Heating, domestic hot water

Strategies for mitigating the risk of overheating in current and future climate scenarios

Designing domestic buildings to perform well in terms of energy efficiency and comfort in both winter and summer, is important. During the summer well-insulated buildings are at risk of overheating (if not effectively shaded and ventilated), with this risk likely to increase with the effects of climate change. This article bring insights into the necessary measures to control overheating, by modelling different Passivhaus standard buildings over a range of future climate scenarios.

ICEERB 2016 | Healthy Housing

The 7th International Conference on Energy and Environment of Residential Buildings (ICEERB) will focus on Healthy Housing. The conference's programme facilitate research exchange between academics and support and facilitate dialogue with industry (housing providers) and government (housing regulators).

 

Conference themes include:

 

Sustainable design and construction:

 

Making bio-based construction materials mainstream: ISOBIO project

 Back to basics - Setting the path towards making bio-based materials mainstream: opportunities offered by nature are facing cultural, technical and market challenges

 

 

The University of Rennes hosted the first regional stakeholder workshop for the ISOBIO project on 4 February 2016. It brought together academia and research stakeholders to tackle the main challenges of the project’s objectives and to explore opportunities offered by bio-based construction materials.

 

What are the advantages of a common heating supply for several buildings (local district heating system or district heating system)?

By connecting several buildings to the same heating system the number of heating generation systems is reduced to one. This usually saves investment costs. Additionally there is in general a smaller total peak load than the sum of all separate peak loads by the included buildings. Not all buildings will need their peak load at the same time. On the other hand the heat distribution system, large pipes in the ground, will generate additional investment costs and additional thermal losses. In many cases local district heating systems and district heating systems include waste heat (e.g.

New city quarter Neckarpark Stuttgart heated from waste water

In Stuttgart’s new Neckarpark district, the energy in the municipal waste water is used via a trough heat exchanger and a heat pump to supply low-temperature heat through a local heating network. In combination with highly energy efficient buildings (undercutting the minimum energy performance requirements by at least 45%) this will lead to a very energy efficient district. Stuttgart’s Neckarpark is one of the demonstration projects in the research initiative “EnEff: Wärme” of the Federal Ministry for Economic Affairs and Technology.

Five German model regions to showcase the energy supply of the future

Smart Energy Showcases – Digital Agenda for the Energy Transitions (SINTEG) is a funding programme for the use of smart technology to link energy generation and consumption by using innovative grid technologies and operating principles. In total €230 million have been assigned as funding for the model regions over a period of four years. The showcases shall be a blueprint of smart energy structures that can be implemented on a large scale across Germany.

 

Heating buildings with capillary tube mats in exterior wall

Researchers from the Saarland University are currently testing the use of capillary tube mats in exterior walls to heat buildings. So far, capillary tubes have been integrated in interior walls, ceilings and underfloor heating systems. Now six millimetre thick tubes are mounted to a concrete façade and are covered by a mortar layer with a high thermal conductivity. A final layer of insulation will be added on top.

dena German energy agency rewards "Refurbishment Heroes"

The German energy agency dena is rewarding home owners for their interesting energy-efficient refurbishment stories. The “Refurbishment Heroes” competition is running until 29 February 2016 and includes awards of over € 20,000 for the winners. Applications and eligibility requirements are available at www.sanierungshelden.de. Topics and content of the stories are not limited, however they have to be true and linked to energy-efficient refurbishment.
