Property: Approximately 8,400 sq ft small-to-mid commercial tenant space within Rockingham Park redevelopment area, Salem NH
Tenant: B.L. (business owner alias — commercial tenant with tenant improvement allowance from building owner)
Scope: Complete tenant improvement HVAC installation for professional services business (specialty legal/consulting practice) within new commercial building on the Rockingham Park redevelopment area; 6-zone Mitsubishi CITY MULTI VRF configuration matched to office use case; NH regulatory framework coordination
Timeline: Diagnostic and design 4 weeks (including landlord tenant improvement allowance coordination), installation 8 days coordinated with building general contractor’s tenant improvement schedule
Investment: $58,400 installed, $5,000 NH Saves Commercial rebate (NH commercial rebate framework smaller than Mass Save Commercial), $9,000 estimated IRA 179D commercial building deduction (federal parity), net $44,400 combined tenant + landlord contribution
B.L. leases approximately 8,400 sq ft commercial tenant space within the broader Rockingham Park redevelopment area, adjacent to the Tuscan Village development. The Rockingham Park redevelopment area includes the substantial commercial/mixed-use redevelopment of the former thoroughbred horse racing track site in Salem NH — a distinctive southern New Hampshire commercial destination combining Tuscan Village mixed-use with additional commercial development in the surrounding area.
B.L.’s business (specialty legal/consulting practice with approximately 22 attorneys and support staff) recently relocated to the Rockingham Park redevelopment area from a smaller downtown Salem office location. B.L.’s lease includes tenant improvement (TI) allowance from the building landlord ($30/sq ft TI allowance = $252,000 total TI budget for space buildout including HVAC, interior partition, lighting, and finishes).
Tenant space configuration: 8,400 sq ft on a single floor with contemporary open-plan configuration modified for legal/consulting professional services use, including reception/waiting area (approximately 800 sq ft), 4 conference rooms varying sizes (approximately 1,600 sq ft total), 8 private attorney offices (approximately 1,600 sq ft total), open-plan support staff workspace (approximately 2,400 sq ft), 2 file storage/library rooms (approximately 800 sq ft total), IT/mechanical/utility spaces (approximately 400 sq ft total), staff break room (approximately 400 sq ft).
Original HVAC scope from building shell construction: rough-in for HVAC installation matched to tenant configuration but no equipment installed — tenant improvement scope required tenant to specify and install HVAC equipment as part of TI allowance. This is common in commercial building shell development where HVAC scope is coordinated with tenant use case and specifications rather than pre-installed by landlord.
B.L. requested Rivic assess installation options with priorities: (1) zone-level control across the 6+ distinct use areas (reception, conference rooms, private offices, open workspace, library/storage, break room) matching varied occupancy and comfort requirements, (2) NH regulatory framework coordination (Salem NH regulatory scope applies as introduced in the Tuscan Village case study), (3) coordination with building general contractor’s tenant improvement construction schedule to avoid delays, (4) NH Saves Commercial rebate coordination for eligible rebate scope, (5) IRA 179D commercial building deduction coordination.
Salem NH commercial installations follow the same NH regulatory framework introduced in the Tuscan Village residential case study, applied to commercial scope:
Andrew Samples conducted the initial diagnostic assessment. Ryan Sullivan handled commercial VRF configuration specification. Kathleen Brennan coordinated with the building landlord, general contractor, and B.L. throughout the tenant improvement scope.
Key findings: (1) tenant space rough-in from building shell construction adequately supports commercial VRF installation, (2) 400A per-tenant electric service adequate for commercial VRF installation with capacity margin, (3) rooftop area available for outdoor condenser placement per building landlord approval, (4) tenant space configuration favors 6-zone VRF configuration matching the diverse use area requirements, (5) integration with building general contractor’s tenant improvement construction schedule feasible with coordinated milestone timing (HVAC installation typically after primary interior partition and prior to final finishes).
ACCA Manual J commercial load calculation determined tenant space cooling load at 88°F summer design of approximately 96,000 BTU/hr including internal gains from occupancy and office equipment across the varied use areas, heating load at 4°F winter design of approximately 72,000 BTU/hr.
Rivic recommended Mitsubishi CITY MULTI VRF 6-zone configuration matched to tenant space use areas: (1) reception/waiting area 18,000 BTU/hr concealed ceiling cassette (variable customer occupancy 4-12 waiting patrons throughout business day), (2) conference rooms zone 30,000 BTU/hr concealed ceiling cassettes distributed across the 4 conference rooms with individual thermostat zones (variable occupancy 2-16 attendees per conference room), (3) private attorney offices zone 24,000 BTU/hr distributed across the 8 offices with individual thermostat control (consistent single-occupant use), (4) open-plan support staff workspace 24,000 BTU/hr concealed cassettes (consistent 10-16 staff occupancy), (5) library/storage rooms 12,000 BTU/hr concealed cassettes (variable file access occupancy with minimum cooling for document preservation), (6) staff break room 9,000 BTU/hr wall-mount cassette (variable occupancy with cooking heat load from break room food preparation). Total outdoor unit capacity 120,000 BTU/hr matched to Manual J commercial loads.
Rooftop outdoor condenser placement: 2 outdoor units (60,000 BTU/hr each) coordinated for tenant space zone distribution. Refrigerant line-set routing through building rough-in chases.
Contemporary commercial finishes preserved: all indoor cassettes concealed ceiling installation in the suspended ceiling grid that will be installed by building general contractor as part of finishes phase.
Kathleen Brennan coordinated with building general contractor and building landlord throughout the tenant improvement scope:
Installation completed within B.L.’s TI construction schedule without construction delays or scheduling conflicts with other TI trades.
Kathleen Brennan coordinated NH Saves Commercial rebate application for the qualifying installation scope. NH Saves Commercial framework:
Installation completed over 8 days coordinated with B.L.’s TI construction schedule. Post-installation operational verification: 6-zone VRF configuration delivers zone-level control across all distinct use areas. B.L. reported strong satisfaction with the zone-level control and independent thermostat operation across the diverse office areas.
Post-installation first-year utility monitoring: total electric operating cost approximately $9,800 for combined heating and cooling across the 8,400 sq ft tenant space. This represents baseline operating cost for the new tenant space installation (no prior operating cost history in this specific space given the new construction shell tenant improvement scope). Comparable industry benchmarks for professional services office in Salem NH climate suggest this operating cost profile is efficient.
Rockingham Park redevelopment area and Salem NH commercial VRF service including commercial tenant improvement HVAC installation coordinated with building general contractor’s construction schedule, tenant improvement allowance coordination with building landlord, multi-zone commercial VRF configuration for professional services and other commercial use cases, NH regulatory framework coordination (NFPA 54 base with NH amendments, no state HVAC contractor licensing), NH Saves Commercial rebate coordination (smaller scope than Mass Save Commercial), IRA 179D commercial building deduction coordination (federal parity NH and MA), and 12-year Mitsubishi Diamond Contractor warranty administration all route through our 225 Broadway #306 office in downtown Methuen (8-20 minute drive to Salem NH from Broadway). This case study represents a specific installation completed for B.L.; individual tenant assessments determine equipment specification and installation scope.
