DEG – Resource and Efficiency Checks

Industrial companies with energy cost > 1 Mio USD/year

focus: production facilities and energy provision

All Agribusiness companies

focus: agricultural activities and food processing

Service sector (hotels, mall, etc.) with energy > 7% of overall cost

focus: AC, lighting, building management,

renewables


Advisory Portfolio for Agribusiness Biomass resource management

Biomass collection, confectioning and logistics Biomass-to-energy (heat, steam, cold, electricity) Biomass-to-soil (Biochar, Terra Preta)

1st Step: Assessment/Evaluation of single cross over technologies

2cd Step: Systemic & regional optimisation based on ZE/CE

New regional MFM strategies and cooperation


Electricity | High Efficiency Pumps and Motors


Replacement of (old) over-dimensioned pumps by high efficiency pumps Additional savings with frequency inverter possible

OLD Pump NEW Pump [Unit] Installed capacity 90,00 50,00 kW

Operating hours 3.550,00 3.550,00 h/a

Electricity demand 319.500,00 177.500,00 kWh/a

Electricity price 0,13 0,13 EUR/kWh

Electricity expenses 41.535,00 23.075,00 EUR/a

Monetary savings 18.460,00 EUR/a

Investment New Pump-Set 35.000,00 EUR

Static PBP 1,90 a

Electricity | High Efficiency Pumps and Motors


Electricity | Efficiency in illumination

LED-lamp (LED = light-emitting diode) Substitutes halogen spotlights (indoor) Substitutes HQL- and NAV- lamps (outside) Possible energy savings of up to 80 % Advantages: Long lifetime, dimmable, free choice of

colour, non-toxic, etc.


Electricity | Efficiency in illumination

Illumination planning Place and luminosity demand


Reduction of power capacity demand of 130kW Power demand old 167kW and 37kW new

Tremendous saving potentials: Annual electricity savings: 483,500 kWh Annual cost savings: 67,600 USD Annual GHG abatement: 18,373 kg CO2

Initial Investment: 108,200 USD

Average payback period: 1,6 years Cost savings over life time: 878,000 USD

Electricity | Efficiency in illumination – One Company


Electricity | Illumination – Economic valuation

Determination of LCOE (averaged electricity price) Inclusion of electrical work price (kWh) Inclusion of capacity price (kW) Based on applicable tariff

Capacity price is driving force! Perfect for load shifting!


Heat & Cooling | Insulation of Pipes and Armatures


Thermal Energy Efficiency | Air Handling Units

1st Area: Efficiency in Thermal Energy Production Production of Cold Energy - Chiller Production of Heat (Steam, …) Energy – Boiler

2st Area: Efficiency in HVAC (Distribution) Efficiency of up to 50% in Cold production/dissemination Efficiency of up to 60% in Cold production/dissemination


AHU | Extrapolation of Example result

Example of 5* Hotel with GFA of 60.000sqm Installed heat load (boiler capacity)

Installed heating load – old – 7.082 kW Extrapolated new heating capacity: 2.478 kW Reduction potential of 4.604 kW

Installed cooling load (chiller capacity 4.575 kW) Installed cooling capacity AHUs – old – 5.842 kW Extrapolated new cooling capacity: 3.067 kW Reduction potential of 2.775 kW

Payback period of 2.2 (incl. capacity) to 3.6 (kWh only) Annual GHG abatement potential of 550t COe2qu.
