Heating, domestic hot water

BINE Projektinfo 09/2016: Sonnenhäuser energetisch und ökonomisch bewertet

Sonnenhäuser weisen einen Primärenergiebedarf von maximal 15 kWh/m²a für Heizung und Hilfsenergie. In den gut gedämmten Gebäuden deckt eine Solaranlage typischerweise zwischen 60 und 70 % des Wärmebedarfs. Der Rest wird meist über eine Biomasseheizung abgedeckt. Der geringe Primärenergiebedarf ist bei den Sonnenhäusers (auch SolarAktiv-Häuser genannt) mit Mehrkosten für die Gebäudehülle und Anlagentechnik verbunden. Ein neue Tool, das am Fraunhofer-Institut für Solare Energiesysteme (ISE) entwickelt wurde ermöglich nun die Berechnung der erforderlichen Mehrkosten.

UK Government starts "central heating for cities" scheme to reduce energy bills

The UK government has announced that ₤320 million will be invested over the next 5 years in schemes to support (local) district heat networks in cities. Heat networks are already used widely across Scandinavian cities to ensure space heating and hot water in buildings. The heat can be generated from various sources including large heat pumps, combined heat and power plants and deep geothermal plants but also from waste heat of factories and offices. The government sees a potential to reduce the heating costs by more than 30% for some households.


Germany starts new promotion programmes for the optimisation of heating systems and heating with fuel cells

On August 1, 2016 the Federal German Ministry for Economic Affairs and Energy launched two new promotion programmes concerning high efficient heat pumps, hydraulic calibration of heat distribution systems and the use of fuel cells for heating buildings. The optimisation of existing heating systems shall lead to quick and cost efficient energy and CO2 savings. It is expected that until 2020 up to 2 million heat pumps per year can be exchanged and 200000 hydraulic calibrations will be realised, thus saving about 1.8 million tons of CO2 emissions.

Deutschland startet neue Förderprogramme zur Heizungsoptimierung und für Brennstoffzellen-Heizungen

Am 1. August 2016 hat das Bundesministerium für Wirtschaft und Energie zwei neue Förderprogramme für die Energiewende im Heizungskeller gestartet: Das Förderprogramm zur Heizungsoptimierung durch hocheffiziente Heizungspumpen und hydraulischen Abgleich und die Förderung von Brennstoffzellen-Heizungen. Durch die Optimierung der Bestandsheizungen sollen schnell und kostengünstig Energie- und CO2-Einsparungen erzielt werden. Es sollen bis 2020 jährlich bis zu 2 Millionen Pumpen ausgetauscht und 200.000 hydraulische Abgleiche durchgeführt werden.

CHESS SETUP project kickoff: on the way to a building´s energy self-sufficiency

CHESS SETUP, a European project seeking buildings’ energy self-sufficiency


Low temperature thermal demand (Domestic Hot Water and heating) is worth 50% of the apartment buildings’ needs. A new European project looks for the most efficient solution to cover up this demand with solar energy, even during the months with the lowest level of solar radiation.

2017 ASHRAE Modeling Conference

The 2017 ASHRAE Building Performance Analysis Conference will take place from 27 to 29 September 2017, in Atlanta, Georgia, U.S.A. The conference, formerly known as the ASHRAE Energy Modeling Conference, has a broadened scope that encompasses all uses and aspects of modelLing, as well as the professionals responsible for that work throughout a building’s lifecycle.


The conference programme will consist of keynote speakers, invited speakers, a call for presenters and the ASHRAE LowDown Showdown.


European Commission requests BULGARIA to comply with EU provisions reducing the energy consumption of buildings


On 22 July 2016, the European Commission released a fact sheet containing its key decisions of the July infringement package. In this context, the EC has sent a reasoned opinion to Bulgaria to request the correct transposition of all the requirements of the Energy Performance of Buildings Directive (Directive 2010/31/EU) into national law.


Building Simulation (BS2017) 2017

Now accepting abstracts for peer-reviewed papers, due August 10th, 2016 with papers due November 30, 2016Abstracts will be judged primarily based on scientific soundness of the applied methods and the degree to which the contribution advances the state of the art.  Authors of accepted abstracts may submit 4 - 10 page manuscripts that will be double-blind reviewed.  Papers that are accepted and presented will be published in the citable conference proceedings. Non-paper oral presentations will be solicited later in 2016 -- that format may be appropriate fo
