Barvikha office centre

The first-class office building nearby Luxury Village and Rubliovskoe shosse represents the character of an International 6*-VIP Business Club. It offers impressive office spaces as well as luxurious lounge- and private dining areas, a business club, restaurants, shops, banking and travel agencies, all based on a sustainable and energy saving concept. 15.000 sqm above ground area of high level comfort will be equipped with newest technologies to

• minimise energy consumption
• use energy efficiently and
• maximise on site renewable energy production

The compact design with an atrium in the heart provides best possible ratio of envelope to areas and reduces thermal transfers to a minimum. The double skin façade complies with user’s wish of natural ventilation, whereas protecting from weather and noise.

Conditioning SystemChilled Beams and Overhead Ventilation

As commercial tenants become increasingly aware of benchmarking assessment methods like DGNB, LEED and BREEAM (UK), which assess a building against various environmental benchmarks, they realise, that usually used conditioning systems, such as the four-pipe fan coils, portend further drawbacks.

Potential future government legislation aimed at, for example, reducing carbon dioxide emissions, will hit hardest occupants of buildings with energy-extravagant systems.

Chilled beams have a higher cooling capacity than chilled ceilings. For a cost only slightly higher than fan coils, chilled beam or chilled ceiling systems offer a high degree of comfort, low carbon dioxide emissions and a good environmental rating.

Geothermal Energy

Boreholes + Ground Source Heat Pumps

The heat pumps take heat from (or to) the common heat sink water circuit that passes through pipes tied into the reinforcement cages of the 8m deep foundation piles beneath the building.

The piles provide an excellent heat sink for the following reasons:

• The ground is around 10ºC in winter and less electricity for the heat pump is required to extract heat from this than from the air which might be as cold as –10ºC.
• The ground is around 12ºC in summer and it is a more efficient sink than ambient air which might be as warm as 25ºC.
• The piles are required for structural reasons so the only extra cost is for plastic pipe and labour.
• It avoids the use of roof-mounted, air-cooled heat rejection plant that can be noisy, expensive and difficult to get planning permission for.

Photovoltaics

Power from Photovoltaics is the most widely available commercial method of generating electrical energy from renewable sources. The use of solar energy through photovoltaic systems poses a real alternative to conventional electricity production. Furthermore to use the building skin as part of ‘on site’ energy generation can prove a long term economical and environmental investment.

Solar Water Heating

Solar Energy for water heating represents one of the simplest ways of utilising so-called renewable energy sources in a building. Even on a cloudy day there is considerable energy that can be extracted from the sun.

Solar panels are most appropriately employed to reduce the energy used for water heating mainly because the demand for hot water is almost constant throughout the year.

The demand for hot water that cannot be met by the solar panels can be provided by a conventional gas boiler, an instantaneous gasfired calorifier or an immersion heater.

FuelCell

Fuel Cell technology produces very low emission rates, the cell generates high electrical efficiency and the exhaust air consists of water vapour, nitrogen and residual oxygen while is free of noxious gases as nitrous and sulphur.

This system produces up to 30% more electrical power in comparison with conventional energy generation.

Fuel cell systems produce Power, Steam and Hot air, provides decentralised energy generation and is environmentally friendly.
