1 Annual Benchmarking Report 2013

2 2 Benchmarking Report 2013 Welcome and Introduction There have been a significant number of changes to the International Sustainability Alliance (ISA) over the past year and I am very pleased to be able to welcome you to our fourth annual benchmarking report. ISA is no longer an limited liability company. At the very end of 2012 the membership decided to fully integrate with BRE and in doing so, be at the forefront of thought leadership in the built environment. This adds to our credibility and strengthens governance. Most importantly, it ensures that we remain as a not for profit membership organisation whose profits are distributed by the BRE Trust. Unlike other benchmarking schemes, the ISA benchmark is dynamic. Instead of receiving a benchmark report once a year with data that is 18 months old, the new and improved ISA online database can produce organisational benchmarks as soon as data is entered. In addition, we are able to produce benchmarks at site, building and asset level, rather than at the less precise portfolio level. As a result of these changes, membership levels have remained buoyant. Whilst the recession has undoubtedly had an impact particularly with respect to members based in the Netherlands we have seen the database expand to include a number of British companies such as Royal Mail (one of the UK s leading logistics companies) and Rexel, who are equally prominent in business to business distribution. In September this year, we were particularly pleased to announce that a South American branch of ISA has been set up by our colleagues in BRE Brazil. We are already in discussions with a number of São Paulo based owners, occupiers and investors and look forward to welcoming many new members in due course. Perhaps the most significant venture however, has been the recent enrolment of the Qatar Green Building Council as a Strategic Member of ISA. Linkage with such an eminent body is very welcome and we hope that both memberships will be able to profit from the relationship. We now have 16.5 million square metres of property within the ISA database which amounts to over 150 billion worth of assets. Our Portfolio Members in Belgium (Bopro), France (Egis Conseil Batiment) and Italy (Habitech) are adding data and providing their clients with assessments based on that data. Each report we generate is now given an ISA benchmark logo which members are free to use in their annual reports to indicate that their data has undergone third party review by BRE. Philip Buttery, Chief Executive, ISA Welcome to the fourth Annual Benchmarking Report from ISA the International Sustainability Alliance. ISA is a not-for-profit membership organisation formed by leading corporate owners and occupiers, property investors and developers.

3 3 6/10 Energy 7/10 Overall Score 6/10 Water 8/10 Waste We have also introduced an overall score for property portfolios held by members within the ISA database. These can be further sub-divided by site, building and asset, by sector and by country or geographic region. The ISA performance score is determined by a compound statistical assessment which determines how a building relates to its peers within the ISA database. Whilst seen by some as being brutally honest, we nevertheless believe these scores are fair. ISA is not a consultancy and the data, of course, is provided by the members themselves. Sustainability Directors find the scores invaluable as they enable them to challenge the performance of Facilities Managers. One of our members for example, uses the ISA score to differentiate between good Facilities Managers who manage poor buildings from poor Facilities Managers who manage good buildings. Finding out how your buildings perform is not the only benefit of ISA membership. We continue to remain engaged with the European Commission and earlier this year assisted them in the preparation of the question set for the Commission s public consultation on Sustainable Buildings. Our networking events continue to be popular. We held four this year, in Hamburg, London, Paris and Ghent. Now with a new format, we generally have at least 2 member speakers and a guest speaker at each event. Topics this year have been at the cutting edge of developments in the built environment and have included The Value of Green Investment and Ecosystem Resilience. During the course of the day members take the opportunity to network and share best practice with fellow industry leaders. All benefit from the legal updates on emerging legislation we provide. We have 5 categories of membership. Founding Membership is currently closed to new entrants but if you have data and would like to enter it into our online tool for an immediate organisational assessment which can be set against an international benchmark - we have General Membership. If you have data and would prefer to try our online tool with no further obligations, we have Affiliate Membership. If you do not have data and wish to attend our networking events, be involved in research programmes and receive our newsletter we have Associate Membership. Finally, if you have data but want someone else to enter it into the ISA system for you thereby saving additional resource costs - we have a number of consultancies who can do it for you. These include BRE, Egis Conseil Batiment, Bopro, Habitech, Qatar Green Building Council and BRE Brazil. This group are called Portfolio Members and each can offer first class guidance and advice on how your portfolios are performing. Membership fees are explained in our What is ISA? brochure, which is available on our website. If you want to speak to a Portfolio Member or would be interested in becoming one, please let me know. ISA is a service provided by BRE. It therefore provides information about properties based on sound scientific advice of the highest quality and integrity. Philip Buttery, Chief Executive, ISA

