What you’ll learn By the end of this article, you will understand: how to estimate incoming water demand at feasibility stage the difference between a directly mains-fed system and a stored-and-boosted system how occupancy and sanitary fittings can be used to estimate cold-water storage how loading units can be used to estimate diversified demand why the chosen water-supply arrangement can significantly change the instantaneous demand placed on the external network what infor

How much gas does a building need? When we start looking at the incoming services to a building, one of the first things we may need to establish is how much gas the building is likely to require. This will normally happen fairly early in a project, often at feasibility stage, when we are trying to understand what services are already available and whether they are suitable for what we want to do. I tend to look at these problems using three questions: What are we trying to e
