2 Why Change? Do we really need to have this conversation? Residential & Commercial Buildings Drivers of Climate Change Everything Else (industry, travel, agriculture etc )

3 Proactive or Reactive It s our choice

4 What will YOU do? It s our choice???????????

5 We have no choice From a 2012 Presentation National Legislation Investing in value instead of energy consumption requires little financial efforts but rather creativity and intelligent solutions ~ Wolfgang Feist

6 Design & Construction Broken process Lack of integration Lack of respect Lack of basic physics Lack of a useful feedback mechanism Lack of components Define the Problem The first step in solving a problem Forget everything you know and walk in backwards ~ Katrin Klingenberg

7 What do we need to do? Broken Create aprocess better process Lack Create ofaintegration system for integration Lack Foster ofan respect atmosphere respect, humility and understanding Lack Educate of basic and inform physicsthe profession in basic physics Lack Design of anda useful install feedback useful feedback mechanism mechanisms Lack Create, of components test, refine and market components

8 What do we need to do? Create a better process

9 Create a better process Integrate design & construction

10 What do we need to do? Integrate design & construction Create a system for integration

11 Program, Use & occupancy Site Form Structure MEP systems Process energy Cost Create a system for integration Understand the Process and Integrate Client Architect General Contractor Operations & Maintenance Personnel Financier MEP Engineers Sub- Contractors Users Energy Modeler Civil Engineer Landscape Architect Structural Engineer

12 Create a system for integration Integrated information flow leads to Fiscal Control Design effort / effect 1 Ability to impact cost & function Cost of design changes Predesign Schematic Design Design Development Construction Documents Bidding Construction

15 What do we need to do? Foster an atmosphere respect, humility and understanding

16 Foster an atmosphere respect, humility and understanding Project Roles Motivations differ Owner / Client Architect CPHC Builder Engineers Building Officials Bank Project development starts with Understanding Material use Longevity Stewardship Experimentation Economics Technology Philosophy Energy Just because I can Low impact

17 Foster an atmosphere respect, humility and understanding Process is not bid based but objective driven OPD & BOD separation Assumes a siloed process in which each discipline is contracted to perform in their area of expertise. The outcome of the project is not a jointly held responsibility, but rather an orchestrated process in which some entity, commonly the architect, construction manager or owner s representative takes on the role of chief cat herder. Job Description: Attempt to facilitate and coordinate each discipline s additive portion of the design to achieve a well performing and cost effective high performance solution. The outcome is sometimes achieved, very often the outcome is less then optimal creating either expensive solutions or cost effective projects with energy savings, comfort and air quality left on the table.

18 Foster an atmosphere respect, humility and understanding Changing the way we do business Statement of Project Objectives (SPO): A single document that is performance based. It starts with the business case or cost proforma of the project. To this the functional, aesthetic and performance metrics are added. There is no BOD document. Why?? When we are orchestrating IPD and/or utilizing a relational contract, we want to employ the lean technique of pull production or the last planner approach. We do this not only in the construction of the project but also in the design of the project. We want all possible solutions on the table for all aspects of the project until the last possible moment where we can decide as an informed group which set of options produced the optimized solution for budget, function, aesthetic and performance.

19 Foster an atmosphere respect, humility and understanding Changing the way we do business TEASER MEET Me tomorrow 9am to discuss the THREE LEVELS of LEAN

20 What do we need to do? Educate and inform the profession in basic physics

21 Educate and inform the profession in basic physics Knowledge should be a freely shared resource Teaching Mentoring Lecturing

22 What do we need to do? Design and install useful feedback mechanisms

23 Design and install useful feedback mechanisms Not just hardware and software Smart systems that alert users to deviation Management by exception Feedback mechanisms in systems design & analysis Lean tools

24 What do we need to do? Create, test, refine and market components

25 Craft Solutions Eliminate non-value added work Envision the product properties The product will seek to create and leverage efficiencies in design, manufacturing and construction to create a market rate product as part of a solution for high performance construction in sector being served. Design The product will allow designers flexibility but will allow designer to trade flexibility for reliable cost savings, quality control, ease of detailing, ease of energy modeling, robust durability Manufacturing The product will embrace a lean standardized approach with minimized shop drawing, automated parts creation, single point entry, efficiency in factory motion Construction The product will be intuitive to North American trades, consolidate or eliminate site labor, create simple solutions to complex issues

26 Design Allows designers flexibility, constrains flexibility for reliable cost, quality control, ease of detailing, ease of energy modeling, robust durability Standard System Think Lego Design Flexibility Ease of Detailing Quality Control Robust & Durable Reliable Cost Easy Energy Models
