Arpad Horvath Associate Professor Department of Civil and Environmental Engineering University of California, Berkeley February 14, 2007

2 Outline of Presentation
Where is sustainability research today? Sustainability research at UC Berkeley Players, networks, timing, trends Joint opportunities Involvement of industry

3 The Grand Vision: Sustainable Development
Definition: Meeting the needs of the current generation without sacrificing the ability of the future generations to meet their needs. (Brundtland Commission, 1987) Maintain societal progress while improving environmental quality and quality of life Environmental goals reduce non-renewable resource use manage renewable resource use for sustainability reduce toxic substance emissions (heavy metals, solvents,) reduce greenhouse gas and ozone depleting substance emissions Educate the stakeholders Do good by doing well profit = revenue - cost

4 The Triple Bottom Line of Sustainability
Environment Economy Social issues

We have the p2 program here. mostly operates in the manuf and repair/maintenance phases. Some in the disposal phase, but limited thinking involved. Leads to process or site specific improvements Bulk of DTSC work is in the disposal phase- mostly compliance oriented. Opportunity to move beyond the traditional compliance realm of DTSC What about the longer term – product lifetime and beyond to sustainability concepts LCA is a tool to evaluate all aspects of the whole life cycle. A systems tool for moving to the industrial ecology realm and to provide metrics for sustainability. Helps to look at intelligent design and eliminating waste. Helps to look at industrial metabolism. Opportunity for dtsc is to move from a compliance role to a product stewardship role Courtesy: B. Boughton, DTSC

7 Characterizing Sustainability Research
~ 30 years of publications and projects 1st phase: “we have a global problem” Mostly descriptive, qualitative Stated problem, categories of effects (e.g., air emissions), but few numbers 2nd phase: “let’s analyze/blame someone” – low hanging fruit Industries: automobile, chemical, petroleum, electric power, cement Advent of industrial ecology, life-cycle assessment (LCA) Mostly incomplete assessments (e.g., not all life cycle phases, inventory but no impact assessment) Initial savings by companies 3rd phase: more specific assessments Data collection for specific studies Services and network analysis, not just manufacturing processes and products Supply-chain informed LCA Advances in impact assessment

8 Observations about Sustainability Research
1. Need to incorporate triple bottom line: environment, economy, equity - need a unified theory and implementation to link them 2. Sustainability solutions are integrated solutions - Need to learn from successful businesses 3. Need to assess a broad range of environmental effects – sustainability is not just about energy! 4. Need international networks for research and projects 5. Need quantitative studies 6. Need to analyze services, not just products and processes

15 Buildings and the Environment
Buildings integral part of infrastructure systems (or “civil systems”), and the boundaries between these terms are fuzzy The built environment has a large impact on the natural environment, economy, health, and productivity Buildings account for 17% of world’s fresh water withdrawals, 25% of world’s wood harvest, and 40% of world’s materials and energy flows

16 U.S. Buildings and the Environment
The construction industry accounts for ~8% of U.S. GDP Similar in industrialized countries, even bigger economic share in industrializing countries U.S. construction industry larger than the GDP of 212 national economies (CA’s: 150 economies) 54% of U.S. energy consumption is directly or indirectly related to buildings and their construction In the U.S., buildings account for 65% of electricity consumption 30% of GHG emissions 30% of raw material use 30% of waste output (136 M tons annually) 12% of potable water consumption

17 Categories of Natural Resources
Energy Raw materials Land/Habitat Terrestrial Ecosystems Marine Ecosystems Biodiversity etc.

18 Ecosystems and Biodiversity
Terrestrial and marine ecosystems greatly endangered Loss of forest, oil spills, overfishing, etc. Current rate of extinction is several orders of magnitude greater than the natural background In the U.S.: over 500 known species are now extinct 1,200 species listed as endangered

23 Urban Sustainability Initiative
Joint effort of UC Berkeley, the U.S. National Academies, and non-governmental organizations (Urban Age, Healthy Communities Network) Goal: combine cutting edge research and development with innovative capacity building programs and a global information & exchange network to foster the spread of effective urban sustainability practices and technologies in growing cities throughout the developing world. Facilitate linkages between project partners, local scientific communities, civil society, the private sector and the official leadership of rapidly growing cities; Accelerate the application of existing technologies and practices, and the development and demonstration of new technologies and practices that improve the environment; Creating an extensive urban sustainability information network to share technologies and best practices for the benefit of cities around the world. Create “living laboratories” in cities in Asia, Latin America, and Africa, and to test new approaches of environmentally sustainable urban development.

