CIBSE Guide B0: Applications and activities: HVAC strategies for common building types

This volume, is part of “CIBSE Guide B: Heating, Ventilating, Air Conditioning and Refrigeration”, providing guidance on the practical design of heating, ventilation and air conditioning (HVAC) systems. The guide, released by the Chartered Institution of Building Services Engineers (CIBSE), was published in five separate chapters. The specific chapter focuses on how different types of building and different activities within buildings influence the choice of system (to provide heating, ventilation and air conditioning services).

Researchers develop seasonal sorption thermal storage system for single-family houses

So far seasonal storage systems, mostly realised as hot water storage systems, had to be rather large in order to use summer heat for heating during the winter. Smaller storage systems tend to cool down too quickly. Therefore seasonal storage systems are mostly applied for housing estates or large consumers. Within the SolSpaces project, scientists are developing and testing a new solar heating system including an evacuated tube air collector and a thermochemical heat storage system to store solar heat for the use in winter.

Forscher entwickeln saisonalen Sorptionsspeicher für Einfamilienhäuser

Bisher waren saisonale Wärmespeichersysteme (meist ausgeführt als Warmwasserspeichersystems) sehr groß, um die Nutzung von sommerlicher Wärme in der Winterzeit zu ermöglichen. Kleine Speicher kühlen zu schnell aus. Deshalb wurden solche saisonalen Speicher auch meist in Siedlungen oder für Großverbraucher eingesetzt. Im SolSpaces-Projekt des ITW der Universität Stuttgart entwickeln und testen Forscher ein neues solares Heizsystem das Vakuumröhren-Luftkollektoren mit einem thermochemischen Speicher koppelt.

Integrales Quartiers-Energiekonzept Karlsruhe-Rintheim

Das hier beschriebene beispielhafte Vorhaben des Stadtquartiers "Karlsruhe-Rintheim" ist Teil der Initiative EnEff:Stadt und zeigt auf, wie neben der Kostenoptimierung für die Energiewende auch eine Minimierung des Primärenergieeinsatzes und der CO2-Emissionen erreicht werden. Das Quartier weist derzeit 36 Gebäude mit 1.243 Wohneinheiten auf, die aus den 1950er und 1960er Jahren stammen. Die vorliegende Publikation beschreibt die Ausgangslage in Rintheim, die Vorgehensweise bei der "integralen Quartierssanierung" und die bis 2013 erzielten Ergebnisse.

FlexaNet Street in a Day: a district heating energy revolution

Considering cities account for over 70% of the world’s energy use (half of which are for satisfying thermal needs), district energy networks have an immense role to play in establishing smart, affordable and low-carbon energy solutions. Unfortunately, due to the widespread use of unsustainable materials, incorrect dimensioning, or skyrocketing time and investment costs, the installation or renovation of District Heating and Cooling (DHC) systems have quite some way to go. Thermaflex’ newest district innovation provides solace.
