Can Rivic complete similar multi-tenant commercial HVAC replacement for my Ward Hill Business Park or other Merrimack Valley multi-tenant commercial building?

Yes for multi-tenant commercial buildings with suitable configuration. Prerequisites: adequate per-tenant electric service (typical 200A per tenant for professional services, light industrial, or health/wellness businesses), rooftop area for distributed VRF outdoor condenser placement (typically one condenser per tenant suite), building owner authorization for shared HVAC infrastructure replacement, and tenant coordination for phased installation scheduling. Rivic handles building owner and tenant coordination throughout scope as part of installation project management. Typical installation range for multi-tenant commercial buildings: $28,000-$42,000+ per tenant suite depending on suite size, zones, equipment tier, and installation complexity. Building-wide scope typically $100,000-$250,000+ depending on tenant count and suite specifications.

Why distributed VRF instead of like-for-like shared RTU replacement?

R.E. selected distributed VRF for several reasons that don't apply to like-for-like RTU replacement: per-tenant zone control eliminating shared-RTU comfort challenges (multiple tenants reported comfort issues with the shared VAV zone control approach); per-suite metering capability for future billing flexibility (shared RTU requires operating expense allocation rather than direct metering); tenant satisfaction and retention improvement from independent HVAC control; building value improvement through modernized HVAC infrastructure. Distributed VRF costs approximately 40-60% more initial installation than comparable-capacity shared RTU replacement but the tenant-level advantages and building value improvements justified the additional investment for R.E.'s specific circumstances. Building owners with different priorities may reasonably prefer shared RTU replacement for lower initial cost.

How does multi-tenant coordination differ from single-tenant installation?

Multi-tenant coordination adds complexity across several dimensions: individual tenant meetings and communication protocols established for each tenant's operational scope; sequenced installation phasing across tenant suites (typically 3-4 days per suite with 1-day gaps between sequential tenants); customized off-hours scheduling within each phase based on individual tenant operating schedules; transitional heating/cooling coverage during each tenant's installation phase; common area coordination (rooftop condenser installation, existing RTU decommissioning) scheduled to minimize simultaneous impact across all tenants. Rivic's project management scope includes all multi-tenant coordination as part of building owner installation project scope. Typical installation timeline for 4-tenant building: 14-21 days including tenant coordination and phased installation.

Why 4 independent systems instead of shared multi-tenant VRF configuration?

Independent per-tenant systems selected for the same reasons articulated across Rivic's other multi-unit residential and commercial case studies: per-tenant control (each tenant manages their own thermostat and comfort setpoints independently); per-tenant metering (each tenant's electric usage tracked through per-suite electric infrastructure); per-tenant equipment sizing matched to specific use case (physical therapy practice's 5-zone configuration differs from accountancy practice's 4-zone configuration; sizing matched to each tenant's Manual J commercial load calculation); per-tenant warranty coverage (each tenant's Mitsubishi Diamond Contractor warranty applies to that tenant's equipment). Shared multi-tenant VRF configurations are technically feasible but create allocation complications that R.E. and the tenants preferred to avoid.

What's the typical cost range for Ward Hill Business Park or other Merrimack Valley multi-tenant commercial HVAC installations?

Typical range: $28,000-$42,000+ per tenant suite depending on suite size, zones, equipment tier, and installation complexity. Building-wide scope for multi-tenant buildings typically $100,000-$250,000+ depending on tenant count and suite specifications. This case study's $124,800 combined reflects 4 independent Mitsubishi CITY MULTI VRF systems averaging approximately $31,200 per suite. Building-wide Mass Save Commercial rebate typically $15,000-$35,000+ depending on qualifying scope; IRA 179D commercial building deduction varies based on installation efficiency and building scope. Kathleen Brennan handles Mass Save Commercial and IRA 179D coordination as part of installation project management.

Investment: $124,800 combined installation, $22,000 Mass Save Commercial rebate (larger scope commercial installation qualifying), $18,000 estimated IRA 179D commercial building deduction, net $84,800

Situation

R.E. is the building owner of an approximately 12,800 sq ft multi-tenant commercial building in Ward Hill Business Park, Haverhill. Ward Hill Business Park is one of Haverhill’s substantial commercial corridors hosting light industrial, professional services, and small commercial businesses along the Ward Hill Ave corridor. The commercial park configuration includes multiple multi-tenant buildings with typical 2,000-4,000 sq ft tenant suite sizes.