5 5 What Our Members Say ISA s key performance indicators and benchmarks of sustainability performance are providing property investors, owners, managers and occupiers with important insights that will help to ensure the sustainability and future value of their properties. Many of these forward-thinking companies are members of ISA, which brings together a wide variety of leading commercial organisations with substantial property interests and a shared focus on improving sustainability. Here is a selection of comments from our members. We believe that one of the main benefits of joining ISA is that it has helped us to structure our thinking with regard to our data collection process says Louise Boustani of Aberdeen Asset Management. It is important to see that some of the issues that we are facing are universal issues and ISA membership allows us to talk through some of problems with other ISA members and BRE staff. Since joining ISA we have tried, where possible to collect environmental data on all the assets that we manage. EDF Group are another global leader who have been involved with ISA from the outset. We are committed to control and minimize the environmental impact of our activities; including pure tertiary activities such as building operation says Magali Saint-Donat of EDF Group. We occupy more than 5,000,000 m² of office buildings in approximately 10 countries throughout the world. ISA provides EDF Group with an opportunity to gather environmental data for our buildings in a unique database. This database allows for easy reporting and to benchmark our buildings to their peers, within EDF Group but also with the buildings of other members, which is important, in particular, in countries where we have few buildings. Some members join ISA with no immediate interest in entering data on properties they own or occupy. Joining ISA fits our strategic objective to foster the growth of innovative, sustainable development for the whole of Qatar says Meshal Al-Shamari, Director of Qatar GBC. ISA plays a leading role in sustainability benchmarking on an international basis, and membership will open up new avenues and opportunities for companies operating in Qatar and will undertake an important role in raising awareness about green development. Qatar GBC are one of a number of organisation who are using the strategic opportunity provided by ISA, and will be working with businesses throughout Qatar who wish to make use of ISA services. German building consultancy, ES EnviroSustain GmbH is one of the newer members of ISA, becoming an associate member in Through their offices in Frankfurt, Stuttgart, Berlin and Flensburg, ES EnviroSustain s interdisciplinary team of architects, engineers and geologists offer consultancy services that focus on the energy efficiency and sustainability of new and existing buildings. As an associate member, ES EnviroSustain gain access to ISA s extensive database of property sustainability, compiled using consumption data from members who include corporate real estate owners, occupiers, developers and investors. Our real estate consulting services focus on making the built environment more sustainable, said ES EnviroSustain s Managing Director, Dr Birgit Memminger-Rieve. From our daily work we know how important consistent metrics are to measuring environmental performance, and how it is sometimes difficult to gather reliable data. Through our ISA membership we would like to actively support enlarging the ISA database, and to show our clients that being sustainable brings added value to their properties. The reports have helped us more to focus and structure our thinking on the issues at hand and to help us to determine suitable environmental strategies. Louise Boustani of Aberdeen Asset Management

