Agenda

Making Climate Neutrality a Reality

• Actions to eliminate greenhouse gas emissions,

broaden academic research, and enhance educational

• pportunities and outreach efforts by the year 2050.
• Cornell’s Climate Action Plan (CAP) promotes the

education and research needed to generate solutions for the challenges of global warming —and will demonstrate these solutions in campus operations. Climate Action Plan

Climate Neutrality by 2035

• Broad vision for the campus.
• Lab ventilation constitutes about 50% of the $60

million energy costs per year.

• Cornell’s fume hood exhausts represent about

15% of Tompkins County’s carbon footprint.

• Ventilation is the largest user of energy in labs.

– One fume hood = 3 households annual energy usage. – Lowering your fume hood sash is both safer and conserves energy.

• Cold storage of samples is the second largest use
• f energy.

Climate Action Plan 1.Plan space to avoid new buildings 2.Reduce energy demand 3.Use renewable electricity and renewable heat 4.Offset business travel and commuting

Forecasting

• Provides the basis for setting budgets
• Weather based for heating and cooling
• Take into account:
• ECI projects and ECCT recommissioning
• Major building renovations/new construction
• Building maturation (important for newer

buildings)

August 2016

August 2016 12

• Forecast is developed for each meter

–100 chilled water, 150 steam, 300 electric –Steam and chilled water require weather regression

• Reviewed / Updated each budget year based on

performance.

• Track performance quarterly
• Building and Campus EUI is tracked and managed
• EUI reporting is part of online IPP metrics

Energy Conservation Initiative (ECI) Phase I and II

• Phase I
• 2000-2008 $10 Million project cost
• Energy savings target of $1M annually
• Phase II
• 2010-2015 $33 Million project cost
• Energy savings target of $4M-$5M annually

Endowed 2003 – 2017 (~5M GSF) CCF 2005 – 2017 (~4M GSF)

Maintenance (Continuous Cx) Project Study Design Maintenance (Continuous Cx)

Professional Schools 2011-2013 (~1M GSF)

Steps of ECI

Campus Life 2011-2015 (~3M GSF)

• Lighting – fixtures and occupancy control
• Updating of controls and control logic
• Complete Cx and Re-Cx of systems
• Humidification systems

Conservation Project Elements

Laboratory ventilation is responsible for approximately half of all energy use on campus ~ $30 million per year at billed rates – Focus on controls to reduce outside air use – Occupancy sensors to index room occupancy air flows, and lighting – Relax temperatures to reduce reheat Energy conservation in laboratories

• Work with EH&S to determine spaces that

can have their airflow reduced from 8/4 air exchanges per hour (ACH) to 6/3 ACH

• ccupied/unoccupied
• CFD analysis
• Pilot testing
• 25% Airflow reduction in laboratory spaces

represents a very large potential savings - $ millions/year

Energy conservation in laboratories

• Electrical savings to date
• Over 50 buildings retrofitted
• ~1400 kW reduction (peak)
• 5,000,000 kWh/ year
• 4.2 year simple ROI (2.1 year after

incentive)

Campaign Kickoff and Green Recruitment

It’s how we live and work at HUMAN ECOLOGY

– Higher level green team collaborative sessions – Soft launch entertainment event (earth day) – Open recruitment for anyone interested – Green team kickoff collaboration planning event – Quick win event like a “lights out” or “turn back the stat” to engage the entire population. – Selectively recruit those most active to lead departments and units as Green Ambassadors.

Green Office and Lab certification program

It’s how we live and work at HUMAN ECOLOGY Public recognition for staff and faculty engagement:

Personal lab and office assessments 180 people participated Human Ecology has more office and labs green certified than the rest of campus combined Awards were given for all certified labs and

• ffices based on level of certification.

Building Energy Dashboard Smackdown

Real time energy conservation competition using the building dashboards to track savings percentage under last years usage. Building %Reduction 2014 2015 LEED Beebe Hall 24% 37% None MVR West 33% 34% None MVR Main 29% 30% Gold HEB 5% 21% Platinum S/K Hall 9% 14% None

Total Saved 301,000 kwh in six weeks ***These changes currently remain in place so the savings has continued***

Common Collaborative Opportunities

It’s how we live and work at HUMAN ECOLOGY

Lighting and technology- Use custodial support to re-lamp with LED lights Use students to lead a “Lights out” campaign Use BMS for building occupancy schedules Building scheduling and common/ shared spaces Encourage the use of shared teaching labs Work with registrars to consolidate schedules Encourage the use of commons areas as the hub Understand the Programs needs for use of spaces Not all labs are heavy chemical labs Space programing for HVAC comfort Consolidate and share specialty equipment

Use Fun Facts to stay on target

It’s how we live and work at HUMAN ECOLOGY

These efforts have saved a combine 301,693 KWH

• ver a six week period of time within 650,000 sq ft
• f building spaces.

Multiplying those savings out for the year is equivalent to : Driving 176 trips around the world 83-garbage trucks of waste recycled instead of landfilled 271-family homes fully powered for a year Or 1838- 30’ tall balloons filled with CO2e
