Project Overview Boeing is accelerating improvements in the environmental performance of the company’s operations as business continues to grow. Within the walls of our factories and offices, we continue to accelerate improvements in environmental performance. After achieving our first five-year set of absolute-reduction targets, we are committed to zero growth in water consumption, greenhouse gas emissions, hazardous waste and solid waste to landfill. Boeing designs all new construction and major renovation projects to meet a LEED Silver rating or higher. The Boeing Murray Park Building Expansion is targeting LEED Silver Certification. Boeing Winnipeg is one of the largest aerospace composite manufacturers in Canada. The company employs over 1,600 people in 67,820 square meters of space in two locations in the city. The project is located in the fully developed Murray Industrial Park in Winnipeg, Manitoba. Boeing Winnipeg produces nearly 1,000 end item composite parts and assemblies for Boeing Commercial Airlines. Major products include wing to body fairings, engine strut forward fairings, engine strut aft fairings and landing gear doors. Boeing Winnipeg is a Tier 1 partner to the 787 Dream liner program. The Murray Park Building Expansion project includes a building addition of 14, 939 square meters at the west end of the building to support our additional fabrication work statement. The new building matches the existing building in terms of construction material, building height, and occupancy. The expansion houses an open manufacturing space, a controlled contamination room, shipping and receiving areas and docks, and office space. The expansion also included an extension of to the northeast side of the existing parking lot. The project is targeting LEED Silver certification.

Design Boeing Design Criteria LEED: The Design Builder was mandated to pursue LEED Silver certification through the Canada Green Build Council. Environmental and Sustainability Goals:

• Conduct operations in compliance with applicable environmental laws, regulations, and Boeing policies and procedures.

• Prevent pollution by conserving energy and resources, recycling, reducing waste, and pursuing other source reduction strategies.

• Continually improve our environmental management system. • Work together with our stakeholders on activities that promote environmental protection and

stewardship. • A comprehensive Integrated Design Process (IDP).

Integrated Design Approach Predesign Phase: An intensive 2 day design charrette was conducted to determine project goals and knowledge base thereby setting the ground work for decision making. A Charter Agreement was initiated by setting out objectives together with the client, user, and consultant team. This Charter was further refined at subsequent IDP meetings until everyone was satisfied and signed on several months later. The charter would become a touch stone later when value engineering options were vetted in order to meet the project cost threshold. This was followed up by an energy charrette a week later that furthered the design approach to include the exploration of improved energy performance opportunities, goals and targets. Key targets identified included the pursuit of measurement & verification and enhanced commissioning. Design Phase: Consultants prepared for a new level of evaluation at each meeting circling inward from massing, orientation to the passive building design (skin, glazing, shading, daylighting, glazing ratios etc.), to the more active energy systems. Comparative analysis of systems became a focus at several meetings to vet the pros and cons of each system. Throughout the process, the architectural design was fully collaborated with that of the other building engineering design disciplines. The building design methodology incorporated sustainable criteria to targeting LEED silver minimum requirements. Weekly meetings between Stantec and Boeing served as collaborative opportunities for design discussion and a high level of owner involvement. Design options were developed by Stantec for presentation to and consideration by Boeing. Through this approach, a high degree of “informed client consent” was reached. Energy modeling was used throughout the IDP process to guide decision making on a range of system combinations.

Sample Energy Savings resulting from each Energy Conservation Measure at Schematic Design Siting The expansion was located to the west of the existing Murray Park facility. The existing guard house remained in its location during and after building expansion construction. The roadway was modified to suit the building expansion and maintain the guard house. The existing landfill site and control zone to the north was not disturbed. Selective demolition was required to accommodate the building expansion. Plans were produced to identify components to remain, or be salvaged, as well as what components were to be removed. Salvaged material remained the property of Boeing. Removed material was to be disposed of off-site with every effort made to divert the material from the landfill. Boeing EHS reviewed and approved all material being removed from site. The existing building stayed functional while the expansion was under construction. Portions of the existing west wall were penetrated to provide connection(s) to the expansion. Existing building additions (lean-to shed) on the west end of the existing building was removed to make way for the expansion

