2 Canmet. ENERGY is the federal government’s technical research and knowledge base in the development of new clean energy technologies, regulations, codes, standards, policies and programs. Provides scientific and technical expertise in the following areas: • • • Clean Fossil Fuels Renewables Energy Efficiency • Buildings and Communities • Industrial Processes • Transportation

6 Research Priorities Decision Support Tools § Cost Optimization (Affordability) Platform § Energy simulation tools § Stock analysis § Technology assessment Technology Innovations § Advanced Wall Systems § Integrated Mechanical Systems § Alternative heating, cooling and ventilation distribution strategies § Integration of renewables We evaluate a wide range of technologies… . . in our test and field facilities. . and provide tools that enable Canadian manufacturers and builders to use our research results to improve their products

9 These all fit in a 2 x 6” wall 2012 NBC Code MNECH Code 1993 R 2000 Program 1983 R 2000 Program Super Energy Efficient Housing Program Need: State of the art walls are not future-ready But tomorrow’s homes require more insulation

New materials promise high R-values But integration remains a challenge 10 Problems: • Thermal bridging • Construction Practice • Durability • Moisture & Mould Our solution: thin wall panels that integrate new materials to overcome these barriers.

11 We also need a strategy for existing homes • ~2/3 of the 2050 Canadian Housing Stock is already standing • NRCan targets a 60% energy intensity reduction of the stock by 2050. • Current energy retrofit best-practice achieves about 22% improvement on average. • We will need transformational approaches to reduce the heat loss of the housing stock that will be more affordable, faster and less intrusive. New Homes The 2050 Housing Stock: Already standing

Retrofit Opportunity 12

13 Uptake in Prefabrication § Number of factories doubled from 2001 to 2012, to 123 § Lots of prefab components § 25% of sector set to retire in the next decade § Most sources expect a labour shortage

14 Benefits go beyond utility bills After Before Images: Todd Smith Exterior Retrofits offer highest renovation cost recovery rates Remodelling Magazine, Cost vs. Value report 2013 73%

17 Cold Climate Air Source Heat Pumps Central A/C + furnace § CCASHP COP from 1. 5 to 2. 4 in heating § Nat. Gas has COP <1 Ducted cold climate air source heat pump

20 Summary § Cold climate air source heat pumps work at cold temperatures § CC-ASHP use half the energy within the home of a natural gas system § CC-ASHPs have paybacks less than 5 years vs. fuel oil or electric baseboard heating § CC-ASHP, with very low power draws, are well suited to low energy homes and utility peak demand reduction programs § Natural gas would need to double in price for CC-ASHPs to be cost competitive with gas (Ottawa prices) Key Resource • Jeremy Sager • Martin Thomas For more information: Jeremy Sager Jeremy.

24 Andy Asked me…. . § What are the current research projects being done by your team that will directly support NZ housing § § § What are conceptual studies/technology reviews that your team thinks might be helpful to the NZ industry. . . but you need partners and some one to step up and support from the private sector § § § Cost Optimization/Affordability Envelopes (new, existing) Low output space heating (HP, m. CHP) Distribution strategies (zoned) Integration of Renewables Cost Data Supply Chain – whats new/whats on the horizon Monitoring of existing NZ Homes Overhaul distribution system design/sizing What "unintended consequences" from advancing code requirements and NZ type housing has your team identified as critical concerns or issues § § Affordability – Stress Test? Behavioral elements in a Standard/Code
