Concept: @Andrea Moro

✓Impact the evaluation of local policies & contribution towards global goals

✓Connect the Local-Regional-National-EU-World levels

✓ Have a COMMON LANGUAGE to understand each other

✓ Support COMMON PERCEPTION of key sustainability issues

✓ Set reliable, measurable & verifiable PERFORMANCE TARGETS, based on quantitativeindicators

✓ MONITOR PROGRESS towards common sustainability objectives

✓ Facilitate TRANSFERRING of BEST PRACTICES; learning from each other

✓ Develop a MULTISCALE (Building & Urban) & MULTICRITERIA (all sustainability issues)ASSESSMENT TOOL to support DECISION MAKING PROCESSES

✓ Improve the effectiveness of policies, action plans, planning

✓ CONTEXTUALIZE assessment & rating to LOCAL PRIORITIES

✓ Fit public administrations’ needs (lower cost)

✓ SENSE OF LOCAL OWNERSHIP; Flexibility to adapt to local needs & priorities

Harmonized Sustainability Assessment System WHY ?



6

Harmonized Sustainability Assessment System WHAT ?

Develop the first

Transnational multicriteria assessment system for rating the sustainability of

✓ Buildings

✓ Neighbourhoods

Associated to a

Decision making process

✓ Select the best sustainability retrofit strategies

✓ Increase the quality of public buildings & neighbourhoods

Large scale

✓ Synergies✓ Sustainable solutions

✓ Opportunities➢ Challenges - Complexities

Identify the main Issues that are important for assessing the sustainability of buildings & neighborhoods

Describe specific aspects of an issue that group relevant criteria & indicators

Describe the specific aspects of a category and represent the main assessment entries used to characterize an urban area or building, from the very beginning of the assessment process

Quantify the performance with respect to each criterion. For simplicity, only one indicator is associated with each criterion. The metrics are used to quantify the performance and determine how well the sustainability objectives are achieved; Quantitative and some times qualitative criteria are used

Examples:

Issue: ‘Energy’ ⬧ Category: ‘Non-Renewable Energy Sources’ ⬧ Criterion: ‘Building Thermal Energy Use’ ⬧ Indicator: ‘kWh/m2’

Issue: ‘Social Aspects’ ⬧ Category: ‘Traffic & Mobility Services’ ⬧ Criterion: ‘Pedestrian Streets & Bicycle Paths’ ⬧ Indicator: ‘m/ resident’

Issue: ‘Economy’ ⬧ Category: ‘Economic Activity’ ⬧ Criterion: ‘Employment’ ⬧ Indicator: ‘% Employment rate of residents’

➢ Benchmarking & Scoring Scale• Handle diversity of indicators

(e.g. different units & orders of magnitude, or associated with qualitative criteria – no units)

• Adopt to local conditions (e.g. climate, building practice, standards, advancement in sustainability issues)

➢ PASSPORT• Depository of KPI data and relevant

information for Buildings & Neighborhoods • Compare performance at transnational level

✓ Based on common KPIs & metrics✓ Common calculation method✓ Allow consistent comparison

THE TOOL

➢ Generic Framework for the Region, Municipality (GF-U) or the Building (GF-B)Adapted later according to the local policies, priorities, issues for specific projects (e.g. different neighborhoods, scenarios)

➢ STEP 1Set the priorities for each of the 7 IssuesAssign Weighting Factors for each Issue(from 1 to 3 most important )



14

THE TOOL

16 KPIs(mandatory)

N.A. Not selected indicators

➢ STEP 2Select relevant indicators to include in the project; 16 KPIs are mandatory