Universities Carnegie Mellon, Michigan, Arizona State, Texas, Washington Research labs (e.g., Lawrence Berkeley National Lab) The leaders are ICT companies LEED as a green scoring system

30 Exciting Times in the U.S….
AB 32, Global Warming Solutions Act, by 2020, return GHG emissions to 1990 levels (and boost annual GSP by $60B and create 17,000 jobs) UC Berkeley’s $500M Energy Biosciences Institute (BP-funded) U.S. considering GHG reduction legislation and industrial action The Economist, 4/29/04

31 Greening Building Practices in China
Tasks: Assess the current construction practices of commercial buildings and high-rise residential buildings in China. Recommend environmentally less burdensome building materials and processes. Short term: Focus on major materials (e.g., concrete, steel, aluminum, flooring, with special focus on cement) and processes (e.g., construction equipment, temporary materials). Later: evaluate the engineering, economic and environmental feasibility of using waste materials and byproducts (such as fly ash, demolition material, waste tires) in construction.

32 Indoor Air Quality in China
Task: Assess the effect of the indoor environments on building occupants. What are the indoor air quality (IAQ) implications of using common building (e.g., carpet and paint) and maintenance materials (e.g., cleaners)? What are the IAQ implications from the introduction of pollution from outdoor air? China has severely polluted urban air and might consider IAQ control by means of filtering supply air in addition to controlling indoor emission sources.

33 Opportunities to Use Innovations in Practice
Need to get all the stakeholders networking and integrating (clients want intergated, packaged services, want to deal with one company) Need to get problem focused problems are global GHG and other environmental studies of U.S., Chinese, Indian, etc. companies, industries, government entities ICT industry: Data centers study, construction, operation Biofuels Lean and green

34 Connecting Green and Lean: Project Production Systems Laboratory
Develop new project management theory based on understanding of production systems (esp. Toyota Production System) Reform project management practice Purposes Design Criteria Concepts Process Product Detailed Engineering Fabrication & Logistics Installation Commissioning Operations & Maintenance Alteration & Decommissioning Project Definition Lean Design Lean Supply Lean Assembly Use Production Control Work Structuring Learning Loops Take a holistic view on project delivery – cradle to grave. Understand the value different stakeholders can bring but recognize that the current system is working far from optimal. Lean ideal it to Deliver what the customers want (= PROVIDE VALUE) In no time (= INSTANTANEOUSLY) With nothing in stores (= NO INVENTORY) This is in an ideal, will never be reached, but something to strive for through continuous improvement.

35 Opportunities in Research and Development
Location: U.S., Europe, China Transformational, interdisciplinary research and development Modeling of infrastructure Sustainability metrics E.g., green building scoring system for the EU LCA model for Finland, Nordic countries, EU Data centers Computer-based decision-support tools Education Joint educational initiatives in, e.g., China

36 Opportunities for Industrial Involvement
GHG developments in California, U.S., China, India Scientific and management knowledge transfer, consulting service industries, and their supply chains have a tremendous opportunity to present a unified product (e.g., Bechtel, Xerox, Kodak) ICT industries Biofuels Data centers ICT products/services helping urban communities (e.g., telework, mobile work) Green does not have to be synonimous with cheap Green can bring competitive advantages

38 Industrial Ecology “The (deliberate and rational) concept requires that an industrial system be viewed not in isolation from its surrounding systems, but in concert with them. It is a systems view in which one seeks to optimize the total materials cycle from virgin material, to finished material, to component, to product, to obsolete product, to ultimate disposal. Factors to be optimized include resources, energy, and capital.” – Graedel and Allenby

39 Future Work Continued adaptation of the latest environmental science and management methods and results hybrid LCA Need to assess indirect as well as direct environmental effects, and reveal the supply chain implications Takeback, recycling regulations Revisit past research questions, and redo some analyses Quantify the benefits on society Focus on impact assessment, not just on inventory Embrace analysis of social effects

40 Future Plans Campus research center in “Technology and Sustainability.” Formalize “Technology and Sustainability” certificate program. Accelerate research on green and lean project delivery. Develop green modules for engineering courses. Involve more faculty in teaching and research.

Sustainable Livable Engaging Transit oriented Wired Renewable ENR, March 12, 2001, Cover Story

45 Characteristics of Civil Systems
Products and processes Manufacturing and service Long service lifetimes Slower obsolescence (?) compared to industrial products Large, complicated, in the public eye Considered “underfunded”, “in bad shape” (ASCE Report Card 1998, 2001, 2005) Decisions have significant economic, environmental and social consequences

46 Current Issues - General
Visual and physical impacts of infrastructure Reduction of materials use End-of-life options: landfilling, reuse, recycling Environmental discharges (to air, water, land and underground wells) in all phases of construction Hazardous and non-hazardous waste generation and disposal Environmental efficiency of construction equipment Energy implications of construction etc.

47 Current Issues - Specific
Toxic chemical emissions Conventional pollutant emissions Greenhouse gas and ozone-depleting chemicals use and emissions Embedded energy in construction materials Energy consumption by construction machines Nonrenewable and renewable resource use Reuse and recycling of construction materials Solid and nonsolid waste implications etc.

