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.
