ES-SDA Solar Shading Products DatabaseWhy do we need it?

Credibility of shading properties information

regulation and profession

• EPBD requirements compliance and quality: ES-SDA as best case in EU-Qualicheck

• Education of profession (shading and building developers)

Longer term objectives

• Development of International reliable Database

• Cloud based calculation tool

• Complex modelling but simple to use

The issue with compliant data in EPB

Low appreciation of solar shading in EPB calculation

• Presentation of shading properties performance vary widely

• Questions about reliability of data

Conservative approach of the regulator

Shading in national EPB calculation methodologies

Country Shading in EPB Methodology

Austria Prevention of overheating Fc = 0.15/0.25/0.5 or 13363 g-value

Belgium Prevention of overheating Fc = 0.50/0.60/0.9 or accredited value

Denmark yes Actual g-value, automatic/manual

Finland yes

France detailed At least 24 actual values, aut./man. …

Germany yes, DIN 4108-2, 18599 Actual Fc value

Greece

Hungary Prevention of overheating

Ireland no

Italy Yes, UNI 11300 (13790) Actual g-value, ext.

Malta yes

Shading in national calculation methodologies

Country Shading in BC or EPB Methodology

Netherlands Yes, NEN 7120 (13790) Ext: Fc = 0.3

Norway Yes

Poland Yes Default values

Portugal Yes

Spain Yes Actual g-value

Sweden No (no EPB calculation) Dynamic Simulation

Switzerland Yes

UK Yes Default g-values

Shading is European mature technology, but

No harmonised data

Default values often far from actual values

How to get a reliable database

• Product values measured or calculated according to standardized methods

• Testing in independent labs with calibrated instruments according to Standards

• Verification of the data by experts

• Database based on WIS

• Submission by manufacturers (fabric/materials and finished products)

• Peer Review Procedure

Only a validation of data

• Not a search tool to “compare” manufacturers’ product or to find the “best performing” product

Design based on the Glazing database WIS

• Manufacturer submits tested data

• Samples of material with submission

Procedure steps

• Web tool for data submission Manufacturer (material/product)

• Optical data and Product ID data
