ABSTRACT

This project aims to reconcile the existing environmental impact tools with current MSR material research to develop a methodology that can be used by the firm, in conjunction with designers and clients, to make educated material decisions that satisfy the needs for the circumstance, human health, and environment.

INTRODUCTION

MSR has the desire to make material choices that take environmental and health impacts into account. Through researching the current state of LCA tools and applying them to two MSR projects, a methodology for material selection will be developed. This methodology should not only facilitate material decision making, but should also fit into MSRâ&#x20AC;&#x2122;s design process and unique character in order to ensure its use and success. Existing LCA tools will be examined to determine their capabilities, limitations, and how they fit into the design process. These tools focus heavily on environmental impacts and tend to be less effective in measuring health hazards and responsible sourcing; therefore, findings from these tools should be paired with other resources to help make the best decisions for both clients and designers. MSR is currently undergoing material research relating to human health impacts; this research will be folded into the initiative to create a comprehensive process for responsible material selection.

Goals Help designers make informed materials choices Ensure the methodology is easy to use Produce graphical output that facilitates an understanding and a discussion of results Contextual Issues What are the critical issues of sustainable material choices? What is the current state of environmental impact estimator tools? What are the capabilities and limitations? How can the 2030 Challenge for Products be folded into the materials methodology? Methodology Create a process by examining the Itasca Biological Research Station and Laboratory with the LCA tools. Through this, limitations and capabilities of the tools will become evident. Apply the developing material analysis and impact assessment process to Aeon South Quarter IV to compare results between the two projects. Analyze Itasca and Aeon comprehensively (ie. Whole Building Analysis) as well as breaking the analysis down into assemblies: walls, floors, and roofs. Develop a template for assembly types to create an ever-expanding database to be used as reference for the office. Demonstrate how the process can be used in the office.

DEFINING THE ISSUES IMPACT OF MATERIALS + PRODUCTS According to Architecture 2030, the building sector is responsible for 49% of Annual U.S. Energy Consumption. Of this 49%, building products and manufacturing make up 5-8% of the total energy consumption.3 As buildings become more efficient from an operational standpoint, the embodied energy of building products and materials becomes more critical.

EMBODIED ENERGY VERSES EUI

Embodied Energy: The embodied energy (carbon) of a building material or product, which is expressed as the primary energy consumed, or carbon released over its life cycle, from extraction to end of life. Total embodied energy can also be classified by renewable energy and nonrenewable energy. Non-renewable energy: energy derived from fossil fuels such as petroleum, natural gas, and coal Renewable: energy from other sources such as hydropower, wind, nuclear, geothermal, biomass

EUI: EUI is a measure of the operational energy of a building and is generally expressed as energy per square foot per year. Itâ&#x20AC;&#x2122;s calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building.

Embodied Energy (Typical Residence) *Architecture 2030

Over the first 20 years of the life of a building (from today until 2030), 45% of total energy consumption is attributed to the embodied energy of building products and 55% is attributed to building operations.

On day one of a buildings occupation, 100% of the energy is embodied - embodied energy of the materials and products used in its construction. Over time, the operational energy adds up, eventually meeting the total embodied energy of the building. The relationship between Embodied Energy and EUI is complex. For an efficient building with a low EUI and a high Embodied Energy, the number of years for the EUI to catch up to the Embodied Energy will be higher than for a less efficient building. However, the high Embodied Energy associated with an efficient building typically comes from the ample amounts of insulation required for its operational efficiency. While a definitive conclusion cannot be drawn between the Operational and Embodied Energy, it is a window into the energy use of buildings, and a way to begin to understand the complex situation.

IMPACT OF MATERIALS

Understanding the environmental and health impact of materials can be difficult due to the abstract nature; it is hard to comprehend exactly what Eutrophication, for example, means to the common individual. The various impacts affect different zones and systems to varying degrees. Some impacts may remain contained within a local area, whereas others have a global impact. In addition, the impacts can affect more than one area, for instance, an impact affecting the regional environment may also spill over to affect the global environment. Below is a diagram containing a multitude of impact categories as well as their associated impact zone. GLOBAL IMPACTS: Global Warming Potential: polar melt, soil moisture loss, longer seasons, forest loss/change, and change in wind and ocean patterns Ozone Depletion: increased ultraviolet radiation Resource Depletion: [ie fossil fuel depletion] decreased resources for future generations

