Reducing the energy demands of buildings
The energy performance of buildings is a theme with which our company has been involved for over 10 years. This widely discussed topic is currently gaining importance in the context of the rising price of energy, decreasing costs for the acquisition of materials and technologies, and also with the evolving legislative environment, putting increased requirements on buildings.
We are active in all stages of project preparation and the implementation of specific projects as consultants in the area of optimising the design of new buildings or renovations, as well as at the level of preparing legislation related to energy management in buildings and their energy intensity – primarily the transposition of European legislation, in particular the Energy Performance of Buildings Directive EPBD II.
We are also involved with the issue of increasing the knowledge and skills of workers in the construction industry with regard to energy-efficient buildings, where much more stringent requirements are placed on the quality of work.
Our activities in the field of preparing legislation relating to energy intensity and the efficient use of energy reach beyond the Czech Republic – above all in the EU as a whole, along with the countries of the former Soviet Union and South-eastern Europe.
When low energy or passive houses were the subject of early discussions in the Czech Republic, we managed to find partners and clients with whom we carried out a number of specific examples of smaller low-energy apartments and family houses. At the same time, we managed to demonstrate that with a suitably designed optimised design, the houses can be built with an absolute minimum or even no increase in investment costs, while reducing heating costs by almost half.
Our goal is to find the optimal solutions for clients that lead to a reduction in the energy performance of their buildings, whilst the costs incurred are reasonable with the maximum benefit in the long-
Determination of reference values for energy systems in buildings
In order to correct and specify some of the inputs to the evaluation of the energy performance of buildings (EPB), SEVEn’s research team, initiated by the MIT, defined the new values of so-called guideline numbers for the area of technical building equipment (TBE). The guideline numbers are essentially reference parameters of the efficiency and energy consumption of different types of TBE ( from heat sources through lighting to ventilation and air conditioning), which were as input variables in the model calculations of EPB, if the specific values of a given project are unknown. The outputs of this project should be reflected in the intended amendment to Decree No. 148/2007 Coll., on the energy performance of buildings, which currently lists some of this data (incorrectly).
Promotion of the energy policy implementation in Belarus (EU-EuropeAid project)
In cooperation with the German agency KEMA Consulting GmbH and Belarusian experts, SEVEn is analyzing the existing European legislation and regulations of selected EU member states and assisting in finding ways to effectively implement appropriate knowledge of these documents in the legislation of the Republic of Belarus. This collaboration is a part of the European Commission project titled “Support to the Implementation of a Comprehensive Energy Policy of the Republic of Belarus”.
The goal is to compare the approaches of the EU and Belarus and, based on experience, to propose appropriate solutions for the implementation of legislation on energy efficiency in buildings in Belarus. Further, website with relevant documents and comparison of situations in energy efficiency in buildings in EU and Belarus was done. The essential regulation is the European Directive on the Energy Performance of Buildings (EPBD II).
ENTRANZE - Policies to ENforce the TRAnsition to Nearly Zero-Energy buildings in Europe
The objective of the ENTRANZE project is to actively support policy making by providing the required data, analysis and guidelines to achieve a fast and strong penetration of nZEB and RES-H/C within the existing national building stocks. The project intends to connect building experts from European research and academia to national decision makers and key stakeholders with a view to build ambitious, but reality proof, policies and roadmaps.
The project focuses on nine countries (Bulgaria, Czech Republic, Finland, France, Italy, Germany, Austria, Romania, Spain), covering >60% of the EU-27 building stock. Data, scenarios and recommendations will also be provided for EU-27 (+ Croatia and Serbia).
