Short Description
AllboHus had a couple of centrally located 4-storey buildings, constructed in the early 1960s, which were in need of renovation, primarily replacement of main pipes, ducts, drains and electricity cables, etc.
The company wanted to create a sustainable building with low energy usage with the project ‘Eklövet Hus 3’. Adaptation for accessibility was important, as there are many elderly people in the municipality who could be able to live at home longer. Primarily young and elderly people lived in the building in question; there was lower representation by families with children.
The planning of the rebuilding work has taken a long time, as all tenants needed to be evacuated during the rebuilding.
The renovation phase of the project was implemented with commencement during the autumn of 2008 and was finished in 2009.
Key Elements
Work with Residents
Tenants receive a review of how the IMD (Individual Metering and Debiting) system functions when they move in.
Funding
Half of the capital is borrowed and half comes from equity. AllboHus estimates a 50-year payback period.
Thermal Insulation
In this project, façades were provided with supplementary insulation of 10 cm mineral wool and rendering. Attics were provided with supplementary insulation of 50 cm loose insulation fibre.
Windows and Shading
All windows were replaced with energy efficient triple-glazed windows with a U-value of 1.1.
Ventilation
A ventilation unit per apartment was installed.
Heating and Hot Water
District heating provides the building with heating and hot water. Both hot water and heating are metered individually.
Electricity Saving Products
A number of tasks have been performed in order to save electricity. Among other things, motion detectors that control illumination have been installed in all stairwells and all lighting fittings have been replaced and low-energy bulbs have been installed. Individual metering of electricity has also been introduced.
Water Saving
Water saving has also been a prioritised area. Individual meters for cold water have been installed. All taps and toilets have reduced flush volume.
Main Results
Lessons learned
AllboHus is pleased that in this project they devoted resources fully to individual metering of electricity, cold water, hot water and heating in order to reduce energy usage as much as possible.
The company is also very pleased with the accessibility adaptations which make it possible for the elderly occupants of apartments to be able to live at home longer.
To reduce energy usage further, it would be advantageous to install better heat recovery in the ventilation, which was not done.
