How to read this document?

The GRESB Real Estate Scoring Document provides a visual breakdown of each indicator score included in the 2019 GRESB Real Estate Assessment. We recommend reading this document in conjunction with the Reference Guide which includes the reporting requirements of indicators.

This document includes:

Example: Indicator MA5

3 points , MP, G

This indicator is split into three sections represented by two fractions and an "x" in the far-left column. The first section addresses the predetermined consequences of performance targets, the second covers which employee group(s) do the ESG factors apply; the final section allows is for providing evidence. The far-left column tells us that the score of the indicator is calculated as follows; (where the section and evidence scores are all numbers between 0 and 1):

Indicator score = (consequences score + 1/2 * employee groups) * evidence score * 3 points

If the respondent achieved maximum scores for both of the first and second sections, with partially accepted evidence (resulting in a multiplier of 0.5), the score is:
min(1/2 + 1/2) * 0.5 * 3 points = 1.5 points

Management

Performance Indicators

The indicators in this Aspect are reported and scored separately for each property type. The total score of the Aspect is calculated by taking a weighted average of the scores per property type weighted by the GAV percentage allocated to each property type in RC5.1.

Energy Consumption Data

2018 Indicator

Not scored

12 points , IM, E

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The score of this indicator equals the sum of the scores achieved by:

  1. Data coverage = 8 points;
  2. Like-for-Like performance improvement = 2 points.
  3. Like-for-Like data availability = 0.5 points;
  4. Asset-level data reporting = 1.5 points;

Data coverage:

Data coverage percentages are calculated and scored separately against different benchmarks for landlord and tenant obtained data for each property type, where "landlord obtained" and "tenant obtained" are defined as:

  • Landlord obtained data:
    • Managed Assets: Base Building, Tenant Space purchased by Landlord, and Whole Building.
  • Tenant obtained data:
    • Managed Assets: Tenant space purchased by tenant;
    • Indirectly Managed Assets: Whole building.

Benchmarks are constructed by following the steps below:

  1. Check if there are at least 12 respondents with coverage percentages greater than 0% and less than 100% within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with coverage percentages greater 0% and less than 100% across regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, use static cut-off points of 25%, 50% and 75% to make the benchmark.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the coverage percentages between 0% and 100% into four intervals. The score achieved by a respondent depends on which interval their coverage percentage lands in, unless they had a coverage percentage of 0% or 100% in which case they will always receive a specfic score. The relationship between coverage percentages and scores is described in the table below:

Coverage percentage Fraction of maximum score
0%0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
[ b3,100% ] 4/4

The resulting scores are then aggregated to a single score using a weighted mean with weights determined by floor area, except for base building and tenant space for which base building has a static weight of 40% and tenant space has a static weight of 60%. As tenant space has both a landlord obtained and a tenant obtained section the 60% weight has to be shared between the two which is done based on relative floor area. If a respondent reports on both base building pluss tenant space and whole building, then base building pluss tenant space is given a weight based on floor area which is then split further based on the 40% - 60% weights.

Like-for-Like performance improvement:

Like-for-Like performance is scored based on the percentage change in consumption using a methodology identical to the scoring of data coverage, except for that having a lower value (for example a negative one) which ends up in a lower quartile will always result in a higher or equal score, and that scores are aggregated using Like-for-Like consumption in the previous year as weights instead of area. If the GRESB reporting universe does not contain a sufficient number of peers to construct a global benchmark (minimum of 12), the benchmark will use a static model with cut off points at: -5%, -2.5% and 0%.

