The buildings industry is moving towards more energy efficient buildings. Technologies and design can only become so efficient before it is more cost effective to produce energy than to offset that low energy usage. Seems easy enough to imagine but when you get a highly efficient building and energy conservation measures are becoming less impactful at higher cost - and generation technologies are still at a cost premium - is it possible to make a case for a commercially viable net positive building? Industry knowledge for Net positive buildings is growing and projects are breaking ground at an increased rate. This presentation will discuss several key concepts to make the net positive energy building viable in the commercial buildings sector in a cool climate (Southern Ontario). What are the costs? What are the tenant requirements? How do you control the schedules? How do you control the tenants? What are reasonable expectations? Matt Cable led a team of designers, modellers and consultants with a commercial client and has created the business case to build a commercially viable core and shell space that will be Net Positive Energy considering the variable, demanding tenant loads for a commercial tenant. This presentation will discuss the modelling tools, financial analysis and business tools used to achieving this stringent energy target and discus the process of working with a commercial client. Come learn how laptops vs PC’s affects energy use intensity and the number of PV panels required to produce the equivalent amount of energy. Come learn how occupant density and tenant engagement can affect the ability to lease space in an energy efficient space. Come learn how computer programming can be combined with energy modelling to simulate thousands of ECM’s to create the most cost effective building systems before energy generation becomes cheaper. Come learn the business case of Net Positive Energy.
