Energy sustainability: EC policies and concrete studies

Dr. Harald Schönberger / Dr. Jose Luis Galvez Martos

Conference “Boosting Renewable Energy Supply and In-Store Energy Efficiency”


OUTLINE

1. The Policy Context of energy efficiency and environmental performance of retailers

2. The Improvement Potential of the energy performance of retailers

3. The Reference Document on best environmental management practice of the retail trade sector

4. Options to reduce the energy demand

5. Options to be more energy efficient

6. Options to use better energy sources

POLICY CONTEXT

All the policy instruments identify retailers as the activity with high influence on consumers

Therefore, retailers are essential for the implementation of many environmental initiatives, regulations or directives, for example:

• Offer of Ecolabeled products

• Waste policy: WEEE, National plans,etc.

• Choice editing of energy efficient equipment, mandatory (e.g. ecodesign) or voluntary

•…


POLICY CONTEXT

All the policy instruments identify retailers as the activity with high influence on consumers

As well, many initiatives are driven for / byretailers:

• Retail Forum

• European Food SCP Round Table

• Priority sector for the development of Reference Document on Best Environmental Management Practice under EMAS regulation (but going beyond EMAS)


IMPROVEMENT POTENTIALBrussels 30 March 2011 – Workshop: EMAS pilot reference document on BEMP in the construction sector 6

THE REFERENCE DOCUMENT

-Collects best environmental management practice of the sector (What can be done?)

-Covers the whole chain under the umbrella of EMAS but not only for EMAS (For everybody)

- Proposes indicators and benchmarks of excellence (Which is the achievable performance?)

Lighting, …Refrigeration

HVAC


OPTIONS TO REDUCE THE DEMAND

BUILDING

Envelope(ground floor, walls, roof, windows, doors)

Improved Insulation of walls (20 cm)

Exhaust air heat recovery Under demand control

Retrofitting of roofs (30 cm)

Heating, Ventilation and Air Conditioning (HVAC)


WASTE HEAT RECOVERY-Heat recovery from refrigeration will:

-Reduce the fossil fuel demand-If the building envelope is well insulated, there would be no need for a heating system-Net, saleable heat is produced under certain circumstances
