5.2 Mechanical Systems
5.2.1 Heating and Ventilation System –Daycare Building
Space heating and ventilation to the daycare building is provided by one (1) “Rheem” gas
fired forced air furnace unit located in the storage room. The conditioned air is supplied to
corridors and rooms through a discharge grille located throughout the building. The unit is
original to the building (1993). The unit has maximum input capacity of 100,000 BTU/hr.
The supply air temperature is controlled by a thermostat located in the daycare area of
the building.

Figure 3: Supply Air Temperature Controller
The storage room houses a forced air furnace and DHW storage heater as shown in Figure
4. During site audit, it was found that the same room is used to store different items along
with the heating equipment.

5.2.1 Exhaust Systems
Air is exhausted from the two (2) washrooms by two (2) dedicated ceiling mounted
exhaust fans. The air is exhausted directly to the atmosphere through discharge cowls on
the roof. These exhaust fans are controlled manually by a switch.

5.2.2 Domestic Hot Water Systems
Domestic Hot Water (DHW) to the building’s plumbing fixtures is provided by one (1)
“RHEEM RUUD” domestic hot water heater (model# RF82-156C) located in the storage
room. The unit has input capacity of 156,000 BTU/hr and storage capacity of 82 gal. The
unit was installed in 1993 and is deemed to be at the end of its rated economical life as
determined by ASHRAE (American Society of Heating, Refrigerating and Air-
Conditioning Engineers).

5.2.3 Laundry Facility
The daycare building has one (1) laundry room. There is one (1) coin-operated front-
loading “MAYTAG” electric washing machine, and one (1) “MAYTAG” front-loading electric
dryer.

5.2.1 Typical Residential Suite System Description
Space heating and ventilation to each residential suite is provided by an in-suite forced air
furnace as shown in Figure 9. These forced air furnaces are manually controlled using
adjustable thermostats. Domestic hot water (DHW) is provided by dedicated DHW storage
tank water heater as shown in Figure 10. Each apartment has its own dedicated exhaust
serving the kitchen. The fractional HP fan motors are controlled by manual switch and
operate based on occupant usage. Each apartment is equipped with a refrigerator.

5.3 Heating and Ventilation Control System and Strategy
5.3.1 Control System
The facility does not have a central DDC controls system. The heating and ventilation units
are controlled via standalone thermostats. The forced air furnaces in the residential suites
are controlled by an adjustable thermostat as shown in Figure 11. The exhaust fans in
washrooms and kitchen are manually controlled by switches.
Figure 11: Thermostat for Forced Air Furnace
5.3.2 Maintenance and Operating Issues
The forced air furnaces and DHW storage heaters in the facility are at the end-of-
economic life and are requiring an increasing amount of repair.
The building envelope is deemed to be in average condition. Some envelope deficiencies
were observed including high rates of outdoor air infiltration through poorly sealed
entrances and exits. Doors and windows that are poorly sealed require additional heating
to maintain the building at desired temperature. Envelope upgrades could improve the
building’s overall R-Value.

5.3.3 Heating and Ventilation Equipment Tables
A complete inventory of heating equipment is provided in Appendix A.
5.3.4 Asset Management
Kinsmen Ravine Estates was built in 1993. It is typical with existing building that retrofits,
and upgrades take place throughout its lifespan and as such the record documentation
should be updated to ensure that efficient operation and maintenance can occur. It has
been well documented and proven on numerous facilities throughout Canada that
substantial energy and maintenance savings occur on facilities that actively participate in
an ongoing active asset management plan with paybacks ranging from 2-6 years.
It is highly recommended that a new active asset management strategy is implemented in
conjunction with the existing facilities team. A budget cost for an active asset
management strategy, including equipment asset renumbering/verification and new all-
inclusive operation and maintenance manuals is approximately $3,000.

5.4 Electrical & Lighting Systems
5.4.1 Description of Electrical Systems
Electrical power to the facility is distributed at 120/208V and is used for the facility’s
internal and external lighting, plug loads and mechanical equipment.
5.4.2 Lighting Description
The lighting in the daycare building at Kinsmen Ravine Estates is a mixture of T12 linear
fluorescent fixtures, screw-in incandescent lamps, LED exit signs and LED luminaires in
corridor as shown in Figure 14.

The site audit did not reveal any outstanding maintenance issues with the electrical
systems.
5.4.4 Non-mechanical Loads
The primary non-mechanical loads are related to the lighting, communication equipment
and plug loads.
• Total installed lighting power capacity: 5.0 kW
• Estimated annual lighting electricity consumption: 18,948 kWh
5.4.5 Lighting Levels
The lighting levels throughout the facility were within the recommended range in most
areas. In daycare classroom, lighting levels were lower than recommended levels as shown
in below table.

5.4.6 Lighting Control System and Strategy
The facility has no automated lighting control system. General lighting circuits are
controlled manually via wall switches. Exterior lighting is controlled via timer.
5.4.7 Plug Loads and Auxiliary Equipment
Plug loads include computers, copiers and scanners in the office, in-suite plug loads, and
laundry equipment.
Energy Accounting System
6 ENERGY ACCOUNTING SYSTEM
6.1 Description of Energy Accounting Methodology
Assessing energy use and evaluating efficiency is undertaken by benchmarking the facility’s annual
energy intensity (equivalent-kWh/m2/yr). This measure of building energy use must then be
referenced against buildings of similar vintage, climatic region, use, and type.
In order to best prioritize and discuss energy conservation opportunities at the facility, an
estimated end-use breakdown has been developed. This breakdown represents the probable
energy consumption by end-use based upon historical annual utility records, detailed data on
equipment and systems installed, and an understanding of facility operation strategies.
6.2 Historic Utility Records and Energy Intensity
The utility records and annual consumption profile for daycare building and underground parking
are summarized in the following table from June 2016 to May 2018. The utility records indicate a
relatively consistent consumption of energy over the last two (2) years.
The Newton Kinsmen Society pays for all utilities in daycare building and underground parkade.
The daycare building is served by three (3) BC Hydro electricity meters and one (1) FortisBC
natural gas meter.
Tenants pay for their own electricity and natural gas consumption. This study focuses on daycare
building and underground parking only.

ECM 01: Replace Existing Forced Air Furnace Unit with High Efficiency Air Source Heat
Pump Unit
The existing “Rheem” gas fired forced air furnace provides heated air to the building. The unit is
original to the building (circa 1993) and it is at the end of its rated economical lifespan and failures
due to age will increase in the future. Greenhouse gas emissions reductions (tonnes e-CO2/yr)
and energy savings would be observed if the existing unit is replaced with an air source heat
pump.
Total ECM 01 cost: $9,000
ECM 02: Replace Existing Forced Air Furnace with High Efficiency Condensing Air Furnace
Unit
The existing “Rheem” gas fired forced air furnace provides heated air to the building. The unit is
original to the building (circa 1993) and it is at the end of its rated economical lifespan and failures
due to age will increase in the future.
