Sustainable Portland: Implementation Series 1, New England Environmental Finance Center Apr 2008

Sustainable Portland: Implementation Series 1, New England Environmental Finance Center

Climate Change

When the Sustainable Portland Task Force Report was released in November 2007, under the leadership of Mayor Jim Cohen, Portland Councilor Kevin Donoghue had the idea that students at the Muskie School of Public Service might be able to help implement recommendations from the report. It may have helped that Kevin was himself a graduate of the Community Planning and Development Master’s program at the Muskie School, but it was a good idea nevertheless. He approached Professor Sam Merrill in the CPD program, who spoke with the new Mayor Ed Suslovic about a possible partnership between the City and the …

Evaluation Of A Virtual Refrigerant Charge Sensor, Woohyun Kim, James E. Braun, Haorong Li Jan 2008

Evaluation Of A Virtual Refrigerant Charge Sensor, Woohyun Kim, James E. Braun, Haorong Li

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents a thorough evaluation of a method for determining refrigerant charge that employs low-cost, non-invasive measurements (i.e., surface mounted temperature measurements). The method could be used as part of a protocol for verified service providers (VSPs) in AC diagnostic tune-up or refrigerant charge, air flow (RCA) verification programs. Ultimately, the method could be embedded within a portable virtual refrigerant charge gauge for a technician’s use or permanently installed on the AC unit. The accuracy of the virtual refrigerant charge sensor method is evaluated in this paper using laboratory data for a number of different systems and over a …

Incorporating Value And Risk Management Principles In Developing Low-Income Housing Projects, Ayman Ahmed Ezzat Othman Jan 2008

Incorporating Value And Risk Management Principles In Developing Low-Income Housing Projects, Ayman Ahmed Ezzat Othman

Architectural Engineering

The construction industry is concerned with satisfying its customers’ needs through delivering projects that achieve their objectives and meet their expectations on time, within budget and as specified. Despite the several housing programmes constructed by government authorities, there is a real housing problem for the poor. This problem is attributed to a number of reasons. Amongst them, the inability of the low-incomers to cover the cost of supplied houses and the lack of the constructed projects to achieve users’ satisfaction. This highlighted the need to develop innovative and creative solutions that can deliver housing projects that achieve the satisfaction of …

Behaviour Of Reinforced Self-Consolidating Concrete Frames, Aly Said, Moncef Nehdi Apr 2007

Behaviour Of Reinforced Self-Consolidating Concrete Frames, Aly Said, Moncef Nehdi

Civil and Environmental Engineering and Construction Faculty Research

Multi-storey reinforced concrete (RC) structural frames represent some of the most congested structural elements. Placing and consolidating concrete in such structural frames imposes substantial challenges. This offers a unique area of application for self-consolidating concrete (SCC) because of its inherent ability to flow under its own weight and fill congested sections, complicated formwork and hard-to-reach areas. Research is, however, needed to demonstrate the ability of SCC structural frames adequately to resist vertical and lateral loads. In the present study, full-scale 3 m high beam-column joints reinforced as per the Canadian Standards CSA A23·3-94 and ACI-352R-02 were made with normal concrete …

Augusta Me: The New Bridge Begets A New Planned Neighborhood, Molly Pulsifer, Richard Barringer Aug 2006

Augusta Me: The New Bridge Begets A New Planned Neighborhood, Molly Pulsifer, Richard Barringer

Planning

Construction of a new Third Bridge over the Kennebec River in Augusta offered the prospect of a new and handsome gateway to the city. Further, the resulting change in traffic patterns offered the City the chance to plan for a pattern of development quite different from what the city had experienced for the past half-century. The case study describes the planning and construction of the new bridge and corridors that re-routed traffic out of Augusta’s downtown and older neighborhoods, and created the opportunity for planned development adjacent to the corridor created by the new bridge. It goes on to describe …

Thermal Performance Of Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn Apr 2006

Thermal Performance Of Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Conference Papers

Meteorological enthalpy analysis of temperate and maritime climates above 45˚N suggests that the water-side evaporative cooling technique has considerable unrealised potential with contemporary "high temperature" building cooling systems - such as chilled ceilings. As low approach conditions are the key to exploiting the cooling potential of the ambient air, thermal performance at such conditions needs to be investigated. To address the research issues a test rig, based on an open cooling tower and plate heat exchanger and designed to maximise evaporative cooling potential, has been constructed at DIT. A combination of experimental measurement and analysis is used in the investigations. …