10 10 Benchmarking Report 2013 ISA Fundamentals Definition of property levels: A fundamental concept of the ISA system is the ability to recognise and where appropriate link three different levels of property unit : sites, buildings and assets. Building Asset Site Sites comprise a number of buildings which are in close proximity which are either detached or semidetached units which may have separate entrances and may be occupied by more than one organisation. Building refers to a single property unit which may be detached or semidetached and generally has a single main entrance and a unique postal address. There may be more than one organisation occupying / being responsible for the environmental performance of a building. Asset refers to a property unit which forms part of a building. An asset is a part of a building which is (or could be) occupied by or controlled by a single organisation. Shared spaces within multiple occupancy buildings (common areas) are also identified as separate assets within ISA. These property levels enable performance data to be entered into the ISA system by different users at the asset and building level and, provided the links between the property units are defined, the system will aggregate performance to the building or site level as appropriate. Definitions of Floor area: For sites and buildings the ISA system accepts floor area data entered as either GIA (Gross Internal Area) and/or GLA (Gross Lettable Area) and/or NA (Non-lettable Area). Users are encouraged to provide floor area data for sites or buildings as GIA (Gross Internal Area) wherever possible, as this is the primary metric used for the ISA benchmarks for these property levels. Gross Internal Area (GIA) (m 2 ) - Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level. In a single occupier building, the concept of GLA is not relevant, however, in a multi-tenanted building where there are shared/common areas these are classed as nonlettable areas and here the GIA will be the sum of GLA (for all tenants) plus any NA. Gross Lettable Area (GLA) (m 2 ) - Gross Lettable Area of a unit is the floor space contained within a tenancy at each floor level measured from the inside of main faces of external walls and, where applicable, the inside faces of internal inter-tenancy, partition and common area walls. The diagram above shows an example of how it applies to multi-tenanted offices. Non-lettable Area (NA): Non-lettable Areas or common areas are understood to be that floor space within an owner s building from which an income cannot be derived. Examples include common use areas, lift lobbies, stairwells, plant and technical rooms. For the purposes of ISA Key Performance Indicators, it has been agreed that parking areas whether enclosed, multi-storey or surface facilities, will be excluded from nonlettable areas. Defining the property type: For buildings and assets there is a three tier categorisation system for property type. This categorisation is used to derive benchmarks at a suitably distinct level.

11 11 Key Performance Indicators (KPIs) For each portfolio of properties, ISA members collect and enter data relating to energy, water and waste impacts of their property portfolio, from which the ISA system generates a total of 9 Key Performance Indicators (KPIs). Of these, 3 intensity KPIs can be used to generate benchmarks for similar properties (building type and country/region) against which members can compare their performance at building, country/region and portfolio level: Impact What s Measured Units Energy Energy consumed Total indirect energy consumption kwh/yr Total direct energy consumption kwh/yr Building energy intensity kwh/m 2 /yr Renewable energy On-site renewable energy generation kwh/yr generated Emissions of greenhouse gases Total direct & indirect greenhouse gas emissions kgco 2 e/yr as a result of energy Total direct and indirect greenhouse gas consumption emissions intensity kgco 2 e/m 2 /yr Water Water consumed Total water withdrawal by source m 3 /yr Building water intensity m 3 /m 2 /yr Waste Waste produced and disposal methods Total weight of waste by type and method of disposal tonnes/yr 1 BRE research. 2 Sustainability Reporting Guidelines and Construction and Real Estate Sector Supplement, version 3.1. GRI CRESS provides sector specific guidance for the construction and real estate companies based on the Global Reporting Initiative (GRI) G3.1 Sustainability Reporting Guidelines. 3 The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (Revised Edition) WBCSD and WRI. 4 EPRA Reporting, Best Practice Recommendations on Sustainability Reporting, September 2011, European Public Real Estate Association. In addition to supporting sound cost and risk management for core utilities and services, the ISA KPIs and benchmarks can contribute directly to effective, evidence-based reporting of operational impact performance and reduction as part of annual Corporate Responsibility and/or Sustainability Reports. Estate-specific reporting of energy and environmental impacts especially accompanied by a breakdown of the portfolio by building, building type or region is still relatively uncommon in corporate sustainability reports. 1 ISA members can use their portfolio KPIs to demonstrate the effect of their impact reduction strategies and their performance relative to sector and regional norms. The ISA KPIs can be used to support corporate sustainability reporting in line with recognised protocols including GRI CRESS 2, GHG protocol 3 and EPRA 4. This table outlines the KPIs that ISA use as the basis for its benchmarking and reporting. The KPIs

