How To Reduce Mechanical Systems Peak Electric Use By 90%

  1. 1.Use large area radiant systems for heating and cooling

  2. 2.Use ground source heat exchange for cooling and preheating

  3. 3.Use solar thermal for winter heating and summer dehumidification

  4. 4.Use desiccant systems for year round direct humidity control

  5. 5.Use very small, all outside air, ventilation systems


Reducing the peak air conditioning systems electrical load by 90% is required for genuine sustainable buildings.

We must move away from the 100 year old Carrier systems concept where lots of air is recirculated around buildings to heat, cool, dehumidify, humidify and ventilate and where refrigeration is used for air conditioning in the summer and a boiler unit for heating in the winter. Building passive systems work with the climate. Now the building mechanical systems have to stop fighting the climate and start working with the climate.


In order to make this change, we must shift our thinking:

    Separate heating and cooling from dehumidification and humidification

    Separate heating and cooling from ventilation


An Energy Master Plan is the essential tool to ensure new and existing buildings move steadily towards a genuine sustainable energy future.
