Where do we get fresh air, how do we bring it in, how do we treat, cool and heat it, how do we distribute it and how do we expel it whilst recovering our energy? 

For multi unit and commercial developments, how do we meter and resolve energy billing, centralised or local plant? 

How do we heat it, heat pump, chiller, chilled beams, passive, ducted, Green Star, NABERSNZ? 

Do I need a resource consent for plant location, how do I get maintenance access, will it fall on me in an earthquake, will it become redundant? 

How much will it cost, what are the pros and cons, any maintenance considerations and what about sustainability - can I have a system that doesn’t cost the earth? 

How do we make sure it will be quiet, how do I make sure there are no draughts, how can we coordinate with the architect and structure to make sure it all fits?  

Can someone design me the complete swimming pool package? A solution for every project - commercial, medical, residential, hospitality, civic, industrial, prisons, education, specialist laboratories and explosives.  

Our multi-award winning experts have you covered.
