As global summer temperatures rise, more buildings are installing energy-hungry air conditioners – a major contributor

As global summer temperatures rise, more buildings are installing energy-hungry air conditioners – a major contributor to climate change. But are there ways to cool buildings down without turning the AC on? At first sight, the view could be mistaken for the rolling hummocks of Hobbiton, right down to the perfectly circular doors opening out of the lush green hillside. But the doors are made of glass, and inside them are not cosy hobbit holes but an array of large mechanical steel arms and levers holding some of the doors ajar. These hills are part of the roof of the California Academy of Sciences in San Francisco, US. The undulating green roof is one of a series of engineering and design features that make the academy one of the largest passively ventilated spaces in the US. This means that even in the peak of summer, the bulk of this building relies on clever manipulation of the elements to stay cool, with next to no air conditioning. Roofs like these are one way that architects, engineers and designers are rethinking buildings to find ways to keep them cool without air conditioning.

Amazon’s has a 27% Discount on a Honeywell Portable Air Conditioner

With so much news about climate change and pollution, it’s saddening to know that the air indoors may be harsher than it is outside. With temperatures on the rise, a portable air conditioner poses as a fairly more affordable complement or alternative to either centralized air conditioning or your existing air conditioner. An added advantage to portable air conditioners like Honeywell’s Contempo Series is that it comes with a dehumidifier that filters the air you breathe. Amazon’s discount on the Honeywell portable air conditioner (HL09CESWK) cuts the cost by 27%, so you only pay $330 instead of $450. Plus, you may even opt to get another $50 off by applying for an Amazon Rewards Visa card.  With 9,000 British Thermal Units, the Honeywell HL09CESWK can cool rooms up to 300-400 square feet. Aside from beating the heat, the dehumidifier can reduce about 80 pints of moisture along with impurities such as dust, pet dander, and hair daily while a bucketless operation is possible through its self-evaporation system. Equipped with a washable dual-filtration system, you can rest assured that your portable AC is built to last. Also, the filters shouldn’t add to your cost since it can eas...
