3 The Evolution of CIRS ,500 m 2 UBCV $18M ,000 m 2 GNWC $50M ,000 m 2 GNWC $36M ,000+4,000 m 2 GNWC $55M ,600 m 2 UBCV $38M

4 Building as research instrument

5 From less bad to more good From reducing damage to creating benefits From sacrifice to contribution From net zero to net positive

6 Green Design Goals Design with time in mind (CC and LCA) Zero materials waste Ecological health (energy, water, biomass) Humane Inhabitant comfort Outstanding IEQ Connections Occupants to inhabitants Smart Instrumentation and controls Replicable and economical solutions

7 Regenerative in Environmental Terms Net positive on: Energy Operational carbon Water quality Structural carbon

8 Energy Balance - Summary -860 MWh nat. gas -154 t CO2e = MWh 990 MWh UBC Steam Plant = 275 MWh Net positive energy use EOS 600 MWh CIRS 306 MWh 585 MWh elec.

10 Regenerative in Human Terms Occupant Passive recipient of building systems Sustainability Charter Suite of Benefits and Opportunities Inhabitant Engaged, with a sense of place Metrics: productivity, health and happiness

11 CIRS Inhabitant Benefits/Opportunities 1. air quality and natural ventilation 2. acoustic performance 3. natural daylight 4. operable windows 5. web-based lighting controls 6. wood frame & green roof 7. Sustainable café & social meeting spaces 8. VDI environment 9. real-time building performance data 10.information and discussion forums 11.participation in building mgmt strategies

12 3,000 points of monitoring (excluding F/A) Total electricity Electrical panels (including plug loads) Solar PV Solar hot water Domestic water supply Rainwater harvesting Reclaim water Storm-water redirected to aquifer Available day-light Indoor CO2 and VOC Weather-related (RH; CO2; air temp) Space controls (radiators; air temp) Window status and controls F/A Digital video monitors

13 Construction Cost (million 2011 dollars) Capital Cost of Comparable UBC Buildings $80 $60 $40 UBC comparable buildings CIRS $20 $ Floor Area (000 sq.ft)

14 CDN$ NPV 2011 Millions of 2011 $ 25 YR NPV Total Cost of Ownership CIRS vs. minimum standard Capital Renewal Operating Costs Construction Cost (2011) 0 Best Practice (LEED Gold) Beyond Best Practice (CIRS)

15 Environmental and Human Performance Environmental performance Considerable work on performance measurement Not yet achieving net positive outcomes in energy, water or carbon Human Performance PREOE being written up; POE being designed Programming not yet in place

16 Community Impacts: UBC as a Living Lab for Sustainability

17 Regenerative Sustainability Lens and Gradient PLANNING DESIGN CONSTRUCTION COMMISSIONING OPERATION Proforma User Needs Design Brief Design Build Commission Occupy Operate/ Inhabit Technical Guidelines Programming IDP Sustainability Targets Tools e.g.: LCA LCC BIM Rating Systems IPD Construction Mgmt. Tools Asset Mgmt. Tool BPE Inhabitant Engagement Standard Process New Tools/Processes (Lens)

18 Building Lifecycle Integrated Design Process (IDP) D Continuous Optimization O Integration C Lean & Green Construction C Lifecycle Planning

19 The CIRS Research Program Sustainable buildings design and operations Community engagement and social action Regenerative sustainability beyond the building scale

20 Sustainable Building Evaluation quantitative Building modeling Performance measurement Pre- Post- Pre- Occupancy Evaluation Post- Occupancy Evaluation qualitative

21 Proper Disposal (%) Ratings of Environmental Consciousness Recycling Behaviour in CIRS SUB Location CIRS 1 General SUB CIRS Location

22 BC Hydro Theatre Exploration Telepresence Immersion Collaboration Immersion

23 How to get from this to this High carbon world Low carbon world

24 Conclusions Net positive building design and implementation is possible Considerable implementation challenges Human side harder to get established

25 Background Slides

26 A Regenerative Building Process All water from the sky All liquid waste treated on site All heating and cooling from the ground/neighbours/sun All light (when avail.) from the sun Green electricity (25 kw PV) Natural/displacement ventilation Wood building Continuous net positive research: on water quality technical performance of net building positive systems on energy and GHG emissions behavioural interface of building net positive & inhabitants on structural carbon
