| Construction / Commissioning |
Although the solar systems were designed and modelled as per the requested specification by the engineers, the client brief and information provided was ultimately incorrect. When the buildings were occupied, the daily hot water consumption was higher than designed for. Solar system performance was therefore low as backup heating was regularly required to maintain hot water temperatures. An upgrade was thereafter commissioned by the client which included heat pumps as backup in order to reduce the daily kWh consumption of the systems.