New Addition FLOORS The process area, clean room, staging area and shipping and receiving area floors have exposed concrete complete with hardeners to a floor flatness level of FF25. Carpet tile manufacturers, standard colours and patterns have been selected for the office area and are compliant with LEED requirements. Washroom, housekeeping and other potentially wet areas have anti-slip epoxy flooring. CEILINGS The ceiling height to underside of the lowest exposed roof structure has a minimum clearance of 25’-0” in the process areas. The clean room area has finished washable ceilings. Office, meeting rooms, washrooms, etc. will have ceilings meeting code and Boeing standards. INTERIOR WALLS Interior walls have been designed with fire ratings as required by code and meet Boeing standards including those for sound transmission coefficient (STC) ratings. Higher acoustical treatment has been addresses between office area and high noise areas adjacent (plant equipment, mechanical room, etc.). Offices have demountable partitions for increased flexibility. EXTERIOR WALLS Exterior walls are a combination of double metal skin insulated panels (matching recent existing building construction) and concrete masonry unit for durability at floor/ground level. Walls are insulated to meet Manitoba Hydro Power Smart Requirements Envelope Performance Roof U-value

MECHANICAL/ELECRICAL DESIGN The building’s space heating is natural gas; energy strategies employed to reduce consumption include the following: Space Heating – Natural Gas

• Exhaust Air Heat Recovery – Heat is recovered from the exhaust air leaving the proposed building through an energy recovery device to preheat incoming outdoor air.

• High Efficiency Heating System – The building is served by a natural gas condensing boiler with an efficiency of 92%.

Space Heating – Electric The building’s space heating – electric energy use has reduced due to the following:

• Building Envelope – Electric heaters are located in the vestibule, stairwells and exit corridors. The thermal performance of the building’s exterior wall is allows a reduction in space heating.

Space Cooling/Heat Rejection The building’s space cooling / heat rejection energy use has been reduced due to the following:

• Reduced Internal Gains – The proposed building’s interior lighting power density is less than the reference building’s, thus reducing the load on the cooling plant.

• More Efficient Central Plant – The building is supplied with district chilled water from the existing chiller in the adjacent plant. The existing chiller has a COP of 6.2.

Interior Lighting The building’s interior lighting energy use has been reduced due to the following:

• Reduced Interior Lighting Power Densities – The building has a lower average interior lighting power density with the incorporation of LED’s (37% reduction).

• Controls – The building incorporates occupancy and daylight sensors which further contributes to interior lighting energy savings.

Exterior Lighting The building’s exterior lighting energy use has been reduced due to the following:

• Reduced Exterior Lighting Power Densities – The building has a lower average exterior lighting power density through the use of LEDs

Fans The building’s fan energy use has been reduced due to the following:

• Reduced Internal Gains – The proposed building’s interior lighting power density is less than the reference building’s, thus reducing the airflow requirements and the load on the fans.

Page 7: Boeing Winnipeg Murray Park Building Expansion LEED … · Boeing Winnipeg . Murray Park Building Expansion . LEED Design Case Study

• Lower Installed Fan Power – The building incorporates fans that have lower installed power requirements while also utilizing variable speed drives which helps to reduce fan energy at part-load conditions.

Pumps The building’s pumping energy use has due to the following:

• Variable Speed Drives - The building utilizes variable speed drives on all secondary hot water and chilled water pumps, which helps to reduce pumping energy at part-load conditions.

Service Water Heating – Natural Gas The building’s service water heating energy use has been reduced due to the following:

• High Efficiency Service Water Heating System – The building is served by a high efficiency natural gas water heater with an efficiency of 95%. The high efficiency service water heating system contributes to a reduction in service water heating energy use.

