Description

Services offered:
 - Consultation on solar thermal heating system design;
 - Dynamic simulation of solar thermal heating system efficiency, particularly with regard to warm-water utilization profile and large-scale systems;
 - Building envelope optimization, particularly with regard to thermal bridge-free construction, detailing, material specifications;
 - Dynamic 3D building simulation;
 - Daylight simulation and optimization;
 - Optimization of solar heating devices;
 - Determination of air permeability of buildings (BlowerDoor test);
 - Thermographic survey;
 - PHPP2007 calculations and client-side PHPP2007 calculation support and verification.
The expertise of the proposer is research and development on highly efficient energy use.

Advantages

Energy Efficient Building Core Laboratory is able to provide information on building energy demand and indoor climate parameters during the design process that helps to make important decisions that affect later operating costs and inhabitant comfort.

Its main advantages over organisations offering similar services in neighbouring countries are experience in modelling buildings, concentrating the competence about passive houses and low energy buildings and connections with competence centres in Austria and Germany. Advantages over competitors in EU15 countries (except Finland) include the speed and price of the service.

Innovative aspects (ecologic, social and economic)

Environmental Aspects
Energy efficient buildings have positive effect on environment through reduced energy consumption for achieving the same or better level of comfort for inhabitants.
Social Aspects
Energy efficient buildings have good thermal comfort and natural light levels in living and working spaces which has important effect on inhabitant health and productivity. On bigger scale energy efficient buildings reduce the amount of money spent on maintaining thermal comfort in living spaces by a household thus having general positive effect on economy and wellbeing.
Economic Aspects
Increased energy efficiency significantly reduces building operating costs (heating, cooling, lighting energy costs) and thereby increases the independence from purchased energy.

Application examples

Public and private buildings.

Cost

The services enable to achieve considerable energy efficiency during building use (minimal heating/cooling loads, maximum daylight use etc) with little or no extra costs on construction.
Planning and construction of highly energy efficient buildings can be subsidized by different national and/or European funds.