REGIONAL IMPACTS: Photochemical Smog: â&#x20AC;&#x153;smog,â&#x20AC;? decreased visibility, eye irritation, respiratory tract and lung irritation, vegetation damage Acidification: building corrosion, water body acidification, vegetation effects, and soil effects. LOCAL IMPACTS: Human health: increased morbidity and mortality Habitat Alteration + Ecotoxicity Terrestrial Toxicity: decreased production and biodiversity and decreased wildlife for hunting or viewing Aquatic Toxicity: decreased plant and insect production and biodiversity and decreased commercial or recreational fishing Eutrophication: nutrients (phosphorous and nitrogen) enter water bodies, such as lakes, estuaries, and slow-moving streams, causing excessive plant growth and oxygen depletion Land Use: loss of terrestrial habitat for wildlife and decreased landfill space Water use: loss of available water from groundwater and surface water sources.

A measure of air emissions that contribute to the depletion of the stratospheric ozone layer. Depletion of the ozone leads to higher levels of UVB ultraviolet rays reaching the earthâ&#x20AC;&#x2122;s surface with detrimental effects on humans and plants.

Freshwater, cultural Soil

Ground level ozone is created by various chemical reactions, which occur between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in sunlight. Human health effects can result in a variety of respiratory issues including increasing symptoms of bronchitis, asthma, and emphysema. Permanent lung damage may result from prolonged exposure to ozone. Ecological impacts include damage to various ecosystems and crop damage. The primary sources of ozone precursors are motor vehicles, electric power utilities, and industrial facilities. Ecotoxicity

EVALUATING MATERIALS LIFE CYCLE ASSESSMENT Life cycle assessment: Can either be cradle to grave (material extraction to disposal) or cradle to gate (material extraction through manufacture) While numerous LCA tools exist, the effective undertaking of an LCA is usually something undertaken by an expert. However, with the tools available, designers can choose the level of detail they desire to achieve and make quick materials comparisons. LCA provides opportunity to:

Develop systematic evaluation of the environmental consequences associated with a given product

Analyze the environmental trade-offs associated with one or more specific products/processes to help gain stakeholder (state, community, etc) acceptance for a planned action

Quantify environmental releases to air, water, and land in relation to each life cycle stage and/or major contributing process

Assist in identifying significant shifts in environmental impacts between life cycle stages and environmental media

Assess the human and ecological effects of material consumption and environmental releases to the local community, region, and world

Compare the health and ecological impacts between two or more rival products/processes or identify the impacts of a specific product or process

Identify impacts to one or more specific environmental areas of concern

EVALUATING MATERIALS LCA PROCESS â&#x20AC;&#x153;The use of LCA for buildings requires a set of guiding principles, which consider the unique character of each building design, complexity in defining systems, and related decisions.â&#x20AC;? When conducting any life cycle assessment, both the designer and LCA tool play crucial roles. At the onset of the study, the designer must establish the goal and scope. It is easy for LCAs to get unmanageable rather quickly due to the number of impact categories and materials in question. Therefore, defining the goal and scope of the study enables the designer to focus the investigation. The LCA tool handles the blunt of the work: Inventory Analysis and Impact Assessment. This is the stage where designers input the information to be analyzed and allow the tool to do the calculations. Lastly, but more importantly, the interpretation of the results. Again, this is where the original goal and scope can come in handy to aid designers in interpreting the multitude of outputs. The narrower or more focuses the line of inquiry, the easier it is to interpret results in order to make a decision. Each of these steps are related and can be altered along the way, as well as be adapted for different stages in the design process. Figure 1 LCA process diagram.

- Outputs: Releases to air, land, and water

Impact Assessment - Characterizes these inventory flows in relation to a set of environmental impacts -Impact assessment step may relate carbon emissions (a flow) to global warming (an impact)

EVALUATING MATERIALS RESEARCH PROCESS Similar to any research endeavor, this process began erratically and has slowly become more concise. At the onset of the research the investigation included three different LCA tools (BEEs, Athena, and Tally) as well as all impact categories. This resulted in a plethora of outputs, varying inputs, and an unclear strategy for interpretation. Through the process, Tally Environmental Impact Tool was chosen as the sole tool to carry forward. This simplified the process by eliminating multiple outputs, additional time, and discrepancies. Moving forward, the process can be approached with a clear issue or line of inquiry allowing the designer to isolate specific impact areas to monitor. The resulting workflow and database that was developed serves as both a point of reference as well as a strategy for testing future assemblies, materials, as well as conducting a full building analysis. A template was designed using outputs from Tally that allows all relevant material pertaining to a specific assembly to be presented in a clear manner. This is the beginning of an assembly database that can serve as reference for future projects as well as continue to grow.