• Reduced Service Water Heating Flow Rates – The building utilizes fixtures that reduce the service water flow rates. This further contributes to energy savings associated with service water heating.

Humidifiers – Electric The building’s humidifier energy use has increased compared to the reference building due to the following:

• Increased Humidifier Load – The building has a minimum relative humidity requirement of 30% during the winter. As the building utilizes heat recovery to preheat the incoming outdoor air, this reduces the amount of relative humidity in the outdoor air, thus increasing the load on the humidifiers.

FUTURE EXPANSION Future development was a consideration in the overall design of the facility; the structure and exterior wall have been designed to accommodate expansion. The mechanical and electrical design was not sized for further expansion and will have capacity for the current expansion only. The following design characteristics have been incorporated to achieve a flexible space:

• increased column spacing; • vacuum, and compressed air, have appropriate tees; • ample electrical panels have been provided throughout the plant to avoid long wire runs. • 25ft ceiling clearance throughout the factory; • and, receptacles are located at the ceiling for high bay lighting.

Sustainable Sites The site is located on a previously developed lot in an industrial area of the city. Bike racks and changing facilities have been provided to reduce transportation impacts. Electric vehicle stations have been installed for 3% of the total vehicle parking capacity of the project. Boeing recognizes the that the advantages of owning an electric vehicle are numerous especially in Manitoba where we have the benefit of hydroelectricity which translates directly into fuel savings, not to mention savings on maintenance costs and repairs. Making the switch to electric vehicles strengthens Manitoba’s energy independence by enabling us to move away from imported fossil fuels and subsequently lowering environmental impacts through a reduction in emissions.

Heat island effect has been addressed through the use of a high albedo roof; the impact on microclimates and human and wildlife habitats has been minimized in addition to helping mitigate cooling loads.

Exterior lighting has been designed to minimize light pollution and trespass from the building and site. With the construction of a new parking lot and entrance to the site in 2013, the Winnipeg team took advantage of the rapid improvements in light-emitting diode (LED) technology to upgrade some of its lighting features. Providing 34 percent more coverage, only 45 LED light fixtures were necessary to cover the 700-stall, 272,575-square-foot (25,323-square-meter) lot, reducing the number of light fixtures required by about half. Lower maintenance costs, longer life and superior energy efficiency all translate into lower energy requirements and costs.

The LED lights (the white lights in background) used for the new parking lot in Winnipeg, Manitoba, Canada, make a measurable difference in lighting and energy savings, compared to the existing lights (orange-yellow lights in foreground). (Boeing photo)

WATER EFFICIENCY The water efficient landscaping – no potable water use/no irrigation approach was used for the project. All trees, shrubs and plants installed required no establishment watering beyond one year. Smaller size tree and shrubs were chosen to minimize the transplant shock effect resulting in healthier plants. The smaller trees and shrubs require less water volume per plant, and thus less initial maintenance/watering time. Plants establish themselves more rapidly as a result of less transplant shock and requirement for water volumes. The majority of the shrubs are located on the north side of the building, thus further reducing the amount of water required by each plant. Shade tolerant plants were chosen for those locations. All planting beds are covered with a wood chip mulch to reduce the amount of evaporation, and to conserve any rain moisture within the ground. A local drought tolerant sod was utilized and does not require any watering once rooted, which is typically 30 days. In drought conditions the sod will go dormant and rejuvenate with the return of moisture/rains. Some existing grassed areas within the LEED footprint, will be retained where possible, to lessen the amount of new landscape materials required, and initially watering establishment time period. A water use reduction of 36.24% over the baseline case was achieved through:

• Tankless, flush valve type water closets; • Ultra-low flow urinals; and • Automatic (hands-free) activation for lavatories, water closets and urinals.

