Local Energy Efficiency Partnerships ‘LEEP 2.0’, field trial trends, and technology costing

April 24th, Spring Training Camp 2017 – Huntsville, Ontario

Presented by Patric Langevin, LEEP Facilitator and Technical Lead

Policy and Planning Branch, Innovation and Energy Technology Sector


LEEP Accelerates Home Builder Innovation

Enables builders to:

• reduce their time and risk in finding and trying innovations that can help them build higher performance homes better, faster and more affordably.

• use federal research results to inform their technology decision making.

• pool their buying power regionally to make it worthwhile for manufacturers to address the builder group’s issues. Builders in LEEP groups typically represent 50% of local production.

“LEEP assists with bringing innovation into the market in a well thought out and responsive way.”


The builder viewpoint: Change can lead to cost, schedule and call back problems… There are many options out there… which to consider & why?


LEEP 2.0 Delivery Model

Builder Planning Workshop: where technologies are

selected

Start

LEEP Technology Forums: enabling ‘apples to apples’

comparison

~ 3 months later

Builder Technology Trials: unlocking market change

& inform NRCan

Completed within ~ 16 months

New LEEP Tech Guides: following each market’s

field trial learnings

Ongoing – web search: NRCan LEEP


Responsive to regional builder needs Content and presenters change according to market interest.

LEEP BC Field Trial Trends


LEEP BC CSA F280-12 field trial home analysis

example

Design heating load

Using BCBC spec and ‘rule of thumb’

Using BCBC spec and CSA F280-12 analysis

With one upgrade option for: envelope, windows and air tightness

80,000 Btu

Note: Some builders were quoted systems that were oversized by a factor of 3 or more!


LEEP’s Costing Spreadsheet Allows builders to estimate the cost of innovative technologies in their homes


Allows user to: 1. Define base case home

geometry.

2. Define base case home specifications.

3. Define specific upgrade scenarios according to regional needs.

LEEP’s Costing Spreadsheet


LEEP’s Costing Spreadsheet

• Underlying database provides sq. ft. costs for materials and labour.

• Data based on Hanscomb Costing Study (2012), with updated costs based on data collected through LEEP processes

• All costing sheets pull from this tab.


LEEP’s Costing Spreadsheet Pulls the base case wall or mechanical system from

“Base Cases” tab.

Builder or EA can modify assemblies based on system components. Spreadsheet

calculates costs.

Spreadsheet provides initial cost impact of system.


4 Ontario Workshops This Fall/Winter

Builders will be able to make decisions based on an ‘apples to apples’ comparison of 4 competing HVAC systems for homes with low design heating loads of 25,000 btu or less.

• All 4 presenting manufacturers will consider the same two homes and provide:

– Best practice applications

– Full installed HVAC system costing

– Answers to industry questions

Builders will be the first to use a new Mechanical System Decision Guide for Low Load Homes Heated with Natural Gas


4 Ontario Workshops This Fall/Winter

• Try new guide to mechanicals for homes with low design heating loads (currently being created by LEEP team is working with industry to create a

• Consider leading HVAC options for high performance homes

– Best practice applications

– Full installed HVAC system costing

– Answers to questions asked by previous LEEP builder groups

Presentation to be made by 4 competing manufacturers

– 2 will present furnace based systems

– 2 will present combo based systems

Focused on HVAC system for homes with design heating loads of 25,000 btu or less.

LEEP Next Steps

• LEEP for new housing market – Planning a staged roll-out across Canada

– Energy Star and Net-Zero Energy performance tiers will be built into all LEEP technology presentations

• LEEP for retrofit – Developing a first ‘pre-pilot’ in SW Ontario this year (more after the

panel)
