AVL List GmbH

Parkgarage 1500 m²

With more than 11,500 employees, AVL L List t GmbH bH is the world's largest independent company for the development, simulation and testing of all types of powertrain systems (hybrid, combustion engine, transmission, electric drive, batteries, fuel cell and control technology), their integration into the vehicle and is increasingly taking on new tasks in the field of assisted and autonomous driving as well as data intelligence. Our ur Vision ion and Mission ion

• Clean. Affordable. Connected. Intelligent.

We as AVL provide leading technologies and superior services to our customers to create a better world by driving mobility trends of tomorrow.

Solar project Phase I

Parkgarage 1500 m²

Targe rgets ts

• Reducing consumption of Heat

sourcing from Natural Gas at cost below district heating

• Having a roof on the parking garage

preventing snow and heat impact

• Need for Storage tank to balance

solar energy between supply and demand

Solution

• The 1584 m² solar thermal plant

provides heat for conditioning regulators and building’s heating systems

• ESCO- Investor Solar.Nahwaerme.-

energiecontracting GmbH

• Installed capacity: 1100 kW nominal
• Solar yield: 550 MWh/year
• Ca. 240t of CO2 savings

per year.

• Commissioning: 2017

Benefits Phase I

• Reducing consumption of Heat sourcing from Natural

Gas at cost below district heating

• Having a roof on the parking garage preventing snow and

heat impact

• Limitation by summer demand on heat

Is Is th this is al all so solar ar in indu dustr stry ca y can do? n do?

Further Options and Demands

• Many more roofs
• Potential use of waste Heat
• Strong increasing need of Cooling
• Need of redundancy in the cooling

Smart integration- solution

• Many more roofs

➔ 2043 m² more solar

• Potential use of waste Heat

➔ using solar storage

• Strong increasing need of Cooling

➔ adding an AHP

• Need of redundancy in the cooling

Smart system integration advantages

THERMAL DRIVEN COOLING PROCESS

• Renewable Heat

Generation

• Redundancy
• Peak load reduction electric

demand

• Using Solar and Waste to

power cooling

HEAT

COLD WATER CONDITIONED AIR

• Peak

reduction from District Heating

• Energy

Efficiency

• Extended solar

potential by integration of Cooling & Heating

Examples in District Heating

• Biomas
• mass

s dist strict rict heati ting ng with h solar ar & storage

• rage
• Storage is used as well for peak load

management in winter from boiler

Examples in building sector

• Combin

mbined ed solar ar hot water er, , Cooling

• ling and heati

ting g for large ge buildings (Hospitals, Campus, …)

• On sunny days with cooling demand, the sun powers both AC

and hot water (summer/hot countries)

• On overcast days, the system

still delivers all needed hot water (100%) but cooling demand is a lot less to zero

• Heating in shoulder seasons/

winter

Summary

• To establis

ablish a new heat t syst stem em, , we need much more re than only y heat t generati eration

• n
• We need storage as central part (hourly, daily, seasonal)
• We need load management
• We need integration with cooling and heating
• We need integration of other variable heat sources

And then n solar ar heat t can play a major

• r role with

th its s advantages tages as

• ne of the cheapest
