Testing and Validation of TEKNOsim: A Building Energy Simulation Program.

TEKNOsim is a well-established software tool for simulation of thermal indoor climate. It is used for modelling and simulation of thermal loads, indoor temperatures and thermal comfort. TEKNOsim 5, a new version of the simulation tool has been launched with several new features and enhanced functionalities. This paper presents results of testing and validation of TEKNOsim 5 against two state-of-th

Life-Cycle Cost-Optimized Cooling Systems for European Office Buildings

This study compares the life-cycle costs of various conventional and emerging cooling systems in representative European climates and energy markets. Firstly, cooling demands and energy requirements of a multi-story office building are determined in compliance with local building codes in six different European locations. Life-cycle costs of various cooling systems are then calculated using locati

Natural convection in groundwater-filled boreholes used as ground heat exchangers

In most of the world, borehole heat exchangers used with closed-loop ground source heat pump systems are backfilled with a low permeability grout to prevent water contamination. However, in Scandinavian countries, a different approach is taken – the borehole is sealed at the top and cased down to solid bedrock. The borehole then naturally fills with groundwater in the annular space between the U-t

The Bystander Effect : Mesenchymal Stem Cell-Mediated Lung Repair

Mesenchymal stem or stromal cells (MSCs), a heterogeneous subset of adult stem/progenitor cells, have surfaced as potential therapeutic units with significant clinical benefit for a wide spectrum of disease conditions, including those affecting the lung. Although MSCs carry both self-renewal and multilineage differentiation abilities, current dogma holds that MSCs mainly contribute to tissue regen

Synthesis and crystal structure of trans-dichlorido- [3-methyl-1-(4-vinylbenzyl)-1H-imidazol-3-ium-2- yl-kC2](4-phenylpyridine-kN)palladium(II)

The title compound, [PdCl2(C11H9N)(C13H14N2)], represents a new class of palladium-based polymerizable monomer which could give a potentially catalytically active polymer. It was synthesized via transmetallation from the corresponding silver complex. The PdII ion coordinates two Cl anions, one C atom from the N-heterocyclic carbene (NHC) ligand and one N atom from the 4-phenylpyridine ligand, disp

Periodicities in mid- to late-Holocene peatland hydrology identified from Swedish and Lithuanian tree-ring data

Twenty-five tree-ring width (TRW) chronologies, developed from moisture sensitive peatland trees in Sweden and Lithuania, and representing eight periods during the mid-Holocene to present, were analysed regarding common periodicities (cycles). Periods of 13-15, 20-22, and 30-35 years were found in most chronologies, while 8-10, 18-19, and 60-65 year periodicities were observed as well, but less co
