1 TENANT STOREFRONT GLAZING PACKAGE CENTURY CITY

2 TENANT STOREFRONT GLAZING DESIGN PACKAGE Westfield Century City Los Angeles, California Westfield s Design Criteria for the Century City Mall Redevelopment calls for 14-0 tall glass which presents a number of design challenges from both a fabrication, structural, and Title 24 Energy compliance standpoint. This Glazing Design Package helps to provide the Tenant s Designer with the base guideline in which to provide their Engineer s in developing a final glazing solution that complies with the Westfield Design Criteria as well as the 2016 California Building and Title 24 Energy Conservation Codes. There are three (3) Storefront Design Options noted herein. Option 1 is comprised of two (2) stacked panels secured at their juncture via stainless steel spider-type fittings. The connected panels are then attached top and bottom to the base building. Utilizing SunGuard SNX 62/27 glass, said Option will meet the California Title 24 Prescriptive Method of energy compliance. Option 2 is comprised of a single panel unit attached top and bottom and butt-joined at the edges. The SunGuard SNX 62/27 glass is not available in 14-0 lengths and therefore must be fabricated with an SN68 or similar material which will NOT meet the California Title 24 Prescriptive method of energy compliance and must be calculated on a Performance Basis or Method. The Performance Method of compliance involves a cumulative calculation taking into consideration glass and glazing performance, electrical loads, heating and cooling loads, building shell insulation, etc. Depending on a myriad of factors, this method may impact desired light levels within the store and/or cooling capacity of the store s HVAC in an effort to comply with the Title 24 Standards. Option 3 is a variation of Option 2 in that a structural glass fin is used to provide additional wind load resistance to the glass panel by providing vertical resistance quarter-span. This Option, like Option 2, will NOT meet the California Title 24 Prescriptive method of energy compliance and must be calculated on a Performance Basis or Method. Glass Performance Spec Sheets and General Structural Details have been provided as a guideline for the Tenant s Designers and Engineers. Just as each Tenant s façade will be unique to their brand, so will their storefront glazing solution. Static, lateral, and wind loads must be taken into consideration as well as varying base building conditions, soffit framing, etc.. It is a fairly complex component of the larger whole that should be delved into early on in order to adequately design and engineer a comprehensive store front system. Engineered shop drawings will be required by both Landlord and the Building Department.

6 PERFORMANCE CALCULATOR a* b* Color Information: Outdoor Reflected Color Important Notes The performance values shown above represent NOMINAL VALUES for the center of glass with no spacer system or framing. Slight variations may occur due to manufacturing tolerances, point of manufacture, and type of instrumentation used to measure the optical properties. For configurations that include non-specular (diffuse) components, performance results cannot be verified and should only be used as a general indication of performance. For configurations which include ceramic frit coating, the actual values may vary significantly based upon the thickness and composition of the frit. For configurations with coatings laminated facing the PVB, there may be a noticeable color change. Guardian recommends a full size mock-up be approved. Calculations and terms in this report are based on NFRC Please note that the THERMAL STRESS GUIDELINE is only a rough reference to the thermal safety of a glazing. Other factors such as the size of glass areas, shapes and patterns, glass thickness, glass damaged during shipping, handling or installation, orientation of the building, exterior shading, overhangs/fins that reduce wind speed, and areas with high daily temperature fluctuations can all increase the probability of thermal breakage. The results shown are not for any specific glazing installation and do not constitute a warranty against glass breakage. Explanation of Terms % Transmittance Visible or Light Transmittance (τ v %) is the percentage of visible light at normal incidence (90 to surface) that PAGE 5