EVALUATING MATERIALS LCA TOOLS The three tools have their own unique characteristics, capabilities and strengths. How the tools operate, or how they can be used varies. BEES is one-dimensional; products or materials can be selected to be compared to a similar material. Outputs can be viewed within the web browser, but it is not suitable for more complex analysis. Athena is two-dimensional; assemblies can be built and analyzed as a whole. For instance, a wall assembly can be constructed and impact outputs can be viewed relating to that assembly. Tally is three-dimensional; as a Revit plug in, it operates from geometry modelled in Revit, providing a visual representation of the geometry being studied. Tally also provides the opportunity for whole building analysis, assembly analysis as well as down to individual material analysis.

EVALUATING MATERIALS LCA TOOLS : TALLY ENVIRONMENTAL IMPACT TOOL Tally Environmental Impact Tool is a Revit plug in developed by KieranTimberlake, PE International, and Autodesk. It is the newest of the LCA tools under study. As a Revit plug in, it has many advantages. For one, as the industry shifts to using Revit throughout the design process, the plug in eliminates the need to build an additional model for analysis. In addition, unlike the other LCA tools, Tallyâ&#x20AC;&#x2122;s interface with Revit provides a three-dimensional visual for the building or assembly in question. The specific geometry, sizing, and assembly can be seen by the user and is ensured to be factored into the calculation. Tally is a powerful tool, capable of whole building analysis, assembly analysis, as well as individual material or product analysis. In addition, the tool has built in Option Comparison Analysis which interfaces with Revit. This enables quick and easy comparisons between different material options such as cladding or insulation.

EVALUATING MATERIALS OFFICE HIERARCHY Due to the complex nature of LCA and evaluating materials, a hierarchy was created for MSR, outlining what was of most importance to the office. As was outlined previously, each of the tools possesses a set of strengths, while they may be lacking in other areas. In order to address a complex set of issues, other resources may need to be referenced to gather the appropriate information. LCA tools primarily focus on Environmental impacts, leaving a void in the information as it relates to Human Health. Due to this inefficiency, other resources should be consulted where Human Health is concerned. In the case of MSR, the office has been conducting extensive research pertaining to the human health impact of materials in relation to the Living Building Challenge and the Declare Red List. Other resources exist such as the Perkins+Will Transparency List, Pharos, and GreenSpec. Below is a diagram relating the environmental and human health impacts and which tools or reference databases cover each specific category. While the LCA tools may cover human health impacts, the outputs will not be as extensive as other resources.

PROCESS PROCESS + TEST METHOD

Figure 1 Test Process + Method

In order to test the capabilities, ease of use, and workflow of each of the LCA tools, Itasca Biological Research Station and Laboratories (a MSR project currently under construction) was used as a test project. Rather than jumping directly into a full building analysis, the wall assemblies from Itasca were isolated and analyzed using the tools. Right off the batt, BEES proved problematic. The tool is meant to compare individual materials or products rather than analyzing an assembly. This study resulted in a massive spread sheet, recording outputs for each individual material. It was quickly decided that BEES was not the tool for this particular line of inquiry and was subsequently dropped. Athena and Tally however, were able to run similar sets of analysis for the wall assemblies. To ensure a level of consistency between inputs and outputs, a 10 foot by 15 foot wall was modelled in each tool. In Athena, this consisted of creating a file or project for each associated wall type and getting outputs individually. Tally on the other hand could be approached in multiple ways. There was one file with each of the Itasca wall types loaded into the file. The analysis could then either be run as a Design Option Comparison, resulting in the impacts of each wall being displayed in direct relationship to the others, or a Whole Building Analysis of each individual wall. Overall, the process and interface associated with Tally is much friendlier and less time consuming than that of Athena.

