It keeps the project fully electric, which preserves eligibility for available incentives and aligns with the direction Massachusetts energy code is heading, and it is a straightforward package to build. The air barrier sits on the sheathing, which concentrates envelope detailing at one layer, and the package is being filed as drawn.</p><img src="/projects/cs82/image1.png" alt="What Changes Between Paths" style="max-width:100%;height:auto;display:block;margin:1rem 0;" /><p><strong>Code Path</strong></p><img src="/projects/cs82/image2.png" alt="Code Path" style="max-width:100%;height:auto;display:block;margin:1rem 0;" /><p><strong>Permit / Certificate of Occupancy Requirements</strong></p><img src="/projects/cs82/image3.png" alt="Permit / Certificate of Occupancy Requirements" style="max-width:100%;height:auto;display:block;margin:1rem 0;" /><p><strong>High Rise Buildings (Specialized Opt-In)</strong></p><img src="/projects/cs82/image4.png" alt="High Rise Buildings (Specialized Opt-In)" style="max-width:100%;height:auto;display:block;margin:1rem 0;" /><p><strong>Code Path</strong></p><ul><li><strong>HERS:</strong> Boston Specialized Opt-In.

This requires pre-approval via an application to be submitted before construction starts. This rebate comes in the form of a check within 4 months of certification documentation being provided to MassSave, typically this is 4 months after construction is complete.</li><li><strong>DOER Alternative Energy Credits ($0 - $45,000) </strong>
1<a href="https://www.mass.gov/info-details/qualifying-air-source-heat-pump-in-the-aps"><strong>(Program Breakdown)</strong></a><strong>:</strong> This rebate is received for installing APS eligible air source heat pumps (click here for the list). There is an extensive process to get this incentive. It comes in the form of a check approximately 6-12 months after the heat pumps are installed and fully operational.<ul><li><strong>IMPORTANT:</strong> Although an estimate is provided, this incentive can vary widely typically between $300-1,500 per heat pump. It's based on expected kWh usage of the system as well as the market value of the alternative energy credits when sold.</li><li><strong>Risks:</strong> Massachusetts is rewriting this program right now. The House bill would stop the state from accepting new applications on January 1, 2028, the Senate version leaves heat pumps out of that cutoff, and the two are in conference. The application needs the equipment installed and operating, so a project that will not reach that point before the deadline should treat this as upside rather than a budgeted line.</li></ul></li></ul><p><strong>HVAC Design Loads</strong></p><p>Suffolk County, MA · heating 1.0°F/70.0°F · cooling 90.0°F/75.0°F · loads include a bad-install allowance (UA +8%, infiltration +25%, recovery held to 60%) · all values kBtuh</p><p><strong>Design heat loss · components</strong></p><table><tr><td><p>Unit type</p></td><td><p>Walls & rim joists</p></td><td><p>Roof / ceiling</p></td><td><p>Slab, floors & below grade</p></td><td><p>Windows & doors</p></td><td><p>Infiltration</p></td><td><p>Ventilation</p></td><td><p>Design heat loss</p></td><td><p>Design heat loss at selection</p></td></tr><tr><td><p>1-Bedroom</p></td><td><p>1.1</p></td><td><p>0.9</p></td><td><p>â</p></td><td><p>2.1</p></td><td><p>3.2</p></td><td><p>2.1</p></td><td><p>9.4 @ 1°F</p></td><td><p>9.4 @ 1°F</p></td></tr><tr><td><p>2-Bedroom</p></td><td><p>1.3</p></td><td><p>1.2</p></td><td><p>â</p></td><td><p>2.8</p></td><td><p>3.9</p></td><td><p>2.7</p></td><td><p>11.9 @ 1°F</p></td><td><p>11.9 @ 1°F</p></td></tr><tr><td><p>3-Bedroom</p></td><td><p>1.5</p></td><td><p>1.4</p></td><td><p>â</p></td><td><p>2.4</p></td><td><p>4.3</p></td><td><p>2.7</p></td><td><p>12.2 @ 1°F</p></td><td><p>12.2 @ 1°F</p></td></tr></table><p><strong>Design heat gain · components</strong></p><table><tr><td><p>Unit type</p></td><td><p>Solar through glazing</p></td><td><p>Envelope conduction</p></td><td><p>Internal gains</p></td><td><p>Infiltration & ventilation</p></td><td><p>Latent</p></td><td><p>Total heat gain</p></td><td><p>Sensible heat ratio</p></td></tr><tr><td><p>1-Bedroom</p></td><td><p>1.0</p></td><td><p>0.9</p></td><td><p>2.1</p></td><td><p>1.8</p></td><td><p>2.6</p></td><td><p>8.4</p></td><td><p>0.69</p></td></tr><tr><td><p>2-Bedroom</p></td><td><p>2.1</p></td><td><p>1.2</p></td><td><p>2.3</p></td><td><p>2.3</p></td><td><p>3.5</p></td><td><p>11.4</p></td><td><p>0.69</p></td></tr><tr><td><p>3-Bedroom</p></td><td><p>1.4</p></td><td><p>1.2</p></td><td><p>2.5</p></td><td><p>2.4</p></td><td><p>3.8</p></td><td><p>11.4</p></td><td><p>0.67</p></td></tr></table><p><strong>Selection</strong></p><table><tr><td><p>Unit type</p></td><td><p>Cooling Capacity</p></td><td><p>Minimum Heating Capacity</p></td></tr><tr><td><p>1-Bedroom</p></td><td><p>7.6 â 20.0 kBtuh</p></td><td><p>⥠9.4 kBtuh @ 1°F</p></td></tr><tr><td><p>2-Bedroom</p></td><td><p>10.3 â 20.0 kBtuh</p></td><td><p>⥠11.9 kBtuh @ 1°F</p></td></tr><tr><td><p>3-Bedroom</p></td><td><p>10.3 â 20.0 kBtuh</p></td><td><p>⥠12.2 kBtuh @ 1°F</p></td></tr></table><p><strong>ENERGY STAR Total UA</strong></p><table><tr><td><p>Item</p></td><td><p>Detail</p></td></tr><tr><td><p>Climate zone</p></td><td><p>IECC 5A (2021 IECC map)</p></td></tr><tr><td><p>Program</p></td><td><p>ENERGY STAR MFNC National v1.2 Rev. 05</p></td></tr><tr><td><p>Rule</p></td><td><p>Design Review Item 2.1 / Fn 11-12; Proposed UA ⤠Reference UA</p></td></tr><tr><td><p>Code reference</p></td><td><p>Exhibit 1 Table 1 (2021 IECC CZ); Design Review Item 2.1 / Fn 11-12</p></td></tr><tr><td><p>Version basis</p></td><td><p>explicit program key (v1.2)</p></td></tr><tr><td><p>Note</p></td><td><p>Code minimum for this permit is v1.1; v1.2 used for explicit program key (v1.2).

This requires pre-approval via an application to be submitted before construction starts. This rebate comes in the form of a check within 4 months of certification documentation being provided to MassSave, typically this is 4 months after construction is complete.</li><li><strong>DOER Alternative Energy Credits ($0 - $45,000) </strong>
1<a href="https://www.mass.gov/info-details/qualifying-air-source-heat-pump-in-the-aps"><strong>(Program Breakdown)</strong></a><strong>:</strong> This rebate is received for installing APS eligible air source heat pumps (click here for the list). There is an extensive process to get this incentive. It comes in the form of a check approximately 6-12 months after the heat pumps are installed and fully operational.<ul><li><strong>IMPORTANT:</strong> Although an estimate is provided, this incentive can vary widely typically between $300-1,500 per heat pump. It's based on expected kWh usage of the system as well as the market value of the alternative energy credits when sold.</li><li><strong>Risks:</strong> Massachusetts is rewriting this program right now. The House bill would stop the state from accepting new applications on January 1, 2028, the Senate version leaves heat pumps out of that cutoff, and the two are in conference. The application needs the equipment installed and operating, so a project that will not reach that point before the deadline should treat this as upside rather than a budgeted line.