Environmental and energy standards

• Extra thermal insulation on the apartment building exterior structure
• The building architecturally respects the requirements for optimal building energy use
• Insulating triple glazed windows preventing heat loss and sound penetration from outside
• Sufficiently large windows to ensure daylight penetration in each room in the building
• Air recovery – ventilation with sufficient air exchange
• Air conditioning containing pollen filters to prevent excess humidity and the appearance of mould, mites and other pathogens
• Use of natural building materials which limit the probability of mould or other micro-organisms detrimental to health from occurring
• We avoid the use of slag and fibreglass which could release fibres in our construction materials
• Appropriate apartment layouts with effective ratios of residential and communal areas

Apartment standards

• Temperature in each room is controlled using thermostatic dials on radiators.
• Windows and balcony doors in the SMART LIVING CLB@Letňany building will be plastic with insulating triple glazing.
• The apartment will contain an air-conditioning (recovery) unit with air filtration and heat recovery.
• Heated fresh (outside) air will flow into living areas, while dirty air will be removed from sanitary areas (bathroom, toilet) and the kitchen.
• The hall will contain a separate smoke detector which senses smoke in the room. An alarm is immediately set off if smoke gets into the detector.
• Each room will have wiring for ceiling lamps in place.
• Each room will contain a data socket and shared television antenna socket. Entrance doors to apartments will be fire-resistant and security class 3.

Heat recovery means that the fresh incoming air is heated by the outgoing waste air, reducing heat loss through ventilation. The heat created in the apartment thus remains inside and fresh air from outside coming in is heated to a pleasant temperature.

Every recovery unit also has an additional electrical heating system which is sufficient for heating a low-energy building with minimum energy consumption.

The powerful air-conditioning system with recovery units will replace at least 10 % of the volume of air in your apartment in one hour. Thus over ten hours the air in your apartment is fully replaced, which has a positive impact on the quality of air in terms of carbon dioxide content, smell, and humidity. The whole system can be regulated and its performance multiplied several-fold.

There are two separately controllable branches in the apartment – one secures air outlet from the kitchen, the other from the rest of the apartment. As such, you can, e.g. increase the removal of kitchen steam while cooking at the same time as leaving ventilation of the remainder of the apartment at a minimum.

You will come to realize the benefits of this system from personal experience. We can say, however, that in general it results in improved user comfort in the apartment, and this system has met only with a positive response from users, mainly for the following reasons:

• Air ventilation is not extreme – you avoid temperature differences and this leads to increased living comfort, and is also appreciated, e.g., by plants sensitive to temperature changes
• The fresh air is preheated by the waste air, significantly reducing heating energy consumption
• The exchange of air can be regulated. At minimum performance, 10 % of the air in your apartment is replaced in an hour, securing a comfortable environment free of dust and humidity with imperceptible ventilation
• The air-conditioning system significantly increases the hygiene comfort of your home – you don’t get condensation on your windows, and you prevent the occurrence of mould
• Air removal from the kitchen – the whole room is ventilated, not just the area above the cooker. You can, of course, also purchase a cooker hood with carbon filter securing partial local filtration of cooking smells.
