The role of standards and guidelines to improve significantly energy efficiency

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!

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

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?)

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
