The U.S. Department of Energy website: http://www.energy.gov/yourhome.htm WATER CONSERVING LANDSCAPE Landscape Water Use Conservation Methods: There are many methods to reduce the amount of water used in a landscape and still maintain the health, appearance and function of the landscape. The following area few examples: Conform to City of Newport Beach Water -Efficient Landscaping Ordinance or the California Department of Water Resources' model Water Efficient Landscape Ordinance. ➢ Use water -efficient landscape designs utilizing native and drought tolerant plants and minimize turf areas. ➢ Use mulch, soil amendments or other soil improvement methods to reduce water loss through evaporation or runoff and to improve water availability for plant use. ➢ Install efficient irrigation systems and follow a regular maintenance schedule. Adjust irrigation controllers as necessary to accommodate changes in seasons and plant needs. ➢ Schedule landscape irrigation during early or late hours. ➢ Stay current on new technologies, strategies or products that promote efficient water use. Irrigation System Design: Homeowners or a design professional can develop an efficient system design meeting homeowner expectations while also reducing waste and conserving natural resources. When planning landscaping and irrigation, the following ideas can help: ➢ Design irrigation systems to be consistent with hydrozones (areas of plants with similar water needs.) ➢ Minimize the usage of spray heads. ➢ Install a low consumption irrigation system such as drip or subsurface. ➢ Use graywater or recycled water when possible. ➢ Consider rainwater catchment and storage systems. ➢ Follow the manufacturer's installation instructions to ensure optimum system efficiency. Irrigation Controllers: ➢ There are several types of irrigation controllers that base the irrigation schedule on evapotranspiration data. ➢ Other irrigation controllers may use a combination of historical data and real-time data feeds from on -site temperature sensors, soil moisture sensors, sunlight intensity indicators or they may use data from weather stations. ➢ Weather and/or soil moisture- based controllers represent technological advances in irrigation that enable the proper amount of water required by the landscape plants or postpone irrigation during periods of rain. Utilizing these "smart" controllers is an improvement over irrigating by an arbitrary "run time" where the amount of water needed and the amount of water applied may not be effectively matched. PORTIONS OF THIS PROPERTY WILL REQUIRE ROUTINE MAINTENANCE FOR WHICH THERE MAY NOT BE A SPECIFIC MANUAL Grading: The grading around the building is sloped away from the structure, which is not only functional, but a building code requirement enforced during the final inspection. The yard drainage must not drain onto neighboring property or near the building foundation. It is important the owner or tenant maintain this grade or swale to protect the building from moisture. An inspection after any landscaping, construction or a storm is necessary so the swale or grade always directs the flow of water away from the foundation of the building and to storm sewer systems or other appropriate locations approved for the structure. Gutters: The gutter and downspouts will need periodic maintenance to ensure proper function. The required interval for this maintenance will vary by season; however, gutters and downspouts should be inspected for debris before the rainy season. When trees and other deciduous vegetation shed leaves that drop into the gutters, this will inhibit the flow of water and possibly clog downspouts. The leaves and/or debris must be removed in order for the system to work as designed. The downspouts should direct the storm water away from the foundation at least 5 feet to avoid damage to the structure. Always keep the area clear where the storm water flows out of the downspout. If a clear area is not possible, subsurface drains may need to be installed. Irrigation: Inspect the landscape irrigation systems weekly for leaking or broken heads. Frost -Protected Foundation Systems: When the building utilizes a Frost -Protected Shallow Foundation, as allowed by local conditions, the monthly mean temperature of the building must be maintained at a minimum of 640F (180C). Relative Humidity (RH): RH is the percent of moisture in the air compared to the maximum amount of moisture this air can hold at the same condition. Warm air will hold more moisture than cold air. The design of the HVAC system should include controlling the moisture levels appropriate to the climate. The addition of moisture (humidification) may be required in colder climates during the winter season and removed (dehumidification) during the summer months. Automatic, computer controlled humidifiers can control the humidity levels, providing enough moisture for a healthy comfortable dwelling and within the limits to prevent window and cold surface condensation. These levels are usually between 30 to 60 percent RH although certain health conditions may dictate benefits at either the higher or lower ranges. Hygrometer: The hygrometer will show RH. Although the RH will not be exactly the same throughout the structure, one hygrometer is usually sufficient. It should be placed where the humidity symptoms are most obvious (e.g., in the room that you are most concerned about.) Low Relative Humidity: Below 30 percent RH, people can be uncomfortable and can suffer from dry mucus membranes, which can lead to nosebleeds and infections. In general, low RH is only a problem during the winter months when the outside air contains very little moisture. It is this dry outside air entering through cracks and openings in the building shell that causes the inside air to become dry. The greater the amount of outside air that leaks into the building the dryer the indoor air becomes. By air -sealing and using energy -efficient construction, uncontrolled air leakage is greatly reduced, a more controlled indoor environment is created, and RH can be maintained at acceptable levels without the use of a humidifier. Humidifiers require maintenance to avoid becoming breeding grounds for biological contaminants. The effects of bacteria, viruses, fungi, respiratory infections, allergic rhinitis, asthma, and ozone production can be minimized by higher humidity levels. Studies have shown that wintertime operation at 68° Fat 70% RH provides the same level of occupant comfort as does 720 Fat 30% RH. Lower utility bills and a healthier environment are both benefits of controlled RH. High Relative Humidity: High RH can lead to occupant discomfort, annoyances, and possibly serious health issues as they relate to bacteria, viruses, fungi, mites (dust mites and mold), allergic rhinitis, asthma, and chemical interactions with mold, dust mites, and other biological pollutants. The air conditioning system and/or stand-alone dehumidifier are designed to remove moisture (latent load) and decrease the RH levels. Studies show that summertime operation at 78' Fat 30% RH provides the same level of occupant comfort as does 74° F at 70% RH. The lower humidity level will provide increased comfort, lower utility bills and lessen the risk of health issues associated with high humidity. Using exhaust fans in the bathrooms and kitchen can remove much of the moisture that builds up from everyday activities and help keep RH below 50%. Having a humidistat connected to an exhaust fan is required in bathrooms. This is an effective way to control RH in moisture prone areas. When using an adjustable humidistat, the setting should be adjusted according to the season: lower RH in the summer and higher RH in the winter. Another benefit to using kitchen and bathroom exhaust fans is removal of odors and pollutants. These fans can also be part of an active whole house ventilation system for the entire house and help to reduce humidity levels.
