With buyers willing to pay more for efficient homes, using H+H Celcon Blocks Solar Grade for wall building makes more sense than ever.

Energy efficiency is fast becoming one of the most desirable features of a new home, and one that homebuyers are willing to pay a premium for.

A new survey from Samsung[i] of 1,000 adults looking to move home in the next five years found that almost three quarters (71%) said energy efficiency is a key factor when considering a home and more than half (56%) say it will save them money.

Santander[ii] reported in October 2022 that buyers are paying an average of 15.5% more for a home that meets high energy efficiency standards, with over one third of estate agents reporting that buyers will pay a 20% premium in their area.

For most homebuyers, understanding the energy efficiency of a prospective new home will be done via energy rating systems like EPCs (Energy Performance Certificates). Installing new technologies like PV panels and air source heat pumps will of course impact these ratings. But the building fabric also has a major influence on a dwelling’s EPC rating.

Housebuilders looking to benefit from the higher prices commanded for ultra energy efficient homes need to be taking a fabric first approach. The significance of this has become even more apparent in the 2021 update to the Part L of the building regulations. The changes placed an increased emphasis on building fabric performance and ensuring the precise construction of thermal bridges and junctions.

As better insulation and more efficient heating systems are built into the design of new homes, heat loss from the building envelope becomes increasingly significant in contributing to the overall heat lost from a building. Therefore, getting energy efficiency right in the building fabric is key.

Any H+H aircrete product possesses impressive thermal qualities and can achieve excellent airtightness when used in wall building. H+H Celcon Blocks Solar Grade take efficiency even further however, having been specially engineered to offer enhanced thermal performance over our standard grade aircrete products.

H+H Solar Grade Blocks have a thermal conductivity of 0.11 W/mK and compressive strength of 2.9N/mm2, making them ideal for achieving ultra-low wall U-values in one or two storey dwellings.

Last year Eaton Homes used these blocks in an 89-house development in Cheshire to help reduce the U-values in the houses and make them super energy efficient. Specifying H+H Solar Grade Blocks in particular was part of the housebuilder’s plan to make the homes as desirable as possible, a plan that seemed to work as almost all of the homes were sold before completion.

It’s clear that building energy efficient homes pays, and using H+H Solar Grade Blocks is an ideal way to ensure low carbon living starts with the building fabric.
