Greenstone has the knowledge and experience to apply sustainable construction principles to your project, whether it's a basement renovation, a custom home, a retail/office fit-out, or a new commercial building. We believe that construction status quo isn't good enough any more. Advances in building science and an increased sensitivity to the impact of the built-environment on people and the planet have produced better ways to approach the construction process. Here's a list of some of the big ideas we believe in and practice consistently.
1. Energy Efficient Design
Like almost anything, building sustainably can be approached from a number of angles. While we are conversant with a number of green building certification systems (e.g. LEED, Built-Green, Passiv Haus, Living Building Challenge, Boma Best) we also believe that every client's needs are different. Rather than force a particular approach on our clients, we take time to listen and understand their needs, priorities and interests. From there, we can offer advice on the different approaches to building green and assist with making decisions about which sustainable methods or systems makes the most sense for your project. Once those decisions have been made, we apply our experience to ensure that the right trade contractors and suppliers come together to make it happen.
Here are a few of major consideration we typically address when dealing with energy efficiency:
a. passive solar design
b. advanced building envelope assemblies
c. advanced mechanical systems
d. advanced lighting systems
Prefabrication plays a significant role in building sustainably because it substantially reduces the amount of waste generated in the manufacturing process. It also results in a higher quality product because fabricators are taking advantage of a controlled environment and the use of high-tech machinery. Prefabrication also reduces overall construction time requirements. Because of these benefits, we endeavor to prefabricate as many of our component as possible.
2. Construction Waste Recycling
We recycle a minimum of 75% of the waste produced on our sites. We can increase that to 95% if requested and can also provide documented verification of recycling.
3. Locally Sourced Materials
In order to reduce the overall carbon footprint of the construction process, we work with local suppliers for our construction materials. Reducing the shipping distance of construction materials helps the environment and also supports local businesses.
4. Occupant Friendly Finishes
We make use of low-VOC and no-VOC finishes whenever possible. In addition, we source high quality material with recycled content where possible and we can re-purpose previously used materials, saving clients cost and waste disposal costs in the process.
5. Water Management
We encourage our clients to consider options that help reduce the need for water from their municipal supplier. We can achieve this through simple or more complex rainwater capture systems, grey water recycling and the use of more efficient fixtures.
