4 EmergingBIPV mainstream market? Market Social housing corporations Construction companies Energy performance (EPC, EPBD) Real estate value Products Low costs(savingon roof tiles) Good aesthetics Added functionality: Insulation & Heat 4 4

5 Social Housing Corporations Owner of many older and poorly insulated buildings: Terraced houses & Apartments Performance contract with local government on CO 2 emissions Mission to reduce housing costs for low income tenants Aestheticsseenas important for general neighbourhood status 5 5

10 Trends in BIPV for social housing corporations PV + insulation Thinfilm PV Heat recovery 10 10

11 Trend: Insulation + PV Insulation element or prefab roof Standard PV panel Innovative prefab mounting methods 000 Prefab mounting PV on insulation element Crane installation of integrated element 11 11

12 Why roof insulation + PV? Four energy label steps Calculation after NEN7120 Terracedhouse <1974 Energy label E RenovationwithRc = 4 m 2 K/W insulation& 4 kwppv Energy label A 12

13 Whyroof insulation& PV? 1500 euro/a energy savings Annual savings (eur/a) Savings from Insulation Savings from PV Roof insulation reduces heating demand in winter. PV reduceselectricitydemand. Combinedcostsavingsof 1500 euro/a. Year 13

14 Whyroof insulation& PV? Efficient mounting X X X X X 1. Insulation 2. Tiles 3. PV Conventional renovation Roof workers need to access the roof three times: 1. Insulation 2. Roof Tiles 3. PV Insulation Integrated PV Single time roof access! 14

15 Trend: Thinfilm PV Trend towards experimenting with thin film PV panels. Two key arguments: Lowercostper m 2 Better aesthetics 15

16 Low costper m 2 Costper m 2? csi160 Wp/m 2 x 0.50 /Wp= 80 /m 2 TF 100 Wp/m 2 x 0.40 /Wp= 40 /m 2 Avoided costs? Roof tiles40 /m 2 Exchange roof tilefortf without added costs! Betterbusiness case for10% TF than16% c-si System Panel Substract40 /m 2 avoided costs 16 16

17 Aesthetics No shiny tabs = Good aesthetics Good roof filling = Good aesthetics Houses : Typicalroof 4.80m x 6.40m c-si panel 1.05 x 1.65 gives63% roof filling TF panel 1.20 x 0.60 gives94% roof filling Small panel = Good aesthetics Roof tiles0.40m high TF panels 0.60m high csi panels m high 17 17

18 Trend: Heat recovery Heat is 2/3 of energy demand BIPV panels get hot Extraction via ventilation air (air-to-water heat pump or heat exchanger). Extractionvia water tubes (PVT) Real challenge is integral system design Heat Electricity 18 18

19 Conclusions Mainstream BIPV market emerging in Netherlands? Key segments: Social housing corporations Construction companies Typical project size houses Focus on BIPV withlow costs& goodaesthetics Future developments: Trend forpv + insulation Trend for experimenting with thin film PV Trend for heat recovery 19
