Reducing Energy, Carbon and Costs December 2012 Dan Watch, AIA, NCARB, LEED AP Vikram Sami, LEED AP
Architecture 2030 By the year 2035, approximately three-quarters (75%) of the built environment will be either new or renovated. This transformation over the next 25 years represents a historic opportunity for the architecture and building community to avoid dangerous climate change.

Improving Work HabitsAdjust the Thermostat • Lower the thermostat 10-15 degrees for 8 hours or more at a time. • In many cases, each degree increase in the heating set point increases energy use by 3%. • Chinese Codes 64-76 degrees • www.energysavers.gov http://green.harvard.edu/labs/workspace WARMERin the SUMMER > 75 F 72 F < 68 F COOLER in the WINTER
Improving Work HabitsLab Use Habits COMPUTERS: • Enable Desktop Power Management (putting computers to “sleep” can save over 75% in energy costs) • Utilize a Print Management System (typically results in 20-30% reduction in printer usage)
Improving Work Habits Lab Use Habits FUME HOODS: • SASH DOWN when not in use. • Disable or Remove unused Fume Hoods • Standard 6’ constant volume hood uses over 35,000 kWh/year in chiller and fan energy. • Combination Sashes • Air volumes reduced by up to 40% over traditional sashes. • Large energy savings. • Familiarity a hurdle sometimes.
Improving Work Habits Lab Use Habits BIOSAFETY CABINETS: Exhausted $2100 Recirculating $240
Improving Work Habits Just in Time Inventories From this…. To this….. • Sort and Recycle: Take inventory to determine if everything is still necessary. • Label and Store: Label all supplies and store them in a consistent location. • Standardize: The bench size with mobile casework.
Purchase Efficient Lab Equipment LED Lighting
Purchase Efficient Lab Equipment Freezer Specimen Storage LOW TEMP FREEZERS: • Inventory and Discard- Grad Students • Defrost and check seals frequently • Pack samples efficiently • Share freezers between labs • Larger units typically more efficient Elimination of one -80 freezer = $1,000+ savings in energy cost per year (does not account for additional heating load, maintenance and space used) Room Temperature Storage http://medfacilities.stanford.edu/sustainability/downloads/RoomTempStoragePilotResults.pdf
Purchase Efficient Lab Equipment Efficient Mechanical Duct + Plumbing Pipe Design Traditional 90 degree pipe connections create unnecessary friction and increased energy consumption. Instead, use: • Bigger Pipes, Smaller Pumps • Gentle Bends, No 90% Bends • Shorter Pipes (design pipe layout first, then add equipment they connect) Use of these strategies have led to a 75% decrease in pumping energy with a 1-2 month payback period.
Purchase Efficient Lab Equipment Plug Load Analysis • 20 (12%) Ton reduction in designed chiller size. • Reduction in number of chilled beams. • Right sizing reduces reheat. Auburn University – CASIC Lab Aggressive gathering of equipment data Equipment testing and user interviews

Understand Building Performance Commission Major Systems • $1/sf with a payback that can be less than 1 year. • “Tuned” systems can also improve occupant comfort. • Protect assets by ensuring proper function and optimal performance. • Can be performed on entire existing portfolio and new construction. • Energy savings can exceed 15-20%, particularly for energy intensive laboratories.
Understand Building Performance Metering and Evaluation • Cost $25 - $40 per data point • Additional $4,000 - $5,000 for web hosted dashboard (for entire building). • Wireless current transmitters can be easily outfitted onto existing circuits to submeter labs. • Metering helps with retro-commissioning and budgeting.
Understand Building Performance Metering and Evaluation • WIRELESS CONTROLS • Wireless telemetry allows for more individual controls. • Personal feedback allows for occupant behavioral transformation resulting in better operations. • Integrates well with smart grid technologies.

Generate Energy On-site Solar Hot Water • Integrating solar hot water, supplemental to or instead of traditional heating, could significantly reduce the need to reheat. • We have used this on 6 projects – including one lab and two hospitals. • Pictured below – the evacuated tube collector at the Center for Interactive Research On Sustainability at UBC.
Generate Energy On-site Solar Photovoltaics (PVs) NY State Energy & Research Development Agency, TEC-SMART. Photovoltaic panel arrays + two wind turbines produce power, while a ground source heat pump provides heating. The net result is an approximately 40% reduction in energy consumption. We have used photovoltaic energy on over 15 projects to date
