Social Sustainability in Practice

Wednesday, September 16th, 2015

Today, it is the task of averting drastic climate change that might be described as an experiment – a vast social experiment in decision-making and democratic action. Success in that endeavor will not be determined primarily by large techno-logical fixes, though many will be needed along the way. Just as decisive to the outcome is whether our social relationships, cultural beliefs, and political customs will allow for the kind of changes that are necessary. That is why the climate crisis is as much a social as a biophysical challenge, and why the solutions will have to be driven by a fuller quest for global justice than has hitherto been tolerated or imagined.

Building performance assessment - iiSBE Canada project to close the loop between theory and practice

Tuesday, September 17th, 2013

iiSBE Canada, the Canadian arm of the International Initiative for a Sustainable Built Environment [iiSBE], an independent, non-profit group committed to advancing the sustainable building agenda within Canada, has taken up the challenge of developing the knowledge base about the performance of leading high-performance Canadian green buildings.

CEU Article - TOP TEN ways to get a greener building

Tuesday, April 2nd, 2013

Building designers care about climate change, and they care about the quality  of the spaces they are designing, but opportunities are rarely fully capitalized upon to make their buildings better. From our perspective, that of a sustainability consultant and part of a national engineering firm, there are many ways that all building designers, be they engineers, architects, owners or managers, can improve the sustainable nature of their building project. We offer this guidance from a viewpoint  locked in real business practice, rather than that of a hardcore environmentalist [even if some of us are]: sustainable approaches MUST make sense to the business community  or they will not be adopted. So here are our top 10 ways a building designer might achieve  a greener project  - in no particular order.

Beyond regional material credits - Advancing the quest for truly sustainable design

Wednesday, December 12th, 2012

Local product sourcing receives a lot of attention in green building rating systems, but the geographic limit it imposes considers only the transportation impacts of material selection. It does not take into account all the other potential  environmental impacts that form part of the overall ecological profile of a material. Standardized life cycle assessment is essential for a true understanding of how sustainable building products and materials really are.

Public building makes a statement with energy and water savings

by Jim Taggart

The 1,600 sq.m office and conservation centre has cut the need for potable water by 70%, and passive heating, high-efficiency boilers, and heat recovery ventilators have reduced energy use by 42%. The building has become a destination to learn about LEED construction, and best practices in water conservation and on-site septic treatment.


Understanding Sound Masking

Saturday, July 26th, 2008

An installed sound masking system is almost indiscernible to occupants.

Just as with light, temperature and humidity, there is a comfort zone for the volume of sound in an occupied space. It is determined by the noise floor, or the level of continuous background sound. If the noise floor is too high, the environment is irritating and tiring. If it is too low, other occupants’ conversations are easily overheard and noises cause distractions.
Acoustically, green buildings present additional challenges because the strategies that help with daylighting, natural ventilation and temperature regulation also tend to lower their acoustic performance. (more…)

Acoustic Design Performance in Green Buildings

by Doug Kennedy and Mike Noble

The increasing concern for energy efficiency and other green building strategies, as codified in the LEED Rating System [as well as other rating systems], considers many aspects of indoor environmental quality but does not explicitly provide credits for good acoustical design. (more…)

heat recovery

for high performance buildings

The Earth Rangers Centre uses earth tubes and a double foundation wall. The energy recovery in winter and summer is sufficient to temper the air about 5º C on average and up to 10º C on cold days.
by Richard Lay

It has become increasingly common to provide heat recovery on ventilation systems in buildings. In fact, it is difficult to achieve the minimum energy performance requirements for a LEED or other high performance building without it. (more…)
