Integra(ve Design & Carbon Neutrality For A Sustainable Singapore Singapore Environment Ins1tute Professional Sharing Series Members of: MEWR Hall March 30, 2015 © Climate Resources Exchange (2014) Pte Ltd Objectives • • • • Improving knowledge on real, long-term and measurable sustainability Assisting leaders and managers to stay relevant and competitive, in the local and global context Provide solutions to meet CSR and mandatory requirements under the ECA Develop meaningful action plans moving forward © Climate Resources Exchange (2014) Pte Ltd 2 What We Do • Integrative Design to reduce CAPEX and OPEX • Holistic Carbon Neutrality Solutions © Climate Resources Exchange (2014) Pte Ltd 3 Whole systems approach • Solving a systemic problem requires a holistic approach • Systems thinking = holistic approach • Integrative design uses systems thinking © Climate Resources Exchange (2014) Pte Ltd 4 The whole systems approach to reducing capital and operating costs • High performance design deals with a complex web of interrelated issues • This complexity cannot be addressed through a “broad brush-stroke” or single issue approach • Efficiency requires “designing out” technical complexity and cost by carefully rethinking, challenging and improving • A well-defined, collaborative, integrated multi-disciplinary team process is essential = © Climate Resources Exchange (2014) Pte Ltd 5 Whole systems thinking • The process of understanding how things influence one another within a whole o In nature, various elements must work together in ecosystems o In buildings, all the components that make up the building must work together • Solve ‘problems’ by viewing them as parts of an overall system, rather than reacting to specific parts, outcomes or events o Piecemeal approach potentially creates unintended consequences. An improvement in one area of a system can adversely affect another. o Small catalytic events can cause large changes in complex systems © Climate Resources Exchange (2014) Pte Ltd 6 Whole systems thinking • Most people think that efficient systems are about energy efficient equipment and expensive gadgets. • This is like saying that using the best ingredients will ensure a tasty dish. © Climate Resources Exchange (2014) Pte Ltd Courtesy Eng Lock Lee Whole systems thinking But the finest ingredients won't make our dish tasty unless: • We use a good recipe • The recipe combines the right ingredients… • …in the right manner and proportions © Climate Resources Exchange (2014) Pte Ltd Courtesy Eng Lock Lee Make decisions based on lifecycle costs, not just first costs Procurement costs Life cycle costs to all of us © Climate Resources Exchange (2014) Pte Ltd 9 What is IDP? • IDP is the most effective process for exploring and implementing sustainable design principles on a project while staying within budget and program schedule constraints. • The process is essential to achieving high performance (sustainable) buildings while avoiding or minimizing incremental costs • Requires a multi-disciplinary and collaborative team • Follows the design through the entire project life, from predesign through occupancy and into operation • Can be used for both new and existing buildings. Don’t replicate the old mistakes. • LEED/Green Mark is not the same thing as IDP © Climate Resources Exchange (2014) Pte Ltd 10 Factor Ten Engineering (10xE) • Factor Ten Engineering (10xE) aims to help engineers, architects and their clients attack resource-intensive design problems, such as manufacturing/industrial processes and facilities using whole-system principles in order to produce fundamentally better results. • 10xE currently offers design principles and a growing set of case studies over several projects and as pioneered by RMI. Rather than a rigid formula, 10xE is a set of ideas for shaping the design space and design approaches within it. These ideas will be used by those purchasing or approving design services, as well as design practitioners. • CRX facilitates the exchange of expertise by and between the design team and consultants. The approach also allows for solutions to be presented at the outset to be followed through from construction through operations. © Climate Resources Exchange (2014) Pte Ltd 11 Integrative Design Opportunities Opportunities to engage integrative design © Climate Resources Exchange (2014) Pte Ltd 12 Reducing Resource Consumption from operations Efficient' servicing' strategies' Design' $$$' E User' behavioural' change' Y' G' R' E N Passive' design' measures' Opera,on' $' Improved' controls' © Climate Resources Exchange (2014) Pte Ltd 13 The Differences Integrative Design Process vs Conventional Design Process Inclusive from the outset vs Involves team members only when essential Front-loaded — time and energy invested early vs Less time, energy, and collaboration in early stages Decisions influenced by broad team vs Iterative process vs Whole-systems thinking vs Allows for full optimization vs Seeks synergies vs Life-cycle costing vs Process continues through post-occupancy vs Source: Roadmap for the Integrated Design Process More decisions made by fewer people Linear process Systems often considered in isolation Limited to constrained optimization Diminished opportunity for synergies Emphasis on up-front costs Typically finished when construction is complete © Climate Resources Exchange (2014) Pte Ltd 14 LEED/Green Mark is not the same thing as an Integrative Design Process Often the team’s only purpose is to achieve LEED points • The architecture is designed separately, without the engineer’s input concerning its energy performance • Energy modeling is done only to get the point, rather than to inform design decisions • Commissioning is often an afterthought • Etc. © Climate Resources Exchange (2014) Pte Ltd 15 Bank of America in NYC – The New Republic Magazine July 28, 2013 “What LEED designers deliver is what most LEED building owners want—namely, green publicity, not energy savings,” John Scofield, a professor of physics at Oberlin, testified before the House last year. Governments, nevertheless, have been happy to rely on LEED rather than design better metrics. Which is why New York’s release of energy data last fall was significant. It provided more public-energy data for a U.S. city than has ever existed. It found the worst-performing buildings use three to five times more energy per square foot than the best ones. It also found that, if the most energy-intensive large buildings were brought up to, the city’s total greenhouse gases could be reduced by 9 percent" the current seventy-fifth percentile © Climate Resources Exchange (2014) Pte Ltd 16 Performance Metrics Importance of Integrative Design Process • Early feedback from engineers informs the design process • Building performance metrics set clear indicators for evaluating competing design solutions • Load reduction measures can be exploited in sizing and selection of equipment (offsetting cost of premium elements) Courtesy of UWCSEA - Simon Thomas © Climate Resources Exchange (2014) Pte Ltd 17 London City Hall “Norman Foster’s City Hall, which is billed as an exemplary sustainable building, uses 50% more energy than it was designed to do.” BREEAM “Excellent” Why?
