Background
Quality program
In 2005, Växjö municipality sold land in the area called Biskopshagen to Växjöhem AB. Växjöhem AB were interested in building housing units on the land. The municipality had expressed a number of requirements through a quality program, which Växjöhem AB had to fulfil in order to build on the land. The aim of having the quality program and the requirements is to ensure the quality of the buildings and the surroundings.
Requirements
One of the requirements in the quality program concerns the level of energy consumption per square meter during the operation of the buildings. The total energy consumption is not to exceed 90 kWh/m².
Another requirement in the quality program concern individual meters for hot and cold water, heating and electricity. The meters have to be installed visibly in every apartment to make the inhabitants aware of their energy consumption.
There are also requirements on district heating; the buildings have to be connected to the local district heating system.
All of the requirements are very specific and easy to follow in a checklist. In the municipality quality program it is assumed that most of the requirements will not bring extra costs if they are considered early in the planning process.
Sesac
Växjöhem AB is involved in the project Sesac (Sustainable Energy Systems in Advanced Cities). Sesac aims to demonstrate how a more sustainable local energy economy can be achieved through the implementation of energy efficiency measures in new and refurbished buildings. It also aims to increase the use of renewable energy sources, technology and systems for electricity supply, as well as for heating and cooling systems.
The buildings on Biskopshagen are part of the Sesac project. Through the project Växjöhem AB is committed to carrying out continuous metering of energy consumption in the buildings when taken into operation. The total energy consumption is not to exceed 85 kWh/m² BTA.