Energy and Atmosphere Boeing recognizes building commissioning as a quality process that completes the circle in the construction cycle verifying that the design and equipment work as intended. Both fundamental and enhanced commissioning has been pursued. The role of the Commissioning Authority consultant (CxA) is to act on behalf of Boeing to oversee the commissioning process to confirm:

• commissioning is properly planned and executed; • complete documentation is provided to the Owner such that operating staff can use it to operate

and maintain the facility to provide optimum life cycle costs for the plant, • all operating personnel are fully trained, with an understanding of how to start, operate and stop

all equipment and systems safely, under both normal and emergency conditions, and • system performance is verified to meet the design parameters set out for it by the designer, and

appropriate documentation is produced to record the results of the verification tests. Building Performance - The Energy Model The energy reduction targets for this highly energy consumptive building type influenced many aspects of the design. Architecture and structure were developed to contribute to energy efficiency and waste reduction.

Figure 1: IES VE Model Rendering of the Boeing Murray Park Building Expansion The purpose of the energy modelling is to demonstrate compliance with EA prerequisite 2 Minimum Energy Performance, and determine the number of LEED points achieved for EA credit 1 Optimize Energy Performance.

Performance – Refrigerant Management Refrigerants and heating, ventilating, air conditioning and refrigeration (HVAC&R) that minimize or eliminate the emission of compounds that contribute to ozone depletion and global climate change have been selected. The fire suppression system for the plant is composed of a wet pipe sprinkler system and dry chemical fire extinguishers, none of which utilize CFC-based refrigerants Performance – Measurement and Verification A measurement and verification (M&V) system has been installed in the Boeing Canada Operations building expansion project at 99 Murray Park in Winnipeg, Manitoba. The key HVAC systems, lighting systems, process equipment and energy conservation design features are described and the recommended metering points indicated. This measurement and verification (M&V) plan is developed as required in LEED Energy and Atmosphere Credit 5 (EAc5), and customized to suit the building design and owner requirements. Energy savings from energy conservation measures (ECMs) incorporated into the building design will be metered, and the data will be stored and ultimately compared to the expected savings calculated from the LEED EAc1 energy model of the building. Through this comparison, the performance of the building’s energy conservation features can be verified and demonstrated. Any deviations from the expected performance will be addressed through a plan for corrective action. The data gathered from the measurement and verification system may also be used for optimizing the ongoing operation and eventual re-commissioning of the mechanical and electrical systems.

Materials Boeing Canada Winnipeg has implemented a recycling waste management program throughout its facilities, including manufacturing, cafeteria and office areas. In 2014, BCW received numerous new recycling bins from Recycle Everywhere, part of the CBCRA. Environment Health & Safety is now working to standardize all of BCW’s recycling and waste bins to make it easier for employees to separate waste and maximize on diverting waste from the landfill.

• Plastics recycling are collected throughout the facilities in many different forms. Plastic bottles and containers from food and beverages are collected in mixed recycling bins which are placed throughout the facility in office areas, meeting rooms, cafeteria and kitchenettes. Other miscellaneous plastics are also collected in bins and sent to recycling.

• Metals are collected from Maintenance, Moonshine, Tooling and Assembly areas, as well as from other miscellaneous projects. Metals are sent to a company which specializes in metal recycling.

• Wood is mostly comprised of pallets and crates from our Shipping & Receiving departments and sent to a facility to recycle/reuse.

• Cardboard is collected in bins throughout the facility and brought to the cardboard compactor for recycling.

• Composting is collected in the cafeteria kitchen. BCW has procured triple stream bins for the cafeteria comprised of compost, recycling and landfill waste. The intent of these bins is to encourage employees to sort their waste.

• Paper is disposed of in Iron Mountain secure shredding bins located throughout the facility. Iron Mountain recycles this paper at their facility.

• E-Waste is collected and disposed of with BCW’s hazardous waste contractor who sends the waste to GEEP. The E-Waste is responsibly recycled and re-used as much as possible. BCW doesn’t have a large amount of e-waste due to computers being sent back to the supplier and most ink cartridges as well. GEEP is a Boeing-approved Treatment Storage and Disposal Facility (TSDF) which means they have gone through an on-site audit by Boeing Enterprise EHS personnel.

