These can then be arranged on the site according to the engineers’ predefined rules e.g.
Rapid grid decarbonisation and the use of high efficiency heat pumps results in extremely low carbon emissions and gives clients the option of going net zero in operation through the use of additional PV or green electricity tariffs.When coupled with building mounted renewables, it can deliver low to non-existent energy bills to occupants, with some designs capable of being cost negative over the course of the year..
Excellent Occupant Experience: Both Passivhaus and Bryden Wood believe that environmental performance should not come at the expense of occupant experience.This is reflected in the designs targeting both the Passivhaus Thermal Comfort criterion as well as CIBSE TM 59, which ensures adequate thermal performance.. Resilient and adaptable to different climate conditions: Passivhaus also provides additional resilience by adopting a design based on passive design strategies coupled with technological solutions that can easily be upgraded, refurbished and replaced.Whilst Passivhaus was originally developed for residential buildings in Germany, the standard and its principles can be adopted in all kinds of building types, locations and climatic scenarios, and respond to the effects of global warming..
However, there are four important challenges for the adoption of Passivhaus:.Increased design cost and complexity: It requires specific detailing of the envelope, high quality of construction and specific performance testing in order to get the building certified..
Increased capital cost: The additional construction capital cost can vary from 8% in the most optimistic scenarios (Passivhaus Construction Costs – October 2019) up to 25%..
Increased programme: Delivering a Passivhaus building can take longer.If you wanted a 5-year pay back with such a saving, you could afford to invest over £600Billion.
There is a direct synergy between financial return and moving to renewable energy..The payback, the value generated for doing the right thing on the environment is immense, in monetary terms and in our living environment and in protection of people and biodiversity; and in feeling that we are part of a generation that acted and made the world a better place for everybody.
These are things in our power and reach.We can reap the hard-won benefits of technology and freedoms while at the same time repairing the world..
