Recommendations for the Effizienzhaus Plus Standard - Expert survey and best practice examples

The Effizienzhaus Plus Standard can make an important contribution towards a climate-neutral building stock in Germany. Efficiency House Plus Buildings produce more energy from renewable sources than they need for their operation. A planning guide developed within the project provides recommendations for the successful implementation of the Effizienzhaus Plus Standard in residential buildings.

Market design for the public construction sector – feasibility study

The goal of market design is to improve the performance of existing markets by actively shaping their rules. To this end, market designers examine the peculiarities of the respective market and identify the mechanisms of action prevailing there. In order to find a market mechanism that best achieves the market operator's goals, market designers use theoretical, experimental and empirical methods.

Energetic monitoring of two "Effizienzhäuser Plus im Altbau"

As part of the competition "Effizienzhaus Plus im Altbau" ("Efficiency House Plus in old buildings"), which was awarded in 2012, two residential areas dating back to 1938 were renovated in Neu-Ulm. The two different concepts of the realized model projects should exemplarily show how a sustainable further development of the residential building stock to the Effizienzhaus Plus for the wide application can be implemented in terms of building.

User behaviour and its influence on the energy consumption

This research project collects present knowledge about the energy consumption of residential buildings, about the effects of energy upgrades and about the influence of users. From this suggestions for supplementing the energy performance certificate are derived, aiming at a realistic assessment of energy savings by refurbishment measures and at an indication of the positive effects on the thermal comfort.

Possible options for considering grey energy in regulatory law or in the field of funding

The Energy Saving Regulation and energy efficiency debates focus almost exclusively on the required operating energy during the use phase of the buildings. The grey energy, which describes the material-related energy expenditure for a defined period of time, is usually neglected in the planning of buildings. The study examined how grey energy can be taken into account in a holistic balancing of building energy in the entire life cycle.

Importance of the patent system for the German construction value chain

Due to its contribution to the total gross value added, the construction industry is often seen as a key sector of the German economy. The importance of the sector is even higher when taking into account the entire construction value chain. In Europe, the German construction value chain has a leading position in terms of innovation measured by building-relevant patents. Still, there is a considerable need for research on the relationship between patenting and technological innovation in the construction value chain. Based on a patent analysis, interviews with experts in the construction sector and a company survey, this project aimed to close existing information gaps.

Investigation and development of fundamentals for updating the procedure "EnEV easy" for residential buildings

The current version of the Energy Saving Ordinance (EnEV) requires a calculation of the energy demand of newly constructed residential buildings to determine their efficiency standard. Since the determination of the demand is very complex, time-consuming and costly, a simplified procedure "EnEV easy" was developed and published in 2016. In this research project, the update of the existing procedure has been prepared, along with its inclusion in a draft of a new Building Energy Law (GEG).

Influences of heavy rainfall on the building infrastructure

Numerous heavy rainfall events have in the past led not only to personal injury but also to severe damage to the building infrastructure. In addition to pure property protection, measures are developed to protect the building infrastructure against the effects of heavy rainfall according to the model of the so-called "sponge city", while at the same time promoting a sustainable use of precipitation water. This also has other environmental potentials.