• Landscape waste is composted by the landscape Contractor.

Page 15: Boeing Winnipeg Murray Park Building Expansion LEED … · Boeing Winnipeg . Murray Park Building Expansion . LEED Design Case Study

A construction waste management plan was developed by Graham Construction who was committed to reducing and responsibly managing the waste generated by the construction process of the project through management procedures that included:

• Ordering accurate material quantities • Using prefabricated assemblies where possible • Enforcing Supplier/Subtrade take-back of packaging and unneeded components • Instructing Subtrades to prevent damage to material as a result of mishandling, improper

storage/protection, or exposure to contamination (fumes, weather, dust, chemicals, etc.) • Instructing and monitoring Subtrades and site workers on proper material installation to

maximize use, and to minimize cutting, replacement or other modification • Identifying opportunities to reuse, donate and/or share materials

Concrete and Asphalt Maple Leaf Road Base Fill 98.5% of construction waste was diverted from the landfill. Sustainably sourced materials such as those containing high amounts of recycled content, regional value were sourced and installed where possible. A durable building plan was developed to aid designers, construction trades, and operational and maintenance staff minimize material use and construction waste during the design, specification, construction and operational phases of the building. Selecting materials that are low maintenance, have minimal environmental impact, and are compatible with each other are key elements of the durable building plan were of utmost importance to the Project Team and Owner. The following items were identified and addressed:

• Discussions with the Owner to determine the required design service life based on intended use, cost, and frequency, difficulty of maintenance and repair. The design service of the building provides one basis for the determination of design service life of the building envelope components;

• Discussions concerning environmental factors (e.g., precipitation, wind, temperature, humidity) that affect the durability of the building envelope with regard to aging, wear and anticipated lifespan of components and materials in Southern Manitoba;

Indoor Environment Environmental concerns regarding construction methods, use of local materials and knowledgeable trades people in the neighbourhood/community; and, Strategies to maintain the predicted service life of the building and its components.

Indoor Environmental Quality Environmental initiatives are embedded into every organization and function within Boeing. The EHS (Environment, Health & Safety) organization works with our business units and operational leaders to drive an integrated, enterprise wide strategy that includes our products, services, processes and operations. The EHS organization also contains functions focused on workplace safety and health, environmental performance and regulatory compliance. In regard to indoor air quality performance, the majority of the plant, excluding heating-only zones (e.g. vestibules, autoclave areas) is served by multiple zone recirculating systems, composed of energy recovery ventilators (ERV), central air handling units (AHU), reheat coils and variable air volume (VAV) terminal boxes. The office mezzanine, served by AHU-1, is the only variable air volume system within the plant. The north half of the plant is served by AHU-2. Both AHU-1 and AHU-2 receive their ventilation air through ERV-1. The “clean room” (actually a controlled environment rather than an actual clean room) is served by AHU-3. The south half of the plant is served by AHU-4. Both AHU-3 and AHU-4 receive their ventilation air through ERV-2. The air handling units supply tempered (55°F) air to conditioned spaces throughout the year, which is reheated at the zone level as required by hydronic reheat coils, unit heaters and in-floor heating in the winter to account for envelope heat losses. Tobacco smoking is prohibited within the Boeing plant and limited to a shack located on site well away from the building. Signage has not been posted but rather addressed to staff through Boeing Company Canada Rules and the visitor orientation process. Poor indoor air quality has been associated with sick building syndrome, absenteeism, reduced performance, and low morale. Airborne particulates can aggravate existing asthmatic conditions, and lead to respiratory issues. Many volatile chemicals induce headaches, fatigue and nausea when occupants are exposed to them over time. Key IAQ Management Plan objectives during construction included:

