1 Last Issue Date: 26 February 2014 Green Star SA - Rating Tool Innovation Register Important Note to Registered Projects regarding this register: This innovation register of innovation points and denied has been drawn up by the Green Council South Africa (GBSCA) and is intended for use by project teams, contractors and interested parties for information purposes only. Please note that the initiatives listed below have been / denied for innovation points based on the specific circumstances on each project, as well as the manner that these circumstances have been presented to the GBCSA for assessment. The GBCSA in no way guarantees that where initiatives have been in the past, these will be again for future projects. Each innovation submission is reviewed in the context of the specific project and documentation submitted. Any single initiative will only be to three projects under the same rating tool before no longer being for innovation points under the Green Star SA rating tool for buildings of that type - i.e. where on the table below you see under the column ' ' that it is the 3rd time that it has been for a building type, the same type of initiative will not be able to achieve points in the same building type. Where the number for a type of Education Facility / Opportunity in or about the Education Facility: The building has been designed with educational features highlighting the sustainability initiatives employed. A large number of persons will be exposed to the building via a guided tour, and large information boards and plaques are situated in the building to provide information on the green initiatives incorporated into the building's design. Education Facility: This guided tour will be offered on a weekly basis and undertaken by an employee with a thorough understanding of the building's green building initiatives. Permanent displays and information signage highlighting the green features within the building will be installed to impart knowledge about the building to users and visitors. Industrial theatre and E-bulletin: This initiative proposes to incorporate industrial theatre and monthly E-bulletins as part of a broader building occupant training program as a means of inspiring cultural and social behavioural changes within building occupants. Inn As The GBCSA notes that this initiative will facilitate increased market transformation of the South African property and construction sectors. The GBCSA notes that this initiative will facilitate increased understanding of the green building industry. The GBCSA believes that whilst in-house education is important, the Inn-1 credit rewards 'substantial contributions to broader market transformation in South Africa'. The GBCSA would thus expect initiatives under this credit to have far-reaching tangible market transformation impacts. Education Facility: Live metering displaying daily and weekly energy usage of the building is to be continuously presented within the building to the immediate users as well as to secondary public groups via a building website allowing for public educational benefits and creating an awareness of Green Star SA as well as daily consciousness of sufficient energy consumption and water usage. Green Awareness Centre: the education centre will be set up to provide the public with information on green buildings, water saving, energy savings, recycling, organic materials and products. It will also run competitions that encourage people to reduce their carbon footprint. As 3rd Office The GBCSA notes that this initiative will facilitate increased market transformation of the South African property and construction sectors. The GBCSA notes that this is a commendable initiative provided that there is a contractual obligation to reserve this space for the education and awareness centre and the necessary documentation for Green Star SA is provided as per the requirements of the Green Star SA Office v1technical Manual. Urban Heat Island Effect Urban heat Island Effect: The vertical green wall reduces the indoor temperatures resulting in a reduction in cooling loads and energy loads. This results in a low energy consumption and substantial environmental reduction of CO₂ emissions. The GBCSA notes that using plants for shading and or thermal conditioning of buildings has been used in South Africa for many years already and as such this initiative is not worth a Green Star SA innovation point. Urban heat Island Effect: The building makes use of a vegetated roof and roofing materials with a solar reflectance index < 78 to reduce urban heat islands resulting in a low energy consumption and substantial environmental reduction of CO₂ emissions. The GBCSA notes that this initiative addresses a valid environmental concern outside of the current scope of this Green Star SA tool as therefore worth of an innovative point. Page 1 of 9