R.E.’s building configuration: 4 tenant suites (approximately 3,200 sq ft each), 200A per-tenant electric service, shared building water and sewer utilities, individual tenant HVAC control through shared building rooftop unit (RTU) system with per-suite thermostat zones. Tenant mix: (1) small professional services office (accountancy practice), (2) light manufacturing/distribution (specialty equipment supplier), (3) health/wellness business (physical therapy practice), (4) small office suite (real estate services).

Existing HVAC configuration: shared building rooftop unit (RTU) system installed approximately 20 years ago serving all 4 tenant suites through central ductwork with per-suite VAV zone control. Original RTU 480V 3-phase power, gas heating with electric cooling. Both the gas heating and electric cooling components of the RTU showed significant declining reliability and efficiency including 3 emergency service calls in the previous 18 months.

R.E. had been considering coordinated RTU replacement for approximately 24 months. The 20-year RTU age combined with recent reliability issues and R.E.’s interest in fossil-fuel elimination for tenant retention and building value considerations drove the replacement decision timing. R.E. considered like-for-like RTU replacement vs distributed VRF configuration and selected VRF for the tenant-level advantages.

R.E. requested Rivic assess complete replacement options with priorities: (1) fossil-fuel elimination through heat pump conversion for Mass Save Commercial rebate and IRA 179D deduction, (2) per-tenant zone control improvement (existing VAV zone control had comfort challenges reported by multiple tenants), (3) per-suite metering capability for future flexibility (existing RTU allocated operating cost across tenants through building operating expense pass-through; per-suite metering enables direct tenant billing if lease terms permit), (4) coordinate installation with all 4 tenants to minimize business disruption, (5) reasonable capital cost given building’s Ward Hill Business Park commercial context.

Diagnostic and Assessment

Andrew Samples conducted the initial diagnostic assessment during a scheduled after-hours evening visit. Ryan Sullivan handled distributed VRF equipment specification given his commercial multi-zone experience. Kathleen Brennan coordinated with R.E. and the 4 tenants throughout the assessment scope to establish scheduling and communication protocols.

Key findings: (1) 20-year RTU at end-of-life with declining reliability and efficiency — heating and cooling components both approaching replacement necessity, (2) existing central ductwork acceptable but sized for the shared RTU configuration; distributed VRF configuration requires different ductwork approach (per-tenant compact ductwork rather than centralized building ductwork), (3) rooftop area adequate for 4 separate outdoor condenser units (one per tenant suite) plus removal of existing shared RTU, (4) 200A per-tenant electric service adequate for per-tenant heat pump installation with capacity margin, (5) all 4 tenants receptive to installation scope given the operational reliability improvements and comfort improvements expected, (6) property configuration favors 4 separate independent VRF systems (one per tenant suite) rather than shared multi-tenant VRF configuration — per-tenant independent systems provide the per-tenant control and metering capabilities R.E. prioritized.

ACCA Manual J commercial load calculation per tenant suite determined cooling load at 88°F summer design of approximately 42,000 BTU/hr per suite (varying with tenant use case) and heating load at 4°F winter design of approximately 32,000 BTU/hr per suite.

Solution: 4 Independent Mitsubishi CITY MULTI VRF Systems — One Per Tenant Suite

Rivic recommended 4 independent Mitsubishi CITY MULTI VRF systems — one per tenant suite — with per-tenant configuration matched to each tenant’s specific use case:

Tenant Suite 1 (accountancy practice) — 4-zone configuration: reception/waiting, conference room, open workspace, private office. Total 48,000 BTU/hr outdoor.

Tenant Suite 2 (specialty equipment supplier) — 3-zone configuration: customer showroom/reception, office/administrative, warehouse/storage (partial conditioning). Total 42,000 BTU/hr outdoor.

Tenant Suite 3 (physical therapy practice) — 5-zone configuration: patient treatment area 1, patient treatment area 2, reception/waiting, office/consultation, staff break. Total 60,000 BTU/hr outdoor.

