Whether you are considering building a new house or renovating your existing home, then consideration of the Passive House concept should be investigated. We are certified by the Passivhaus Institute in Germany and would be delighted to discuss your plans with you. We offer everything from initial consultancy, to PHPP modeling to full ph certification of your house. When renovating, it may not be feasable to do a complete passive house remodel but different components of the ph concept may well be considered. Whatever you are planning, an informed decision will deliver the better results.