DATABASE LIMITATIONS As all of the tools come equipped with different LCA databases associated with them, there is a certain level of inaccuracy. However, any LCA conducted has a level of uncertainty. This was tracked through a matrix of inputs. The actual wall assembly was noted, along with the material available within the tool database. If the actual material was not available, a the closest possible alternative was used in its place. While not yielding perfect results, this method is still very effective.

PROCESS HOW THE TOOLS WERE USED DATABASE LIMITATIONS As stated previously, each of the tools are equipped with different databases. These range from generic materials to specific manufacturers. As the databases grow and more manufacturers submit information, the information will become more available and expansive. In their current state, each of the tools varies in what is contained in the database. Through testing, the inputs were tracked to map the actual wall assembly in comparison to what was input in each tool. An example of this matrix can be seen below. However, in moving forward, this exercise was dropped for a couple of reasons. One, in shifting to using solely Tally, this tracking seemed less effective or necessary, and two, it is time consuming., and thus hinders the process. It is to be understood that all LCA information is not 100% accurate.

PROCESS HOW THE TOOLS WERE USED After the preliminary testing involving all three LCA tools, it was decided that Tally was the more efficient, easiest to use, and generally more appealing tool. The major aspect working in Tallyâ&#x20AC;&#x2122;s favor is that as a Revit plug in, it does not require the creation of an additional model for analysis. The exchange between Revit and Tally is relatively seamless, the interface is user friendly, and itâ&#x20AC;&#x2122;s database is one of the largest and still growing. While it is not a free tool like BEES or Athena, it is the most effective tool on the market. Tally can be used to easily tackle a range of different levels of analysis, from whole building analysis, to assemblies, and down to individual materials. It essentially does what the other tools do plus some.

PROCESS HOW THE TOOLS WERE USED : TALLY In moving forward with Tally as the sole LCA tool, a strategy was developed to analyze two MSR projects: Itasca Biological Research Center and Laboratories and Aeon South Quarter IV. The analysis would look at whole building assessment, assemblies (wall, floor, roof) and individual materials. In addition to examining the projects at different levels, a database of assemblies and their impacts was begun, with the intention of it continuing to grow over time.

DATABASE DEVELOPMENT In constructing the database, initially the intention was to delve into all of the subcategories: roofs, floors, walls, structure, and glazing. However, upon undergoing the whole building analysis it was discovered that the building categories that carry the most weight in terms of environmental impacts are the walls, roofs, and floors. Therefore, the focus shifted to these assemblies. As can be seen below, the areas with the largest impacts are roofs, floors, and walls -- these categories are responsible for significantly 2% 2% 2% higher percentages of the total impacts compared to other systems 3% such as glazing, mullions, or windows. In the Aeon project, the walls account for almost half of the environmental impacts (in relation to embodied energy and global warming potential), with the floors coming in around a quarter, and the 32% roof around one-tenth. 49% In Itasca, the walls account for around forty-percent of the total impacts, with floors around twenty-percent, and the roofs from twenty four to thirty-seven percent. This clearly shows which assemblies are9% responsible for the largest environmental impacts, and thus, which 1% areas should be focused on in the design process. Global Warming Potential 6%

DATABASE TEST METHOD The development of the database and its associated template began with analyzing the wall assemblies of both Itasca and Aeon. Once the additional systems were identified (floors and roofs), the template could be designed to accommodate all of these systems in the same manner. The wall, floor or roof area was kept consistent through all tests so that the results could be cross compared. The dimensions of each are as such: Wall: 10’x15’ / area: 150 sq ft Roof: 10x10 / area: 125 sq ft Floor: 10’x10’ / area: 100 sq ft

DATABASE ABOUT At the beginning of each set of assemblies (per project) is a graph comparing all of the assemblies for that specific project and the outputs for each impact category. This gives a quick reading of which assemblies are performing better than others. However, and assembly may do well in one category and poorly in another; this is where narrowing the scope of the inquiry becomes important. The database contains various layers of information, but is intended to be a simple preliminary glance at the environmental impacts of an assembly. This database can be reviewed at the onset of a project when preliminary decisions on materials and structural systems are being made. The potential wall in question can be looked at through the lens of the impacts of different material choices. One can quickly spot problem areas (typically insulation), and choose to focus on that part of the assembly in moving forward. In addition, the template is set up in such a manner that as future projects are developed, the new assemblies can be put into the database for future use - resulting in an ever-expanding set of information.

