ENERGY AND GREENHOUSE GAS EMISSIONS | continued Indicator descriptor Sustainable or renewable energy supply Indicator Percentage of dwellings built by Landcom to be fitted with solar hot water systems capable of achieving a minimum of 30 RECs or 19 RECs for dwellings of two or fewer bedrooms Percentage of dwellings to be fitted with gas boosted solar hot water systems to meet at least 60% of energy requirements for the year Percentage of projects greater than 500 dwellings to achieve more than 50% reduction of greenhouse gas emissions compared with NSW average greenhouse gas emissions Percentage of projects with over 500 dwellings to achieve more than 40% reduction of greenhouse gas emissions compared with base case (and including a percentage of renewable energy generation) Target 2009/2010 to 2014/2015 Result 2010/2011 Result 2009/2010 100% 18% 11% Target 2002/2003 to 2008/2009 N/A N/A N/A 100% 100% Indicator in testing phase Methodology under development N/A N/A N/A 100% 2008/2009 2007/2008 2006/2007 No data - indicator introduced in 2009/2010 41% (93 out of 227) 47% (224 out of 477) 18% (29 out of 160) No data - indicator introduced in 2009/2010 N/A (Note 1) N/A (Note 1) 100% (1 out of 1 projects) Energy efficiency We reduced greenhouse gas emissions in detached and attached dwellings built by Landcom by 48% which was short of our 50% target. Generally, progress has been steady since 2003, with emissions decreasing from 30% emissions reduction to 48% emissions reduction, but still short of our target. The reason for the lag in the greenhouse gas reduction achieved compared to the regulatory minimum, and to Landcom’s target, is because each year’s results include dwellings which gained planning approval ahead of these targets being in place. Again this year, agreements with our delivery partners had been prepared well before the new, more challenging targets were determined. In the past, we calculated our emissions reduction using a method developed by the Energy Smart Urban Solutions (ESUS) project. This has been replaced by comparing our reductions to the New South Wales average, as defined by BASIX. Reduction in greenhouse gas emissions from Landcom dwellings compared to NSW average 60% Percentage of projects greater than 500 dwellings to include a minimum of 5% renewable energy supply, either onsite or offsite Percentage of projects with over 500 dwellings that include a component of renewable energy generation either onsite or offsite 100% Indicator in testing phase Methodology under development N/A N/A N/A 100% No data - indicator introduced in 2009/2010 N/A (Note 1) N/A (Note 1) 100% (1 out of 1 projects) 55% 50% 45% 40% 35% 30% 25% 20% 15% 10% 5% 0% GRAPH 5 GOES HERE Landcom policy target 2010 BASIX requirement 2006 Landcom BASIX 2003 base case requirement 2004 2004/5 2005/6 2002/3 2003/4 2006/7 2007/8 2008/9 2009/10 2010/11 Note 1: Renewable energy output for masterplanned projects completed this year was not determined at the time of reporting. % reduction calculated from BASIX scores (new indicator) % reduction calculated from previous indicator The graph above shows the results, using our current and previous methodology. It also shows how the regulatory standard has changed. Results are similar from both calculation methods up until 2009, when the ESUS methodology gives a smaller greenhouse gas reduction. As mentioned previously, we have no result for our only commercial building, Park Central, and the NABERS rating indicator and the methodology for collecting the data have been changed. 38 landcom annual report 2011
Only 19% or 29 out of 152 dwellings achieved a 6 star or greater thermal performance. If we remove the projects assessed before the 6 star rating became possible, and report only on those 118 dwellings to which the latest version of Nationwide House Energy Rating Scheme (NatHERS) can be applied, this result increases to 25%. Once again, we recognise that to achieve our target, we will need to raise awareness among our own project teams, as well as among our partners, to ensure that this target is properly understood and implemented. 