OP-11: Sustainable Procurement

Each project requires different analysis. We use engineering economics to analyze energy and water-using products and systems. Looking at these costs: Initial Costs—Purchase, Acquisition, Construction Costs Fuel Costs Operation, Maintenance, and Repair Costs Replacement Costs Residual Values—Resale or Salvage Values or Disposal Costs Finance Charges—Loan Interest Payments Non-Monetary Benefits or Costs After analysis, we choose the option with the lowest total life cycle cost and lowest environmental impact.

CAPITAL DEVELOPMENT PROJECTS MANUAL https://www.maricopa.edu/sites/g/files/vmcrws441/files/pdf/fpd/MCCCD_General_Design_Guidelines.pdf 3.1.8 Sustainability, energy and water conservation As a large user of energy in the operation of its facilities, the District is extremely conscious of the need to minimize its consumption of energy and water. This requires a comprehensive, interdisciplinary approach to energy and water efficient design. Examples include the use of native, drought-tolerant vegetation in landscaping, proper building orientation, adequate but protected fenestration, appropriate design and performance of mechanical systems, etc. 3.2 Sustainable Buildings All new college buildings and renovation projects should be designed to meet general sustainable building principles and ―green building criteria where practical to do at reasonable costs and investment return. A properly designed, sustainable building reduces energy and water use, wasted resources and provides a healthy working and learning environment for our users. While a certified LEED Silver rating will not be required of any District facilities, energy and water conservation and other issues of sustainability should be explored for each project. Use of local materials, low water use landscaping and plumbing fixtures, construction waste management, recycled content in new materials, low emitting materials, daylighting techniques, along with energy and water conservation are principles that can be evaluated and applied. The design and construction team should consider LEED Silver Credit categories and concepts that can be achieved with relative ease and be pursued to the extent that such measures provide meaningful benefits to the building projects, occupants, operators, or the environment within the project budget. 3.3 Energy Conservation Design Criteria 3.3.1. Building Envelope The envelope specifications will adhere to the prescriptive standards listed in ASHRAE 90.1-2004. Alternatively, the designer may follow the directions for the use of a computer simulation under the Energy Cost Budget section of ASHRAE 90.1-2004. 3.3.2 Roofing Materials – Reflectivity Roofing products should follow the concepts of, and where appropriate, comply with the technical specifications of the U.S. EPA’s Energy Star labeled Roof Products. 3.3.3 Lighting Fluorescent lighting shall be T-8 tubes with electronic ballasts or better. T-5 tubes and technology may be used in completely new locations where no integration with existing T-8 systems is required. Occupancy sensors with manual override will control all interior lighting. All exterior lighting should operate through time clocks or the energy management system on campus. No lighting should be operated through circuit breakers in the panels only. Exit signs shall be LED. Other light fixtures that typically use incandescent light sources should use PL tubes when equivalent or better lighting levels can be achieved. 3.3.4 HVAC Systems and Controls Each classroom or meeting room is to be served by a single VAV box. Up to four offices may be served on a single VAV box where similar exposures and loads may be expected HVAC controls shall switch between unoccupied and occupied modes based on tying into occupancy sensors or scheduling. 3.5. Building Configuration Attempt to minimize the ratio of surface area of walls and roofing to gross building area in order to reduce heat loss and/or heat gain within reasonable design considerations. Configuration of floor plans should strongly consider maximizing the number of areas the mechanical equipment serves by minimizing the quantity of mechanical systems required to support those spaces, again within reasonable design considerations. 3.6. Glazing and Infiltration Use appropriate glazing systems to minimize heat gain and reflected glare to adjacent buildings or public areas. The use of projections and roof overhangs over windows is recommended in sunny locations and particularly on south and west orientations. The length of the projection should be calculated to maximize solar gain in winter and shading during the late spring/summer/early fall, the times of heaviest internal and external loads. This function may also be achieved by using fixed awnings or other architectural devices. Avoid use of highly reflective or mirrored glass. All exterior windows should be double glazed, insulated units. All exterior doors shall be weather stripped, including door thresholds. 3.7. Environmental Issues Environmental issues that must be addressed in the early planning stages of a project. In these situations, risk management and campus safety requirements must be considered. Of the greatest concern are: environmental regulations imposed at the local, state and federal levels pertaining to air and water quality requirements and considerations be given to atmospheric emissions and discharges to storm and/or sanitary systems storm water retention and run-off, along with dust control, during construction handling of solid and hazardous substances, including their disposal good HVAC system design that provides a high level of air quality in the building If hazardous materials (asbestos, lead, PCB’s, mold, etc.) are suspected or discovered during either the design or construction phase immediately notify the PM. The District will provide testing and abatement as the situation requires. CGCC follows LEED Silver standards when evaluating construction and renovation products.

All purchases are Energy Star and EPEAT Gold certified.

Architects and engineers need to follow LEED guidelines for efficient building design. LEED guidelines attached.

MARICOPA COMMUNITY COLLEGE DISTRICT PURCHASING PROCEDURES MANUAL https://ep.maricopa.edu/business/purchasing/Shared%20Documents/New%20Purchasing%20Manual_3_19_2019.pdf Appliance Purchases As one of many actions in support of the American College and University Presidents' Climate Commitment, only Energy Star rated appliances and equipment will be purchased, if available. This means that even if a non-Energy Star appliance is less costly, the Energy Star rated appliance will be purchased.
