He is co-founder of CELA (Climate and Energy Laboratory in Architecture) actively involved in the environmentally conscious design of buildings, urban spaces and new materials. During his M.Sc. and D.Sc. studies he dealt with the development of design tools for energy-conscious and sustainable architectural design in a two-fold level: building, and urban scale. Among others, he developed SustArc (Sustainable Architecture), a model based on knowledge and procedural methods that serves to determine a "space of solutions" for the creation of architectural design alternatives, dealing with climatic, energetic and environmental aspects at the residential quarter's scale. Lately he developed SunTools, a SketchUp plug-in for Daylight and Solar Access consideration during early architectural design stages.
