Previous scope

New High Performance “Green” Laboratory Building (82,000 square feet) Sustainable Design and Building Energy Efficiency & Conservation Features under consideration include:

Smart Growth Principles, Central Geothermal Heat Pump, Vegetated Roof, Water Conservation Strategies, Solar Orientation & Shading, Day Lighting, Building Integrated Photovoltaic, Natural Gas Powered Fuel Cell, Demand Control Ventilation, & Exhaust Heat Recovery.

Design will be compared to a baseline building that complies with the minimum requirements to meet ASHRAE 90.1, 2001 and 2007. Our design goal is to achieve 50% improvement over code. Comparing performance measures and cost to the baselines will guide our decision-making for building systems selections. Lifecycle cost of systems, optimizing performance and right-sizing design are important elements of how we will reach the best integration of architectural and engineering design. To organize our green lab design we will document our goals, strategies and performance using LEED criteria. A preliminary assessment indicates we could reach gold or platinum level certification. The following are guiding statements for each category:

LEED & Lab 21Sustainable Sites (SS). Incorporate features that promote use of alternative transportation (preference parking, bikes & public transit). Building and site design features and construction procedures will demonstrate practices that are low impact to the environment (e.g., storm water management, SRI >29, vegetated roof, and light pollution controls).

Water Efficiency (WE). Reduce water consumption (e.g., storing rain and gray water for site irrigation; reduce potable water use 30-40% over a LEED baseline; reduce lab process water and wastewater by 20-30%). Select HVAC systems that conserve water.

Energy & Atmosphere (EA). Reduce energy consumption through conservation measures to reduce load (e.g., orientation, day lighting, shading devices , insulation, materials & systems selection). Provide alternative energy options and peak demand management solutions.Right-size lab equipment and HVAC systems. Pursue ventilation efficiencies. A M&V plan will be used in commissioning the building to optimize performance. Evaluate possible elimination of refrigerants.

Materials & Resources (MR). Recycle construction debris and select materials with recycled content. Select regional materials within 500 miles of the project. Incorporate materials considered rapidly renewable and wood products that are certified FSCP&C. Develop a chemical and hazardous materials M&V management plan.

Indoor Environment Quality (EQ). Develop & implement an IAQ management plan for construction and preoccupancy. Optimize the building for comfort and performance as part of sustainable facility management procedures. Provide daylight and views to all regularly occupied spaces. Provide lighting controls to occupants. Select low-emitting materials (e.g., adhesives, sealants, paints, coatings, floor materials…). Use small control zones for laboratory hoods & optimize airflow.

Innovative Design (ID). Seek and document new strategies to enhance design outcomes.

Regional Priority (RP). Restore and protect natural habitats. Control the quantity & quality of storm water. Utilize on site renewable energy and manage construction waste.

Green power is derived from solar, wind, geothermal, biomass or low-impact hydro sources. Visit www. green-e.org for details about the Green-e program. The power product purchased to comply with credit requirements need not be Green-e certified. Other sources of green power are eligible if they satisfy’ the Green-e program’s technical requirements. Renewable energy certificates (RECs), tradable renewable certificates (TRCs), green tags and other forms of green power that comply with Green-e’s technical requirements can be used to document compliance with EA Credit 6 requirements.