7 PERFORMANCE CALCULATOR is transmitted by the glass. % Ultraviolet (UV) Transmittance (τ uv %) is the percentage of ultraviolet light at normal incidence directly transmitted by the glass. Ultraviolet Light is defined as radiant energy from the sun having a wavelength range of 300 nm to 380 nm. % Solar Energy Direct Transmittance (τ e %) is the percentage of solar energy at normal incidence directly transmitted by the glass. Solar Energy is the radiant energy from the sun having a wavelength range of 300 nm to 2500 nm. % Reflectance Visible Outdoors or Light Reflectance Out (ρ v % out) is the percentage of visible light at normal incidence directly reflected by the glass back outdoors. % Reflectance Visible Indoors or Light Reflectance In (ρ v % in) is the percentage of visible light at normal incidence directly reflected by the glass back indoors. % Solar Energy Reflected Outdoors or Solar Direct Reflectance Out (ρ e % out) is the percentage of solar energy at normal incidence directly reflected by the glass back outdoors. % Solar Energy Reflected Indoors or Solar Direct Reflectance In (ρ e % in) is the percentage of solar energy at normal incidence directly reflected by the glass back indoors. Absorptance (α e %) (Solar, Visible or UV) is defined as a process in which a range of radiation is retained by a substance and converted into heat energy. The creation of heat energy also causes the substance to emit its own radiation. U-Factor or U-Value (U G ) is the air-to-air thermal conductance of 39" high glazing and associated air films. US Standard units are Btu/hr.ft².F. and SI / Metric units are W/m²K. Winter night values are 12.3 mph wind at -0.4 F outdoors and 69.8 F still indoor air. Summer values are 0 sun, 6.15 mph wind at 89.6 F outdoors and 75.2 F still indoor air. Relative Heat Gain (RHG) is the total net heat gain to the indoors due to both the air-to-air thermal conductance and the solar heat gain. Imperial units are Btu/hr.ft². RHG = [(Summer U-Value)(89.6 F F) + (Shading Coefficient)(200 Btu/hr-ft²)]. Metric units are W/m². RHG = [(Summer U-Value)(32 C - 24 C) + (Shading Coef.)(631 W/m²)] Shading Coefficient (SC) is the fraction of solar heat, direct (300 to 2500 nm) plus indirect (5 to 40 µm), transferred indoors through the glass. For reference, 1/8" (3.1 mm) clear glass has a value of 1.00 (SC is an older term being replaced by the SHGC). Solar Heat Gain Coefficient (SHGC) is the fraction of solar energy incident on the glazing that is transferred indoors both directly and indirectly through the glazing. The direct gain portion equals the direct solar transmittance, while the indirect is the fraction of the solar energy absorbed to the energy reradiated and convected indoors. No heat gain from warmer outdoor air is included. SHGC = (Direct Solar Trans) + {[(Indirect Solar Heat Gain) - (Summer U-Value)(89.6 F F)] / ( Btu/hr-ft²)} Light-to-Solar Gain (LSG) is the ratio of visible light gain to solar gain. LSG = (Visible Transmittance) / (SHGC) Color Rendering Index in transmission, D65 (R a ) is the change in color of an object as a result of the light being transmitted by the glass. Weighted Sound Reduction Index (Rw) is a single-number quantity which characterizes the airborne sound insulation of a material or building element over a range of frequencies. Sound Transmission Class (STC) is a single-number quantity which characterizes the airborne sound insulation of a material or building element over a range of frequencies.

18 PERFORMANCE CALCULATOR a* b* Color Information: Outdoor Reflected Color Due to potentially objectionable angle color, Guardian urges caution in using annealed or HT versions of SN 68 (herein referred to as "SN coatings") in laminated make-ups with the coating facing the interlayer, for large expanse facade applications. When SN coatings are laminated facing an interlayer material, including but not limited to polyvinyl butyral (pvb), the coating s reflected outdoor color, that is the color viewable from the outside of the building, will shift to a red or purple color when viewed from an angle. This color is most noticeable when viewed from a distance at an angle of 45 degrees or more. This color is noticeable with clear or low-iron float glass and the coating on the inboard-facing surface (i.e. Surface #2). It is even more pronounced with a clear or low-iron float glass as the outboard lite and a tinted inboard lite. If the architect, owner, glazier or fabricator elects to use these products in a glass makeup as described above, Guardian strongly recommends that full-size mockups be manufactured and approved in writing prior to proceeding. I have read and understand this information and agree to secure written mock-up approval prior to proceeding with any glass make-up covered by this advisory.

