World Green Roof Day’s Post

This is an awesome example - the saying a “picture paints a 1000 words” springs to mind. Imagine green roofs all over buildings in our cities, especially in areas where there is lots of concrete, hard surfaces such as asphalt and a lack of greenery. Green roofs can help to mitigate the urban heat island effect, make cities cooler and more liveable and help to encourage biodiversity. #greenroofsnz #greenroofs #urbanheatislandeffect #livingroofs

🌡️ Ever noticed how some buildings heat up or cool down quickly? This could be due to the use of low thermal mass materials. When the dry resultant temperature inside a building respond quickly to changes in the outside dry bulb temperature it might suggest that the building materials have a low thermal mass, meaning they don't store much heat. Why does this matter? Well, buildings with low thermal mass can struggle to maintain a stable indoor temperature, leading to increased energy use for heating and cooling. What are your experiences with thermal mass in buildings? Have you noticed a difference in temperature stability between buildings made with different materials? #ThermalMass #BuildingMaterials #EnergyEfficiency #BuildingPhysics

Wondering about insulation for your building? Consider factors like climate, usage, and budget to determine whether insulating your roof, walls, or both is the best choice for optimal comfort and energy efficiency. #Insulation #EnergyEfficiency #BuildingTips #Steelbuildings #metalbuildingsystems #steel #prefabricatedbuildings #preengineeredbuildings #steelindustry #steelconstruction #estructurasmetalicas Casey Lemhouse

How does this sound? A roof that's both beautiful and energy efficient all year long. Metal roofs that are cool roof rated can lower energy consumption by minimizing heat transfer, and reduce the energy needed to ensure a comfortable temperature inside the building. The power of metal goes beyond sunny days; they also excel throughout seasonal changes, from high winds to snow and storms.

A failure at a transition in the building enclosure could result in an increase in energy consumption, moisture intrusion, or a reduction in occupant comfort.

Heat pumps size & shape depend on various factors such as: ✅heating & cooling load space requirements ✅installation space ✅energy efficiency goals ✅climate conditions of the region #application #installation #heatpumps Read more here: https://lnkd.in/e-hVC2ck #heatright

Does Your Building Have Effective Insulation? ✅ Good insulation is essential for reducing energy costs and extending the life of your building. Buildings often lose most of their heat through external walls. By choosing high-quality wall insulation, you can: 🔻 Lower your energy bills 🔻 Reduce heat loss 🔻 Help stabilise temperature fluctuations 🔻 Improve soundproofing 🔻 Lower levels of condensation  🔻 Increase the lifespan of your walls Perfect for housing associations and contractors, our services are designed to future-proof your buildings using cutting-edge technology.

1/2 The winter chill has set in across the country, so what better time to discuss passive ventilation and condensation management? Condensation, a naturally occurring phenomenon, can only ever be managed, and not completely eradicated. Buildings are now starting to be designed with these principles, however, I still get two very different conversations from roofers and builders with anecdotal experiences dictating their decision making every day. The first is; 'I've never had a problem before, why is the industry forcing change?' And the second is; 'I need help managing condensation as we've had some issues in the past and I want to ensure that we deliver the best product for our clients.' Both comments are vehemently opposed and yet both can be true. The fact is condensation occurs in roof spaces. Its unavoidable. However, sometimes, simple roof design and a climate where the roof has the opportunity to dry is all it takes to manage the condensation effectively. The new standards take on a climate zone approach to mitigate the condensation in higher risk areas. It's always important to note that just because one house didn't show the impacts of condensation, it does not mean the next won't.

2/2 Similarly, I often have clients from colder climates contact me and say something like; 'I definitely want to cool the roof in summer but I want to close off the ventilation in winter.' The problem with this statement is a lack of understanding of condensation and the potential issues this approach can cause. Whilst positive marketing messages regarding energy efficiency get through to end users, little is commonly known about the impact of condensation and even less about heat and cooling load. To understand this, let's wind it back a little and discuss how people live in 2024. In colder climates most people leave windows and doors closed, particularly in winter, and the heater is run at times to take the chill off. However, rarely do people run the heater at all times in the home because quite simply, its easier and cheaper to just throw on some warmer clothes rather than constantly run a heater. Also they are more acclimatized than the northern states to the cold and are just used to the cold weather. In summer however, all bets are off. Melbourne, Adelaide and Perth can be absolutely intolerable at times. Consistent 35-40 degree temperatures and whilst this might only last 8-12 weeks, the AC gets blasted and the cooling load is excessive. A recent passive ventilation case study revealed that in some of the biggest variance areas of Australia, the annual cooling load is reduced by as much as 30% whilst the annual heating load only is increased by 5%. Keeping that in mind, let us move on to the nationally approved energy efficiency rating system, NatHERS. NatHERS is a livability scale which is why it is so variable. Essentially how it works is this. Lets say you lived in Cairns and your house is frequently, unbearably hot, and very basic in its energy efficiency design. How much energy would it require to take that house and return it to the same scale of comfort? What products would need to be installed to reduce the energy required to get back to that same number? How much of an impact will those products have? Now lets take that house and move it to a different climate zone but the target doesn't move. This may require a completely different building method to achieve the same result and this is energy efficiency in a nutshell. Ultimately its important to manage condensation, and to be energy efficient, but they don't always have to be mutually exclusive. Passive ventilation is one of the only ways to effectively impact both in a positive direction. Build for sustainability. Build for longevity. Build with a client first approach.

Future heat waves will kill power & AC—and people. Passive strategies can lessen health risks of an extreme heat scenario while reducing power demand and making a power outage on top of a heat wave less likely. Read on.
