The policy background

High efficiency
Low efficiency
Reduce consumption!
EU’s 2020 objective:
All new/refurbished buildings asNZEBs (Nearly Zero Energy Buildings)

Quality renovation...achieved with the Passive House principles
Is it worth?Heating demand reduction = - 1 kWh/(m².a)
Needed here to reach EnerPHit
Investment ~ 40 €/m²TFA
Negative Net Present Value, but…
Cheaper than insulate slabs from the inside!

Total annual cost
Here EnerPHit can be reached without additional total cost
White certificates : - 3% to -10% investment in opaque components
Assessment on 20 years + Residual values on extra 10 years

Couple interventions when ripe
Windows+Walls or Walls before Windows?
Windows+Walls:Take out window+shutter
= 190 €/window
Lost residual value
~ 100 €/window
Install new window+shutter
= 1250 €/window
Walls before Windows:Invest = 300 €/window

Innovative window installation
Prefabricated window installation with
aerogel and cork• Thought for interior insulation of listed
buildings, step-by-step possible
• 745 €/m² (excl. VAT) installed
• Ψinstalled,lateral=0.06 W/(m.K)
• Ψinstalled,bottom=0.03 W/(m.K)

Step-by-step window connection
Manufacturer competition (Component Award, 2015)• Change windows first
• Insulate walls 10 years after (exterior insulation)
• Half of solutions with windows staying in place
www.europhit.eu
Cascade ventilation
• Supply air in bedrooms (20 m3/h each), living room (60 m3/h)
• Transfer vent from living room to kitchen
• Cellar: 10 m3/h supply air to minimize duct length
• Extract (existing) in kitchen, bathroom and WC, total 120 m3/h / 0,5 h-1
Reuse existing extract ducts
• Total investment: 8.6 k€/dwelling
Expanded cascade ventilation?
• Can we delete the air inlet in the living room?
• Can we blow fresh air from the corridor?

Cascade ventilation
Expanded cascade ventilation• Air quality would be too low here if no supply air in living room
• Works better if bedrooms have direct link to living room

Air/Water Heat Pump on extract air
A suitable solution for EnerPHit ?
• Outdoor unit 20 kW, Hydraulic modules with 150 L storage in cellars
• Outdoor air pre-heating via air/water heat exchanger
and variable flow from damper and small fan CO2-regulated
• Heating demand 20 kWh/(m².a)
• Primary energy demand 115 kWh/(m².a)

Make ventilation cheaper
Atrea Duplex RS4
• 900 m3/h Air Handling Unit with 90% heat recovery, air heating and cooling
• suitable for decentralised ventilation of refurbished offices
• Average price 2000€/unit

Conclusion
Overall Refurbishment Plan• Upgrade existing plan with EnerPHit quality is possible: budget shifts towards envelope
• Identify intermediate states
• Check quality via certification process
Prove cost-efficiency• PHPP9 Variants and Comparison Worksheets
• Capital cost up to 90% of total cost for EnerPHit
Reduce costs• Reproductible solutions
• Cascade ventilation
• New products which make EnerPHit easier : window connection, window+ventilation
• Financial support for design, quality insurance and product development
