Creating Energy Efficient, Green Homes from Abandoned Properties in Aurora
Presentation given by Mike O'Connell at the Green Buddha Sustainability Center's grand opening on June 5, 2014
The document summarizes renovations and an extension to convert an apartment house. The original house was a luxurious single-family home with a large central hall and indoor pool. It was taken over by two families who converted the basement for one of the families. Later, to accommodate another son returning, the architect added another apartment by building around the large central hall and renovating the ground floor and upper floor, including a new guest apartment. The renovations included facing concrete walls and a curved wooden shell to bring more light into the building. Large frameless glass areas reach from floor to ceiling, except for conventional windows in the kitchen and shower.
The document describes a dilapidated abandoned house from the 1920s that is surrounded by a junkyard. The property has numerous code and safety violations including an illegal trailer park with unpermitted utilities connected to the house. The house has extensive structural damage and many repairs have been done improperly or are already failing. Plumbing and electrical systems need complete renovation due to backed up drainage and non-functioning fixtures. Nearby comparable properties have recently sold for between $25,000 and $70,000.

This document summarizes the construction of a new home with a focus on sustainability and energy efficiency. Key details include installing insulation, using double glazed windows, orienting the home towards winter sun, reusing materials from the original structure, and sourcing local and recycled materials. The end result was a home that improved on its initial zero energy rating and performed well in minimizing energy consumption and environmental impact.
Shipping container homes offer an affordable housing solution. Used shipping containers are modified by cutting openings, adding windows and doors, and connecting containers together to form multi-story structures. Containers are placed on foundations like concrete footings or slabs and equipped with utilities like electricity, plumbing, and solar panels. Case studies show container homes can be constructed quickly for low costs and provide durable housing in various applications. However, issues with heat control and potential chemical contamination from prior cargo need to be addressed.
Building an A-rated Home - Back to the FutureEd O'Donoghue
This is a presentation from 9 years ago outlining how the first A-rated homes in Ireland were constructed. As of now (2016) this level of house performance is becoming the basic house standard in Ireland. This presentation shows how a double leaf masonry construction can achieve high levels of energy efficiency.
The Elements House is a 4,600 square foot single family home in Berkeley, CA designed by Studio URBIS. Some key details:
It was completed in 2013 on a 10,000 square foot lot. The architect of record was Renee Chow and the project was led by Thomas Chastain and Antje Steinmuller. Significant sustainability features include the use of recycled materials from a previous home, protection of trees during construction, and drought tolerant landscaping. Parallel walls structure the spaces on the narrow lot and natural lighting is provided through courtyards and retaining walls.
The 12 Container House is a 4000 square foot home built in 2003 from 12 recycled shipping containers. It has a T-shaped design with two stories, floor to ceiling windows, and radiant floor heating. On the ground floor, the containers form the side walls and are open to reveal the kitchen and living area. Two steel staircases in the containers lead to the bedrooms on the second level. It is considered one of the premiere examples of shipping container architecture.

Ultimate green building lime & industrial hemplimetech
This document summarizes the construction of a community center building using hempcrete, a building material made of hemp shiv, lime, and water. Over three days, volunteers removed wood siding from the existing building to use as shuttering forms and installed 320 cubic feet of hempcrete on the interior and exterior walls. The hempcrete was mixed by hand, shoveled into place in layers, and tamped down. Once dried, the interior walls will receive lime plaster and the exterior will get a lime render finish and limewash coating. The project demonstrates the use of hempcrete, a sustainable building material made from hemp and lime.
This document discusses Passive House principles for highly energy efficient building. It outlines typical issues with code-built homes like heat loss and drafts. The key Passive House principles are then introduced: thick insulation, airtight construction, thermal bridge-free envelopes, high-performance windows, and fresh air supply. Cost analyses show that while initial costs are higher, overall lifetime energy savings result in cost effectiveness. Examples are given of Passive House projects completed by Placetailor, including multi-unit developments in Boston that achieved net-zero or net-positive energy usage.
This design is for a private residence located at Chanonry Point. It is a one and a half storey building clad in local stone with a Spanish slate roof. The wrap-around design provides protection from winds and maximizes the limited space. It has generously sized bedrooms, two living rooms, and a snug area. Triple glazing and high insulation will keep heating costs low. The orientation takes advantage of views and sunlight.

This case study describes the rehabilitation of a 1940 home in Petaluma, CA into a net zero energy live/work building. The owners purchased the home in 1997 and conducted extensive energy efficiency upgrades, reducing energy use by 75%. A second remodel phase in 2005 added photovoltaic panels, solar air heating, and a wind turbine to provide all electricity and ventilation. The home now produces more energy annually than it uses, meeting the Thousand Home Challenge goal of reducing energy use in existing homes.
The document presents diagrams for a sustainable housing design called the 3+1 b2 House in New Orleans. It utilizes several passive design strategies to reduce energy needs including cross ventilation through a longitudinal hallway and floor vents, stack ventilation with high ceilings and operable windows, and raised foundation to allow air circulation. Other strategies are daylighting from north-facing windows, deep overhangs, a rainwater cistern, and solar photovoltaic panels on the south-facing roof. The design is derived from traditional New Orleans "camelback" housing adapted for sustainability and alternative family living patterns.
This document describes a two-family home design by Waggonner & Ball Architects. The design is based on the camelback shotgun prototype found in New Orleans. It consists of two nestled forms - a two story, three bedroom unit joined to a one story, one bedroom unit. The larger unit has two bedrooms and a living/dining area on the main floor, and a master bedroom in the "camelback" on the second floor. The smaller unit has a living room, kitchen, and master bedroom. The home is designed to harvest rainwater and solar power.
Fiona and Nigel built their home on 25 acres of land in New Zealand with views of the Southern Alps mountains and Canterbury plains. Their home took 8 months to construct and features 4 roofs, engineered timbers, and reinforced concrete walls to withstand the high wind, snow, and earthquake zones. The 3 bedroom, 2.5 bathroom home has large windows throughout to take in the scenic views and modern amenities like a kitchen with granite counters, indoor and outdoor living spaces, and an insulated structure built to last.
Retrofitting your home involves making improvements to increase energy efficiency and lower heating bills. Some effective retrofits include attic insulation, draft proofing, wall insulation, upgrading heating systems and controls, and installing more efficient windows. The Sustainable Energy Authority of Ireland offers grants for home energy upgrades that can improve a home's Building Energy Rating. Attending an upcoming event hosted by the local organization The Green Village is recommended to learn more about practical retrofitting options and get advice on getting started with a retrofit project.

"From Laneway House to Passive House to Net Positive"
With many nations declaring 'climate emergencies' it's clear that we need to aggressively target the greenhouse emissions coming from our buildings and cities, but - to do that - we need to go beyond our current approach to 'green building' and instead shift our thinking to a target of 'Net Positive' impact.
This presentation will frame an approach to net-positive development that unfolds from a decade's worth of experience with infill housing and passive house projects.
Four learning objectives:
1. Defining 'Net Positive' in comparison to the Passive House standard, 'Net Zero', 'Energy Positive' and other green building benchmarks
2. Understand how site history and location contribute to the net GHG impacts of a development project
3. Understand how upfront emissions and operating emissions can be minimized with wood frame passive house projects.
4. Become familiar with Lanefab's "Net Positive Lens"; a framework through which we can critique the climate impact development projects

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