We will refer to the three benchmark numbers b1, b2 and b3 where b1 < b2 < b3. These will be used to split the LFL percentage changes into four intervals. As for data coverage the score achieved by a respondent depends on which interval their LFL percentage change lands in, but how many points are given for each interval depends on the relationship between the mean, median and 0 percentage change. Which percentage change results in which score depending on the different relationships between the mean, median and 0 percentage change are described in the tables below:

If 0 < mean & median < mean:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< mean 2/3
b2 =< LFLpc < b3 & LFLpc =< mean 1/3
b3 =< LFLpc or LFLpc > mean 0/3
If mean =< 0:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< 0 2/3
b2 =< LFLpc < b3 & LFLpc =< 0 1/3
b3 =< LFLpc or LFLpc > 0 0/3
If 0 < mean =< median:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< mean 2/3
b2 =< LFLpc or LFLpc > mean 0/3

Like-for-Like data availability:

Points for Like-for-Like data availability are given if any Like-for-Like data is provided and not excluded in the GRESB outlier check.

Note: data reported for the outdoor area is included in the Like-for-Like scoring and outlier check but excluded from the data coverage scoring.

Asset-level data reporting:

Points relating to asset-level data reporting are granted if participants report their energy consumption values at asset-level.

Open text box: The content of this open text box is not used for scoring, but will be included in the Benchmark Report.

Outlier checks:

GRESB performs two outlier checks for the data provided in this indicator, one based on the energy consumption intensity per square meter and one based on the percentage change in like-for-like consumption.

Intensity outliers:

For intensities, GRESB checks whether the reported values result in an intensity outside a range of expected values. If the value is outside that range, then the respondent is requested to provide an explanation for why their data is abnormal and this explanation is then checked in combination with statistics on the distribution of intensities for the same property type. If the explanation is not accepted, then the respondent will be scored as if they didn't provide the data associated with the explanation.

Like-for-like outliers:

For like-for-like changes, GRESB checks whether the provided values result in absolute percentage changes greater than a threshold between 10% and 20% depending on the like-for-like values reported for the previous year. Higher values result in a lower threshold for what is deemed abnormal. As for intensities, if an outlier is flagged the respondent is prompted to explain the abnormal value and the explanation is then checked in combination with statistics on like-for-like changes for the given property type. Data associated with explanations which are not accepted are treated as if they were not provided for all scoring purposes.

1.5 points , IM, E

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The scoring of this indicator is the sum of the scores achieved by:

  1. Reporting intensity data for the current reporting year;
  2. Number of selected intensity normalization factor.
    • Other: 'Other' answer must be accepted during validation to achieve a score.

    • The checkbox "None of the above" is not scored.

3 points , IM, E

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The scoring of this indicator is split into two parts. The first part can result in a maximum of 2/3 of the maximum score. This is achieved if any on-site renewable energy was generated in the current year. If this is not the case, but some off-site renewable energy was generated in the current year, then 1/3 of the maximum score is achieved instead.

The remaining 1/3 of the maximum score is given based on the percentage renewable energy in the current year and the improvement compared to the previous year. These two elements are combined using the following formula, where p is the percentage renewable energy and i is the improvement score:

Score = (100 + p) / 200 * p / 100 + (100 - p) / 200 * i

The improvement score is calculated based on the improvement in the percentage renewable energy compared to the previous year, if there was one. The improvement is compared against a benchmark based on the improvements of other respondents which is constructed by following the steps below:

  1. Check if there are at least 12 respondents with improvements (changes greater than 0%) within the same property type and region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with improvements within the property type across all regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, check if there are at least 12 respondents with improvements across all property types within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  4. If the step above failed, make the benchmark the quartiles of the distribution of the percentage improvements across all regions and property types.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the improvement percentages into four intervals. The score achieved by a respondent depends on which interval their improvement percentage lands in. The relationship between improvement percentages and scores is described in the table below:

Improvement percentage Fraction of maximum score
<= 0% 0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
>= b3 4/4

3.5 points , IM, E

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The score of this indicator equals the sum of the scores achieved by:

  1. Data coverage = 2 points;
  2. Like-for-Like performance improvement = 1 points.
  3. Asset-level data reporting = 0.5 points;

Data coverage:

Data coverage percentages are calculated and scored separately against different benchmarks for scope 1, 2 and 3.

