The document provides information about a material phase life cycle assessment (LCA) conducted for the Center for Sustainable Landscapes (CSL) building in Pittsburgh, Pennsylvania. The LCA focused on the embodied energy and environmental impacts of the building materials used in construction. Concrete and steel contributed the most impacts due to their use in the building's foundations, structure, and envelope. Photovoltaic panels and inverters also had sizable impacts, accounting for 16% of global warming potential. The CSL had 10% higher global warming potential than standard commercial buildings due to its energy reduction systems like photovoltaics and geothermal wells. The LCA identified opportunities to reduce impacts through material substitutions and increased recycling.
The goal of this discussion is to demystify building performance modeling. Computer-simulations give you a more complete picture of how various context and design factors can affect the performance of your space. Modeling information can help you analyze the impacts of your design decisions and determine how to most effectively meet project goals.
Energy modeling is also valuable tool used for code compliance and LEED points. Not to mention the fancy graphics that models produce to show your clientele your commitment to performance-based design.
This discussion will present various opportunities that can arise from building performance simulations with analysis at the early design, whole building, and building component levels. We will examine the following types of analysis:
• Climate
• Daylighting
• Massing and orientation
• Whole building energy usage forecast
• Fenestration design
• Façade development
• Zone level energy performance
• Baseline and design case models
• System selection and optimization

Green buildings aim to reduce these environmental impacts through efficient energy and water use, renewable materials, and reducing waste. The first LEED-certified commercial building in Nigeria is highlighted as an example. The document argues that adopting green building standards and certification systems, updating building codes, training professionals, and integrating green practices into government policy can help promote sustainability in the construction sector in Lagos.
The document provides an environmental impact assessment for installing green roofs on the NYU Polytechnic campus. Green roofs would provide multiple environmental benefits such as reducing air pollution, absorbing heat to reduce building energy costs for cooling and heating, managing stormwater, and increasing roof longevity. The proposed action is to install an extensive green roof system, requiring little maintenance, on the roof of one campus building. Extensive green roofs are estimated to reduce energy consumption and greenhouse gas emissions while providing other sustainability benefits. The assessment will evaluate impacts to land use, socioeconomics, open space, and other environmental factors.
Growing and potential impacts of climate change, such as flooding in coastal areas, change in weather patterns, and melting of the permafrost have created new challenges for the engineering and construction industry. These challenges involve adaptation in the design and construction of projects to address these impacts, as well as developing ways to reduce and controlling greenhouse gas (GHG) emissions to mitigate climate change.
Engineering has the lead responsibility for determining the technical feasibility and cost parameters to overcome these challenges. Engineering and construction projects are implemented with the help of a set of standard documents that lay out the work process of the projects. They include standard design detail drawings, standard design criteria, standard specifications, design guides and work process flow diagrams. Incorporating in these standard documents materials and processes which assist project engineers to identify and assess climate change related impacts can be a major step in effectively preparing to meet the challenges of climate change mitigation and adaptation.

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.
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.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
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.
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.

2. Introduction
• As the number of low-energy buildings increases, the need to
consider embodied energy from building materials increases,
especially if an overall goal is to reduce the building’s life cycle
energy use.
• The Center for Sustainable Landscapes (CSL) is a three-story,
24,350 square foot educational, research, and administrative
office in Pittsburgh, PA, USA.
• This is a net-zero energy/water building, which aims to achieve
significant benchmarks in the United States—the Living Building
Challenge and LEED Platinum, and SITES certification for
landscapes.
• Focus on materials was because of other studies, which
suggested that the materials used to construct green buildings
have higher environmental impacts than those of traditional
buildings
3. About the Building
• Using an integrated project delivery system, the project owner,
architects, engineers, and contractors designed the CSL to be
a facility that combines passive solar design, geothermal wells,
photovoltaics, solar hot water collectors, a constructed lagoon
and wetland system, permeable paving, and a green roof.
• The CSL is 3 stories with cast-in-place concrete and steel
framing for the structure and aluminum/glass curtain wall and
wood cladding for the envelope while the roof is a
combination of a green roof, paver patio, and thermoplastic
polyolefin white roof.