12 12 Benchmarking Report 2013 have been developed following consultation with external experts and members and are in line with reporting protocols specific to global real estate companies and fund managers. This set of KPIs came into effect in January KPI Title and Description GRI CRESS Ref EPRA Ref Metric 1 Total indirect energy consumption EN4 3.1 & 3.2 kwh / year This KPI collates consumption of energy within a property, where the energy is generated off-site. Energy consumption is reported in kwh per annum, or extrapolated from a known volume over a specified period. This information is entered by the user and is generally available from utility bills or meter readings. Sources of indirect non renewable energy could include: electricity, heating and cooling from low carbon technologies, steam, nuclear energy and other forms of imported energy. Sources of indirect renewable energy sources could include: solar, wind, geothermal, hydro and biomass or hydrogen-based intermediate energy. KPI 1 has 2 sub-groups whereby indirect energy consumption is reported as (1a) total indirect energy from electricity and (1b) total indirect energy from imported heating and cooling. Calculation: KPI 1a + KPI 1b NOTE: This indicator excludes direct energy generated from within the boundaries of the company 2 Total direct energy consumption EN3 3.3 kwh / year KPI 2 collates consumption of energy units of all incoming fuel sources used to generate energy on site. Sources of direct non-renewable fuel purchased could include: coal, natural gas, fuel distilled from crude oil including gasoline, diesel, LPG, CNG, LNG, butane, propane or ethane. Sources of direct fuels for renewable energy onsite generation could include biofuels, ethanol, biomass from offsite (processed or non-processed) and hydrogen This information is entered by the user. KPI 2 has 2 sub-groups whereby direct fuel consumption is reported as (2a) total energy from all sources except biomass and (2b) total consumption from biomass-fuelled sources. 3 Building energy intensity CRE1 3.4 kwh / m 2 / year This KPI reports the total energy consumption for a property over a specified period. Investors or owners can not only compare the total energy consumption of a property against its peers but also by variations including total energy consumed per full time employee (FTE); total renewable energy produced or consumed; or total non-renewable energy consumed. Calculation: (KPI 1 + KPI 2) / m 2 NOTE: Different energy sources have different carbon contents so sources should be reported separately where possible. 4 On-site renewable energy generation EN3 n/a kwh / year This KPI reports the direct on-site production of renewable energy, reflecting the GRI energy balance calculations. Sources of direct renewable energy could include: solar; wind; geothermal; hydro, biomass based intermediate energy; waste based energy, and hydrogen based intermediate energy. Calculation: KPI 1 + KPI 2 NOTE: On site renewable energy generation sold to the network should not be included. 5 Total direct and indirect greenhouse gas emissions EN & 3.6 kg CO 2 e / year This KPI calculates the total GHG emissions resulting from all direct and indirect energy consumption including biofuels and waste incineration. Equivalent CO 2 (CO 2 e) is a measure used to compare the emissions from various greenhouse gases based upon their global warming potential using effect of kgco 2 as base unit. *** Examples of such greenhouse gases include carbon dioxide, methane, fluorocarbons and nitrous oxide. 6 Total direct and indirect greenhouse gas intensity CRE3 3.7 kg CO 2 e / m 2 / year This KPI reports on annual GHG production intensity in properties of similar use per their relevant area. It can also provide an indicator of property energy efficiency of consumption and performance in that any property reporting above the average value of kg CO2e/m2/yr should be able to improve performance to at least the level of better performing comparable properties. In the long term it should be possible to provide this KPI on a more granular country/climatic zone basis. Calculation: (KPI 5) / m 2 7 Total water withdrawal by source in cubic metres EN8 3.8 m 3 / year