</li></ul></li></ul><p><strong>Path Comparison - Net Cost Summary</strong></p><table><tr><td><p>Path</p></td><td><p>Total Cost $/sf</p></td><td><p>Total Incentives $/sf</p></td><td><p>Net $/sf</p></td><td><p>OpEx Factor</p></td></tr><tr><td><p>Current</p></td><td><p>$59.50</p></td><td><p>$2.43</p></td><td><p>$58.11</p></td><td><p>1.02</p></td></tr></table><p><strong>Path Comparison - Envelope</strong></p><table><tr><td><p>Item</p></td><td><p>Path</p></td><td><p>Detailed Specifications</p></td><td><p>Cost $/sf</p></td><td><p>Incentive $/sf</p></td><td><p>Net $/sf</p></td><td><p>OpEx</p></td></tr><tr><td><p>Exterior Walls</p></td><td><p>Current</p></td><td><p>⥠R-21 cavity insulation (2x6 @ 16" o.c.) with ⥠R-9 continuous exterior insulation.</p></td><td><p>$5.85</p></td><td><p>$0.00</p></td><td><p>$5.85</p></td><td><p>0.95</p></td></tr><tr><td><p>Below Grade Walls</p></td><td><p>Current</p></td><td><p>N/A</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>1.00</p></td></tr><tr><td><p>Corridor Walls</p></td><td><p>Current</p></td><td><p>N/A</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>1.00</p></td></tr><tr><td><p>Slab</p></td><td><p>Current</p></td><td><p>N/A</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>1.00</p></td></tr><tr><td><p>Floor Over Unconditioned Space</p></td><td><p>Current</p></td><td><p>N/A</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>1.00</p></td></tr><tr><td><p>Floor Over Garage</p></td><td><p>Current</p></td><td><p>⥠R-30 continuous insulation.</p></td><td><p>$0.86</p></td><td><p>$0.00</p></td><td><p>$0.86</p></td><td><p>0.90</p></td></tr><tr><td><p>Floor Over Podium</p></td><td><p>Current</p></td><td><p>N/A</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>$0.00</p></td><td><p>1.00</p></td></tr><tr><td><p>Rim Joists</p></td><td><p>Current</p></td><td><p>⥠R-21 rim/band insulation at floor transitions.</p></td><td><p>$0.20</p></td><td><p>$0.00</p></td><td><p>$0.20</p></td><td><p>0.95</p></td></tr><tr><td><p>Roof</p></td><td><p>Current</p></td><td><p>Sealed attic: ⥠R-19 insulation + ⥠R-30 continuous insulation.</p></td><td><p>$1.14</p></td><td><p>$0.00</p></td><td><p>$1.14</p></td><td><p>1.10</p></td></tr><tr><td><p>Windows & Glass Doors</p></td><td><p>Current</p></td><td><p>High performance, U ⤠0.25 / SHGC ⤠0.25.</p></td><td><p>$7.06</p></td><td><p>$0.00</p></td><td><p>$7.06</p></td><td><p>1.00</p></td></tr><tr><td><p>Doors</p></td><td><p>Current</p></td><td><p>Opaque door, U ⤠0.20 (R-5.0).</p></td><td><p>$0.38</p></td><td><p>$0.00</p></td><td><p>$0.38</p></td><td><p>0.95</p></td></tr><tr><td><p>Air Sealing</p></td><td><p>Current</p></td><td><p>⤠0.27 CFM50 per sqft of enclosure (compartmentalization); tested.</p></td><td><p>$1.30</p></td><td><p>$0.00</p></td><td><p>$1.30</p></td><td><p>0.95</p></td></tr></table><p><strong>Path Comparison - Mechanical</strong></p><table><tr><td><p>Item</p></td><td><p>Path</p></td><td><p>Detailed Specifications</p></td><td><p>Cost $/sf</p></td><td><p>Incentive $/sf</p></td><td><p>Net $/sf</p></td><td><p>OpEx</p></td></tr><tr><td><p>HVAC</p></td><td><p>Current</p></td><td><p>Ductless multi-split cold-climate air-source heat pump, SEER2 ⥠17 / HSPF2 ⥠10<br>1BR: 20 kBtuh 2-zone<br>2BR: 20 kBtuh 3-zone<br>3BR: 20 kBtuh 4-zone<br>sized to the worst-case design load per bedroom count, see HVAC Design Loads</p></td><td><p>$16.73</p></td><td><p>$0.00</p></td><td><p>$16.73</p></td><td><p>
