Energy efficiency is not only about saving energy when running a home that is already in operation. It also depends on how the whole energy infrastructure has been implemented, how the energy management is actually handled at the design stage and how much attention is paid to savings on the running costs. At the same time the maximum comfort of all the residents of the houses must be taken into consideration.
The first and most important condition is the use of state-of-the-art technologies that increase energy efficiency and improve water management. In the Ctěnický háj project we have taken all of this into account and when building our homes we have incorporated technologies that meet and fulfil the high demands for efficiency as much as possible.
A heat pump is a compact unit not only for heating, but also for cooling and hot water preparation in the home. The pump includes a ventilation unit with two-stage heat recovery, which achieves up to 90% heat savings during ventilation.
The heat recovery unit works on a simple principle, ensuring stable thermal conditions in the house with a constant supply of fresh air that is heated to the desired temperature. Thanks to this you will always have fresh air in your home without the need for opening windows, resulting in minimal heat loss while significantly reducing the possibility of unwanted dust and pollen particles entering your home. Heat recovery also ensures stable humidity. All this is regardless of outside conditions, even the most extreme ones, i.e. during freezing winters or sultry summer days.
The buildings have been designed to minimize heat loss. This is mainly due to the construction of the external walls and floors and the materials used, as well as the roof construction, which contains very effective thermal insulation and a vapour barrier layer to prevent the spread of moisture into the roof structure.
Some windows are fitted with external shutters, which also have the function of the thermal protection of the house. By lowering and tilting the shutters, the amount of daylight in the rooms is easily regulated, which affects the temperature inside.
The system allows rainwater to be captured from roofs and subsequently used for watering gardens and outdoor cleaning.
Thanks to all the technologies and practices used, your energy independence will increase. It’s simple, with no need for you to get involved with the system. Nowadays, there is constant talk about saving water and energy, with the responsibility for this being placed primarily on the end user - i.e. the occupant of the house. That's where modern technology comes in and thinks for you. Responsible and environmentally friendly behaviour is therefore also based on the technology used, not just on whether you leave a lamp on overnight or how often you do your laundry.
As a result, the household is more self-sufficient and uses less energy and water from the infrastructure, thus consuming less of the energy which you pay for and which was obtained from non-renewable sources. In this way you save your money and the environment at the same time.
Investing in environmentally friendly technologies has a quick return, also thanks to contributions from subsidy programmes that can be used. This primarily concerns the New Green Savings Programme. This subsidy programme supports the construction of family houses with low energy consumption, houses that are to a certain extent energy self-sufficient, using eco-friendly technologies, including heat recovery (now also for the use of heat from waste water). It is possible to get a subsidy from the programme in compliance with its terms and conditions. We will be happy to help you with the processing of the application and all related administration.
The Energy Performance Certificate (EPC) of buildings is, in simple terms, the equivalent of the energy label you find on every fridge or washing machine. In the Czech Republic, every newly constructed building has had to have this certificate since 2009. The energy performance of a building can be significantly reduced just by the way it is designed and built. If you are considering the cost of a new home, you should calculate not only how much it will cost you to buy it, but also how much it will be to run it. The houses in the Ctěnický háj project are also exceptional for their extremely low energy consumption - they are of the class "A" rating. Energy efficiency is an important criterion that many people take into account when purchasing ordinary electrical appliances, and when purchasing a new home this criterion is equally important.
Modern, healthy living starts with careful site selection. It's where your children will be growing up, and it can be your home for the rest of your life. For the Ctěnický háj project we have chosen a beautiful location surrounded by nature, on the edge of the city, yet with very good accessibility and all civic amenities. The quality of the interior of your future home is also essential for healthy living. Healthy, airy, modern and well-appointed - these attributes are all met by the houses in Ctěnický háj.
The unique architectural concept of the apartments and houses and the stylish layout of the interiors create a pleasant atmosphere while being very practical. An energy-efficient house can be unique in design and yet provide every possible comfort. The materials used are ecological, high quality, durable, environmentally friendly and as a whole co-create a pleasant place to live.
High-quality thermal insulation of the house, together with the heating and ventilation system using heat recovery technology, ensures comfortable and constant temperatures throughout the year. Whether it is hot or cold outside, you will hardly feel any of it at home. On hot summer days, the indoor temperature will be kept below 27°C, and on cold winter days it will always be above 18°C, even in the case of a power failure. Controlled ventilation with heat recovery ensures a comfortable indoor environment without temperature fluctuations.
Have you heard of heat gain or heat recovery? Although it is often misreported, it is not actually heating but part of a controlled ventilation system, which supplies fresh air to the interior and extracts air from bathrooms and toilets without having to open windows. Thanks to heat recovery, the incoming air is heated by the warmth of the extracted air without being mixed, thus effectively preventing heat loss. The fresh air supplied to the rooms is subsequently heated to a pre-set temperature and dust and pollen are captured as they pass through filters. This makes the system ideal for allergy sufferers, who no longer have to worry about airing their homes during pollen season. The clean and heated air, with dust and pollen particles filtered out of it, ensures a fresh indoor climate with a low CO2 concentration. All this means an end to the fatigue caused by stuffy air and opening windows in winter while wearing three sweaters followed by intensive heating. A controlled ventilation system with waste air heat recovery saves your health and your wallet.
Interior humidity is a big topic. Everyone deals with it in their own way. Some constantly air the rooms, some buy expensive devices that reduce the level of humidity. The average family produces up to 5 litres of water vapour per day. This amount is released when cooking, washing dishes, drying laundry, water evaporating from plants and, last but not least, from us when we sweat and breathe. More moisture production comes from bathrooms when one showers and takes a bath.
Controlled ventilation helps to maintain optimum humidity in the interior, which is very beneficial for the overall climate. It also prevents mould formation and the reproduction of mites and bacteria. Thanks to controlled ventilation, you will breathe clean air at home, free of odours from cooking, pet smells and, most importantly, with no mould spores and dust.
What does it take to have peace and quiet at home? High-quality insulation, triple-glazed windows and a controlled ventilation system, thanks to which, you will only open the windows when you really feel like it. Now you won't have to dream of what is called heavenly peace and quiet, as you'll have it in your own home, and we certainly don't need to convince you of the importance of restful and undisturbed sleep for your health.
An integral part of healthy living is obviously, as mentioned above, the area around your home. Whether you choose to live in a house or an apartment, the sight of the beautiful green vegetation all around you and the opportunity to go for walks or enjoy sports in the charming environment will always soothe your soul. In addition to having nature at your fingertips and gardens and parks in the complex, there is another advantage in the shape of green roofs of the houses, which lower the temperatures in the area in summer simply by not overheating in the sun.
