Energy efficient solutions

We offer our customers comprehensive solutions and development services related to energy-efficient and eco-efficient construction, new technology and new business models. Our services cover the national level, and the review of single products or functions and customary usages.

Our services are used to support decision-making and developing concepts and solutions. The aim of the services is to reduce the energy demand of buildings, products, services or processes to a set target level, and to produce the required energy by means of energy efficient, environmentally friendly solutions.

The energy efficiency of buildings is based on a well controlled concept that covers a building’s outer shell and building engineering, and on the correct use of a building. With controlled solutions, it is possible to safely construct zero or plus energy houses, even in the Nordic climate.

VTT’s offering includes the development and monitoring of functional concepts which are connected with heating, cooling, water supply, ventilation and building automation systems in buildings. The functionality of the solutions can be assessed in the VTT Talo simulation environment, which covers two- and three-dimensional calculation models used in building physics, fluid flow process analysis, and dynamic simulations of the energy demand and consumption of buildings. The serviceability of space, quality of indoor air, and energy-efficiency and lifecycle economy are key criteria for developing energy efficient solutions.

The IEA5 house in Pietarsaari combines outer shell, building engineering and integrated distributed energy production solutions. The energy consumption of the house is only one quarter of that of an ordinary house.
