Software and Tools
The design and optimisation of energy-efficient buildings – whether for new buildings, refurbishments or during building operation – requires suitable design methods, data and tools. Of course, architects, designers and building operators have considerable experience in using computer-aided planning tools. However, the challenges when designing particularly energy-efficient buildings are diverse: in addition to planning software currently available on the market, there are also specialist tools and innovative approaches for simulating buildings and systems, which have been developed and tested as part of research projects.
Here we present a range of planning tools that have been developed as part of the EnOB research.
The energy balancing of buildings according to DIN V 18599 has been frequently criticised because of its complexity and time-consuming application. Calls to simplify the process came soon after the pre-standard series was first published. As part of a research project, the Excel-based EnerCalC tool has now been developed that is particularly suited for characterising buildings in terms of their energy use during the preliminary design phases.

Calculating the lifecycle costs for buildings or system technology can help to achieve an economic balance between the initial construction and subsequent usage costs. The method is particularly interesting for the early design phases, where many decisions have a significant impact on the energy consumption and further utilisation costs. In this research project, software was developed as a planning and decision-making aid for architects, specialist designers and energy consultants.

This research project seeks to develop a tool for assessing conventional and innovative cooling technologies. The tool is intended to facilitate the assessment of systems for solar cooling, combined heating, cooling and power as well as active and passive cooling using reversible heat pumps and to compare the technologies with conventional cooling systems in terms of their energy efficiency and economic viability.

This research project seeks to develop and test tools and methods for determining the energy efficiency of cooling systems in ongoing operation. Specialised algorithms are to be developed for recording and analysing operational system data and implemented in a software package for energy efficiency analysis as a prototype. Structure and condition modelling for cooling systems is to form the basis for automation of prognosis and diagnostics processes.

Cooling systems used in office and production buildings often require a needlessly high level of energy. So far, suitable tools to assess easily if a refrigerating system is running efficiently and to identify optimisation and saving potential in ongoing operation do not exist. This research project developed a software-supported methodology for the operational analysis and system optimisation of cooling systems that can soon be used in the form of an Excel tool.

Energy management systems are designed to reduce the energy consumption in buildings. The enerMAT design environment is already implementing such a system during the planning phase. This enables informed decisions about the investment and operating costs, energy savings and comfort to be made at an early stage. The use of simulation-based verification and optimisation methods dramatically simplifies the complex design process for trades-spanning energy management.

The share of renewable energies in the German electricity generation will continue to increase. Fluctuations in the availability of renewable electricity from wind and photovoltaic plants mean that not only the quantity, but also the time of the electricity consumption will play an increasingly important role in the future. Buildings with electricity-based technologies for heating and cooling (e.g. heat pumps, compression chillers, CHP plants) will contribute to relieving the electricity system and reducing the demand for electrical storages and energy conversion processes by shifting the electricity consumption for heating and cooling temporarily, using technical storages and the mass of the building to store the energy as heat or cold.

ModQS is a newly developed quality assurance system for the operation of buildings. Building operation is supposed to become more efficient with the support of a combination of model-based methods for fault detection, fault diagnosis and system optimisation. The new system has been used in several non-residential buildings to continuously monitor and optimise heating installations. The aim is to expend as little energy and operating costs as possible while achieving the highest possible level of occupant comfort.

The Internet-based working platform enables the design of system descriptions, automatic analyses of operating data and reporting functions for engineers, building owners and users. Thanks to innovative Web 2.0 technologies, the working platform can be used online by all project participants throughout the entire lifecycle. The Energy Navigator enables the operation of buildings to be systematically supported.
