tions on page 3-10.
5. Moisture Control (Section 1312.1.4)
LW Complies. A one -perm vapor retarder is installed on the warm side (in winter) of all exterior
floors, walls and ceilings, and a ground cover is installed in the crawl space for both new and
existing buildings where insulation is installed. The plans/specs show compliance with this
requirement on:
Exceptions ❑ Exception. All new or altered building envelope components do not comply with the vapor

3 All cores except bond beams must contain rigid insulation inserts approved for use in reinforced masonry walls.
° Batt insulation installed in metal or wood frame walls shall be insulated to the full depth of the cavity, up to 6 inches in depth.
5 Shading Coefficient (SC) is the center of glass value and can be calculated from the Solar Heat Gain Coefficient using the
following equation: SC = SHGC + 0.87
6 Opaque smoke vents are exempt from U- factor requirements.
7 This value was set to allow a double -glazed skylight with a 0.5 inch air space with one pane tinted.
8 A tinted outdoor pane satisfies this requirement. Glazing for merchandise display is exempt from shading coefficient
requirements.
8 Each wall type is limited to a percent glazing specified in column (g) of the 'Walls' portion of the form.
t This value was set to allow a double -glazed window with a 0.5 inch air space, low -e coating (e <_ 0.40). That window or any
window with the same or better energy characteristics will meet the standard.

2.6 BUILDING MANAGEMENT SOFTWARE
A. Anti- Recycle Timer Protection: A software program shall be provided to allow
each individual piece of HVAC equipment to be individually programmable with
"minimum on ", and "minimum off" timers to protect HVAC equipment from rapid
cycling due to system or operator error. Minimum on/off timer program shall have
priority over all application software functions except fire shutdown and smoke
evacuation modes. Anti cycle times shall be obtained from equipment manufacturer
and all values verified at startup.
B. Space temperature control shall be based on Proportional and Integral control with
separate temperatures as follows:
1. unoccupied heating
2: occupied heating
3. occupied cooling
4. unoccupied cooling
5. morning warm -up temperature
C. Time of Day Scheduling:- The scheduling program shall have a minimum of 32
named master schedules. Each master schedule shall have a minimum of eight day
schedules (individual day of week schedules plus holiday day schedule. To these
master schedules, a minimum of 24 system loads (HVAC equipment etc.) or
groups of loads can be assigned. The master schedule shall be individually editable
for each of the day of the week and the holiday day. On any day, a minimum of .
five time of day events may be edited including:
1. • HVAC equipment Optimum Start with morning cool down/warmup,
whereby unit start time is calculated based on space temperature and
historical recovery rate
2. HVAC equipment Optimum Stop/coastdown with fan operation
maintained, whereby stop time is calculated based on space temperature
and historical drift rate
3. HVAC unoccupied mode
4. HVAC night purge start
5. HVAC and demand limit mode
