How do you design a durable, sustainable, and financeable Net Zero Energy house for a cold weather climate using little or no external energy that is also affordable? Reviewing all of the factors that would influence the design and materials selection of an appropriate response to the issues, the perfect system for housing people, whether it is in response to affordability, durability, comfort, cultural sensitivity, appearance or being locally appropriate, is using some kind of straw bale construction system with an integrated frost protected shallow foundation and a SkyTherm North design.
The focus and intention of this research is to …
Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Master's Theses
Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.
In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …
Building Envelope For Energy-Efficient Residential Homes, A Case Study For The U.S. Department Of Energy Challenge Home Student Design Competition, Milica Tajsic
UNLV Theses, Dissertations, Professional Papers, and Capstones
With the continuous rise of population and expansion of urban areas, the need for additional housing and infrastructure is growing rapidly. Building sector is consuming a vast majority of the natural resources to meet the needs of urbanization and is in need of efficient, sustainable solutions that are viable for the customer, the economy and the environment. The building sector is both the problem and the solution to the issues of the carbon footprint of our society (Architecture 2030, 2011).
The envelope (roofs, walls, and foundations) and windows typically account for 36% of overall energy use, or about 14.3 quads …
Deep Energy Retrofits Using The Integrative Design Process: Are They Worth The Cost, Daniel S. Bertoldi
Deep Energy Retrofits Using The Integrative Design Process: Are They Worth The Cost, Daniel S. Bertoldi
Master's Projects and Capstones
The McKinsey Global Initiative identified existing building retrofits as an integral component to achieve a 75% reduction in greenhouse gas emissions in the United Sates by 2050 (Fluhrer, Maurer, & Deshmukh 2010). However, this will require energy efficiency retrofits for existing buildings to be deployed more frequently and achieve higher energy savings on average. Deep Energy Retrofits using the Integrative Design Process can result in 30-60%+ energy savings in office buildings. Because Deep Energy Retrofits require higher upfront capital costs, in an economy still recovering from the economic downturn, financial decision makers may not be inclined to invest more capital …
Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker
Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker
2014 Student Theses
Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication …

Recovering The Moca River: An Exploration Through Sustainable Strategies For Developing Countries, Marleny Santana Diaz
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Natural watercourses are being negatively affected by growing urbanization in different cities of the world. Within these circumstances the concept of river restoration has gained relevance, becoming a worldwide priority in water management. In developing countries, river restoration plans, conditioned by social and economic limitations, are mainly focused on a single approach, typically relying on short-term, low technology strategies.
In the long term, these strategies tend to fail because they usually avoid integral solutions that address the interconnected factors contributing to river degradation. Therefore, the purpose of this study is to develop a framework of river restoration planning for developing …