2 Urban heat Island Effect: Paving materials with an SRI of 29 have been installed for more than 50% of the site hardscape to reduce urban heat islands and minimize impacts on microclimates, humans and wildlife habitats. As The GBCSA notes that this initiative addresses a valid environmental concern outside of the current scope of this Green Star SA tool as therefore worth of an innovative point. Urban Heat Island: The entire roof area and exposed slabs will be waterproofed and due to the SRI properties of the waterproofing material it equates to the area being well above the 75% value required by the criteria. 3rd Office The GBCSA notes that this is currently outside the scope of this Green Star SA Office v1 rating tool, and as such the innovation claim is. Market transformation with respect to low VOC paints Market Transformation wrt low VOC paints: The design team has been instrumental in driving market transformation by significantly influencing the South African paint market in terms of the supply of low VOC paints. Cyclist facilities & As The GBCSA notes that the initiative results toward overall market transformation of the South African paint industry. Provision of bicycles: A total of 4 bicycles (2 male and 2 female) have been provided and are to all building staff to use during office hours. Helmets are also provided for safety purposes. Even though this initiative is positive and will influence some tenant behaviour, the GBCSA notes that this initiative is not deemed innovative in terms of the Green Star SA innovation criteria. Community Cycle Racks: a first occasion of the provision of such a public cycling facility in the Cape Town CBD (or anywhere in SA) and in addition assists to the transform the market from vehicle travel to more environmentally friendly bicycle travel. The GBCSA notes that the initiative is outside the current scope of this GSSA rating tool and has a substantial/significant environmental benefit as it incentivises use of alternative modes of transport- viz. Cycling to work- not only for the project but for the surrounding office buildings as well. Post Occupancy Surveys Productivity Study: A study will be conducted to assess building occupant perception of workplace wellbeing and productivity in relation to validated work productivity. World First in terms of productivity studies in Green s: The project has shown world leadership in implementing a three-stage productivity study including pre-occupancy surveys as well as two post occupancy surveys in evaluating the perceived benefits of green buildings and associated productivity gains. As As The GBCSA notes that this is a commendable initiative as it has a measurable positive effect on employee well being and productivity. The GBCSA commends the applicant for participating in this research which is seen as a global first. Post-Occupancy Research: The project is committed to conducting a Post Occupancy Evaluation (POE) on the building upon completion to evaluate how the building users experience and perceive the building and to examine actual building operational performance and productivity. 3rd Office The GBCSA notes that is a commendable initiative. Innovative funding Market transformation in pioneering innovative funding mechanisms for renewable energy: A joint venture which is a first of it's kind has been undertaken with the national utility for the provision of large scale building integrated renewable energy. The GBCSA notes that a joint venture with the national utility is significant in its potential for market transformation and increased uptake of renewable energy systems to both reduce greenhouse gas emissions and reduce pressure on the electricity grid. Innovative Contractual and Financial Arrangement: between the developers and a leading international renewable energy producer will result in significant environmental benefit and can contribute significantly to changing the South African and African renewable energy landscape in the commercial property sector. This initiative would qualify for an innovation point provided the necessary documentation for Green Star SA is provided as per the requirements of the Green Star SA Office v1technical Manual. Page 2 of 9

3 First Green Star SA Certified First Green Star SA Certified : this project was the first to target a Green Star office rating and remained committed to this despite the budget and time constraints. The GBCSA notes that this initiative is not deemed innovative for the purposes of Green Star SA certification. LED Lightning 1. First Commercial building in SA to have 95% LED lighting installed: Majority lighting scheme makes use of Light Emitting Diodes (LEDs) of the commercial building. About 99% of the lighting (including UA, common areas, parking and external areas) is LED. By designing the building the project team has ensured significant environmental benefits such as energy savings, maintenance savings and waste savings. Inn The GBCSA notes that the initiative is considered a first in South Africa for a an office building of this size. Green Star SA Accredited Professionals on Project Team Green Star SA Accredited Professional Team: the project has encouraged the project team to learn the Green