Introduction

The best practices serve as a showcase of good examples and should be a first step to acknowledgment of new solutions. The section includes solutions and best practices that are in line of the Toolkit focus and were implemented in the building sector.

Best practices are comprised of the following resources:

  • best practices that were collected from project partners, who identified them basing upon their experience they had from their region (project deliverable D.T1.1.1).
  • best practices that are actually implemented by CitiEnGov Project partners and were collected during study visits in CitiEnGov regions.
  • accomplishments that arrived from synergies of CitiEnGov project partners and existing European initiatives, projects and platforms that have a focus on renewable energy sources and energy efficiency.

List of best practices

Energy management system in the city of Ferrara

Location

Municipality of Ferrara, Italy

Description

Municipality of Ferrara showed the use of data at municipal level for implementation of energy strategies. The importance of energy data is linked to urban planning and environment, especially to specific actions, from refurbishment of public buildings to planning and monitoring activities. Collected energy data and software can used to match planning needs and public administration processes, enabling a better energy performance in a medium/long-term period. The images show collection and harmonization of data at local level. Collection of energy data in buildings and spatial information like shape, height, number of units, volume, age, type, energy consumption, heating system types.

Energy management system in the city of Weiz

Location

City of Weiz, Austria

Description

Working consequently on energy issues and having energy data at municipal level is what Weiz has set up to do. The city of Weiz has decided to work with real data based on the size of the city of having about 11.300 inhabitants and about 450 energy supplied buildings. Having a good energy data basis is a result of (1) a survey of private households in the year 2013-2014, (2) the adjustment of this field research with existing data in the municipality and (3) the adjustment with statistics. The main challenge regarding energy management are (1) keeping the level of data quality (actualizing the data), (2) harmonizing them with existing data of the municipality (different tools and data basis) and (3) identifying/developing the “right” tool that could include future issues.

Complementary activities of CitiEnGov and mySMARTLife project

Location

City of Bydgoszcz, Poland

Description

The implementation of the CitiEnGov project is complementary to the activities that the City of Bydgoszcz is performing in the mySMARTLife project. mySMARTLife is a project funded under the European Union’s Horizon 2020 research and innovation programme. Activities will take place in the three lighthouse/advanced cities, where they will implement integrated, smart solutions in 3 areas: energy in buildings, transportation and CT. One of the results of the CitiEnGov project, which aims at energy data harmonization, is an energy database. This database will provide data on energy consumption (electricity, central heating, gas and water) of municipal public buildings (e.g. schools, municipality offices). This might be used for Replication of Advanced Integrated Urban Planning methodology, for example:

  • where an energy model (demand and supply) will be identified to create a 3D modelling,
  • for simulations of energy demand for the next 10 – 20 years.

Gemini house

Location

City of Weiz, Austria

Description

The idea for the Gemini House comes from the Austrian programmer Roland Mösl. He presented 1993 the vision of a house that rotates with the sun on the Innovation Fair “Eureca” and won with it the gold medal. 2001 after years of planning the Gemini House was built within 7 months. The basic idea was to develop a detached one-family house being as sustainable as possible in view of the global environmental situation. The following criteria should be taken into consideration when designing it: No consumption of non-renewable energy, the house should be as independent as possible from the power grid, state of the art building technique and a small space consumption. To achieve a maximum of energy output the following equipment components were used: 40 m² window area to make use of passive solar radiation, 70 m² photovoltaic cells mounted on the roof for generating electricity, excellent thermal insulation in the walls, passive house heating system by using a heat pump, computerised energy monitoring system. The main building material used is wood, because it represents a regional sustainable material that is abundant in the surroundings of Weiz. The Gemini House produces by the active and passive use of solar energy, more energy than it consumes and is a Plus-Energy-House.

W.E.I.Z., First Passive House Office Building of Central Europe

Location

City of Weiz, Austria

Description

The innovative focus of the building is supported by its architecture, construction and energy concept. The W.E.I.Z. 1 is a compact 3-storey office building that consists of two elements: the offices and the atrium. The atrium hall is the communication area of the building where the lift, the stairs, the corridors, the conference- and meeting rooms and kitchens are arranged. The hygienic air renewal, which is necessary for the offices (avoidance of uncontrolled ventilation, tightness of the building) serves as heating and cooling at the same time. The preheating of the air takes place in the earth register, the after-heating takes place in the cross-air-to-air-heat-exchanger. The heated air is introduced to the offices through air diffusers. The consumed air is introduced through excess-current-grills from the offices to the atrium, which is heated with the consumed air. This outgoing air is centrally collected and on the other hand, heats the inlet air in the cross-air-to-air-heat-exchanger. The same system is used in the summer to cool the building.

Implementation of energy management system in Kindergarten Divaca

Location

Goirška region, Municipality of Divaca, Slovenia

Description

Within a new building of Kindergarten Divaca an energy monitoring and targeting has been introduced. Within a first phase, energy data monitoring was based on energy invoices and invoices of water consumption. In the later phase, the monitoring was upgraded with the installation of meters of heat consumption and remote data reading. This allows energy managers to follow the energy targets. Establishment of excellent cooperation between municipal administration and local energy agency as their energy manager enabled prompt and efficient intervention for eliminating errors in energy use (for example: identification of inappropriate heat pump operation, reduction of excessed water use from automatic irrigation).

Health centre Kranj - weather-forecast controlled heating

Location

Kranj, Slovenia

Description

The service eGain forecasting™ provides the system for weather-forecast controlled heating. It optimises the heating in the building on the basis of a professional and detailed weather forecast that includes temperature, precipitation, wind direction and speed, sun radiation, angle and reflection. The system receives weather forecasts via the mobile network (GSM/3G) and is connected directly to the existing heating system. The forecast receiver produces a temperature equivalent (Teq), which replaces the traditional outdoor temperature as the heating system’s guide. Graphic tool gives customers and energy consultants the opportunity to work with energy data and to influence the calculation of the energy balance for each building. Self-learning optimisation of the energy-balance calculations is now being applied in the system so that energy-balance calculation is continuously improved each day during the heating season.

ARPAE RES H/C Spread

Location

Regions: Castilla y Leon (Spain), Emilia Romagna (Italy), Riga (Latvia), Rhodope (Bulgaria), Western Macedonia (Greece) and Salzburg (Austria)

Description

Running from 2014 to 2016, the RES H/C SPREAD project has developed six regional pilot plans in the field of heating and cooling with renewable energies, in order to harmonize baselines and therefore allow better policy planning. The project involves six pilot regions (Castilla y Leon in Spain, Emilia Romagna in Italy, Salzburg in Austria, Riga in Latvia, Western Macedonia in Greece and Rhodope in Bulgaria) representing the main climatic zones in Europe, primarily in the Mediterranean area. These pilot regions have benefitted from procedural and methodological support in developing their own plans for the optimal use of renewable energy for heating and cooling. Special attention has been devoted to improving participatory governance, enabling the collaboration of regional and national stakeholders. In each region, the project has established Country Governance Committees to support the plans’ implementation and to help regional authorities, key stakeholders and citizen representatives reach consensus. The plans have been developed in accordance with the regional demand for heating and cooling and with Energy Efficiency Directive (EED) requirements: “to optimize the utilization of locally available residual and waste sources of heat, cooling and RES through the use of district heating & cooling networks in areas of sufficient heat and cooling demand.” In the long term, it is hoped that the project’s outputs will support the establishment of regional plans in additional areas, by providing an example of best practices for guidance, procedures and planning methods.
