Agenda

• Big Data and what to do with it • What is benchmarking? • Analyzing results, taking action



Buzz word bingo

Big Data – 1000s of props, millions of invoices Analytics –

slice and dice Big Data into bite sized chunks Benchmarking –

what is it? can it help me?



What is benchmarking?

A yardstick - How do you measure up? 1. Self over time

Trending/YOY

2. Other buildings within portfolio Internal Benchmarking

3. Outside "peers“ External Benchmarking



"Apples to Apples"

Need two things: • Common unit of

measure • Filter by big impacts



Common unit of measure

• Need this to calculate the comparison • Usage (kwh, therms, gal)

– per square foot or per unit or per person

• Dollars – per square foot – per unit



Filter by big usage impacts

• Geographic area (metro or climate zone) – weather may have big impact

• Use type (residential/mixed/office/etc) – occupant behavior may have big impact

• Physical characteristics – high rise vs garden – common area only vs whole building

beware too many filters!

External benchmarking: How do you compare?

Benchmark area

Benchmark properties

Your properties



Internal benchmarking

WaterElectricityNatural Gas

• Water/sewer 50% • Electricity 28% • Natural gas 18%

(less in South)

+ Waste & recycling Total spend distribution based on NAA 2013 study

Peel back the layers on each resource



Internal benchmarking

• Which communities are the costing the most money?

• Which are wasting the most resources?

Your Water & Energy Hogs

Customized benchmarking reports



Continue to peel back the layers

• For each commodity, what components are driving my utility costs? – rate – consumption

• weather • physical asset • behavior

The tough questions

• Once I know which commodities are costing the most, which systems or equipment are wasting the most utilities?

• What CapEx projects should I prioritize?

Pro-grammable

Thermostats

Toilets

Leaks Lighting

Water Heater Wraps

Shower Heads

Irrigation Controls



Where should I start on water?

Many Customers Find: • Irrigation can account for 30% to 60%

of your total water usage – Smart Controllers and efficient spray

heads can cut irrigation water usage by up to 30%

• Savings of +$100/unit/year – Low flow aerators and showerheads are

cheap and can cut usage up to 30% – Toilet retrofits can cut water usage up

to 50% • Leaky toilets and faucets can

waste up to 200 gal/day (check flappers!)

Where should I start on energy?

Many Customers Find: • Some projects have good ROI and low

overall cost impact – Lighting retrofits – Variable speed pool motors

• Gas savings of up to $40/unit/yr – Low flow showers can cut hot water

heating costs – HW Boiler demand controllers can have

payback < 1 year • HVAC uses the most energy, but replace

near EOL due to cost

What do I do now?

• Information overload – your head is spinning • Start with whatever you HAVE now… there is

no perfect report • Ask questions about your data, look for red

flags (spikes, anomalies) – Good numbers = STOP – Bad numbers = don’t stop until you find the

cause • Work towards collecting more detailed data

going forward



Start at the top

• Lay out what you know • Put them in order – what are the top 3? 10? 5%? • Now go look at the first one (the worst one!)



Outliers



Use your G/L



Ask a lot of questions

• Manager, RPM, Maintenance • Previous Reports, Projects • How old? What kind? How many? • Google Earth



Call in the professionals

• Lighting proposal • Irrigation proposal • Water fixtures proposal • Leak detection • Level II ASHRAE audit?



Do something

• Do anything • Do small things 100x • Do one big thing ….Watch what happens

Big irrigation project

New shower heads

Turn the lights off



Results multiply

Year over year cost savings Compare your utility costs to benchmarks Compare to NAA data

Now, go to work on the next one…