• Reduce indoor air quality impacts from construction and renovation • Ensure comfort and safety of construction workers and building occupants • Use products and materials that minimize air pollutants (dust, debris, fumes, etc.) • Use construction methods and techniques that minimize air pollutants • Protect HAVC equipment, ducting, and porous materials from dust and debris during

construction/renovation • Ensure air handling systems are clean prior to startup • Ensure sites are kept clean throughout construction and prior to handover

The inspection & reporting process was integral to the overall IAQ management plan:

• Graham Site Representative to perform daily inspection of building and site IAQ controls • Graham Site Representative to perform weekly IAQ monitoring and reporting • Required photographs of SMACNA IAQ guidelines to be submitted with the IAQ Report • Any breach by a subcontractor was documented and issued as non-compliance.

Baseline IAQ testing was conducted after construction ends and prior to occupancy to demonstrate that concentrations of targeted contaminants are not exceeded. Testing was performed by a qualified designate in compliance with the requirements of LEED, the US Environmental Protection Agency Compendium of Methods for the Determination of Air Pollutants in Indoor Air and CaGBC Credit Interpretation Request CIR505 (13 April 2010). To ensure the optimal indoor air quality all finishing materials installed within the building were specified and sourced to be low VOC emitting products. This included paints, coatings, adhesives, sealants and carpet.

The Boeing expansion at Murray Park consists of a 13,935 sq. m. plant floor for building aircraft parts and 492 sq. m. administration spaces. The approach in providing controllability of systems- lighting necessitated the consideration of the two distinct occupant types: Individual and Group Multi-Occupant space classifications. The primary space of this facility is the Plant Floor, this area is a large open space utilized to build large pieces of equipment. This space is homogenous, and therefore having individual lighting controls for the occupants would not be feasible. In reporting this space we have classified the Plant Floor to be a multi-occupant space with four lighting controls that are on multiple circuit on/off panels. The four panels control four lighting zones and are available to the plant personnel and are located in the respective zones of the plant floor. A central lighting control system is also tied to these panels so that the building manager has overall control for building systems' optimization. The locations of the light control panels can be seen on drawing E2 and within the attached, where the lighting zones and panel locations have been indicated. The main level of the facility contains a Multi-Purpose Room that is classified as a Group Multi­ occupant space. Users of this space have the ability to turn lights on or off, along with dimming capabilities as required through wall mounted switches. The second level contains office space that is separated in terms of open office space and private offices. Each of these areas is classified as an Individual space, and therefore the occupants are required to have accessible lighting control. In keeping with the credit requirements, each private office is equipped with a wall mounted occupancy sensor with a manual override, and each workstation in the open office area is equipped with task lighting. The meeting and collaboration rooms, are both multi-occupant spaces, and are controlled through wall mounted switches that can provide dimming capabilities and/or motion detection with manual overrides.

Innovation in Design Boeing Winnipeg has implemented a solid waste management policy to reduce the amount of waste and toxins that are hauled to and disposed of in landfills or incineration facilities. This policy aligns with and supports Boeing’s Environmental Policy. This policy covers both 99 Murray Park Road and the 1345 Redwood Avenue facilities that comprise Boeing Winnipeg. This policy applies to the disposal of all materials at Boeing Winnipeg, including ongoing consumables, durable goods, and materials/products related to facilities alterations and additions. This policy will affect facilities staff and all building occupants. The goals of this Solid Waste Management Policy include: Monthly targets for solid waste generation are estimated annually and submitted to Boeing Corporate for approval by the site’s Environmental Specialist in cooperation with all necessary stakeholders (responsible parties). Performance is based on meeting the estimated targets for tons of solid waste disposed per month. The policy covers:

• Ongoing Consumables • Durable Goods • Facility Alteration and Addition Materials

Boeing Winnipeg has established active contracts with hauling facilities and waste vendors who provide detailed reports and/or invoices about the quantities of waste and recyclables that are removed from the facilities.
