Advance Glazing System – Energy Efficiency Approach for Buildings a Review
No full textAbstractEnergy conservation and energy management has become a matter of concern since last few decades. Window and glazing plays an important role in building energy management. In this regard, glazing technology has gone through rapid evolution. Numerous research and development in glazing fabrication techniques have led to a wider range of design options. Visual transmittance of the glazing unit is important as it determines the amount of daylight through the glazing unit. So, the desired criteria of a glazing system from energy savings point of view is that it should possess higher transmittance in visible spectrum and lower transmittance in infrared region. To check the performance and durability of the glazing systems, thorough research works has been carried out under different conditions. In this paper, an overview of different types of glazing units and their performance has been discussed. A comparison regarding thermal properties of different types of glazing units is also carried out
Performance Evaluation of a Guarded Hot Box U-value Measurement Facility under Different Software based Temperature Control Strategies
No full textAbstractEnergy conservation and energy management can be achieved in buildings by reducing the load on the HVAC systems used in the buildings. This is possible by reducing the magnitude of heat flow through the building materials and components such as the windows, ceilings, floors, walls, etc. The thermal performance of a material can be evaluated by measuring its overall heat transfer coefficient or the U-value. The U-value of a material can be measured using the Guarded Hot Box method. The setup comprises of three parts – the metering box, the guard box and the cold box. In this method a constant heat flow needs to be maintained through the test specimen from the metering box to the cold box. Thus it is important to control temperatures in all the three parts accurately. In the present work the temperatures of the metering box and the guard box have been controlled using three different software based temperature control strategies. In the first two strategies on-off control was implemented while in the third strategy proportional control was implemented. From the experimental data it was found that similar performances were obtained in the first two test cases where the temperatures could be controlled satisfactorily. Whereas, in the third case steady state offset was obtained while controlling the metering box temperature and the guard box temperature showed fluctuations

No full textThis is my (Subhasis Chattopadhyay's) draft of PhD pre-submission. Dr. Scriver has (had) put it up online in her blog and I found it today, that is 1:06 pm, 28th May, 2017. I am grateful to her since intellectual ideas can otherwise be hijacked. She has done a wonderful editorial job. I want to make it clear that the author of the blog post is Dr. Scriver and not I. But in the Add Contributor here I cannot insert her name as the author so I have out her as an editor which is incorrect. Her blog-post though is in the public domain.

State of the Raritan Report, Volume 1, December 2016
No full textThis report updates key indicators of water quality and watershed health for the Raritan Basin that were originally assessed in the 2002 Raritan Basin: Portrait of a Watershed as developed by the New Jersey Water Supply Authority. The objective of that original report, as well as this update, is to inform watershed management and water supply protection needs in the Raritan Basin. This new assessment uses the same eleven key indicators and updates the original data – most from 1986 and 1995 – with data from 2002, 2007 and 2012 in order to determine trends over the past 26 years and to identify data gaps for development of future more comprehensive assessments.Eleven key indicators were assessed for this report including: population; housing units; urban land use; impervious surface cover; forested, coastal and emergent wetlands; upland forest cover; prime agricultural land; groundwater recharge; fish and macroinvertebrate bioassessments; riparian area integrity; and known contaminant sites and groundwater contamination. Overall comparison of this updated analysis with the prior 2002 report (Table 1) shows that trends evident between 1986 and 1995 are continuing in the same general direction though the rate has varied over the longer time period. Trends increased for population, housing units, urban land use and impervious surface cover. An increasing trend for these indicators adds stress on water quality and supplies with potential negative impacts for the watershed. Trends declined for all of the wetland land covers assessed as well as for upland forest, prime agricultural land and groundwater recharge. Downward trends for these indicators suggests that the watershed is losing its natural filtering capacity with attendant negative impacts to water quality. The bioassessment and riparian areas trends were mixed and there was not sufficient data to determine trends for the known contaminated sites and groundwater contamination indicators.more information about report and effort at: http://raritan.rutgers.edu/2016-state-of-the-raritan-report/Authored by the Sustainable Raritan River Initiative.

The Specious Present: background for my students (special author Virginia Woolf)
No full textThis 4 slides' presentation is supplementary material for my students who have opted for Virginia Woolf as their Masters' 'special author'. The presentation shows how James' the specious moment and Husserl's the rough now constitute the matrix of modernist literature, especially the fiction of Virginia Woolf. From St. Augustine to Husserl there is a continuum which has to be understood for engaging with the novels of Virginia Woolf
