SECTION A. PROJECT COST AND ENERGY CONSERVATION
| A.1. |
| Every effort has been made to design a facility that effectively serves the user, is efficient to maintain, and minimizes the cost of construction. |
A.2 The cost of energy has been considered in the design of this facility. Provisions have been made to monitor all energy consumed by the facility. Where appropriate, an Internal Rate of Return (IRR) has been provided to justify the inclusion of energy conservation equipment.
| A.3 |

SECTION 7. ROOFING
| 7.1. |
| GENERAL. Low-slope roofs (slope is less than 76.2 millimeters [3 inches] per 0.3 meter [1 foot]) have historically experienced poor performance due to a variety of factors. Some of the conditions that contribute to early failures are identified in this section. |

| Can facility be designed with a pitched roof? |
| 7.1.2. |
| Does low-slope roof design provide for a minimum slope of 6 millimeters (0.25 inch) per 0.3 meter to ensure positive drainage of the roof surface? |
| 7.1.3. |
| Roof-mounted equipment properly mounted and flashed? (Mounting of mechanical and electrical equipment on the roof should be avoided. Rooftop equipment creates difficult flashing details, obstructs drainage paths, increases repairman traffic, accelerates corrosion and equipment weathering, and negatively affects maintainability of both the roof and equipment.) |
| 7.1.4. |
| Drains located at low points, with consideration given to the deflected position of the structure under load? (Interior roof drains are preferred over perimeter drains on low-slope roofs in cold climates.) |
| 7.1.5. |
| Design provides for sloping the frame of the building? (This is preferred over other methods of tapering the roof to achieve a positive slope.) |
| 7.1.6. |
| Roof drains to cold eaves? (Low-slope roofs should not drain to cold eaves in cold climates, as ice dams can develop and result in ponding.) |
| 7.1.7. |
| Scuppers provided at the proper height as a secondary means for drainage if the primary drains are blocked? (Scuppers should be approximately 50 to 76 millimeters [2 to 3 inches] above the level of the primary drains.) |

| 7.1.18. |
| Design specifies a minimum 18-gauge metal gravel stop or fascia strips? |
| 7.1.19. |
| Flashed joints are located above the roof waterline, or, if that is impractical, flashings are kept out of low areas where ponding may occur? |
| 7.1.20. |
| Protected membrane roof (PMR) system design specified to enhance R&M (based on life-cycle costs)? |
| 7.1.21. |
| Single-ply elastomeric membrane use, if specified, has been approved by major command (MAJCOM)? |
| 7.1.22 |
| If there is no insulation for the metal roof, is insulation above drop ceiling considered? If insulation exist, does it need to be replaced? |
| 7.1.23 |
| The occupants of the facility will be affected during the roof work? |
| 7.2. |

| 7.2.1. |

| 7.2.2.1. |
| Designer has investigated the use of a SSMRS based on lifecycle costs? |
| 7.2.2.2. |
| Is the optimum material specified? (Specify the use of aluminum alloy rather than aluminum/zinc-coated steel, as the estimated service life is up to 75% greater with aluminum panels.) |
| 7.2.2.3. |
| Design slopes are correct? (The design must provide for a minimum slope of 6 millimeters per 0.3 meter under normal atmospheric conditions. Near salt water areas, the minimum slope required is 12 millimeters [0.5 inch] per 0.3 meter to enhance the life of the panel.) |
| 7.2.2.4. |
| Design provides for a minimum of 50 millimeters of vaporretarding faced insulation for noise and condensation control under the metal panel, regardless of the thermal insulation values desired? |
| 7.2.2.5. |
| Where roof traffic is expected for equipment maintenance, does design provide a pre-designed serviceway to keep foot traffic, tools, and equipment from damaging the roof surface? |
| 7.2.2.6. |
| Is it required that the SSMRS be manufactured by a provider who has been regularly engaged in the fabrication of SSMRSs for at least ten years? |
| 7.2.2.7. |
| Is it required that the contractor installing the SSMRS has a minimum experience of two years? |
| 7.2.3. |
| Steep roofing (materials include rolled asphalt, asphalt strip shingles, clay tile, concrete tile, slate tile, wood shingles, and wood shake roofing systems): |
| 7.2.3.1. |
| Are special installation techniques used, as detailed in the NRCA Roofing and Waterproofing Manual? |