Benchmarks are constructed by following the steps below:

  1. Check if there are at least 12 respondents with coverage percentages greater than 0% and less than 100% within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with coverage percentages greater 0% and less than 100% across regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, use static cut-off points of 25%, 50% and 75% to make the benchmark.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the coverage percentages between 0% and 100% into four intervals. The score achieved by a respondent depends on which interval their coverage percentage lands in, unless they had a coverage percentage of 0% or 100% in which case they will always receive a specfic score. The relationship between coverage percentages and scores is described in the table below:

Coverage percentage Fraction of maximum score
0%0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
[ b3,100% ] 4/4

The resulting scores for each scope are aggregated to a single score using a weighted mean using the maximum data coverages as weights.

Like-for-Like performance improvement:

Like-for-Like performance is scored based on the percentage change in consumption using a methodology identical to the scoring of data coverage, except for that having a lower value (for example a negative one) which ends up in a lower quartile will always result in a higher or equal score, and that scores are aggregated using Like-for-Like consumption in the previous year as weights instead of area. If the GRESB reporting universe does not contain a sufficient number of peers to construct a global benchmark (minimum of 12), the benchmark will use a static model with cut off points at: -5%, -2.5% and 0%.

We will refer to the three benchmark numbers b1, b2 and b3 where b1 < b2 < b3. These will be used to split the LFL percentage changes into four intervals. As for data coverage the score achieved by a respondent depends on which interval their LFL percentage change lands in, but how many points are given for each interval depends on the relationship between the mean, median and 0 percentage change. Which percentage change results in which score depending on the different relationships between the mean, median and 0 percentage change are described in the tables below:

If 0 < mean & median < mean:
Condition Score
LFLpc < b1 3/3

Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< mean 2/3
b2 =< LFLpc or LFLpc > mean 0/3

Asset-level data reporting:

Points relating to the asset-level data reporting are granted if participants report their GHG emissions at asset-level.

Open text box: The content of this open text box is not used for scoring, but will be included in the Benchmark Report.

Outlier checks:

GRESB performs two outlier checks for the data provided in this indicator, one based on the GHG emissions intensity per square meter and one based on the percentage change in like-for-like consumption.

Intensity outliers:

For intensities, GRESB checks whether the reported values result in an intensity outside a range of expected values. If the value is outside that range, then the respondent is requested to provide an explanation for why their data is abnormal and this explanation is then checked in combination with statistics on the distribution of intensities for the same property type. If the explanation is not accepted, then the respondent will be scored as if they didn't provide the data associated with the explanation.

Like-for-like outliers:

For like-for-like changes, GRESB checks whether the provided values result in absolute percentage changes greater than a threshold between 10% and 20% depending on the like-for-like values reported for the previous year. Higher values result in a lower threshold for what is deemed abnormal. As for intensities, if an outlier is flagged the respondent is prompted to explain the abnormal value and the explanation is then checked in combination with statistics on like-for-like changes for the given property type. Data associated with explanations which are not accepted are treated as if they were not provided for all scoring purposes.

  1. Check if there are at least 12 respondents with coverage percentages greater than 0% and less than 100% within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with coverage percentages greater 0% and less than 100% across regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, use static cut-off points of 25%, 50% and 75% to make the benchmark.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the coverage percentages between 0% and 100% into four intervals. The score achieved by a respondent depends on which interval their coverage percentage lands in, unless they had a coverage percentage of 0% or 100% in which case they will always receive a specfic score. The relationship between coverage percentages and scores is described in the table below:

Coverage percentage Fraction of maximum score
0%0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
[ b3,100% ] 4/4

The resulting scores are then aggregated to a single score using a weighted mean with weights determined by floor area, except for base building and tenant space for which base building has a static weight of 40% and tenant space has a static weight of 60%. As tenant space has both a landlord obtained and a tenant obtained section the 60% weight has to be shared between the two which is done based on relative floor area. If a respondent reports on both base building pluss tenant space and whole building, then base building pluss tenant space is given a weight based on floor area which is then split further based on the 40% - 60% weights.

