3 GREEN BUILDING Terramanzi Environmental Consulting

4 WHAT IS A GREEN BUILDING Green building incorporates design, construction and operational practices that significantly reduce or eliminate the negative impact of development on the environment and people. Green buildings are energy efficient, resource efficient and environmentally responsible. Green Building Council of South Africa

5 IMPACT OF THE CONSTRUCTION INDUSTRY 39% 70% 40% 40% total energy electricity CO2 emissions material consumption 65% 12% 25% 50% municipal solid waste water timber harvest Ozone-depleting CFC s In South Africa, operation of the building sector accounts for approximately 23% of greenhouse gas emissions

6 MEMBER OF WORLD GBC MISSION: The Green Building Council of South Africa will lead the transformation of the South African property industry to ensure that all buildings are designed, built and operated in an environmentally sustainable way that will allow South Africans to work and live in healthy, efficient and productive environments VISION: To promote, encourage and facilitate green building in the South African property and construction industry through market-based solutions, by: Promoting the practice of green building in the commercial property industry Facilitating the implementation of green building practice by acting as a resource centre, Enabling the objective measurement of green building practices by developing and operating a green building rating system, and Improving the knowledge and skills base of green building in the industry by enabling and offering training and education

7 GREEN BUILDING COUNCIL OF SOUTH AFRICA The Green Star SA system is: Comprehensive rating system for evaluating the environmental design and performance of South African buildings. The system validates the environmental initiatives of new commercial office buildings or base building commercial office refurbishments (DESIGN or AS BUILT ratings available). Criteria include energy, materials and water efficiency, indoor environment quality and resource conservation. The SA system has built on existing systems and tools including the Australian Green Star, the British BREEAM system and the north American LEED system.

8 GOALS OF THE RATING SYSTEM Set benchmarks and standards of measurement through Establishing a common language for green building (e.g. no greenwash ) Promote integrated, whole-building design Recognise environmental leadership Raise awareness of green building benefits Reduce the environmental impact of development Green Star SA is not a design guide provides a framework for creative interaction and synergy between a multi-disciplinary team

10 C&D WASTE MANAGEMENT Terramanzi Environmental Consulting

11 CONSTRUCTION WASTE MANAGEMENT This credit encourages and recognizes management practices that minimize the amount of construction waste going to disposal (includes demolitions and construction phase). Points are awarded for the Contractor implementing a Waste Management Plan (WMP) which must describe how waste is monitored, which type of waste will be collected for recycling or for reuse, and who is responsible for aspects of the plan. This WMP must be implemented prior to construction commencing. The Contractor will need to retain waste records and issue quarterly reports to the building owner. Projects are awarded according to the percentage (%) by mass of demolition and construction waste which is reused or recycled.

12 CONSTRUCTION WASTE MANAGEMENT

13 TYPICAL MATERIALS Bricks and concrete used for clean-fill Timber salvaged for new structural or material use; timber waste ground into mulch or compost Crushed concrete used for road-base Plasterboard crushed for soil conditioner or manufacture of new plasterboard Steel, aluminum and other metals for reuse in the manufacture of new metal products Foam insulation and packaging for new insulation or soft structural forms Pallets for reuse Clean plastic for packaging new packaging materials Carpet and ceiling tiles may be taken back for reconditioning/recycling by the manufacturer Light fixtures for cleaning and reuse Furniture for refurbishing and reuse Crushed tiles for paving or landscape decoration

14 CASE STUDY Terramanzi Environmental Consulting

15 DEMOLITIONS WASTE MANAGEMENT STAGE 1: SOFT STRIP WASTE This stage typically comprises approximately 4% of total waste that is produced during the demolition stage of a demolitions Project and will disposed of at a Licensed Municipal Landfill operation such as Strandfontein Coastal Park and/ or Vissershok. The following wastes are typically recovered in Stage 1: Plastics Boards Timber Caulking

16 DEMOLITIONS WASTE MANAGEMENT STAGE 2: HARD STRIP WASTE This waste is typically valuable waste and is reused for second hand resale at Second Hand Store or alternatively transported to 5 th Avenue Recycling Area in Parow, Cape Town. The following wastes are typically recovered in Stage 2: Window Frames Metal piping and conduits Doors Electrical wiring and cables Fluorescent light ballasts Steel and metals

