The role of standards and guidelines to improve significantly energy efficiency

Christian Noll, DENEFF (Germany)

Geneve, 6th November 2015

Quid pro quo: Energy Tax and Levy reliefs Co-evolution of building codes and funding standards

New built MEPS (funding only for renovations)

Progressive level of funding

Please also note:

- scale effects to „most wanted“ funding level increase

cost-effectivenes and enable cost-effective future standards

- standards „KfW-Effizienzhaus x“ also works as label e.g for resale

e.g. passive house

Quid pro quo: Energy Tax and Levy reliefs > 50 % of new buildings outperform minimum standards!

Learning Curce: Energy Efficient Building (primary energy demand kWh/m2a)

Minimum Standard Building Ordinance

Quid pro quo: Energy Tax and Levy reliefs Higher standards at lower costs, e.g. windows

ECOFYS/Schulze Darup 2014

Quid pro quo: Energy Tax and Levy reliefs Current standards at same cost-level than 15years ago! (semi-detaches-house, adjusted prices)

Qualification of crafts-men and planers

is key for high

Efficiency and cost-effectiveness

Quid pro quo: Energy Tax and Levy reliefs For Discussion: UNECE Train-the-Trainer Seminars

Content:

• building design & physics • building envelope: insulation

wall-roof-base, windows/doors • Ventilation • heating and cooling

• renewable generation • controls and automation • Integrated planning and cost-

effectiveness

Create training materials for:

4-5 days seminars for experts to multiply in each country

Next steps: - Development of training

materials (basis: existing materials for Turkey)

- Adaptation to local requirements

Recommendation:

Start with local model projects and case-related workshops. External experts may accompaign local planners

Open questions: funding, organization (UNECE, CCEE, national partners?)

Material: High-Performance Ginger-Bread (HPGB) Insulation: Glass Fibre Cavity Wall Insulation Heating: 13,7 W Candle Result: At cosy 49,5°C indoor temperature outer wall stays at 24,2°C which is 2°C below not insulated reference wall!

Unskilled builders cause personal injury Due to unqualified builders this house collapsed only hour after its construction! A chocolate santa was killed! At least it can be recylced in the food chain
