Transcription

1 CODE INNOVATIONS FOR LIVING BUILDINGS: BRIDGING THE GAP CHRIS VAN DAALEN PRINCIPAL INVESTIGATOR THE CODE INNOVATIONS DATABASE ANDREW LEE SUSTAINABILITY CONSULTANT + CO-CHAIR CASCADIA GREEN BUILDING COUNCIL, SEATTLE COLLABORATIVE

2 INNOVATORS: R&D FOR LIVING BUILDINGS Develop new designs, materials & technology Pioneer new compliance paths Drives evolution of Building Codes

3 INNOVATORS: PUSHING THE ENVELOPE Beyond LEED and Built Green Living Building Challenge Passive House Standard Net-Zero Energy, Net-Zero Water Architecture 2030 Challenge

4 Regulatory Disconnects Code Barriers to Living Buildings can slow or stop a project How do we bridge the gap?

5 MAKING IT EASIER TO BUILD GREEN

6 CASCADIA SEATTLE COLLABORATIVE Advocacy Tools living-future.org/node/1629 living-future.org/research

7 PURPOSE OF BUILDING CODES Safeguard public health, safety and general welfare from hazards attributed to the built environment 20th Century Risks: It works!

8 HOW WILL CODES EVOLVE? New hazards have emerged How will codes evolve to address new risks?

9 BUILDING CODES ARE EVOLVING Balancing ALL the Risks Driven by: Policy Voluntary Certification Programs Innovations Leading the Industry

10 WHAT S THE GOAL? Source: Living Building Challenge 3.0, ILFI, 2014.

11 HOW DO CODES EVOLVE? 1. Incremental change driven by policy minimum increase each 3-year code cycle 1. Next gen codes driven by voluntary adoption stretch codes/certifications test future code 1. Code innovation driven by industry leaders break rules and pioneer structural changes

20 ENERGY CODE COMPLIANCE OPTIONS Prescriptive Component-based requirements for efficient envelope and systems Modeled Predicted energy savings based on the comparison of a whole-building energy model to a relative baseline

21 ENERGY CODE COMPLIANCE OPTIONS Prescriptive Component-based requirements for efficient envelope and systems Modeled Outcome-Based Demonstration of actual performance based on measured results of completed building Predicted energy savings based on the comparison of a whole-building energy model to a relative baseline

22 EXAMPLE - ENERGY CODES Supply Laundry Deep Energy Retrofit Outcome based compliance Pilot in Seattle Now in IGCC What s next?

23 STORMWATER CODES Policy: Clean Water Act - National Pollutant Discharge Elimination System (NPDES) WA Dept. of Ecology Permits Local code updates Low-Impact Development & Green Stormwater Infrastructure

24 EXAMPLE - STORMWATER CODES Clearwater Commons Positive Impact Development First voluntary LID path 16-unit development combined habitat restoration, permeable paving, infiltration and.. Pin Foundations - zero soil-disturbing

25 HOW DO CODES CHANGE? Tomorrow s codes driven by Innovation Industry Leading Programs Living Building Challenge Net Zero Passive House Standard Architecture 2030

36 THE CODE INNOVATIONS DATABASE A new web-based resource to help building officials, builders and other stakeholders to share information about successfully permitted green and high performance building innovations. Making it Easier to Build Green!

37 Bridging the Gap Find successful precedents Prevent reinventing the wheel Learn through collaboration Use info to advocate at multiple levels

38 ADAPT IN A CHANGING ENVIRONMENT Use the database Innovate more efficiently Builders save time & money Code officials job gets easier Help meet your Sustainability Goals: more green projects designed and permitted more sustainable, energy-efficient projects built and retrofit more affordable, accessible to more people

39 Regional Expansion Strategy: Put actionable permitting precedents into the hands of Every Code Official in the Northwest Publish hundreds more case studies of successful innovative projects Add profiles on adopted green codes, incentives and compliance initiatives Advocate & Educate for policy innovation