Star principles by subsidizing the course and exam for the professionals. Green Star SA Accredited Professional Team: the entire project team are Green Star SA Accredited Professionals and thus the project has exceeded the Green Star SA benchmark for the Man-1 Green Star SA Accredited Professional credit. Solvent-free Paint Inn The applicant has submitted an innovation point for exceeding the Green Star SA benchmark for Man-1 Green Star SA Accredited Professional. As stated in the Round 1 assessment comments, this initiative would qualify for an innovation point if it can be demonstrated that all design team members, excluding the client, have passed the Green Star SA Accredited Professional exam. As not all design team members have passed the exam, the point is This initiative has qualified for an innovation point and it has been demonstrated that all design team members have passed the Green Star SA Accredited Professional exam. Solvent-free Paint: the use of solvent free paints will contribute to broader market transformation towards sustainable development in south Africa. These products contain no lead, no alkyl phenol ethoxylates, formaldehyde and or chloroisothiazolinone. Exceeding benchmarks for IEQ-13: the use of solvent free paint products will result in no solvents or VOC's being released while drying or during the life cycle of the paint. Black Water Treatment System The environmental benefit of this initiative does not warrant a Green Star SA innovation point. The environmental benefit of this initiative in relation to the benchmarks of the IEQ-13 credit does not warrant a Green Star SA innovation point. Black Water Treatment System: the blackwater treatment system is a first in a South African urban environment and results in water savings and reduction of discharge to the sewer. The point is for the initiative, for being among the first installations of a black water treatment system in a South African urban environment and contributing to market transformation in South Africa. Pressure wash system Pressure wash system: This system uses high pressure hoses to remove paint from brushes. The paint solids separate out to the bottom and the clear water is drained out and can be reused or disposed into sewer system. Inn Denied Green Lease The environmental benefit of this initiative is not deemed significant enough for a Green Star SA Innovation point. Green Lease: this is an initiative by the building owner and landlord to encourage improved environmental behaviour by tenants of the building. The lease agreement will require the tenant to submit management plans on waste, water and energy; monitor and report quarterly on energy, water and waste usage and submit an annual procurement policy to the landlord for the selection of environmentally friendly consumables. This initiative may be a worthwhile innovation strategy as the Green lease credit is not in the Green Star SA Office v1 tool, provided the necessary documentation for Green Star SA is provided as per the requirements of the relevant Technical Manual. Page 3 of 9

4 Green Lease: This initiative requires tenants to monitor the performance of energy, water and waste reduction of the building on an on-going basis and to prepare a procurement policy for the use of environmentally friendly consumables. This lease is signed by both the tenant and owner. The GBCSA notes that this is a worthy initiative. Exceeding benchmarks with respect to EMI-5 Watercourse Pollution Exceeding benchmarks for Emi-5: a storage capacity of 192m 3 has been designed for storm water run off and this exceeds the criteria of Emi-5 by 35% Stormwater treatment system design: The system is a first for a South Africa as it consists of a combination of horizontally and vertically configured aerobic trickle and anaerobic filter trays as opposed to the 'normal' constructed reed-bed type of system. Increasing the capacity of the stormwater system does not necessarily have a significant enough improvement in environmental impact beyond the Emi-5 credit criteria requirements to be innovation points for Green Star SA certification. Given the innovative approach to addressing stormwater quality treatment within extremely limited space constraints, the GBCSA notes that this proposed initiative may substantially contribute to the broader market transformation towards sustainable development with regards to stormwater quality. Exceeding benchmarks with respect to MAN-3 Tuning Maintenance: This initiative aims at eliminating the negative environmental impact by ensuring that building tuning and maintenance goes beyond the mandatory period. An additional 5 years beyond the mandatory 12 month maintenance and guarantee period will be implemented to ensure that building systems are operating to specification. To be as innovative, the GBCSA need to be satisfied that the 5-year maintenance contract has been agreed to by both the building owner and the maintenance contractor. Exceeding Tuning (Man-3): This initiative aims at eliminating the negative environmental