INFORMATION The information contained within the template is a combination of Tally outputs and MSR office hierarchy. At the top there is an assembly section, whether it be a wall, roof, or floor, this can be easily pulled from DD or CD sets depending on where the project is in development. Below that is an R-Value of the assembly, if applicable. This can be an interesting piece to watch. The R-value can be tracked in relation to the impacts associated with the wall. In certain cases a lower R-value assembly will have larger impacts than a higher R-value assembly. Below this to the left are pie charts representing the Primary Energy Demand or Embodied Energy, and the Global Warming Potential, which is categorized by material. This is in relation to the 10ft x 15ft wall that was modelled in Revit, and is in relation to one another, adding up to 100%. This is a piece that can be looked at to isolate problem areas or materials (typically insulation). To the right of the pie charts are the numbers for the Global Warming Potential and Primary Energy Demand for that specific assembly. The numbers are displayed as a total, as well as by the square foot. 46

DATABASE ABOUT To the right is an example of the template constructed, with labels indicating the various pieces of information contained within it. While this does not represent the full extent of all of the environmental impacts, it is designed to quickly and easily relay information about a specific assembly. The impacts displayed were edited down to Global Warming Potential (GWP) and Embodied Energy (Primary Energy Demand); this decision was made in relation to MSRâ&#x20AC;&#x2122;s hierarchy or priority list pertaining to the environmental impacts of materials. Narrowing down the scope is effective, as it filters the information, resulting in a less intimidating or overwhelming set of information to be interpreted. The template and resulting database is not meant to stand alone, but rather serve as a reference guide. Assemblies can be compared and contrasted quickly; areas or materials of concern can be identified and monitored or tested further. Essentially, the template captures a snippet of the total environmental impacts.

DATABASE FORMAT There are a series of database files grouped in different ways. They are as follows: Itasca

ANALYSIS WHOLE BUILDING As stated previously, the databases are set up in different tiers or categories--by building project and by type. For the sake of this document, a portion of the information is presented. It is organized by whole building analysis comparing Aeon and Itasca, then goes into a few examples from each project of the wall, floor, and roof systems. The full database sets can be found in a separate document. COMPARISON The whole building analysis of Aeon and Itasca is compared in following pages. The information was filtered to examine the Embodied Energy, or Primary Energy Demand, Global Warming Potential, and Operational Energy or EUI. While these projects are of different type and scale, comparing them begins to set up a relationship between outputs.

Below is an overall breakdown of the energy use, global warming potential, and size of each of the projects. While the projects vary in size and type, comparing the size and output numbers of each begins to draw up interesting questions. Below are the total output numbers for both Itasca and Aeon. It is clear that Aeon is not only a significantly larger project as far as size is concerned, but obviously, with that greater size comes significantly higher output numbers. The total Embodied Energy of Aeon is roughly 44.8 million MJ’s compared to Itasca’s 7.2 million MJ. Also seen below is the Operating Energy of each of the projects, and again, Aeon requires more energy to operate. The Operating Energy and Embodied Energy are compared both within each project and to one another. The number of years it takes for the Operating Energy to catch up to the Embodied Energy in each project was calculated. While this is still a rough way of examining the relationship between Embodied Energy and Operational Energy, it generates useful questions.

ANALYSIS WHOLE BUILDING Below is an overall breakdown of the energy use, global warming potential, and size of each of the projects. In order to begin drawing a direct comparison, the outputs for each project were broken down into output per square foot. This way the numbers could be looked at in more of a true comparative way. However, due to the vast square footage difference between the projects, a true comparison was unable to be made. Aeon has significantly higher output numbers, coming in at 44 million kBTU of Embodied Energy, where Itasca only has 7 million. However, due to larger size of Aeon, the output per square foot of Aeon is less than that of Itasca. Itasca Biological Research Station & Laboratories Gross Square Feet:

