What are the Society’s Conservation Goals:
• GOAL #1: 20% Portfolio Energy Reduction by 2020
• GOAL #2: 20% Portfolio Water Reduction by 2020
• Why is Energy/Water Conservation so Important?

Keep housing affordable
Reduce operating costs

20% by 2020: HOW DO WE DO IT?
Achieving a 20% reduction in utility usage is no easy task –
and requires a five-pronged approach.

Data: Track Performance
Standards: Replace Equipment
Operations: Best Practices
Maintenance: Maintain Efficiency
Retrofits: Overhaul Systems
Data: Utility Benchmarking
We can’t achieve what we can’t measure
• Where are we starting from?
•
•
What is the ‘baseline’ utility usage for each
property
How do we compare with similar properties?
• Where are we going?
•
How much do we need to save to reach our
goal?
Data: Utility Benchmarking
• Utility Benchmarking: the process
of collecting and accounting for
utility usage at a property and
comparing its usage with other,
similar properties.

Standards: Equipment Replacement
• Who decides what equipment model
get installed on site?
• Do you know a replacement unit is
“efficient”?
• Often these questions are answered by
vendors. Not anymore.
Energy Replacement Standards
• Reference guide for all property managers
currently in development.
•
•
•
•
•
All appliances must be ENERGY STAR rated
HVAC – efficiency metrics
Domestic Hot Water – efficiency metrics
Lighting – Replacement guide for LEDs
Plumbing – Recommended fixture/toilet flow rates
(GPM/GPF)
• Work Currently in Progress. Stay Tuned for
Rollout.
Operations: Best Practices
• Operational decisions can significantly
affect utility usage.
•
•
•
Thermostat Setpoints & Schedules
Hot Water Setpoints
Heating System Schedules
• How do you decide what these values
should be?
• Multiple Sources, which often differ
•
•
Local regulatory agencies
Vendors
Operations: Best Practices
• To help drive energy savings – a
standardized set of recommended
setpoints will be issued later this year.

Recommended HVAC Setpoints
HVAC Schedules
Hot Water Temperature Guidelines
Maintenance: Maintain Efficiency
• How do you ensure equipment efficiencies
do not degrade?
• Answer: Preventative Maintenance (PM)
• Installing efficient equipment is not enough – it must
be maintained properly.
• Proper maintenance practices will keep equipment
operating efficiently.
•
PM Standardization project will incorporate new
inspections focused on eliminating energy and
water waste.

Retrofits: Overhaul Systems
• Retrofits are a last resort, but will play a
part in reaching the 20% savings goals.
• Is your property a good candidate?
What to look for:
• Older Lighting – especially 24/7 Lighting
• Incandescent; T12 Fluorescent
•
•
•
•
High Usage Toilets – above 1.6 GPF
Over-Heating – Is it too hot in the winter?
Pipe Insulation – are hot water pipes insulated?
Roof Insulation – is there any insulation?
Retrofits: Overhaul Systems
• Retrofits typically offer the biggest
potential for reducing energy or water
usage.
• However – they’re also the most
expsensive.
