Renewable HVAC technologies (ductless heat pumps, ground source heat pumps, biomass) will be a major source of the growth in the Massachusetts HVAC market over the next 5 years. In this talk, Peter McPhee who is the Renewable Thermal Program Director for the Massachusetts Clean Energy Center, will discuss the details of the program. In this talk, Peter talks about the following items. 1. The goals of the program for MassCEC and private industry 2. How the program will maintain flexibility over 5 years 3. The applicable technologies 4. How much the rebate amount is for each technology

Clean Heating & Cooling:
Overview of MassCEC’s 5‐Year Commitment

2. 2
Motivation for Clean Heating & Cooling
Massachusetts GHG
Primary Heating Fuel Used
MA Background
 Heating: 30% of MA GHG emissions
 MA GHG reduction goals:
 25% by 2020
 80% by 2050
 Requires tens of thousands of new clean
heating systems per year – starting now
Clean Heating Strategy
 MassCEC supports clean heating: ASHPs,
central biomass, GSHPs, solar thermal
 August 2015: 5-year, $30 Million commitment
 Goal: support rapid growth of industry into self-
sustaining, mature market

What is Success?
Grow the market significantly, but also focus on:
1. Technology maturation: higher efficiencies, proven reliability,
more consumer options
2. High-quality installations: improved reliability and performance
 Maximizing positive customer experiences
 Build trust and credibility
3. Cost-competitiveness: reduction in costs (especially soft costs)
 Growing competitive with fossil fuels, even with limited incentives
 Competitive, despite fuel price volatility
How MassCEC is working toward these goals
1. Aggressive technology standards
2. Quality control: training reqs, project reviews, and inspections
3. Performance monitoring

4. Air-Source Heat Pumps
4
Qualifying Technologies:
• Single-head and multi-head mini-splits
• High efficiency (COP of 1.75) and full-capacity at
cold temps: 7 manufacturers participate
Installer Qualifications:
• Manufacturer training required
• 2016: will require installer participation agreement
Rebate:
• $750 per single-head mini-split (max of 3), or
• $750 per heating ton (max of 5 tons)
• Mass Save rebate may also be available
Most Common Applications:
• Retrofits (no distribution system required)
offsetting electric, oil, or propane
• High-efficiency or net-zero homes
• Also provides A/C

5. Central Biomass Heating
5
Qualifying Technologies:
• Highest efficiency and cleanest systems: 80%
efficient, PM emissions <0.08 lb/MMBTU
• Currently only pellet boilers qualify
• 11 qualifying manufacturers
• Thermal storage usually required
Installer Qualifications:
• Manufacturer training required
• Installer participation agreement required
Rebate:
• 45% of installed costs up to $12,000
Most Common Applications:
• Offsetting oil
• Retrofits with hydronic heating distribution
• New construction with hydronic distribution

6. Ground-Source Heat Pumps
6
Qualifying Technologies:
• Highest efficiency “EPA Tier 3” systems
• Minimum COP of 3.1, 3.6, or 4.1 depending on type
• Open or closed loop, vertical or horizontal loop
Installer Requirements:
• IGSHPA accreditation required
• Installer participation agreement required
Rebate:
• $1500 to $2500 per heating ton (5 ton max)
Most Common Applications:
• New construction
• Retrofits with sufficient ductwork
• Some radiant floor applications
• Proper systems are extremely efficient
• Additionally offers A/C, hot water

7. Solar Heating and Hot Water
7
Qualifying Technologies:
• SRCC-rated collectors and systems
Installer Evaluation:
• Design reviews and inspections for new installers
• Participation agreement likely required in future
Rebate:
• Up to 40% of residential project costs
• Up to 65% of project costs for non-profits,
municipalities
Most Common Applications:
• Offsetting oil, electric, or propane water heating
• New construction or retrofits
• Some heating applications using radiant floor or
hydronic distribution systems
• Typically a back-up system is required

Considerations through 2020
Will technology standards change over the years?
 Yes. As technologies mature, so will our standards.
How certain is MassCEC funding?
 Very certain, but never absolute. Additional funding possible.
Will rebate levels change?
 As volume increases and costs reduce, rebates will adjust.
 MassCEC also takes into account other incentives available.
What about the Alternative Portfolio Standard and Mass Save?
 Some overlapping goals and incentives. We’re working to coordinate
rebates.
Are there financing options available?
 Yes. The Mass Save HEAT loan offers 0% financing.
Will there be commercial incentives available?
 MassCEC will likely offer commercial programs late this year.
