We ensure compliance with the statutory requirements of the market heating and operating costs and take care of any special requirements, such as billing according to user groups, verifying labour costs and providing tax statements. The result is an easily understandable overall bill for you and individual bills for your tenants. You can send us the relevant billing data easily and conveniently in three different ways - you have the choice.

� A clearly structured overall bill showing all of the operating costs per tenant

� Legally compliant, easily understandable individual bills for your tenants

� Greater billing accuracy due to comprehensive plausibility checks

� Various billing models, tailored to your individual requirements

� Expert assistance if any queries regarding billing should arise

Special billing forms are quickly and easily accommodated

Billing in accordance with Local Country Tax RegulationsIf you or your tenants/owners wish to include household-related services, employment relationships or handicraft services in the income tax return, these must be shown separately in the operating costs bill.

We identify the proportion of labour costs for you, so that we can allocate these to your tenants or property owners according to the agreed billing and allocation formulae.

Considering heat emission from pipesIf the proportion of unrecorded heat emission from pipes is high, it may be necessary to correct the allocated costs accordingly. This means that some of the users profit from the heat that radiates from the pipes. The costs of this heat, however, are also borne by the remaining users, who thus pay a higher price per metered consumption unit. Using the market agreed balancing procedures on heat emission from pipes, we ensure that the generated heat is allocated more fairly throughout the building.

Billing for renewable energy sourcesThe requirements for measurement equipment have become much more complex with the introduction of combined heat and power plants, solar plants and geothermal power plants. We provide reliable consumption-dependent billing with the help of state-of-the-art measurement equipment. On request, we can plan and implement the installation of the necessary equipment in cooperation with your local installation company. This means that you can place the fitting-out, meter-reading and billing processes securely in the professional hands of specialists.

User groupsIn some buildings, the heat consumption is measured using various different measurements or recording devices. This could be the case, for example, if some of the apartments have under-floor heating, while others have conventional radiators. In such cases data can be separately recorded for each so-called user group. Creating separate user groups for different types of building or building use, or for other practical reasons, may also be prudent. Based on your information regarding the property, we define these user groups for the purpose of consumption- dependent billing.

Billing for commercial propertiesWe provide the same expert and comprehensive metering and billing services for commercial properties as we provide for the residential sector.

Contact us at an early stage to discuss the billing requirements for your property and we will ensure that your billing is easy to understand and legally compliant.

All details can be found in the ista brochures entitled: “ista special - Consideration of heat emission from pipes in heating cost bills” (Art. No. 83013) “Consumption-dependent billing

for renewable energy sources” (Art. no. 84019)

Overall and individual billing –as easy as that

The overall bill for property managers and landlordsBilling for properties that are made up of many separate units can be complicated due to the various different parameters and calculation formulae involved. We make your work much easier and our billing model ensures that you have a clear understanding.

All of the costs can be seen at first glance, and all of the relevant calculation steps are easy to follow. A good overview provides the kind of reliability and transparency that no one should be without.

The individual bill for property owners and tenantsOur bills for heating and ancillary costs are economical, clearly presented and widely recognised within the sector to be among the most easily understandable of their kind. As a result, queries from owners or tenants tend not to arise in the first place. This keeps your input and expenditure to an absolute minimum. If any queries do remain unanswered, our staff are there to provide reliable information.

The first page of your overall bill presents all the important information clearly and simply.

Supplying energy and smart metering –Advantages for property managers and tenants

Energy supply, measurement services, smart metering and billing, all rolled into one: this is the new energy supply concept for the housing sector that we are putting into practice in cooperation with specific partners. In Germany, our subsidiary GENEK supplies the energy and meter operator services, we apply our expertise in the field of energy service provision and the installation of suitable, intelligent measurement equipment. This means: everything runs almost automatically!

The smart meter - brings benefits to all concernedThe most ingenious element of the new energy concept is the new smart meter. In comparison to conventional recording devices, these intelligent meters can save individual consumption values and transfer the collected data automatically to us. This simplifies and shortens the billing process considerably. In addition, the use of smart meters provide the basis for constant transparency with regard to consumption and costs.


� Real-time reading of consumption values on the reference date

� The date of electronic billing can be specified� Ancillary rental costs are reduced � Letting potential is improved

Benefits for your tenants:

� Financial benefits with regard to “warm rent” (total rent including heating costs) and the tenant‘s own electricity consumption

� Legally compliant billing of the tenant‘s individual heating and electricity consumption

� Expert installation of metering equipment, carried out by specially trained personnel

� Convenient reading of consumption data via radio remote

� Electronic bills produced using real-time data

Property comparison: an important aid for modernisation projectsThe property comparison feature enables you to carry out a detailed assessment of your property. You will be able to immediately identify areas that require modernisation or renovation and carry out these works using a targeted and systematic approach.