ANALYSIS EMBODIED ENERGY + OPERATING ENERGY The following page contains a breakdown of the impacts per square foot, as well as a graph visualizing the number of years required for the Operational Energy to catch up to the Embodied Energy. On the first day of a building’s occupation 100% of its energy use is Embodied within the building products and materials. Over time, energy is exhausted through Operational Energy, and eventually, this energy use will catch up and become equal to the Embodied Energy of a building. As buildings become more efficient, with lower Operating Energy, the Embodied Energy of materials become more important. The greater the Embodied Energy and lower the Operating Energy, the longer it will take for the numbers to equal out. Aeon, with it’s significantly larger size, while possessing greater impacts, comes out looking to be in better shape than Itasca. Itasca, while it’s impacts are lower, also has a smaller footprint, resulting in higher impact per square foot numbers. While it has a high Embodied Energy (although not nearly as great as Aeon), it has a low Operating Energy of 17 kBTU/sq ft. However, this low Operating Energy and high Embodied Energy results in 37.7 years before the numbers will equal out. In the case of Aeon, the Embodied Energy is roughly 47 million MJ, but with its higher Operating Energy, it only takes 9.8 years for the numbers to equal out. BASELINE ISSUES As stated previously, these comparisons are rough in that they exist within a bubble. To date, there are no standards for building products and materials, or no average. In addition, the establishment of a baseline building is also lacking. Without a definitive baseline to compare these numbers to, they are relative to one another. However, that does not mean they are irrelevant; they generate a plethora of questions that will propel this research forward within the profession. The biggest question through this whole project has been focused around what the outputs mean. How is the office doing in the grand scheme of things? Are their energy efficient buildings performing efficiently in terms of environmental impact? Are they doing well, average, or poor? What is the target zone?

ANALYSIS BASELINE + COMPARISON ISSUES Unfortunately, to date, there exists no averages or targets for the environmental impacts of materials and building products. Architecture 2030 is developing a 2030 for Products framework, which will establish product category averages. Essentially, the averages will act as a bench mark to measure a projects impacts against. Similar to the initiatives energy goals, the target impact decreases in intervals over the years leading up to 2030. In an attempt to begin developing some way to compare the impacts of Aeon and Itasca, the comparison was extended to a brief study of office buildings in Chicago and New York. The energy information pertaining to the Chicago and New York buildings came from the AIA 2030 Annual Report. The Operating Energy, Embodied Energy, and time it takes for the numbers to meet was compared across the office projects and the MSR projects in question. Similar to other comparison attempts, it exists in a bubble, and raises more questions than it answers. However, it does outline a few relationships. If a project has a high Embodied Energy with a low Operating Energy, the number of years it takes for the numbers to meet will be greater than if the project has both a high Embodied Energy and high Operating Energy. The relationship between Embodied Energy and Operating Energy can be seen here to the left. The two are inextricably linked; as one number changes, so does the other. In addition, the energy (embodied or operating) is also tied to the size of the project, the floor area to envelope ratio, and the expected lifespan of the building. In essence, it is a complicated relationship that has yet to be fully resolved.

ANALYSIS TALLY OUTPUT_AIDING FOCUS The information on this page is merely an example of a different way of evaluating the outputs from a whole building analysis from Tally. The program outputs the information in various ways; depending on the line of inquiry, different output styles are more informative than others. Below each project is a graph output from Tally. It contains each impact category with the total impact broken down by CSI division. This is just one of many different output styles available from Tally. This is what is so nice about the program --the output can be chosen based on the line of inquiry, and which issues the designer is tracking. The CSI graph below allow easy identification of problem areas, as does the output categorized by material entry. It is easy to see at first glance which categories are causing the greatest impact, providing focus for future analysis and study. It isolates which part of an assembly or is resulting in the highest impacts, and provides a focused WHOLE BUILDING building ANALYSIS trajectory for designers wishing to reduce the environmental impacts of their designs.

ANALYSIS DATABASE_WALL ASSEMBLY SUMMARY Figure 1 Wall Assembly Summary page from the wall database

The following pages include portions of the database for both Aeon and Itasca. For the sake of keeping this document slightly smaller, the database(s) in their entirety can be found in a different document. There is a separate database for Wall Types, Floor Types, and Roof Types. In addition, a Full Building Analysis of both Aeon and Itasca, as well a comparison document can be found on the server. Below is the Itasca wall type summary page. The summary page begins each portion or project within the Wall Type Database. The graph is an output from Tally, resulting from a Design Option Comparison Analysis. This type of analysis is helpful in that it allows the user to see the various wall assemblies in direct comparison to one another across the impact categories. This demonstrates again how complex this analysis can get. One wall may be performing well in one category but poorly in another. This is why establishing a goal and scope at the onset of the study is valuable; it allows the user to focus or target a certain aspect rather than trying to juggle all of the variable at once.

