SOLANOVA - The Project

• SOLANOVA
• Solar-supported, integrated eco-efficient
  renovation of large residential buildings and
  heat-supply-systems

2
SOLANOVA - Situation 1

• huge stock of old-style multi-flat buildings
  (Hungary 600,000 flats) needs to be restored in
  a sustainable way to avoid a "lost-opportunity"
  for another 30-50 years
• current renovations only result in minimal
  savings

3
SOLANOVA - Situation 2

• very low energy prices do not reflect real market
  conditions
• therefore many occupants in energy wasting flats
  will suffer from real prices in the near future
• companies waiting for enormous potential of
  implementing renovation measures

4
SOLANOVA - Objectives

• Making ongoing renovation sustainable
• restructuring large panel buildings to
  passive-houses or ultra-low-energy-houses (15 to
  45 kWh/m2a)
• trigger renovation of one selected building to
  this level
• to show large potential for solar energy for
  heating (cooling) and hot water by installing
  solar thermal panels
• investigation of change of inhabitants social
  situation (comfort, health, financial situation)
• middle-term renovation of whole residential
  quarter
• to serve as example for all similar quarters in
  Hungary
• strong focus on teaching and disseminating the
  results

SOLANOVA - Demo Building

• The most probable building
• Located in Dunaújváros
• Cooperation with Intercisa Housing Association

6
Project idea SOLANOVA

• Retrofit from bad state to passive house standard

7
SOLANOVA - Dissemination of Results

• Dissemination actions
• Website with online monitoring
• possibility for companies to advertise on website
• demo- and education centre in the building
• development of training materials (software and
  written material)
• training courses for various interested groups
• concepts for renovation contracting
• international conference, press articles, public
  relations
• influence on Hungarian building laws

SOLANOVA - The Consortium

• Hungary
• Budapest University of Technology and Economics
• Fiorentini (Solar)
• District Heating Company and Sziget Office,
  Dunaujvaros
• Energy Centre
• Austria
• Internorm (Windows)
• Germany

9
What qualifies a passive house

• No conventional heating system
• Extremely reduced heat losses
• Super insulation of walls, roofs ... (20-30 cm)
• Super glazing (u lt 0.8 W/(m2K)
• Controlled ventilation
• Maximum heating power 10 W/m2
• Transmission coefficients u lt 0.15 W/(m2K)
• Annual heat consumption lt 15 kWh/m2

10
Planned retrofit measures

• High level external thermal insulation (20 cm)
• Installation of high thermal performance windows
  (U0.8 W/m2K)
• Balanced ventilation system with heat recovery
• Solar collectors (appr. 140 m2)
• Controled heating system if needed
