DND approach to green buildings
• Realty: a sustainability opportunity • Policies & motivators • DND Unique challenges & considerations• DND Strategy for green building• Tools• How are we doing• Future direction
realty: a target of opportunity for DND transition to sustainability • strategic context • life cycle cost savings • productivity& QOL enhancements • Reduced impacts, residual liabilities• Kyoto commitments• Demonstrate stewardship
DND Approach to Green Buildings
Policy and motivators
Policy: Defence Sustainable Development Strategy (SDS)
• Minister’s commitment• policy fostering sustainability • 1997 realty objectives, targets, action plans • 2000 “integrating” environment into realty
“decision-making” “processes & practices”• 2003 (planned): first “green building target” • Reporting: whole building environmental
assessment
Policy: Defence Sustainable Development Strategy (SDS)
• regulatory compliance • due diligence/ environmental risk management• policy integration/ dissemination/ implementation• stewardship/ acculturation • environmental Management System (EMS)• green procurement• issue targets, action plans

Fraser slams military over poor SDS implementationby the muck raking journalist of your choice
The Canadian Forces need to do a better job implementing their SDS policy in the delivery of the construction programme says the Auditor General Sheila Fraser. The DND responded to the auditor’s report…

DND Approach to Green Buildings
Unique challenges and considerations
DND realty sustainability challenges:
• custodial “life cycle” asset management • unique DND realty context:
environmental issues: range/ complexity/ risksasset age/ campus contextcapacity for re-capitalization diversity of occupancies spanning climatic regionslimited knowledge/ capacity
• Priority: existing buildings
DND realty: sustainability challenges:
• all pre-design, design & construction: contracted• facilities management: contracted/ alternate
service delivery • monitoring & oversight of 3rd party providers• Render transparency/ measurability/ sustain
documentation• transferability of lessons learned to portfolio
DND Approach to green buildings
Elements of Green Building Strategy
DND Green Building Strategy
• collaboratively developed • lessons learned• conceived as continuum • coordinated with SDS cycle/ updated annually • commercially available whole building assessment• integrate decision support tools/ modeling• synergies with other initiatives/ programs • foster knowledge transfer/ capacity building
DND Green Building Strategy: 1. Existing buildings
• Existing buildings: whole building assessments – for benchmarking – post occupancy evaluations – due diligence;– to assess/ improve operations – target remedial work for re-fit & renovations– lessons learned
• Initiated: on-line assessments by base staff
DND Green building Strategy2. existing buildings retrofit
• energy performance contracts under FBI• utility data management • building energy performance indices
(BEPI’s) for building archetypes• BEPI’s: feed into existing building
assessments• On-line retrofit assessment tool planned
DND Green Building Strategy:3. New building project delivery
• adaptation of “Green Leaf” to support “environmental issues integration” into each stage of ISO 9001 “project delivery” process
• partnership with PWGSC • (alpha) on-line version: “Green Globes for
new buildings” (DND) Testing/ translation • support to SDS 2003 green building target
DND Green Building Strategy 4. targeted issues/ savings
Example: operating energy/ GHG reduction • strategic: : target 10% • operational savings: : estimate > 10%• retrofit existing buildings: 20% per EPC
benchmark archetypes• New building min 25% less than MNECB:
substantiation: CBIP modeling
DND Green building approach
Assessment & decision support
TOOLS
Tools: DND/ PWGSC environmental integration framework
• Structured: whole building environmental assessment
• Contextual: issues/ goals relevant to DND • Targeted: guidance/ indicators of content/ specificity
targeted for “each” stage• Integrated: decision support/ modeling/ compliance • Transparent: Checklist/ indicators at “each” stage
• Measurable: rating at major milestones • Flexible: generic framework with add-on modules
Tools: DND/ PWGSC on-line Green Globes for new buildings
• “DND/ PWGSC environmental issues integration framework” On-line
• available alpha test version www.greenglobes.com/nbalpha/ DND version
• DND variant identical to general practitioner except hotlinks to Federal regulations, policies
• synergies with other Federal programs• seamless input to CBIP energy modeling • links: decision support tools

Questionnaire Screen
Other than entering the CBIP input information, most questions are “yes” or “no”.
TOOLS: DECISION SUPPORT ATHENADESIGN LCA MATERIALS
Tools: Value-based selection including “sustainability”
• Design-build: evaluated 50% price/ 50% “quality”• “quality” points include “Sustainability” • detailed CBIP energy simulation • min perf: 25% below MNECB• Price: annual energy cost x 10 + (capital cost) • encourage 10 year payback energy saving features• 15 sustainability points: LEED substantiation

The Officers’ Accommodation and Mess Facility is a 9100 m2, 5-storeycomplex, located on the Canadian Forces Base (CFB) in Esquimalt,Victoria. The complex consists of 140 officers’ cabins, two lounges, diningroom, and miscellaneous support space. The complex was occupied in thespring of 2000 and procured through design-build delivery. The buildingcomplex is owned by the Department of Defence, and is managed by BaseConstruction Engineering Office. Capt. L. P. Oakes is the FacilitiesSupport Officer

DND Green Globes development/ adaptations
• occupancy & environmental issue specific add on’s
• jurisdictional overlay “existing buildings”• Foster retrofit transition to Green building
performance contracting (GBPC) from EPC • Retrofit version to support GBPC• Provincial/ municipal jurisdictional
overlays?
LEED CanadaFederal jurisdiction adaptation
• statutes, regulations, policy & standards applicable to Federal jurisdiction
• reconcile credits with Federal procurement policy & trade agreements
• Rationalize regional/ climatic applicability• foster balanced approach • heritage, physical security, maintainability
Conclusions
• whole portfolio view/ each phase of activity• Acculturation- Process modification- strategy-
best practices • Timely feedback/ lessons learned/ transferred• Capacity building• Hierarchy of tools/ same concepts/ different
packaging• What works for you • Reward/ recognition
