically analyze data associations among building, spatial, and demographical characteristics.

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

Environmental Quality Assessment

Michigan State University and the Michigan Department of Natural Resources established a partnership for sustainable park planning in October 2011. The purpose of the partnership was to enable students in the design fields to work on real-world projects and provide practical solutions. One of the notable projects was to assess old historic buildings in one state park and propose renovation plan to improve its indoor environmental quality and energy efficiency. The buildings in the park functioned as the traveler’s destination in the 1920s and still preserve original interior and exterior features. The team of undergraduates and faculty in interior design visited the park and assessed the interior and exterior conditions of two of its buildings. They used an assessment tool which was designed on a basis of the elements in the indoor environmental quality category (IEQ) of the US Green Building Council’s LEED. Results revealed that the indoor environmental conditions of the buildings should be improved. The energy efficiency of the buildings was low. Based on this assessment, this study offered practical suggestions for improving the building’s indoor environmental quality. This study also proposed an assessment tool for the historic buildings in the state parks in Michigan to assess current indoor environmental quality of those buildings.

Health And Well Being

Mobile health research field aims to provide access to healthcare anytime and anywhere through mobile computing technologies while using a cost-effective approach. Mobile health is closely related to ambient assisted living as both research fields address independence in elderly adults. Aging has become a relevant challenge, as it is anticipated that 20% of world population will be aged 60 years and older in 2050. Most people spend more than 90% of their time indoors, therefore the indoor environmental quality has a relevant impact on occupant’s health and well-being. We intended to provide real-time indoor quality monitoring for enhanced living environments and occupational health. This paper presents the AirPlus real-time indoor environmental quality monitoring system, which incorporates several advantages when compared to other systems, such as scalability, flexibility, modularity, easy installation, and configuration, as well as mobile computing software for data consulting and notifications. The results that were obtained are promising and present a significant contribution to the monitoring solutions available in the literature. AirPlus provides a rich dataset to plan interventions for enhanced indoor quality, but also to support clinical diagnostics and correlate occupant’s health problems with their living environment conditions.

Post Occupancy Evaluation

Green Rating Certification is one of the important mechanism developed in last few decades worldwide to achieve sustainability in Built Environment life cycle. The early generations of Green Rated Built Environment from India have occupied for several years now. Therefore, it has become inevitable to assess whether these Built Environment are living up to expectations in their objective terms. Post Occupancy Evaluation is a process of systematic monitoring of Building's performance with predefined parameters and objectives after it is occupied for few years. Present research focuses on assessment of Green Rated Built Environment on the basis of performance parameters. Indoor Environmental Quality (IEQ) and Energy Efficiency are two performance parameters identified for current research. Seven Green Rated Institutional/office projects have been selected for Post Occupancy Evaluation. Indian Green Building Council (IGBC) has rated three projects and Green Rating for Integrated Habitat Assessment (GRIHA) has rated remaining four buildings. All seven projects are located in warm and humid climatic zone of India. Questionnaire Survey, on site measurement of Indoor Environmental Quality parameters and Energy consumption records are selected as a tool to measure performance of Green rated project.
