What does Building Performance mean for you?
Return on Investment
Factor4 supports owners and managers of real estate portfolios both at strategic and operational level.
Factor4 assesses building performance based on the user’s well-being. We focus on the main comfort parameters: temperature, acoustics, air quality and light.
Factor4 is the architect of the energy efficiency project in your organisation.
We help organisations to comply with national and international regulations and standards related to energy efficiency and building performance.
Every day, we see buildings that do not perform. They consume too much energy, maintenance costs are too high and people living and working in them are unhappy, unproductive or even sick.
We believe buildings can perform better: they can be more efficient and more comfortable.
Performance contracting is a very powerful tool in upgrading and managing buildings.
Business as usual is not good enough.
We don’t sell equipment or materials. We develop improvement projects and focus on the result. We are prepared to take our responsibility and share the investment risk.
Our customers are SME’s, large companies, communities, schools, apartment buildings, energy cooperatives and public authorities.
We provide solutions from start to finish, covering all relevant techniques.
We participate in several research projects related to innovation in the field of performance contracting and energy efficiency.