impact by ensuring that building tuning and maintenance goes beyond the mandatory period. An additional 5 years beyond the mandatory 12 month maintenance and guarantee period will ensure that building systems are operating to specification. Inn As The GBCSA commends the project team for this initiative. Ice Storage Ice Storage: The system utilizes a chillier to produce ice during the night which is built and stored in tanks. This stored ice provides cooling during the day to meet the building's air conditioning load requirement. The technology is not new to South Africa or the world and is therefore not deemed eligible for Green Star SA innovation points as a first in South Africa or the world. Bricks with low embodied energy Use of bricks with lower embodied energy: The site makes use of clay bricks. This minimizes energy usage during clay bricks production thus limiting the negative impacts of greenhouse gas emissions on the environment. Inn Denied - Although the GBCSA commends the use of products where the manufacturer of the product has actively demonstrated a reduction in the embodied greenhouse gas emissions of a particular product (verified by a thirdparty organisation), in this instance the project team has failed to provided contractual evidence (i.e. extract(s) of specification) clearly demonstrating that the specific clay bricks will be used in the project. Use of bricks with lower embodied energy: The site makes use of clay bricks. This minimizes energy usage during clay bricks production thus limiting the negative impacts of greenhouse gas emissions on the environment. It is the GBCSA's opinion that full embodied energy assessment to be done according to international best practice standards undertaken by a third party independent expert/certifications body. Renewable energy production Renewable Energy Production to Alleviate South Africa's Power Shortage: a total of solar panels will be installed on the roof covering a total roof area of m 2. This will generate a total of kwh per annum resulting in a net CO 2 emissions saving of kg CO 2 per annum. The GBCSA notes that this is a commendable initiative provided that the necessary documentation for Green Star SA is provided as per the requirements of the Green Star SA Office v1technical Manual and that the project team is able to sufficiently demonstrate that such an initiative is considered a 'first' in South Africa Page 4 of 9

5 Recycling centre Community Recycling Centre: the recycling centre will provide an alternative and more sustainable waste management solution. It will guarantee the recycling efforts of the establishment are managed with optimum efficiency. In the long term, the centre is will be a local sustainable business that generates enough turnover to offset its operational costs. Treated effluent for heat rejection The project is pursuing Inn-3, however the short report does not follow the format of Green Star SA credits to identify the category and propose the Aim of, Criteria and Documentation Requirements, and then demonstrate that the proposed credit requirements have been met. In addition, the report does not justify how this credit would be different from other existing Green Star SA credits and does not articulate the nature and quantify the environmental benefit achieved. Treated effluent water for heat rejection contributing to broader market transformation: treated effluent is used for the heat rejection system as opposed to the typical potable water often used. This results in the building saving approximately 94% of the potable water demand for heat rejection. The GBCSA acknowledges that this initiative undoubtedly has a large environmental benefit provided all the necessary documentation for Green Star SA are provided. Heat rejection water: The building will make use of treated effluent for heat rejection cooling and share the details of how to implement this system to all 14 other buildings in the precinct. This has the potential of reduction water consumption due to heat rejection by 1400%. The GBCSA notes that whilst there may be potential for 14 buildings to use the treated effluent for heat rejection purposes, there is no guarantee that any other buildings will in fact do so and the project team has not provided sufficient proof as to how the proposed 'public information document' will be made to prospective developers in the precinct development. Treated effluent for irrigation Treated effluent for irrigation: This initiative makes use of treated effluent water for irrigation purposes. The system does not use any potable water and reduces the potable water consumption by 22%. The GBCSA does not believe that this initiative is exceeding Green Star SA benchmarks. Exceeding benchmarks with respect wrt to Wat-3 Landscape irrigation Exceeding Green Star SA benchmarks - landscape irrigation: the specific negative environmental impact caused by excess irrigation and inappropriate plant choices has been eliminated through the use of xeriscaping with indigenous species and soil