Net Zero Energy Use Site Water Balance Materials : Local, Recycled,Renewable Carbon Neutral Transportation Market Recognition (Validation - LEED)Net Zero Energy Goals:

Site Energy Net Zero:All energy consumed at The Brando is generated at The Brando

Source Energy Net Zero:All energy consumed at The Brando isgenerated from renewable energyWater Balance Goals:

Low Energy Water IndependenceLimit reliance on desalination

Protect the Water LensConservative drawdownPrevent ContaminationMaterial Goals:

Utilize local materials

Utilize recycled content materials

Source wood sustainably

Use low toxic emissions materials

Recycle construction wasteCarbon Neutral Transportation Goals: Net zero carbon impact in operational phase

Market Recognition/Validation:LEED Rating System Leadership in Energy and Environmental DesignUS Green Building Council LabelInternational Recognition Point System Guideline to Achieving GoalsSustainable Sites Water Efficiency Energy & Atmosphere Materials and Resources Indoor Environmental Quality 3rd Party Measurement and VerificationCertification based on pre-requisites and credits Silver, Gold, Platinum

Net Zero Energy Methodology:

LEED approved energy simulation program All buildings simulated as designed ResultsProvide profiles of energy loads, andPredict % energy savings Model is not complete; final savings to bedetermined based on design changesThe Brando - Energy Load ProfileProcess Loads ~ 26%(Refrigeration, Cooking, Dishwashing, Exterior Lighting, Cart Charging, Water Treatment, Waste Water Treatment)Building Loads ~ 74%(LEED Regulated)The Brando - Regulated Load ProfileNet Zero Energy Modeling ResultsKwh/SF/YrASHRAE Requirements: -Air barrier -Lighting power -Lighting controls -HVAC controls -Insulation -Glass g-factorNet Zero Energy Modeling ResultsKwh/SF/YrAdditional Design Measures: -SWAC (Sea Water A/C) -Equipment Loads -Natural VentilationNet Zero Energy Modeling ResultsKwh/SF/YrRenewable Sources: -500Kw PV Array -Solar Hot Water(For LEED, SWAC is adesign feature, not a renewable energy)

Net Zero Energy Modeling ResultsKwh/SF/Yr-Energy reduction of 80% of total loads-Achieves all LEED points for energy (15% reduction required)Energy Savings Profile

Net Zero Energy: Closing the GapKwh/SF/YrOptions to reduce final 4.1 load:

Site Net Zero: -Increase PV array > 500Kw -Develop storage system Zinc Bromine Flow Battery -Wave Energy

Source Net Zero: -Bio-fuel generators (coconut oil) -Carbon offsets for transport of fuel to island * *Note: 90% of all coconut oil produced in FP is exported thus transported away using fuelWater Balance Goals:

Material Goals:

Utilize local materials

Utilize recycled content materials

Source wood sustainably

Use low toxic emissions materials

Recycle construction wasteMaterialsRegional Materials Limited island resources Ironwood, non-endemic wood Pandanus Coral, sand aggregate

Recycled Content Palmex roofing Composite decking Cement Iron InsulationRapidly Renewable Materials Pandanus Bamboo flooringComposite Wood Products Urea-formaldehyde free (Carcinogenic, respiratory irritant, allergic reactions) Fiberboard, Particle board, plywoodFSC (Forestry Stewardship Council)certified sustainably harvested andhandled wood for: Structural Framing Flooring Sub-flooring Wood doors Finishes Fixed Furniture

Volatile Organic Compounds (VOCs) Sealants, paints, primers, adhesives Limits and threshold compliance Contribute to excessive ground ozone Cause smog, crop destruction, respiratory ailmentsConstruction Waste Management

Divert from landfill through recycling or reuse 50% of waste from:

Concrete/Masonry Carboard Plastics Metals Wood

Carbon Neutral Transportation Goals: Net zero carbon impact in operational phase

Account for travel related emissions GuestsStaffGoods / Fuel / Materials / WasteBrando Boundary OptionsBoundary 1: All carbon associated with travel on the island

Boundary 2: Transportation from Tahiti to The Brando

Boundary 3: International transportation to TahitiBoundary 1: Tetiaroa

Bikes provided for all guests All motorized vehicles are electric

Boundary 2: Tahiti

Docks and airport within 500m of public transport Shuttle to Air Tetiaroa from ICT international terminal Staff incentives for using public transportation Carbon-offset purchase for inter-island transport

Boundary 3: International

Guest option to purchase carbon offsetsIssues Encountered in Sustainable Goals Tight insulated envelope vs traditional breathable designRisk of humidity damageCost/benefit of insulation with low marginal cost of SWACMay encourage more AC use

Window designSolar gain and conductivity loss vs light energy savings

Closing the water loop Effluent to potable Administrative opposition Rationale of roof rain water capture (lens reservoir)

Difficulty and cost of closing energy gapTransportation and boundary definition are key

Limits to going green in remote island locationsLocal recycling capabilityAvailability of reused, recycled or local materialsPolitics (pandanus monopoly), availability
