Green Vision• water efficiency
• sustainable site selection
• raw materials that support resource conservation and sustainability
• indoor air quality
Green Vision (contd)• integration of
biological diversity (green spaces)
• community living
• energy efficiency in materials and design
Green Vision (contd)• reduce role of
private vehicle• building
infrastructure for pedestrian an cyclists
• improve public transit
• using existing vehicular infrastructure
Green Vision (contd)• introduction of
mode switching
• implementing vehicle emission standards
• integrating transport and overall planning policies
Green Vision (contd)• integrated
disaster risk and climate change adaptation
Barbados Green Building VisionEconomic Social EnvironmentalSupply and use of energy efficient building materials
Redesign of community living; building homes and communities not houses and developments
Reduced footprint on land (building upwards, space efficient)
Economic building practices Places instead of spaces High-tech recycling systemsShift from wood to more plastic in construction
Greening our way of life by educating stakeholders
Use of reusable materials
Efficient building design More green spaces Use of natural ventilation; climate specific design
Fully integrated cadastre system Cultural shift towards more communal living
Energy efficiency with land, sea, sun and wind turbines generating energy for street lights, homes and other buildings Fully motioned sensored lights for neighbourhoodsStreamlined, computerised, energy efficient, interactive, prefabricated, mass produced buildings Application of smart technologies across home systems
Challenges to Green Urban
•relatively high costs of newer technologies•absence of an overarching policy framework• lack of training programmes•Barbados Building Code not yet operationalised•lack of standards for building contractors•over reliance on fossil fuel•chronic traffic congestion•unsustainable annual growth rates•no national standards for air and noise emissions•poorly integrated public transport services•constraints on financial and human resource capacities•public perceptions of green initiatives and cultural preferences
Enabling Environment:
• Supporting legislation and regulations
• Policies and programmes
• Demonstration projects
Opportunities:
• Social housing policies
• Caribbean raw materials
• Smart technologies
Social Housing Policy
Opportunities include:• refinement /development of underlying
principles, policies and standards for green housing
• introduction and training towards green building certification e.g. LEED
• promotion of private – public sector green community demonstration projects e.g. Eckstein Village
Social Housing Policy
Opportunities (Contd):• revision of green building guidelines
based on experiences with pilot projects
• community sensitisation, participation and ownership of green building outcomes
• approval of the Barbados Building Act and operationalisation of the Barbados Building Standards Authority
Social Housing Policy
Opportunities (Contd)• adoption of the Barbados Building
Code 1993, update with standards for green building
• approval of the Water Reuse Act and establishment of standards for grey water use
• refinement of solid waste management policies to promote waste reduction and sorting at the household level

Caribbean Raw Materials
Construction raw materials include:• Cement and concrete blocks• Wood• Clay
Smart Technologies
A central system to control the home environment – heating, lighting, security
Summary• Enormous
potential for move towards the required integrated approach for green economy
• A highly participatory process is required