Tenant Suite 4 (real estate services) — 4-zone configuration: reception/lobby, conference room, agent workstations, private office. Total 48,000 BTU/hr outdoor.

All indoor cassettes concealed ceiling installation matched to each tenant’s suspended ceiling infrastructure. Per-tenant refrigerant line-set routing through per-suite mechanical spaces to rooftop condensers.

Existing shared RTU decommissioning: RTU removed with proper EPA Section 608 refrigerant recovery; gas piping capped; existing central ductwork removed to accommodate the new distributed configuration.

Multi-Tenant Coordination Protocol

Kathleen Brennan coordinated with R.E. and all 4 tenants throughout the installation scope. Coordination protocol:

Initial tenant meetings: individual meetings with each tenant to communicate installation scope, timeline, and specific operational impacts. Tenants agreed to phased installation approach.
Sequenced installation: each tenant’s installation scope completed sequentially over 14 days (approximately 3-4 days per suite with 1-day gaps between sequential tenants). Sequencing allowed each tenant to prepare their specific suite for their installation window.
Off-hours scheduling within phases: installation work within each tenant’s phase scheduled during evenings and weekends where possible to minimize business disruption; specific tenants with different operating schedules (physical therapy practice with limited evening hours; specialty equipment supplier with morning-heavy schedule) received customized scheduling.
Transitional heating/cooling coverage: during each tenant’s installation phase, temporary heating (space heaters for winter installations) or cooling (portable AC for summer installations) provided as needed for essential business operations.
Common area coordination: shared RTU decommissioning and rooftop condenser installation scheduled during weekend periods to minimize noise and access impact across all 4 tenants simultaneously.

Installation completed with minimal business disruption across all 4 tenants. R.E. reported strong tenant satisfaction throughout the scope, contributing to tenant lease renewal discussions that concluded successfully in the months following installation.

Per-Suite Metering and Future Billing Flexibility

Distributed VRF configuration enables per-suite electric metering for the HVAC scope, providing R.E. future flexibility for direct tenant billing rather than the current operating expense pass-through allocation approach. Key considerations:

Existing lease terms: current tenant leases include operating expense allocation covering shared HVAC operating cost; no immediate change to tenant billing methodology.
Future lease negotiation flexibility: as tenant leases come up for renewal, R.E. has the option to negotiate direct HVAC metering and billing arrangements with per-tenant electric usage tracking through the distributed VRF configuration — may be attractive to tenants with efficient HVAC usage patterns.
Tenant transparency: per-suite metering provides visibility to each tenant of their specific HVAC operating cost, which some tenants find valuable for operating cost planning even without direct billing arrangement.

Outcome

Installation completed over 14 days across 4 tenant suites with minimal business disruption. Post-installation operational verification: all 4 independent VRF systems operating reliably. All 4 tenants reported comfort improvement compared to previous shared RTU operation. R.E. reported building value improvement through the modernized HVAC infrastructure and per-tenant control capabilities.

Ongoing Operating Cost Change

Post-installation first-year utility monitoring across all 4 tenant suites: total electric operating cost approximately $8,400 combined across all suites. Previous year utility costs (shared RTU allocated across tenants): approximately $14,200 combined including gas heating and electric cooling. Combined annual operating cost reduction approximately $5,800/year across the building. Reduced operating cost benefits R.E. through reduced building operating expense pass-through, benefiting tenant occupancy economics.

Investment Summary

Total installation cost (all 4 suites combined): $124,800 (four independent Mitsubishi CITY MULTI VRF systems, installation labor across phased schedule, refrigerant charging, commissioning, tenant coordination, existing RTU decommissioning)
Mass Save Commercial rebate: $22,000 (larger scope commercial installation qualifying)
IRA 179D commercial building deduction: approximately $18,000 estimated tax benefit
Net investment: $84,800 after Mass Save Commercial rebate and IRA 179D estimated deduction
Annual operating cost reduction: approximately $5,800/year across building
Additional value: tenant retention and satisfaction improvement; per-tenant zone control eliminating shared-RTU comfort challenges; per-suite metering for future billing flexibility; 12-year Mitsubishi Diamond Contractor warranty per tenant system; building value improvement through modernized HVAC infrastructure
