HMR Pathfinder

Posted by: Adrian Slatcher | Comments Comments Off

The Pathfinder Project is aimed at improving the local environment in the economically deprived areas of Oldham and Rochdale. Old and unsustainable housing will be improved or replaced, to help improve quality of life and reduce environmental impacts. A range of financial assistance is offered, to make sure local residents can access the new homes. This 15-year project will spend over £2 billion in the Oldham and Rochdale area over this time. Since 2004, more than 1600 existing homes have been improved, including improving the insulation. Many new sustainable developments have been built, including the award winning homes at Selwyn Street. Parking and community safety has been improved in some neighbourhoods.

Ekoviikki – Ecological Housing Area in Helsinki

Posted by: Adrian Slatcher | Comments Comments Off

Due to the strong commitment of the City of Helsinki for improving the environment and enhance sustainability, the City Council decided to built an ecological building site in the Viikki area, a new science suburb of Helsinki.
Ekoviikki is situated a mere 8 kilometres from the city centre of Helsinki. The Ekoviikki site provides housing for 2,000 inhabitants and represents a built area of 64,000 m2. Multi-criteria decision-making criteria have been applied to account for different aspects of sustainability in the city, site, and building planning. In that way, it has been possible to introduce innovative environmental and energy concepts in the housing area.
The largest solar projects in Finland are realized at Ekoviikki covering more than half of the buildings. Eight building integrated solar heating systems with a total area of 1,246 m2 produce 15 % of the total heating demand of the housing area and half of the DHW load in 400 apartments.

Rokpa Trust – Samye Ling solar water installations

Posted by: Adrian Slatcher | Comments Comments Off

The Kagyu Samye Ling Buddhist Monastery and Tibetan Centre was established in 1967 and is the largest of its kind in the Western world. The Monastery is located on the banks of the river Esk. As well as being a centre of Buddhist wisdom and learning, it also offers the highest standards of Buddhist teachings. It is also the a centre for the preservation of Tibetan, arts, medicine and culture.

The Samye Ling centre receives a standard 25,000 visitors each year including 2,000 – 2,500 school children and groups of teachers. The Ropka Trust has made a main concern that centre become carbon-neutral in respect of its energy use as soon as possible as oil, LPG and electricity being the current energy uses.

The Green Building

Posted by: Adrian Slatcher | Comments Comments Off

Constructed with environmental sustainability high on the agenda, the Terry Farrell-designed Green Building is located in the Macintosh Village, in Manchester’s ‘Southern Gateway’, just off Oxford Road. Every aspect of the construction and maintenance of the building has been aimed at providing the highest environmental standards, with energy efficiency of the highest priority. Day-to-day energy consumption is minimised ‘passively’ through the design of a highly energy-efficient envelope wrapping the structure of the building, and ‘actively’ through installing highly efficient plant and equipment for heating, ventilation and light.

The scheme consisted of external improvement works to 12 properties within a maisonette block built during the 1950’s, situated at Ranby Avenue in the Charlestown area of Manchester. The maisonette block is of a ‘Wimpey no-fines’ construction, (solid concrete walls) with a pitched roof. The block was in need of major modernisation to both the external and internal areas. There are two communal staircases serving the upper properties which benefit from a communal lighting system. The single glazed windows were in poor condition throughout. The rear area of the block was quite poorly lit and considered to be a security risk by the residents.

“Green Roofs” in school buildings

Posted by: Adrian Slatcher | Comments Comments Off

The “Green Roof” program is a pilot implementation of light-structured horizontal and vertical green surfaces in school buildings, as a low-cost example of upgrading their energy behaviour and appearance, which could be easily adopted by citizens and implemented on all types of public and private buildings.
Wishing to avoid the likelihood of having to reinforce the structural system of existing buildings in the seismic area of Thessaloniki, which would be necessary in the case of adding vegetation and soil on top of existing flat-roofs, the “green roof” program introduced the idea of creating light wooden or metal structures (pergolas) over the roofs of existing buildings, where climbing plants may develop on stainless steel grid structures.

The Municipality of Thessaloniki submitted to the Ministry of Development a proposal, accompanied by all the necessary studies, to gradually substitute heating oil by natural gas in all the school units under the Municipality’s jurisdiction. The proposal was submitted within the framework of the Operational Programme “Competitiveness” that is co-financed by the European Commission and was approved. The project’s 1st phase concerned the connection to the natural gas network of 48 school units and has already been completed since November 2006. The 2nd phase, concerning the remaining 56 school units, is expected to be completed by September 2008. The project was extended in order to also include 17 non-educational municipal buildings, including gyms, kindergarden units and offices.

In 2008, the project of “Modernization of the district heating system in Plonsk“ was successfully implemented. The results calculated were fund to be impressive. The coal consumption is lower with a result of c.a. 70% , the annual CO2 avoided emission is estimated at 35,000 Mg/year, the emissions of particular matter is expected to decrease by c.a. 76,7% etc.
The main tasks of the project were: the replacement of the coal boiler to the biomass type version, the establishment of the cogeneration system, as well as thermo-modernization of the existing heat distribution system. A new combined heat and power system is expected to supply 67% of the total heat demand, as well as generate 11 MW of renewable energy. To supply the biomass demand, there are c.a. 50-70 new job openings in the region (in the agriculture and service sectors).

The buildings’ interior spaces present significant variations of temperature, due to the absence of insulation, resulting in big energy losses during winter and overheating during the summer period. Therefore it was necessary to transform their exterior shell, in order to remedy all problems of inadequate heat / sound insulation, poor ventilation and defective windows. The three buildings were fully insulated on the outside by extruded polystyrene panels and brick cladding, while all of the existing windows were replaced by double pane insulated windows, in order to reduce energy losses. The roofs were reconstructed by re-using the existing materials (wooden structure, roof tiles), after the installation of appropriate thermal and moisture insulation materials. New windows were opened on the northern facades to provide for cross-ventilation in order to avoid high temperatures during the summer. Permanent metal shades were specially designed for the southern facades for further solar and glare protection of the openings. The installation of a sound-absorbing acoustic tile ceiling reduced the reverberation problem experienced in the classrooms.

CEMACAM –TORREGUIL. Bioclimatic Building

Posted by: Adrian Slatcher | Comments Comments Off

This is a building that is integrated into the environment. It is equipped with thermal insulation throughout the building foundation and to the passive air capture, cooling and penetration systems which minimizes the consumption of energy for climate control.
The air, which is pre-cooled several degrees below the outside temperature, provides constant flow, exchange and renovation as it heats. The type of arch structure and the roof-top air shafts enable the air to evacuate and the circulation of the new fresh air that enters.
The main lighting system is natural light that penetrates the buildings by reflecting on its walls through the skylights, which are equipped with automatic light regulation systems. When the natural light descends, it is progressively compensated with artificial light, thereby obtaining the same light threshold both day and night.
