The Renewable Energy Research Team of the CTU UCEEB has prepared a technical study for the real estate company M.E estates
on the heating and cooling of the Sabina, a residential ship to be anchored on the Vltava River in Prague's Holešovice district
and used for rental housing.
For the residential ship Sabina, we have performed a computer simulation of selected zones to balance the performance for
space heating and cooling, hot water preparation and the associated annual energy demand. To simulate the energy behaviour
of the assessed building, we used hourly climate data for three different years (reference: with average conditions for Prague,
cold with an energy-intensive winter period and warm with an energy-intensive summer period). This allowed us to define the
range of heating and cooling capacities needed in real operation for the following design activities.
The study also included the design of the capacity of the heat source - a water-to-water heat pump - for space heating and
cooling and hot water preparation in the building and the assessment of an energy balance for its operation, including the
requirement for a bivalent heat source. Together with the design, the concept of the heat pump interconnection with the heat
and cold distribution system in the building and the heat and cold recovery from the river flow was recommended.
