3.1.5 Insulation finish designated "EXPOSED" will mean "NOT CONCEALED" as defined herein.

3.1.6 Mitre insulation at pipe elbow and wrap joint with adhesive tape. Where pipe is not to be recovered, cover joints with glass fabric reinforcing cloth pasted on and extending each side of joint throat for a distance equal to one covering diameter.

3.1.7 Insulation having a vapour barrier jacket shall be continuous where it passes through walls or floors. Protect exposed pipe insulation at floor line with 18 ga galvanized steel jacket approximately 100 mm high, secured to floor slab.

3.1.8 Tightly pack annular space between sleeve and pipe covering with insulation and fireproof vapour barrier where insulated pipes pass through sleeved openings in walls or floors. Packing shall extend full length of sleeve, and be finished flush at each end with caulking compound, aluminum colour.

3.1.9 Smooth aluminum sheeting used for re-covering shall be not less than 18 ga. thick on piping, ducts or equipment, and not less than 0.4 mm thick on pipework.

3.1.12 Rigid insulation shall be applied with edges tightly butted. Secure insulation to flat sheet metal surface by means of welded pins or perforated base metal fasteners and speed washers. Locate on not more than 450 mm centres throughout the sheet metal surface with a minimum of two rows per duct side, and adhere with a fire resistant cement. Attach speed washers, when insulation has been placed on the metal spikes and cut off the excess spike flush with washer and re-cover washer with foil faced vapour barrier tape. Cover angles or standing seams on the outside of plenums, casings and ducts which extend beyond face of applied rigid insulation with 12 mm layer of flexible insulation. Extend this insulation 75 mm on each side of the angles and place tight around the projecting leg of the angle. Apply rigid insulation overlapping edge of flexible insulation on angle so that vertical part of insulated angle projects through work.

3.1.13 Flexible insulation shall be wrapped tightly on to the ductwork with all circumferential joints butted and longitudinal joints overlapped a minimum of 50 mm. Insulation shall be adhered to duct surface with mechanical fasteners at 300 mm on centre.

2.17.1 Each piece of equipment being duty cycled may have its own unique temperature sensor as input to the DDC Controller which may be programmed to override the duty cycle off time, based on the environmental conditions of the space being served by the equipment. Alternatively, a common analog sensor such as outdoor air may be used to automatically shorten the off cycle time of all duty cycled equipment, based upon the difference of outside temperature from design conditions.

2.17.2 The BMCS shall be provided with an optimal start program such that the building may be divided into zones for optimum start. Warm-up and cool-down shall occur in sequence with succeeding zones starting only after the preceding zone has completed its warm-up or cool-down.

2.17.4 The optimum start program shall control start-up of the HVAC cooling and heating equipment to achieve the target occupancy space temperature at the precise time of building occupancy.

2.17.5 A built-in "learning" technique shall cause the BAS to automatically adjust itself to the most effective time to start equipment based on historical data.

2.17.6 The BAS shall be provided with an operator interactive time of day (TOD) program. TOD programming and modifying shall be accomplished in a calendar-like format that prompts the user in English language to specify month, year, day, time and associated point commands

2.17.8 TOD shall incorporate a holiday and special day schedule capability which will automatically bring up a pre-defined holiday or special day schedule of operation. Holidays or special days can be scheduled up to one year in advance.

2.17.9 In addition to the time dependent two state control, TOD also provides time dependent set point control. This control provides the capability to output assignable, proportional set point values in accordance with the time of day and day of week. This program shall be used to accomplish night setback, morning warm-up and normal daily operating set points of all control system loops, controlled by the BAS. As with the two state control, time dependent set point control shall be subject to the holiday schedule. The set points desired shall be user definable at any operator terminal.

2.17.10 The operator shall be capable of reading and/or altering all sorted data pertaining to time of day, day of week, on/off times, set point values, and holiday designation