Like-for-Like performance improvement:

Like-for-Like performance is scored based on the percentage change in consumption using a methodology identical to the scoring of data coverage, except for that having a lower value (for example a negative one) which ends up in a lower quartile will always result in a higher or equal score, and that scores are aggregated using Like-for-Like consumption in the previous year as weights instead of area. If the GRESB reporting universe does not contain a sufficient number of peers to construct a global benchmark (minimum of 12), the benchmark will use a static model with cut off points at: -5%, -2.5% and 0%.

We will refer to the three benchmark numbers b1, b2 and b3 where b1 < b2 < b3. These will be used to split the LFL percentage changes into four intervals. As for data coverage the score achieved by a respondent depends on which interval their LFL percentage change lands in, but how many points are given for each interval depends on the relationship between the mean, median and 0 percentage change. Which percentage change results in which score depending on the different relationships between the mean, median and 0 percentage change are described in the tables below:

If 0 < mean & median < mean:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< mean 2/3
b2 =< LFLpc < b3 & LFLpc =< mean 1/3
b3 =< LFLpc or LFLpc > mean 0/3
If mean =< 0:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< 0 2/3
b2 =< LFLpc < b3 & LFLpc =< 0 1/3
b3 =< LFLpc or LFLpc > 0 0/3
If 0 < mean =< median:
Condition Score
LFLpc < b1 3/3
b1 =< LFLpc < b2 & LFLpc =< mean 2/3
b2 =< LFLpc or LFLpc > mean 0/3

Asset-level data reporting:

Points relating to the asset-level data reporting are granted if participants report their water consumption values at asset-level.

Open text box: The content of this open text box is not used for scoring, but will be included in the Benchmark Report.

Outlier checks:

GRESB performs two outlier checks for the data provided in this indicator, one based on the water consumption intensity per square meter and one based on the percentage change in like-for-like consumption.

Intensity outliers:

For intensities, GRESB checks whether the reported values result in an intensity outside a range of expected values. If the value is outside that range, then the respondent is requested to provide an explanation for why their data is abnormal and this explanation is then checked in combination with statistics on the distribution of intensities for the same property type. If the explanation is not accepted, then the respondent will be scored as if they didn't provide the data associated with the explanation.

Like-for-like outliers:

For like-for-like changes, GRESB checks whether the provided values result in absolute percentage changes greater than a threshold between 10% and 20% depending on the like-for-like values reported for the previous year. Higher values result in a lower threshold for what is deemed abnormal. As for intensities, if an outlier is flagged the respondent is prompted to explain the abnormal value and the explanation is then checked in combination with statistics on like-for-like changes for the given property type. Data associated with explanations which are not accepted are treated as if they were not provided for all scoring purposes.

    • The checkbox "None of the above" is not scored.

0.5 points , IM, E

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The scoring of this indicator is split into two parts. The first part can result in a maximum of 2/3 of the maximum score. This is achieved if any on-site water reuse and recycling data is enerated for the current year.

The remaining 1/3 of the maximum score is given based on the percentage reused and recycled water in the current year and the improvement compared to the previous year. These two elements are combined using the following formula, where p is the percentage reused and recycled water and i is the improvement score:

Score = (100 + p) / 200 * p / 100 + (100 - p) / 200 * i

The improvement score is calculated based on the improvement in the percentage reused and recycled water compared to the previous year, if there was one. The improvement is compared against a benchmark based on the improvements of other respondents which is constructed by following the steps below:

  1. Check if there are at least 12 respondents with improvements (changes greater than 0%) within the same property type and region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with improvements within the property type across all regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, check if there are at least 12 respondents with improvements across all property types within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  4. If the step above failed, make the benchmark the quartiles of the distribution of the percentage improvements across all regions and property types.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the improvement percentages into four intervals. The score achieved by a respondent depends on which interval their improvement percentage lands in. The relationship between improvement percentages and scores is described in the table below:

Improvement percentage Fraction of maximum score

This indicator is answered separately for each property type. These answers are also scored per property type, resulting in multiple scores for the same indicator. Scores are aggregated across property types by taking a weighted mean of the property type scores, weighted by the percentage of GAV reported for each property type in RC5.1.

