Builders Book and roasting residents

Fitting bricks: it may seem scary to use BIM but the rewards are great

September 26, 2016 | Richard Lupo
We’re told that when a bricklayer first walks onto a building site, the first thing he or she does is not lay any bricks.  They spend quite a bit of time working out exactly where the windows should be.  This is because they want to position them exactly such that there is a neat half brick / whole brick pattern around the window frame.  A very neat aim, but surely this is all on the architect’s drawing.  Well, apparently not.  Not, that is, unless the drawing is created under a Building Information Modelling (BIM) regime.  A BIM drawing would show bricklayers exactly where the windows should be to create the desired, neat effect.  This can save nearly a day of bricklayers’ time on site and serves as just one example of how BIM can cut costs on site.

New build 10% cheaper, loads of % better – using BIM

Three steps to resolving London’s housing crisis

May 17, 2016 | Arianna Sdei
A recent report commissioned by the housing charity Shelter encourages the release of green belt land to respond to the housing crisis in London, concluding that redundant brownfield sites cannot possibly deliver the expansion targets that the mayoral candidates have promised to deliver. The population in the capital is expected to grow by nearly half a million in the next decade and the mayor’s own assessment suggests that 50,000 homes per year will have to be built to meet the need, more than double the recent build rates. We support steps to up the build rate to this level as Sadiq Khan promised.

28 home passivhaus scheme subsidised by council – how it was built

April 19, 2016 | Arianna Sdei
The UK Government Construction strategy has two challenging targets for 2025. These include an expectation of 1.7- 2.5 million new homes and 50% less carbon by 2025.  The UK’s 26 million existing homes also need to change.  The Climate Change Act targets require homes to be improved to emit 90% less carbon by 2050. So each home built to higher standards helps towards that goal and also, of course, helps with comfort and lower bills for residents.

Free CPD on PassivHaus design principles

March 22, 2016 | Sustainable Homes
  Using Passivhaus design principles for new build homes and refurbishment can dramatically reduce carbon emissions, cut residents’ fuel bills and improve general health and wellbeing.  But what are Passivhaus principles?  What’s involved?  What are the costs?  What are the benefits to the landlord?  Sustainable Homes has been alerted to a resource that may help with getting these questions answered.  What’s especially useful is that the resources is free and comes in CPD format, so will be useful to building professionals.

Delivering quality and cost effective new build homes

February 9, 2016 | Sustainable Homes
Now more than ever we need to be building new homes. The UK Government has set the ambitious target to build one million homes by 2020, this means building a minimum of 250,000 new homes per year; an uplift of over 100,000 homes. This represents a huge challenge for the sector.

Opportunity for involvement in national research on new build performance

September 23, 2015 | Sustainable Homes
There is increasing attention being paid to design versus as-built energy use. Some homes that were built to higher standards were tested and found not to be delivering the energy performance that had been specified – sometimes significantly underperforming. Understanding the reasons behind this ‘performance gap’ is vital to ensuring that new build homes are warmer, more comfortable to live in and cheaper to run.

Landlords to contractors: “Prove your green credentials”

August 3, 2015 | Sustainable Homes
The proverbial man from mars would not have to look far for evidence that humans are taking seriously the threat to their planet of climate change. No annual report, CSR statement or ad campaign is nowadays complete without an environmental statement of intent. But he may be puzzled to read this proliferation of earnest literature in conjunction with dire warnings about the consequences of a global temperature rise of 4 degrees C. Which should he believe?

As 2016 target ditched, first apprentices start on groundbreaking zero carbon development

July 23, 2015 | Sustainable Homes
SHIFT accredited A2Dominion, the lead developer at UK’s most sustainable development NW Bicester, has welcomed its first young construction recruits on site. Willmott Dixon, the contractor on the scheme, recently hired its bricklayer apprentice and completes the initial weekly college student placements. The NW Bicester masterplan will encompass up to 6,000 highly energy efficient new homes.

Mind the performance gap… small details, big difference

July 14, 2015 | Sustainable Homes
Getting the small things right can mean as much as an 2-3 extra SAP points ‘Retail is detail’ as Philip Green likes to say. The same is true for retrofit. According to a recent study, ‘poor detailing of the wall connecting joints can mean energy loss through the joints may even be greater than that through the entire window.’ Poor airtightness and thermal performance around windows is a significant problem; with convection accounting for 50-60% heat loss in buildings, this can have a significant impact on SAP calculations and CO2 emissions.

Tackling overheating in homes: The big picture – New Findings

June 15, 2015 | Sustainable Homes
New homes are being built and retrofitted to meet higher thermal efficiency standard. These include improved air-tightness and fabric insulation, which can increase the risk of overheating if steps are not taken alongside this to enable excess heat to be easily removed. Moreover, the expected increase in the frequency of heat waves and future rises in average external temperatures as result of climate change are likely to drive more cases of overheating in our homes.

BIM: What is it and how it’ll change how you build

May 15, 2015 | Sustainable Homes
Tom Jarman, Environmental Sustainability Co-ordinator at SHIFT landlord Your Homes Newcastle, looks for the substance behind the hype – and how it could be used to build more sustainable homes.
