Green rooftops on school establishments of Thessaloniki

Goal: Improving building energy efficiency and microclimate of the area and upgrading of urban environment, while improving the conditions of thermal comfort and reducing energy consumption.

Children - students, teachers and residents in the area/influence zone of the school, and trespassers from neighborhood districts.

2012 (study), 2013 - 2015 (KAPE evaluation), 2015 (start - end of construction).

The municipality commissioned external consultants for providing services for the Preparation of proposed interventions and documentation for submission acts in the corresponding financial plan: O.P. 1 "Protecting the Atmospheric Environment & Urban Transportation - Managing Climate Change - Renewable Energy Sources" of the O.P. "Environment and Sustainable Development 2007-2013" for Green Rooftops in eight school establishments, by addressing the following: mapping of the existing situation, qualitative and quantitative assessment of the climate problem and the expected improvement in the intervention area, recommendations and intervention budget, predicting the energy savings, proposals, Action Plan (awareness and promotion) for user / audience.
 

The work / services were prepared under the supervision of the the relevant Service and received by the committee.

By Municipality care, the folders for evaluation were submitted to KAPE and the 6 school establishments received positive evaluation. One of them was qualified for a final integration and implementation. The project (for which the completion of control of the tender documents and the integration decision is expected by the KAPE) concerns:
 

  • Installation of multilevel stratification (waterproofing) green roof surface 375m2.
  • Planting 4,065 plants (species endemic of low growth Mediterranean flora of minimum water requirements and maintenance).
  • Irrigation, network installation about 700m with drippers.
  • Construction of traffic corridors - maintenance plants - irrigation.
     

The action carried out in the following school buildings: Kassandrou-Olympiados/26 M.S.,32 H.S. & 23 M.S. (3rd Municipal Community), Dragoumi-Olympiados/32 N.S., 53 P.S.

Collaboration of employees with the competent services of the Municipality: Directorate of Urban Planning and Architectural Design, Directorate of Urban Environment Management, Directorate of Support of Civil Institutions.

Thessaloniki, 8 school establishments (see the description field).

Increasing the proportion of urban green, improvement of environmental conditions, creating ecosystems. Based on simulations and literature review results for the benefit of users / public, are summarized as follows:
 

  • Improving conditions (heating and cooling).
  • Positive results in the internal environment of each thermal zone of the building.
  • Absorption of air pollutants.
  • Increased protection against noise by 8 dB and reduction of reflected sound by 3 dB.

1. Energy, quality and aesthetic benefits in buildings (thus saving energy and resources):
 

  • Energy savings in heating and cooling.
  • Increase in insulation and improved sealing of the building.
  • Extension of life of roof building materials.
  • Reduction of runoff of rainwater from 50-90% to sewer.
     

2. Aesthetic, morphological and qualitative upgrading of the city (quota increase of green surfaces, creating ecosystems) and improved quality of life.

3. Reduction of the phenomenon of "urban island".
 

4. Upgrading of school infrastructure and the immediate environment (in synergy with other actions under the School Housing Program).