22 Process Equipment Highlights New to the 2016 Energy Standards are mandatory energy saving requirements for escalators and elevators. Acceptance testing will be required for controls requirements. Escalators and Moving Walkways Section 120.6(g) Escalators and moving walkways will be required to run at lower speeds when unoccupied (and thus a lower energy consuming state) while not in use in high traffic areas like airports, hotels, and transportation function areas. Elevators Section 120.6(f) Energy efficient lighting: Lighting Power Density (LPD) of 0.6 w/ft2 maximum Energy efficient fans: Ventilation fans for cabs without space conditioning shall not exceed 0.33 w/cfm Automatic shut-off controls on cab lighting and fans after 15 minutes of no service (stopped, unoccupied with doors closed) Lighting and ventilation must be operational during emergency stop situations while occupied with passengers. Mechanical Highlights Mandatory Equipment Efficiencies Section Mandatory equipment efficiencies for air conditioning units have increased as of 1/1/2016. Chiller and DX equipment efficiencies have become more stringent. Economizers Section (i) New mandatory requirements for Fault Detection and Diagnostics (FDD) on all economizers installed on new air-cooled packaged DX units with cooling capacity of 54,000 Btu/hr or greater. Stand alone or integrated FDD accepted per Section 120.2(i) of the 2016 Energy Standards. HVAC System Controls - Sections & Mandatory Direct Digital Controls (DDC): DDC shall be applied per Section 120.2(j) of the 2016 Energy Standards, Table A for new construction, additions, and alterations. Control logic must be capable of monitoring several points including fan pressure, pump pressure, heating and cooling, have optimum start/stop controls, and perform automatic information transfer among other requirements.

Prescriptive HVAC Shut-off Sensors for Windows and Doors: If windows or doors are left open for more than five minutes, sensors will adjust thermostats to disable the HVAC equipment by resetting the temperature setpoint to 55 F for mechanical heating and 90 F for mechanical cooling. Exemptions for doors with automatic closers or any space without thermostatic controls. Requirements per Section (n) of the 2016 Energy Standards. Commissioning Highlights A few important clarifications were made to the commissioning requirements in Section of the 2016 Energy Standards: Commissioning is required for all new buildings with nonresidential conditioned space, including nonresidential spaces in hotel/motel and high-rise residential buildings. The Owner s Project Requirements (OPR) must include building envelope performance expectations under the 2016 Energy Standards. Section in Part 1 specifies that the Design Reviewer may be a licensed architect or licensed contractor in addition to a professional engineer. Indoor Lighting Highlights The interior lighting mandatory and prescriptive requirements, as well as updates to the calculation methodologies are included below. Prescriptive Calculation Methodology Section Complete Building Method: Allowed Lighting Power Densities are reduced by 0.1 or less for half of building types listed in Table B. Area Category Method: Allowed Lighting Power Densities are reduced by 0.2 or less for a third of functional areas in Table C. Tailored Method: Lighting Power Density Values updated per Table G. Allowances in Table D remain unchanged. Indoor Lighting Controls Sections & Mandatory Shut-OFF Controls: Additional exception of 0.1 w/ft2 for egress in any building. Mandatory Multi-level Controls: Enclosed areas 100 ft2 or greater with a general lighting load greater than 0.5 w/ft2 must have multi-level controls as shown in Table A. Some exceptions apply for classrooms, public restrooms, and areas with one luminaire. Mandatory Partial-ON Occupancy Sensor: For areas requiring occupant sensing controls per Section 130.1(c)5 of the Standards (offices 250 ft2, multipurpose rooms < 1,000 ft2, classrooms, and conference rooms), and multilevel controls per Section130.1(b)of the 2016 Energy Standards, the occupant sensing controls shall function as partial-on (for 50-70% of controlled power) OR vacancy sensor (only manual ON). Where no multi-level controls are required per Section 130.1(b) of the 2016 Energy Standards, an automatic full-on occupancy sensor is acceptable. Control Credits: Power Adjustment Factors (PAF) listed in Table A have been updated and the following options have been added: Institutional Tuning: Limits maximum output or power draw of controlled lighting to 85% or less of full light output/draw. Daylight dimming plus OFF control: Turns lighting completely OFF when daylight in the daylit zone is greater than 150% of general lighting system at full power.

