Primary School 27 separates apartment from heating system
Primary School 27
Background
Before the improvements were made, the school was not insulated and was connected to district heating. In 2000-2001 new PVC-framed windows were installed and a new heat exchanger with automatic regulation was connected to the heating system.However, within the school was a habitable apartment and this too was connected to the heating system. Consequently the entire school was heated long after the children and staff had left, in order to keep the occupants of the apartment warm.
Building details | |
| | |
| Type of building: | school with sport hall |
| | |
| Year of construction/ Floor area/ Operating hours: | 1976/ 3180 m2/ 50 h |
| | |
| Heating and cooling / measures installed | central heating only |
| | |
| Energy label/CO2 emissions | The school’s energy rating was improved from E to D and it now operates using 279 kWh/m2/a, emitting 89 kg CO2/m2/a |

ProjectDescription | |
| | |
| Aim | Primarily to reduce heating costs. |
| | |
| | |
| Key points | Experts from within the Council led the project, drawing on external specialists for specific technical requirements. The communication campaign is ongoing. It includes discussing the results of the project with key decision-makers within the Council and throughout Energy Cities Polish Network. The project is also being showcased by the Display Campaign; Towards Class A.
Other energy projects underway in Bielsko-Biala include Energy Monitoring of all public buildings in the town, ‘SchooBIE-Do – a new educational centre for renewable technologies, and “Low” Emissions - a programme reducing low-level smog through the replacement of coal-fired boilers with cleaner, more efficient heating systems. |
| | |
| | |
| Reason for inclusion as Shining Example | This Shining Example demonstrates that simply by separating the on-site apartment’s heating system from that of the school, significant improvements in energy and emissions performance can be achieved (from E rating to D rating for energy consumption).
This was a low cost improvement with a very short payback, and is replicable in many schools, as the incorporation of apartments within schools is quite common (especially in Eastern European countries). |

Costs&Benefits | |
| | |
Costs &
funding | Cost: €4000 - Financed by the City Council)
Payback time: 6 months |
| | |
| Benefits | CO2 emissions avoided: 20 kg/m2/year
 Money saved: circa €8,500pa
Energy saved: 197,000 kWh per year
Ecological benefits: decreased about 63,400 kg CO2 per year in local thermal power plant
Change in behaviour: Increased awareness that substantial savings and reductions are achievable through simple, cost effective investment.
Decision-makers are now more likely to involve specialists in decision making prior to investment. |
| | |
Partners&Roles | |
| | |
| Partnership details | The project was realised without specific partners, but will be promoted using Energie Cities Polish network, and will be disseminated more widely via Display. Display’s calculation tool and energy label have been reported to be very helpful. |
| | |
Recommendations | |
| | |
| Achievements | Obstacles overcame:
Social and financial difficulties associated with separating the apartment from the school.
Decision-makers concern over using external specialists
Monitoring and evaluation structures:
Performance data captured in the school’s energy invoices are now regularly transferred to the Council’s administrative office and fed into a monitoring system.
The Council now uses Display’s web-based labelling tool to evaluate buildings, and a new, in-house labelling tool is currently being tested.
Successes:
Very short payback time
Cash saved can be put to other uses (circa €8,500 p.a.)
Permanent monitoring system in place
New, in-house labelling under development,
Increased energy efficiency from class E to class D |
| | |
| | |
| Lessons Learned | This example may convince decision-makers to separate apartment heating in some way from the main school installation or adopt other measures (e.g. remove the entire apartment) in order to improve heating efficiency. |

Frankfurt am Main: Small CHP plants provide heat and electricity |

Frankfurt’s Carl von Weinberg School is one of 15 buildings involved in a project realised by the City of Frankfurt in 2000. Since, 18 gas fuelled cogeneration plants aliment the buildings with electricity and heat.
