Sun Path Diagram for a net zero energy public library (analysis by Nick Worden and Daniel Overbey, BDMD Architects - Green Dream Team)
With the advent of sophisticated computer modelling software, it is possible to get an accurate idea of how a building design will perform long before the building is constructed. A good suite of modelling software can tell you:
- How much ambient light will be provided by natural daylight on December 21 on a cloudy day?
- What is the effect of adding wall or attic insulation on the size of the heating and cooling system?
- How many photovoltaic panels will I need to balance the energy needs of this building on an annual basis? What if I changed from fluorescent to LED lighting?
- What size of clerestory windows will allow the best natural ventilation and will all parts of the building be adequately ventilated?
- Will the building next door shade the solar panels on my building?
- If I put a white roof on this building instead of a black roof, how does that effect my heat gain and heat loss for the year? What if I put on a vegetated roof?
- How much energy will this building use and what will it's carbon footprint be?
