2012 – The Compelling Economics of Greening Commercial Real Estate
• Generally perform 20%-30% better• Many trophy tenants – Corporate, State & Federal
are requiring LEED• When comparing Building A (LEED Certified) to
Building B (Brown Building), if buildings are similar, the Sustainable Building should win in 8 out of every 10 deals
• Economic Benefits – what if the studies are true?
GREEN BUILDINGS BECOME THE TIE BREAKER
www.ersgreen.com
Sustainability Made Easy
• Water – Though water is still relatively inexpensive for now there still are easy ways to save with a payback. Assume a cost of $5 - $8 per 1,000 gallons.
• Energy – The Holy Grail of Sustainability – The cheapest form of energy is one not used.
• Waste – Surprised at the low percentage of recycling rates across the Country.
• Indoor Air Quality – Healthy buildings increase productivity
FOCUS ON WATER, ENERGY, WASTE & IMPROVING INDOOR AIR QUALITY
START WITH THE LOW HANGING FRUIT
www.ersgreen.com
Water Savings - Restrooms
• Start with Aerators on Faucets - $2 - $5 each – Change out to .5 gpm aerators – Saves 331,000 gallons annually
• Urinals – Test .5 gpf flush valves – will work in most urinals without having to replace entire unit. Assume $100 each. Saves 195,000 gallons annually.
• Water Closets – Usually a Capital Expense – Recommend changing entire unit and not just flush valve to 1.28 gpf unit. New Technology helps these low flush units perform. Saves 1,154,400 gallons annually.
• Save up to $13,000 annually
SAMPLE BUILDING – 250,000 S.F. – 1,000 OCCUPANTS – 30 RESTROOMS – 3.5 GPF W/C - 1.0 GPF URINAL - 2.2 GPM SINKS
www.ersgreen.com
Water Savings - Landscape
• Have Landscape Contractor Provide Proposal on What It takes to Save 50% in Water and Provide Payback.
• Replace Sprinkler Heads – Use high efficiency heads - $5 each and will save 30% in water use.
• Use drip lines when applicable and rain sensors – Rain Sensors - $25 each.
• Satellite Irrigation Controls – Capital Expense – System controlled by Weather Satellite. Assume $10,000. Saves 40% - 50% on irrigated water.
SAMPLE BUILDING – 250,000 S.F. – 1,000 OCCUPANTS – SUBURBAN BUILDING WITH TURF
www.ersgreen.com
Water Savings – Cooling Tower
• Cooling Tower is the Largest Use of Water in a building.
• Install Controls on Cooling Tower - $1,000
• Meter the Blow Down/Evaporation – You pay sewer charges on all water that comes in through your domestic line. Show amount of water that did not go into sewer. Sewer Charge Rebate payback is weeks or months.
• Can we reduce water cycles per day in cooling tower without effecting performance.
BUILDING MUST HAVE COOLING TOWER

Energy Savings
• Portfolio Manager helps you track and assess energy and water consumption within individual buildings as well as across your entire building portfolio
• Enter energy consumption and cost data into your Portfolio Manager account to benchmark building energy performance, assess energy management goals over time, and identify strategic opportunities for savings and recognition opportunities
• For many facilities, you can rate their energy performance on a scale of 1–100 relative to similar buildings nationwide. A score of 50 would be an average building. Energy Star normalizes for weather, occupancy and building operation to compare with other buildings.
BENCHMARKING IN PORTFOLIO MANAGER FOR ENERGY STAR