improvers. Landscape Irrigation water reduction: the consumption of portable water for landscape construction has been reduced by well over 50% (probably 90-99%) and for landscape irrigation by at least 90%. The GBCSA notes that this initiative is not deemed innovative for the purposes of Green Star SA. The GBCSA notes that it is not possible to achieve a restorative environmental impact as the specific negative environmental impact has not been eliminated. Exceeding Green Star SA benchmarks - landscape irrigation: The project achieves a 100% reduction in potable water for irrigation thereby exceeding the Green Star SA benchmarks. The GBCSA notes that whilst the reduction in portable water use for landscape irrigation is commendable, it is not viewed as a significant enough improvement beyond the Wat-3 Landscape Irrigation credit criteria requirements. Recycled water Recycled water use during construction: Greywater from the showers an stormwater adjacent to the building will be reused on site to reduce clean water consumption. The water will be tested monthly to maintain DWAF standards for irrigation and mixed with stormwater for dust suppression and toilet water for the construction workers. Urban consolidation While the GBCSA acknowledges that this is indeed a sustainably responsible implementation, this is not considered innovative due to the magnitude of environmental impact in comparison to other credits relating to the issue of water consumption within the rating tools. Page 5 of 9

6 Urban consolidation: Compact development patterns that increase land utilisation efficiency. Note: This credit was as an innovative point for Green Star SA - Multi Unit Residential (MUR) PILOT projects as it was only proposed for inclusion as a credit in MUR v1. 1st Multi Unit Residential The GBCSA notes that is initiative is an excellent example of how urban consolidation can be achieved. Only to PILOT projects as an innovation point. Radiant space panels Radiant space panels: These panels will be installed to ensure fast response impact load heating and cooling within the space. These panels will also act as space dividers. Bottom 'hung' blinds The application of radiant panels, is not considered innovative as it is currently implemented in various forms within the market. Bottom 'hung' blinds: The blinds in the building are 'hung' in the bottom and automatically adjust their level according to the level of direct sun rays. Even though this initiative is positive and somewhat innovative, the GBCSA notes that this initiative is not deemed innovative in terms of the Green Star SA innovation criteria. Rock store simulation tool Rock store simulation tool: A simulation tool has been developed to estimate the effect of rock store thermal storage on the energy consumption of the building. Exceeding benchmarks with respect wrt to ENE-5 Peak Energy Demand Reduction The GBCSA notes that the simulation tool is the intellectual property of the project and for explicit use on commissioned projects and is thus limited in its ability to substantially contribute to the broader market transformation towards sustainable development in South Africa. Reduction of Peak Energy Demand: The energy initiatives result in substantial (>5% above neutral) restorative environmental impact. Inn Peak Demand reduction: On-site electricity generation eliminates the total impacts of the project by meeting 100% of the peak demand and also results in a substantial (>5% above neutral) restorative environmental impact. Inn Exceeding benchmarks with respect wrt to ENE-1 Greenhouse Gas Emissions As The GBCSA commends the project team for achieving substantial peak energy reduction. The GBCSA commends the project team for achieving substantial reduction in peak energy demand. Reduction of Greenhouse gas emissions: Through the use of renewable energy, the building results in a substantial (>5% above neutral) restorative environmental impact. Inn Exceeding benchmarks with respect wrt to TRA-2 Provision of Car Parking The GBCSA commends the project team for achieving a substantive (e.g. 5% or greater above 'neutral') restorative environmental impact. Reduction of offsite parking: the building is positioned within the parking area of an existing campus and the construction has resulted in complete elimination of 140 parking bays which have not been replaced anywhere on campus. Fewer parking bays and consequently fewer cars have a positive environmental impact. The GBCSA notes that this initiative is not considered innovative. Greywater system Greywater Recycling Plant: Grey water will be collected from showers and basins and used to flush toilets and for irrigation The GBCSA notes that the recycling of shower and wash hand basin water is currently implemented in numerous buildings and is thus not considered a South African First. Recharging infrastructure for electric cars or bicycles Page 6 of 9

