6 6 What is BIPV? Integral component of the building skin component that serves a dual purpose: Converts solar energy into electricity Fulfills one or several building envelope functions Safety Thermal Insulation Daylighting Weather Protection

7 Influence of BIPV Systems on Buildings 7 BIPV must comply with both PV and building codes and standards

8 Examples of BIPV Systems 8 Sloped, roof-integrated, accessible from within the building Non-sloped (vertically) mounted, not accessible from within the building Externally integrated, not accessible from within the building Photo credit: NRcan Copenhagen International School Denmark TD Bank Mississauga, ON Enwave Theatre Toronto, ON Residential building Switzerland Darmstadt solar decathlon house Germany

9 Pathways to BIPV 9 Commercialization (TRL) Technology Readiness Level (TRL) 1 Conceptual articulation 2 Technology and application described 3 Laboratory studies & analysis Tools (TRL 1) Standards requirements Model development Design & sizing tool development 4 Limited capability prototype validation in laboratory (pre-alpha version) 5 Full capability prototype validation in laboratory (alpha version) 6 Prototype validation in relevant environment (pre-beta version) 7 Actual system validation in relevant environment (beta version) 8 Initial production and rollout 9 Full production mode Collector (TRL 2-3 System (TRL 4-6) Design & optimization Testing protocols Collector testing System validation Whole system testing

10 BIPV Current R&D 10 Addressing 3 key challenges of the BIPV industry: 1. Standards and codes Support the development of standards and codes for BIPV (BIPV must comply with both building envelope and PV products standards and codes) 2. Cost-benefit Demonstrate the added value and cost-benefit of BIPV systems 3. Integration Develop design guidelines on how to integrate BIPV in buildings (envelope and HVAC system)

11 International BIPV Standardization Activities ISO Laminated solar PV glass for use in buildings 11 PT Building Integrated Photovoltaic

12 IEA PVPS Task 15 ( ) Enabling Framework for the Acceleration of BIPV Subtasks A - Case Studies B - Business Models C - Regulatory Issues D - Environmental Issues E - Applied Research and Development for the Implementation of BIPV Link: Publications: BIPV research teams & BIPV R&D facilities, an international mapping Planned Publications ( ): Book of BIPV case studies 2 Canadian case studies (Jeanne and Peter Lougheed Arts Centre, Enwave Theater) International Definitions of BIPV Analysis of User Needs for BIPV Functions

13 BIPV Cost-Benefit 13 BIPV: Building Envelope + Electricity Production BIPVT with thermal energy recovery (BIPVT) Building Envelope + Electricity Production + Thermal Energy Production In-depth analysis of various BIPV and BIPVT concepts using: Case studies Modelling Laboratory experiments Field testing

14 Case Study Jeanne and Peter Lougheed Arts Centre, Camrose, AL BIPV replaces exterior cladding (4 facades) Installed capacity: 122 kw DC Generates approx. 20% of the building energy consumption Completed in August 2014 BIPV system uses standard PV modules 14 Photo credit: University of Alberta

15 Case Study Varennes Library, 15 BIPV used as a rainscreen Installed capacity: 110 kw DC Varennes, QC Designed to generate 100% of the building energy consumption BIPV system uses standard PV modules Monitoring system to be installed in July 2018 Section Cavity Thickness Photo credit: Maxime Gagné Installed Capacity (DC) B C A A) Naturally ventilated 30 cm 67 kw B) Mechanically ventilated 15 cm 25 kw C) Mechanically ventilated with heat recovery 15 cm 18 kw

16 16 BIPVT with Air-Source Heat Pump Field testing to determine the overall system efficiency and the impact of preheating part of the heat pump fresh air intake System consists of 11 (DC & AC) air-source heat pumps (ASHP) with total heating capacity of 258 kbtu

17 Integration Review of Existing 17 BIPV Tools Qualitative evaluation completed More than 30 PV simulation tools and plug-ins were assessed 8 software and 2 plug-ins with BIPV simulation capabilities were identified No single solution can cover all the performance aspects of a BIPV system

18 18 Conclusion BIPV = PV + Building Envelope BIPV = Electricity Generation + Hygro-thermal + (Daylight) + (Thermal energy) BIPV R&D at NRCan focuses on: Standards and codes development Cost-benefit improvement and dispelling the myths Integration methods (with the envelope and HVAC system) Next Steps: Conduct a comparative evaluation of the robustness and performance of BIPV design tools using the Varennes Library as a case study Develop BIPV design guidelines for architects and engineers
