Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu

Articles

Although embodiedCO2-eq analysis has seen recent developments as evident in the establishment of the ISO14040 and 14044 LCA standards, it is recognized that due to weaknesses in gathering data on product-related emissions,embodiedCO2-eq values are probabilistic. This paper presents a stochastic analysis of hybrid embodied CO2-eq in buildings to account for this weakness in traditional methods and, by way of example, applies it to an Irish construction-sector case study. Using seven apartment buildings, 70,000 results are simulated with Monte Carlo analysis and used to derive probabilistic and cumulative embodied CO2-eq intensity distributions for apartment buildings in Ireland. A Wakeby distribution with …

Thermal Bridging - Understanding Its Critical Role In Energy Efficiency, Joseph Little, Beñat Arregi

Articles

Plane element heat loss[1] and thermal bridging[2] together constitute all the conduction heat loss (measured in W/K, watts per kelvin) through the thermal envelope[3] of a building. Perversely insulating the plane elements more and more without carefully dealing with junctions can lead to a significant increase in thermal bridging heat loss. This is often more significant in poorly thought-out energy-focused retrofits than in existing or new buildings.

Hybrid Cooling Systems For Low-Temperature Geothermal Power Production, Andrea Ashwood, Desikan Bharathan

Publications (E)

The overall objective of this investigation is to identify and evaluate methods by which the net power output of an air-cooled geothermal power plant can be enhanced during hot ambient conditions using minimal amounts of water.

Geothermal power plants that use air-cooled heat rejection systems experience a decrease in power production during hot periods of the day. This decrease in power output typically coincides with the time when utilities need power to address high air conditioning loads. Hybrid cooling options, which use both air and water, have been studied for this report to assess how they might mitigate the net …

Publications (E)

The U.S. Department of Energy (DOE) Building Technologies Program has set the aggressive goal of producing marketable net-zero energy buildings by 2025. This goal will require collaboration between the DOE laboratories and the building industry. We developed standard or reference energy models for the most common commercial buildings to serve as starting points for energy efficiency research. These models represent fairly realistic buildings and typical construction practices. Fifteen commercial building types and one multifamily residential building were determined by consensus between DOE, the National Renewable Energy Laboratory, Pacific Northwest National Laboratory, and Lawrence Berkeley National Laboratory, and represent approximately two-thirds …

Social Space catches up with the social space maverick in his eco-office in the tranquil setting of a wooded area off Dairy Farm Road.

Industrial Evolution: A Comparative Case Study Of The Transformation Fron Industry To Leisure In The Ports Of San Francisco And Oakland, California., Annie Fulton

Inquiry: The University of Arkansas Undergraduate Research Journal

This case study examined two waterfront sites on the San Francisco Bay – The Piers in San Francisco and Jack London Square in Oakland. The Piers, actually consisting of Piers 1 ½, 3 and 5, was formerly the point of entry for immigrants to the city and today is home to offices and restaurant space. Jack London Square, which covers four city blocks, is a project whose aim is to revitalize an industrial shipping port and warehousing district. Today, it is about halfway through its phased development schedule. Multiple techniques were used to investigate the process by which these two …

Godot In Bombay: A Tragicomedy In Two Decades, Lisa Björkman

NAKHARA (Journal of Environmental Design and Planning)

An exploration of the two-decade-long political and discursive battles over water "privatization" in the Indian city of Mumbai reveals how, beginning in the 1990s, the water department, "got stuck inbetween public and private infrastructures." This essay demonstrates how widespread speculation among policymakers, bureaucrats, and engineers on the likelihood and desirability of privatization entrenched some of the very dynamics that such solutions were supposed to cure - dynamics that ironically, would ultimately derail a privatization initiative when it fi nally arrived.

The Changing Role Of Water In The Spatial Construction Anddesign Of Southeast Asian Polities, Lily C. Wong

NAKHARA (Journal of Environmental Design and Planning)

Investigating historical maps and texts, this essay charts the changing role of water in the spatial understanding and city design of three consecutive polities in Southeast Asia: pre-colonial tributarysystem, modern nationhood during the colonial period, and contemporary globalized neoliberal government. The role of water shifts from a heuristic device that is interwoven with political and territorial imaginings to a technocratically engineered commodity that is sacrificed in pursuit of modernization. Using the current urban design of Phnom Penh, Cambodia as an example, water remains the blind spot for urban development, despite the discussion of water sustainability at the regional scale.

Readdressing Dhaka's Public Water Bodies: A Design Research, Sanne Peeters, Kelly Shannon

NAKHARA (Journal of Environmental Design and Planning)

In Dhaka, the capital of Bangladesh, rampant expansion and commercial development are brutally transforming the urban tissue. As a consequence, Dhaka's water network, which was once integratedinto the city's fabric and is of major importance for its drainage capacity, is rapidly disappearing. This article critically investigates the layered meanings of water in the city through focusing on the case study of Hatirjheel Lake, Dhaka's largest inner-city water body. A number of interpretative maps dissect the rich history of the city and its water, while contemporary cartographies reveal a new set of issues as advancing urbanization fi lls in water bodies. …

Ngibikan Villagespirituality Design In Javanese Architecture, Johannes Adiyanto, Josef Prijotomo, Galih Widjil Pangarsa

NAKHARA (Journal of Environmental Design and Planning)

In May 27, 2006, a massive earthquake hit and destroyed Ngibikan, a small village 17 kilometers south of Yogyakarta, Indonesia. Yet, in a few days, the villagers rose up and reconstructed not only theirhouses but also their daily life. In this case, architectural design includes not only building as a material practice but also a humane and spiritual one. This essay employs combined methods of contextual criticism (Attoe, 1978, pp. 103-104) and hermeneutics as modeled by Paul Ricouer (2006). The results of this research also indicate the importance of understanding that the act of emergency rebuilding is not only about …

In the fi rst part of this article the topographic and architectural structure of the region is introduced, and in the second part, specifi c sections of this region have been analyzed in terms of modernity in relation to the hidden identity …

From The Origin Of Drawing To Cinemetrics, Cheng-Luen Hsueh

NAKHARA (Journal of Environmental Design and Planning)

Robin Evans in his article "Translations from Drawing to Building" explores the gap and transitive properties between architectural drawing and building (1997, p186 - 187). He concludes with somequestions arising from the allegorical painting by Giacinto Brandi depicting a portrait of a courtesan holding a divider. In contrast to the architect/geometer in William Blake's painting "Ancient of Days" which from the architect's point of view relates more to conventional measurement, precision, perfection, and also projection, the Giacinto painting may tell a story of architecture's mediation and negotiation in-between drawing and building under the prejudice or shelter of these big conventions …

Architectural Representation Of Islamic Modernism In Indonesia Case Study: Architecture Of Achmad Noeman, Agus S. Ekomadyo

NAKHARA (Journal of Environmental Design and Planning)

Islamic modernism appeared as a reformation movement based on two main ideas: purifying norms by rejecting deviation from religious practices, and adopting new ways of thinking to adapt to the modernworld. In Indonesia the movement had an important role in the development of modern Islamic organizations and Islamic intellectuals. This movement had a special representative in the architecture of Achmad Noeman. Noeman is a modernist Muslim, and also a modernist architect; his architecture refl ected modernism in Islam and in architecture. His designs infl uenced later Indonesian architects to interpret Islam rationally, critically, and creatively in endorsing Islamic building design. …
