The Limestone City’s Walls Don’t Behave Like Anything in a Load Table’s Defaults
Kingston’s most valuable housing stock is 200-year-old coursed limestone — walls two feet thick with no cavity, no insulation, and enormous thermal mass. Model them like a modern 2×6 wall and the numbers are fiction; guess conservatively and the equipment is oversized. Meanwhile the city’s other permit stream is the opposite problem: student-district conversions to multi-unit housing, where each unit needs its own documented heating and ventilation. Both live or die on a real room-by-room calculation and drawings that show the distribution — which is exactly what OBC 2024 has the City of Kingston reviewing for.
Default Assemblies on Limestone Walls
Software defaults have no entry for 600mm coursed limestone. A calculation that models it as “masonry, uninsulated generic” misses the mass effect and the real conductance — the load is wrong in both directions by room.
Wrong room by roomConversions Without Per-Unit Design
Kingston’s student-district conversions get reviewed unit by unit: each needs its own heat loss, independently controlled heating on the drawings, and an MVDS. One furnace feeding four units doesn’t pass.
Returned at intakeComplete BCIN Mechanical Package
Room-by-room CSA F280 at -22°C with real assemblies — limestone included — duct or hydronic distribution design, MVDS and Schedule 1, stamped for City of Kingston submission.
Accepted first submissionExactly What the City of Kingston Expects to See
Heritage retrofits in Sydenham Ward and Portsmouth, multi-unit conversions near Queen’s, additions across the townships, and new builds in Westbrook and Amherstview — one complete mechanical package.
Room-by-Room CSA F280 Heat Loss & Gain
Every room calculated separately at Kingston’s -22°C design temperature — walls, windows, ceiling, floor, infiltration.
Equipment Sizing Sheet
Right-sized furnace, heat pump, boiler, or AC matched to the calculated load — not a square-footage guess.
Duct or Hydronic Layout Drawings
Fully dimensioned supply and return layout with airflow for every room per HRAI standards.
MVDS & Ventilation Design
The Mechanical Ventilation Design Summary — mandatory on every Ontario new-home permit since January 1, 2025 — plus HRV/ERV selection.
Schedule 1 & BCIN Stamp on Every Page
Signed designer declaration and BCIN stamp throughout — exactly what the City of Kingston requires before issuing your permit.
Interior insulation retrofits on limestone change the moisture physics as well as the load — the calculation reflects the actual retrofit assembly, and the high-velocity distribution threads existing structure without gutting heritage fabric.
Serving Kingston, Amherstview, Odessa, Gananoque & the Townships
Kingston reviews residential mechanical documentation to the full OBC 2024 standard: CSA F280 heat loss, distribution design, MVDS and Schedule 1. Heritage properties add HVAC constraints (no exterior wall penetrations on protected elevations, limited chase space) that only a drawn design resolves before construction.
The conversion market near Queen’s runs on per-unit documentation — every unit its own zone, its own numbers, its own ventilation. We produce the complete stamped set from your floor plans in 48 hours, formatted for Kingston’s e-permit submission.
Only Need the Heat Loss Report?
The full HVAC design package is $695 flat. If your Kingston project only requires the certified CSA F280 heat loss calculation, that’s $395 — see the Kingston heat loss page. Same 48-hour delivery.

The questions Kingston homeowners and builders ask most — answered in plain language.
What’s the difference between this and the $395 heat loss report?
The $395 report is the certified CSA F280 calculation only. The $695 package adds the distribution design (ducted, high-velocity or hydronic), equipment selection, ventilation design with MVDS, and stamped mechanical drawings. Just need the report? →
Can you calculate a limestone heritage home accurately?
Yes — we model the actual assembly: stone thickness, retrofit insulation, real window specs. Heritage retrofits are one of our most common Kingston project types, and the distribution design works within heritage constraints instead of ignoring them.
What does a multi-unit conversion near Queen’s need?
Per-unit heat loss calculations, independently controlled heating for each unit shown on the drawings, ventilation with an MVDS per dwelling unit, and a signed Schedule 1 — all BCIN-stamped. We produce the full set from your conversion plans.
