BMSEngineeringLLC New Addition Assessment
1. lntroduction
BMsEngineering LLC has been retained to evaluate the new 1020 square foot addilion for peak
heating loads and the existing boiler system.
2. Existing Residential Building
4. Gonclusions and Reeommendations
r The existing boiler system has sufficient capacity for the new addition heating requirements
. The connector hall area will require a minimum 32Btu/sq.ft. heat output if using radiant floor
heat. The tubing spacing will need to be between 4-6 inches'
r Recommend instailing a 2kw electric unit heater in the garage area and maintaining space
temperature above 32degF.
. ln consideration of using split system heat pumps as an alternative, recommend installing
electric floor heat in the bathroom area.
Gonstruction
The existing residential is a single-story home, approximately- 1000sq.ft with slab on-grade and shed
roof. lt is asiumed the existing-home meets the minimum 2009 lEcc requirements for building
envelopes.
Heating System
The existing primary heating source is a natural gas fired boiler (Veissman Model: B2HA 19) with a
67,0008tu/[i input ino oz,d'ooBtu/hr output. With derate and losses, actual output is 55'000Btu/hr.
in" noit"r supplies neatini water to a radiant floor and indirect domestic water heater. The domestic
water is suppiemented byi solar hot water system. The estimated heat loss during peak design
conditions is 19,000 to 20,000 Btu/hr.
3. New Residential Addition
The new addition is a two story, 1020sq.fi. which includes a 300sq.ft. garage area. The calculated
heat loss for the new addition,-not including the garage area is 21,0008tu/hr at peak design
conditions. See attached ManualJ calcs.

Note; Since the system is multizsne, the Peak Fenestration Gain Procedure was used to determine glass sensible gains
at ihe room and zone levels, so the sums of the zone sensible gains and airflows for cooling shown above are not intended
to equal the totals at the system level. Room and zone sensible gains and cooling cFM values are for the hour in which
the glass sensible gain for'the zone is at its peak. Sensible gains at the system level are based on the 'Average Load

Area values shown include only those rooms for which radiant floor properties have been entered.
Sensible heat loss values on this report do not include losses associated with ductwork, ventilation, winter humidification or
hot water piping.
Tubing lengths include only the tubing that is part of the radiant floor panel itself and not the supply and return piping to
and fr:om tfie manifold. lubing lengths are caiculated from the Tubing Spacing input and an assumed installed coverage
area that is based on a 6-inch offset from each wall around the perimeter of a rectangular room.
The Floor Heat Output Btuh values shown are calculated with the assumption that the tubing is installed to fill the room at
the given spacing.
lf the Supplemental Heat Required is negative, the radiant floor output exceeds the sensible loss of the room by the
indicated amount, assuming that the tubing is installed to fill the room at the given spacing.
