BUILDING ORIENTATION :: ENERGY EFFICIENCY :: THERMAL COMFORT The following is a brief overview of site and building orientation. Many problems associated with energy and the indoor climate are a function of the site geography and its climatology, and above and below grade geology and hydrology; as well as how the building is orientated on the site in relation to the prevailing flows of natural forces and by-products of man made inventions and interventions. INFLOOR RADIANT DESIGN GUIDE For hydronic underfloor radiant heating systems, the systematic design process can be described as a 12 step program beginning with the heat loss and ending with the head loss. This topic is part of our P rofessional Development curriculum. Step 1 - Heat Loss, q (Btu/hr) per zone. Heat loss influences everything in the design process.
