Ecohousing project group visited Housing Fair 2012 in Tampere, Finland

The Housing Fair is the largest housing and living event in Finland, it is also a significant idea bank and marketplace. Every year, for four weeks in July-August, various living solutions and residential areas are showcased at the Housing Fair. The needs of different demographical groups are taken into consideration at the planning stage and a wide range of building, renovation, interior design and landscaping solutions are presented.

The Housing Fair in Tampere 2012 was the 43rd event of its kind. It was held in Tampere in the district of Vuores between 13th July and 12th August 2012. The fair area had 39 homes that were open to the public and provided an overview of state-of-the-art developments in building design and construction. Examples included an ecological low-carbon-emitting wooden house, a home that supports the wellbeing of its residents, a functional house that is designed for active families with children, a modifiable loft semi-detached house, and a zero-energy house that is self-sufficient when in comes to energy production (The Lantti House).

The area promotes energy-efficient construction and the use of renewable energy sources such as solar power. Waste generated in the area is removed neatly along the unique waste collection pipe system, and energy-saving LED-technology is used in the street and park lighting. Fast broadband connection facilitates smooth distance work. The area will have a high-quality cycling and walking route network and functional public transport services. Storm waters will in the yards and parks be treated ecologically using natural retention and absorption, which protects the lakes in the surrounding areas. Gardening plots can be used to grow vegetables and berries – real local produce.

In the interior design of the houses special attention was given to the functional kitchens of the fair houses. TTS had special stand in the fair where TTS researcher Tarja Marjomaa gave information about kitchen planning and eco efficient housing (EcoHousing project theme) to the visitors.

Ecohousing project group visited Housing Fair in August. The special attention was given to two houses; Lantti House and Tervakukka House. Architect Matti Kuittinen from Kombi Architects (also architect of Tervakukka) presented these houses to the group.

Lantti House: A traditional and modern zero-energy house
The wooden Lantti House combines Finnish building traditions with state-of-the-art technology and know-how. The zero-energy house generates the electricity it needs using solar panels, with heat supplied via solar collectors and district heating. On a yearly level, it even produces slightly more energy than it consumes. 

The Lantti House was designed as part of a one-year intensive programme, Wood Program, focusing on wood and wooden architecture organised by the Department of Architecture /Aalto University. The Lantti House architecture team comprised Pekka Heikkinen, Einari Sutinen and Tomi Tulamo.

Tervakukka and its ecological garden

Tervakukka: An eco-Functional concept home
The ecological wooden house Tervakukka is a low-carbon passive-energy house in which Finnish building traditions combine with the energy efficiency targets of the future.

“Tervakukka is a modern wooden house of which frame and surface materials are made of wood when it’s reasonable from building engineering and economical point of view”, says architect Matti Kuittinen. The building material choices, including gardens, produce as few carbon dioxide emissions as possible. Wood is excellent from an environmental point of view, as it is renewable and sequesters carbon. One cubic metre of wood sequesters when growing about one tonne of carbon dioxide from the atmosphere.

TTS has been participated the planning project of Tervakukka. Also the kitchen and utility room design in Tervakukka has been made by TTS/Heli Mäntylä.

On 28 of March Baltic Environmental Forum and Riga Technical university organized the seminar “Energy performance of buildings and ecological aspects”

“Energy performance of buildings and ecological aspects”,
28 March 2012, Riga

Summary

The seminar „Energy performance of buildings and ecological aspects” covered issues that are important for sustainable development of the housing sector.

Participants were introduced to the recent developments in legislation related to energy efficiency and construction in Latvia. A draft law  on Energy performance of buildings to transpose the requirements of the EU Directive 2010/31/EU is ready and should be adopted by the end of 2012.

Energy audit is an important step in the refurbishment process of the existing buildings. Riga City council co-finances energy audits of multi-apartment buildings in Riga. It is planned that energy audits for 70 buildings will be performed. First energy audit results indicate that average heat energy consumption for heating and hot water is 202 kWh/m2/year. Three main proposals of energy auditors to increase energy performance in typical multi-apartment building include insulation of walls, refurbishment of hot water distribution system, insulation of attic.

Sustainable construction approach should be applied both in construction and refurbishment of buildings. Construction sustainability should be evaluated during all life-cycle of a building (“from cradle-to-grave”) using ecological and socio-economic indicators.