13 13 KPI 7 reports the total volume of water withdrawn (water consumed within the boundaries of the property i.e. site, building or asset) in cubic meters per year (m 3 /year) by the following sources: Purchased potable (drinking) water, ground, rain and surface water and water from other sources. This information is entered by the user and generally available from utility bills or meter readings. KPI 7 reports water consumption over 8 sub-categories: (7) Potable water from public water supplies; (7a) Groundwater; (7b) Rainwater (untreated); (7c) Rainwater (treated), (7d) Grey water; (7e) Treated (industrial process) waste water; (7f) Surface water (lakes ponds and streams); and (7g) Other water sources, unspecified. Calculation: KPI 7 + KPI 7a + KPI 7b + KPI 7c + KPI 7d + KPI 7e + KPI 7f + KPI 7g = Total water use at site 8 Building water intensity CRE2 3.9 m 3 / m 2 / year KPI 8 reports the total water consumption per annum (m3/yr) against the total floor area (m2) for the reporting organisation s operations including assets occupied and assets owned, where required. This KPI allows members to compare water intensity between properties of similar use per their relative area. It can also provide an indicator of water efficiency in that any property reporting above the average value of water consumption should be able to improve performance to at least the level of better performing comparable properties. Calculation: (KPI 7) / m 2 9 Total weight of waste by type and method of EN & 3.11 tonnes / year disposal KPI 9 reports the weight of waste in tonnes broken down by type (hazardous or non hazardous) and disposal method (the method by which waste is treated or disposed), on an annual basis. This information is entered by the user. KPI 9 reports weight of waste over 7 sub-categories: (9a) Waste to landfill; (9b) Waste to Recycling; (9c) Waste to incineration with energy recovery; (9d) Waste to incineration without energy recovery; (9e) Waste to composting; (9f) Waste to anaerobic digestion; (9g) Waste disposed by other routes, unspecified. Calculation: KPI 9a + KPI 9b + KPI 9c + KPI 9d + KPI 9e + KPI 9f + KPI 9g = KPI 9 (total weight of waste disposal) These KPIs can be investigated through the use of on-line chart generators, which reveal data about an organisation s properties of different types and in different countries. They can be used to prioritise action to improve the performance of individual buildings and of whole portfolios. Tailored annual reports for each member summarise their KPI data and highlight areas for action. * refers to section numbers from Best Practices Recommendations on Sustainability Reporting, September 2011 from EPRA. ** balance/concepts.htm *** Based on the definition of the OCED EU- Organisation for Economic Co-operation and Development.

14 14 Benchmarking Report 2013 ISA Example Benchmarks ISA now has three years worth of measurement data from around the world, which BRE has used to generate three sets of benchmarks. These apply to the three KPIs which are normalised by floor area and which can therefore be compared across buildings. Unlike portfolio average values, benchmarks have been calculated by removing both null (and zero) data and extreme values, and then computing an average across all the member properties of a given type in a given country. The resulting values can be accessed by members to benchmark their own buildings in a particular country or region, either as individual buildings or as whole portfolios. To date, the benchmarks cover two main property types offices and retail buildings and a total of 51 countries, for each of the three benchmark KPIs energy use, greenhouse gas emissions and water consumption. The figures on this page show examples of the sort of benchmark information produced and the range of values obtained across different countries. 182 Emissions Intensity (kg CO 2 e / year) Offices Asia Taiwan N.

18 18 Benchmarking Report 2013 The Future - Intended Developments and System Enhancements When ISA was first envisaged we set ourselves the task to deliver 9 KPIs relating to energy, GHG, water and waste to GRI CRESS / EPRA standards. Since then, the world has changed and we find that we need additional KPIs and reports for occupancy, temperature and transportation. Occupancy is already available within the ISA system but time of occupancy is not. We can therefore input data on the number of people within a building but not the time they are there. Once we develop a tool to do this, ISA members will be able to optimise their properties in a more cost effective manner. We have already begun some work in this area and found that cleaners were entering the building at 4am and leaving the lights on when they left at 6am. By amending the cleaning contract so that they arrived at 6 and left when the staff arrived at 8, we were able to demonstrate that significant energy savings could be made. The ISA online tool generates results the moment data has been added, so it is very easy to spot trends. The most important KPI to develop is GHG emissions from Transport. As of 1st September 2013, it became law in the UK for companies to report how their transport fleets measure against European standards. ISA already provides extensive reports on GHG emissions for buildings and we are currently working on an enhancement that will combine transport and building consumption data so that the requirements of UK legislation can be met. This KPI will be extended to encompass other countries GHG reporting standards in due course. ISA membership continues to expand as the requirement to have benchmarks backed by sound science provided by BRE are recognised. The ISA database is commercially sensitive so although data is collectively aggregated, the data and performance of an individual company is not disclosed. This has 2 benefits. It protects anonymity and it removes the incentive by members to manipulate their data to ensure a more favourable result. Our greatest growth area has been in Portfolio Membership where companies who want to become part of ISA but who may not wish to formally join can have their data entered by other members who add value through offering recommendations and additional comment. BRE Ltd can do this, as can Habitech in Italy and Switzerland, Bopro in Belgium and Luxembourg, Qatar GBC in Qatar, BRE Brazil in South America and Egis Conseil Bâtiment in France. There is a sound business case for this and we would encourage other companies who wish to participate to get in contact with us. Europa Galerie (ECE)