23 Lighting Alterations The lighting alterations language for the prescriptive approach is included in the following sections. Lamp replacements or ballast replacements alone are not considered lighting alterations, provided that replacement lamps and/or ballasts are installed and powered without modifying the luminaire. Entire Luminaire Alterations Section 141.2I Lighting shall meet the lighting power allowance in Section of the 2016 Energy Standards and altered permanently installed luminaries shall meet the applicable requirements in Table E if the following options occur: Removing/reinstalling 10% or more of the existing luminaires (if there are more than 2) in a space, or Replacing or adding entire luminaires, or Adding, removing, or replacing walls or ceilings along with lighting redesign (changing the area or space type) When replacing existing luminaries and the alteration is not in conjunction with adding, removing or replacing walls or ceilings, the new luminaries must: Reduce rated power by 50% for office, retail and hotel occupancies and 35% for all others, compared to the original luminaires, at full light output, and Meet all the requirements in Sections listed in Lighting Alterations (see list below) Luminaire Component Modifications Section 141.2J Definition: Alterations that replace the ballasts or drivers and the associated lamps in the luminaire, or permanently change the light source or the optical system of the luminaire. Modifying the components of fewer than 70 existing luminaires on a single floor or within a tenant space within a year, does not trigger code. If there are 70 or more modifications per year on a single floor or tenant space, then the project needs to meet one of the following criteria: Meet lighting power allowance in Section of the 2016 Energy Standards, and comply with Table E or Reduce rated power by 50% for office, retail and hotel occupancies and 35% for all others, compared to the original luminaires, at full light output, and meet the requirements in Lighting Alterations Sections List. In addition, the modification should not prevent or disable multi-level, shut-off, or daylight controls. Lighting Wiring Alterations Section141.0(b)2K Definition: Alterations that add a circuit feeding luminaires, that replace, modify or relocate wiring between a switch or panelboard and luminaires, or replace lighting control panels, panelboards, or branch circuit wiring. Wiring alterations (unless strictly to add lighting controls) in each enclosed space shall meet the requirements in the following sections: Lighting Power Allowance in Section Section (a) 1, 2 and 3 Section (c)1a through C Section (c)3 and Section (c)4 And meet the following criteria: Each enclosed space must be wired to create a min. of one step between 30-70% of the lighting power or meet Section 130.1(c)4 of the 2016 Energy Standards. For each enclosed space where alterations include 10 or more luminaires that provide general lighting and are located in the primary sidelit daylit or skylit daylit zone, also meet the requirements of Section 130.1(d) of the 2016 Energy Standards. Exceptions for all lighting alterations: Alterations that would cause the disturbance of asbestos. Alterations affecting two or fewer luminaires in an enclosed space. Lighting control acceptance testing (per Section of the 2016 Energy Standards) is not required for alterations of a total of 20 or fewer controlled luminaires.

24 Outdoor Lighting Highlights Outdoor Lighting Zone 0: New lighting zone added for undeveloped areas of state or national parks. No continuous hardscape lighting allowed. A single luminaire of 15 watts or less may be installed in certain areas. Hardscape Lighting Power: Several reductions in lighting allowances have been included in Table A, for each lighting zone (LZ). Additional wattage allowances are applicable for instances where hardscape is more than 50% concrete in LZ2 and LZ3. Specific Applications in Lighting Power: Lighting power allowances for building entrances/exits for LZs 1-4 have been reduced (Table B). Lighting for ATM machines is now 250 watts for the first ATM and 70 watts for each additional machine, across all LZs. Motion Sensors: Motion sensor capabilities must be able to reduce lighting power of each luminaire by at least 40% but not exceeding 90%. Sales lots and sales canopies are no longer exceptions under Section130.2(c)3 of the 2016 Energy Standards. Outdoor Lighting Alterations Section 141.0(b)2L Alterations to existing outdoor lighting shall meet the mandatory requirements in the following sections in the 2016 Energy Standards: Section Section 130.2(a) and (b) Section For alterations that increase the connecting lighting load: Added or altered luminaires must meet the applicable requirements in 2016 Energy Standards of Section 130.2(c) and the requirements of Section for general hardscape lighting or for the specific lighting applications contained the alterations. For alterations that do not increase the connecting lighting load but where the greater of 5 luminaires or 10% of existing luminaires are replaced, the following requirements apply: Parking lots/ outdoor sales lots: For replacement of luminaries mounted 24 ft or less above the ground, alteration must comply with Section 130.2(c)1 and Section 130.2(c)3 of the 2016 Energy Standards. For all other applications (except parking lots/outdoor sales lots) and where the replacement luminaries are mounted above 24 ft (parking lots & sales areas), alteration must comply with Section 130.2(c)1 and either Section 130.2(c)2 or be controlled by lighting controls (motion sensors) that automatically reduce power by 40% when unoccupied. For alterations that do not increase the connecting lighting load but where the greater of 5 luminaires or 50% of existing luminaires are replaced, the following requirements apply: Must meet all above requirements for 10% replacement Section (except when alterations reduce power consumption by 40% compared to the original luminaires) Exceptions for all lighting alterations: Lighting control acceptance testing (per Section of the 2016 Energy Standards) is not required for alterations of a total of 20 or fewer controlled luminaires.