Monitoring results of building refurbishment in Latvia show many mistakes  – short term solutions are applied or solutions that do not lead to significant reduction of energy consumption. Frequently refurbishment works are performed without appropriate construction supervision and inspection. Only complex approach in refurbishment can bring energy savings of about 57%.

Important step is use of renewable energy sources for heat supply. Practical experience –  challenges and benefits of using biomass and solar energy in combi-systems for heat supply of multi –apartment building in Latvia was introduced. There are several preconditions for a successful functioning of the system, one of them is energy efficiency of the building and appropriately selected capacities of the combi-systems.

Monitoring results of indoor air quality before/after refurbishment show that in parallel with insulation measures, attention has to be paid to appropriate ventilation systems in order to achieve comfortable conditions in buildings.

In order to promote good practice examples in construction and refurbishment in Latvia, already a second time a competition “The top energy efficient building in Latvia” has been organized. The most energy efficient buildings in private as well as public sector was nominated.

Within the frame of the seminar a site visit at JSC “Latvenergo” Energy efficiency center in Jurmala was organized. There participants could get acquainted with practical measures anyone can do in order to reduce energy consumption in a household.

The seminar was organized by association “Baltic Environmental Forum-Latvia” in cooperation with Riga Technical University in a frame of the project “Energy efficient and ecological housing” (Ecohousing, http://www.ecohousing-project.eu)

The agenda of event and presentation in Latvian are available here.

Green Meal

Do you know how to prepare your meal in most energy efficient way? TLU and TTS have developed a small game called Green Meal that tests player’s cooking skills and based on the results it gives some tips about how to save more energy and time. During the game player has to make six turns to prepare a meal. As each turn cost some coins then the goal of the game is to spend as little money as possible.

Calculations behind the game are based on the experiment done in TTS. Results of the experiment helped us to decide which combos are most effective and how big difference it makes when using different sizes of hob plates and pots together. At the moment Green Meal is only available in English.

This can be considered a really positive result in terms of visibility and dissemination of the projects results.

One of the main themes presented in this conference was in connection to research of traditional boiler house operation. A research on energy recovery by the use of flue gas condenser was presented in paper “Climate Technology in a Wood Chips Boiler House” by E. Vīgants, D. Blumberga and I. Veidenbergs. Other aspects of the use of boiler houses and other combustion installations were presented in papers „Modeling of Operation of District Heating System” by Ģ. Vīgants and D. Blumberga and „Application of CO2 Taxes for Combustion Installations in Latvia Until 2020” by I. Laicāne, M. Rošā and I.Dzene.

Typical processes taking place within the process of biomass combustion were investigated in research by K. Siliņš, V. Kirsanovs and A.Žandeckis in paper „Air Supply and Fuel Composition Control to Reduce NOx Emissions in Small Capacity Pellet Boilers”.

Another main theme of the conference was innovations and new directions in the field of renewable energy resource use. The benefits and limitations of first real life installation of solar and pellet combisystem for heat energy generation were presented in ”Possibilities of Utilization Solar Thermal Energy for Multi-Family Buildings in Latvia” by A. Žandeckis, L. Timma, D. Blumberga and C. Rochas. Novel flue gas treatment method was researched within “Non-thermal Plasma for VOC Treatment in Flue Gases” by J. Ikaunieks, L. Mežmale, A. Žandeckis and I. Veidenbergs.

In the second day of the conference (13th of October) the session was dedicated to the “Energy sources”. Items and subjects covered different research fields, among the others: Life Cycle Assessment and Impact Assessment, Ecodesign, Clean Technologies, Biofuels, Energy Efficiency, Heat Pumps, Wind Energy, Numerical Simulation, GIS and EU emission trading.

Together 30 scientific papers were presented; 23 researches were conducted in Latvia, including 17 carried out Riga Technical University, one at Latvian State Institute of Wood Chemistry, one at Latvian University of Agriculture, three at Ventspils University College and in collaboration with Lulea University of Technology and one at University of Latvia. In total seven papers were presented by international guests: 5 presenters were from Vilnius (Gediminas Technical University in Lithuania) and 2 from Greece Technical (University of Crete).

The conference has provided a good opportunity for the understanding of the last developments and trends within the use of biomass and other renewable sources in the heating sector.