48 Existing Solutions Rating tools EIA LCA
So what’s currently being done in order to evaluate and minimize the impacts of buildings? There are 3 main classes of tools used for this purpose…. Rating tools consist in certification schemes that give credits for specific “green features” that are included in the building EIA are a more generic tool, used for many other kinds of projects (actually rarely used for a single building) which perform their analysis in a local context. They include public participation and discussion of a final report: Env. Impact Statement which put very simply highlights the problems with a specific project and sets up minimization and monitoring measures. And finally we have LCA tools. As I will explain in more detail later in the presentation, simply put these tools perform an inventory of inputs and outputs and then they assess the overall environmental impact. This is the class of tools that interests me the most for this research.

49 How Much Material Do We Use?
A total of 2.8 billion metric tons of different materials used in the U.S. in 1995 (USGS) ~3.5 billion metric tons in 2000 81% by volume were construction materials, mostly stone, and sand and gravel

50 Use of Construction Mineral and Material Commodities in the U.S. [ton]
cement crushed stone dimension stone coal combustion products iron and steel slag construction sand and gravel 1950 40,891,000 228,000,000 1,890,000 22,600,000 321,000,000 1960 55,526,000 557,000,000 2,250,000 26,100,000 628,000,000 1970 67,476,000 788,000,000 1,830,000 4,630,000 30,600,000 830,000,000 1980 70,173,000 893,000,000 11,300,000 22,900,000 692,000,000 1990 80,964,000 1,110,000,000 3,680,000 19,300,000 22,100,000 831,000,000 2000 110,470,000 1,569,000,000 5,850,000 28,600,000 17,500,000 1,120,000,000 Ewell ME (2001), Mining and quarrying trends.

51 Current Design Method Current building design decisions are made based on: Safety Functionality Cost Environmental issues are often only addressed qualitatively or simplistically (e.g., using recycled-content flooring or lead-free paint) Goal is to meet the user’s needs with a factor of safety at the lowest economic cost possible

52 Objectives of Horvath’s Research Group
Material and energy resource consumption Environmental impacts of onsite construction processes Overall life-cycle impacts of construction Decision support tool for the building industry

53 Generic Impact Category
Our Comprehensive Framework Construction Design Operation Maintenance End-of-life Air Emissions Water Emissions Waste Emissions Water Materials Energy Labor Equipment Finance Direct Impacts Indirect Impacts Generic Impact Category Materials Production To answer this question I developed a generic framework that allows to see that to execute a comprehensive evaluation of the impacts we need to have both breath of analysis (by looking at all the life-cycle phases) and depth of analysis (by looking at all the supply chain). Or in other words we need simultaneously to be concerned with scope and detail.

54 Generic Impact Category (Literature on Buildings)
Scope and detail of our analysis Generic Impact Category Indirect Impacts Direct Impacts Exists Missing Legend: (Guggemos, 2003) (Literature on Buildings) Construction Design Operation Maintenance End-of-life Materials Production Detail Scope If the framework I presented before shows what needs to be done, this slide shows what was already done by other authors in the LCA area. Particularly by Angela…. This slide also shows that we are still missing a very significant portion of the picture in the way we currently conduct impact assessment. As a consequence (next slide)

72 Bren School Emissions Analysis
Use phase dominates energy, CO2, SO2, and NOX emissions Materials production dominates CO emissions PM emissions are similar in the materials and use phases Overall, construction is a small part of life-cycle environmental impacts, but as use phase becomes more efficient, the materials and construction phases are expected to increase in significance The end-of-life phase is also small, but more research, more detailed assessment is needed Maintenance phase emissions are similar in significance to the construction phase

74 Connecting Green and Lean: Project Production Systems Laboratory
Develop new project management theory based on understanding of production systems (esp. Toyota Production System) Reform project management practice Purposes Design Criteria Concepts Process Product Detailed Engineering Fabrication & Logistics Installation Commissioning Operations & Maintenance Alteration & Decommissioning Project Definition Lean Design Lean Supply Lean Assembly Use Production Control Work Structuring Learning Loops Take a holistic view on project delivery – cradle to grave. Understand the value different stakeholders can bring but recognize that the current system is working far from optimal. Lean ideal it to Deliver what the customers want (= PROVIDE VALUE) In no time (= INSTANTANEOUSLY) With nothing in stores (= NO INVENTORY) This is in an ideal, will never be reached, but something to strive for through continuous improvement.

75 Conclusions LCA necessary for better decision-making throughout the life cycle of a building Control electricity and natural gas use with efficient design Control materials and maintenance impacts by material choices LCA should permeate green building scoring systems (e.g., LEED) We are creating a decision-support tool for total building LCA (BuiLCA)
