Detailed description of the Good Practice
The Almedalen library in Visby is part of the EUBART(European, Bio-climatic architechture with integrated renewables and real-time user feedback) project supported by the EU in the Fifth Framework Programme (FP5), together with a library in Gloucester, England and a library on Kefalonia, Greece.
The project will demonstrate how bio-climatic buildings with integrated renewables (RES) and building energy management systems with user feedback and control, can deliver significant cost and energy savings, with healthy indoor climate conditions and a high degree of owner/user satisfaction."
"The construction involves
- Heat storage in the building construction
- Highly insulated external structures
- Glazing optimised with respect to the heat loss and cooling load
- Environmentally sound materials
- Renewable energy supply systems
- Sea water based cooling driven by photovoltaics
- A sea water based propane heat pump
- A building energy management system featuring an "Energy Butler" feed back and control system
- Energy efficient lightning with occupancy detection and automatic control
- A low velocity ventilation system with building integrated channels and heat recovery
- "Export" of excess heat to older and less energy efficient neighbouring buildings. "
The overall energy target of the building is 100 kWh/m2&year and the final goal is an energy self sufficient building wherer the electricity needed for lighting and heat pump et cetera comes from the solar panels integrated on the buildings roof and from small scale local wind power.
The indoor climate has high priority in the new Almedalen library. The indoor thermal climate shall be comfortable both for visitors and people working in the library.
The environmental awareness has been high during the whole construction process. Not only concerning energy matters and air condition but also in the choice of building material.
An environmental programme is accepted for the construction work, the building and it's surroundings. The environmental programme is part of the quality programme for the whole building project.
"General and overall environmental aimes are
- The consumption of natural resources shall be minimised
- The use of non recyclable natural resources shall be minimal
- The solutions shall encourage environmental commitment among staff and students
- The buildings can be shown as good example of resource conserving and environmental friendly building and operation.
- The area shall be characterised by the assets and limitations in use of natural resources that are specific for Gotland."
- climate change
- sustainable building
- renewable energies
Objectives of the Good Practice
The objective was to meet FP5´s goals: to reduce CO2 and other greenhouse gases by reducing energy demand in buildings through the use of cost-effeective, energy efficient space heating, cooling, ventilation, lighting systems and integration of renewables into buildings.As well as by improving the acceptability of renewables, and thereby speed up implementation of RES in buildings in Europe.
Funding of the Good Practice
The project was funden within EU FP 5
