AGORA

As Finland paves the way as a leader in the drive towards a more sustainable Europe, the Guggenheim Helsinki will become a symbol for progress and an example for achieving sustainable cities.The Agora is a centre for artistic talent and free expression. At the same time it is a hub for the energy flows of the city and will be a place where locals and visitors alike flock to learn about environmentally concious design.Renewable energy production on-site using heat pump and solar technology converts the building into a power plant. Instead of drawing energy from the city grid to the building it is possible to actually provide heating and cooling to the rest of the city from the building during most part of the year.

Many systems and design features integrated in the building design help to reduce energy consumption and environmental impact. The adaptability features ensure that this landmark will be able to change constantly to meet the needs of the future. The building is designed to meet high sustainability standards. It will exceed the criteria of LEED Gold rating.

Some of the features that help to reach this high standard are:• Locally procurred wood materials (FSC certified from Finland)• EFC or Earth Friendly Concrete produced on-site uses cement alternatives (70% carbon emission saving)• Water collection and reuse for the green roof irrigation and flushing toilets• Parking spaces limited to only special needs visitors, provision of bicycle racks and proximity to public transport encourages green transportation • The building is designed to reach the near zero energy (nZEB) levels of energy use:How to achieve this:• Good thermal insulation in the building envelope• Heat pumps with an energy buffer to balance daily heating and cooling load fluctuation• Heat pumps to produce heating and cooling from the sea• Air quality monitoring for optimized ventilation rates in all spaces• Heat recovery in the ventilation system• Use of natural ventilation in the summertime in parts of the building• Maximizing use of natural lighting and minimizing solar gains with controllable façade shading system• Green roof• Photovoltaic electricity generation• Solar heating for hot water

EXTENSIVE GREEN ROOF

FAÇADE SYSTEM

-Reduced heat island effect

DESIGNING FOR THE FUTURE

While creating enjoyable outdoor space,

the green roof has many positive environmental effects.

-The soil works as insulation and so reduces heat loss

-The soil and planting create evaporation

during the summer reducing cooling needs

-Reduced rain water run-off

Photo-voltaic electricity generation is integrated in the design of the building.A ‘solar garden’ is located on the roof for harvesting light, electricity and heat generation for the needs of the building as an alternative to non-renewable fossil fuel energy sources.

Photo-voltaic technology is also integrated into the façade of the Green Stack and in the rooftop walkways for electricity generation.

Glass is used in the façade as the main material

Efficient façade design, building orrientation and optimisaiton of glazing position ensure that all spaces throughout the building maximise the use of natural light while minimising heat gains during the long Finnish summer days.

In addition to harnessing natural light through windows and rooflights, optic fibre solar lighting is used in spaces where natural light is not otherwise available. • Achieve 50% energy saving versus just LED or fluorescent lighting • Full control over lighting level and colour in the exhibition spaces

SOLAR ENERGY IN DESIGN

The location of technical spaces is selected for easy maintenance access and eventual retrofitting of new equipment or upgrades. The technical shafts are also design with reservation for expansion and possibilities to retrofit systems.

“Energy tanks”The tanks serve as multi-use space to meet the needs of the present as well as the needs of the future. The construction is a fairly light modular structure which can be disassembled and reassembled to fit new spaces and systems.• Rain water storage from green roof and biological grey water filtration • Air filtration using state-of-the-art synthetic, photosynthesizing chlorophyll impregnated silk protein structures• Electricity storage• Heat pump heating/cooling buffer storage

GREEN STACK: EDUCATION AT AGORAState-of-the-art Building Information Modelling (BIM) used during the concept design will ensure a seemless down-stream passage of information on to the next stage of the project and all the way through to construction.

The design team has planned a predominantly off-site fabrication for all major structures and finishes in order to ensure a smooth construction site.

The use of off-site fabrication will: shorten lead times on materials alleviate a great deal of risk in site processes allow greater quality control

The chimney is a familliar language of the Helsinki skyline. Looking out over one of the many peninsulas around the city from the highly developing Jätkäsaari to the chic urban decay of Kalasatama, one meets the disused smoke stacks of historic power plants. It was a strong con-ceptual theme with the Agora to reinvent the idea of the ‘Stack’ in order to symbolise a new generation of energy for the future Helsinki.

Building on the funtionality of a traditional art gallery, Agora will become a science centre and showcase for excelence in sustainable building methods.Practices and technologies used in Guggenheim Helsinki and in other exemplar sustainable buildings around the globe are on display in an exhibition around the Green Stack and on its viewing deck. Visitors can sense the natural forces harnessed to the benefit of this building by feeling with their own hands the air flow in the ventilation channel of the Green Stack.

in order to have high natural light levels in the interior spaces.

The double façade outer layer is glass with an

electronically controllable texture.

The texture opacity can be changed to control

the level of light that enters the interior.

This feature can also be used to minimize light

pollution during the evening. The inner façade structure

is mostly energy-efficient glazing and at some parts

there is a wood material wall structure.
