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!

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?

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!)