8. 4 phases of LCA According to ISO 14040 standards
Phase 1
•goal and scope definition, establishes the boundary conditions of the system, defines a
functional unit for the system, and enables equivalent comparisons with other products or
processes.
Phase 3
•Life Cycle Inventory (LCI), data is aggregated to determine the aggregate inputs and
outputs. In the case of a building materials study, this is often the quantity of materials used as
well as the emissions associated with the production of those materials.
•Task 2
Phase 2
Phase 4
•Life Cycle Impact Assessment (LCIA), the LCI is translated using characterization factors, into
impact categories, such as global warming potential and ecotoxicity.
• interpretation, where data and results are analyzed to determine areas of relatively high
environmental impacts and recommendations are made for improvements to the system.
9. LCA Boundary Definitions
• This LCA focuses on the environmental impacts of CSL’s
building materials. The boundaries for this study include
material extraction and product processing and
manufacturing (defined herein as “materials phase”) of the
CSL.
• The building material phase is becoming increasingly important
as the impacts associated with the use phase of low-energy
buildings decreases. The functional unit of this study is defined
as the entire CSL building.
• The major components of the analysis range from structural
elements to interior flooring as well as ductwork for the
Heating, Ventilation and Air Conditioning (HVAC) system and
piping for plumbing. This LCA also includes the production
phase of the photovoltaic (PV) panels as well as the
geothermal heat wells.
11. LCI Data Sources
• Material inventory data was obtained through CSL’s project
documents, including estimates, plans, and specifications
provided by the architects and the pre-construction
management company.
• Materials were allocated to a representative LCI unit process
within an environmental impacts database, with preference
first given to the US based material process database Franklin
USA 98 [34].
• When Franklin USA 98 was insufficient to represent the material,
ecoinvent was used [35].
• If a unit process was not available in either Franklin USA 98 or
ecoinvent, another database was selected based on the best
possible information of the unit process description, boundary
considerations, and installed productuse.