7 Recharging Infrastructure for Electric Cars: 6% of the parking bays on the site have been furnished with plug points for electric vehicle charging. The charging points use electricity that has been generated from an energy centre using natural gas turbine generators. Electric car charging points: The electric car charging points infrastructure have been designed and constructed for the project. This is a first for South Africa and will facilitate market transformation. As The GBCSA notes that this initiative is a first for South Africa. The GBCSA notes that this initiative is a first for South Africa. Electric Car Charging Bays: an electric vehicle charging station is an element in the infrastructure that supplies electric energy for the recharging of plug-in electric vehicles. This is to promote and encourage the use of completely electric vehicles rather than hybrid or petrol vehicles in SA. Denied - The GBCSA notes that while this is a commendable initiative, the project team has not included any tender/construction drawing or other contractual documentation to demonstrate on demonstrating that the electric car charging points will be installed in the project. Electric Bicycle Charge : 24 charging plug points to charge batteries of electric bicycles will be provided for the staff members. Denied - The GBCSA notes that while this is a commendable initiative. However, the project team have failed to provided to demonstrate that this is indeed a first in the world or in South Africa. Trigeneration CHP Plant: The use of the combined Heat and Power plant to generate power is 45% cleaner than the Eskom coal fired generation and results in a reduction of tons of CO 2 annually. As The GBCSA notes that this initiative is worthy of a Green Star SA innovation point. CHP Plant: The use of the combined Heat and Power plant is designed to produce 2MW of power. It generates electricity with an 80% reduction in carbon emission. Commissioning Training The GBCSA note that from the submission it is clear that the initiative is the second commercial office Trigeneration installation of this magnitude in the South African built environment. It is the opinion of the GBCSA that this initiative contributes to the broader market transformation towards sustainable development in South Africa. CIBSE Commissioning Training: All of the professionals and contractors were given onsite training workshops on the CIBSE commissioning methodologies. The knowledge transfer will make a significant differences in commissioning building services in the future. River clean up The GBCSA notes that this initiative is not deemed innovative for the purposes of Green Star SA. River clean up: This clean up initiative involved clearing alien plants, pruning existing trees, treatment of existing cut tree stumps to prevent further growth, collection and removal of rubbish The GBCSA commends the project team for the important rehabilitation work undertaken on the Plankenberg River. River clean up: This clean up initiative involved clearing alien plants, pruning existing trees, treatment of existing cut tree stumps to prevent further growth, collection and removal of rubbish As The GBCSA commends the project team for the important rehabilitation work undertaken on the Plankenberg River. Green Roof Green Roof: This initiative has exceeded the international norm of designing for a maximum of 30 species of plant by designing and installing in excess od 80 species of plant. While this is a commendable initiative, the project team has failed to provide the necessary documentation for Green Star SA certification as per the requirements of the Green Star SA Office v1 Technical Manual. Energy Efficient HVAC Page 7 of 9

8 Energy Efficient HVAC: A fresh air system preheats the outside air with a combination of heat recovery ventilators and Solar Hot Water coils completely eliminating the ventilation energy load and resulting to less energy consumption by the HVAC equipment thereby reducing the building's carbon footprint. Urban Farming The GBCSA notes that this initiative is already rewarded under Ene-1, and this initiative on its own is not substantial enough to be considered as an innovative first in SA. Urban Farming : A 588m2 garden will be planted with seasonal vegetables, herbs and fruit trees so as to provide fresh produce for use in the building. Mixed Mode HVAC system & warning Light System This is an innovative initiative in the commercial property context. Mixed Mode HVAC system & warning Light System: The system works in conjunction with the ventilation system incorporated within the building, to minimize electricity consumption for cooling and heating. The light will change colour from red to green, indicating and delegating to the building occupants when to make use of either mechanical ventilation or sufficient natural ventilation. Stairs Denied - The GBCSA notes that while this is a commendable initiative, the project team has failed to provide the sufficient justification on how the initiative will cause broader market transformation in the market and to articulate what the cumulative environmental benefit of this initiative would be. Stairs: Prominent