Status quo and potential savings Energy costs Private households are increasingly looking for ways to save energy. Reasons include: – – – Energy costs represent a fairly large portion of household spending. Rising energy prices: Between 2000 and 2006, the price for heating oil has gone up by 50% (source: Swiss Federal Office of Energy, SFOE). Energy consumption is a key issue in the overall discussion on the environment.
Information on Synco controllers Our response to energy efficiency The Synco controllers from Siemens represent an unrivaled response to energy efficiency in buildings: – – Energy performance information Standard applications of the Synco controller range are classified fully under European standard EN 15232 ("Energy performance of buildings – Impact of building automation, controls, and building management). eu.
Guide – From energy consumer to energy user Energy-conscious behavior starts with selecting the right product (Synco controllers). Your Synco controller reliably and accurately ensures optimum comfort at minimum consumption. Operator units (room units, thermostat valves) and building operations allow you to further decrease energy consumption (see measures below).
Recommended settings for room unit and thermostat valves The following operator units are available for users: • • Room units (e.g. QAW740) Thermostat valves Typical action on the room unit: • Adapt room setpoint (absolute or relative). Command to controller: Control room temperature to adjusted setpoint. During the day, heat to max. 21 °C. Each additional degree raises your heating costs by 6%.
Correct placement of radiators and thermostats – – – Do not hang curtains or place furniture or other items directly in front of radiators. This prevents heat emission and impairs the thermostat valve's proper functioning (a). Avoid air flow obstructions (b). Make sure the thermostat valve is not exposed to direct solar radiation or cold air/drafts (c). Remove air from heating circuits Air may not collect in heating circuits. Air impairs heat emission of radiators.
Properly air out buildings (without ventilation system) Air out briefly and efficiently Condensation often is caused by ever increasing modern building shells as well as inappropriate airing out by occupants. Targeted, periodic airing out of living areas removes humid air and ensures required air exchange. Air out briefly, but completely open the windows. Recommended: Air out three times a day by opening all windows, for five to ten minutes each.
General tips Energy accounting Record and compare consumption – – Energy performance information Gain an overview of energy consumption data of your building (oil, gas, electrical consumption). Use heating cost bills and consumption data from previous periods. Your consumption data recording allows you to determine changes to previous billing periods or deviations between same-type/same-usage buildings (energy performance numbers).