14. Impact Assessment Methods
• The LCIA phase was conducted using two impact assessment methods.
• First, embodied energy of the materials was calculated using a
Cumulative Energy Demand (CED) method developed by ecoinvent
• The remaining environmental impacts were calculated using TRACI ( Tool
for the Reduction and Assessment of Chemical and Other Environmental
Impacts), was developed by the Environmental Protection Agency (EPA)
as a US-based impact assessment method.
• The impact assessment categories reported from TRACI include -
1. global warming,
2. acidification,
3. human health cancer,
4. human health noncancer,
5. human health criteria air pollutants,
6. eutrophication,.
7. ecotoxicity,
8. smog,
9. natural resource depletion,
10. waterintake, and
11. ozone depletion
15. Life Cycle Environmental Impacts of Building Materials
•In general, eitherthe
foundations and excavation or
structure categoriesof the CSL
represented the highest
environmental impact in nearly
every impact category
analyzed.
• Concrete contributes an
average of 73% of the
environmental impacts for the
excavation and foundations of
the building, and steel
contributes an average of 59%
of the environmental impacts
for the structural system of the
CSL.
•The electrical system (PV
panels, inverters)& plumbing
system, also represents high
environmental impacts.
Life cycle impact of building materials by building system for
net-zero energy building (HH = human health).
16. •Other significant materials
include gravel, crystalline
silicone associated withthe
PV panels, and electronic
components associated
with the inverters.
•Due to the intense process
of mining gravel, including
machinery, electricity, and
hazardous waste disposal,
in conjunction with the
release of particulate
matter, gravel has high
human health impacts in
both cancer and non-
cancer categories
Life cycle environmental impacts of building materials by material type for
net-zero energy building (PV = photovoltaic).
Life Cycle Environmental Impacts of Building Materials
17. • For PV panels, the high waterintake category is a result of heat
recovery units withinthe PV system and preventionof dust
accumulation, which inhibits solar efficiency.
• Inverters required to utilize the PV panels contain many electronic
components, which are associated witha high level of toxicity risk.
Componentssuch as the integrated circuit, wiring board, and
inductor contribute to global warming potential, whilethe copper
wiringcontributes to categories such as acidification, eutrophication,
and human health impacts.
• Standard structures do not generally include PV panels in the
material phase as they utilize the grid or natural gas as primary
energy sources for the use phase. However,PV panels as a
renewable, non-fossil based fuel source reduce the impacts during
the use phase of the building’s life cycle and reduce the total
environmental impacts of the CSL when allocated overthe building’s
lifespan.
Life Cycle Environmental Impacts
18. Building and Material
properties for case study
comparison
•The differences between
environmental impacts of this
net-zero energy building and
a standard structure largely
result from unique design
components such as passive
solar, natural ventilation, and
a
green roof.
•The LCA of the CSL identified
concrete and steel as
materials with the largest
relative impacts.
•An overview of the
traditional
structures compared to the
CSL is summarized in this
Table.
19. GLOBAL WARMING
POTENTIAL
•The CSL was compared
with and withoutthe
inclusion of the PV panels,
inverters, and the
geothermal wells, due to
the fact that they are not a
common material.
•The results show that PV
panels and inverters
account for approximately
16% of the total GWP, while
the geothermal wells
account for 5% of the total
GWP for the CSL.
•For all structures, concrete
and steel accounted for a
large range of results, 11%
to 65% and 17% to 38% of
the buildings’ total GWP.
Global warming potential of the CSL compared to the published results.
PV = Photovoltaic & Inverters; GW = Geothermal Wells; Note: The
Kofoworola ’07 study did not report glass separately from other materials; it
is therefore represented in the“other” category.
20. Embodied energy comparison between the Net-Zero Energy CSL building
and published LCA building studies;
PV = Photovoltaic & Inverters; GW = Geothermal Wells;
Note: Junnila ’03 and Kofoworola ’07 did not report on embodied energy.
EMBODIED ENERGY
COMPARISON
•The PV panels and
inverters represent 49% of
the total embodied energy
and the geothermalwells
account for approximately
4% of the total embodied
energy of the CSL. High
levels of energy are
required for the production
of the PV panels and
inverters, contributing to
the high levels of
embodied energy.
•For all structures, concrete
contributed 7% to 28% and
steel, 12% to 42% of the
total embodied energy,
respectively.
21. • Concrete and steel, the majority represented by the excavation and
foundations and structural building systems, represent the highest
environmental impacts in most categories.
• Gravelmakes up a noticeable impact in the human health
cancerous and non-cancerous categoriesof the CSL, whilethe
production of PV panels and inverters makes up over50% of water
intake and eutrophication impacts.
• It is important to identify those materialswithinthe building system
that have the greatest effect on a building’s environmental impacts
in order to target specific areas for minimizing environmental impacts
in future construction.
• Comparing LCA results of the building to standard commercial
structures reveals that the addition of the CSL’s energy reduction
systems, such as PV and geothermal wells, results in a 10% higher
global warming potential and nearly equal embodied energyper
square foot relative to standard commercial buildings.
Conclusion
22. • Compared to using 100% Portland cement, the use of 40% flyash for
cement replacementreduced concrete’s overallGWP contribution
by 39%.
• Incorporation of engineered cementitious composites instead of
conventional steel expansion joints can reduce life cycle energy
consumption by 40%, waste generation by 50%, and raw material
consumption by 38%.
• For steel, stainless steel production incorporates the use of 33% of
recycled steel, which accounts for 3.6 kg of carbon dioxideemissions
per 1 kg of stainless steel produced. Theoretically,the use of 100%
recycled content in the production of stainless steel would result in
1.6 kg of carbon dioxidereleased for every 1 kg produced, or a 44%
overall carbon dioxide reduction.
• Applied to the CSL, the 100% recycling process would reduce carbon
dioxideby 85,000 kg and the total global warmingpotential for the
CSL building by 8%.
