MECHANICAL CONCEPTS

• Light pollution reduction - Design of exterior light fixtures with proper photometric distribution and control to eliminate light trespass. • Optimize Energy Performance - Lighting design featuring efficient LED fixtures throughout the spaces. • Renewable energy - Incorporation of renewable energy such as photovoltaic systems in a practical application. Specify only non-CFC-based HVAC system with lowest Global Warming Potential and least risk of fire hazard. (R12 and R22 not allowed). • Provide 100% air-side economizer and water-side economizer with thermal storage to increase efficiencies with lower wet-bulb temperatures. • Provide minimum ventilation for occupied space based on 0.15 cfm/sf or 15 cfm/person, whichever is larger. • Provide Indoor Air Quality (IAQ) control to be WELL-building ready • Include Commissioning Requirements in Construction Documents. Air-leakage prevention at all levels: Architectural construction details, caulking of duct systems, and proper sealants to all spaces. • Mechanical Units are selected to minimize power use and maximize capacity. Typical conditions are switched for the right conditions. •
