Beligische Passivhaus-Regionen

Brüssel - Region Brussels-Capital

Besonderes Augenmerk unter den Passivhaus-Leuchtturmregionen verdient die Region Brussels-Capital, welche seit 2010 alle öffentlichen Bauten und ab 2015 sämtliche Neubauten in der Region Brüssel nur noch in Passivhaus-Standard errichten lässt. Damit setzt die Region Brussels-Capital bereits um 6 Jahre früher konsequent den Standard um, den die EU-Gebäuderichtlinie erst ab 2021 als Mindeststandard vorschreibt. Um die Entwicklung in Schwung zu bringen konnte man mit dem „Call for Proposals for Exemplary Buildings“ binnen 3 Jahren 117 Objekte mit 265.000 m² in Passivhaus-Standard initiieren, vom Mehrfamilienhaus, über Schulen und Kindergärten bis hin zu Bürobauten.

Minister of Environment & Energy - Interview of Mrs E. Huytebroeck

"On 3 March 2011, the Brussels-Capital Region passed an order amending the decree of 21 December 2007 establishing the requirements and methodology for energy performance in buildings. The content of this draft order aims at immediately setting the passive requirements for 2015 and modifying some of the shortcomings related to the method of calculating the PEB.

Regarding passive, Article 5a provides that from 1 January2015, individual PEB dwelling units will present:

• a net heating requirement of less than 15 kWh/m² per year;
• a primary energy consumption for heating, hot water and electrical accessories of less than 45 kWh/m² year;
• an air-tightness under 50 Pa less than 0.6 renewal per hour;
• an overheating percentage beyond 25°C less than or equal to 5% for the time of year.

Furthermore, Article 6a provides that from 1 January 2015, PEB Offices and Services units and PEB Education units will present:

• a net heating requirement of less than 15 kWh/m² per year;
• a net cooling requirement of less than 15 kWh/m² per year;
• a total primary energy consumption less than [90 - 2.5*C] kWh/m² per year. Defnitions have been made of the compactness, i.e. the ratio between the protected volume and surface leakage [m³/m²];
• an air-tightness under 50 Pa less than 0.6 renewal per hour;
• an overheating percentage beyond 25°C less than or equal to 5% of the time of occupation.

The objective is already to give a clear signal to developers, architects and design firms for buildings whose application for planning permission will be submitted after 31 December 2014.

Antwerpen - Beacon project "Nieuw zuid"

General description

Right next to the historic city centre of Antwerp, a brand new residential quarter – Nieuw Zuid or ‘New South’ – will be developed. There, the integration of living and working will become reality. Works for this ambitious and multifunctional project are scheduled to start in 2013. This former railway yard will be turned into a high-quality neighbourhood. The 70 ha large area, which today is vacant for the largest part, will comprise of housing, local shops, public facilities and offices. The finishing touch will consist of a park with a surface area of over 15 ha. Sustainability will be a key element in the development of Nieuw Zuid. The focus on water-, energy- and waste management displays the ambition to develop Nieuw Zuid as a best practice example of sustainable urbanism. The implementation of a district heating system on renewable energy sources, possibly in synergy with its environment, is currently being studied. - First large-scale development in Antwerp following passive house energy levels. - Possibly first implementation of district heating network in Antwerp, as first step in developing city-wide network in the long term - Looking, under the direction of city of Antwerp, for a model of cooperation with private developer (on building- and site level) and third parties (on site level for implementation of district heating) Project team: Private market development initiative in close collaboration with the city of Antwerp and AG Stadsplanning Antwerpen.

Energy efficiency and use of renewables

• heat: maximum 15 kWh/netto m².year heat demand, and this from the start of the development
• cooling: only passive cooling in residential buildings, in offices cooling demand restricted to maximum 15 kWh/netto m².year
• renewable energy: roofs or other building parts are where possible equipped with photovoltaic panels or other technologies for the production of renewable energy
• each building and unit within is equipped with smart digital meters
• each building will be equipped by the district heat net company with a supply set with heat exchanger for connection to the district heat network. The private developer pays a connection fee to the net company worth the supply set with heat exchanger and the saved cost of natural gas net construction and connection.