ANALYSIS DATABASE_WALL ASSEMBLY EXAMPLES To the right are three of the five Itasca wall types. To view all of the walls analyzed see the Wall Type Database. The template developed allows for a quick comparison between wall types. The idea is that walls existing in the database can be reviewed early in the process of a new project, to aid in making early material and assembly details. Further information on the assemblies can be found in the full Tally outputs. As new wall types are developed they are added to the database.

ANALYSIS ITASCA_ASSEMBLY CHANGE The study to date was based off the of the Construction Document set for Itasca, however, like with many projects, the assembly changed along the way due to cost. The whole building analysis has been updated to reflect the recent changes to the wall assembly, however,, the wall assembly database remains based off the original CD set. Wall 1 was adjusted to match the new assembly and the results were compared against one another. The changes were minor, but had a relatively high impact on the results. The overall Global Warming Potential went down in the new assembly, while the Embodied Energy went up, but also resulted in a lower R-value assembly. ORIGINAL ASSEMBLY • 5/8 Gypsum wall board • 3-1/2” Mineral fiber blanket insulation • 3-3/4” Closed cell polyurethane spray foam • 1/2” Plywood sheathing • Air barrier • 2” Semi-rigid mineral fiberboard insulation • 1” Semi-rigid mineral fiberboard insulation • Hardie Lap Siding • LVL framing UPDATED ASSEMBLY • 5/8 Gypsum wall board • 3-1/2” Mineral fiber blanket insulation • 2-1/2” Closed cell polyurethane spray foam • 1/2” Plywood sheathing • Air barrier • 2-1/2” Extruded Polystyrene (XPS) • 1” Semi-rigid mineral fiberboard insulation • Hardie Lap Siding • LVL framing

ANALYSIS DATABASE_WALL ASSEMBLY SUMMARY To the right is the Wall Assembly Summary for Aeon. Here, eight exterior wall types can be seen next to one another. On the top runs a small strip of wall sections, identifying the wall types that were analyzed. Again, as this is the summary graph, it is meant to be used for an overall look at the wall types in question. More in depth information relating to each wall can be found in the individual wall information slice following. Yet more information can be found in the full Tally results. The Database and its assembly slices are essentially filters for the vast amount of information that Tally outputs. The summary is the first quick glance, the assembly slice reveals yet more information, allowing for more in depth comparison between assemblies, and the comprehensive report can be found in the full Tally output. As the users questions become more specific, different resources are consulted.

ANALYSIS DATABASE_WALL ASSEMBLY EXAMPLES To the right are three assembly slices of the total eight that were analyzed. Again, the user is provided with a quick overview of the wall type, its Global Warming Potential and Primary Energy Demand. This is broken down in the pie charts by CSI division so that different materials can be isolated in relation to the overall impact. It can be noted that while Wall AAA has a higher R-value that Wall 3A, its Global Warming Potential per square foot is significantly lower.

ANALYSIS DATABASE_FLOOR ASSEMBLY SUMMARY Below is the Wall Assembly Summary for Aeon. Here, eight exterior wall types can be seen next to one another. On the top runs a small strip of wall sections, identifying the wall types that were analyzed. Again, as this is the summary graph, it is meant to be used for an overall look at the wall types in question. More in depth information relating to each wall can be found in the individual wall information slice following. Yet 100% more information can be found in the full Tally results.

3.513 kgSO2eq

The Database and its assembly slices are essentially filters for the vast amount of information that Tally outputs. The summary is the first quick glance, the assembly slice reveals yet more information, allowing for more in depth comparison between assemblies, and the comprehensive50% report can be found in the full Tally output. As the users questions become more specific, different resources are consulted.

The assembly slice for the Itasca floor can be seen below. While the floor has a low Global Warming Potential, the Primary Energy Demand is significantly larger by comparison. Also, the assembly only contains a few materials, but concrete and its associated reinforcing are responsible for the bulk of the environmental impacts.