The score of this indicator equals the sum of the scores achieved by:

  1. Data coverage = 1.5 points;
  2. Proportion of waste diverted = 1.5 points.
  3. Asset-level data reporting = 0.25 points;

Data coverage:

Data coverage percentages for the current year are scored sepataly against different benchmarks for directly and indirectly managed assets for each property type.

Benchmarks are constructed by following the steps below:

  1. Check if there are at least 12 respondents with coverage percentages greater than 0% and less than 100% within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with coverage percentages greater 0% and less than 100% across regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, use static cut-off points of 25%, 50% and 75% to make the benchmark.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the coverage percentages between 0% and 100% into four intervals. The score achieved by a respondent depends on which interval their coverage percentage lands in, unless they had a coverage percentage of 0% or 100% in which case they will always receive a specfic score. The relationship between coverage percentages and scores is described in the table below:

Coverage percentage Fraction of maximum score
0%0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
[ b3,100% ] 4/4

The resulting scores are then aggregated to a single score using a weighted mean with weights determined by the reported percentage of indirectly managed area from RC5.1.

Proportion of waste diverted:

The percetange of waste diverted (total) for the current reporting year is scored the same way as data coverage, except that there is only one benchmark and one score for each property type as this number is not reported separately for directly and indirectly managed assets.

Asset-level data reporting:

Points relating to the asset-level data reporting are granted if participants report their waste consumption values at asset-level.

Open text box: The content of this open text box is not used for scoring, but will be included in the Benchmark Report.

Outlier checks:

For this indicator we only do an outlier check based on the waste generation intensity per square meter.

For intensities, GRESB checks whether the reported values result in an intensity outside a range of expected values. If the value is outside that range, then the respondent is requested to provide an explanation for why their data is abnormal and this explanation is then checked in combination with statistics on the distribution of intensities for the same property type. If the explanation is not accepted, then the respondent will be scored as if they didn't provide the data associated with the explanation.

Each certification is validated by GRESB according to a list of predifined criteria which results in a weight as shown in the table below:

Validation status Weight
Full points 1.0
Partial plus 0.6
Partial minus 0.3
No points 0.0

The overall portfolio coverage of building certification of this indicator is the sum of weighted coverage percentages of each reported certification scheme. The overall portfolio coverage number is benchmarked.

Benchmarks are constructed by following the steps below:

  1. Check if there are at least 12 respondents with coverage percentages greater than 0% and less than 100% within the same region. If so, make the benchmark the quartiles of the distribution of these percentages.
  2. If the step above failed, check if there are at least 12 respondents with coverage percentages greater 0% and less than 100% across regions. If so, make the benchmark the quartiles of the distribution of these percentages.
  3. If the step above failed, use static cut-off points of 25%, 50% and 75% to make the benchmark.

Referring to the three benchmark numbers as b1, b2 and b3 where b1 < b2 < b3, these numbers are used to split the coverage percentages between 0% and 100% into four intervals. The score achieved by a respondent depends on which interval their coverage percentage lands in, unless they had a coverage percentage of 0% or 100% in which case they will always receive a specfic score. The relationship between coverage percentages and scores is described in the table below:

Coverage percentage Fraction of maximum score
0%0/4
< 0%,b1 > 1/4
[ b1,b2 > 2/4
[ b2,b3 > 3/4
[ b3,100% ] 4/4

Note that the benchmark is constructed using data from both Real Estate and Developer assessment respondents.
