DESIGN FOR DECONSTRUCTION

the way forward for SUSTAINABLE CONSTRUCTION & DEMOLITION

WHAT DO WE MEAN BY SUSTAINABLE CONSTRUCTION?

 Efficient use of resources  Effective use of materials  Carbon footprint reduction  reduced construction times  Greater use of secondary materials  Minimising waste  Minimising environmental impact  Green thinking

WHAT DO WE MEAN BY SUSTAINABLE DEMOLITION?

 Minimising waste  Creating re-use opportunities  Cutting operational costs by leaner actions  Maximising resource opportunities  Creating and Consolidating markets  Changing perceptions and mindsets  Better planning  Reducing environmental impacts

WHAT ARE THE BARRIERS TO SUSTAINABLE CONSTRUCTION?

 Depletion of natural resources  Bespoke and one off construction types  Conflict with the natural world ecology, flora fauna  Hazardous substance/material usage  Excessive energy or carbon usage  High waste count  Build costs  Perception, mindset and habit

WHAT ARE THE BARRIERS TO SUSTAINABLE DEMOLITION?

 Excessive waste  High cost of waste disposal  Diminishing disposal routes and facilities for waste  Poor construction material and product design  Innovative new build (without green thinking)  Spiralling operational costs  An older workforce  Punitive and outmoded legislation

WHAT CAN DESIGNERS AND PRODUCT MANUFACTURES DO?

 Develop and specify recyclable materials  Introduce green thinking into design  Produce a reusable component or one that is recyclable at worst case  Talk to the demolition industry  Influence clients  Develop take back schemes and or product codes/tags  Innovate to ease deconstruction processes

WHERE DOES THE DEMOLITION SECTOR FIT IN

 Demolition contractors are effectively waste handlers  Accident rates appear to be increasing  Cost of plant and equipment is increasing  The act of demolition is increasingly scientific in its method  Contractors are extremely successful recyclers  The sector suffers from inadequate legislation and regulation  The construction sector has a negative influence

WHAT DO WE NEED FOR THE FUTURE?

 Development of BIM to incorporate DIM  End of life building regulation? Or take the initiative ourselves  Stop use of hazardous materials and products  Put infrastructure into place ahead of legislation  Complete ‘buy in’ to dfd by all parties  Increase number of waste disposal facilities 30 to 60 years problem  Update and innovate planning laws  Change peoples perceptions and goals