Aeon, being a larger project, contained five different floor assemblies that were analyzed with Tally. Below is the summary of the five assemblies compared against one another. Here again it can be seen that one assembly may perform well in one impact category and poorly in another. Decisions should take into account multiple aspects, and balance the environmental impacts. The following page includes the database information for three of the five floor assemblies. The full analysis can be found in the Floor Database file.

ANALYSIS DATABASE_FLOOR ASSEMBLY EXAMPLES To the right are three of the five assembly slices for the Aeon project. It can quickly be seen that the assemblies containing concrete have a larger Global Warming Potential and Primary Energy Demand than the assembly that does not.

Similar to what has been presented previously, the Itasca Roof Assembly Summary can be seen below. At first glance, it can be seen that Roof C is performing poorly in relation to the other roof types as far as Ozone Depletion Potential, but better than Roof A in Smog Formation Potential. This is a way to quickly isolate assemblies and their potential problem areas in relation to the different impact categories. The full analysis can be found in the Roof Database file.

ANALYSIS DATABASE_ROOF ASSEMBLY EXAMPLES Below is the roof assembly slice for Aeon. As was found in other sets of assembly slices, the Thermal and Moisture Protection materials are responsible for the bulk of the environmental impacts. In most cases ROOF-1 this is linked to insulation. While responsible for the largest portion of environmental impacts, insulation is extremely valuable in its ability to increase a buildings operational efficiency. This again shows the complex relationship between operational energy and embodied energy. While insulation will drive up the embodied energy of a building, it will lower the operational energy. Here is where decisions and compromises must be made on a project by project basis. MEMB-2

ANALYSIS DATABASE_INDIVIDUAL MATERIALS The power of Tally extends beyond full building or assembly analysis and into that of individual materials. The following pages include results from two different studies. The two studies focused on different insulation and cladding. The assembly remained constant, with the individual materials swapping out and being analyzed in relation to one another. This is an extremely powerful option in the design process. When deciding on which cladding, insulation, structure, etc to use, a quick study can show the environmental impacts of each different material choice. In some cases, a certain material must be used, however, if a few options are available, this form of analysis reveals the impacts of each material, and thus the decision. This can be used to aid in determining which material or product is best for the project, client, or situation. TALLY WHOLE BUILDING

ANALYSIS DATABASE_CLADDING SUMMARY Below is the summary chart from the cladding study. Again, the rest of the assembly was consistent between the three, while the cladding material was altered. Similar to the summary charts seen previously, a certain wall, or in this case cladding, may perform well in one category but poorly in another. For instance, Terracotta is generally resulting in lower environmental impacts than the other two materials, however, in the case of Primary Energy Demand, it results in a greater impact.

ANALYSIS DATABASE_INSULATION SUMMARY The study below focuses on different insulation types. Again, the rest of the assembly remained constant, while the insulation type was changed. At first glance, closed-cell spray foam appears to be resulting in the largest environmental impacts. However, it is highly efficient as an insulator; to reach the same R-value with a different insulation typically results in a much deeper wall assembly and more material. So in cases where a high R-value is desired while keeping a shallower wall, closed-cell spray foam may be the best option. Insulation tends to be the material responsible for the greatest impacts, but also serves to lower the operational energy of a building. This again demonstrates where clear priorities and goals should be established in running analysis and making decisions in respect to different projects. AEON SOUTH QUARTER IV GRID

CONCLUSION

While this research covers a lot of ground, it is but the beginning of something larger. The profession is still searching for benchmarks to compare environmental impacts and to help gauge how we are doing in relation to this. While murky at this point, as more research is done, solutions will become more clear. The most important part of this process is to bring the environmental impact of materials into the conversation. As the profession continues to investigate the impacts of the projects that are built, the knowledge base will grow. Similar to the advances we have been making in relation to the operational energy of buildings, as focus expands to include the embodied energy of materials, we can only get better. OFFICE INTEGRATION Discussions went on throughout this process on how to best relay information to the office and encourage conversations and use of this information and tool. The goal is to fold this into the design process of every project. While training an entire office in how to use a tool would be helpful, it would also be resource and time consuming. Therefore, the best way to ensure continued use and the dissemination of information is through a small group of â&#x20AC;&#x2DC;experts.â&#x20AC;&#x2122; Ideally, each project team will have someone versed in this knowledge and passionate about making a change. Through this, the conversations will expand and knowledge grow.
