Occupied, office hours
Offices, professional services, clinics and showrooms. Predictable weekday load, lighting and heating dominate, and the rating matters most because these are the buildings that get let.
A clear weekday shape. Demand climbs before the first meeting, holds through the day, and falls away in the evening, with very little at weekends. Lighting, small power and heating account for most of it, and the heating side moves with the season rather than the hour.
A predictable weekday load matches generation reasonably well, though the roof is usually smaller than the demand. The bigger lever is often the rating: offices are the buildings most likely to be let, and the minimum standard rises, so fabric and plant decisions carry a lettability consequence as well as a bill consequence.
The ones this building type tends to suit. Each is still read against your building before anything is proposed, and a measure that does not suit yours will say so.
Heating and cooling running against each other in the same hour. Plant left on a timeclock set for an occupancy pattern that no longer exists. And a rating close to expiry, which is easier to deal with before a letting than during one.
Add the building and its rating. The gap between where the rating is and where it needs to be usually decides the order of the work.