100% 90% Percentage of Landcom dwellings achieving NatHERS 4.5 stars or better renewables sources. As signalled last year, the methodology we will use to measure this is our PRECINX ® software, which we’ve developed in partnership with carbon consultancy Kinesis. We tested our methodology during the reporting period and, from July 2011, we will be reporting on projects from the masterplan stage through to completion. Projects that completed their masterplan before 1 July 2011 will not be reported under this indicator. Also excluded will be projects where Landcom has limited influence over sustainability outcomes due to partnering arrangements. Percentage of Landcom dwellings with solar water heating Eco-Living at The Ponds casestudy In partnership with Clarendon Homes, we launched our first Eco-Living demonstration home at The Ponds this year. These homes will showcase sustainable design, materials and technologies. Our aim is to increase community and industry awareness about sustainable house design and products and create more demand for them. The first home is the Benchmark Home, which achieves a 6 star thermal performance, a 60% BASIX energy rating and a 70% BASIX water rating. Our next home to be completed will be the Green Cycle Home, which will demonstrate ways to maximise the use of recycled materials or those with high recycled content. The final home is the Zero Emissions Home, which will demonstrate how to achieve net zero energy use and emissions and net zero water use. All homes will feature universal housing principles, making them flexible to meet the needs of people of different abilities and ages over time. They include widespread use of sustainable materials and products. Special attention has been given to design features that encourage community interaction, passive surveillance and the provision of asthma-friendly internal and external spaces. 80% 70% 60% 50% 40% 30% 20% 10% 0% BCA requirement for 5 star (doesn’t apply in NSW) 2006/2007 2007/2008 2008/2009 2009/2010 2010/2011 % of dwellings with > 4.5 stars (previous) BCA requirement for 6 star (doesn’t apply in NSW) The chart above shows the proportion of dwellings achieving better than a 4.5 star rating, and changes in regulation over the period. The Building Code of Australia introduced national requirements for 5 star homes in 2006. This increased to a 6 star rating in 2010, but these requirements don’t apply in New South Wales, where energy performance is regulated by BASIX. While we are still short of our target, there has been steady progress over the years, particularly when our performance is assessed against the 4.5 star rating. In the current year 78% of Landcom dwellings achieved better than 4.5 star ratings, a vast improvement from the 20% which achieved 4.5 stars just under a decade ago. There is a 30% improvement in energy use from a 4.5 star dwelling compared to a 6 star dwelling. Achieving our target will not occur without a greater effort on our part to work with partner builders to create the momentum to improve on these results. As a first step, we are working with Clarendon Homes to develop three Eco-Living display houses at The Ponds that have a range of features beyond BASIX requirements (see case study on this page). Promoting sustainable or renewable energy supply We aim to have all large projects (defined as having over 500 dwellings) reduce their greenhouse gas emissions by more than 50% and to source at least 5% of their energy supply from 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% 2006/2007 2007/2008 2008/2009 2009/2010 2010/2011 The graph above shows the proportion of Landcom dwellings with solar water heating. This rose from zero in 2003 to nearly 60% in 2010, although we saw a significant fall in 2011 to 39%. Despite this, the numbers are still better than the state average, which only reached 31% in 2008. The 39% of Landcom dwellings that have solar hot water systems is comprised of 18% with heaters that meet the performance standard and 16% that don’t. 5% had no information about the heater’s specification. Only 18% of the dwellings we built were fitted with solar hot water systems capable of achieving a minimum of 30 RECs or 19 RECs for dwellings with two or fewer bedrooms. Encouraging better compliance is at the top of our list of priorities for the coming year. From our investigation of the data, there is no apparent reason why the numbers fluctuate as much as they do. The installation of solar water heating should be a cost-effective solution for consumers, but from the limited audit we have undertaken, it would appear that RECs are not being claimed by either builders or consumers. We have been unable to determine any logical reason to explain why this is occurring and so in the coming year we will work with our supply chain to actively encourage better take-up of solar water heating.