stairs have been provided near the entrance of the building to encourage building occupants to take the stairs and promote the well-being of occupants. Solar Car Charging As The GBCSA notes that this initiative addresses a valid environmental concern outside of the current scope of this Green Star SA tool as therefore worth of an innovative point. Solar Car Charging: The project provides a showcase unit of solar powered electric car charging station for permanent installation on the site as both a showcase for the technology as well as a national precedent highlighting alternative fuel vehicles as a means of reduced CO2 emissions travel. Inn Public Private Partnership Contract Public Private Partnership Contract: The notable features of the PPP model are that a strict contractual relationship exists between the lessor and the lessee with significant penalties over the 25 year life of the contract. The platform provide for the DEA project contractually mandates a 4 star building with a max annual energy demand of 115kWhr/ m2/ annum and that 10% of all energy be from renewable sources over the life of the contract. This provides the project with the opportunity to design an optimised building and then to run it as designed for 25 years to ensure that the contractual conditions are met. Inn The PPP initiative itself is not considered an innovative strategy as many PPP projects have been applied locally and internationally. However, the specific clauses within the PPP project which require innovative commitments to environmental performance are considered innovative. Examples are such as the energy clauses and performance commitments for 25 years. The GBCSA recognises that the model provides a far more rigorous contractual and large scale framework in which the transformative adoption of green buildings can be achieved at a large scale. Weather Station Weather Station: The project has incorporated an internationally certified and calibrated meteorological weather station that is to be fitted on the roof of the building. Exceeding benchmarks with respect wrt to Ene-3: Lighting Power Density It has not been clearly demonstrated how will the project will transform the market beyond this specific building through this initiative? Lighting Power Density: Exceeding the current upper limit of current Green Star v1 tool, the broader transformation potential of exceeding the lighting power density credit point bands of the existing credit are the influence the project has as a showcase role in the market and the ability to focus on a potential revision of the Green Star credit criteria that moves the benchmark in a future version to once again realign with the rate of technology growth in the lighting industry. The GBCSA note that suppliers are already rolling these fittings out within South Africa, as well as LED technology with low lighting power density however, and such market transformation is already in place. Also, please note that in later versions of the Green Star SA tools, the introduction of a lighting energy calculator allows project teams to gain benefit for improvements beyond the benchmarks in the current Office v1 tool. Page 8 of 9

9 Exceeding benchmarks with respect wrt to Mat-5: Concrete Concrete: the project has achieved a 47% slag replacement value which is 7% above the 40% value stated above and thus exceeded the Green Star SA benchmark by more than 5%. Exceeding benchmarks with respect wrt to Mat-6: Steel The GBCSA notes that whilst the increase in the reduction in Portland cement use for concrete mixes is commendable, it is not viewed as a significant enough improvement beyond the Mat-5 Concrete credit criteria requirements as cement is still being used and thus not eliminating the specific negative environmental impact as required by the Inn-2 credit. Steel: the project has been designed to significantly exceed the Green Star SA requirements with 95.87% of all the steel in the building having a post-consumer recycled content of 100%. Vermicomposting The GBCSA notes that whilst the reduction virgin steel use is commendable, it is not viewed as a significant enough improvement beyond the Mat-6 Steel credit criteria requirements as virgin steel is still being used and thus not eliminating the specific negative environmental impact as required by the Inn-2 credit. Vermicomposting: Vermicomposters have been installed onsite to deal with organic waste that is produced and the compost used to feed the plantings located at the entrance as well as the trees along the perimeter of the site. Fire Suppression Gas GWP The GBCSA notes that it is not clear from the documentation submitted whether the worm farms to remain after construction to serve the building. If the composting is to remain for the building operation, the GBCSA would suggest targeting this under Inn-2 for recycling waste storage. Fire Suppression Gas GWP: Considering the GWP of fire suppression gas Inn The GBCSA awards this innovation under the Inn-02 'Exceeding Green Star Benchmarks' credit. Page 9 of 9
