ReNu Building Science

The City of Fort St. John, BC retained ReNu to be the energy modeling and mechanical design lead for their residential Passive House project. Their team is competent, innovative and very diligent in meeting deadlines. Furthermore, they are one of the few firms that truly understand high performance building design comprehensively and also consider, often over looked factors, such as air quality, system noise and maintenance, and hygrothermal considerations. I was also impressed with how informed they are of the latest proven technologies. This project is now a certified Passive House and the northernmost in Canada of its type; ReNu was integral in making this project a success.

I have used Renu twice over the past couple of years. The first job was to determine cost effective performance improvements through passive design & energy modelling at a commercial retail plaza. They were quick to respond to my requests for information and the service fee proposal was very reasonable. The second time I used Renu was for a high performance energy efficiency home to provide appropriate mechanical systems design. Their team worked with my architect to design a great cooling and HRV system. The were professional, approachable, and even connected me to a specialized network of installers.

Marken Design + Consulting has worked with RENU Building Science and Stuart Fix on several high performance building projects since 2012. They have provided comprehensive Passive House and Mechanical Engineering services to our projects in British Columbia and Alberta. We can highly recommend Stuart and his team for any high performance engineering projects.

Stuart and his group are a rare bread of excellent mechanical engineers. They work very well in the low energy building sector including Passive House. Despite the fact they are several provinces away from me I try to engage this firm as often as possible. I would rather hire the best consultant for the job than the closest.

We hired Stuart as a mechanical engineer for a recent design/build on a commercial facility in South Edmonton. Stuart's professionalism, attention to detail and integrated approach to problem-solving was very refreshing and helped the project progress very smoothly through the design stage. I would highly recommend Stuart for any mechanical and building envelope optimization work, whether it be for conventional or high-performance projects.

ReNu energy modelled and provided a high efficiency mechanical system design for a custom home design/build project of ours. The energy modelling report analyzed 4 different mechanical systems from a net energy and net carbon use perspective, incorporating ReNu's recommended envelope specifications and the passive solar gain available to the project. The report looked at the capital, maintence and opertating costs of all the proposed systems including projected energy/utility costs. This economic modelling of the systems overlaid with the carbon and energy lifecycle use of each system but was exceptionally helpful in the decision making process for the project. Prior to our design being started ReNu also analyzed the site and gave recommendation to our design team as to the ideal orientation of the building in order to maximize the passive solar gain available, including the ideal glazing percentage and proper roofline shading angles. I would highly recommend working with ReNu on your project whether it be residential or commercial in nature.

We have and will continue to work with Renu on many different projects. Professional, knowledgeable and easy to work with. Also, very accommodating in regards to different type of timelines and situations.

I have used ReNu on a number of projects. ReNu, particularly Stuart, executed with a great combination of technical theoretical modeling and practical real world execution. He helped me find the best solution for each situation. I would highly recommend ReNu.