Comparison of usage units: identify any deviations from reference values quickly and clearly The comparison of usage units involves taking the latest energy consumption and cost figures for heating and hot water and comparing the figures from each usage unit within the property with the average value and with an ista reference value. This enables quick and easy identification of units that have widely deviating consumption and cost figures. Comparisons can be made not only within a particular property but also between different properties.

ista Energy Data Management premium – data evaluation the whole year through

Traffic light matrix: quick comparison between the consumption and cost figures of individual usage units.The traffic light matrix gives a quick overview of individual usage units whose figures lie above or below the average consumption or cost values. This provides you with a good basis for purposeful advisory discussions with your tenants, aimed at actively reducing energy consumption and costs in the future.

Property comparison: a detailed overview of the last few billing periodsThe time period comparison shows the development of the energy consumption and cost figures for heating and hot water over the last few billing periods for buildings as a whole. Up to five previous periods can be selected at the same time here. Using this yearly comparison as a basis, it is possible to assess the sustainability of the economic success of your modernisation and renovation measures.

ista stands for first-class service -this is endorsed by the company’s voluntary certification

Tenants’ portal: for more energy awarenessOne of the special features of the Energy Data Management premium service is the tenants’ portal. Here, your tenants can check their current consumption figures online whenever they like. In times of rising energy prices, users of sustainable energy data management services have the important advantage of being able to spot unusually high energy consumption figures and their associated potential energy savings easily and without delay.

E

26


With the ista app you have even greater flexibility, since you can even access the consumption values and costs of your properties when you are on the move.

Vacancy management:identify unnecessary consumption quickly and easily With the vacancy management facility, consumption in vacant usage units can be identified in real time. This allows you to identify and avoid unnecessary costs that would otherwise remain undetected until the annual operating costs are billed. The traffic light matrix for vacancies, accessible via the ista web portal, gives a clear overview of consumption values for heating, hot water and cold water in the vacant units within a property: Green shows normal consumption, yellow shows the average consumption and red shows above average consumption.

Advance payments management: act early to avoid back paymentsThe advance payments management facility enables you and your tenants to actively avoid large back payments for operating costs. The ancillary costs accrued to date are compared at both property and user level. The costs that will accumulate up to the end of the billing period can then be forecast on this basis. This will allow you to check at an early stage whether the prepayments made by the users will cover the accumulated ancillary costs at the end of the billing period.

Energy management | Energy pass

In Germany: Energy pass – fulfilling the statutory obligation

The consumption-oriented energy passThis states the actual energy consumption per square metre. The corresponding data is determined on the basis of the heating cost bills of the last three years. The results are influenced by the user behaviour of the tenants. We issue the consumption-oriented energy pass.

The demand-oriented energy passIn this case, building envelopes, construction materials and the heating system are analysed. The result is an objective picture of a building‘s energy characteristics and is independent of the behaviour of individual consumers.

All types of energy pass, from just one sourceWe offer consumption-oriented energy passes for both residential and non-residential buildings – regardless of whether you are already an ista customer or not. We also supply demand-oriented energy passes. We prepare the energy pass in collaboration with experienced energy consultants. Contact us!

In Germany: Smoke alarms – safety for you and your tenants

The installation and maintenance of smoke alarms is already firmly anchored in the building regulations of many German states. Considering the many tragic smoke-related accidents in residential buildings that we hear about time and time again, these mandatory requirements are a necessary development. Most victims of fires are not killed by the flames but by the poisonous smoke that takes them by surprise while they are sleeping. We protect your tenants and your property by installing modern smoke alarms in your apartments and ensuring that they are properly maintained.

Tenant safety | Drinking water analysis

In Germany: Drinking water analysis - clean water means preventive protection for tenantsOur drinking water is subject to strict checks in accordance with the German Drinking Water Ordinance. It is still possible for health hazards to lurk in the drinking water, however. Legionella, for example, can contaminate water pipe networks and hot water tanks. To reduce the danger of an outbreak of legionnaires‘ disease, the October 2012 edition of the German Drinking Water Ordinance (Trinkwasserverordnung) introduced more stringent regulations. We can help you to fulfil these new requirements.

Is your property affected by the amendments to the Drinking Water Ordinance?

Testing is a requirement for residential properties that meet all of the following criteria:

The property has more than two apartments

At least one apartment is rented out

The property has showers or shower-heads that create a spray mist

There is a central drinking water heating system

The volume of the hot water tank is greater than 400 litres

or

the volume of water in the pipe between the hot water tank and the outlet is greater than 3 litres
