Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang Sep 2019

Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang

Publications and Research

The current methods for the prediction of the heat flow through building entrance doors have been used for years while involved with a certain degree of uncertainty. This paper describes an experimental method that accurately quantified such heat flow. The experiment monitored local environmental parameters in a college building on a cold winter day. The results of the experiment demonstrated that the experimental method is viable to accurately estimate the heat flow throughout the entrance doors and the presence of a vestibule moderated heat losses from the conditioned area. The results will be used for validating the existing methods.


Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand Sep 2019

Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand

Publications and Research

A spray PDEC system has been relatively less considered than other passive cooling strategies as one of the viable low-energy solutions in the cooling of buildings while having a great potential in energy savings. This study is intended to evaluate the capability of a spray PDEC system for space cooling. It comprises four simulation scenarios to see the system response and influence of indoor thermal environment when a spray PDEC system is adopted as a primary cooling system in two different climates. The simulation results show that a spray PDEC system causes a substantial variation in the indoor thermal environment ...


What Is A Bim Design Model?, James Peters, Malachy Mathews Jan 2019

What Is A Bim Design Model?, James Peters, Malachy Mathews

Conference papers

The recent report into Building Information Management or BIM, by construction law experts May Winfield and Sarah Rock entitled “Winfield Rock Report” [1] gives reason to state that the UK architectural, engineering and construction industry or AEC, is hindered by the absence of a clear definition of Level 2 BIM. The ISO 19650-2 standard published in 2019, is based upon PAS1192-2:2013. The intent of ISO 19650-2 is to provide a road map to facilitate the standardisation of BIM process in a uniformed fashion. A key pillar of ISO 19650 is the “information cycle” and central to this is a ...


An Integrated Experimental-Computational Investigation Of Connected Spaces As Natural Ventilation Typologies, Ulrike Passe, Baskar Ganapathysubramanian, Shan He, Kyle Vansice, Songzhe Xu May 2016

An Integrated Experimental-Computational Investigation Of Connected Spaces As Natural Ventilation Typologies, Ulrike Passe, Baskar Ganapathysubramanian, Shan He, Kyle Vansice, Songzhe Xu

Architecture Conference Proceedings and Presentations

This paper investigates the impact of spatial composition on the effectiveness of passive cooling by natural ventilation in a comparative study of the conical roofed Harran houses in Turkey and a passive solar home in the Midwest of the United States. While the projects are distinct and are situated in two extreme climate zones (hot and arid and continental humid) both projects have in common open variable configurations of multiple interconnected spaces. Computational fluid dynamics (CFD) simulations using OpenFoam were used to investigate the fundamental airflow characteristics and the resulting interior temperature and velocity profiles. The simulations were initialized as ...

Umass Amherst Energy Modeling Guidelines, Nariman Mostafavi, Ted Mendoza, Jeffrey G. Quackenbush, Sandy J. Beauregard, Jason J. Burbank, Mohamad Farzinmoghadam, Ludmilla Pavlova-Gillham, Kylie A. Landrey

Campus Planning Reports and Plans

Facilities & Campus Services, Sustainable UMass and Campus Planning support sustainability and energy conservation initiatives by providing in-house resources to campus staff as well as designers and contractors working with the University. The Campus energy Modeling Guidelines were developed in 2015 as a resource on how to: i) generate energy models for campus buildings; ii) provide quality assurance review of current energy models; and iii) share UMass Amherst energy modeling input parameters with project design teams for them to establish a baseline building energy profile.


Umass Amherst Building Measurement, Verification, Coordination And Template Plan, Nariman Mostafavi, Ted Mendoza, Jeffrey G. Quackenbush, Sandy J. Beauregard, Jason J. Burbank, Mohamad Farzinmoghadam, Ludmilla Pavlova-Gillham, Kylie A. Landrey, Patricia O'Flaherty Jan 2015

Campus Planning Reports and Plans

Facilities & Campus Services, Sustainable UMass and Campus Planning support sustainability and energy conservation initiatives by providing in-house resources to campus staff as well as designers and contractors working with the University. The UMass Amherst Building Measurement, Verification, Coordination and Template Plan was begun in 2013 and finalized in 2015 as a resource to project teams that undertake the measurement and verification of building systems during the first year of occupancy of a new building and renovation project, particularly projects undergoing LEED certification.


Educational Programmes For Spatial Information Sciences In The Dublin Institute Of Technology, William Prendergast, Eamonn Murphy, Audrey Martin, Avril Behan Jan 2014

Educational Programmes For Spatial Information Sciences In The Dublin Institute Of Technology, William Prendergast, Eamonn Murphy, Audrey Martin, Avril Behan

Conference papers

The ever increasing spatial information needs of society, the rapid development of new surveying technologies, and the global demand for appropriately qualified surveyors, have triggered a radical re-evaluation of geomatics education worldwide. Significant enhancements have been made to the educational programmes in the spatial information science discipline in the Dublin Institute of Technology’s (DIT) during the last decade including the provision of a BSc in Geomatics and various masters’ programmes to cater for the increasingly specialised needs of the Geographic Information sector in Ireland.

University Of Massachusetts Amherst 2012-2021 Capital Improvement Projects, Douglas Vigneau, Juanita Holler, University Of Massachusetts Building Authority, John Mathews, Ludmilla Pavlova-Gillham, Ezra Small

Campus Planning Master Plans

In 2013 the University of Massachusetts, on behalf of the University of Massachusetts Building Authority and Massachusetts Division of Capital Asset Management and Maintenance (DCAMM), submitted an Expanded Environmental Notification Form for the University's 2012 - 2021 Capital Improvement Plan to the Executive Office of Energy and Environmental Affairs (EOEEA) Massachusetts Environmental Policy Act Office (MEPA).

Taken individually, the majority of the Projects, comprising of 13 building/space, 7 site/landscape, and 5 facility/ utility scale improvement projects, do not require MEPA review as most of the Project sites are confined to infill areas on campus that are currently or ...

Development Methods And A Scenegraph Animation Api For Cluster Driven Immersive Applications, Brandon J. Newendorp, Christian J. Noon, Chiu-Shui Chan, Eliot H. Winer, James H. Oliver Jan 2009

Development Methods And A Scenegraph Animation Api For Cluster Driven Immersive Applications, Brandon J. Newendorp, Christian J. Noon, Chiu-Shui Chan, Eliot H. Winer, James H. Oliver

Mechanical Engineering Conference Presentations, Papers, and Proceedings

This paper presents a scenegraph animation application programming interface (API), known as the Animation Engine, which was constructed for software developers to easily perform smooth transitions and manipulations to scenegraph nodes. A developer can use one line of code to enter the property, end state and number of frames to describe the animation, then the Animation Engine handles the rest in the background. The goal of the Animation Engine is to provide a simple API that integrates into existing applications with minimal effort. Additionally, techniques to improve virtual reality (VR) application performance on a large computer cluster are presented. These ...
