1 Green Recovery And Reconstruction: Training Toolkit For Humanitarian Aid Construction Session 2: Sustainable Construction Design Fundamentals

2 2 Mod 6 Ses 2 In this session we will discuss… Key challenges of sustainable construction The concept of the Green Baton The importance and value of several fundamental sustainable construction design concepts How to use these fundamental design concepts to analyze and recommend solutions to several sustainable construction case study challenges

3 3 Mod 6 Ses 2 Key Challenges Lack of understanding of ecological impact of construction activities Lack of early rapid environmental assessment Use of hazardous materials Special interests who dont prioritize sustainable construction Disregard for the local population Poor planning by project managers Others? How is sustainable construction impacted by these challenges? (write 1 challenge per card)

4 4 Mod 6 Ses 2 The Green Baton Concept More Sustainable BriefingDesign Detail Design Prodn Info Tender Action Site Options Handover And O + M Client Design TeamContractor Affected Population The Green Baton may be dropped at key points in the process…Once dropped, it is difficult to pick up again and regain lost ground. Howard Liddell Less Sustainable

5 5 Mod 6 Ses 2 Picking Up the Baton What experience do you have for the baton being dropped? When & How? What might be the reasons at different stages of construction that some stakeholders may drop the green baton? How can we pick up the baton? Or not let it fall? What actions are needed at different stages taken by different stakeholders?

6 6 Mod 6 Ses 2 Design Challenges & Solutions Choice of Materials The choice of materials can impact the host community, the environment and future maintenance needs... How?

7 7 Mod 6 Ses 2 Impacts of Material Choices The project manager must weigh the potential impacts at each stage Extraction, mining, harvesting Processing and production Transportation & distribution Packaging Building Disposal Environmental impact?

8 8 Mod 6 Ses 2 Design Challenges & Solutions Use of Existing Materials With this workshop, on the topic of construction, we go deeper and discuss Reduce Reuse Recycle Refuse (to build) Repair Recover (energy) In the workshop Materials and the Supply Chain we discussed the 3-Rs: Reduce, Reuse, Recycle

9 9 Mod 6 Ses 2 Ore, stone, clay, Oil, timber, plants, etc. Metals, chemicals, cement, fired Clay, fibre, sawn timber, etc. Building Structural materials, climatic materials, surface materials Waste Primary refining process Secondary refining process Building process Mining, Drilling, harvesting DumpingUse Ore Oil Timber The Earth Berges Cycle of Materials RecycleReuse

10 10 Mod 6 Ses 2 Support legal and sustainable practices Minimize packaging in procurement of materials Purchase materials locally when practical Do no harm concept: environmental and economic impact Design Challenges & Solutions Sourcing & Procurement 10

11 11 Mod 6 Ses 2 Challenge vs. Solution Illegally cut lumber in BrazilWood certified as harvested responsibly

12 12 Mod 6 Ses 2 Design Challenges & Solutions Energy & Climate Concerns Solar orientation Energy efficiency, insulation, ventilation, etc. Climate type: hot/dry, hot/humid, or cold

15 15 Mod 6 Ses 2 Design Challenges & Solutions Getting local community acceptance Community participation Knowledge sharing Analysis of existing, traditional practices Photo by David Gazashvili, CARE Intl

16 16 Mod 6 Ses 2 Design Challenges & Solutions Existing, traditional practices Traditional construction techniques Use local skills & materials; can be implemented faster, to higher standard Space use norms defined by culture & function; can dictate use of building: fully used, partially used, sold, or abandoned External space use norms should be considered (e.g. outdoor cooking in hot dry climates Religious, other beliefs can affect construction (e.g. direction a building and/or its entrances must face)

17 17 Mod 6 Ses 2 Design Failure vs. Success This proposed shelter is said to be earth-friendly, non-toxic and can be assembled easily and quickly in disaster area. BUT, it doesnt meet basic human needs. School built in Maldives after tsunami content/uploads/2008/02/42cdb3panel3_1.jpg