17 DEMOLITIONS WASTE MANAGEMENT STAGE 3 CRUSHING All wastes in this stage can be crushed (such as concrete floors, ceilings and walls) which are crushed to an aggregate of less than 25mm in diameter. This aggregate is sold to Corobrick, which in turns produces bricks from this material. The following wastes are typically recovered in Stage 3: Walls Ceiling panels Concrete

28 CASE STUDY

29 BUILDING REUSE Terramanzi Environmental Consulting

30 BUILDING REUSE Reuse of buildings and parts of buildings can significantly reduce the demand for new construction materials and reduce the environmental impact from development. Points are awarded where a proportion of the total existing façade of the building is reused (either by 60% OR 90%) Points are also awarded where a proportion of the major structure, by gross building volume is reused (either 30%, 60% or 90%). This credit addresses the retaining of existing materials, not the final design, and so it is irrelevant whether the retained materials are refurbished with additional material. The allocation of points for reuse of structure is based on gross building volume and not material volume.

31 BUILDING WITH RECYCLED MATERIALS Terramanzi Environmental Consulting

32 MATERIALS Incorporating recycled products into buildings help reduce reliance on virgin materials, and creates a market for recycled materials. Many products containing a recycled component requires significantly less energy to manufacture, reducing the embodied energy of the product Reusing products and materials is a definite approach towards ensuring that the useful life of products is extended and diverted from landfill. Points are awarded where the materials that are selected for base building construction have a recycled content or are reused items for a percentage of the total contract value (0.5% or 1.0%) It excludes steel, timber, concrete mix components and masonry units Only materials permanently installed on the project site are eligible. Examples of reused materials include windows, cladding, flooring, doors, sanitary and lighting fixtures/fittings. Examples of recycled content include insulation, aluminum, glazing, gypsum, flooring, carpets, facades and roofing materials.

33 CONCRETE Reinforced concrete can readily utilize both the post-consumer and postindustrial waste, thus reducing waste, consumption of natural resources and greenhouse gas emissions. Replacing a portion of the Portland cement with industrial by-products such as fly ash, blast furnace slag and silica fume reduces the mining of natural resources and greenhouse gas emissions associated with cement production while disposing of a waste material previously destined for landfill. This credit encourages and recognizes the reduction of embodied energy and resource depletion occurring through the use of concrete. Points are awarded where the project has reduced the absolute quantity of Portland cement by a minimum percentage, by substituting it with industrial waste product(s) or oversized aggregates (30% or 40% reduction). Additional points are awarded where 10% of the aggregate used for structural purposes is either recycled or slag.

34 STEEL This credit encourages and recognizes the reduction in embodied energy and resource depletion associated with reduced use of virgin steel. Points are awarded depending on whether the building is predominantly structural steel or predominantly reinforced concrete or structural masonry. It rewards projects on the percentage (%) of average post-consumer recycled content of the structural steel and whether the structural steel is reused. Steel applications for structure types include: Predominantly structural steel building: hot rolled beams, columns, angles, hollow sections, parallel flange channels, mullions, purlins, girts and light steel framing systems Predominantly reinforced concrete or structural masonry building: reinforcing bar, reinforcing mesh and permanent steel formwork. Major Steel applications in the building include: Structural steel applications Building envelope steel applications (wall cladding and profile roof decking)

35 TIMBER This credit encourages and recognizes the specification of reused timber products or timber that has certified environmentally-responsible forest management practices. Expected timber uses within the credit include: Structural timber including wall, floor and roof structure External and internal cladding Flooring/wall/ceiling finishes Internal and external joinery including windows, doors and other specialist uses of timber such as installed furnishings, joinery fixtures or balustrades Structural formwork Points are awarded where a minimum percentage (%) of all timber and timber composite products used in the building and construction works are compliant with sourcing requirements (FSC certification scheme) Compliant timber and timber composite products must be: Reused timber Post consumer recycled timber Forest Stewardship Council (FSC) certified timber

36 MASONRY Through introducing higher levels of perforations into clay masonry units, the mass of the units is reduced which has a direct impact on energy processes of manufacturing. Reducing the mass of a masonry unit also impacts on haulage, with lighter loads and reduced transport. Points are awarded where a minimum percentage (%) by area of masonry units has used one of the following strategies (50% or 80% area) For Clay bricks, perforated or reused masonry units are used For Concrete bricks, perforated or recycled content masonry units are used For Concrete blocks, recycled content masonry units are used Applicable masonry units include those for walling (structural and nonstructural) only Demonstration of compliance is based on area ( face or elevation area)
