GRESB + SIERA = Success
Sustainability data can be complex. It can show many interesting patterns and insightful trends about energy usage, but at the same time be hard to manage. The ability to use sustainability data to reduce energy usage by seeing the impact of actions is one of its most powerful features. Connecting those patterns and trends to actions leads to results.
GRESB provides a way of thinking about sustainability data which focuses effort on certain areas and types of energy consumption. SIERA is the sustainability software solution by EVORA for managing asset portfolio data to help achieve sustainability goals. SIERA provides a way of seeing those areas and types of energy consumption by organising consumption, meters, properties, and funds to make it easier to understand. That’s why EVORA sustainability consultants use it get the best out of the data, and easily see patterns which otherwise would be hidden.
But GRESB provides its own challenges. Submitting data to GRESB involves making sure the data is correct, accurate and above all reflects the performance of a property and ultimately a portfolio.
GRESB can be challenging to get right
For those who submit to GRESB, there’s a lot of data to prepare – a lot of ducks to get into rows if you will. One of the first hurdles is making sure that your asset data is correct, that floor areas add up correctly and that the consumption, waste or emissions make sense to GRESB. There’s wide range of categories and ownership to consider, and things like where emissions are generated and who consumes them.
In short, it can easily become somewhat of a mountain of information to organise. GRESB provide a website and a spreadsheet you can use to upload data. The website points out where things don’t add up correctly and you work through the errors until they’re all gone.
GRESB also provides the ability to use software to upload your data. This method is very similar to the website except errors are sent to the software instead of the GRESB webpage. SIERA uses this method to direct the wealth of asset data it contains about assets in the portfolios and funds managed by EVORA consultants.
This connection means SIERA can take advantage of its own intelligence to make it easier to prepare for GRESB.
SIERA makes things clearer
SIERA is a platform whose main aim is to make sustainability data more manageable and the intelligence within it easier to see. It shines at tasks like GRESB mainly because it already contains a lot of the data required for a GRESB submission. SIERA uses this data to show the patterns, monitor the impact of actions and to look for potential improvements.
SIERA has a wide range of different ways of showing the data, each taking a different slice of the data to show a pattern. Having so many different views on the data makes it much easier to understand the data which gets sent to GRESB.
Asset-level reporting becomes easy
This year GRESB changed how data is reported. Before it was fund-level, meaning the total consumption and usage of all assets in a fund was submitted. This year it became asset-level. This means the energy and performance of each individual asset is submitted. As you can imagine, this means much more detail is needed and a finer grain of accuracy than before.
Luckily for SIERA users this didn’t pose a problem. SIERA already recorded data at the meter level so this change didn’t cause a problem.
Qualitative survey answers add colour
GRESB doesn’t just focus on utility readings. It also asks a range of questions about the social initiatives, engagements and technical assessments done for each asset. This qualitative data helps to show how a building is being managed and what social programs are taking place to increase the sustainability of an asset.
SIERA captures this data using surveys. SIERA surveys capture exactly the qualitative data that GRESB asks about. Surveys can be sent out to building and property managers for each asset and contain a range of questions about the asset and its management.
SIERA automatically prepares the answers for the GRESB questions which focus on the building management. Where it can, SIERA also uses data it already has to save time for anyone submitting data to GRESB. For example, rather than ask every property manager if a building uses automatic meter readings, SIERA simply looks at the meters in the asset and checks itself.
No GRESB errors doesn’t always mean correct
Once the asset data has been checked for any updates, SIERA displays the whole GRESB submission in one page. This table makes errors or unexpected variances stand out so you can quickly correct any potential mistakes.
EVORA consultants use SIERA to prepare submissions for clients. On top of that, because they’re experts in their field, they use it to see where adjustments might be necessary.
GRESB show where data doesn’t add up using errors and outliers. This helps to make sure data like floor area coverage is correct, but it doesn’t highlight poorly organised data. EVORA consultants know to look for variances which may indicate problems like consumption data that has been incorrectly allocated to the wrong area of the building.
EVORA uses SIERA to achieve higher GRESB scores
Using these SIERA features make GRESB easier to get right, but they also make it easier to get higher scores. EVORA consultants use the fine-grain control of SIERA and the data visualisations and views to get the most out of the data, and correct issues before they get to GRESB.
Whilst other sustainability software can also prepare submissions for GRESB, SIERA ensures that the data is both in its best form, and used to get real results. Once the GRESB period is over EVORA consultants use the data to feedback to clients to help guide which actions will achieve an asset’s sustainability goals.
This combination of EVORA + SIERA explains how EVORA helped a number of our clients achieve GRESB global sector leadership and Hines Europe to achieve 100% in its Resilience score.
