Kristin Bräunlich | Ventilation in commercial kitchens
A large part of the total energy used in commercial kitchens is devoted to ventilation. A reduction in demand for extract air probably reduces energy consumption the most.

Oliver Kah | Energy efficiency in cafeterias and commercial kitchens
Typical kitchen applications consume a lot of energy and also produce a lot of heat and moisture that sufficiently dimensioned kitchen ventilation systems have to draw out of the kitchen. This article presents the basic interrelations and efficiency potential using a few examples of kitchen appliances.

Tjado Voß | The effect of façade-integrated fresh air elements on energy demand and indoor temperatures in the summer
How do micro-climatic effects on façades in combination with urban and meteorological weather data affect indoor temperatures and energy demand in offices during the summer when façade-integrated fresh air valves are used? Planning recommendations are derived from the answers to this question.

Jan Riha | Highly diffusive overhead lights - heat loss versus energy conservation
A feasibility study on skylights found that diffuse domes can reduce the electricity needed for artificial lighting by 35 to 5 %. Only 3 to 5 % of the ceiling needs to consist of skylights for the workplace to be provided with around 700 lux. An important consideration is that light controls allow lighting to be adjusted in stages.

Matthias Werner | Influence of retrofitting on daylighting
In addition to psychological and physiological effects, optimized daylighting also offers energy benefits. But retrofit projects (reveals or multi-pane glazing etc) can adversely affect daylighting. This presentation demonstrates its impact and potential improvements.
