  • 3. Five Easy Ways To Begin Saving Money, Energy, and Water Want to start now to save money and resources? Here are five quick steps that make a big impact. 1. Replace incandescent light bulbs with compact fluorescent light (CFL) bulbs or low- emitting diodes (LED), and add motion sensors on common space and exterior lighting, except where safety and security are an issue. ENERGY STAR® qualified CFLs use approximately 25 percent of the energy incandescent bulbs use and last up to 10 times as long.1 The wide variety of available sizes and shapes will fit almost any indoor or outdoor fixture. 2. Add demand controls to the hot water recirculation loop, insulate all exposed hot water piping, and turn down water heater/boiler thermostats to the minimum temperature required for accommodating hot water needs. 3. Upgrade laundry equipment, refrigerators, and dishwashers to ENERGY STAR® appliances and reduce energy usage and water consumption by 10 to 50 percent. 4. Repair leaks and install sink aerators, low-flow shower heads, and toilet tank flappers to reduce the amount of water used. 5. Repair and aim sprinklers to deliver water only to where it is needed, and add weather-based irrigation controls to limit overwatering when rain is expected. Resident behavior is an important part of the efficiency equation. ENERGY STAR® and your local utility companies (energy and water) can provide tips, resources, and incentives to pass along to residents, promoting energy and water conservation through behavioral change and savvy consumerism. Ask your local energy and water utilities for more information about their consumer education resources, and visit the ENERGY STAR® website. You can also encourage recycling through offering information on recycling centers and providing recycling bins. ENERGY STAR® lighting, 1 Green Asset Management Toolkit for Multifamily Housing 3

In addition, we’ve provided a detailed description of useful cost analysis methods in Section 3.10 (p. 25): Methods of Cost Analysis. Increased Comfort and Health for Residents and Employees Green asset management means healthier residents and staff. When the products and materials used in property upkeep are taken into consideration as a matter of procedure, it is easy to identify and give preference to those that are less polluting and healthier than conventional choices. Air quality is a major factor in a building’s overall environment health, and thus green management emphasizes a ventilation system that removes pollutants tracked in from outside, while bringing in ample fresh air. The same measures applied to a building’s envelope and space conditioning in order to maximize energy efficiency also act to improve resident comfort by maintaining consistent and appropriate indoor temperatures. This, in turn, reduces the number of calls from residents about heating and cooling complaints, and can be especially beneficial in senior and special needs housing where residents Hotel Essex, San Francisco, CA are more sensitive to temperature changes.

Important Phone Numbers: Our Central Park @ Stapleton community focuses on sustainability! What does this mean? A part of being sustainable means SAVING ENERGY!! Northeast Denver gave you a head start by Maintenance Hotline: installing many energy efficient measures. We also had energy raters estimate the amount 303-377-6363 your Gas (Therms) and Electricity (Kwh or Kilowatt Hours) usage before you moved in. We used this to determine how much energy you should be using over the past 10 months. The good news? Many of you have “beat” the estimates and are using less energy than predicted!! Continental Divide: The graphs below allow you to see how YOUR unit compares to the estimate. 303-393-7368 Blue = Estimated Usage and Purple = How much you have used and other identical units.

  • 91. SEcTIon 8: appEndIx Appendix C: The Central Park Energy Flyover Continued Page 2 THE CENTRAL PARK ENERGY FLYOVER Two Ways to Save Money on Winter Heating Bills! Use a Programmable Thermostat: • Simply setting your house's temperature lower while you are away from home or at night will save a great amount of money. • A programmable thermostat allows you to do this without having to worry about it each day • Don’t set or program the thermostat higher than you actually want it. It will not heat your house any faster • If you go out of town, set your thermostat to a low temperature, yet high enough to keep pipes from freezing • If you need any help programming your thermostat, please call Peter Rusin at 303-399-9337. Use Cold Water when Washing Clothes: • Use the cold water setting as much as possible • Use hot water only for very dirty loads • Always use cold water for the rinse cycle • Run the washer with a full load How Much Water Have You Used? Your Unit 1 You have used a total of 57,773 gallons of water since January or 39 gallons per square foot of your living area. Some of your neighbors have been able to use a little less. Tip: Turning off the water while washing your hands or brushing your teeth is a small step you can take to reduce your water consumption. Cold Air Coming in Above the Kitchen Stove? In November, Northeast Denver Housing Center and Frontier Mechanical went through each unit to investigate cold draft issues in each unit. One common problem has been the cold air coming into the unit above the stove. We have found a solution. The parts are on back order, but we will be installing them as soon as they arrive. This improvement will help to keep your unit more comfortable and lower your energy bill. If you have any questions on cold air entering the unit, please call Peter Rusin at 303-399-9337. For all other maintenance issues please call Continental Divide. Green Asset Management Toolkit for Multifamily Housing 91
