What are the main benefits of Namai A+ passive houses compared to other houses?
- Heating a passive house requires around 80% less energy compared to the energy costs of a regular residential house;
- The feeling of comfort when living in a passive house is far greater than when living in a regular house;
- The indoor environment of the passive house is suitable for people suffering from allergies and it is also beneficial for healthy people;
- When going on a long trip, you will be able to leave the house unsupervised;
- News about rising energy costs and the energy market will no longer bother you;

Is it possible to build a passive house under Lithuania's climatic conditions?
The percent of energy saving may vary slightly from region to region, but the decision to build a passive house will be a rational choice in any region. Passive houses are popular both in Germany, Austria and Norway located further north.
Are there any architectural limitations for building a passive house at Namai A+?
A passive house may have almost the same architecture as a regular house; there are no essential limitations as for selected materials, height or architectural concept. You may choose a wooden or block house and different construction materials. The only recommendation is to have the majority windows of the house facing south to reduce heat loss.
In what way is the reduction of the heat loss from the Namai A+ passive house is implemented?
Reduction of heat loss in the passive house is achieved by using the latest global knowledge from different fields which are applied in construction. When constructing an A+ grade house, it is not necessary to use very expensive construction materials. What is important in the construction of the passive house is the knowledge of modern construction technologies, right selection of materials and their combination, the modelling of the final result on a computer at the design stage.
It is possible to list some typical technological equipment and materials used for the Namai A+ passive houses that help to significantly reduce the demand for external energy (information resources of the construction partners of Namai A+)
What is the payback period of my passive house?
The myth that the price of the passive house starts from one million is simply not true! Usually, additional investments in such a house amount to approximately 10 to 25% depending on technologies and equipment used. The average payback period of such investments is 4 to 7 years. We are ready to provide individual calculations on the payback of your passive house and, most importantly, we will do it completely free of charge without requiring any commitments! Just contact us!
In what way does the Namai A+ ventilation help protect the health of the house residents?
Have you ever dreamt to have a house where:
- you do not need to constantly open the windows to ventilate the room;
- you cannot get a cold because there are no draughts;
- you do not need to open the windows in winter to ventilate the rooms at the cost of losing valuable heat;
- you are not bothered by mosquitoes and other inspects flying into the house through the windows;
- there are no allergens indoors even in spring because the incoming air is filtered;
- you can fall asleep and wake up in silence because there is no need to ventilate the rooms by leaving the window open.
All the above-mentioned comfort factors may be achieved with the help of the air recovery system which is an integral part of any passive house. It is this system that ensures the retention of heat during cold period of the year, with rooms being ventilated, fresh air coming in from the outside by passing filters and the recuperation system, and transferring heat to the incoming cold air.
You will find more information about air recovery systems on the website of the partner of Namai A+.
Is it realistic to turn the Namai A+ passive house into the active house if the infrastructure adapted to passive houses will emerge in our country in the future?
It will not take much effort to turn the passive house into the active one if the infrastructure enabling the energy acceptance from or transfer to common networks will emerge in the future. In fact, the active house consists of the passive house and energy generating technological equipment. To turn the house into an active one, you will simply need to install technological equipment by connecting it to the existing passive house equipment. However, it still seems to be a vision of distant future the implementation of which will depend on political decision and the country's opportunities to invest in a required infrastructure and make concession contracts with businesses.
What are possible saving methods while building a passive house?
In most cases, people choose a team of builders rather than a well-known construction company for the construction of an individual house or the renovation of residential houses. Such a decision is determined by a great difference in prices, thus the customer cannot afford a well-known contractor. Our company has extensive experience in coordinating the construction of individual houses and has worked with the builders of various levels. Take a look at some stages at which the cooperation with Namai A+ will help you avoid critical mistakes and unplanned expenses as well as to achieve the compliance with quality standards:
Consultation at the land purchase stage
By designing homes and preparing documents required to obtain construction permits, we have acquired extensive experience that we want to share with our customers. Cooperation with our experts at Namai A+ during your land search will help you save money and avoid surprises and give you confidence in making a land purchase decision.
House design (House renovation)
Design is performed by modelling the final result. At the house creation stage, with the help of the PHPP (Passive House Planning Package) software, we may see whether we will have an A++ grade house according to the primary design. Our designers at Namai A+ will select materials and technological solutions to ensure the compliance of the designed house with the passive house standard approved by the Passivhaus Institute, Germany.
A team of partners assist Namai A+ in ensuring professional construction of the passive house. By regularly performing thermographic, indoor micro-climate and other measurements required for the construction of passive houses, we may immediately correct defects by changing technological solutions and aim at constructing the passive house in accordance with works contracts without exceeding the budget.
Our experts at Namai A+ have completed specialized training and hold a certificate confirming our knowledge of the oversight of the passive house construction. If you choose us to coordinate and supervise the construction of your passive house, you will get economical and high-quality construction.
If you choose Namai A+ as the coordinator of your passive house construction, you will accelerate the procedure of house commissioning and receive an energy efficiency certificate for a new or renovated house.
A passive house - is it an individual house with a flat roof?
Each building may be energy efficient whether it is an individual house, commercial or apartment building. Namai A+ not only prepares the designs for new buildings but also performs renovation. The passive house standards do not limit architectural solutions so you may set free your imagination.
What are the first steps in building the energy efficient house?
First of all, we find out your needs because we want you to feel comfortable and enjoy your life. We discuss your ideas for your dream house. Then calculations as to the construction costs of the simple and low-energy house are made followed by our assessment of heating expenses. We provide insights on the longevity of the house value. And most importantly, you get these consultations free of charge! And once you have decided together with your family on your dream house, we will design it professionally!
How can I be sure that my mouse will be energy efficient?
Low-energy houses undergo certification in Lithuania. If the house design meets the set requirements, a certificate is issued for it. However, in order to put you at ease, we perform the technical oversight of construction and ensure the compliance of set standards. We control the construction process, materials and technologies, and provide consultations on house maintenance. We do not tolerate deviations from the design or any cases when the workmanship or material quality is sacrificed. After completing your house construction, we perform all necessary measurements and issue documents certifying its energy efficiency.
Why do people trust the construction of their homes to us?
Probably because we honestly care about each customer. Since 2006, we have been designing individual houses, housing blocks, commercial buildings, apartment buildings and their renovation. During the economic recession, we have not only maintained the pace of our work but also invested in our qualification improvement. In 2010, we were the first ones among all West Lithuanian designers to complete special training in the Passive House Institute, Germany. After passing examinations, we have become the internationally certified passive house designers.
