The Passive Solar Potential of Skylights

Research shows that, even in cloudy areas, a large chunk of our heating needs could be met with a few well-positioned (and well-managed) skylights. “I’ve been interested in passive solar heating for quite a number of years, but we live in a cloudy climate. And there has been a lot of skepticism about how well … Read more

Passive Solar Greenhouses in Ladakh

Ladakh has a long and harsh winter season when temperatures hit as low as -30°C (-22°F). These long winters reduce the cropping season to barely four or five months in a year. Other factors include low precipitation largely in the form of heavy snowfall, high wind velocity, sparse plant density, thin atmosphere with high volumes … Read more

Insu-ram Blocks Resemble Beetle Wings

Insu-ram is a system of assembling blocks inspired by the cells in the wing covers of certain beetles that allow internal air flow to circulate. Insu-ram both cools and insulates a space from external heat without the use of machinery. The external pattern of the block generates a micro-shading effect that reduces the solar contact … Read more

More about Embodied Carbon of Building Materials

Following on my last post about designing highly sustainable buildings, I would like to delve a bit deeper into why I think it is important to analyze the embodied carbon footprint of buildings. This video assembled by the Endeavour Center in Canada presents the facts very graphically and succinctly. And there are more resources available … Read more

Designing Highly-Sustainable Buildings

Earlier this month I participated in a webinar titled Designing Highly-Sustainable Buildings featuring the Sketchup software team, along with Sefaira, a plugin that calculates various aspects of energy use pertaining to the design. A representative from an architectural firm that uses the software explained how they go about their designing, which is mostly for commercial … Read more

Report from Natural Building Event in Moab

I’m standing on the Community Rebuilds campus. Today they’re hosting events for the Natural Building Conference, a gathering of those interested in construction using materials like straw bale, soil and lime mortar… which is being mixed now. Moab has a housing problem… like other tourist-orientated towns in the region. Amanda Jane Albert is an instructor … Read more
