The CECB® is the official cantonal energy certificate for buildings. It indicates the energy efficiency class of a property and gives advice on renovation needs. The CECB® Plus is the next step.
It is the product of your discussion with an expert CECB about your wishes and goals for energy renovation. After a thorough analysis, the expert CECB® draws up a detailed report, the CECB® Plus. Three packages of measures can be proposed. The analysis includes the building envelope, heating, hot water production and all other electrical appliances.
Here is a classic example: your oil heating system is reaching the end of its life and you are planning to replace it. With CECB® Plus you can compare three different heating systems or packages: a new oil heating system, a heating system with a pellet boiler and an air-to-air heat pump with façade insulation, for example.
The CECB® Plus serves as a decision-making tool, showing you the necessary investments, the available Subsidies and the future maintenance costs and savings for each of the proposed options. The CECB® Plus is therefore the ideal tool to approach the renovation of your house. The comparison of the renovation options provides you with a solid basis for your decision. The CECB® Plus can also be the starting point for a renovation according to the Minergie model.
With a CECB® Plus certificate, you can be sure that the renovation measures, especially the replacement of the heating system and the insulation of the building envelope, are perfectly coordinated. This is essential if you are carrying out the work in stages.
If you discuss the renovation measures to be carried out directly with the various specialist companies, they will certainly offer you the most effective solutions. However, their cost effectiveness may not be in your interest. The expert CECB® provides you with objective advice and pragmatic solutions.
The federal government, and sometimes even the cantons and municipalities, provide Subsidies for energy renovation. If you apply for Subsidies, a CECB® Plus will be required in many cases.
CECB® allows you to assess the energy performance of your home. This objective diagnosis allows you to classify your property according to its energy efficiency and to identify how to reduce your energy expenditure for heating, domestic hot water, lighting and other consumption items.
CECB® Plus allows you to improve the energy efficiency of your building through concrete and quantified measures. These scenarios determine the potential energy savings, the investment cost and the amount of Subsidies you can benefit from, taking into account your priorities.
Any energy renovation initially involves significant investments. The annual savings seem small compared to these in the short term. However, energy renovation pays off in the long run. Sooner or later you will have to consider major expenses anyway, such as replacing the heating system, renovating the facade, etc. In addition, the prices of fossil fuels will rise considerably in the next few years due to higher taxes and incentive taxes.
Energy renovation is also an important component of maintenance, and thus of maintaining value, and is therefore an asset when selling. It is also possible to deduct renovation costs from taxable income. Finally, the state provides support. CHF 450 million from the CO2 tax on fuels is being used to provide financial assistance to property owners to increase the energy efficiency of buildings. Detailed information can be found in the full report of CECB® Plus.
An ideal temperature for the production of domestic hot water, taking into account aspects such as hygiene, scale content, comfort and compliance with legal requirements, can be below 55°C. If the hot water temperature is insufficient at this setting, increase it gradually. This is to achieve the desired temperature at the tapping points. However, once a week, the temperature must be raised to 60°C for one hour to avoid any risk of legionella. If your installation does not allow you to program this recommended weekly temperature increase, set the temperature to at least 55°C in the boiler. The temperature at the tapping points (taps, showers, etc.) must always be 50°C. If this temperature is not reached, this may be due to a lack of insulation in the pipes.