Energy Savings
• ASHRAE Level II or Re-Commissioning – Huge opportunity to find low cost/no cost energy savings. Paybacks are normally less than 2 years but I find that they are less than 1 year.
• Savings are from 5% to 20% on energy.• Audit develops an understanding of the system
operation, identifies measure to optimize performance and develop a plan to optimize performance.
• Buildings I have performed Energy Audit for LEED Points are averaging 108% ROI on all LEED costs with a 1 year Payback.
ENERGY AUDIT
www.ersgreen.com
Energy Savings – Low Cost/No Cost
• Change 32 watt T8 bulbs to 28 watt – Eye can’t perceive a change in light. 12.5% savings on lighting. Also try 25 watt for additional savings.
• Delamp – If you have 3 lamp fixtures – remove center lamp. 33% savings.
• Stairwells – Burning 24/7 – Motion Sensors – Check with Local Authority First – Delamp – Reduce the amount of bulbs.
• Building Start Up – Perform Trials – Can we start up system 30 – 45 minutes later and still bring up to speed before tenants arrive.
YOU DON’T HAVE TO HIT A HOMERUN – SINGLES ADD UP TO HUGE ENERGY SAVINGS
www.ersgreen.com
Energy Savings – Low Cost/No Cost
• Building Shut Down – Can we shut down system 30 minutes to an hour early keeping fans running and let building load carry you through the rest of the day.
• Thermostats – As long as fans are running people can’t decipher a couple degrees in temperature.
• Visit Building After Hours – Twice a year property/facility managers should show up at building after janitorial has gone home and just look and listen to see what is on and what is running.
• Install Occupancy Sensors – Most old tenant improvements don’t have. Look at passing through as operating expense savings.

Waste
• Perform Waste Audit (Dumpster Diving) – Suggest hiring company to perform. Assume $2,000. Great tool that shows what is being sent to landfill that could have been recycled.
• Recycling Program - Put together program and communicate to tenants. Contest between floors?
• Recycling Cans – Make them convenient throughout tenant space. If you have paper recycling cans, no need to place liner in it.
• Recycling Rebates – Are you getting paid from waste hauler for recycling. They are!
• Compost Programs – Normally need refrigerated bin – maybe worms? Is green waste being recycled?
WHAT ARE WE THROWING INTO LANDFILL
www.ersgreen.com
Indoor Air Quality
• Cleaning Chemicals - Make sure Janitorial company is using Green Seal GS-37 cleaning chemicals on most products.
• Perform monthly janitorial walk throughs – Look for tenants bringing chemicals from home or other issues that could cause problems.
• Pest Control – What poison is pest company putting down on your property monthly. You would be surprised. Check with them about healthier alternatives – they do work.
• Walk Off Mats – 250,000 s.f. Building – mats will collect 500 lbs. of dirt per year.

Proposed Changes for LEED 2012 Now V.4
Sustainable Sites• No major changes except they pulled Alternative
Transportation into its own category.
Water Efficiency• V.3 – 1993 buildings and older 160% of baseline – V.4 –
1995 or older 150% of baseline• Lose a point for water metering plus an easy innovation
credit. Must now have 3 sources metered.• Cooling Tower credit has changed – V.3 just needed a plan –
V.4 chemical company will need to do an analysis.
BALLOTED JUNE 1 – 30, 2012 – CHANGED TO JUNE 2013
3 YEARS TO STAY IN 2009 VERSION
www.ersgreen.com
Proposed Changes for LEED V.4
Energy and Atmosphere• Prerequisite is 75 in Energy Star – V.3 was 69• Don’t receive a point until 76 – V.3 a 76 was worth 5 points –
2012 – 20 points for 95 in ES as opposed to 18 in V.3• Emission Reduction no cost point has been taken away.• Demand Response is new and worth 3 points
Materials and Resources• Waste Audit is now a prerequisite instead of a point.• New Prerequisite for Facility Alterations• E Waste Recycling no cost point has been taken away
BALLOTED JUNE 1 – 30, 2013
www.ersgreen.com
Proposed Changes for LEED V.4
Indoor Environmental Quality• Not a ton of changes in this section• Interior lighting credit has changed – No longer receive a
point for cubicles having a task light. V.4 – Must have 3 different light levels throughout.
Certified 40 – 49, Silver 50 – 59, Gold 60 – 79, Platinum 80 up
