  1. CHBA Canadian Renovators’ Council October 27th, 2012Deep Energy Retrofit Plan Overview: 2012-2016Mark Carver,Project Officer, Housing Teammark.carver@nrcan.gc.ca 613-947-3155

  2. Objectives • To reduce the cost, time and uncertainty associated with deep-energy retrofits that achieve energy savings of 60% or more • To define innovative, cost-optimal strategies for integrating emerging technologies into existing homes

  3. AFTER BEFORE ‘Bread and butter’ retrofits Kitchen & Bathroom retrofits • Aesthetics are a large market driver • Trades coordination is routine • Project timelines can be relatively short and predictable Whole-home energy retrofit • Could it become another ‘bread and butter’ retrofit category? • What barriers would need to be overcome?

  4. Deep Energy Retrofit Opportunity • Canadians spend $26B on utility bills a year • By developing deep energy retrofit strategies to reduce energy use by 60% we could shift up to $16B annually from utilities to renovation sector • Average single-family homeowners spend $3500 / year on energy bills • 60% energy improvement = $2100/yr savings

  5. Whole-home energy retrofits • Improve aesthetics & .. • Significantly reduce energy costs • Increase resale value • Improve comfort • Reduce carbon footprint

Research Plan • MECHANICAL AND ELECTRICAL • COMBO SPACE AND WATER HEATINGCOMBINED HEAT AND POWER • HEAT/ENERGY RECOVERY VENTILATORS 14 LOW VOLTAGE DC LIGHTING • INTEGRATED MECHANICAL SYSTEMS (IMS) • PLUG-IN ELECTRIC VEHICLE READY GARAGE • ZONED FORCED AIR • ENVELOPE & CONSTRUCTION • ADVANCED FRAMING • TRIPLE GLAZED WINDOWSCOOL ROOF SYSTEMS • INSULATED CONCRETE FORMS [ICF]VACUUM INSULATION PANELSUNDERSLAB INSULATION • RENEWABLE ENERGY PASSIVE SOLAR DESIGN • PHOTOVOLTAIC [PV] MODULES • SOLAR HOT WATER SYSTEMS • SOLAR LIGHT TUBES • SOLAR READYURBAN WIND TURBINES • Engage industry • Assess technologies and retrofit approaches • Select 3 case study archetypes • Optimize costs • Package results and define pathways

  7. 1. Engage Industry • Select archetypes • Provide / validate cost data • Identify technologies and retrofit approaches • Identify barriers • Review specification and solutions

  8. 1. Engage Industry More impact More effort Less effort Less impact

  9. 2. Assess Technologies • 4-6 page documents describing: • Individual technologies or retrofit measures • How to install or integrate into existing homes • Market benefits • Cost/benefit analysis • Maintenance considerations • Code considerations

  10. Technology Assessments • Industry partners will help identify emerging technologies and retrofit approaches for assessment, i.e. • zoned forced-air • vacuum insulation panels (VIPs) • Cold-climate air source heat pumps • LED lighting

  11. Insulation & Sealing Windows MechanicalEquip. Renewable Energy Deep energy retrofit requires a a whole-house approach

  12. Simple Problems Quickly Become Complex

  13. 3. Simulation and cost optimization • We will use sophisticated optimization software to consider thousands of combinations of approaches Cost-optimal, whole-house renovation strategies

  15. Retrofit Pathways

  16. Prefabricated façades for retrofit • Upgrade Curb Appeal while… • air sealing • insulating • eliminating thermal bridging ..all within days

  17. Precise dimensioning via 3D Scanning technology • Cost (80% decrease in last 5 years) • Equipment: $50k • Service: ~$800-1000 / house • Point clouds can be imported: • Autodesk (AutoCAD, Revit, Inventor) • ArchiCAD • CATIA Video

  20. Thanks • Are you interested in Deep Energy Retrofit? • Are you interested in partnering to find faster, more affordable approaches? • If so, please get in touch Mark Carver Project Officer, Housing Team mark.carver@nrcan.gc.ca 613-947-3155

  21. Deep Energy Retrofit Need • Canadians spend $26B on utility bills a year • By developing deep energy retrofit strategies to reduce energy use by 60% we could shift up to $16B annually from utilities to renovation sector • Average homeowners spend $2100 / year on energy bills • 60% energy improvement = $1200/yr savings

  23. Initial Perceptions Complicated to install and costly ($5000 to $7000 range) Requires electrician Applicable in luxurious custom homes only Energy benefits a question mark Process Sufficient info in two staged selection process to enable builders to select it in – barely! Enabled builders to define what they 1) wanted presentations to focus on, & 2) who they wanted to present New area – experts needed to think through and develop new presentations to respond Perceptions Changed… Current issue: Common customer issue with heating and cooling in tall narrow homes Legitimacy: A few Ontario builders are applying in modestly priced homes with good results Complexity: Options are available that minimize installation issues Access & Liability: Options available that maintain access to dampers, and that leave liability with manufacturer Generic duct design approach: new generic duct design approach could be used with any centrally ducted system. Costed using a builders sample home at $100 more than traditional. Field Trials Results: Statistically valid energy analysis on zoned and unzoned systems. Results included 25% peak shaving & shifting during summer peaks on electrical grid, more with utility thermostat control Customer Feedback: Field trial results showed that 95% of homeowners surveyed felt that system was providing desired benefits and would recommend it to a friend. Costing: Manufacturers and suppliers saw opportunity to move from boutique sales to volume and dropped price significantly below that provided to builders currently using these products. Forced Air ZoningFinding opportunities that would otherwise be missed..

  24. Overview Objectives: • innovative, cost-optimal strategies for integrating emerging technologies into existing homes • to reduce the cost, time and uncertainty associated with deep-energy retrofits that achieve energy savings of 60% or more We will develop solutions to achieve these savings by: • partnering with the industry to ensure alignment • identifying emerging, transformative technologies; • evaluating their performance through technical assessments, modeling, and cost-benefit analysis; • using optimization software to find cost-optimal combinations of approaches; • developing strategies for incorporating such technologies into existing homes. Three researchers will carry out a variety of sub-projects to achieve these outcomes over the next four years.

  25. Why should energy retrofits matter for renovators? 2 important reasons: • Your client’s energy bills, their resale value and their home’s energy rating (ERS) • An energy retrofit represents an additional, simultaneous service that you can offer to compliment other renovations

  26. Energy costs • Canadian homeowners spend $3,314 a year in energy costs on average • Owners of typical new homes can expect to spend about $2,140 annually. Avg annual energy cost $5000 $4000 $3000 $2000
