This paper suggests a method how to predict electric lighting energy savings for photocell controls in daylit spaces taking manual blind control into account. The method predicts lower but supposedly more “realistic” lighting energy savings than conventional simulation approaches. On the other hand, predicted savings are larger than those predicted by ASHRAE 90.1 power adjustment factors. The m...

This article presents and discusses the lessons learned from monitoring of 25 integrated daylighting electric lighting international case study projects. The studies consist real occupied buildings that have been monitored as part International Energy Agency (IEA) SHC Task 61/EBC Annex 77 Programme. general goal was to balance energy use with occupants’ visual non-visual requirements. achieved ...

A novel semi-transparent building integrated photovoltaic (BIPV) laminate was developed and introduced in this paper. It produced by cutting standard mono-crystalline silicon solar cells into small strips then making electrical connections between each strip before laminating the two layers of glass. The overall energy performance saving potential BIPV insulated glass unit (IGU) under real worl...

This paper introduces a computer-based tool for the analysis of the geometry and the daylighting of Byzantine church domes to facilitate experimentation with a number of cases before any fieldwork is undertaken. Starting with a geometric derivation of the relationship between dome parameters, the digital tool builds an interactive three-dimensional model of a Byzantine church dome. The model al...

the susceptibility to terbacil of six randomly selected strawberry cultivars (‘aromas’, ‘chambly’, ‘harmonie’, ‘kent’, ‘la clé des champs’ and ‘seascape’) was analysed using chlorophyll florescence (cf) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. terbacil was applied at one of five rates...
